swift - 移动到另一个 .SKS 文件的正确方法

Question

我有一个游戏，其中有两个场景:FarmScene 和 WoodScene。每个场景都有一个 .SKS 文件和一个 .swift 文件 - 一个用于设计，一个用于编码。我已经成功地从 FarmScene 转移到 WoodScene，就像这样:

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in touches {
        let location = touch.location(in: self)
        let node : SKNode = self.atPoint(location)
        if node.name == "WoodIcon" {
            if let view = self.view as! SKView? {
                // Load the SKScene from 'GameScene.sks'
                if let scene = SKScene(fileNamed: "WoodScene") {
                    // Set the scale mode to scale to fit the window
                    scene.scaleMode = .aspectFill

                    // Present the scene
                    view.presentScene(scene)
                }
            }
        }
    }
}

在我以前的游戏中，我使用了 SKTransition 来移动到不同的场景，并且我可以用它来做一些很酷的过渡，比如翻转、淡入淡出和插入。

我想知道这是否是在 Xcode 中使用场景设计器时更改场景的“正确”方式？或者我可能遗漏了什么。

期待您的来信。

我不会用循环那样做，只是为了防止您可能多次运行该演示代码。也许用 guard 语句设置你的 touchesBegan 方法

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    // Guard to just use the first touch
    guard let touch = touches.first else { return }
    let location = touch.location(in: self)
    let node : SKNode = self.atPoint(location)
    if node.name == "WoodIcon" {
        if let view = self.view as! SKView? {
            // Load the SKScene from 'GameScene.sks'
            if let scene = SKScene(fileNamed: "WoodScene") {
                // Set the scale mode to scale to fit the window
                scene.scaleMode = .aspectFill

                // Present the scene
                view.presentScene(scene)
            }
        }
    }
}

此外，如果您想通过代码进行自定义转换，您可以这样做:

func customTransition() {

    // Wait three seconds then present a custom scene transition
    let wait = SKAction.wait(forDuration: 3.0)
    let block = SKAction.run {

        // Obviously use whatever scene you want, this is just a regular GameScene file with a size initializer
        let newScene = SKScene(fileNamed: "fileName")!
        newScene.scaleMode = .aspectFill
        let transitionAction = SKTransition.flipHorizontal(withDuration: 0.5)
        self.view?.presentScene(newScene, transition: transitionAction)

    }
    self.run(SKAction.sequence([wait, block]))

}

我不会说有对或错的方式，只是关于您希望过渡看起来有多花哨的偏好。
