 ===== component.* ===== ===== component.* =====
-This behavior adds a child [[behavior_component|ECBehaviorComponent]] to the element class to show the hand in the game world. The child behavior has the identifier "vrHand" or "vrHand(id)". The child behavior has the element class property prefix "vrHand.component." or "vrHand(id).component.". 
  
-Hence to set for example the component model of the right hand use the element class property "vrHand(right).component.model"+This behavior adds a child [[behavior_component|ECBehaviorComponent]] to the element class to show the hand in the game world. The child behavior has the identifier ''vrHand'' or ''vrHand(id)''. The child behavior has the element class property prefix ''vrHand.component.'' or ''vrHand(id).component.'' . 
 + 
 +Hence to set for example the component model of the right hand use the element class property ''vrHand(right).component.model'' . 
 + 
 +====== Events ====== 
 + 
 +===== controllerAttached ===== 
 + 
 +Hand controller attached and ready to use. 
 + 
 +===== controllerDetached ===== 
 + 
 +Hand controller detached and no more usable. 
 + 
 +====== Behavior Tree Actions ====== 
 + 
 +This behavior adds these behavior tree actions if behavior tree is present. If behavior has non-empty identifier replace ''vrHand'' with ''vrHand(id)''. 
 + 
 +===== vrHand.check ===== 
 + 
 +Check one or more VR hand parameters. Action succeeds if all parameter value matches their respective VR hand parameter otherwise action fails. This action is typically used as first action in a sequence to run the sequence only if a VR hand parameter matches (or not). 
 + 
 +^Parameter^Value^Description^ 
 +|attached|''true'', ''false''|VR controller is attached| 
 +|wait| |If present action returns BTResult.running instead of BTResult.failed to wait until the checks are all fulfilled| 
 + 
 +This is an example of using this action: 
 +<code xml> 
 +<sequence> 
 +  <action name='vrHand.check'> 
 +    <parameter name='attached'>true</parameter> 
 +  </action> 
 +  <!-- actions here run only if VR hand controller is attached --> 
 +</sequence> 
 +</code> 
 + 
 +====== Behavior Tree Conditions ====== 
 + 
 +This behavior adds these behavior tree conditions if behavior tree is present. If behavior has non-empty identifier replace ''vrHand'' with ''vrHand(id)''. 
 + 
 +===== vrHand.check ===== 
 + 
 +Check one or more VR hand parameters. Conditions returns true if all parameter value match their respective VR hand parameter. This condition is typically used to run an action or sequence of actions as long as VR hand conditions are true. 
 + 
 +^Parameter^Value^Description^ 
 +|vrHand.attached|''true'', ''false''|VR controller is attached| 
 + 
 +This is an example of using this condition: 
 +<code xml> 
 +<action name='myAction' id='doing something'> 
 +  <parameter name='vrHand.attached'>true</parameter> 
 +  <condition>vrHand.check</condition> 
 +</action>

 + 
 +====== State Machine Actions ====== 
 + 
 +Same as [[#behavior_tree_actions|Behavior Tree Actions]]. 
 + 
 +====== State Machine Conditions ====== 
 + 
 +Same as [[#behavior_tree_conditions|Behavior Tree Conditions]]. 
 + 
 +====== State Machine Events ====== 
 + 
 +This behavior sends these state machine events. If behavior has non-empty identifier replace ''vrHand'' with ''vrHand(id)''. 
 + 
 +===== vrHand.attached ===== 
 + 
 +VR controller has been attached. 
 + 
 +===== vrHand.disabled ===== 
 + 
 +VR controller has been detached.
