Interface 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.
Namespace: UnityEngine.XR.Interaction.Toolkit.Filtering
Syntax
public interface IXRTargetEvaluatorLinkableMethods
OnLink(IXRInteractor)
Called by the Target Filter when it links to the given Interactor.
This is also called after the evaluator's Awake() for each already linked Interactor.
Use this only for code initialization for the given Interactor.
Declaration
void OnLink(IXRInteractor interactor)Parameters
| Type | Name | Description |
|---|---|---|
| IXRInteractor | interactor | The Interactor being linked to the filter. |
Remarks
This is called even if the evaluator is disabled. You can check if the evaluator is enabled using the
enabled property.
You should not update the linked interactor list or the evaluator list in the filter, nor should you
disable or enable evaluators. This can lead to out-of-order calls to OnLink(IXRInteractor) and OnUnlink(IXRInteractor).
See Also
OnUnlink(IXRInteractor)
Called by the Target Filter when it unlinks from the given Interactor.
This is also called before the evaluator's OnDispose() for each linked Interactor.
Use this for any code cleanup for the given Interactor.
Declaration
void OnUnlink(IXRInteractor interactor)Parameters
| Type | Name | Description |
|---|---|---|
| IXRInteractor | interactor | The Interactor being unlinked from this filter. |
Remarks
This is called even if the evaluator is disabled. You can check if the evaluator is enabled using the
enabled property.
You should not update the linked interactor list or the evaluator list in the filter, nor should you
disable or enable evaluators. This can lead to out-of-order calls to OnLink(IXRInteractor) and OnUnlink(IXRInteractor).
