Question

我试图创建一个游戏，其中玩家旋转spritenode以使用正确的颜色击中右侧spritenode。我放置一个固定在主屏幕上的spritenode（node1），并在每个方向上固定4个spritenode。（redPoint，bluePoint，greenPoint和brownPoint）。当玩家触摸node1精灵时，它应该旋转90度。颜色精灵应该保持锁定在node1上并向正确的方向移动。

几乎所有东西都应该工作，颜色精灵被固定在node1上的位置。然而，整个小组并没有像它应该的那样旋转90度。它旋转但不是90度。

如果我注释掉除node1之外的所有内容并测试触摸精灵它确实旋转了90度。

有人知道我可以做些什么来解决这个问题吗？或者我做错了什么或有人有不同的方法？

我附上了我使用过的代码：

class GameScene: SKScene, SKPhysicsContactDelegate {  

    var node1 = SKSpriteNode()
    var redPoint = SKSpriteNode()
    var bluePoint = SKSpriteNode()
    var greenPoint = SKSpriteNode()
    var brownPoint = SKSpriteNode()

    override func didMove(to view: SKView) {
        physicsWorld.contactDelegate = self
        playerTri()
    }

    func playerTri(){

        node1 = SKSpriteNode(color: .black, size: CGSize(width: self.size.width * 0.2, height: self.size.width * 0.2))

        redPoint = SKSpriteNode(color: .red, size: CGSize(width: node1.size.width * 0.5, height: node.size.width * 0.5))
        bluePoint = SKSpriteNode(color: .blue, size: CGSize(width: node1.size.width * 0.5, height: node1.size.width * 0.5))
        greenPoint = SKSpriteNode(color: .green, size: CGSize(width: node1.size.width * 0.5, height: node1.size.width * 0.5))
        brownPoint = SKSpriteNode(color: .brown, size: CGSize(width: node1.size.width * 0.5, height: node1.size.width * 0.5))

        node1.position = CGPoint(x: self.frame.midX, y: self.frame.minY + node1.size.height)
        node1.zPosition = 2
        node1.physicsBody = SKPhysicsBody(rectangleOf: node1.size)
        node1.physicsBody?.affectedByGravity = false
        node1.physicsBody?.pinned = true
        node1.zRotation = 0.0

        redPoint.position = CGPoint(x: node1.frame.minX, y: node1.frame.midY)
        redPoint.zPosition = 3
        redPoint.anchorPoint = node1.anchorPoint
        redPoint.physicsBody = SKPhysicsBody(rectangleOf: redPoint.size)
        redPoint.physicsBody?.affectedByGravity = false

        bluePoint.position = CGPoint(x: node1.frame.maxX, y: node1.frame.midY)
        bluePoint.zPosition = 3
        bluePoint.physicsBody = SKPhysicsBody(rectangleOf: bluePoint.size)
        bluePoint.physicsBody?.affectedByGravity = false

        greenPoint.position = CGPoint(x: node1.frame.midX, y: node1.frame.maxY)
        greenPoint.zPosition = 3
        greenPoint.physicsBody = SKPhysicsBody(rectangleOf: greenPoint.size)
        greenPoint.physicsBody?.affectedByGravity = false

        brownPoint.position = CGPoint(x: node1.frame.midX, y: node1.frame.minY)
        brownPoint.zPosition = 3
        brownPoint.physicsBody = SKPhysicsBody(rectangleOf: greenPoint.size)
        brownPoint.physicsBody?.affectedByGravity = false

        let joint = SKPhysicsJointFixed.joint(withBodyA: node1.physicsBody!, bodyB: redPoint.physicsBody!, anchor: CGPoint(x: node1.frame.minX, y: node1.frame.midY))

        let joint2 = SKPhysicsJointFixed.joint(withBodyA: node1.physicsBody!, bodyB: bluePoint.physicsBody!, anchor: CGPoint(x: node1.frame.maxX, y: node1.frame.midY))

        let joint3 = SKPhysicsJointFixed.joint(withBodyA: node1.physicsBody!, bodyB: greenPoint.physicsBody!, anchor: CGPoint(x: node1.frame.midX, y: node1.frame.maxY))

        let joint4 = SKPhysicsJointFixed.joint(withBodyA: node1.physicsBody!, bodyB: brownPoint.physicsBody!, anchor: CGPoint(x: node1.frame.midX, y: node1.frame.minY))

        addChild(node1)
        addChild(redPoint)
        addChild(bluePoint)
        addChild(greenPoint)
        addChild(brownPoint)

        scene?.physicsWorld.add(joint)
        scene?.physicsWorld.add(joint2)
        scene?.physicsWorld.add(joint3)
        scene?.physicsWorld.add(joint4)
    } 

    func rotate(){
        let rotate1 = SKAction.rotate(byAngle: .pi / 2, duration: 0.1)

        node1.run(rotate1)
    }

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

        guard let touch = touches.first else {return}
        let location = touch.location(in: self)
        let tappedNodes = nodes(at: location)

        if tappedNodes.contains(node1){
            rotate()
        }   
    }
}
