   I had this working completely fine, I tried to adjust some things and now it won't even play. Not sure what the issue is, but I can't see anything wrong with my code. Hopefully somebody else can or has at least experienced something like this before.

   Here is my code:

   '
   //holder for animation to run in
   Sprite * holder = [[Sprite alloc] initWithFile:@"aurora0010.png"];
   holder.transformAnchor = ccp(240,320);
   [holder setPosition:ccp(240,320)];
   [self addChild:holder z:2 tag:99];

   //animation creation
   Animation * next = [[Animation alloc] initWithName:@"next" delay:0.1];
   for(int i = 10; i <= 110; i++){
   NSLog(@"add frame");
   [next addFrameWithFilename:[NSString stringWithFormat:@"aurora%04d.png", i]];
   i++;
   i++;
   //i++s are because I removed every 2nd and 3rd frame to use way less memory
   }

   //run that shit
   id animate = [Animate actionWithAnimation:next];

   [holder runAction:animate];

   The holder sprite is shown on the screen with the initial image of the animation, but nothing happens after that.

   Just some more info, I've tried cleaning all builds, rebooting my computer, running on simulator and device. After a while I copied the exact code from a copy thats 2 days old (when it was working fine) and still the same result.

   All of the frames are loaded (according to NSLog).

   No idea whats wrong...

   Probably not related to your problem, but this line looks strange to me:

   [next addFrameWithFilename:[NSString stringWithFormat:@"aurora%04d.png", i]];

   What does the '04' represent between the '%' and the 'd'?

   It forces it to have 4 digits, with 0s added to make the 4 digits I believe

   so if i=10 the file name is aurora0010.png

   i = 103, file name is aurora0103.png

   Wow - that's pretty handy. Thanks.

   Do you have another NSLog other than @"add frame" - something that tells you exactly what's been loaded? Right now, the current log will be called whether or not the code directly following works or not.

   Are you positive you added the aurora####.png files to your project and they are included in your app. Are they in their own folder?

   Umm, I added this line:
   NSLog([NSString stringWithFormat:@"numframes: %i", (int)[[next frames] count]]);

   And it gives a frame count of 34 (which should be right)

   In the project folder on the hard-drive they are all in the base folder along with the Xcode project and all the other Resources.
   Within Xcode, they are within a subfolder of Resources (as are all other resources for organization purposes).

   I took out everything from the layer and just added:
   '[self schedule:@selector(testing) interval:0.5];'

   Then in testing I have:
   '-(void)testing{
   NSLog(@"testing");
   }'

   But this doesn't even work. So something is getting messed up somewhere. The previous scene has animations that all work fine, and the next scene has a scheduled task that also works fine. No idea why this could go wrong.

   Entire code for the layer is now:
   '-(id) init{
   self = [super init];

   if (self != nil) {
   [self schedule:@selector(testing) interval:0.5];
   }

   return self;
   }

   -(void)testing{
   NSLog(@"testing");
   }
   '

   Scene class is pretty much the same, initializes the layer and adds it.

   Ugh, I'm such a moron.

   Had implemented an onEnter method in a super class and forgot [super onEnter];
