I want to fix an SKNode (the node has a physics body) in space by pinning it to the SKScene. So it can participate in the physics simulation - collide, spin, etc. But not move. Is this allowable? Is there a better way to fix an physical node in space yet have it participate in the physics simulation?

Ah hah! lightbulb has gone off in my head. Pose this as an answer and I will give it to you. Cheers. – dugla Oct 22 '14 at 19:12

Yes, you can, by setting dynamic property to NO:
node.physicsBody.dynamic = NO;

Nicael, but SKScene is inherently edge-based (ie, dynamic = no) so there should be no need to set it explicitly. No? – dugla Oct 22 '14 at 19:22

@dugla I mean that you should set this for SKNode... or am I misunderstanding the question? – nicael Oct 22 '14 at 19:23

I want an SKNode - SKSpriteNode typically - to be pinned in space using the SKScene as the pin board. So the SKScene is a pin board, each sprite has a pin, I pin the sprite to the pinboard. – dugla Oct 22 '14 at 19:28

@dulga So whats wrong with my answer?? Set the `physicsBody.dynamic` of this SKNode to `NO`. – nicael Oct 22 '14 at 19:31
