If i add a child to a parent(Sprite), set it's position at (0, 100). Then i rotate the parent by 90 degree. The child did rotate also 90 degree, but it's position is still at (0, 100), in my thought as a Flash developer ever, the child not only should rotate 90 degree, but also should move to (100, 0) position. It means rotation does not rotate the coordinate space?
Thanks, maybe this is a basic of the cocos2d-x, but i don't know yet!
