2 Fixed typo edited Mar 9 '16 at 16:20 Heyfara 11144 bronze badges Have you tried to initialize your SKPhysicsBody with a rectangle of the size you want? var node = SKSpriteNode(imageNamed: "node.png") node.physicsBody = SKPhysicsBody(rectangleOfSize: CGSize(width: 50, height: 50))  That way you can increase the size of the bounding box of youyour node without using a larger image. More details in the docs. Hope it helps!
