Loading appears to happen twice in preloader?

[jguthrie 1 Likes (Newbie)]

It seems that when my preloader loads the main swf, it loads it twice. The textfield that is used to report the progress starts at a random percentage, then goes up to 99, then resets to 0 and goes back up...

 

Any ideas on why this would occur? I was wondering if the initial call that LoaderMax makes to determine the size would cause this...

The reason I see the progress bar go up twice is:

 

PreloaderSwf (using LoaderMax) loads in MainSwf which in turn loads a video (using LoaderMax).

 

I had requireWithRoot set to true for the video. So what I was seeing was the loadermax class in the preloader swf, loading the Main swf, and then the video.

Yep, bingo. By the way, if you want to avoid that backwards jump, you can set the estimatedBytes on your SWFLoader to include the swf AND the video. Just an option.

I actually dont mind it in that I 'know' when the main.swf has finished loading and when loading the video has started.

 

Except I am finding out in an odd way. Since preloader.swf is using loadermax to only load in main.swf, I 'discover' when main.swf has loaded when a netstatus event of the video fires "NetStream.Play.Start" ...

 

It may be handy to have the preloader load the main.swf and the video but the video needs to play 'within' main.swf and I wasnt sure how to hand off the video loader to main.swf...

 

Any ideas for that?

I'm not quite sure what you mean by "hand off", but you can get the video from within the main.swf using the static LoaderMax.getLoader() method. Or pass the VideoLoader instance to a method in the main.swf. Lots of options actually.

[jguthrie 1 Likes (Newbie)]

Ya that's what I meant. As in the best way to preload the vid & main.swf in the preloader.swf but have the video play from within the main.swf. Could also target a movieclip in the main.swf by using the container param in vidloader.

 

thanks!
