Zoom in and out

1

I would like to zoom in a movieclip and after that zoom out. This I would like to happen randomized.

Right now it just zoom when I enter the frame.



this._xscale = this._xscale+1;
this._yscale = this._yscale+1;
if ((this._xscale >= 150) && this._yscale >= 150) {
this._xscale = 150;
this._yscale = 150;
