Help!!!  
I am a newbie and need to create some falling snow in Actionscript 3.  
I know a little bit and have had a go at it myself.  
i used the lovely tutorial Falling snow 2.0 and tried to convert the code to AS3.

Maybe someone could have a look and tell me where i am going wrong?

there’s some code attached to the 1st frame of the main timeline and then some more attached to a movie clip. i’ve created a as class and linked it to the movie clip for as3.

Here’s the original code:  
as2 on 1st frame:

[FONT=Courier New][COLOR=Blue]for (k=0; k\<70; k++) {  
import flash.display.MovieClip;  
duplicateMovieClip(this.snow, “snow”+k, k);  
}

[FONT=Verdana][COLOR=Black]as3 [/COLOR][/FONT][/COLOR][/FONT]on 1st frame[FONT=Courier New][COLOR=Blue][FONT=Verdana][COLOR=Black]:  
[FONT=Courier New][COLOR=RoyalBlue]  
this.addEventListener(Event.ENTER\_FRAME, snowFlakes);

this.addEventListener(Event.ENTER\_FRAME, allTogether);

for (k=0; k\<70; k++) {  
import flash.display.MovieClip;  
duplicateMovieClip(this.snow, “snow”+k, k);  
}

[FONT=Courier New][COLOR=RoyalBlue]onClipEvent (load) {  
//specifies the size of the movie stage  
movieWidth = 720;  
movieHeight = 576;

```
//variables that will modify the falling snow
i = 1+Math.random()*2;
k = -Math.PI+Math.random()*Math.PI;

//giving each snowflake unique characteristics
this._xscale = this._yscale=50+Math.random()*100;
this._alpha = 75+Math.random()*100;
this._x = -10+Math.random()*movieWidth;
this._y = -10+Math.random()*movieHeight;

```

}  
onClipEvent (enterFrame) {  
//putting it all together  
rad += (k/180)\*Math.PI;  
this.\_x -= Math.cos(rad);  
this.\_y += i;  
if (this.\_y\>=movieHeight) {  
this.\_y = -5;  
}  
if ((this.\_x\>=movieWidth) || (this.\_x\<=0)) {  
this.\_x = -10+Math.random()\*movieWidth;  
this.\_y = -5;  
}

        }
    }
    

}
