Hi,  
I have duplicated a few bars and placed them on a MC (an image), trying to define each of these bars as a mask of the same MC. But it seems that only the last element of the array works as a mask. Can we define 10 bars to be a mask of the same MC?  
[AS]  
var bars = new Array();  
var n = 10;  
var num=0;  
gridx = bar.\_width;

for(i=0;i\<n;i++){  
\_root.bar.duplicateMovieClip(“bar”+num,num);  
mc = this[“bar”+num];  
mc.lag = num;  
mc.\_x=gridx\*i;  
mc.\_y=-320;  
bars[num] = mc;  
pic.setMask(bars[num]);  
num++;  
}  
[/AS]

any help on this, please?

Put all your bars into a mc and use that to mask.

Does the image become masked with this effect? I mean when the different bars come down at different times, does the different parts of the image appear under the mask?  
You know, I don’t have my .fla file here right now, therefore have to ask these questions.
