SpriteKit PhysicsBody non-rectangular collision

Question

    pipeUp.physicsBody = SKPhysicsBody(rectangleOfSize: pipeUp.size)

in this coding I used the rectangleOfSize for collision physics body, but if I want to use by pixel just the shape of the image, what I should use instead of rectangleOfSize?

Answer 1

You should make a CGPath that is the shape of your object, and use SKPhysicsBody's init(polygonFromPath path: CGPath) as described here
