partial preloader help

[gooflett]

I found this code on the best of Kirupa and was wondering how I could modify this code to go to and play frame 2 after it has loaded a certain number of kilobytes or a certain percentage.

I would like it it to preload 1/4 of the total kb and then play. Currently it loads the whole enchilada.

Thanks for the help.


//here we are getting the total bytes and the number of
//bytes that have been loaded so far, of the movie, and
//dividing it by 1000 in order to come up with killobytes.
//we set two variables to be equal to these two statements
//like so
totalK=getBytesTotal()/1000;
loadedK=getBytesLoaded()/1000;
//remaining K is just the first variable, minus the second.
remainingK=totalK-loadedK;
//percentage of K loaded is just the second variable divided
//by the first, and then mutliplied by 100.
percentageK=(loadedK/totalK)*100;
//here we set the bar movie clip to scale, left/right by the
//amount of the percentage variable.
setProperty("bar",_xscale,percentageK);
//here is our break out.. if the amount of K loaded is greater
//than the total K of the movie, AND (that's what && means..
//both conditions have to be true) the total K is NOT equal to
//0, then goto the third frame.
if(loadedK>=totalK&&totalK!=0){
gotoAndPlay(3);
}

totalK is the total filesize of your SWF expressed in Kilobytes (by dividing it by 1000)
loadedK is the number of Kilobytes that has been loaded

totalK / 4 is the same as 25% of your total filesize. So you can change the last lines to:

if (loadedK >= (totalK / 4)) {
   gotoAndPlay(2);
}

For some reason that is not working. It loads 100% of the movie and then plays. What else do you think we could try? Why isn't flash dividing like it should?

You can download the file I am working on here. http://d01.megashares.com/dl/80ad611/loader.fla.zip

Typically, that kind of code has an instruction on frame 2 to go back to frame 1; that's how it manages to update the variables. So I doubt that you can break out to frame 2...try using another frame instead.

I think this is working. The only thing is it hangs on frame 2 for a second before it goes to frame 3. Not sure if there is a fix for this or not. But this helps a ton. Let me know if you have an idea why it might hang on frame 2.

Frame 1
//here we are getting the total bytes and the number of

//we set two variables to be equal to these two statements

//remaining K is just the first variable, minus the second.
remainingK=totalK-loadedK;
//percentage of K loaded is just the second variable divided
//by the first, and then mutliplied by 100.
percentageK=(loadedK/totalK)*100;
//here is our break out.. if the amount of K loaded is greater
//than the total K of the movie, AND (that's what && means..
//both conditions have to be true) the total K is NOT equal to
//0, then goto thesecond frame.
if (loadedK >= (totalK / 8)) {
gotoAndPlay(3);
}

Frame 2
gotoAndPlay(1);

Frame 3
The movie


Are you really in Antartica? If so... that is awesome!
