Sorry for cross-posting, but I’m in bit of a jam.

I’m trying to preload a dynamic mp3 and show the percentage loaded as a number and a graphic bar. But it’s not working.

The following code is on the the movie clip that the mp3 is being loaded into.

* * *

onClipEvent (load) {  
mySound = new Sound();  
mySound.loadSound(“music.mp3”, false);  
}

onClipEvent (enterFrame) {  
downloaded = mySound.getBytesLoaded();  
total = mySound.getBytesTotal();  
percent -= (percent-((downloaded/total)_100))_.25;  
per = int(percent);  
percentage = per+"%";  
loadBar.\_width = per;

if (percent\>99) {  
\_root.gotoAndPlay(“intro”);  
}  
}

* * *

Thanks.

> You want to calculate the percent loaded but the first line got’s nothing to do with percents…  
> I think the following could help you out:

percent = downloaded / total;  
// this isn’t percent either but I don’t know the English word for it  
percentage = Math.round(percent \* 100) + “%”;  
loadBar.\_width = percent \* totalWidthOfBar;

You need to replace the totalWidthOfBar with the acording variable 🙂

Oh, by the way. This also means that you need to change your check for when to start. When (percent == 1) the movie is fully loaded (as it’s the actual percent divided by 100).

Thanks for your help. But I have to admit, I’m still a newbie at this. I’ll do as you suggested. But I can’t help feeling a little lost.
