====== ECBehaviorInteraction ======

Behavior element behavior adding storing supported interactions.

====== Instance Counts ======

This behavior can be used only once on an element.

====== Element Class Properties ======

This behavior adds no element class properties.

====== Events ======

This behavior has no event

====== Behavior Tree Actions ======

This behavior adds no behavior tree actions.

====== Behavior Tree Conditions ======

This behavior adds no behavior tree conditions.

====== State Machine Actions ======

This behavior adds no state machine actions.

====== State Machine Conditions ======

This behavior adds no state machine conditions.

====== State Machine Events ======

This behavior does not send state machine events.

====== Required Behaviors ======

This behavior requires no other behaviors.

====== Optional Behaviors ======

This behavior supports no optional behaviors.

====== Persistency ======

This behavior does not required element class to be persistable (setPersistable)

====== API Documentation ======

#@LinkApiDocDEDS2_HTML~classDragengine_1_1Scenery_1_1ECBehaviorInteraction.html,ECBehaviorInteraction~@#.

Since DragonScript Module Version ''1.26''

====== Use Cases ======

  * Allow behaviors to add interactions usable by player/actor conversation scripts, behaviors trees and state machines

====== Element Class Example ======

This example defines an element which contains a interaction. The "MyBehaviorWithInteraction" class has to add an instance of a class implementing ECBehaviorInteraction.Interaction to "interaction". This can be for example an interaction named "frob" which triggers for a ECBehaviorTwoStateAnimated behavior.

<code>
class MyElement extends BehaviorElementClass
  public var ECBehaviorInteraction interaction
  public var MyBehaviorWithInteraction myBehavior
  func new()
    interaction = ECBehaviorInteraction.new(this)
    myBehavior = MyBehaviorWithInteraction.new(this, interaction)
  end
end
</code>

====== Behavior Factory ======

Using element class supporting adding behaviors the behavior can be added like this:
<code xml>
<?xml version='1.0' encoding='UTF-8'?>
<elementClass name='MyClass' class='GenericBehaviorElement'>
  <behavior type='ECBehaviorInteraction'/>
</elementClass>
</code>
