我对
Swift很陌生,而且我在游戏中实现排行榜时遇到了一些麻烦.我刚看了一个教程：’游戏中心排行榜！ (Xcode中的Swift 2)’其中GameCenter信息都通过应用程序的一个视图.在我的游戏中,我希望用户能够玩游戏,然后只有当他们使用特定的SKScene时,他们才能访问GameCenter.
因此,例如,在GameOverScene上,他们将进行用户身份验证,并且还可以上传他们的高分.我想我也错过了GameViewController(所有教程逻辑所在的位置)和我制作的众多场景之间的一些差异.
这是我的代码,我尝试在GameOverScene上使用GKGameCenterControllerDelegate并创建各种功能以到达GameCenter.当用户在视图中点击某个标签时进行调用:(这显然不起作用,因为我正在尝试访问这样的行上的场景：self.presentViewController(view！,animated：true,completion：nil)
class GameOverScene: SKScene,GKGameCenterControllerDelegate {
init(size: CGSize,the@R_301_182@:Int) {
@R_301_182@ = the@R_301_182@
super.init(size: size)
}
...
override func didMoveToView(view: SKView) {
authPlayer()
leaderboardLabel.text = "Tap for Leaderboard"
leaderboardLabel.fontSize = 12
leaderboardLabel.fontColor = SKColor.redColor()
leaderboardLabel.position = CGPoint(x: size.width*0.85,y: size.height*0.1)
addChild(leaderboardLabel)
...
override func touchesBegan(touches: Set<UITouch>,withEvent event: UIEvent?) {
for touch : AnyObject in touches {
let location = touch.locationInNode(self)
if(CGRectContainsPoint(leaderBoardLabel.frame,location)){
saveHigh@R_301_182@(@R_301_182@)
showLeaderBoard()
}
}
}
func authPlayer(){
//Create a play
let localPlayer = GKLocalPlayer.localPlayer()
//See if signed in or not
localPlayer.authenticateHandler = {
//A view controller and an error handler
(view,error) in
//If there is a view to work with
if view != nil {
self.presentViewController(view!,animated:true,completion: nil) //we dont want a completion handler
}
else{
print(GKLocalPlayer.localPlayer().authenticated)
}
}
}
//Call this when ur high@R_301_182@ should be saved
func saveHigh@R_301_182@(number:Int){
if(GKLocalPlayer.localPlayer().authenticated){
let @R_301_182@Reporter = GK@R_301_182@(leaderboardIdentifier: "@R_301_182@Board")
@R_301_182@Reporter.value = Int64(number)
let @R_301_182@Array: [GK@R_301_182@] = [@R_301_182@Reporter]
GK@R_301_182@.report@R_301_182@s(@R_301_182@Array,withCompletionHandler: nil)
}
}
func showLeaderBoard(){
let viewController = self.view.window?.rootViewController
let gcvc = GKGameCenterViewController()
gcvc.gameCenterDelegate = self
viewController?.presentViewController(gcvc,animated: true,completion: nil)
}
func gameCenterViewControllerDidFinish(gameCenterViewController: GKGameCenterViewController) {
gameCenterViewController.dismissViewControllerAnimated(true,completion: nil)
}
关于如何进行此操作的任何建议都会很棒,我认为我可能会让整个场景/视图控制器混乱并导致问题.谢谢！
这个答案部分地延续了我们在评论中所停留的位置,因为你没有发布你的整个代码,我无法确切地知道你的挂断在哪里,但这是我和一个单独的指南放在一起的(这是一个稍微的您发布的不同版本的代码)：
大部分代码的作者：

localPlayer.authenticateHandler = {(viewController,error) -> Void in
if (viewController != nil) {
self.presentViewController(viewController!,completion: nil)
}
else {
print((GKLocalPlayer.localPlayer().authenticated))

要特别注意
29:
let my_leaderboard_id = "YOUR_LEADERBOARD_ID"
我在那里放了一些愚蠢的ASCII艺术,以确保你不会错过它.您必须从GameCenter设置中输入您的实际排行榜ID.
您还必须添加GameCenter库,然后执行iTunes连接以在弹出窗口中实际查看您的高分.
我认为你最初的问题是没有理解SpriteKit甚至iOS视图如何工作的后端(这完全没问题,因为Apple让人很容易进入并且很容易).但是,如您所见,遵循指南/教程可能很困难,因为您的实施会有所不同.
以下是一些很好的信息：
SK中每个帧发生的情况图：
所以你看,SKScene是一个包含节点和动作等所有有趣内容的类,并且是一切(对你很重要)发生的地方.您可以通过编辑器生成这些场景,但是您可能需要创建一个新的.swift文件(因为每个场景都有自己的逻辑).
编辑器只是初始化一堆东西的“捷径”,老实说,你可以用很少的代码制作完整的游戏(但你很快发现你想要更多)
所以在这段代码中,你声明了GameScene或PauseScreen(它们基本上只是类声明,继承自SKScene),你很快就会发现这一行谈论ISNT场景：
override func didMoveToView(view: SKView)
.. it’s calling a SKView… what is that,and where did it come from?(Read about SKView here,and look at its inheritance):
07002
我们在GameViewController文件中找到这个SKView声明(这只是一个类),注意它与普通的iOS应用程序大致相同,因为它继承了UIViewController：
override func viewDidLoad() {
super.viewDidLoad()
if let scene = GameScene(fileNamed:"GameScene") {
// Configure the view.
let skView = self.view as! SKView
skView.showsFPS = true
skView.showsNodeCount = true
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = true
/* Set the scale mode to scale to fit the window */
scene.scaleMode = .AspectFill
skView.presentScene(scene)
}
同样,该方法在GameViewController.swift中声明,基本上就是这样：
class GameViewController：UIViewController
那么所有这些与iOS应用和SpriteKit有什么关系呢？好吧,他们都被捣碎在彼此之上：
IOS app解剖：
基本上,从右到左,你有一个Window,它是(如果错误的话,我是错误的)AppDelegate,然后是ViewController,然后是你的View,里面有所有很酷的东西(Storyboards就在View里面,就像SKScenes位于View ….标签,节点或按钮内,都位于各自的类中((视图)))
这都是继承的三明治.
查看Apple网站了解更多信息.
https://developer.apple.com/spritekit/
https://developer.apple.com/library/ios/documentation/SpriteKit/Reference/SpriteKitFramework_Ref/
基本上,一切都是继承自类继承的类的类,依此类推……它可能会变得混乱.你也可以通过CMD点击它们在Xcode中看到这些遗产,这会将你跳转到源文件.
Goodluck与你在SpriteKit的学习和冒险:)
