Add assets to load during create()

[xompl]

Hi,

 

I was trying to minimize the total loading time so I wanted to load some assets such as the credits music in background during the game.

 

What I did is to add the assets to the queue during of the main meni create() instead of during the preload state. I had to start the loader myself.

 

 

      this.game.load.audio('music_credits', ['assets/music_credits.mp3', 'assets/music_credits.ogg']);
      this.load.start();

 

This totally works, it loads the music in parallel with the main menu execution and later I can play it in the credits state but I get the following

console errors when I execute the start():

 

Chrome:

Uncaught TypeError: Cannot read property 'x' of null

 

Firefox:

TypeError: this._frame is null

 

Am I doing it wrong? Any sugestion?

 

Thanks!

Did you previously use a preloadSprite? If so I think it might be this - set preloadSprite to be nothing and I think it may go away.

Thank you! The error went away with

 

this.load.preloadSprite = null;

 

I still need to study the performance implications of loading in background...

 

Thanks

Loading itself should be ok, but if the audio file needs decoding (for example mp3s do) then it will hammer the CPU while it does that, freezing up everything else.

Hi rich,

 

At least on Linux with both Chrome and Firefox I don't notice any slowdown, maybe it has its own decoding thread. but I haven't tested on mobile devices yet.

This sounds pretty neat. My game is a little slow to load, might try this out.
