Ok, I asked a similar question yesterday but for some reason when I post a topic and set it to my favorites it's automatically a link back to the front of the forum??

Anyways, this is a simpler question, (where "cube.png" is a 16x16 square image)
```
Sprite *s = [Sprite spriteWithFile:@"cube.png"];
CGPoint prePos = [s convertToWorldSpace:CGPointZero];

[gTouchPiece setRotation:(float)[(CocosNode *)s rotation]+90];

CGPoint postPos = [s convertToWorldSpace:CGPointZero];
```
This will produce different values for prePos and postPos but the object is not moving and its anchor is in the middle?

Any help or suggestion as to how to adjust postPos would be a big help, thanks!

Yeah I finally realized that it was tracking the corner of the box and needed to convert [s transformAnchor] instead.

This' off topic but I tried to make a followup explaining how I fixed this yesterday but (this happens everytime I post anything) the server comes back saying "thread cancelled" or when I post a new thread i get a dead link when i try to bookmark it.Am doin something wrong? Or is anybody else having this problem?

"Or is anybody else having this problem?"

Ive never got a "thread cancelled" error! I use the web interface tho, are you using the email interface?
