Changelog

All notable changes to this package will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[2.3.2] - 2023-04-28

Changed

• Changed XRI project validation to only log errors to the console, not warnings.
• Updated XRPokeFollowAffordance smoothing property default from 8 to 16 to make it feel more responsive.

Fixed

• Added additional checks against AR Foundation 5.0 and newer so deprecation messages and the use of the newer XR Origin (AR) is hidden when using AR Foundation 4.2 and older.
• Fixed GC allocations produced each frame by XRPokeInteractor.UpdateUIModel.
• Fixed frame-timing for Locomotion Input Tests when running in batch mode.
• XRInteractableAffordanceStateProvider Fixes:
  • Activated state was lower priority than selected, which because select is not exited, this was causing issues with it not appearing.
  • There were some racing coroutines between select and activate, and now trigger a new animation blocks previous animations
  • Leaving the select state cancels select animations that might not have completed
  • Leaving activated state cancels activate animations that might not have completed
• Fixed repeat audio issue in the AudioAffordanceReceiver by adding extra conditions which treat select as a modifier to hover, and activated as a modifier to select. Doing this prevents triggering repeat audio clips that shouldn't fire, like releasing the activate trigger, or releasing the select trigger while still hovering.
• Fixed XRPokeLogic issue where poking from behind objects would sometimes trigger select incorrectly.
• Fixed XRPokeLogic issue where depth percent was incorrectly calculated using an exponential value which would result in poke buttons feeling disconnected from the poke interactor position.

[2.3.1] - 2023-03-27

Added

• Added System Gesture Detector component to the Hands Interaction Demo sample to add system gesture and menu palm pinch gesture events. Added sound upon menu press as an example. Added Aim Flags input actions to the XRI Default Input Actions in the Starter Assets sample to support this.
• Added Interaction filters documentation for IXRHoverFilter, IXRSelectFilter, IXRInteractionStrengthFilter, and the corresponding filter delegates with examples.

Changed

• Changed the Poke Gesture Detector component in the Hands Interaction Demo sample to no longer end the poke gesture when hand tracking is lost. This fixes the Ray Interactor line visual reappearing when hand tracking is lost while doing the poke gesture.
• Changed XRInteractorReticleVisual to ensure consistent attempts to align the reticle prefab's z axis with the transform.up of the XROrigin when AlignPrefabWithSurfaceNormal is true and aligning with a non-horizontal surface.
• Changed XRInteractorReticleVisual to align the reticle prefab's z axis with the forward direction of the reticle's interactor when AlignPrefabWithSurfaceNormal is true and aligning with a horizontal surface.
• Updated installation documentation with convenience links for installing the XRI package on older versions of Unity 2021 where the package was not included in the main Editor manifest.
• Changed so UGUI poke interactions are now considered to be blocking interactions for interaction groups. This allows rays to be properly hidden when hovering or selecting a UGUI canvas with poke.
• Changed to use velocity estimation of poke interactor to add an extra validation mechanism in the XR Poke Filter hover validation check to allow poke selection to occur in cases where it was previously rejected, while still preventing poking from behind and other non-desireable cases.
• Changed to cache poke selection validation check so that it's easier to hold a poke when the selection conditions are met. This makes scrolling UGUI canvases easier and makes poke interactions feel more consistent.
• Changed AR Scale Interactable so changing the Min Scale and/or Max Scale during runtime will keep the current object scale if still within range instead of resizing the object to keep the same scale ratio.

Fixed

• Fixed the Hands Interaction Demo sample to wait to activate the controller GameObjects until they are reconnected instead of each time hand tracking is lost. Also fixed the controllers appearing at the origin if they have never been tracked.
• Fixed the Hands Interaction Demo sample so it disables the hand interactors while doing a system gesture (such as a user looking at their open palm at eye level).
• Fixed warning about a self-intersecting polygon in the Frame.fbx model in the Hands Interaction Demo sample.
• Fixed warning in Hands Interaction Demo sample about obsolete API usage coming from the hands subsystem.
• Fixed XRSimulatedController and XRSimulatedHMD to have identifying characteristics information in the capabilities field of their corresponding InputDeviceDescription. (XRIT-50)
• Fixed an issue in the XRController class where the inputDevice property was not reinitialized when the controllerNode property was changed. (XRIT-52)
• UGUI ray interactions are now correctly blocked when interaction groups block ray interactions and the ray is hidden.
• Fixed an issue with TrackedDeviceGraphicRaycaster, when using the XRPokeInteractor on UGUI canvases with different sort orders, where interaction was blocked on all but the highest Order in Layer valued canvas. (XRIT-48)
• Fixed an issue with TrackedDeviceGraphicsRaycaster, where opening a dropdown would block all other UGUI canvases to become non-interactable with an XRPokeInteractor until the dropdown was closed.
• Fixed the Starter Assets and Hands Interaction Demo prefabs which contained components and shaders with a mix of both Built-in Render Pipeline and Universal Render Pipeline. They are all now using Built-in Render Pipeline for consistency.
• Fixed XRInteractorReticleVisual incorrect rotation around y axis when aligning prefab to surface normal. (XRIT-18)
• Fixed XRInteractorReticleVisual incorrect rotation when AlignPrefabWithSurfaceNormal is false.
• Fixed XRInteractorReticleVisual inconsistent rotation when AlignPrefabWithSurfaceNormal and DrawOnNoHit are true but there is no active hit.
• Fixed UIInputModule issue where tracked devices cannot drag on UI elements when Cursor.lockState is set to Locked.

[2.3.0] - 2023-02-17

Added

• Added a Raycast Snap Volume Interaction property to control whether the XR Ray Interactor will collide with or ignore trigger snap colliders from an XR Interactable Snap Volume (used by gaze assistance). This allows a user to set Raycast Trigger Interaction to Ignore but still collide with trigger colliders that are associated with a snap volume.
• Added options to XR Poke Follow Affordance in the Starter Assets sample to apply the follow animation if the poke target is a child and to clamp the follow target to a maximum distance from the poke target.
• Added an XR Poke Follow Affordance to the TextButton prefab in the Starter Assets sample so that the button graphics can move in response to poke.
• Added Tracking State and Is Tracked input actions to the XRI Default Input Actions in the Starter Assets sample.
• Added Meta Gaze Adapter sample to allow developers to request permission and initialize eye tracking for the Meta Quest Pro.
• Added Hands Interaction Demo sample to demonstrate interactions with hand tracking.
• Added poke interaction examples to the DemoScene in the Starter Assets sample.
• Added ability to customize the layer mask and trigger interaction when the XR Poke Interactor performs the physics sphere overlap call.
• Added documentation regarding behavior when Select Action Trigger is set to State on XR Direct Interactor and XR Ray Interactor.

Changed

• Changed the Stop Manipulation action (default binding Escape) in the XR Device Simulator to always stop manipulation every time it is pressed instead of cycling between None and FPS mode. Trigger the Cycle Devices action (default binding Tab) to switch back to FPS mode instead.
• Changed Ray Interactor prefab in the Starter Assets sample to enable Treat Selection As Valid State on the XR Interactor Line Visual.
• Changed the GameObject > XR > Grab Interactable menu item to set the Rigidbody Interpolate property on the created GameObject to Interpolate.
• Changed the Rigidbody Interpolate property from None to Interpolate in each of the Starter Assets sample grab interactable prefabs.
• Changed the default value of the Color Property Name property on the Color Material Property Affordance Receiver component to an empty string instead of "_BaseColor". An empty string will now use either "_BaseColor" or "_Color" depending on the current render pipeline to add support for the Built-In Render Pipeline.
• Changed GetValidTargets on each interactor type to return an empty list when the interactor is disabled.
• Changed ActionBasedControllerManager in Starter Assets sample to make use of XR Interaction Group and removed some unused serialized fields.
• Changed XR Origin Preconfigured in Starter Assets sample so it instantiates the controller model prefab at runtime instead of being in the prefab hierarchy to make it easier for users to override the model used.
• Changed Teleport Interactor in Starter Assets sample so it instantiates the reticle prefabs at runtime instead of being in the prefab hierarchy to make it easier for users to override the reticle used.
• Changed com.unity.xr.core-utils dependency to 2.2.0.

Fixed

• Fixed Teleportation Anchor incorrectly triggering a teleport when the Ray Interactor stops pointing at the anchor when it no longer has any ray cast hits.
• Fixed Starter Assets sample prefabs and DemoScene to have the Gaze Interactor prefab.
• Fixed XRPokeInteractor so it uses the targetFilter for filtering the valid targets returned by GetValidTargets.
• Fixed the Fix button for project validation issue "Interaction Layer 31 is not set to 'Teleport'" not persisting to the settings asset when closing the Unity Editor.
• Fixed missing references in device simulator UI button images by assigning to null.
• Fixed the PokeStateData that is generated from UI poke interaction so that its axisAlignedPokeInteractionPoint is relative to the world position of the target transform.
• Fixed broken click animations in XRInteractableAffordanceStateProvider.
• Fixed XR Device Simulator so it will use the new main camera if the previous one is disabled or destroyed.
• Fixed issue where AR gestures did not take into account UI in ARBaseGestureInteractable behaviors (such as AR Placement Interactable) by adding an excludeUITouches property, which is enabled by default.
• Fixed potential invalid stayed colliders list in XRDirectInteractor and XRSocketInteractor when the interactor is disabled while in contact with a collider.
• Fixed hover and select events being incorrectly fired when an XRDirectInteractor or XRSocketInteractor GameObject or component is disabled while in contact with an interactable, moved away from the interactable, and then enabled.
• Fixed XR Poke Interactor to query the local PhysicsScene instead of using static physics calls.
• Fixed poke in UI scrolling in a scroll view outside of the viewport by ensuring the Tracked Device Graphic Raycaster respects the alpha hit test threshold.
• Fixed the Teleport Anchor prefab in Starter Assets to place the teleport destination at the top of the platform, fixing a bump that would occur when moving with locomotion after teleporting.

[2.3.0-pre.1] - 2022-12-07

Added

• Added new Affordance System. This introduces the XRI Affordance state provider, which connects to an XR Interactable to determine new affordance states, which then power Affordance Receivers to animate tweens using Affordance Theme scriptable Objects. This can be used for audio, ui, material and other kinds of animation tweens, reactive to interaction state changes, all powered by the Job System.
• Added an option to Edit > Project Settings > XR Interaction Toolkit to automatically instantiate the prefab in the XR Device Simulator sample.
• Added XR Interaction Group component, which allows only one member Interactor or Group within the Group to be interacting at a time.
• Added the option Disable Visuals When Blocked In Group to XR Base Interactor, which controls whether to disable the Interactor's visuals when the Interactor is part of an Interaction Group and is unable to interact due to active interaction by another Interactor in the Group. This option is enabled by default.
• Added an XR Interaction Group to each hand in the XR Origin Preconfigured prefab in the Starter Assets sample. Each Group prioritizes Direct interaction over Ray interaction.
• Added a runtime UI for the XR Device Simulator. Users can now also move the player position around the physical play space using WASD and Q/E to simulate the user walking around. Reimport the XR Device Simulator sample to access this new functionality and UI.
• Added ability to control the tracking state of the simulated devices in the XR Device Simulator Inspector window.
• Added properties to XR Device Simulator to control the [0.0, 1.0] amount of the simulated grip and trigger inputs when those controls are activated.
• Added lazy follow functionality for UI which can be enabled by adding the LazyFollow component to a GameObject.
• Added IXRInteractionStrengthInteractor and IXRInteractionStrengthInteractable interfaces that are implemented by XRBaseInteractor and XRBaseInteractable, respectively. These add additional properties and methods related to interaction strength, which conveys a variable (that is, analog) selection interaction strength between an interactor and interactable. This is typically based on a motion controller's grip or trigger amount, or based on a poke depth for those interactable objects that support being poked.
• Added the IXRInteractionStrengthFilter interface. Instances of this interface can be added to Interactables to extend their interaction strength computation without needing to create a derived class.
• Added IsHovered and IsSelected methods to XRBaseInteractable that works similarly to IsHovering and IsSelecting on XRBaseInteractor for querying whether a specific interactor is hovering or selecting that interactable.
• Added XRPokeInteractor and XRPokeFilter classes that provide basic poking functionality for both hands and controllers.
• Added XR Poke Follow Affordance component in the Starter Assets sample to control the smooth visual pressing of a Transform component (such as a button, for example) driven by the current select value of a poke interaction.
• Added XR General Grab Transformer which supports moving and rotating unconstrained with one or two interactors, and scaling when using two interactors.
• Added XRGazeInteractor, driven by either eye-gaze or head-gaze pose information. This allows a developer to use eye or head gaze to hover or select by dwelling on interactables.
• Added XRInteractableSnapVolume to allow snapping a ray interactor to a nearby target interactable. This can be combined with the XRGazeInteractor to achieve gaze-assisted hover and selection.
• Added Gaze Configuration properties to XRBaseInteractable related to gaze interactions, automatic selection and deselection from hover, and gaze-assisted hover and selection.
• Added a drawOnNoHit property to XRInteractorReticleVisual that forces the reticle to draw when no ray cast hits are detected.
• Added a snapEndpointIfAvailable property to XRInteractorLineVisual to allow bending the visual ray towards a specified target point, such as guided by an XRInteractableSnapVolume for more user-friendly object selection.
• Added Eye Gaze Position and Eye Gaze Rotation actions to the XRI Default Input Actions asset along with corresponding XRI Default Gaze Controller preset to the Starter Assets sample.
• Added an Integer Fallback Composite binding for Input System input actions, which is useful for a tracking state action. This composite works similarly to the Vector 3 Fallback and Quaternion Fallback Composite bindings.
• Added GetCustomReticle method to XRBaseInteractable to allow lookup of the custom reticle associated with a particular Interactor.
• Added Poke Interactor to each hand in the Complete XR Origin Set Up prefab in Starter Assets

Changed

• Changed the default grab transformers from XR Single Grab Free Transformer and XR Dual Grab Free Transformer to XR General Grab Transformer. This new grab transformer does not respond to the pose of the Attach Transform of the XR Grab Interactable changing while grabbed. If you need to modify the pose after being grabbed, you will need to add a different grab transformer from the Component > XR > Transformers menu.
• Changed GameObject > XR > Grab Interactable to add the XR General Grab Transformer component by default.
• Changed XR Grab Interactable to re-initialize the dynamic attach pose when changing from multiple grabs back to a single grab by default. Disable Reinitialize Every Single Grab (reinitializeDynamicAttachEverySingleGrab) for previous behavior.
• Changed XRDeviceSimulator to destroy itself if another instance already exists at runtime.
• Changed XR Device Simulator to initialize the simulated controllers to position them in front of the HMD instead of at (0, 0, 0).
• Changed XR Device Simulator to start manipulating the HMD and controllers as if the whole player was turning their torso, similar to a typical FPS style configuration, to simplify its use. Press Tab to cycle between manipulating all devices in this mode, the left controller individually, and the right controller individually.
• Changed GameObject > XR > XR Origin (VR) to set the Tracking State Input property on the Tracked Pose Driver of the Main Camera on versions of Input System that support it.
• Changed XRSimulatedController and XRSimulatedHMD to report support for updating during the before render phase.
• Changed DefaultExecutionOrder of the XRInteractionManager from -100 to -105.
• Changed InteractorRegisteredEventArgs by adding a containingGroupObject property of type IXRInteractionGroup which is set when the Interactor is contained in an Interaction Group.
• Changed XRBaseInteractable initialization logic of the IXRInteractable.colliders list to exclude trigger colliders when no colliders are set in the Inspector window.
• Changed XRInteractableUtility.TryGetClosestCollider and XRInteractableUtility.TryGetClosestPointOnCollider to ignore trigger colliders.
• Changed the default value of Select Action Trigger (XRBaseControllerInteractor.selectActionTrigger) on interactors from State to State Change.
• Changed com.unity.inputsystem dependency to 1.4.4.
• Changed com.unity.xr.core-utils dependency to 2.2.0-pre.2.
• Changed com.unity.xr.legacyinputhelpers dependency to 2.1.10.

Fixed

• Fixed Tracked Device Graphic Raycaster to use the correct ray cast method when Check for 2D Occlusion is enabled, and changed it to use the local PhysicsScene2D.
• Fixed issue with RegistrationList and SmallRegistrationList where unregistering and then registering an item that already exists in the registered snapshot would result in the item being counted twice due to being added to the buffered add list.
• Fixed issue with RegistrationList and SmallRegistrationList where unregistering an item that was not yet flushed to the registered snapshot would result in the list returning an incorrect flushedCount due to being incorrectly added to the buffered remove list instead of just removing from the buffered add list.
• Fixed issue with RegistrationList not reporting the registration status of items added via MoveItemImmediately.
• Fixed Grab Transformers (that derive from XRBaseGrabTransformer) to skip automatic registration specified by registrationMode when it has already been added to the XRGrabInteractable. It previously only checked the Starting Single/Multiple Grab Transformers lists.
• Fixed expansion state of Select Filters in the Inspector window reusing the Hover Filters state in some cases.
• Fixed XRRayInteractor null reference exception that causes editor spam when sample points are deleted upon hot-reload.
• Fixed incorrectly false return values for AddCustomReticle and RemoveCustomReticle on the XRInteractorLineVisual class.

[2.2.0] - 2022-09-30

Added

• Added ability for the target position, rotation, and scale of an XR Grab Interactable to be calculated by another component. Developers can derive from XRBaseGrabTransformer and add those components to the same GameObject as the XR Grab Interactable. The existing logic was moved to XRSingleGrabFreeTransformer. For more information, see Grab transformers.
• Added properties allowHoverAudioWhileSelecting and allowHoverHapticsWhileSelecting to XRBaseControllerInteractor, which control whether to allow the Interactor from playing audio and haptics, respectively, in response to a Hover event if the Hovered Interactable is currently Selected by the Interactor.
• Added property stopLineAtSelection to XRInteractorLineVisual, which controls whether the line will stop at the attach point of the closest interactable selected by the interactor, if there is one.
• Added property treatSelectionAsValidState to XRInteractorLineVisual, which forces the use of valid state visuals while the interactor is selecting an interactable, whether or not the interactor has any valid targets.
• Added support for teleportation directionality so that users can specify the direction they will face when teleportation finishes.
  • Added a Teleport Direction input action for each hand in the XRI Default Input Actions asset in the Starter Assets sample.
  • Added the property anchorRotationMode as an option for how XRRayInteractor controls anchor rotation. RotateOverTime is the existing and default behavior, which is useful for rotating a held object. The other option is MatchDirection, which is useful for controlling teleportation direction by matching rotation to the direction of the 2-dimensional input.
  • Added input options for directional anchor rotation to ActionBasedController and XRController.
  • Added the property matchDirectionalInput as an option for a BaseTeleportationInteractable to apply directional input (based on anchor rotation) when its matchOrientation is set to WorldSpaceUp or TargetUp.
  • Added an interface IXRReticleDirectionProvider for teleportation interactables to override the direction of the reticle.
• Added Fixed update type to XRBaseController which is in sync with MonoBehavior.FixedUpdate.
• Added the IXRTargetPriorityInteractor interface that allow Interactors to monitor the Interactables priority for selection in the current frame. There are different monitoring options (None, Highest Priority Only, and All) with different performance tradeoffs.
• Added the XRInteractionManager.IsHighestPriorityTarget method to check if an Interactable is the highest priority candidate for selection of an Interactor (IXRTargetPriorityInteractor) in the current frame, which is useful for custom affordance feedback.
• Added the IXRHoverFilter interface. Instances of this interface can be added to Interactors, Interactables, or to the Interaction Manager to extend their hover validations without needing to create a derived class.
• Added the IXRSelectFilter interface. Instances of this interface can be added to Interactors, Interactables, or to the Interaction Manager to extend their select validations without needing to create a derived class.
• Added color gradient and reticle options to XR Interactor Line Visual for when the Interactor has a valid target but it selection is blocked. These can be configured by setting the properties Blocked Color Gradient and Blocked Reticle, respectively.
• Added the public method CanHover to XRInteractionManager, which checks whether a given Interactor is able to hover a given Interactable.
• Added the public method CanSelect to XRInteractionManager, which checks whether a given Interactor is able to select a given Interactable.
• Added the public method IsHoverPossible to XRInteractionManager, which checks whether a given Interactor would be able to hover a given Interactable if the Interactor were in a state where it could hover.
• Added the public method IsSelectPossible to XRInteractionManager, which checks whether a given Interactor would be able to select a given Interactable if the Interactor were in a state where it could select.
• Added Enable Fly option to Continuous Move Provider, which allows for unconstrained movement in any direction.
• Added properties filterSelectionByHitNormal and upNormalToleranceDegrees to BaseTeleportationInteractable, which are used to configure whether a user can teleport to a location if the hit normal is not aligned with the interactable's up vector.
• Added Grab Move Provider and Two Handed Grab Move Provider, which provide locomotion based on tracked controller position while a button is held. Grab Move Provider provides translation of the user, and Two Handed Grab Move Provider provides translation, yaw rotation, and uniform scaling of the user.
  • Added a Grab Move input action for each hand in the XRI Default Input Actions asset in the Starter Assets sample.
  • Added XRI Default Left Grab Move and XRI Default Right Grab Move presets to the Starter Assets sample.
  • Added ConstrainedMoveProvider base class for GrabMoveProvider and TwoHandedGrabMoveProvider, to hold logic for constrained movement with a CharacterController.

Changed

• Changed XR Grab Interactable to support being selected by multiple Interactors. To enable that ability in the Inspector window, set Select Mode to Multiple. If your derived class does not properly handle multiple selections and you want to disable the Multiple option, you will need to add [CanSelectMultiple(false)] to your component script.
• Ray casts now query the local PhysicsScene instead of using static Physics routines which uses the default physics scene. Gesture classes that perform ray casts use the camera's scene, and components that perform ray casts use its scene during Awake.
• Changed XRInteractionManager by adding the Awake method. Users who had already implemented Awake in derived classes will need to call the base method.
• Creating a new XR Origin (VR) now automatically adds an Input Action Manager component and sets the Action Assets to XRI Default Input Action.inputactions asset if available from the Starter Assets sample package.
• Move speed in Continuous Move Providers and line width in XR Interactor Line Visual are now scaled by the scale of the XR Origin.
• Changed the Ray Interactor GameObject created through the GameObject > XR create menu to have a Sorting Group to make it render in front of UI and changed the TunnelingVignette prefab in the Tunneling Vignette sample to have a Sorting Group to make it render in front of the Line Renderer of a Ray Interactor.
• Changed minimum supported version of the Unity Editor from 2019.4 to 2020.3 (LTS).

Fixed

• Fixed issue where the last point in the curve rendered by XR Interactor Line Visual would not always be continuous with the rest of the curve (for example when sphere cast is used).
• Fixed issue where using the MockHMD XR Plugin package with the XRDeviceSimulator would cause the device simulator's rotation to be overwritten. This issue can also be fixed by upgrading the Input System package to 1.4.1+.
• Fixed issue where XRInteractorReticleVisual script did not properly detect ray casts with UI objects. (XRIT-18)
• Fixed an issue with throwing physics on Quest devices where bad frame-timing would cause unexpectedly high velocities to be applied.
• Fixed "Retrieving array element that was out of bounds" error when viewing the Tunneling Vignette Controller in the Inspector window when the Locomotion Vignette Providers list is empty.
• Fixed XR Interactor Line Visual so it deactivates the current reticle GameObject when the behavior is enabled or disabled.

[2.1.1] - 2022-07-29

Added

• Added enableBuiltInActionsAsFallback property on XRUIInputModule to provide a fallback default behavior out of the box when using the new Input System as the Active Input Handling.
• Added missing documentation for UI Setup that specifies how to perform object occlusion for UI objects when using the Tracked Device Graphics Raycaster component.
• Added a warning message to the Inspector of XR Interactor Line Visual and XR Interactor Reticle Visual when the Reticle has a Collider which may disrupt the ray cast. This added an XRInteractorReticleVisualEditor class.

Changed

• Changed the dynamic attach behavior of XR Grab Interactable so it only ignores the Match Position property when being grabbed by an XR Ray Interactor with Force Grab enabled instead of ignoring both Match Position and Match Rotation. This lets you bring the object to your hand while keeping the rotation if configured. To make it easier to override the dynamic attach properties for a selecting interactor, the protected methods ShouldMatchAttachPosition, ShouldMatchAttachRotation, and ShouldSnapToColliderVolume were added to XRGrabInteractable.
• Updated Editor tooltip and documentation to clarify how the Stop Line At First Raycast Hit property works on the XR Interactor Line Visual component. (XRIT-4)

Fixed

• Fixed rendering of the Tunneling Vignette causing issues like the Line Renderer cutting short by setting ZWrite Off in the shader. If the sample has already been imported into your project, you will need to import again to get the update.
• Fixed so the TunnelingVignette material asset does not get modified by the TunnelingVignetteController.
• Fixed GetValidTargets performance when there are several Interactors in the scene hovering one or no Interactables.
• Fixed missing input binding for the Move action in the XRI RightHand Locomotion Action Map in the XRI Default Input Actions asset inside the Starter Assets sample.
• Fixed the Rotate Anchor and Translate Anchor input bindings in the XRI Default Input Actions asset to be simpler by not using composite bindings.
• Fixed CharacterControllerDriver so it will try to find the ContinuousMoveProviderBase on other active GameObjects if it isn't on the same GameObject.
• Fixed regression introduced with version 2.1.0-pre.1 so Anchor Control on XR Ray Interactor does not base logic on an XR UI Input Module property.
• Fixed the GameObject > XR create menu items which find existing components sometimes using invalid or deleted GameObjects.
• Fixed the GameObject > XR > UI Event System create menu item destroying the existing GameObject upon Undo when it already existed in the scene.
• Fixed CreateUtilsTests to be internal instead of public.

[2.0.3] - 2022-07-26

Fixed

• Fixed the simulated HMD and controllers so they no longer reset to origin after switching focus away and back to the Unity Editor. (1409417)
• Fixed warnings about setting velocities of a kinematic body when updating an XR Grab Interactable with Movement Type set to Kinematic.
• Fixed UIInputModule so it will use the new Main Camera if the previous one is disabled when UIInputModule.uiCamera is not set.
• Fixed warning in the Inspector window for interactors missing the XR Controller component when the GameObject is deactivated by changing the find method to include inactive GameObjects.
• Fixed XR Interactor Line Visual so it will instantiate the Reticle GameObject when it is a Prefab asset so it does not modify the asset on disk.
• Fixed UIInputModule to support EventSystem IPointerMoveHandler for Unity 2021.1 and newer. Also added the corresponding pointerMove event to UIInputModule to allow the pointer move events to be globally handled.

[2.1.0-pre.1] - 2022-05-02

Added

• Added properties to XR Grab Interactable to use dynamic attach transforms so the grab pose will be based on the pose of the Interactor when the selection is made. You can enable the Use Dynamic Attach property to keep the object in the same position and rotation when grabbed. (1373337)
• Added filtering for interactions to help determine the intent of the user. The new abstractions XR Target Filter and XR Target Evaluator let users configure and extend the logic of how an Interactor ranks an Interactable from a list of valid ones, specifically in the GetValidTargets method. Several different evaluators are included in this update, and custom ones can be created. This makes it easier to customize the Interactor without needing to create a derived behavior.
• Added the XRBaseInteractable.distanceCalculationMode property. This give users the ability to configure how an Interactable calculates its distance to a location, such as to an Interactor for sorting its valid targets, at varying tradeoffs between accuracy and performance.
• Added the XRBaseInteractable.getDistanceOverride property that lets users assign a method to be called when the Interactable is performing a distance calculation to a location, which is used when the Interactor is ordering its valid targets. This property makes it easier to customize the Interactable without needing to create a derived behavior.
• Added IsOverUIGameObject function to XRRayInteractor that does a simple check to see if the ray cast result is hitting a UI GameObject.
• Added InputActionReference properties to the XRUIInputModule for left/right/middle clicks, navigation move, submit, cancel, scroll and pointer movement actions. This allows for greater flexibility and customization of what devices can drive UI input when using the XRUIInputModule.
• The XRI Default Input Actions asset in the Starter Assets sample package now includes an XRI UI Action Map for UI-specific Input Actions. Also included is a Preset asset to quickly map the actions onto the XRUIInputModule component.
• Added a Tunneling Vignette sample. It contains assets to let users set up and configure the tunneling vignette as a comfort mode intended to mitigate motion sickness in VR.
• Added a Tunneling Vignette Controller component used for driving the vignette material included with the Tunneling Vignette sample. Locomotion Provider components can be drag-and-dropped into a list of Locomotion Providers that will trigger the tunneling vignette effect. A custom inspector allows previewing each effect for the corresponding Locomotion Provider.
  • Added ITunnelingVignetteProvider interface to allow custom behaviors to control the vignette effect.
  • Added a LocomotionPhase enum in LocomotionProvider that can be used to describe different phases of a locomotion for use with the tunneling vignette. Added code in ContinuousMoveProviderBase, ContinuousTurnProviderBase, SnapTurnProviderBase, and TeleportationProvider to compute their LocomotionPhase.
  • Added a Delay Time property to the Teleportation Provider and Snap Turn Provider components to support customization of timing for use with fading in the tunneling vignette.

Changed

• Updated code paths with macro protections around InputSystem or Input Manager based code to prevent attempted usage when either one is not active.
• Scroll speed when using the ScrollWheel Input System Action is now being divided by 20 pixels per line instead of 120 pixels per line to match the InputSystemUIInputModule scrolling speed.
• Changed XRSocketInteractor hover mesh pose calculation to only ignore the current pose of the attach transform for XRGrabInteractable when Use Dynamic Attach is disabled instead of for all types of IXRSelectInteractable.
• Changed XRControllerRecorder.recording from internal to public.

Fixed

• Fixed UIInputModule so pointer clicks set the correct button (left/right/middle) for the EventSystem in the PointerEventData.
• Fixed compilation errors on platforms such as Game Core where ENABLE_VR is not currently defined.

[2.0.2] - 2022-04-29

Fixed

• Fixed wrong offset when selecting an XRGrabInteractable with Track Rotation disabled when the Attach Transform had a different rotation than the Interactable's rotation. This configuration was not covered in the related fix made previously in version 2.0.0-pre.6. (1361271)
• Fixed XR Socket Interactor hover mesh position and rotation for an XR Grab Interactable with Track Position and/or Track Rotation disabled.
• Fixed the simulated controllers not working in projects where the Scripting Backend was set to IL2CPP.
• Fixed the simulated HMD deviceRotation not being set. It now matches the centerEyeRotation.
• Fixed the GameObject > XR > AR Annotation Interactable menu item when AR Foundation is installed to add the correct component.
• Fixed UIInputModule so it uses and resets PointerEventData.useDragThreshold to allow users to ignore the drag threshold by implementing IInitializePotentialDragHandler. It was previously being ignored and causing sliders and scrollbars to incorrectly use a drag threshold.

[2.0.1] - 2022-03-04

Changed

• Changed the XRI Default Input Actions asset in the Starter Assets sample by removing the primaryButton bindings from Teleport Select and Teleport Mode Activate. If you want to restore the old behavior of both bindings, add an Up\Down\Left\Right Composite, reassign the Up composite part binding, and add the Sector interaction for that direction. The actions were also reorganized into additional Action Maps.

Fixed

• Fixed regression introduced with version 2.0.0 so the hover mesh draws in the correct location when the Interactable's Attach Transform is not a child Transform or deep child Transform.
• Fixed the XRI Default Input Actions asset in the Starter Assets sample showing the warning "(Incompatible Value Type)" on the bindings for Teleport Select and Teleport Mode Activate by changing the action type from Button to Value with an expected control type of Vector2. The sample needs to be imported again if you already imported it into your project for you to see these changes.
• Fixed missing UNITY_INCLUDE_TESTS constraint in test assembly definition.

[2.0.0] - 2022-02-16

Added

• Added a warning message to the Inspector of XRGrabInteractable with non-uniformly scaled parent. A child XRGrabInteractable with non-uniformly scaled parent that is rotated relative to that parent may appear skewed when you grab it and then release it. See Limitations with Non-Uniform Scaling. (1228990)
• Added support for gamepad and joystick input when using the XR UI Input Module for more complete UGUI integration.

Changed

• Changed sockets so selections are only maintained when exclusive. XRSocketInteractor.CanSelect changed so that sockets only maintain their selection when it is the sole interactor selecting the interactable. Previously, this was causing interactables that support multiple selection to not get released from the socket when grabbed by another interactor, which is not typically desired.
• Changed sockets so the hover mesh is positioned at the original attach transform pose for selected interactables. This fixes the case where the hover mesh would be at the wrong location when the attach transform is dynamically modified when an XR Grab Interactable is grabbed.
• Changed XRDirectInteractor and XRSocketInteractor by adding an OnTriggerStay method to fix an issue where those interactors did not detect when a Collider had exited in some cases where OnTriggerExit is not invoked, such as the Collider of the interactable being disabled. Users who had already implemented OnTriggerStay in derived classes will need to call the base method.
• Changed GestureTransformationUtility.Raycast default parameter value of trackableTypes from TrackableType.All to TrackableType.AllTypes to fix use of deprecated enum in AR Foundation 4.2. The new value includes TrackableType.Depth.
• Renamed the Default Input Actions sample to Starter Assets.
• Updated the manual to move most sections to separate pages.
• Moved some components from the Component > Scripts menu into Component > XR, Component > Event, and Component > Input.
• Changed com.unity.xr.core-utils dependency to 2.0.0.

Fixed

• Fixed XRDirectInteractor and XRSocketInteractor still hovering an XRGrabInteractable after it was deactivated or destroyed.
• Fixed properties in event args for select and hover being incorrect when the same event is invoked again during the event due to the instance being reused for both. An object pool is now used by the XRInteractionManager to avoid the second event from overwriting the instance for the first event.
• GC.Alloc calls have been reduced: ray interactors with UI interaction disabled no longer allocate each frame, XR UI Input Module now avoids an allocating call, and AR gesture recognizers no longer re-allocate gestures when an old one is available.
• Fixed Editor classes improperly using enumValueIndex instead of intValue in some SerializedProperty cases. In practice, this bug did not affect users since the values matched in those cases.
• Fixed issue where EventManager.current.IsPointerOverGameObject would always return false when using XRUIInputModule for UI interaction. (1387567)
• Fixed XR Tint Interactable Visual from clearing the tint in some cases when it was set to tint on both hover and selection. Also fixed the case when the interactable supports multiple selections so it only clears the tint when all selections end. It will now also set tint during Awake if needed.
• Fixed ARTests failing with Enhanced touches due to version upgrade of Input System.
• Fixed use of deprecated methods and enum values in GestureTransformationUtility when using AR Foundation 4.1 and 4.2.

[2.0.0-pre.7] - 2022-01-31

Fixed

• Fixed ScriptableSettings so it no longer logs to the console when creating the settings asset.

[2.0.0-pre.6] - 2021-12-15

Fixed

• Fixed wrong offset when selecting an XRGrabInteractable with Track Rotation disabled. (1361271)
• Fixed XRInteractorLineVisual causing the error "Saving Prefab to immutable folder is not allowed". Also fixed the undo stack by no longer modifying the Line Renderer during Reset. (1378651)
• Fixed UI interactions not clicking when simultaneously using multiple Ray Interactors. (1336124)
• Fixed Raycast Padding of Graphic UI objects not being considered by TrackedDeviceGraphicRaycaster. (1333300)
• Fixed OnEndDrag not being called on behaviors that implement IEndDragHandler when the mouse starts a drag, leaves the bounds of the object, and returns to the object without releasing the mouse button when using the XRUIInputModule upon finally releasing the mouse button.
• Fixed runtime crashing upon tapping the screen when using AR touch gestures in Unity 2021.2 in projects where the Scripting Backend was set to IL2CPP.
• Fixed MissingReferenceException caused by XRBaseInteractable when one of its Colliders was destroyed while it was hovering over a Direct Interactor or Socket Interactor.
• Fixed obsolete message for XRControllerState.poseDataFlags to reference the correct replacement field name.

[2.0.0-pre.5] - 2021-11-17

Fixed

• Fixed name of the profiler marker for PreprocessInteractors.

[2.0.0-pre.4] - 2021-11-17

Added

• Added ability to change the MovementType of an XRGrabInteractable while it is selected. The methods SetupRigidbodyDrop and SetupRigidbodyGrab will be invoked in this case, you can check if the XRGrabInteractable it's not selected or use the methods Grab and Drop to perform operations that should only occur once during the select state.

Changed

• Changed so the Interaction Layer Mask check is done in the XRInteractionManager instead of within XRBaseInteractor.CanSelect/XRBaseInteractable.IsSelectableBy and XRBaseInteractor.CanHover/XRBaseInteractable.IsHoverableBy.
• Changed com.unity.inputsystem dependency from 1.0.2 to 1.2.0.
• Changed com.unity.xr.core-utils dependency from 2.0.0-pre.3 to 2.0.0-pre.5.
• Changed com.unity.xr.legacyinputhelpers dependency from 2.1.7 to 2.1.8.
• Changed XRHelpURLConstants from public to internal.

Fixed

• Updated the property names of XROrigin to adhere to PascalCase.

[2.0.0-pre.3] - 2021-11-09

Added

• Added XR Interaction Toolkit Settings to the Edit > Project Settings window to allow for editing of the Interaction Layers. These settings are stored within a new Assets/XRI folder by default.
• Added a Select Mode property to Interactables that controls the number of Interactors that can select it at the same time. This allows Interactables that support it to be configured to allow multiple hands to interact with it at the same time. The Multiple option can be disabled in the Inspector window by adding [CanSelectMultiple(false)] to your component script.
• Added ability to double click a row in the XR Interaction Debugger window to select the Interactor or Interactable.
• Added the ActionBasedController.trackingStateAction property that allows users to bind the InputTrackingState. This new action is used when updating the controller's position and rotation. When not set, it falls back to the old behavior of using the tracked device's tracking state that is driving the position or rotation action.
• Added the interaction float value to the controller state. This will allow users to read the float value from InteractionState, not just the bool value, to drive visuals.
• Added methods to XRBaseInteractor and XRBaseInteractable to return the pose of the Attach Transform captured during the moment of selection (GetAttachPoseOnSelect and GetLocalAttachPoseOnSelect).
• Added a property to XRBaseInteractor and XRBaseInteractable to return the first interactor or interactable during the current select stack (firstInteractableSelected and firstInteractorSelecting).
• Added Allow Hovered Activate option to Ray Interactor and Direct Interactor to allow sending activate and deactivate events to interactables that the interactor is hovered over but not selected when there is no current selection. Override GetActivateTargets(List<IXRActivateInteractable>) to control which interactables can be activated.
• Added teleporting event to BaseTeleportationInteractable (TeleportationAnchor, TeleportationArea). Fires according to timing defined by that type's teleportTrigger.

Changed

• Changed ProcessInteractor so that it is called after interaction events instead of before. Added a new PreprocessInteractor method to interactors which is called before interaction events. Scripts which used ProcessInteractor to compute valid targets should move that logic into PreprocessInteractor instead.

• Changed the signature of all methods with XRBaseInteractor or XRBaseInteractable parameters to instead take one of the new interfaces for Interactors (IXRInteractor, IXRActivateInteractor, IXRHoverInteractor, IXRSelectInteractor) or Interactables (IXRInteractable, IXRActivateInteractable, IXRHoverInteractable, IXRSelectInteractable). This change allows users to completely override and develop their own implementation of Interactors and Interactables instead of being required to derive from XRBaseInteractor or XRBaseInteractable.

      }
  }
  

• Changed Interactors and Interactables so they support having multiple selections, similarly to how they could have multiple components they were either hovering over or being hovered over by.

  Old Pseudocode Snippets	New Pseudocode Snippets
  XRBaseInteractor.selectTarget != null	IXRSelectInteractor.hasSelection
  XRBaseInteractor.selectTarget	// Getting the first selected Interactable IXRSelectInteractor.hasSelection ? IXRSelectInteractor.interactablesSelected[0] : null or using System.Linq; IXRSelectInteractor.interactablesSelected.FirstOrDefault();

  XRBaseInteractable.hoveringInteractors	IXRHoverInteractable.interactorsHovering
  XRBaseInteractable.selectingInteractor	IXRSelectInteractable.interactorsSelecting

  // Example Interactor that overrides a predicate method.
  public class ExampleInteractor : XRBaseInteractor
  {
      // Old code
      public override bool CanSelect(XRBaseInteractable interactable)
      {
          return base.CanSelect(interactable) && (selectTarget == null || selectTarget == interactable);
      }
  
      // New code
      public override bool CanSelect(IXRSelectInteractable interactable)
      {
          return base.CanSelect(interactable) && (!hasSelection || IsSelecting(interactable));
      }
  }
  

• Changed XRInteractionManager methods ClearInteractorSelection and ClearInteractorHover from public to protected. These are invoked each frame automatically and were not intended to be called by external scripts.
• Changed behaviors that used the attachTransform property of XRBaseInteractor and XRGrabInteractable to instead use IXRInteractor.GetAttachTransform(IXRInteractable) and IXRInteractable.GetAttachTransform(IXRInteractor) when possible. Users can override the GetAttachTransform methods to customize which Transform should be used for a given Interactor or Interactable.
• Changed Interactor and Interactable interaction Layer checks to use the new InteractionLayerMask instead of the Unity physics LayerMask. Layers for the Interaction Layer Mask can be edited separately from Unity physics Layers. A migration tool was added to upgrade the field in all Prefabs and scenes. You will be prompted automatically after upgrading the package, and it can also be done at any time by opening Edit > Project Settings > XR Interaction Toolkit and clicking Run Interaction Layer Mask Updater.
• Changed Toggle and Sticky in Select Action Trigger so the toggled on state is now based on whether a selection actually occurred rather than whether there was simply a valid target. This means that a user that presses the select button while pointing at a valid target but one that can not be selected will no longer be in a toggled on state to select other interactables that can be selected.
• Changed Socket Interactor so the hover mesh can appear for all valid Interactable components, not just Grab Interactable components.
• Changed XRRayInteractor.TranslateAnchor so the Ray Origin Transform is passed instead of the Original Attach Transform, and renamed the parameter from originalAnchor to rayOrigin.
• Changed HoverEnterEventArgs, HoverExitEventArgs, SelectEnterEventArgs, and SelectExitEventArgs by adding a manager property of type XRInteractionManager.
• Changed minimum supported version of the Unity Editor from 2019.3 to 2019.4 (LTS).

Deprecated

• Deprecated XRRig which was replaced by XROrigin in a new dependent package XR Core Utilities. XROrigin combines the functionality of XRRig and ARSessionOrigin.
• Deprecated XRBaseInteractor.requireSelectExclusive which was used by XRSocketInteractor. That logic was moved into CanSelect by utilizing the isSelected property of the interactable.
• Deprecated XRRayInteractor.originalAttachTransform and replaced with rayOriginTransform. The original pose of the Attach Transform can now be obtained with new methods (GetAttachPoseOnSelect and GetLocalAttachPoseOnSelect).
• Deprecated GetControllerState and SetControllerState from the XRBaseController. That logic was moved into the currentControllerState property.
• Deprecated XRControllerState.poseDataFlags due to being replaced by the new field XRControllerState.inputTrackingState to track the controller pose state.
• Deprecated the XRControllerState constructor; the inputTrackingState parameter is now required.
• Deprecated AddRecordingFrame(double, Vector3, Quaternion, bool, bool, bool) in the XRControllerRecording; use AddRecordingFrame(XRControllerState) or AddRecordingFrameNonAlloc instead.

Fixed

• Fixed Teleportation Areas and Anchors causing undesired teleports when two different Ray Interactors are pointed at them by setting their default Select Mode to Multiple. By default, a teleport would be triggered On Select Exit, but that would occur when each Ray Interactor would take selection. Users with existing projects should change the Select Mode to Multiple.
• Fixed Sockets sometimes showing either the wrong hover mesh or appearing while selected for a single frame when the selection state changed that frame.
• Fixed Sockets sometimes showing the hover mesh for a single frame after another Interactor would take its selection when the Recycle Delay Time should have suppressed it from appearing.
• Fixed controller's recording serialization losing data when restarting the Unity Editor.
• Fixed releasing XRGrabInteractable objects after a teleport from having too much energy.
• Fixed pixelDragThresholdMultiplier not being squared when calculating the threshold in UIInputModule. To keep the same drag threshold you should update the Tracked Device Drag Threshold Multiplier property of your XRUIInputModule (and your subclasses of UIInputModule) to its square root in the Inspector window; for example, a value of 2 should be changed to 1.414214 (or sqrt(2)). (1348680)

[2.0.0-pre.2] - 2021-11-04

Changed

• Changed package version for internal release.

[2.0.0-pre.1] - 2021-10-22

Changed

• Changed package version for internal release.

[1.0.0-pre.8] - 2021-10-26

Changed

• Changed the setter of XRBaseInteractable.selectingInteractor from private to protected.

Fixed

• Fixed XRBaseController so its default XRControllerState is no longer constructed with a field initializer to avoid allocation when not needed, such as when it is replaced with SetControllerState.
• Fixed XRUIInputModule not processing clicks properly when using simulated touches, such as when using the Device Simulator view. This change means mouse input is not processed when there are touches, matching the behavior of other modules like the Standalone Input Module.
• Fixed Direct Interactor logging a warning about not having a required trigger Collider when it has a Rigidbody.
• Fixed missing dependency on com.unity.modules.physics.
• Fixed the sort order of ray casts returned by TrackedDevicePhysicsRaycaster.Raycast so that distance is in ascending order (closest first). It was previously returning in descending order (furthest first). In practice, this bug did not affect users since EventSystem.RaycastAll would correct the order.

[1.0.0-pre.6] - 2021-09-10

Changed

• Changed ARGestureInteractor.GetValidTargets to no longer filter out Interactable objects based on the camera direction. The optimization method used was faulty and could cause Interactable objects that were still visible to be excluded from the list. (1354009)

Fixed

• Fixed Tracked Device Physics Raycaster so it will include ray cast hits for GameObjects that did not have an event handler. This bug was causing events like IPointerEnterHandler.OnPointerEnter to not be invoked when the hit was on a child Collider that did not itself have an event handler. (1356459)
• Fixed XRBaseInteractable.isHovered so it only gets set to false when all Interactors exit hovering. It was previously getting set to false when any Interactor would exit hovering even if another Interactor was still hovering.
• Fixed use of obsolete properties in TrackedPoseDriver when using Input System package version 1.1.0-pre.6 or newer.
• Fixed the Default Input Actions sample to be compatible with Input System package version 1.1.0 by merging the two bindings for the Turn action into one binding with both Sector interactions.
• Fixed the Socket Interactor hover mesh not matching the actual pose the Grab Interactable would attach to in the case when its attach transform was offset or rotated. Also fixed the pose of child meshes. (1358567)
• Fixed Interactable objects not being considered valid targets for Direct and Socket Interactors when the Interactable was registered after it had entered the trigger collider of the Interactor. Note that Unity rules for Colliders and OnTriggerEnter/OnTriggerExit still applies where the Interactable GameObject being deactivated and then moved will cause the Interactor to miss the trigger enter/exit event. If the object is manipulated in that way, those trigger methods need to be manually called to inform the Direct or Socket Interactor. (1340469)
• Fixed the Trigger Pressed and Grip Pressed buttons not working on the XR Controller (Device-based). They were also renamed to Trigger Button and Grip Button to match the corresponding CommonUsages name.

[1.0.0-pre.5] - 2021-08-02

Added

• Added public events to UIInputModule which correspond to calls to EventSystem.Execute and EventSystem.ExecuteHierarchy to allow the events to be globally handled.
• Added profiler markers to XRInteractionManager to help with performance analysis.
• Added ability for the Animation and Physics 2D built-in packages to be optional.

Changed

• Changed XRBaseInteractable.GetDistanceSqrToInteractor to not consider disabled Colliders or Colliders on disabled GameObjects. This logic is used by XRDirectInteractor and XRSocketInteractor to find the closest interactable to select.

Fixed

• Fixed poor performance scaling of XRInteractionManager as the number of valid targets and hover targets of an Interactor increased. AR projects with hundreds of gesture interactables should see a large speedup.
• Fixed AR Gesture Recognizers producing GC allocations each frame when there were no touches.
• Fixed issue involving multiple Interactables that reference the same Collider in their Colliders list. Unregistering an Interactable will now only cause the Collider association to be removed from the XRInteractionManager if it's actually associated with that same Interactable.
• Fixed the Inspector showing a warning about a missing XR Controller when the Interactor is able to find one on a parent GameObject.

[1.0.0-pre.4] - 2021-05-14

Added

• Added Tracked Device Physics Raycaster component to enable physics-based UI interaction through Unity's Event System. This is similar to Physics Raycaster from the Unity UI package, but with support for ray casts from XR Controllers.
• Added finalizeRaycastResults event to UIInputModule that allows a callback to modify ray cast results before they are used by the event system.
• Added column to XR Interaction Debugger to show an Interactor's valid targets from XRBaseInteractor.GetValidTargets.
• Added property to XR Controller to allow the model to be set to a child object instead of forcing it to be instantiated from prefab.

Changed

• Changed Grab Interactable to have a consistent attach point between all Movement Type values, fixing it not attaching at the Attach Transform when using Instantaneous when the object's Transform position was different from the Rigidbody's center of mass. To use the old method of determining the attach point in order to avoid needing to modify the Attach Transform for existing projects, set Attach Point Compatibility Mode to Legacy. Legacy mode will be removed in a future version. (1294410)
• Changed Grab Interactable to also set the Rigidbody to kinematic upon being grabbed when the Movement Type is Instantaneous, not just when Kinematic. This improves how it collides with other Rigidbody objects.
• Changed Grab Interactable to allow its Attach Transform to be updated while grabbed instead of only using its pose at the moment of being grabbed. This requires not using Legacy mode.
• Changed Grab Interactable to no longer use the scale of the selecting Interactor's Attach Transform. This often caused unintended offsets when grabbing objects. The position of the Attach Transform should be used for this purpose rather than the scale. Projects that depended on that functionality can use Legacy mode to revert to the old method.
• Changed Grab Interactable default Movement Type from Kinematic to Instantaneous.
• Changed Grab Interactable default values for damping and scale so Velocity Tracking moves more similar to the other Movement Type values, making the distinguishing feature instead be how it collides with other Colliders without Rigidbody components. Changed velocityDamping from 0.4 to 1, angularVelocityDamping from 0.4 to 1, and angularVelocityScale from 0.95 to 1.
• Changed Socket Interactor override of the Movement Type of Interactables from Kinematic to Instantaneous.
• Changed XR Controller so it does not modify the Transform position, rotation, or scale of the instantiated model prefab upon startup instead of resetting those values.
• Changed Controller Interactors to let the XR Controller be on a parent GameObject.
• Changed so XR Interaction Debugger's Input Devices view is off by default.
• Changed Tracked Device Graphic Raycaster to fallback to using Camera.main when the Canvas does not have an Event Camera set.
• Changed XR Rig property for the Tracking Origin Mode to only contain supported modes. A value of Not Specified will use the default mode of the XR device.
• Changed GameObject > XR menu to only have a single XR Rig rather than separate menu items for Room-Scale and Stationary. Change the Tracking Origin Mode property on the created XR Rig to Floor or Device, respectively, for the same behavior as before.

Deprecated

• Deprecated XRBaseController.modelTransform due to being renamed to XRBaseController.modelParent.
• Deprecated XRRig.trackingOriginMode due to being replaced with an enum type that only contains supported modes. Use XRRig.requestedTrackingOriginMode and XRRig.currentTrackingOriginMode instead.

Fixed

• Fixed Interaction Manager throwing exception InvalidOperationException: Collection was modified; enumeration operation may not execute. when an Interactor or Interactable was registered or unregistered during processing and events.
• Fixed Windows Mixed Reality controllers having an incorrect pose when using the Default Input Actions sample. The Position and Rotation input actions will try to bind to pointerPosition and pointerRotation, and fallback to devicePosition and deviceRotation. If the sample has already been imported into your project, you will need to import again to get the update.
• Fixed Input System actions such as Select not being recognized as pressed in ActionBasedController when it was bound to an Axis control (for example '/grip') rather than a Button control (for example '/gripPressed').
• Fixed XR Interaction Debugger to display Interactors and Interactables from multiple Interaction Managers.
• Fixed XR Interaction Debugger having overlapping text when an Interactor was hovering over multiple Interactables.
• Fixed Tree View panels in the XR Interaction Debugger to be collapsible.
• Fixed TestFixture classes in the test assembly to be internal instead of public.
• Fixed Grab Interactable to use scaled time for easing and smoothing instead of unscaled time.
• Fixed Direct and Socket Interactor not being able to interact with an Interactable with multiple Colliders when any of the Colliders leaves the trigger instead of only when all of them leave. (1325375)
• Fixed Direct and Socket Interactor not being able to interact with an Interactable when either were registered after the trigger collision occurred.
• Fixed XRSocketInteractor to include the select target in its list of valid targets returned by GetValidTargets.
• Fixed XRBaseController so it applies the controller state during Before Render even when Input Tracking is disabled.
• Fixed missing namespace of InputHelpers to be UnityEngine.XR.Interaction.Toolkit.

[1.0.0-pre.3] - 2021-03-18

Added

• Added ability for serialized fields added in derived behaviors to automatically appear in the Inspector. Users will no longer need to create a custom Editor to be able to see those fields in the Inspector. See Extending the XR Interaction Toolkit in the manual for details about customizing how they are drawn.
• Added support for EnhancedTouch from the Input System for AR gesture classes. This means AR interaction is functional when the Active Input Handling project setting is set to Input System Package (New).
• Added registration events to XRBaseInteractable and XRBaseInteractor which work like those in XRInteractionManager but for just that object.
• Added new methods in ARPlacementInteractable to divide the logic in OnEndManipulation into TryGetPlacementPose, PlaceObject, and OnObjectPlaced.
• Added XRRayInteractor.hitClosestOnly property to limit the number of valid targets. Enable this to make only the closest Interactable receive hover events rather than all Interactables in the full length of the ray cast.
• Added new methods in XRRayInteractor for getting information about UI hits, and made more methods virtual or public.
• Added several properties to Grab Interactable (Damping and Scale) to allow for tweaking the velocity and angular velocity when the Movement Type is Velocity Tracking. These values can be adjusted to reduce oscillation and latency from the Interactor.

Changed

• Changed script execution order so LocomotionProvider occurs before Interactors are processed, fixing Ray Interactor from casting with stale controller poses when moving or turning the rig and causing visual flicker of the line.
• Changed script execution order so XRUIInputModule processing occurs after LocomotionProvider and before Interactors are processed to fix the frame delay with UI hits due to using stale ray cast rays. XRUIInputModule.Process now does nothing, override XRUIInputModule.DoProcess which is called directly from Update.
• Changed XRUIInputModule.DoProcess from abstract to virtual. Overriding methods in derived classes should call base.DoProcess to ensure IUpdateSelectedHandler event sending occurs as before.
• Changed Ray Interactor's Reference Frame property to use global up as a fallback when not set instead of the Interactor's up.
• Changed Ray Interactor Projectile Curve to end at ground height rather than controller height. Additional Ground Height and Additional Flight Time properties can be adjusted to control how long the curve travels, but this change means the curve will be longer than it was in previous versions.
• Changed TrackedDeviceGraphicRaycaster to ignore Trigger Colliders by default when checking for 3D occlusion. Added raycastTriggerInteraction property to control this.
• Changed XRBaseInteractor.allowHover and XRBaseInteractor.allowSelect to retain their value instead of getting changed to true during OnEnable. Their initial values are unchanged, remaining true.
• Changed some AR behaviors to be more configurable rather than using some hardcoded values or requiring using MainCamera. AR Placement Interactable and AR Translation Interactable must now specify a Fallback Layer Mask to support non-trackables instead of always using Layer 9.
• Changed IUIInteractor to not inherit from ILineRenderable.

Deprecated

• Deprecated XRBaseInteractor.enableInteractions, use XRBaseInteractor.allowHover and XRBaseInteractor.allowSelect instead.

Removed

• Removed several MonoBehaviour message functions in AR behaviors to use ProcessInteractable and ProcessInteractor instead.

Fixed

• Fixed issue where the end of a Projectile or Bezier Curve lags behind and appears bent when the controller is moved too fast. (1291060)
• Fixed Ray Interactor interacting with Interactables that are behind UI. (1312217)
• Fixed XRRayInteractor.hoverToSelect not being functional. (1301630)
• Fixed Ray Interactor not allowing for valid targets behind an Interactable with multiple Collider objects when the ray hits more than one of those Colliders.
• Fixed Ray Interactor performance to only perform ray casts once per frame instead of each time GetValidTargets is called by doing it during ProcessInteractor instead.
• Fixed exception in XRInteractorLineVisual when changing the Sample Frequency or Line Type of a Ray Interactor.
• Fixed Ray Interactor anchor control rotation when the Rig plane was not up. Added a property anchorRotateReferenceFrame to control the rotation axis.
• Fixed Reference Frame missing from the Ray Interactor Inspector when the Line Type was Bezier Curve.
• Fixed mouse scroll amount being too large in XRUIInputModule when using Input System.
• Fixed Scrollbar initially scrolling to incorrect position at XR pointer down when using TrackedDeviceGraphicRaycaster, which was caused by RaycastResult.screenPosition never being set.
• Fixed GestureRecognizer skipping updating some gestures during the same frame when another gesture finished.
• Fixed namespace of several Editor classes to be in UnityEditor.XR.Interaction.Toolkit instead of UnityEngine.XR.Interaction.Toolkit.
• Fixed default value of Blocking Mask on Tracked Device Graphic Raycaster to be Everything (was skipping Layer 31).

[1.0.0-pre.2] - 2021-01-20

Added

• Added registration events to XRInteractionManager and OnRegistered/OnUnregistered methods to XRBaseInteractable and XRBaseInteractor.
• Added and improved XML documentation comments and tooltips.
• Added warnings to XR Controller (Action-based) when referenced Input Actions have not been enabled.
• Added warning to Tracked Device Graphic Raycaster when the Event Camera is not set on the World Space Canvas.

Changed

• Changed XRBaseInteractable and XRBaseInteractor to no longer register with XRInteractionManager in Awake and instead register and unregister in OnEnable and OnDisable, respectively.

• Changed the signature of all interaction event methods (e.g. OnSelectEntering) to take event data through a class argument rather than being passed the XRBaseInteractable or XRBaseInteractor directly. This was done to allow for additional related data to be provided by the Interaction Manager without requiring users to handle additional methods. This also makes it easier to handle the case when the selection or hover is canceled (due to either the Interactor or Interactable being unregistered as a result of being disabled or destroyed) without needing to duplicate code in an OnSelectCanceling and OnSelectCanceled.

  Old Signature	New Signature
  OnHoverEnter*(XRBaseInteractor interactor) -and- OnHoverEnter*(XRBaseInteractable interactable)	OnHoverEnter*(HoverEnterEventArgs args)

      protected override void OnSelectEntering(SelectEnterEventArgs args)
      {
          base.OnSelectEntering(args);
          var interactor = args.interactor;
          // Do something with interactor
      }
  }
  
  // Example behavior that is the target of an Interactable Event set in the Inspector with a Dynamic binding.
  public class ExampleListener : MonoBehaviour
  {
      // Old code -- delete after migrating to new method signature and fixing reference in Inspector
      public void OnSelectEntered(XRBaseInteractor interactor)
      {
          // Do something with interactor
      }
  
      // New code
      public void OnSelectEntered(SelectEnterEventArgs args)
      {
          var interactor = args.interactor;
          // Do something with interactor
      }
  }
  

• Changed which methods are called by the Interaction Manager when either the Interactor or Interactable is unregistered. Previously XRBaseInteractable had OnSelectCanceling and OnSelectCanceled called on select cancel, and OnSelectExiting and OnSelectExited called when not canceled. This has been combined into OnSelectExiting(SelectExitEventArgs) and OnSelectExited(SelectExitEventArgs) and the isCanceled property is used to distinguish as needed. The Select Exited event in the Inspector is invoked in either case.

  public class ExampleInteractable : XRBaseInteractable
  {
      protected override void OnSelectExiting(SelectExitEventArgs args)
      {
          base.OnSelectExiting(args);
          // Do something common to both.
          if (args.isCanceled)
              // Do something when canceled only.
          else
              // Do something when not canceled.
      }
  
  }
  

• Changed many custom Editors to also apply to child classes so they inherit the custom layout of the Inspector. If your derived class adds a SerializeField or public field, you will need to create a custom Editor to be able to see those fields in the Inspector. For Interactor and Interactable classes, you will typically only need to override the DrawProperties method in XRBaseInteractorEditor or XRBaseInteractableEditor rather than the entire OnInspectorGUI. See Extending the XR Interaction Toolkit in the manual for a code example.
• Changed XRInteractionManager.SelectCancel to call OnSelectExiting and OnSelectExited on both the XRBaseInteractable and XRBaseInteractor in a similar interleaved order to other interaction state changes and when either is unregistered.
• Changed order of XRInteractionManager.UnregisterInteractor to first cancel the select state before canceling hover state for consistency with the normal update loop which exits select before exiting hover.
• Changed XRBaseInteractor.StartManualInteraction and XRBaseInteractor.EndManualInteraction to go through XRInteractionManager rather than bypassing constraints and events on the Interactable.
• Changed the GameObject > XR > Grab Interactable menu item to create a visible cube and use a Box Collider so that it is easier to use.
• Renamed LocomotionProvider.startLocomotion to LocomotionProvider.beginLocomotion for consistency with method name.

Fixed

• Fixed Direct Interactor and Socket Interactor causing exceptions when a valid target was unregistered, such as from being destroyed.
• Fixed Ray Interactor clearing custom direction when initializing (fixed initialization of the Original Attach Transform so it copies values from the Attach Transform instead of setting position and rotation values to defaults). (1291523)
• Fixed Socket Interactor so only an enabled Renderer is drawn while drawing meshes for hovered Interactables.
• Fixed Grab Interactable to respect Interaction Layer Mask for whether it can be hovered by an Interactor instead of always allowing it.
• Fixed Grab Interactable so it restores the Rigidbody's drag and angular drag values on drop.
• Fixed mouse input not working with Unity UI when Active Input Handling was set to Input System Package.
• Fixed issue where Interactables in AR were translated at the height of the highest plane regardless of where the ray is cast.
• Fixed so steps to setup camera in XRRig only occurs in Play mode in the Editor.
• Fixed file names of .asmdef files to match assembly name.
• Fixed broken links for the help button (?) in the Inspector so it opens Scripting API documentation for each behavior in the package. (1291475)
• Fixed XR Rig so it handles the Tracking Origin Mode changing on the device.
• Fixed XR Controller so it only sets position and rotation while the controller device is being tracked instead of resetting to the origin (such as from the device disconnecting or opening a system menu).
