Access of Undefined Property from a Class

PHP Code:

---

package {
    import flash.display.MovieClip;
    import flash.events.Event;

    public class DumbClass extends MovieClip {
    
        var dumbXS:Number = 0;
        var dumbYS:Number = 0;
        var dumbACC:Number = 0.6;
        var dumbDEC:Number = 0.92;
        
        public function DumbClass() {
            this.addEventListener(Event.ENTER_FRAME, DumbMove);
        }

        public function DumbMove(evt:Event):void {
            //Increases Speed
            this.x += dumbXS;
            this.y += dumbYS;
            //Reference to a MovieClip on stage called "user".
            if (user.y < this.y) {
                dumbYS -= dumbACC;
            }
            //Reference to a MovieClip on stage called "user".
            if (user.y > this.y) {
                dumbYS += dumbACC;
            }
            //Reference to a MovieClip on stage called "user".
            if (user.x < this.x) {
                dumbXS -= dumbACC;
            }
            //Reference to a MovieClip on stage called "user".
            if (user.x > this.x) {
                dumbXS += dumbACC;
            }
            ///Decrease Speed
            dumbYS *= dumbDEC;
            dumbXS *= dumbDEC;
        }
    }
}

I get an error that "user" is an undefined property even though its on the stage any ideas how I can fix this? :crying:

You need to declare it as a public variable first. Also it is a good habit to always add the attributes public and private even Flash does it for you. It helps the compiler and helps you later when you need to debug.

How would I go about that?

public class DumbClass extends MovieClip {
public var user:MovieClip;
var dumbXS:Number = 0;

My guess is that user is a MovieClip.

Yes the user is a a MC with the instance "user" on stage. The idea is that when ever space is pressed a instance of the class is created on the stage. But from within the class it cannot seem to get the user.x/y value.

Thats how they spawn atm.

PHP Code:

---

function spawnCircle() {
    var screen_side:Number = Math.round(Math.random()* 3);
    var DumbTarget:DumbClass = new DumbClass();
    //this["dumbTarget" + dumbLoop] = dumbTemp;
    addChild(DumbTarget);
    if (screen_side == 0) {
        DumbTarget.x = -15;
        DumbTarget.y = -15;
    }
    if (screen_side == 1) {
        DumbTarget.x = 815;
        DumbTarget.y = -15;
    }
    if (screen_side == 2) {
        DumbTarget.x = 815;
        DumbTarget.y = 615;
    }
    if (screen_side == 3) {
        DumbTarget.x = -15;
        DumbTarget.y = 615;
    }
}

I tried
public var user:MovieClip;

and

public var user:MovieClip = new user_lib; (Because user_lib is the AS Esport name for the MC "user")

Fact is I want to be able to tell the class where on stage the MC "user" is but when ever I use user (because that's its instance name on stage) it sees it as an undefined property.

try
public var user:user_lib;

TypeError: Error #1009: Cannot access a property or method of a null object reference.

package {
    import flash.display.MovieClip;
    import flash.events.Event;

    public class DumbClass extends MovieClip {
        
        public var user:user_lib;
        var dumbXS:Number = 0;
        var dumbYS:Number = 0;
        var dumbACC:Number = 0.6;
        var dumbDEC:Number = 0.92;
        
        public function DumbClass() {
            this.addEventListener(Event.ENTER_FRAME, DumbMove);
        }

        public function DumbMove(evt:Event):void {
            //Increases Speed
            this.x += dumbXS;
            this.y += dumbYS;
            //Reference to a MovieClip on stage called "user".
            if (user.y < this.y) {
                dumbYS -= dumbACC;
            }
            //Reference to a MovieClip on stage called "user".
            if (user.y > this.y) {
                dumbYS += dumbACC;
            }
            //Reference to a MovieClip on stage called "user".
            if (user.x < this.x) {
                dumbXS -= dumbACC;
            }

    }

I heard I have to use a property manager or constructor but I have no idea which either of them are.

Is the class your Document class?

No its associated with an MC in the main .fla's library. I've attached the project directory.
