Question

我试图通过添加以下代码行来使我的游戏在didMove函数中结束：

if ((player.physicsBody?.velocity.dx)! < CGFloat(10.0)) {
      gameOver()                
} else if ((player.physicsBody?.velocity.dy)! <  CGFloat(10.0)) {
      gameOver()                           
}

这是gameOver（）函数：

func gameOver() {

  score = Watch.elapsedTime

  player.physicsBody?.contactTestBitMask = 0
  player.physicsBody?.collisionBitMask = 0
  player.physicsBody?.categoryBitMask = 0

  hitSoundEffect?.stop()
  bounceSoundEffect?.stop()     
  Watch.stop()   
  motionManager.stopAccelerometerUpdates()

  if score > highScore {
        UserDefaults.standard.set(Int(score), forKey: "highScore")   
  }

  let storyboard = UIStoryboard(name: "Main", bundle: nil)             
  let vc1 = storyboard.instantiateViewController(withIdentifier: "gameoverVC")

  vc1.modalPresentationStyle = .fullScreen
  vc1.modalTransitionStyle = .crossDissolve

  self.getTopMostViewController()?.present(vc1, animated: true, completion: nil)     
}

我想要这样，如果玩家的速度降至10以下，则游戏应该结束并移至下一个viewController。

即使运行了gameOver函数，gameScene仍然继续检测碰撞并报告碰撞，如何停止碰撞？

这是带有位掩码的didBegin函数：

let PlayerHitCategory: UInt32 = 5;
let ObjectHitCategory: UInt32 = 4;
let WallHitCategory: UInt32 = 3;

    player.physicsBody?.categoryBitMask = PlayerHitCategory
    player.physicsBody?.collisionBitMask = ObjectHitCategory | WallHitCategory
    player.physicsBody?.contactTestBitMask = ObjectHitCategory

   object.physicsBody?.contactTestBitMask = ObjectHitCategory | PlayerHitCategory
   object.physicsBody?.categoryBitMask =  ObjectHitCategory
   object.physicsBody?.collisionBitMask = ObjectHitCategory | PlayerHitCategory

    physicsBody.categoryBitMask = WallHitCategory
    physicsBody.collisionBitMask = 0
    physicsBody.contactTestBitMask = PlayerHitCategory

func didBegin(_ contact: SKPhysicsContact) {

    //   print("didBeginContact entered for \(String(describing: contact.bodyA.node!.name)) and \(String(describing: contact.bodyB.node!.name))")

let contactMask = contact.bodyA.categoryBitMask | contact.bodyB.categoryBitMask

switch contactMask {

    case PlayerHitCategory | ObjectHitCategory:

    hitSound()
    playerDisplacement()
    print("Collided with object")

    case PlayerHitCategory | WallHitCategory:

    bounceSound()

    print("Collided with wall")

default: break


    }

}

运行此行代码，游戏就结束了
