Interface IXRInteractionOverrideGroup

An interface that represents an Interaction Group component that is capable of overriding the interaction of the activeInteractor when another interactor tries to select any of the interactables being hovered or selected. An interactor can only override interaction when it is or is contained within a Group member that is configured as a possible override for the active Group member.

Syntax

public interface IXRInteractionOverrideGroup : IXRInteractionGroup

Methods

AddInteractionOverrideForGroupMember(IXRGroupMember, IXRGroupMember)

Adds overrideGroupMember as a possible interaction override for sourceGroupMember.

Declaration

void AddInteractionOverrideForGroupMember(IXRGroupMember sourceGroupMember, IXRGroupMember overrideGroupMember)

Parameters

Type	Name	Description
IXRGroupMember	sourceGroupMember	The Group member whose interaction can be potentially overridden by overrideGroupMember.
IXRGroupMember	overrideGroupMember	The Group member to add as a possible interaction override.

Remarks

Both members must be registered with the Group. Additionally, overrideGroupMember must implement either IXRSelectInteractor or IXRInteractionOverrideGroup. This method must not create a loop in the chain of overrides for sourceGroupMember. Use the implementation of GroupMemberIsPartOfOverrideChain(IXRGroupMember, IXRGroupMember) to ensure there is no loop before adding override.

IXRGroupMember

ClearInteractionOverridesForGroupMember(IXRGroupMember)

Clears the set of possible interaction overrides for sourceGroupMember.

Declaration

bool ClearInteractionOverridesForGroupMember(IXRGroupMember sourceGroupMember)

Parameters

Type	Name	Description
IXRGroupMember	sourceGroupMember	The Group member whose interaction can no longer be overridden.

Returns

Type	Description
bool	Returns true if there is a set of overrides for sourceGroupMember. Otherwise, returns false.

Remarks

sourceGroupMember must be registered with the Group.

GetInteractionOverridesForGroupMember(IXRGroupMember, HashSet<IXRGroupMember>)

Returns all members in the set of possible interaction overrides for sourceGroupMember into set results.

Declaration

void GetInteractionOverridesForGroupMember(IXRGroupMember sourceGroupMember, HashSet<IXRGroupMember> results)

Parameters

Type	Name	Description
IXRGroupMember	sourceGroupMember	The Group member whose overrides to get.
HashSet<IXRGroupMember>	results	Set to receive override Group members.

Remarks

sourceGroupMember must be registered with the Group. This method populates the set with the Group members at the time the method is called. It is not a live view, meaning override Group members added or removed afterward will not be reflected in the results of this method. Clears results before adding to it.

IXRGroupMember

GroupMemberIsPartOfOverrideChain(IXRGroupMember, IXRGroupMember)

Checks whether potentialOverrideGroupMember is either the same as sourceGroupMember or part of a chain of its override Group members and their overrides.

Declaration

bool GroupMemberIsPartOfOverrideChain(IXRGroupMember sourceGroupMember, IXRGroupMember potentialOverrideGroupMember)

Parameters

Type	Name	Description
IXRGroupMember	sourceGroupMember	The source Group member for the potential chain of override members.
IXRGroupMember	potentialOverrideGroupMember	The Group member to check for as part of a chain of overrides.

Returns

Type	Description
bool	Returns true if potentialOverrideGroupMember is either the same as sourceGroupMember or part of a chain of its override Group members and their overrides. Otherwise, returns false.

IXRGroupMember

RemoveInteractionOverrideForGroupMember(IXRGroupMember, IXRGroupMember)

Removes overrideGroupMember as a possible interaction override for sourceGroupMember.

Declaration

bool RemoveInteractionOverrideForGroupMember(IXRGroupMember sourceGroupMember, IXRGroupMember overrideGroupMember)

Parameters

Type	Name	Description
IXRGroupMember	sourceGroupMember	The Group member whose interaction can no longer be overridden by overrideGroupMember.
IXRGroupMember	overrideGroupMember	The Group member to remove as a possible interaction override.

Returns

Type	Description
bool	Returns true if overrideGroupMember was removed from the set of potential overrides for sourceGroupMember. Otherwise, returns false if overrideGroupMember was not part of the set.

Remarks

sourceGroupMember must be registered with the Group.

IXRGroupMember

ShouldAnyMemberOverrideInteraction(IXRInteractor, out IXRSelectInteractor)

Checks whether any member of the Group should override the interactions of interactingInteractor. An interactor should only override if it is capable of selecting any interactable that interactingInteractor is interacting with. If multiple Group members are capable of overriding, only the highest priority one should override.

Declaration

bool ShouldAnyMemberOverrideInteraction(IXRInteractor interactingInteractor, out IXRSelectInteractor overridingInteractor)

Parameters

Type	Name	Description
IXRInteractor	interactingInteractor	The interactor that is interacting with an interactable.
IXRSelectInteractor	overridingInteractor	The interactor that should override interaction.

Returns

Type	Description
bool	Returns true if any member of the Group should override the interactions of interactingInteractor. Otherwise, returns false.

Remarks

The implementation of this method should call this method on each Group member that is an IXRInteractionOverrideGroup.

IXRGroupMember

ShouldOverrideActiveInteraction(out IXRSelectInteractor)

Checks whether the Group should end the interactions of the activeInteractor and instead prioritize an override interactor for interaction. An interactor should only override if it exists in the set of override Group members for the active member and is capable of selecting any interactable that activeInteractor is interacting with. If multiple Group members are capable of overriding, only the highest priority one should override.

Declaration

bool ShouldOverrideActiveInteraction(out IXRSelectInteractor overridingInteractor)

Parameters

Type	Name	Description
IXRSelectInteractor	overridingInteractor	The interactor that should override interaction.

Returns

Type	Description
bool	Returns true if the Group should end the interactions of the activeInteractor and instead prioritize an override interactor for interaction. Otherwise, returns false.

Remarks

The implementation of UpdateGroupMemberInteractions(IXRInteractor, out IXRInteractor) should call this method at the start to determine whether overridingInteractor should override the pre-prioritized interactor. The implementation of this method should call ShouldAnyMemberOverrideInteraction(IXRInteractor, out IXRSelectInteractor) on each override Group member that is an IXRInteractionOverrideGroup.
