   Hi everyone,

   I am having a real hard time with an error in my game.
   After loading all textures I need in my main scene and playing for a while I get the "can't add image: in CCTextureCache" in the middle of my game and textures are not drawn anymore.
   If I don't preload the images I get the same error.
   How can CCTextureCache miss an already loaded texture???
   Can it be a problem of Memory??? I am not receiving any memory warning in my delegate.

   The code where i call the sprites is the following. I do this everytime I need a new Block in my game. Block is a subclass of CCSprite.

   In Block.m:

   Block *block = [CCSprite spriteWithFile:file];
   [self addChild:block];

   In MainSceneLayer.m after block collides I draw a new one.

   waitBlock = [Block node];
   [self addChild:waitBlock];

   Can anyone help me please. I have looked everywhere but I don't know how can it be that CCTextureCache don't find a texture.
   Is there a limit on CCTextureCache??? I make a cleanup after every Block that disappears from game also.

   Thank you for the help!!!

   Block *block = [CCSprite spriteWithFile:file];

   im asuming that this actually reads something like..

   Block *block = [CCSprite spriteWithFile:@"block.png"];

   Without seeing the full code its kinda hard to see whats goin on

   I do something like this for every block in block.m

   NSMutableString *file = [[NSMutableString alloc] init];
   if([GameManager sharedGameManager].world == 1)
   [file appendString:@"selva_"];
   else if([GameManager sharedGameManager].world == 2)
   [file appendString:@"desierto_"];
   else if([GameManager sharedGameManager].world == 3)
   [file appendString:@"volcan_"];
   else if([GameManager sharedGameManager].world == 4)
   [file appendString:@"hielo_"];
   else if([GameManager sharedGameManager].world == 5)
   [file appendString:@"mar_"];
   else
   [file appendString:@"futuro_"];

   // Initialize block
   [file appendString:@"vacio.png"];
   Block *block = [CCSprite spriteWithFile:file];
   block.scale = 0.74f;
   self.tag = 7;
   [GameManager sharedGameManager].emptyBlockCount--;
   [self addChild:block];

   return self;

   In MainScene.m something like this when block collides I add a new one

   if([GameManager sharedGameManager].world == 5)
   waitBlock.position = ccp(42.5f + currentBlock.blockSize*2.5f, 0.0f);
   else
   waitBlock.position = ccp(42.5f + currentBlock.blockSize*2.5f, 55.0f + 7*currentBlock.blockSize);
   waitBlock.scale = 1.0f;
   waitBlock.rotation = 0;
   waitBlock.wait = NO;
   currentBlock = waitBlock;
   waitBlock = [Block node];
   waitBlock.position = ccp(274, 437);
   waitBlock.scale = 1.21f;
   waitBlock.rotation = 4;
   [self addChild:waitBlock];

   And after playing for a while, waitBlock tries to get the texture from CCTextureCache and it says image is NULL.

   Do u need any more code???
   MainScene is huge.

   Thanks again.

   waitBlock = [[Block node] retain]; maybe?

   but of course I would probably NSLog the image name...

   ill look again more closely later, but at first glance at your if else chain, OUCH!

   NSMutableString *file = [[NSMutableString alloc] init];
   if([GameManager sharedGameManager].world == 1)
   [file appendString:@"selva_"];
   else if([GameManager sharedGameManager].world == 2)
   [file appendString:@"desierto_"];
   else if([GameManager sharedGameManager].world == 3)
   [file appendString:@"volcan_"];
   else if([GameManager sharedGameManager].world == 4)
   [file appendString:@"hielo_"];
   else if([GameManager sharedGameManager].world == 5)
   [file appendString:@"mar_"];
   else
   [file appendString:@"futuro_"];

   use a switch dude!

   NSMutableString *file = [[NSMutableString alloc] init];
   switch ([GameManager sharedGameManager].world) {
   case 1: {
   [file appendString:@"selva_"];
   } break;
   case 2: {
   [file appendString:@"desierto_"];
   } break;
   }
   etc etc etc

   I'm still stumped at the first line of code in the first post
   

   Block *block = [CCSprite spriteWithFile:file];

   How can a block be a CCSprite?

   And then I see
   

   NSMutableString *file = [[NSMutableString alloc] init];

   But no release at any point afterwards.
