Behavior adding support to actors to step aside if told.

This behavior is useful for situations where actors can get in the way of the player or other actors. The behavior is a reactive behavior not acting by itself. It is triggered by ECBehaviorClearPath or other behaviors supporting it if the find a future collision.

This behavior has no effect if actor mover has a goal set.

This behavior can be disabled temporarily to prevent actors from stepping aside.

This behavior can be used only once on an element. The behavior always has identifier empty string.

Element class properties have the prefix stepAside. .

Determines if the behavior is initially enabled.

• Full name: stepAside.enabled
• Type: boolean
• Default Value: true
• Example (*.deeclass)

  <boolean name='stepAside.enabled'>false</boolean>

Avoid radius. Actor tries to move to a position with this distance away from the moving lane of the actor requesting to step aside.

• Full name: stepAside.radius
• Type: floating point
• Minimum Value: 0
• Default value: 0.4
• Example (*.deeclass)

  <float name='stepAside.radius'>0.5</float>

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

Set one or more step aside parameters.

This is an example of using this action:

<action name='stepAside.set'>
  <parameter name='enabled'>true</parameter>
</action>

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

This is an example of using this action:

<sequence>
  <action name='stepAside.check'>
    <parameter name='enabled'>true</parameter>
  </action>
  <!-- actions here run only if step aside is enabled -->
</sequence>

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

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

This is an example of using this condition:

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

Same as Behavior Tree Actions.

Same as Behavior Tree Conditions.

This behavior sends these state machine events.

Step aside.

• ECBehaviorActorMover

• 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 enabled state.

ECBehaviorStepAside.

Since DragonScript Module Version 1.4

• Avoid actors blocking the path of other actors. The moving actors can make blocking actors move away.
• Avoid player blocking actors or actors blocking the player.
• Create situations where player or other actors are running and other actors move out of the way ahead of time.

class ExampleElementClass extends BehaviorElementClass
   public var ECBehaviorComponent component
   public var ECBehaviorCollider collider
   public var ECBehaviorColliderAI colliderAI
   public var ECBehaviorLocomotion locomotion
   public var ECBehaviorNavigator navigator
   public var ECBehaviorActorMover actorMover
   public var ECBehaviorStepAside stepAside
   
   public func new() super("ExampleElement")
     // create required behaviors
     component = ECBehaviorComponent.new(this)
     collider = ECBehaviorCollider.new(this, component)
     colliderAI = ECBehaviorColliderAI.new(this, collider)
     locomotion = ECBehaviorLocomotion.new(this, colliderAI)
     navigator = ECBehaviorNavigator.new(this)
     actorMover = ECBehaviorActorMover.new(this, locomotion, navigator, null)
     
     // create step aside behavior
     stepAside = ECBehaviorStepAside.new(this, actorMover)
   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='ECBehaviorColliderAI'/>
  <behavior type='ECBehaviorLocomotion'/>
  <behavior type='ECBehaviorNavigator'/>
  <behavior type='ECBehaviorActorMover'/>
 
  <behavior type='ECBehaviorStepAside'>
    <!-- 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 -->
    <float name='.radius'>0.5</float>
  </behavior>
</elementClass>
