SKTextureAtlas how to load textures in order

Question

I've using a SKTextureAtlas (.atlas folder) to store the frames for an animation I'm using. I've numbered the frames like frame.1.png, frame.2.png, etc - there are 10 frames in total. I noticed my animation looks horrible even though the frames previewed in my graphics program look great. I NSLoged out and found that it is loading the atlas in random order! I assumed it would at least follow the bundle file order. How do I get it to use the bundle order without sorting the array myself. Also do I put the @2x images in with the rest of them or do I create a separate atlas? ``` SKTextureAtlas *sleighAtlas = [SKTextureAtlas atlasNamed:@"sleigh"]; NSArray *textureNames = [sleighAtlas textureNames]; NSMutableArray *sleighTextures = [NSMutableArray new]; for (NSString *name in textureNames) { NSLog(@"texture: %@",name); SKTexture *texture = [sleighAtlas textureNamed:name]; [sleighTextures addObject:texture]; } ``` Its printing out: 2013-12-04 09:56:54.407 Santa Game[41611:70b] texture: sant…

Accepted Answer

Probably `textureNames` property contains texture names unordered. Instead of using fast enumeration use `for(;;)`:

```
for (int i=0; i < sleighAtlas.textureNames.count; i++) {
    NSString *textureName = [NSString stringWithFormat:@"santaAndSleigh.%d", i];
    [sleighTextures addObject:[explosion2Atlas textureNamed:textureName]];
}
```

Though this method would probably not work if you put @2x images into `sleighAtlas`.
