Behavior element behavior adding support to track if VR hands point at element.

This behavior tracks if hand controllers are pointing at the element. If hand controllers start pointing at the element they are added to the list and listeners are notified. If the hand controllers stop pointing at the element they are removed from the list and listeners are notified. The behavior itself is passive. It requires to be triggered by the hand controllers elements. The ECBehaviorVRHandPointAt behavior provides this functionality.

This behavior can be used only once on an element. The behavior always has identifier empty string.

Element class properties have the prefix vrHandPointedAt..

This behavior defines no element class properties.

This behavior does not required other behaviors to be present.

This behavior does not support optional behaviors.

This behavior does support element class to be persistable (setPersistable).

Saves the list of ECBehaviorVRHandPointAt pointing at the element.

This behavior supports adding listeners. These events can be received:

ECBehaviorVRHandPointAt starts pointing at object. Event contains ECBehaviorVRHandPointAt pointing at object.

ECBehaviorVRHandPointAt stops pointing at object. Event contains ECBehaviorVRHandPointAt no more pointing at object.

ECBehaviorVRHandPointedAt.

Since DragonScript Module Version 1.7

• Show outline and interact prompts if player points at object.
• For NPCs to react to player (or other actors) pointing at them (for example looking back at player).
• Show target information if player aims at objects.

class ExampleElementClass extends BehaviorElementClass
   public var ECBehaviorVRHandPointedAt vrHandPointedAt
   
   public func new() super("ExampleElement")
     // Add pointed at behavior. By itself this does nothing yet. Add listeners to the
     // behavior to react to pointing-at changes. This is typically done by other
     // behaviors to provide their functionality
     vrHandPointedAt = ECBehaviorVRHandPointedAt.new(this)
   end
end
