Physicsbody doesn't adhere to node's anchor point

Question

My scene has a bunch of rectangles with physics bodies that are the same size as the rectangle. I like to anchor all of my objects to CGPointZero, however I\'ve noticed when

Answer 1

Swift 4.1

let centerPoint = CGPoint(x: house1.size.width / 2 - (house1.size.width * house1.anchorPoint.x), y: house1.size.height / 2 - (house1.size.height * house1.anchorPoint.y))

house1.physicsBody = SKPhysicsBody(rectangleOf: house1.size, center: centerPoint)
