Stop movie clip

Question

I found some code on the web for confetti. The actual Movie
clip is just one small dot. in the Scene you place action script to
create the confetti effect. But you don't move the movie clip (dot)
itself into the Scene.
I can't figure out how to stop it at a certain point when I
no longer want it. I've tried various combinations of stop();
gotoAndStop(target or frame #). I've tried putting it in the
actionscript that creates the confetti effect, in the moviie clip
timeline and alone in the main tiimeline.
nothing is working.
any help would be appreciated. thank you.

Answer 1

Thank you but that didn't work either. Below is the code. On
the sample I found, it included only this code in the Timeline on a
layer called actions, and the moveclip in the library; the movie
clip is not in the timeline. and it works. it just doesn't stop.
screen_width=800
screen_height=200
frecuency=0//<< INCREASE NUMBER TO REDUCE PAPERS
QUANTITY
MovieClip.prototype.serConfeti=function () {
this._x=Math.ceil(Math.random()*screen_width)
this._xscale=Math.ceil(Math.random()*screen_height)
this._yscale=this._xscale
this.mover()
this.coloreame()
function getPorcentaje() {
var numero=Math.ceil(Math.random()*100)
return numero
function getOffset() {
var numero=Math.ceil(Math.random()*255)
var buleano=Math.round(Math.random()*1)
if (buleano==1) {
numero=numero*1
return numero
MovieClip.prototype.coloreame=function () {
var my_color=new Color(this)
var nuevo_color= new Object()
nuevo_color.ra=getPorcentaje()
nuevo_color.rb=getOffset()
nuevo_color.ga=getPorcentaje()
nuevo_color.gb=getOffset()
nuevo_color.ba=getPorcentaje()
nuevo_color.bb=getOffset()
my_color.setTransform(nuevo_color)
MovieClip.prototype.mover=function () {
this.onEnterFrame=function () {
if (this._y<600) {
this._y+=10
this._xscale=Math.random()*200
this._rotation=Math.random()*360
} else {
this.removeMovieClip()
MovieClip.prototype.caidaConfeti=function () {
this.createEmptyMovieClip("caida_mc",1)
var count=0
var confCount=1
this.caida_mc.onEnterFrame=function () {
if(count<frecuency){
count++
} else {
this.attachMovie("conf","conf"+confCount,confCount)
eval("this.caida_mc.conf"+confCount).serConfeti()
count=1
confCount++
_root.caidaConfeti();
// in this case this represents _root.
// so, if You want to use the caidaConfeti() prototype into a
MovieClip
// yo can do this for example:
MyMovieClip.caidaConfeti()
