Hi,  
I’m trying to use a prototype function from [http://proto.layer51.com](http://proto.layer51.com)  
this is the code  
[AS]  
MovieClip.prototype.slideShrinkRotateTo$checkProgress = function() {  
if (Math.abs(eval(“this.”+this.checkProperty)) \< 0.1) {  
this.\_parent.\_y = this.y;  
this.\_parent.\_x = this.x;  
this.\_parent.\_xscale = this.\_parent.\_yscale = this.es;  
this.\_parent.\_rotation = this.er;  
clearInterval(this.interval);  
this.broadcastMessage(“clipIsGone”, this.\_parent);  
this.removeMovieClip();  
}  
}  
[/AS]  
usage:  
[AS]  
MovieClip.slideShrinkRotateTo(newX, newY, newScale, newRotation, friction);  
[/AS]  
I’ve put this code in frame 1 in layer 1.  
In layer 2 frame 1 I’ve made a simple square (MC) with the instance square. and I write in frame 1  
[AS]  
square.slideShrinkRotateTo(400, 250, 200, 0, 0);  
[/AS]  
Problem: Nothing happens.  
What’s the problem here?

Problem is solved. It was the wrong value of speed.
