Is it possible to rotate a Node around an arbitrary point in SpriteKit?

Question

Is there a way to rotate a Node in SpriteKit around an arbitrary point? I now I can manipulate the anchorPoint of my Node, but that is not sufficient if the rotation point I want to use lies outside of the Node.

What is the best way to achieve this kind of rotation in SpriteKit?

Answer 1

Since you're asking for the best way, here's one that works well (best is subjective):

Create an SKNode and set its position to the center of rotation. Add the node that should rotate around that center as child to the center node. Set the child node's position to the desired offset (ie radius, say x + 100). Change the rotation property of the center node to make the child node(s) rotate around the center point. The same works for cocos2d btw.
