Springing with multiple targets

1

Sorry, worked it out.
Thanks for anyone who read the thread before.

EDIT: The problem was that I had a general Ball class with functions for velocity and acceleration. However, I had forgotten to define an initial acceleration and velocity value in the class. So, vx was undefined, but it was trying to add this value to the x value of the Ball on every frame. I’m unsure why, but this resulted in the x (and y) values defaulting to -107374182.4, and the Ball disappearing from stage.

So if you’re making a class like that, be sure to define the velocity and the acceleration at the start :stuck_out_tongue:

Ball.as:


package
{
	import flash.display.Sprite;
	import flash.events.Event;
	public class Ball extends Sprite
	{
		public var vx:Number;
		public var vy:Number;
		public var ay:Number;
		public var ax:Number;
		private var _color:uint;
		public var radius:Number;
		public function Ball(color:uint = 0xFFFFFF00, radius:Number = 40):void
		{
			this.radius = radius;
			this.color = color;
			init();
		}
		private function init():void
		{
			with (graphics)
			{
				beginFill(_color, 0.6);
				drawCircle(0, 0, radius);
				endFill();
			}
			**ax = 0;
			ay = 0;
			vy = 0;
			vx = 0;** *//It was this piece of code that I'd forgotten to include.*
			addEventListener(Event.ENTER_FRAME, moveBall, false, 0, true);
			addEventListener(Event.REMOVED_FROM_STAGE, removeBall, false, 0, true);
		}
		public function moveBall(evt:Event):void
		{
			vy += ay;
			vx += ax;
			vx *= 0.95;
			vy *= 0.95;
			x += vx;
			y += vy;
		}
		private function removeBall(evt:Event):void
		{
			removeEventListener(Event.ENTER_FRAME, moveBall);
			removeEventListener(Event.REMOVED_FROM_STAGE, removeBall);
		}
		public function set color(c:uint):void
		{
			if (c <= 0xFFFFFF)
			{
				_color = c;
			} else 
			{
				_color = Math.random() * 0xFFFFFF;
			}
		}
	}
}
