Detailed Description

Behavior element behavior adding support to track if actors look at element.

This behavior tracks if actors are looking at the element. If actors start looking at the element they are added to the list and listeners are notified. If the actors stop looking at the element they are removed from the list and listeners are notified. The actors can be an NPC or the player. The behavior itself is passive. It requires to be triggered by the actor elements. The ECBehaviorLookAt behavior provides this functionality.

This behavior supports persistable element classes (setPersistable).

Member Function Documentation

◆ addListenerFactory() [1/2]

void Dragengine.Scenery.ECBehaviorLookedAt.addListenerFactory ( Block blockFactory )

Add listener factory using block.

Block receives as parameter Instance and returns Listener.

◆ addListenerFactory() [2/2]

void Dragengine.Scenery.ECBehaviorLookedAt.addListenerFactory ( ListenerFactory factory )

Add listener factory.

◆ createInstance()

ECBehaviorInstance Dragengine.Scenery.ECBehaviorLookedAt.createInstance ( BehaviorElement element )

Create Behavior instance.

Implements Dragengine.Scenery.ECBehavior.

◆ dispose()

void Dragengine.Scenery.ECBehaviorLookedAt.dispose ( )

Dispose of behavior.

Reimplemented from Dragengine.Scenery.DefaultECBehavior.

◆ forEachListenerFactory()

void Dragengine.Scenery.ECBehaviorLookedAt.forEachListenerFactory ( Block ablock )

Visit listener factories with block with argument ListenerFactory.

◆ getBehaviorIn()

static ECBehaviorLookedAt Dragengine.Scenery.ECBehaviorLookedAt.getBehaviorIn ( BehaviorElementClass eclass )

static

Get behavior in element class or null if absent.

Use this method to check if a particular BehaviorElementClass contains a behavior of type ECBehaviorComponent.

◆ getInstanceIn()

static Instance Dragengine.Scenery.ECBehaviorLookedAt.getInstanceIn ( BehaviorElement element )

static

Get instance in element or null if absent.

Use this method to check if a particular BehaviorElement contains a behavior instance of type ECBehaviorLookedAt.Instance . If more than one instance is present returns the first instance.

◆ instance()

Instance Dragengine.Scenery.ECBehaviorLookedAt.instance ( BehaviorElement element )

Get instance in element from owner element class.

◆ new()

ECBehaviorLookedAt Dragengine.Scenery.ECBehaviorLookedAt.new ( BehaviorElementClass eclass )

Create behavior element class.
