I wrote this to fix Apple’s lack thereof: use pathForRectangleOfSize:withAnchorPoint: to replace your call to bodyWithRectangleOfSize: whose brief documentation tells us the problem: “Creates a rectangular physics body centered on the owning node’s origin.” @implementation SKPhysicsBody (CWAdditions) + (CGPathRef)pathForRectangleOfSize:(CGSize)size withAnchorPoint:(CGPoint)anchor { CGPathRef path = CGPathCreateWithRect( CGRectMake(-size.width * anchor.x, -size.height * anchor.y, size.width, size.height), nil); return … Read more
