Behavior element behavior show/hide element if triggered.

If trigger evaluates to true the element is set visible and touchable others not.

This behavior can be used only once on an element.

Element class properties have the prefix showElement..

Set trigger to show element.

• Full name: showElement.trigger or showElement({id}).trigger
• Type: string
• Default Value: empty string
• Example (*.deeclass)

  <string name='showElement.trigger'>@playerEnterSpot & @ghostPresent</string>

This behavior has no events.

This behavior adds these behavior tree actions if behavior tree is present.

Set one or more show element parameters.

This is an example of using this action:

<action name='showElement.set'>
  <parameter name='shown'>true</parameter>
</action>

Check one or more show element parameters. Action succeeds if all parameter value matches their respective show element parameter otherwise action fails. This action is typically used as first action in a sequence to run the sequence only if a show element parameter matches (or not).

This is an example of using this action:

<sequence>
  <action name='showElement.check'>
    <parameter name='shown'>true</parameter>
  </action>
  <!-- actions here run only if show element is shown -->
</sequence>

This behavior adds these behavior tree conditions if behavior tree is present.

Check one or more show element parameters. Conditions returns true if all parameter value match their respective show element parameter. This condition is typically used to run an action or sequence of actions as long as show element conditions are true.

This is an example of using this condition:

<action name='myAction' id='doing something'>
  <parameter name='showElement.shown'>true</parameter>
  <condition>showElement.check</condition>
</action>

Same as Behavior Tree Actions.

Same as Behavior Tree Conditions.

This behavior sends these state machine events.

Element has been shown.

Element has been hidden.

This behavior requires no other behaviors.

• ECBehaviorBehaviorTree: Add actions and conditions for behavior trees to use.
• ECBehaviorStateMachine: Add actions and conditions for state machine to use and events to send to the state machine.

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

ECBehaviorShowElement.

Since DragonScript Module Version 1.19

• Make element appear if player touches a trigger.

This example defines an element which contains a resources.

class MyElement extends BehaviorElementClass
  public var ECBehaviorComponent component
  public var ECBehaviorCollider collider
  public var ECBehaviorShowElement showElement
  func new()
    component = ECBehaviorComponent.new(this, null)
    collider = ECBehaviorCollider.new(this, component)
    showElement = ECBehaviorShowElement.new(this)
  end
end

Using element class supporting adding behaviors the behavior can be added like this:

<?xml version='1.0' encoding='UTF-8'?>
<elementClass name='MyClass' class='GenericBehaviorElement'>
  <behavior type='ECBehaviorComponent'/>
  <behavior type='ECBehaviorCollider'/>
 
  <behavior type='ECBehaviorShowElement'>
    <!-- optional: use BaseGameApp trigger table. game can add more supported values.
                   default is 'default' -->
    <string name='triggerTable'>default</string>
 
    <!-- optional: identifier of ECBehaviorTriggered to synchronize with or empty
                   string to not synchronize. default is empty string. -->
    <string name='trigger.synchronize'>other</string>
 
    <!-- optional: use behavior tree with id instead of empty string -->
    <string name='behaviorTree'>second</string>
 
    <!-- optional: use state machine with id instead of empty string -->
    <string name='stateMachine'>second</string>
 
    <!-- set element properties. omit property prefix if used inside behavior tag -->
    <string name='.name'>value</string>
  </behavior>
</elementClass>
