Controlling Sprite with Classes

Ok the solution to this will probably be so simple, it'll hurt me!
I used to know how to do this, but have since forgotten, and can't remember how, or find the resource I used to learn it in the first place.

Basically, I want to move a sprite made in AS3, with an external class.

This is the code I want to use as an example, just so I can get to grips with it, and apply it in other things.

Library:
MovieClip with AS name of "orb"

Main File Timeline:

Code:

---

import flash.events.Event;

addEventListener(Event.ENTER_FRAME, enteringFrame);

function enteringFrame(e:Event):void{
        var spr:orb = new orb();
        spr.x = 175;
        spr.y = 30;
        spr.addEventListener(Event.ENTER_FRAME, animateOrb);
        addChildAt(spr,0);
}

function animateOrb(e:Event):void{
        e.target.animate();
}

---

animate.as

Code:

---

package  {
        import flash.display.MovieClip;
       
        public class animate extends MovieClip{

                public function animate() {
                        this.y += 10;
                }
        }
}

---

I seem to remember linking the as file to the movieclip somehow, but the error i get for this right now is:

Code:

---

TypeError: Error #1006: animate is not a function.
        at animate/animateOrb()

---

What do I need to make sure of to get this to work?

Thanks for any help in advance!

ActionScript Code:

package {
    import flash.display.MovieClip;

    public class animate extends MovieClip {
        public function animate() {
        }
        public function Ani(Y:int):int {
            //this.y += 10;
            return Y+1;
        }
    }
}

Actionscript Code:

import flash.events.Event;

addEventListener(Event.ENTER_FRAME, enteringFrame);

function enteringFrame(e:Event):void {
    removeEventListener(Event.ENTER_FRAME, enteringFrame);
    var spr:orb = new orb();
    spr.x = 175;
    spr.y = 30;
    spr.addEventListener(Event.ENTER_FRAME, animateOrb);
    addChildAt(spr,0);
}

function animateOrb(e:Event):void {
    var a:animate=new animate();
    e.target.y=a.Ani(e.target.y);
}

This will work. But its not a good solution.

You need your animate method to be a method of orb, since you are calling it on an orb instance. Alternatively, you could pass the orb to animate rather than calling it as a method of orb.

I'd create an orb.as file, and copy/move the animate function into that. It does not need to be in animate.as, which I assume is your document class.

By convention, class names should begin with an uppercase letter, and method/variable names should begin with a lowercase letter.

Yes, you follow what 5TonsOfFlax suggested you to do if you don't have any other plan to make it in another separate class.
