Class help

Question

Hi
I cant figure out what my problem is here.
I have created 2 classes here one that creates a circle
called ball
and one that has handlers to drag the circle.
My main class MouseMoveDrag is connected to a document class
and it is directed to the as file.
However I keep getting this message
"1120: Access of undefined property ball.

I'm wrestling with a similar problem at the moment mate.
1120: Access of undefined property ball
This error simply means that it can't find the specified
object, in this case "ball".
What you have to do is rename the init function in
MouseMoveDrag.as to something else, make it public and in Ball.as
you have to call the renamed init function in MouseMoveDrag and
pass the ball sprite.
So, you might want to have at the end of your init function
in Ball,as:
renamedInitFunction(ball);
and your renamed function header in MouseMoveDrag will look
something like this:
public function renamedInitFunction(ball):void {
If you get an error saying could not find
renamedInitFunction(ball) from Ball.as, then try making Ball.as
extend MouseMoveDrag, so like this:
public class Ball extends MouseMoveDrag {
This simply means that Ball will inherit properties from
MouseMove Drag including functions ;)
