Change position of a SKSpriteNode that has a physicsBody

Question

I can\'t change the position of a SKSpriteNode by changing

self.position = newPosition;

It doesn\'t work anymore if it has a physicsBody.

Answer 1

I ran into a similar problem. When using SKAction, even with duration set to 0.0 I got strange behaviours especially when two SKActions had been triggered at the same time.

I tried setting position directly but as mentioned by others this doesn't work when using the SKPhysicsContactDelegate.

However for me it worked to remove the node from its parent, I then set the new position, and other things I want to change, and then I add the node again to its former parent.

It's not ideal but in some cases it might help.

As an example with the SKPhysicsContactDelegate method didBegin:

func didBegin(_ contact: SKPhysicsContact) {

    guard let node = contact.bodyB.node else { return }

    node.removeFromParent()
    node.position = CGPoint(x: 10, y: 10)
    addChild(node)
}
