Class XRDirectInteractor

Interactor used for directly interacting with interactables that are touching. This is handled via trigger volumes that update the current set of valid targets for this interactor. This component must have a collision volume that is set to be a trigger to work.

Properties

improveAccuracyWithSphereCollider

When a Sphere Collider component is the only collider on this interactor, and no Rigidbody component is attached, the interactor will use Burst compiler optimizations and sphere casts instead of relying on physics trigger events to evaluate direct interactions when this property is enabled. This also improves inter-frame accuracy and reliability.

Declaration
public bool improveAccuracyWithSphereCollider { get; set; }
Property Value
Type Description
bool
Remarks

Cannot change this value at runtime after Awake. Enabling this property can improve inter-frame reliability during fast motion when the requirements for optimization are met by running on each Update instead of Fixed Update and using a sphere cast to determine valid targets. Disable to force the use of trigger events, such as the OnTriggerStay and FixedUpdate methods.

See Also

physicsLayerMask

Physics layer mask used for limiting direct interactor overlaps when using the improveAccuracyWithSphereCollider option.

Declaration
public LayerMask physicsLayerMask { get; set; }
Property Value
Type Description
LayerMask

physicsTriggerInteraction

Determines whether the direct interactor sphere overlap will hit triggers when using the improveAccuracyWithSphereCollider option.

Declaration
public QueryTriggerInteraction physicsTriggerInteraction { get; set; }
Property Value
Type Description
QueryTriggerInteraction
Remarks

When set to UseGlobal, the value of Queries Hit Triggers (queriesHitTriggers) in Edit > Project Settings > Physics will be used.

unsortedValidTargets

The set of Interactables that this Interactor could possibly interact with this frame. This list is not sorted by priority.

Declaration
protected List<IXRInteractable> unsortedValidTargets { get; }
Property Value
Type Description
List<IXRInteractable>
See Also

usingSphereColliderAccuracyImprovement

Whether the requirements were successfully met to use the alternate improved collider accuracy code path.

Declaration
public bool usingSphereColliderAccuracyImprovement { get; }
Property Value
Type Description
bool
Remarks

The requirements are a single Sphere Collider component and no Rigidbody component on this GameObject.

Overrides

CanHover(IXRHoverInteractable)

Determines if the Interactable is valid for hover this frame.

Declaration
public override bool CanHover(IXRHoverInteractable interactable)
Parameters
Type Name Description
IXRHoverInteractable interactable

Interactable to check.
Returns
Type Description
bool

Returns true if the Interactable can be hovered over this frame.
Overrides

CanSelect(IXRSelectInteractable)

Determines if the Interactable is valid for selection this frame.

Declaration
public override bool CanSelect(IXRSelectInteractable interactable)
Parameters
Type Name Description
IXRSelectInteractable interactable

Interactable to check.
Returns
Type Description
bool

Returns true if the Interactable can be selected this frame.

GetValidTargets(List<IXRInteractable>)

Retrieve the list of Interactables that this Interactor could possibly interact with this frame. This list is sorted by priority (with highest priority first).

Declaration
public override void GetValidTargets(List<IXRInteractable> targets)
Parameters
Type Name Description
List<IXRInteractable> targets

The results list to populate with Interactables that are valid for selection or hover.
Overrides
Remarks

When implementing this method, Unity expects you to clear targets before adding to it.

OnDisable()

See MonoBehaviour.

Declaration
protected override void OnDisable()
Overrides

OnEnable()

See MonoBehaviour.

Declaration
protected override void OnEnable()
Overrides

OnRegistered(InteractorRegisteredEventArgs)

The XRInteractionManager calls this method when this Interactor is registered with it.

Declaration
protected override void OnRegistered(InteractorRegisteredEventArgs args)
Parameters
Type Name Description
InteractorRegisteredEventArgs args

Event data containing the Interaction Manager that registered this Interactor.
Overrides
Remarks

args is only valid during this method call, do not hold a reference to it.

OnTriggerEnter(Collider)

See MonoBehaviour.

Declaration
protected void OnTriggerEnter(Collider other)
Parameters
Type Name Description
Collider other

The other Collider involved in this collision.

OnTriggerExit(Collider)

See MonoBehaviour.

Declaration
protected void OnTriggerExit(Collider other)
Parameters
Type Name Description
Collider other

The other Collider involved in this collision.

OnTriggerStay(Collider)

See MonoBehaviour.

Declaration
protected void OnTriggerStay(Collider other)
Parameters
Type Name Description
Collider other

The other Collider involved in this collision.

OnUnregistered(InteractorUnregisteredEventArgs)

The XRInteractionManager calls this method when this Interactor is unregistered from it.

Declaration
protected override void OnUnregistered(InteractorUnregisteredEventArgs args)
Parameters
Type Name Description
InteractorUnregisteredEventArgs args

Event data containing the Interaction Manager that unregistered this Interactor.
Overrides
Remarks

args is only valid during this method call, do not hold a reference to it.

PreprocessInteractor(UpdatePhase)

The XRInteractionManager or containing IXRInteractionGroup calls this method to update the Interactor before interaction events occur. Interactors should use this method to do tasks like determine their valid targets.

Declaration
public override void PreprocessInteractor(XRInteractionUpdateOrder.UpdatePhase updatePhase)
Parameters
Type Name Description
XRInteractionUpdateOrder.UpdatePhase updatePhase

The update phase this is called during.
Overrides
Remarks

Please see the XRInteractionManager and XRInteractionUpdateOrder.UpdatePhase documentation for more details on update order.

See Also

ProcessInteractor(UpdatePhase)

The XRInteractionManager or containing IXRInteractionGroup calls this method to update the Interactor after interaction events occur.

Declaration
public override void ProcessInteractor(XRInteractionUpdateOrder.UpdatePhase updatePhase)
Parameters
Type Name Description
XRInteractionUpdateOrder.UpdatePhase updatePhase

The update phase this is called during.
Overrides
Remarks

Please see the XRInteractionManager and XRInteractionUpdateOrder.UpdatePhase documentation for more details on update order.
