====== ECBehaviorAttachable ======

Behavior element behavior adding support to be attached to an [[behavior_attachslot|ECBehaviorAttachSlot]].

While [[behavior_attachtoparent|ECBehaviorAttachToParent]] behavior allows to attach objects by using the IGDE World Editor the ECBehaviorAttachable behavior allows to attach objects at runtime into attachment slots provided by [[behavior_attachslot|ECBehaviorAttachSlot]].

This behavior knows how to attach to [[behavior_attachslot|ECBehaviorAttachSlot]] containing an [[behavior_collider|ECBehaviorCollider]].

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

This behavior can be used only once on an element.

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

Element class properties have the prefix ''attachable.'' .

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

This behavior has these events:

===== attachableAttached =====

Attachable has been attached to slot.

===== attachableDetached =====

Attachable has been removed from slot.

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

  * [[behavior_collider|ECBehaviorCollider]]

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

This behavior does not support optional behaviors.

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

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

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

#@LinkApiDocDEDS2_HTML~classDragengine_1_1Scenery_1_1ECBehaviorAttachable.html,ECBehaviorAttachable~@#.

Since DragonScript Module Version ''1.0''

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

  * Allow element to be attached to [[behavior_attachslot|ECBehaviorAttachSlot]] present on other elements.

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

This example defines an element which can be attached to [[behavior_attachslot|ECBehaviorAttachSlot]].

<code>
class MyElement extends BehaviorElementClass
  public var ECBehaviorComponent component
  public var ECBehaviorCollider collider
  public var ECBehaviorAttachable attachable
  func new()
    component = ECBehaviorComponent.new(this, null)
    collider = ECBehaviorCollider.new(this, component)
    attachable = ECBehaviorAttachable.new(this, collider)
  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='ECBehaviorComponent'/>
  <behavior type='ECBehaviorCollider'/>
  
  <behavior type='ECBehaviorAttachable'>
    <!-- set element properties. omit property prefix if used inside behavior tag -->
    <string name='.name'>value</string>
  </behavior>
</elementClass>
</code>
