   Hi, exscuse for my English,
   I have this problem: I want to add a MouseEvent in this simple code just to trigger the particles movement:
   
   
   [SWF(width="500", height="500", frameRate="60", backgroundColor="#000000")]
   
   var emitter:Emitter2D = new Emitter2D();
   var render:BitmapRenderer = new BitmapRenderer(new Rectangle(0, 0, 500, 500), true);
   
   emitter.counter = new Blast(50);
   
   emitter.addInitializer(new SharedImage(new RadialDot(4)));
   emitter.addInitializer(new ColorInit(0xFF00FF00, 0x0000FFFF));
   emitter.addInitializer(new Position(new RectangleZone(0, 0, 500, 500)));
   
   emitter.addEventListener(MouseEvent.CLICK, movement);
   
   function movement(e:MouseEvent) {
   emitter.addInitializer(new Velocity(new RectangleZone(20, 0, 0, 20)));
   emitter.addAction(new Move());
   }
   
   render.addEmitter(emitter);
   addChild(render);
   
   emitter.start();
   
   I know that this addEventListener does nothing but I would know what is the right way.
   Thank!

   I guess this does not work because the emitter is not a clickable sprite or movieclip. If you want this to work when you click anywhere on the stage then try using
   
   stage.addEventListener(MouseEvent.CLICK, movement);

   Exactly. Use any clickable object to trigger the event, including the stage. The emitter is not clickable.
   
   The particles can be made clickable -
   
   render.mouseEnabled = true;
render.mouseChildren = true;
render.addEventListener(MouseEvent.CLICK, movement);

   Thank guys! But I tried with this code and nothing happens:
   
   render.mouseEnabled = true;
render.mouseChildren = true;

render.addEventListener(MouseEvent.CLICK, movement);

function movement(e:MouseEvent) {
emitter.addInitializer(new Velocity(new RectangleZone(20, 0, 0, 20)));
emitter.addAction(new Move());
}
   
   I don't understand why....

   Ok, I understand that I have to put the emitter.start() inside the function but, in this way, before the click there arent any particles on the stage.
   What I want, if possible, is to start the movement of the particles when they are just on the stage....

   Don't put the emitter.start() inside the function, but do put the emitter.addAction(new Move()) inside it. The particles won't move until you add this action to the emitter.

   I tried to leave out the function emitter.start() and just put the emitter.addAction(new Move()) inside it (like the example in my post before) but the particles doesn't move after the click.

   In your previous example, you should move the velocity initializer out of the function. Basically, you set the emitter up with all its initializers, including velocity. Then you start it, causing the particles to be initilized and so appear. Then when the click happens you add the move action, which causes them to move.

   Really thank you Richard!
   Now is all ok, very good explanation!
