swift – 为SKScene创建一个自定义的initalizer,它会覆盖方便的i

我正在尝试创建一个方便初始化程序来覆盖方便初始化？ SKScene中的(fileNamed :)初始化程序,以便我可以将一些初始值传递给场景,同时取消归档.sks文件.问题是,当我尝试这样做时,似乎SKScene(GameScene)的子类无法看到方便的init？超类的(fileNamed :).以下是我的一些尝试：

Class GameScene : SKScene {

var stage : Int?

override init(size: CGSize) {
    super.init(size: size)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

convenience init?(fileNamed: String,stage: Int) {
    self.init(fileNamed: fileNamed)  // Compiler error-- Argument labels '(filenamed:)' do not match any available overloads
    self.stage = stage
}

我发现的另一个尝试建议作为解决方法：

Class GameScene : SKScene {

var stage : Int?

override init(size: CGSize) {
    super.init(size: size)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

convenience init?(fileNamed: String) {
    self.init(fileNamed: fileNamed) // Error at run time: EXC_BAD_ACCESS (code=2,address=0x16fc1bff0) 
}

convenience init?(fileNamed: String,stage: Int) {
    self.init(fileNamed: fileNamed)  
    self.stage = stage
}

调试器显示无限循环的GameScene.init(fileNamed：String) – > GameScene？

我该如何做到这一点？我需要继续我的生活！ (和这个项目……)

if let gameScene = GameScene(fileNamed: "GameScene") {

        self.gameScene = gameScene
        self.gameScene.stage = 1
        self.gameScene.setupBasedOnStage()
        self.gameScene.scaleMode = .aspectFill
        self.gameScene.gameSceneDelegate = self.menuSceneDelegate as! GameSceneDelegate!
        self.view?.presentScene(self.gameScene,transition: SKTransition.reveal(with: .down,duration: 1.0))
    }
