A simple topic i’m breaking my head about…

I’m creating a complex site, with lots of calculations, while I have to keep it as light as possible. I don’t want to have 50 [color=slategray].onEnterFrame[/color][color=black]'s[/color] running simultaniously, so, how do I stop them? See example:

Let’s say I want a simple movement, invoked by some reason:

```auto
 
 
mcChild.onEnterFrame = function(){
if(mcChild._x < mcParent._width){
mcChild._x += 5;
}
}

```

Now I want to stop the [color=slategray].onEnterFrame[/color] check, because it reached the [color=slategray]if = false[/color][color=black] - How??[/color]

Cheers
