xcode - Xcode(swift) 中的碰撞检测不起作用，我正在尝试设置玩家无法跨越的边界

Question

我有 SKContactDelegate 设置

class GameScene: SKScene, SKPhysicsContactDelegate
{
    override func didMoveToView(view: SKView)
{
    self.physicsWorld.contactDelegate = self

这里我设置了枚举

enum ColliderType:UInt32
{
    case Player = 1
    case Boundary = 2
}

这里我制作了玩家节点。

let playerTexture = SKTexture(imageNamed: "testCircle1.png")
    thePlayer = SKSpriteNode(texture: playerTexture)
    thePlayer.position = CGPointMake(frame.size.width - 350, frame.size.height/2)
    thePlayer.zPosition = 5
    thePlayer.size = CGSize(width: 100, height: 100)
    thePlayer.name = "playerNode"
    thePlayer.physicsBody = SKPhysicsBody(circleOfRadius: playerTexture.size().height/2)
    thePlayer.physicsBody!.dynamic = false
    thePlayer.physicsBody!.allowsRotation = false

    thePlayer.physicsBody!.categoryBitMask = ColliderType.Player.rawValue
    thePlayer.physicsBody!.contactTestBitMask = ColliderType.Boundary.rawValue
    thePlayer.physicsBody!.collisionBitMask = ColliderType.Boundary.rawValue
    addChild(thePlayer)

然后我设置边界

ground = SKSpriteNode(color: UIColor.redColor(), size: CGSizeMake(frame.size.width - 150, 10))
    ground.position = CGPointMake(frame.size.width/2 - 75, 96)
    ground.zPosition = 5
    ground.physicsBody = SKPhysicsBody(rectangleOfSize:     CGSizeMake(ground.size.width, ground.size.height))
    ground.physicsBody!.dynamic = false
    ground.physicsBody!.allowsRotation = false

    ground.physicsBody!.categoryBitMask = ColliderType.Boundary.rawValue
    ground.physicsBody!.contactTestBitMask = ColliderType.Player.rawValue
    ground.physicsBody!.collisionBitMask = ColliderType.Player.rawValue
    addChild(ground)

    sky = SKSpriteNode(color: UIColor.redColor(), size: CGSizeMake(frame.size.width - 150, 10))
    sky.position = CGPointMake(frame.size.width/2 - 75, frame.size.height - 96)
    sky.zPosition = 5
    sky.physicsBody = SKPhysicsBody(rectangleOfSize: CGSizeMake(frame.size.width - 150, 10))
    sky.physicsBody!.dynamic = false
    sky.physicsBody!.allowsRotation = false

    sky.physicsBody!.categoryBitMask = ColliderType.Boundary.rawValue
    sky.physicsBody!.contactTestBitMask = ColliderType.Player.rawValue
    sky.physicsBody!.collisionBitMask = ColliderType.Player.rawValue
    addChild(sky)

然后是碰撞检测

func didBeginContact(contact: SKPhysicsContact)
{
    print("Contact")
    if contact.bodyA.categoryBitMask == ColliderType.Boundary.rawValue || contact.bodyB.categoryBitMask == ColliderType.Boundary.rawValue
    {
        print("Contact")
        thePlayer.removeAllActions()
    }
}

我尝试将 print 放在 if 语句之外，以查看它是否检测到碰撞，但事实并非如此。

我看过很多教程并遵循他们所做的，但它就是行不通，而且我只有几周的时间来提交它。

Answer 1

在玩家节点

删除这个:

thePlayer.physicsBody!.dynamic = false

这就是将物理体设置为边界而不是物体......
