Ios 当这行代码运行时，游戏结束

我试图通过添加以下代码行，在didMove函数中完成我的游戏：

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

我希望这样，如果玩家的速度降到10以下，那么游戏应该结束并移动到下一个viewController

此外，即使运行了gameOver功能，游戏场景仍会继续检测碰撞并报告碰撞，如何停止碰撞

这是带位掩码的DIDBGIN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


    }

}

方法中是否有一些代码？已修复。问题出在钻头面罩上。

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


    }
