Particle System

I have just started playing around with artistic art in Flash. I started off playing with particles, so here you go. I developed a simple Particle class, and here is how to implement it.

To download the class: http://harry-northover-code-store.googlecode.com/files/Particle.zip

To download the demo: http://harry-northover-code-store.googlecode.com/files/Demo.zip

Here is a screene:

Here’s the code:

package {
 
	import com.harrynorthover.particle.Particle;
	import flash.events.Event;
	import flash.display.Sprite;
 
	public class ParticleTest extends Sprite {
 
		private var emmiterX:Number = stage.stageWidth / 2;
		private var emmiterY:Number = stage.stageHeight / 2;
 
		public function ParticleTest() {
			stage.addEventListener(Event.ENTER_FRAME, onLoop, false, 0, true);
		}
 
		private function onLoop(evt:Event) {
			var p:Particle = new Particle(emmiterX, emmiterY, Math.random() * 11 - 6, Math.random() * -20, 1, Math.random() * 0xFFFFFF, 50, true);
			addChild(p);
		}
 
	}
}

To get this working, all you need to do is create a MovieClip with a linkage ID of ‘Ball’, and you should be ready to go.

So there you are! If anyone would like me to explain the code, feel free to contact me.
