   Hi,

   Currently sprite dimension is tied closely to the dimension of the texture i.e. if I have png 64x64 pixels then CCSprite created from that texture will have such contentSize. It's only possible to scale the sprite to change this. Changing contentSize property (which is writeable for some reason) does not make any change (unless you don't see debug frame drawn). It would be very handy to have control on texture coordinates and sprite dimensions before transformations.. just wonder whether current behavior is intentional (contentSize change ignored) or it's kind of issue?

   Hi jotel,

   I also would have assumed contentSize was readonly -- perhaps it's just writeable so that the other cocos2d classes can set it internally.

   This is from CCNode.h:

   The untransformed size of the node.
   The contentSize remains the same no matter the node is scaled or rotated.
   All nodes has a size. Layer and Scene has the same size of the screen.

   I tend to think of contentSize for sprites as texture dimensions as well. I think what you are wanting to do must be available via some other route (setting texture coordinates -- perhaps you're looking for the rect param of the sprite init methods?). I doubt this is an issue.

   I tried everything with no luck :( The following method would be nice if worked

   
- (void) setTextureRect:(CGRect)rect untrimmedSize:(CGSize)size


   so rect would set the texture coordinates (which pixels from image should be taken to render sprite), and size would be used for the size of the sprite i.e. the rectangle of size size would be filled with pixels from texture.
