The base class used by all the Flex compatible renderers. This class manages
various aspects of the rendering process.
The class will add every emitter it should renderer to it's internal
collection of emitters. It will listen for the appropriate events on the
emitter and will then call the protected methods addParticle, removeParticle
and renderParticles at the appropriate times. Many derived classes need
only implement these three methods to manage the rendering of the particles.
protected var _particles:Arrayemitters:Vector.<Emitter>
The array of all emitters being rendered by this renderer. This is exposed
to enable setting of the emitters in mxml files. It is not intended to be used
from Actionscript code.
Implementation public function get emitters():Vector.<Emitter> public function set emitters(value:Vector.<Emitter>):voidpublic function FlexRendererBase()
The constructor creates a FlexRendererBase class.
public function addEmitter(emitter:Emitter):void
Adds the emitter to the renderer. When an emitter is added, the renderer
invalidates its display so the renderParticles method will be called
on the next render event in the frame update.
Parameters
| emitter:Emitter — The emitter that is added to the renderer.
|
protected function addParticle(particle:Particle):void
The addParticle method is called when a particle is added to one of
the emitters that is being rendered by this renderer.
Parameters
protected function emitterUpdated(ev:EmitterEvent):void Parameters
override protected function measure():void
private
public function removeEmitter(emitter:Emitter):void
Removes the emitter from the renderer. When an emitter is removed, the renderer
invalidates its display so the renderParticles method will be called
on the next render event in the frame update.
Parameters
| emitter:Emitter — The emitter that is removed from the renderer.
|
protected function removeParticle(particle:Particle):void
The removeParticle method is called when a particle is removed from one
of the emitters that is being rendered by this renderer.
Parameters
protected function renderParticles(particles:Array):void
The renderParticles method is called during the render phase of
each frame if the state of one of the emitters being rendered
by this renderer has changed.
Parameters
| particles:Array — The particles being managed by all the emitters
being rendered by this renderer. The particles are in no particular
order.
