Can someone tell me how to cimbine the prototype with onEnterFrame. I’d like to fade in some objects like this:

[AS]

mc.\_alpha = 0  
onEnterFrame = function () {  
if (mc.\_alpha\<101) {  
mc.\_alpha = Math.round(mc.\_alpha+6)  
trace(mc.\_alpha);  
}  
mc.\_y = Math.round((mc.\_y+12)\*0.9)  
}

[/AS]

or can it be done without onEnterframe with an interval or something like that?

hope someone can help me out
