   Hi, It seems that I found a bug in setTextureRect in CCSprite class:

   -(void)setTextureRect:(CGRect)rect
   {
   	CGRect rectInPixels = CC_RECT_POINTS_TO_PIXELS( rect );
   	[self setTextureRectInPixels:rectInPixels rotated:NO untrimmedSize:rectInPixels.size];
   }

   The "rotated" should be "rectRotated_", not "NO", or you can not set sprite's texture rect correctly if the texture is set from a sprite frame which is rotated.

   Hi,

   I know this is an old thread - but is this a bug, or does CCSpriteFrameCache not support rotated sprites?

   I have a sound toggle button, where I switch the texture for a sprite (using a spritesheet made with TexturePacker - with "Allow rotation" enabled)

   To switch texture for my sprite, I'm using: (buttonSoundToggle is a CCSprite)
   

   CCSpriteFrame *newIcon = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:@"newSoundIcon.png"];
   [buttonSoundToggle setTextureRect:[newIcon rect]];

   My icon's is rotated in the spritesheet. If I try to change texture for a sprite, where to code in CCSprite is (aka. no change):
   

   [self setTextureRectInPixels: rectInPixels Rotated: NO untrimmedSize: rectInPixels.size];

   then the sprite appears just like it is in the spritesheet - rotated - which it wrong. But if I change the CCSprite code and use:
   

   [self setTextureRectInPixels: rectInPixels Rotated: rectRotated_ untrimmedSize: rectInPixels.size];

   The sprite is properly rotated.

   I do not like to change in CCSprite if I'm not sure that it is a bug. I can see that version 2.0 is still set it to NO

   Or do I switch the texture in a completely wrong way ?

   /Dan - using v. 1.0.1
