 +====== Behavior Tree Actions ======
 +
 +This behavior adds these behavior tree actions if behavior tree is present.
 +
 +===== lookAt.check =====
 +
 +Check one or more look-at parameters. Action succeeds if all parameter value matches their respective look-at parameter otherwise action fails. This action is typically used as first action in a sequence to run the sequence only if a look-at parameter matches (or not).
 +
 +^Parameter^Value^Description^
 +|enabled|''true'', ''false''|Look-at is enabled|
 +|lookAt|''true'', ''false''|Is looking at element|
 +|lookAt.distance.less|float|Distance to look-at element is less than value meters|
 +|lookAt.distance.greater|float|Distance to look-at element is greater than value meters|
 +|lookAt.player|''true'', ''false''|Is looking at player|
 +|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='lookAt.check'>
 +    <parameter name='lookAt.player'>true</parameter>
 +  </action>
 +  <!-- actions here run only if looking at player -->
 +</sequence>
 +</code>
 +
 +====== Behavior Tree Conditions ======
 +
 +This behavior adds these behavior tree conditions if behavior tree is present.
 +
 +===== lookAt.check =====
 +
 +Check one or more look-at parameters. Conditions returns true if all parameter value match their respective look-at parameter. This condition is typically used to run an action or sequence of actions as long as look-at conditions are true.
 +
 +^Parameter^Value^Description^
 +|enabled|''true'', ''false''|Look-at is enabled|
 +|lookAt.lookAt|''true'', ''false''|Is looking at element|
 +|lookAt.lookAt.distance.less|float|Distance to look-at element is less than value meters|
 +|lookAt.lookAt.distance.greater|float|Distance to look-at element is greater than value meters|
 +|lookAt.lookAt.player|''true'', ''false''|Is looking at player|
 +
 +This is an example of using this condition:
 +<code xml>
 +<action name='myAction' id='doing something'>
 +  <parameter name='lookAt.enabled'>true</parameter>
 +  <condition>lookAt.check</condition>
 +</action>
 +</code>
 +
 +====== 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.
 +
 +===== lookAt.enabled =====
 +
 +Look-at has been enabled.
 +
 +===== lookAt.disabled =====
 +
 +Look-at has been disabled.
 +
 +===== lookAt.lookAt =====
 +
 +Looking at an element. Send if looking at an element when previously not looking at an element or looking at a different element.
 +
 +===== lookAt.noLookAt =====
 +
 +Not looking at an element. Send if not looking at an element when previously has been looking at an element.
