Preloader for External Swfs

[noelle88]

Does anyone know how to do this? I am loading two external swf files into holders on a main swf. I have a preloader on the main swf and on the swf I'm calling in. When I query holder2.getBytesLoaded() on the calling (main) swf, I get NaN. The preloader in the external swf doesn't show until it's loaded.. Help!

Im pretty sure that getBytesLoaded() only works when you load a clip on another level not into a holder clip.
someone may want to confirm this.

To use a preloader on an externally loaded swf, the preloader has to be in that swf, not the main movie. Then it works as a normal preloader. If the main preloader is not in it's own scene, there may be a problem. On the other hand, I have only used simple ifFrameLoaded preloaders on the external swf's I tried it on.

I tried to place the preloader on the externally loaded swf, but it doesn't show until the whole swf is loaded, showing '100% loaded of xxK' all at once after a long wait with no indication of loading.. ugh.

From my understanding, you can use GetBytesLoaded and GetBytesTotal with any object, i.e., [myObject].GetBytesLoaded.. etc. So I am attempting MyHolderMC.GetBytesLoaded, which seems to be working, except that it is not streaming - just going from 0K to 100K in one fell swoop. Is there anything obvious I'm missing..?

function checkLoad(){

var lBytes = main_holder2.getBytesLoaded();

var tBytes = main_holder2.getBytesTotal();

var percentLoaded = Math.floor((lBytes/tBytes)*100);

_level0.main_loader.bar._xscale = percentLoaded;

_level0.main_loader.percent.text = percentLoaded + "% of " + Math.floor(tBytes/1024) + "K loaded.";

if (lBytes>=tBytes && tBytes>0) {

if (count>=12) {

clearInterval(checkProgress);

main_holder2.gotoAndPlay("intro_play");

} else {

count++;
}
}

updateAfterEvent();
}

checkProgress = setInterval(checkLoad, 50);

main_holder2.stop();

getBytesLoaded() & getBytesTotal() will work from anywhere if correctly coded. You should post your preloading code or your .flas, so that we can have a look at the code.
Do you use components or linkage on the first frame in those movies?

In any case you could try my preloader in this thread:

Rid you present movie of it's own preloader!

Ahh, sweet victory! I got it worked out, hope it helps someone - below preloader script to track loading of external swf. Below code resides on main swf, calling external swf into a MC holder (main_holder2):

function checkLoad(){

var lBytes = main_holder2.getBytesLoaded();

var tBytes = main_holder2.getBytesTotal();

var percentLoaded = Math.floor((lBytes/tBytes)*100);

_level0.main_loader.bar._xscale = percentLoaded;

_level0.main_loader.percent.text = percentLoaded + "% of " + Math.floor(tBytes/1024) + "K loaded.";

if (lBytes>=tBytes && tBytes>0) {

if (count>=12) {

clearInterval(checkProgress);

_level0.main_holder2.nextFrame;
_level0.main_loader._visible = false;

} else {
}
}

_level0.main_holder2.updateAfterEvent();
}

checkProgress = setInterval(checkLoad, 50);

_level0.main_holder2.stop();
