This struct indicates which fingers should be taken in count for performing an interaction (for example, in HandGrab.HandGrabInteractor).
All required fingers must be in use in order to start the interaction while any of the optional fingers is needed. For finishing the action it supports either releasing all fingers or any of them.
Returns the FingerUnselectMode for this instance, which dictates whether the grab defined by this rule ends when any of its required fingers release, or when all of them do.
Properties
bool SelectsWithOptionals[Get]
This property checks whether this grab can be performed using only fingers marked FingerRequirement.Optional.
The property is true only if no fingers are marked as FingerRequirement.Required, false otherwise.
Standard definition for "palm grab": requires the middle three fingers to begin a grab, allowing that grab to persist as long as any finger continues grabbing.
Standard definition for "pinch grab": allows grabbing to begin when any of the first three fingers (thumb, index, middle) grabs, persisting the grab as long as any of those three is grabbing, and ignoring the last two fingers.
Standard definition for "full grab": requires all five fingers to begin a grab, allowing that grab to persist as long as any finger continues grabbing.
Member Functions
