Hi Im using a for in loop to grab the names of my mc on the \_root timeline and push() them into an array named bricks. i then use a prototype function fade them in one at a time. The problem is that it only works to a piont and then stops.

I thought posible causes could be the time it takes to build the array as i do have 713 mc on my timeline.

this is my code i tried attaching the fla but its to big

fadespeed = 9;  
function init(){  
brick = new Array();  
for(var prop in \_root){  
if(typeof \_root[prop] ==“movieclip”){  
brick.push(\_root[prop]);  
}  
for( var i = 0; i\<brick.length; i++) {  
brick\*.\_alpha = 0;  
brick\*.id = i;  
}  
brick[0].fade();  
}  
}  
MovieClip.prototype.fade = function() {  
this.go = true;  
this.onEnterFrame = function() {  
this.\_alpha += fadespeed;  
if (this.go) {  
if (this.\_alpha\<50) {  
this.go = false;  
brick[this.id+1].fade();  
}  
}  
if (this.\_alpha\>=100) {  
delete this.onEnterFrame;  
}  
};  
};  
init();

thank you

I don`t think that there is anything wrong with your code,its just too much to do. I tried this which is basically the same  
brick = ;  
fadespeed = 2;  
for (var i = 0; i\<100; i++) {  
myclip = attachmovie(“mc”, “mc”+i, i);  
myclip.\_x = random(700);  
myclip.\_y = random(500);  
myclip.id = i;  
myclip.\_alpha = 0;  
brick.push(myclip);  
}  
MovieClip.prototype.fade = function() {  
this.go = true;  
this.onEnterFrame = function() {  
this.\_alpha += fadespeed;  
if (this.go) {  
if (this.\_alpha\<50) {  
this.go = false;  
brick[this.id+1].fade();  
}  
}  
if (this.\_alpha\>=100) {  
delete this.onEnterFrame;  
}  
};  
};  
brick[0].fade();

worked fine for 100 but broke down for 700.Varying transparency is really hard on processor too
