[F8] Why is it that when I trace(this._x);...

...I get "NaN"?

In other words, you question is:
Why is it that when I trace(this._x), i get Not A Number?

There could be a lot of reasons depending on your other codes and set up.

If a clip is on the stage, shouldn't it always have an _x and _y?

and that code is, i guess, on a frame inside that clip? then you should get a number.

The trace resides within a function that is in a frame within the movie clip. I call the function using setInterval() like you suggested I do in another thread. The function is being called at the appropriate time, but anything that relies on the specific clip's properties (_x, _y, _xscale, etc.) come up as NaN.

Is it the way I am referencing the clip?

On the first and only frame of the main timeline I have:

Code:

---

_global.i = 0;

On the first and only frame of the movieclip, I have:

Code:

function Reproduction(){
        max = 10;
        min = 1;
        maxa = 360;
        mina = 0;

        hypot = Math.floor(Math.random()*(max-min+1)+min);

        angul = Math.floor(Math.random()*(maxa-mina+1)+mina);

        oppo = Math.sin(angul*Math.PI/180)*hypot
        adja = Math.cos(angul*Math.PI/180)*hypot

        if (angul <= 90){
                _root.attachMovie("base_1","treetree" + _global.i + 1, _global.i + 1,{_x:adja + this._x, _y:oppo + this._y});
        } else if ((angul >90) && (angul<=180)){
                _root.attachMovie("base_1","treetree" + _global.i + 1, _global.i + 1,{_x:adja + this._x, _y:oppo - this._y});               
        } else if ((angul >180) && (angul<=270)){
                _root.attachMovie("base_1","treetree" + _global.i + 1, _global.i + 1,{_x:adja - this._x, _y:oppo - this._y});
        } else if ((angul >270) && (angul<=360)){
                _root.attachMovie("base_1","treetree" + _global.i + 1, _global.i + 1,{_x:adja - this._x, _y:oppo + this._y});
        }
        _global.i = _global.i + 1;
        trace("hypot is " + hypot);
        trace(this._y);
}

function Death(){
        maxa = 2;
        mina = 0;
        Yup = Math.random() * (maxa - mina + 1) + mina;
        if (Yup > 1){
                this.removeMovieClip();
                trace("a death occurred");
        }
}

function Growth(){
        maxc = 1;
        minc = 0;
        scaleit = Math.random()*(maxc - minc + 1) + minc;
        this._xscale = this._xscale + scaleit
        this._yscale = this._yscale + scaleit
        trace("The xscale is " + this._xscale);
}

setInterval(Reproduction, 10000);
setInterval(Growth, 10000);
setInterval(Death, 10000);

I added the traces to see if the functions were being called and they are. Any reference to "this" is undefined.

Does anybody have any ideas why this is happening?

you need to make a reference to the mc.
function Reproduction(mc){
this=mc;
//rest of you function blah blah

}

setInterval(Reproduction, 10000,this);
and the same for the other functions you have

or something like that.....

That worked. Thanks.
