Hey all… does anybody know how hard it would be to make little movie clips that pulsate and change colour randomly? I wanna try and make a sorta disco ball effect :).

Cheers, Johnny

</div>

setInterval(randRange, 100, 100000, 999999);  
var mcColor = new Color(mc);  
function randRange(min:Number, max:Number) {  
var randomNum:Number = Math.round(Math.random()\*(max-min))+min;  
mcColor.setRGB(“0x”+randomNum);  
trace(randomNum);  
}

just place a movieClip and give it an instance name of “mc” on stage to test.  
hope this helps

p.s.  
to make it go faster adjust  
setInterval(randRange, THIS, 100000, 999999);

## in the last code : for (var i = 0; i\<20; i++) { mc.duplicateMovieClip(“mc”+i, this.getNextHighestDepth(), {\_x:mc.\_x+mc.\_width\*i, \_y:mc.\_y}); } I duplicate the one MC called “mc” and give it a new name of “mc”+i (e.g. mc0,mc1,mc2,mc3…upto mc19)

## then for (var i = 0; i\<20; i++) { var mcColor = new Color([“mc”+i]); var randomNum:Number = Math.round(Math.random()\*(max-min))+min; mcColor.setRGB(“0x”+randomNum); trace(randomNum); } I attach a new color object to each “mc”+i (mc0-mc19)called mcColor

so if you wanted to copy and paste an MC you have manually onto the stage and manually give them instance names of mc0,mc1,mc2…upto mc19  
the code would work as well

does this help?
