xcode - 我有两个物体，当碰撞时我想互相反弹，我怎样才能做到这一点，这样它就不会感觉到碰撞？

Question

我有一个屋顶 Sprite 节点，我希望玩家 Sprite 节点能够从该节点反弹，但是当它们触摸它时，就会运行我的碰撞函数。屋顶和玩家物理类别:

struct PhysicsCatagory {
static let Player : UInt32 = 0x1 << 1
static let Roof : UInt32 = 0x1 << 6

}

玩家和屋顶代码:

   Player = SKSpriteNode(imageNamed: "plane")
    Player.size = CGSize(width: 60, height: 70)
    Player.physicsBody = SKPhysicsBody(rectangleOfSize: Player.size)
    Player.position = CGPoint(x: self.frame.width / 2 - Player.frame.width, y: self.frame.width / 2)
    Player.physicsBody?.categoryBitMask = PhysicsCatagory.Player
    Player.physicsBody?.collisionBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Mine | PhysicsCatagory.Ep | PhysicsCatagory.Bullet
    Player.physicsBody?.contactTestBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Mine | PhysicsCatagory.Ep | PhysicsCatagory.Bullet
    Player.physicsBody?.affectedByGravity = false
    Player.physicsBody?.dynamic = false
    Player.zPosition = 4

   Roof.size = CGSize(width: self.frame.width, height: 40)
    Roof.physicsBody = SKPhysicsBody(rectangleOfSize: Roof.size)
    Roof.position = CGPoint(x:  self.frame.width / 2, y:  self.frame.height - 20)
    Roof.physicsBody?.categoryBitMask = PhysicsCatagory.Roof
    Roof.physicsBody?.affectedByGravity = false
    Roof.physicsBody?.dynamic = false
    Roof.zPosition = 4

这是我在发生碰撞时的代码:

    func didBeginContact(contact: SKPhysicsContact) {

    game = false
    end = true
    soundy = false
    self.removeAllChildren()
    self.removeAllActions()
    endScreen()

}

我尝试将他们的身份更改为 0，但随后玩家就冲破了屋顶。如果您对此有所了解，请在下面留下任何建议或建议。谢谢您

如果您不希望发生 didBeginContact，请删除 contactTestBitmask
