 Grabber enabled changed. Grabber enabled changed.
 +
 +====== Behavior Tree Actions ======
 +
 +This behavior adds these behavior tree actions if behavior tree is present. If behavior has non-empty identifier replace ''grabber'' with ''grabber(id)''.
 +
 +===== grabber.set =====
 +
 +Set one or more grabber parameters.
 +
 +^Parameter^Value^Description^
 +|enabled|''true'', ''false''|Grabber is enabled|
 +
 +This is an example of using this action:
 +<code xml>
 +<action name='grabber.set'>
 +  <parameter name='enabled'>true</parameter>
 +</action>
 +</code>
 +
 +===== grabber.update =====
 +
 +Update grabber.
 +
 +^Parameter^Value^Description^
 +|release| |Release grab spot if grabbing one.|
 +|interactElement.assign|string|Assign grab spot element to [[behavior_interactelement|ECBehaviorInteractElement]] with identifier matching value string. Action fails if no element is grabbed or interact element behavior is absent|
 +|interact|string|Interact with grab spot. If element is absent action fails. Runs interaction with name value. If interaction with name value is absent fails action. If interaction returns false fails action. Otherwise action succeeds.|
 +|interact.parameters|string|Optional parameters to use with ''interaction''.|
 +
 +This is an example of using this action:
 +<code xml>
 +<action name='grabber.update'>
 +  <parameter name='release'/>
 +</action>
 +</code>
 +
 +===== grabber.check =====
 +
 +Check one or more grabber parameters. Action succeeds if all parameter value matches their respective grabber parameter otherwise action fails. This action is typically used as first action in a sequence to run the sequence only if a grabber parameter matches (or not).
 +
 +^Parameter^Value^Description^
 +|enabled|''true'', ''false''|Grabber is enabled|
 +|grabbing|''true'', ''false''|Grabber is grabbing a grab spot|
 +|interact.name|string|Name of interaction|
 +|interact.has|''true'', ''false''|Has grab spot and interaction with name ''interaction.name'' is present|
 +|interact.query|''true'', ''false''|Interact with grab spot and test result. Condition is true if grab spot is present, interaction with name ''interaction.name'' is present and interaction returns true. It is recommended to use here only interactions without side effects (hence query interactions).|
 +|interact.parameters|string|Optional parameters to use with ''interaction.query''.|
 +|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='grabber.check'>
 +    <parameter name='grabbing'>true</parameter>
 +  </action>
 +  <!-- actions here run only if grabber is grabbing a grab spot -->
 +</sequence>
 +</code>
 +
 +====== Behavior Tree Conditions ======
 +
 +This behavior adds these behavior tree conditions if behavior tree is present. If behavior has non-empty identifier replace ''grabber'' with ''grabber(id)''.
 +
 +===== grabber.check =====
 +
 +Check one or more grabber parameters. Conditions returns true if all parameter value match their respective grabber parameter. This condition is typically used to run an action or sequence of actions as long as grabber conditions are true.
 +
 +^Parameter^Value^Description^
 +|grabber.enabled|''true'', ''false''|Grabber is enabled|
 +|grabber.grabbing|''true'', ''false''|Grabber is grabbing a grab spot|
 +|grabber.interact.name|string|Name of interaction|
 +|grabber.interact.has|''true'', ''false''|Has grab spot and interaction with name ''interaction.name'' is present|
 +|grabber.interact.query|''true'', ''false''|Interact with grab spot and test result. Condition is true if grab spot is present, interaction with name ''interaction.name'' is present and interaction returns true. It is recommended to use here only interactions without side effects (hence query interactions).|
 +|grabber.interact.parameters|string|Optional parameters to use with ''interaction.query''.|
 +
 +This is an example of using this condition:
 +<code xml>
 +<action name='myAction' id='doing something'>
 +  <parameter name='grabber.grabbing'>true</parameter>
 +  <condition>grabber.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. If behavior has non-empty identifier replace ''grabber'' with ''grabber(id)''.
 +
 +===== grabber.enabled =====
 +
 +Grabber has been enabled.
 +
 +===== grabber.disabled =====
 +
 +Grabber has been disabled.
 +
 +===== grabber.grabbed =====
 +
 +Grabber grabbed grab spot.
 +
 +===== grabber.released =====
 +
 +Grabber released grab spot.
 +
 +===== grabber.touch =====
 +
 +Start touching grab spot.
 +
 +===== grabber.untouch =====
 +
 +Stop touching grab spot.
