   Hi
   I am trying to move and rotate a layer but I am having a problem. I can change the position of the layer but if I change the anchor point, rotate the layer and then tell it to move up it doesn't. Instead it moves at an angle.
   If I don't change the anchor point the layer moves up normally but subsequent rotations happen at the anchor point which is off screen. I want the rotation to happen at a certain point on screen. Why changing the anchor point changes the direction the layer moves?
   Thanks for any help.

   "Why changing the anchor point changes the direction the layer moves" bc its frame of reference has changed. Its still moving "up" to it.

   Suggestion: Create a 1st CocosNode, put your 2nd CocosNode inside the first. Move the 1st when you want to offset, rotate the 2nd when you want to rotate. Will that work?

   The node I use for rotation ignores the anchor point change. Although the anchor point changed, the rotation takes place at the initial position.

   The anchor point changes correctly on the first layer. Its child (CocosNode) ignores the new anchor point. Is this a bug?

   I think the bug is still in the latest version (0.99.5).
   Some body fixed that?
