In the above case the texture is now centered with its lower left corner over the node's position. You can no longer rely on the position of the sprite marking the center.. Thus it is bad design to modify the anchorPoint for gameplay objects. Furthermore rotation or scaling will always be centered on the anchorPoint. Modifying the anchorPoint can result in undesirable behavior when rotating or scaling nodes. Let's assume..
