AS3 Unloading external SWF piling up problem

Report · Jun 24, 2014

I have two buttons on main SWF what loads and Unload two external SWFs back and forth.

Also one timer function is calling external Screen saver SWF and unload the existing one when no interaction found.

I am using unloadAndStop() function to unload the external SWFs.

But after loading and unloading external SWFs, I am facing piling up or stack overflow problem.

Any help will be highly appreciated.

Thanks

apply unloadAndStop() to all your loaders just prior to executing all loads:

function unloadAllF():void{

if(loader1.content){

loader1.unloadAndStop();

}

//etc

}

Thanks Kglad for your time and quick reply.

I have just tried this, but due to limited knowledge of AS3 I am sure I am doing something wrong.

can you please explain in the code above where and how should I apply this function?

you need to add all your loaders to unloadAllF and you need to remove the other unloadAndStops.

Report · Jun 25, 2014

I have tried as suggested, applied unloadAllF prior to all loaders and call this function inside the button function just before loader and removed all other unloadAndStops, but still problem is there.

Also then added all loaders inside unloadAllF function but no success.

Is there something I have to stop, remove or unload from loaded SWFs first?

that looks good.

now make sure that code only executes once. ie, it's not in a frame that repeatedly executes.
