Hello,

I’m trying to add another instance of my GurlBall to the stage, whenever a gBall instance collides with a bBall instance. (Does that make sense?) I have a GurlBall, Ball, and a BallCollision actionscript file.

GurlBall.as:

```auto

private function hitTest():void {// for (var i:int = 0; i < Main.bFishList.length; i++)
		{
			if (this.hitTestObject(BallCollision.bFishList*))
			{
				trace("hitEnemy");
				speedX = -speedX;
				speedY = -speedY;
				addChild(this);
				
			}
		}

```

How would I reference the bBall instance in the BallCollision file, and how can I add a gBall instance when they collide?
