在ViewController中检测对SKNode的触摸

class ViewController: UIViewController, SKSceneDelegate {
    var skView: SKView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        skView = SKView(frame: view.bounds)
        skView.delegate = self
        view.addSubview(skView)
    }
}

class GameScene: SKScene {
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        // 在这里处理触摸事件的逻辑
        for touch in touches {
            let location = touch.location(in: self)
            let touchedNode = self.atPoint(location)
            
            if touchedNode is SKNode {
                // 对SKNode的触摸逻辑处理
            }
        }
    }
}

class ViewController: UIViewController, SKSceneDelegate {
    var skView: SKView!
    var gameScene: GameScene!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        skView = SKView(frame: view.bounds)
        skView.delegate = self
        
        gameScene = GameScene(size: skView.bounds.size)
        skView.presentScene(gameScene)
        
        view.addSubview(skView)
    }
}
