There's a WAY easier way you could do this
By using _xscale: check this out:
1)make a bar-shaped movieclip
2)make the bar's outline
3)put this code in the bar:
onClipEvent(enterFrame){
loaded = _root.getBytesLoaded()
total = _root.getBytesTotal()
_xscale = (loaded/total)*100
if(_xscale >= 100){
//whatever you want it to do once its done
}
}
THAT way you dont have to make 100 frames, flash just scales the bar automatically.
