Detailed Description
Behavior element behavior adding support to grab an ECBehaviorGrabSpot.
- Version
- 1.9
Grab spots are typically used for physics interaction like VR hand use but can be used also with mouse interaction. The actual grabbing interaction, exact grab location and orientation as well as attaching logic is handled by other behaviors using listening. This behavior also tracks if what grab spot an actor is grabbing. Hence at most one grab spot can be grabbed by this behavior at each time.
Elements able to be grabbed have to use the ECBehaviorGrabSpot behavior. Both the grab spot and the grabber have to persist the other behavior. During restoring no notifications are triggered this way.
Do detect grab spots a touch sensor is added with a default sphere shape. By default the touch sensor is disabled and has to be enabled if the game logic allows grabbing. The collision filter category is set to BaseGameApp.CollisionFilterBit.trigger and the collision filter mask is set to BaseGameApp.CollisionFilterBit.dynamic.
Element class properties have the prefix "grabber{(id)}.".
This behavior uses no other behaviors.
This behavior does not require the element class to be persistable (setPersistable).
The documentation for this class was generated from the following file:
