How to duplicate moveclip automatically?

programming flash
1

Hello,

In my flash file, I have a movieclip called target and one button used to
duplicate the target movieclip.

the actionscript of movieclip is
[AS]
onClipEvent (load) {

scale = (random(100) + 50)

this._x = random(550);
this._y = random(400);
this._alpha = random(100);
this._xscale = scale;
this._yscale = scale;

}
[/AS]

[AS]
the actionscript of button is
i = i + 1;
duplicateMovieClip (_root.target, “target” + i, i);
[/AS]

I would like to duplicate movieclip(target) automatically means I don’t have to press button to duplicate movieclip.

Any ideas?

I am really appreciate your help.
