如何从视图控制器移动到 skscene [英] How to move from view controller to skscene

问题描述

我想以 swift 语言从 UIViewController 呈现 SKScene，我正在 iOS 中开发游戏，菜单是 UIViewController，游戏在 SpriteKit 中，我需要从菜单 (UIViewController) 移动到游戏 (SKScene) 按下按钮.我怎么能做这样的事情?

I want to present SKScene from a UIViewController in swift language, I'm developing a game in iOS , the menu is a UIViewController and the game is in SpriteKit, I need to move from the menu (UIViewController) to the game (SKScene) upon pressing a button. How can I do something like that ?

推荐答案

就像@Ron Myschuk 所说的那样，您应该考虑将菜单移至 SpriteKit.如果您想使用 UIKit，您需要将 SKScene 与 UIViewController 通信(我想这是您的问题).

Like @Ron Myschuk said you should consider moving your menu to SpriteKit. If you want to use UIKit you will need to communicate the SKScene with the UIViewController (I guess that is your problem).

您可以通过 delegate 实现此目的模式.

使用此模式，您的代码可能如下所示:

Using this pattern your code might look something like this:

/// Game actions that should be notified.
Protocol GameSceneDelegate: class {
    func gameDidEnd()
}

public class GameScene: SKScene {

    weak var gameDelegate: GameSceneDelegate?

    // MARK: - Menu Actions
    func userDidPressMenuButton() {
        ///Do what you want to do..
    }
}

class GameViewController: UIViewController, GameSceneDelegate{

    var scene: GameScene?

    override func viewDidLoad() {

        if (self.view as! SKView?) != nil {
            self.scene = GameScene(fileNamed: "GameScene")
        }

        self.scene?.gameDelegate = self
    }

    // MARK: - GameSceneDelegate methods

    func gameDidEnd(){
        ///Do what you want to do..
    }

    // MARK: - Actions
    @IBAction func pressMenuButtonAction(_ sender: Any) {

        self.scene?.userDidPressMenuButton()
    }
}

当您在 UIViewController 中按下按钮时，您会调用 SKScene 来执行它需要执行的操作.当场景需要告诉菜单一个相关的动作(比如游戏结束)时，它会调用它的委托，即你的 UIViewController.

When a button is pressed in your UIViewController you call the SKScene to do what ever it needs to do. And when the scene needs to tell the menu a relevant action (like game finish) it calls its delegate, that is your UIViewController.
