Hello,

I'm working on Project one from the Dive Into Sprite Kit book. I'm doing the racer version and just added the player (motorbike). Everything works fine on the simulator but when I try it on my iPad (Air 2, same version as simulator) the player doesn't show up. The background and the particles work fine but I can't see the player. I have retraced my steps to make sure I'm writing the code as the book says. I have googled the problem but still can't find an answer. Anyone have any suggestions?

This is the code I have now:

import SpriteKit
import CoreMotion

@objcMembers
class GameScene: SKScene {
  let player = SKSpriteNode(imageNamed: "player-motorbike.png")

  let motionManager = CMMotionManager()
  var gameTimer: Timer?

  override func didMove(to view: SKView) {
    // this method is called when your game scene is ready to run
    let background = SKSpriteNode(imageNamed: "road.jpg")
    background.zPosition = -1
    addChild(background)

    if let particles = SKEmitterNode(fileNamed: "Mud") {
        // Creates 10 s worth of particles as soon as the game starts
        particles.advanceSimulationTime(10)
        // start emiting at edge of iPad
        particles.position.x = 512
        // add to scene
        addChild(particles)

        player.position.x = -400
        player.zPosition = 1
        addChild(player)

        motionManager.startAccelerometerUpdates()

    }
  }

  override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
      // this method is called when the user touches the screen
  }

  override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
      // this method is called when the user stops touching the screen
  }

  override func update(_ currentTime: TimeInterval) {
    // this method is called before each frame is rendered
    if let accelerometerData = motionManager.accelerometerData {
        let changeX = CGFloat(accelerometerData.acceleration.y) * 100
        let changeY = CGFloat(accelerometerData.acceleration.x) * 100
        player.position.x -= changeX
        player.position.y += changeY
    }
  }
}

Thank you
