Namespace UnityEngine.XR.Interaction.Toolkit.Filtering

Classes

PokeThresholdData

The settings used to fine tune the vector and offsets which dictate how the poke interaction will be evaluated.

PokeThresholdDatum

ScriptableObject container class that holds a PokeThresholdData value.

PokeThresholdDatumProperty

Serializable container class that holds a poke threshold value or container asset reference.

TouchscreenHoverFilter

Hover filter that checks if the screen is being touched and doing a selecting gesture. Can be used with the ray interactor to prevent hover interactions when the screen is not being touched.

XRAngleGazeEvaluator

Evaluates the angle between the Gaze Transform's forward direction and the vector to the target Interactable. The target Interactable with the smallest angle will receive the highest normalized score.

XRBaseTargetFilter

Abstract base class from which all Target Filter behaviours derive. Instances of this class can be assigned to an XRBaseInteractor using the Inspector by setting the Starting Target Filter (startingTargetFilter). This serves as a serializable reference instead of using targetFilter which is not serialized.

XRDistanceEvaluator

Evaluates the Interactor distance from the target Interactable. Targets close to the Interactor will receive a highest score and targets far way will receive a lower score.

XRHoverFilterDelegate

A hover filter that forwards its processing to a delegate (delegateToProcess). Useful to create custom filters by code without needing to create new classes.

XRInteractionStrengthFilterDelegate

An interaction strength filter that forwards its processing to a delegate (delegateToProcess). Useful to create custom filters by code without needing to create new classes.

XRLastSelectedEvaluator

The last selected target Interactable will receive the highest normalized score. In the moment that an Interactable is selected by any of the linked Interactors, it'll have the highest normalized score of 1. Its normalized score will linearly decrease with time until the score reaches 0 after maxTime seconds.

XRPokeFilter

Filter component that allows for basic poke functionality and to define constraints for when the interactable will be selected.

XRSelectFilterDelegate

A select filter that forwards its processing to a delegate (delegateToProcess). Useful to create custom filters by code without needing to create new classes.

XRTargetEvaluator

Abstract base class from which all Target Evaluators derive. This class evaluates the intention to interact with an Interactable by calculating a score (a float value). Used by the XRTargetFilter behavior which allows the list of valid targets returned by an Interactor to be customized as determined by these evaluators.

XRTargetFilter

Target Filter that uses a list of evaluator objects to filter Interactable targets (candidates) returned by the Interactor each frame. You can edit the evaluator list and the evaluators properties in the Inspector.

Structs

PokeStateData

Holds information used for poke interaction affordances.

Interfaces

IMultiPokeStateDataProvider

Multiplexed version of IPokeStateDataProvider that allows for multiple targets to be tracked with their own bindable poke state data.

IPokeStateDataProvider

This provider interface allows a source component to populate PokeStateData upon request to a component that is bound to the pokeStateData bindable variable that provides state data about a poke interaction. Typically this is needed by an affordance listener for poke.

IXRFilterList<T>

A list of items.

IXRHoverFilter

Instances that implement this interface are called hover filters. Hover filters process additional validation checks after the base class hover validation checks are processed. Add a hover filter to the following objects to extend its hover validations:

• XRInteractionManager: to add a global hover filter used to validate all hover interactions in the manager.
• XRBaseInteractor: to add an Interactor hover filter used to validate the hover interactions in the Interactor.
• XRBaseInteractable: to add an Interactable hover filter used to validate the hover interactions in the Interactable.

IXRInteractionStrengthFilter

Instances that implement this interface are called interaction strength filters. Interaction strength filters are used to adjust or set the interaction strength between an Interactor and Interactable.

IXRPokeFilter

Instances that implement this interface are called XR Poke filters. Poke filters are used to customize basic poke functionality and to define constraints for when the interactable will be selected.

IXRSelectFilter

Instances that implement this interface are called select filters. Select filters process additional validation checks after the base class select validation checks are processed. Add a select filter to the following objects to extend its select validations:

• XRInteractionManager: to add a global select filter used to validate all select interactions in the manager.
• XRBaseInteractor: to add an Interactor select filter used to validate the select interactions in the Interactor.
• XRBaseInteractable: to add an Interactable select filter used to validate the select interactions in the Interactable.

IXRTargetEvaluatorLinkable

An interface that an XRTargetFilter can implement to receive calls whenever an Interactor links to or unlinks from its filter.
Implement this interface if the evaluator needs to subscribe to events or cache data from the linked Interactors.

IXRTargetFilter

An interface responsible to filter a list of Interactable targets (candidates) for interaction with a linked Interactor.

Enums

PokeAxis

Represents the poke evaluation axis used.
