APE – Basketball

To play around a little more from the find of the draggable objects in APE I made a little demo of a basketball game.

Here is the code:

package {
    import flash.display.Sprite;
    import flash.events.Event;
	import flash.events.MouseEvent;

    import org.cove.ape.*;

	public class Main extends Sprite {

		private var circle:DragableCircleParticle;
		private var circle2:DragableCircleParticle;

		public function Main()
		{
			init();
		}

		private function init():void
		{
			stage.frameRate = 55;

			// Initialize the engine. The argument here is the time step value.
			// Higher values scale the forces in the sim, making it appear to run
			// faster or slower. Lower values result in more accurate simulations.
			APEngine.init(1/4);

			// set up the default diplay container
			APEngine.container = this;

			APEngine.addMasslessForce(new Vector(0,5));

			var defaultGroup:Group = new Group();

			defaultGroup.collideInternal = true;

			/* RECTANGLE PROPERTIES
				x:Number,
				y:Number,
				width:Number,
				height:Number,
				rotation:Number = 0,
				fixed:Boolean = false,
				mass:Number = 1,
				elasticity:Number = 0.3,
				friction:Number = 0
			*/
            var floor:RectangleParticle = new RectangleParticle(stage.stageWidth/2, stage.stageHeight + 48, stage.stageWidth, 100, 0, true, 10);
            defaultGroup.addParticle(floor);

			var ceil:RectangleParticle = new RectangleParticle(stage.stageWidth/2, -50, stage.stageWidth, 100, 0, true, 10);
            defaultGroup.addParticle(ceil);

			var left:RectangleParticle = new RectangleParticle(-25, stage.stageHeight/2, 50, stage.stageHeight, 0, true, 10);
            defaultGroup.addParticle(left);

			var right:RectangleParticle = new RectangleParticle(stage.stageWidth+25, stage.stageHeight/2, 50, stage.stageHeight, 0, true, 10);
            defaultGroup.addParticle(right);

			/* CIRCLE PROPERTIES

           	circle = new DragableCircleParticle(350, 150, 30, false, 20, .5);
			circle.setStyle(0, 0, 0, 0x993300);
			defaultGroup.addParticle(circle);

			/* HOOP & NET

			var hl:CircleParticle = new CircleParticle( stage.stageWidth - 180, 300, 5, true );
			defaultGroup.addParticle ( hl ); // hoop top left

			APEngine.addGroup(defaultGroup);
			addEventListener(Event.ENTER_FRAME, run);
		}

		private function run(e:Event):void
		{

			APEngine.paint();
