Atlas instead of sprites?

[Jirka1111]

Is using atlas instead of sprites a good approach? I have 6 sprites, but if I use Appgyver Steroids, framerate is really low and I think after I add some ads stripe it's gona be very laggy.

Yes always use an atlas as long as it's not too big (image dimensions, not file size)

So should I use it even for preload bar?

No because you need that to be available before the rest of your game assets are. If the preload bar is part of the same image the game sprites are in, you can't show it until they've all loaded. Which kind of defeats the purpose of a loading bar.

Yeah, that's right   What if I need to change my character sprite? Do I have to use kill() function and then game.add.sprite?

 

EDIT: Cannot set frameName: bird.png?

 

What the hell? Name is the same...

 

Preloader:

 

this.load.atlas('atlas', 'images/atlas.png', 'images/atlas.json');

 

Main state:

 

Bird.bird = this.add.sprite(Bird.GAME_WIDTH/3, Bird.GAME_HEIGHT/2, 'atlas');

Bird.bird.frameName = 'bird.png';

Try just 'bird' for the framename. Some tools strip the file extension from the frame names.

Actually I opened JSON file and there was bird.png. I use TexturePacker. Shoul I use JSON Array or JSON hash?

[CtlAltDel]

this.add.sprite(Bird.GAME_WIDTH/3, Bird.GAME_HEIGHT/2, 'atlas', 'bird.png');

 

it should work if your json is ok.

Thank you, that really works :-) But my fault was using JSON Hash instead of Array. Somebody should wrote it to proper example.
