the thing is like this.I have 2 swf files which are loaded in the main swf.How can i make a preloader for them inside the main swf to display how much of the other swf has been loaded?Without adding a second scene…I was thinking about a dynamic text field that should display how much has been loaded for each movie.Unfortunately i don’t know how to da that.I have tried the code like this but it doesn’t work:  
per\_fractal = Math.Floor(getbytesloaded(fractal.swf)\*getbytestotal(fractal.swf)/100);  
Myoutput.text = “per\_fractal” + " %";

the script is like this:

but.onPress = function () {  
\_root.createEmptyMovieClip(“container”,1);  
loadMovie(“fractal.swf”,“container”);  
container.\_x = -50 ;  
container.\_y = 285.9;  
container.\_alpha = 0;

}

accel = container.\_alpha + 1/2;  
onEnterFrame = function() {  
container.\_alpha = container.\_alpha + accel;   
}

but2.onPress = function(){  
\_root.createEmptyMovieClip(“container”,1);  
loadMovie(“face.swf”,“container”);  
container.\_x = -50 ;  
container.\_y = 285.9;  
container.\_x = 170;  
container.\_y = 232;  
container.\_alpha = 0;  
}

Ok … I haven’t tried this but now that I think about it, this should work:

1. In the movie you want to display a preloader for on the host swf, make two extra keyframes at the very beginning of the timeline (frame 1&2).

2. To the first keyframe, add a new mc (CTRL+F8, don’t forget to drag it from the library onto the stage after using CTRL+F8) and apply following code to it (to the mc that is, not the keyframe):

[AS]onClipEvent(enterFrame){  
\_root.extloaded = \_parent.getBytesLoaded();  
\_root.exttotal = \_parent.getBytesTotal();  
if (\_root.continue == true){  
gotoAndPlay(frametostartmovieat);  
}  
}[/AS]

1. To the second keyframe, add this as:

[AS]gotoAndPlay(1);[/AS]

1. Now for your host movie. I suggest you use a preloader from the tutorial here on kirupa. It’ll make it easier to understand what’s going on. Find it [here](http://www.kirupa.com/developer/mx/percentagepreloader.htm)When you’re done setting it up, replace the code with this:

[AS]getPercent = \_root.extloaded/\_root.exttotal;  
this.loadBar.\_width = getPercent_widthofyourloadbar;  
this.loadText = Math.round(getPercent_100)+" %":  
if (\_root.extloaded == \_root.exttotal){  
\_root.continue = true;  
this.gotoAndPlay(3);  
}[/AS]

That should do it. If it doesn’t, please pm or mail me and I will check to see what’s wrong.

well,i don’t have time to see if it work right now couse i’m on my way home(after a long night at work) but i’ll try it first time in the morning.Anyway it’s quite easy to make it with keyframes but my problem is that i have made the movie in such a way that if i add keyframes my code will not work…  
thanks anyway
