Putting this code in the first frame of your animation will allow you to drag circles on the scene. Fun!

```
MovieClip.prototype.drawCircle = function(r, x, y){
this.moveTo(x+r, y);
this.curveTo(r+x, -0.4142*r+y, 0.7071*r+x, -0.7071*r+y);
this.curveTo(0.4142*r+x, -r+y, x, -r+y);
this.curveTo(-0.4142*r+x, -r+y, -0.7071*r+x, -0.7071*r+y);
this.curveTo(-r+x, -0.4142*r+y, -r+x, y);
this.curveTo(-r+x, 0.4142*r+y, -0.7071*r+x, 0.7071*r+y);
this.curveTo(-0.4142*r+x, r+y, x, r+y);
this.curveTo(0.4142*r+x, r+y, 0.7071*r+x, 0.7071*r+y);
this.curveTo(r+x, 0.4142*r+y, r+x, y);
}
_root.lineStyle(2,0x000000,100);
_root.onMouseDown=function(){
x=_xmouse;
y=_ymouse;
}
_root.onMouseUp=function(){
var dx=_xmouse-x;
var dy=_ymouse-y;
this.drawCircle(Math.sqrt(dx*dx+dy*dy),x,y);
}
```
