I’m writing a preloader to load external movie clips but my function doesn’t seem to be working properly. I call the function and it says that 100% is loaded and makes the movie clip thats showing the out put invisible…thats what supposed to happen except for the going to 100% straight away. the percent is being calculated properly but i think that the function is being executed before the new movie even starts to load…i’ve tried movieClip.onData but it doesn’t seem to work…
Well heres the code
```auto
function loader() {
percentClip._visible = true;
targetClip._visible = false;
percent = 0;
onEnterFrame = function () {
if (percent == 100) {
percentClip._visible = false;
targetClip._visible = true;
onEnterFrame = null;
}
percent = Math.floor(targetClip.getBytesLoaded()/targetClip.getBytesTotal())*100;
percentClip.textBox.text = "Movie is loading, "+percent+"% is loaded";
};
}
```
Ok thanks 🙂
