make snow fall inside a movieclip

[iggyotis22]

Hi,

I have some code which makes snow fall perfectly, but I want it to only happen inside a movieclip (a snowglobe to be exact). Any ideas how I could make this happen?

var speed:Number = 5;
var total_snow:Number = 200;
var snow_per_second:Number = 3
var hit_target:MovieClip = gazing_mc
//
var holder:Sprite = new Sprite();
var target_shake:Boolean = false;
//
addChild(holder);
//
hit_target.mainX=hit_target.x;
hit_target.mainY=hit_target.y;
//
function createSnow() {
var snow:MovieClip = new MovieClip();
snow.graphics.beginFill(0xFFFFFF);
snow.graphics.drawCircle(0,0,Math.random()*2);
reset(snow);
addBlur(snow);
snow.addEventListener(Event.ENTER_FRAME,fall);
holder.addChild(snow);
}
function reset(s:MovieClip) {
s.hit=s.shake=false;
s.y=0;
s.x=Math.random()*800;
s.xspeed=Math.random()*speed-(speed/2);
s.yspeed=Math.random()*speed+1;
}
function init(e:Event) {
for(var i=0; i<snow_per_second; i++) {
createSnow();
}
snow_id++;
if(snow_id>total_snow) {
removeEventListener(Event.ENTER_FRAME,init);
}
}
function addBlur(s:MovieClip) {
var blurX:Number = Math.random()*2+3;
var blurY:Number = Math.random()*2+3;
var filter:BitmapFilter = new BlurFilter(blurX, blurY, BitmapFilterQuality.LOW);
var myFilters:Array = new Array();
myFilters.push(filter);
s.filters = myFilters;
}
function fall(e:Event) {
if (!e.target.hit) {
e.target.x+=e.target.xspeed;
e.target.y+=e.target.yspeed;
if (e.target.y>600) {
reset(MovieClip(e.target));
}
if(!e.target.shake) {
if (hit_target.hitTestPoint(e.target.x,e.target.y,tru e)) {
e.target.hit=true;
}
}
}else{
if(target_shake) {
e.target.hit=false
e.target.shake=true;
}
}
}
function shake_int(e:TimerEvent) {
hit_target.x=hit_target.mainX+Math.random()*5-2.5;
hit_target.y=hit_target.mainY+Math.random()*5-2.5;
}
var shake_timer:Timer = new Timer(2,100);
shake_timer.addEventListener(TimerEvent.TIMER,shak e_int);
shake_timer.addEventListener(TimerEvent.TIMER_COMP LETE,shake_fnish);
function shake_fnish(e:TimerEvent) {
target_shake=false;
}
//
hit_target.addEventListener(MouseEvent.CLICK,shake _start);
function shake_start(e:Event) {
target_shake=true;
shake_timer.reset();
shake_timer.start();
}
//
var snow_id:int = 0
addEventListener(Event.ENTER_FRAME,init);

For keeping it inside the visible area of the globe you should apply a mask to it.
