Flash Actionscript in MX2004

[Jay_Stealth]

ok i've designed a flash movie with one layer with a movie clip which is a snowflake with this code

onClipEvent(load) {
	this._x = Math.random()*200 // 0 to 200
	this._y = Math.random()*200 // 0 to 200
	speed = Math.random()*3+3; // 3 to 6
	drift = Math.random()*2-1; // -1 to 1
	rotate = Math.random()*6-3; // -3 to 3
}
onClipEvent(enterFrame) {
	this._y += speed;
	this._x += drift;
	this._rotation += rotate;

	//bring back to top
	if (this._y > 200) this._y =0;
  
  //one side to another
  if (this._x < 0) this._x = 200;
  if (this._x > 200) this._x = 0;
}
  

on the root layer i have this code

MovieClip.prototype.randomRGB = function(){//adds a random RGB to the movie clip
	(new Color(this)).setRGB(Math.random()*0xFFFFFF);
}
snowflake.onEnterFrame = this.randomRGB;
//creating a key listener. The movie response to the hit of the spacebar. Hitting the spacebar triggers an event
spaceBar = new Object();

spaceBar.onKeyDown = function(){

	if (Key.getCode() == 32){//32 is the number that corresponds to the spacebar.
  
  randomRGB;// this changes the size of the grid for the duplicated movieclip.
	}
}

Key.addListener(spaceBar);//this registers the 'spaceBar' to receive key event onKeyDown.

// create 30 snowflakes
for(var i=0;i<30;i++) {
	snowflake.duplicateMovieClip("snowflake"+i,i);
}

However it doesnt work how i want it to. I want the movie clip to listen to the spacebar and when pressed all of the snowflakes change to a random colour.

Here is the .fla

Anything would be appreciated. Thanks
