Question

所以我正在研究这款“太空射击游戏”游戏，我遇到了一些错误，这些错误并没有让我的游戏正常运行/崩溃。

所以第一个问题是当我在“didBeginContact”中使用我创建的函数时，我的游戏有时会崩溃。这是“didBeginContact”中的代码

  func didBeginContact(contact: SKPhysicsContact) {

    let firstBody : SKPhysicsBody = contact.bodyA
    let secondBody : SKPhysicsBody = contact.bodyB

    if ((firstBody.categoryBitMask == PhysicsCatagory.fAsteroids) && (secondBody.categoryBitMask == PhysicsCatagory.Asteroids) || (firstBody.categoryBitMask == PhysicsCatagory.Asteroids) && (secondBody.categoryBitMask == PhysicsCatagory.fAsteroids)){

        asteroidsHitEachOther(firstBody.node as! SKSpriteNode, FuriousAsteroids: secondBody.node as! SKSpriteNode)

    }

    if ((firstBody.categoryBitMask == PhysicsCatagory.Asteroids) && (secondBody.categoryBitMask == PhysicsCatagory.Bullet) || (firstBody.categoryBitMask == PhysicsCatagory.Bullet) && (secondBody.categoryBitMask == PhysicsCatagory.Asteroids)){

        bulletHitAsteroids(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)

        }
    else if ((firstBody.categoryBitMask == PhysicsCatagory.fAsteroids) && (secondBody.categoryBitMask == PhysicsCatagory.Bullet) || (firstBody.categoryBitMask == PhysicsCatagory.Bullet) && (secondBody.categoryBitMask == PhysicsCatagory.fAsteroids)){

        bulletHitfAsteroids(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)

    }

    if ((firstBody.categoryBitMask == PhysicsCatagory.Asteroids) && (secondBody.categoryBitMask == PhysicsCatagory.Fighter) || (firstBody.categoryBitMask == PhysicsCatagory.Fighter) && (secondBody.categoryBitMask == PhysicsCatagory.Asteroids)){

        fighterGetHit(firstBody.node as! SKSpriteNode, Asteroids: secondBody.node as! SKSpriteNode)

    }


    else if ((firstBody.categoryBitMask == PhysicsCatagory.fAsteroids) && (secondBody.categoryBitMask == PhysicsCatagory.Fighter) || (firstBody.categoryBitMask == PhysicsCatagory.Fighter) && (secondBody.categoryBitMask == PhysicsCatagory.fAsteroids)){

        fighterGetHitHard(firstBody.node as! SKSpriteNode, fAsteroids: secondBody.node as! SKSpriteNode)

    }

  }

因此游戏有时会因这些错误而崩溃。 Error #1 Error #2

游戏崩溃的线是这些线。

asteroidsHitEachOther(firstBody.node as! SKSpriteNode, FuriousAsteroids: secondBody.node as! SKSpriteNode)

bulletHitAsteroids(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)

bulletHitfAsteroids(firstBody.node as! SKSpriteNode, Bullet: secondBody.node as! SKSpriteNode)

fighterGetHit(firstBody.node as! SKSpriteNode, Asteroids: secondBody.node as! SKSpriteNode)

fighterGetHitHard(firstBody.node as! SKSpriteNode, fAsteroids: secondBody.node as! SKSpriteNode)

现在，如果你想看看我创建函数的方式，那么你可以在这里查看所有函数。

func asteroidsHitEachOther(Asteroids: SKSpriteNode, FuriousAsteroids: SKSpriteNode){

    Asteroids.removeFromParent()
    FuriousAsteroids.removeFromParent()

}

func bulletHitAsteroids(Asteroids: SKSpriteNode, Bullet: SKSpriteNode){

    Asteroids.removeFromParent()
    Bullet.removeFromParent()

    Points++
    pointLabel.text = "Points: \(Points)"

}

func bulletHitfAsteroids(fAsteroids: SKSpriteNode, Bullet: SKSpriteNode){

    fAsteroids.removeFromParent()
    Bullet.removeFromParent()

    Points = Points + 2
    pointLabel.text = "Points: \(Points)"

}

func fighterGetHit(Fighter: SKSpriteNode, Asteroids: SKSpriteNode){

    Asteroids.removeFromParent()


    HitPoints--
    hpLabel.text = "\(HitPoints) HP"

}

func fighterGetHitHard(Fighter: SKSpriteNode, fAsteroids: SKSpriteNode){

    fAsteroids.removeFromParent()

    HitPoints = HitPoints - 2
    hpLabel.text = "\(HitPoints) HP"

}

现在，在我们谈到第一个错误之后，我将讨论第二个错误，它无法正常运行游戏。

现在我们可以看到，在上面的函数中，在“bulletHitfAsteroids”中，points变量被假设为两个。但是当我玩这个游戏时，当我击中fAsteroids时，积分只上升了一个。对于“fighterGetHitHard”来说，情况也是如此，健康状况不会下降两个，而是只下降一个。

我很感激能得到的帮助，谢谢。
