TouchHandGrabInteractable Class

Extends PointerInteractable< TouchHandGrabInteractor, TouchHandGrabInteractable >

Provides a hand-specific, collisions-based, grab interaction model (distinct from HandGrab.HandGrabInteractor's spatial hueristic approach) where selection begins when finger tips overlap with an associated interactable.

This interaction mode simulates the physicality of grabbing a real-world object with the fingertips.

Fields

ColliderGroup ColliderGroup[Get]

Retrieves the Interaction.ColliderGroup associated with this interactable.

TouchHandGrabInteractables can require multiple Colliders in order to effectively characterize the grabbable shape, particularly for complex models, so a group is used to aggregate them.

Protected Functions

override void Start ( )

Member Functions

void InjectAllTouchHandGrabInteractable

( Collider boundsCollider,

List< Collider > colliders )

Convenience method combining InjectBoundsCollider(Collider) and InjectColliders(List<Collider>).

This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.

void InjectColliders

( List< Collider > colliders )

Sets the list of Unity Colliders to be made into an Interaction.ColliderGroup of a dynamically instantiated TouchHandGrabInteractable.

Because ColliderGroup is instantiated from this list in Unity's Start() method, this must be called before the MonoBehaviour lifecycle initializes this instance; otherwise, the provided colliders will be ignored. This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
