Hey there,  
I’m trying to fill a movieclip with a seamless pattern, so in essense its pretty much the same as Kirupa’s Duplicate Background tutorial. I’m having trouble converting the AS from filling the background to filling a movieclip

Here’s the original code:  
[AS]tileBG = function () {  
tile\_width = 34;  
tile\_height = 34;  
//  
x\_max = Math.round(Stage.width/tile\_width);  
y\_max = Math.round(Stage.height/tile\_height);  
trace(x\_max);  
trace(y\_max);  
for (x=0; x\<=x\_max; x++) {  
for (y=0; y\<=y\_max; y++) {  
bg = \_root.attachMovie(“square”, “bg”+x+y, this.getNextHighestDepth());  
bg.\_x = tile\_width_x;  
bg.\_y = tile\_height_y;  
}  
}  
};  
tileBG();[/AS]

I’ve tried replacing \_root with the name of my clip, but that didn’t seem to do the trick, if anyone can point me in the right direction I’d appreciate it 🙂
