Centering the camera on a node in swift spritekit

Question

I am creating a Terraria-style game in Swift. I want to have it so the player node is always in the center of the screen, and when you move right the blocks go left like in Terr

Answer 1

You have to create World node that contains nodes. And you should put anchorPoint for example (0.5,0.5). Center on your player. And then you should move your player.

func centerOnNode(node:SKNode){

   let cameraPositionInScene:CGPoint = self.convertPoint(node.position, fromNode: world!)
   world!.position = CGPoint(x:world!.position.x - cameraPositionInScene.x, y: world!.position.y - cameraPositionInScene.y)
}


override func didSimulatePhysics() {
  self.centerOnNode(player!)
}
