I am getting this exception in logs
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'CCSprite is not using the same texture id'
What I am trying to do is adding a normal "myfile.png" file to a SpriteBatchNode
**declaration of batch node
CCSpriteBatchNode *_backgroundLayer = [CCSpriteBatchNode batchNodeWithFile:@"sprites.png"];
** usage
This line works perfect
CCSprite *sprite1 = [CCSprite spriteWithSpriteFrameName:@"PngFileKeptInSpriteSheet.png"];
[_backgroundLayer addChild:sprite1];
But, when I use a direct *.png file to add to batch node, It crashes
CCSprite *sprite2 = [CCSprite spriteWithFile:@"myfile.png"];
crashes on line
[_backgroundLayer addChild:sprite2];
On further debugging I found that:
The assertion failure is in file CCSpriteBatchNode.m
inside method -(void) addChild:(CCSprite*)child z:(NSInteger)z tag:(NSInteger) aTag
at line NSAssert( child.texture.name == textureAtlas_.texture.name, @"CCSprite is not using the same texture id");
P.S. : by "normal" I mean not taken from *.plist file
First and foremost, I'd update cocos2D. However, that isn't your problem and probably isn't "fixed" in the latest version anyway. This isn't really a bug
Batch nodes require that all the sprites that you intend to batch are using the same texture. When you load a sprite sheet, it uses one, large texture. When you call spriteWithFile, cocos2d creates a texture from that image.
It's rare that you'll want to create a batch node from a sprite using spriteWithFile. The only scenario I can think of is when you want to draw the same image many times. (Rather than many images from the same texture).
In short, what you are trying to do is unsupported and doesn't make much sense anyway as the two sprites wouldn't be batchable.
