場景精靈套件合格分數

Question

我試圖將我的分數從GameScene傳遞到GameOverScene。 我只想在GameOverScene中使用我傳遞給它的變量Score設置標籤的文本。 我使用這個：

SKView *spriteView = (SKView *) self.view; 
    SKScene *currentScene = [spriteView scene]; 
    GameOverScene *gameOverScene = [GameOverScene sceneWithSize:self.frame.size]; 
    [gameOverScene.userData setObject:[currentScene.userData objectForKey:@"score"] forKey:@"score"]; 
    [self.view presentScene:gameOverScene transition:[SKTransition doorsCloseHorizontalWithDuration:1]]; // animation 

我現在該如何訪問得分變量在我GameOverScene？

感謝您的任何答案。

編輯：

好吧我有一個變量int分數; 。我如何將objectForKey@"score"連接到這個變量？

EDIT2：

[score setText:[NSString stringWithFormat:@"Score: %@", [self.userData valueForKey:@"score"]]]; 

有了，我得到的分數：(null)

Answer 1

首先，你需要在didMoveToView初始化userData爲GameScene：

self.userData = [NSMutableDictionary dictionary]; 

之後，如果你想要保存您的整數score，請添加：

score = 100; // assume your score is 100 now 
[self.userData setObject:[NSString stringWithFormat:@"%d", score] forKey:@"score"]; 

權呈現一個場景前，編輯您在這樣的問題發佈的代碼：

SKView *spriteView = (SKView *)self.view; 
SKScene *currentScene = [spriteView scene]; 
GameOverScene *gameOverScene = [GameOverScene sceneWithSize:self.frame.size]; 

// Initialize userData for the next scene 
gameOverScene.userData = [NSMutableDictionary dictionary]; 
[gameOverScene.userData setObject:[currentScene.userData objectForKey:@"score"] forKey:@"score"]; 
NSLog(@"GameScene score: %lu", [[currentScene.userData objectForKey:@"score"] integerValue]); 

[self.view presentScene:gameOverScene transition:[SKTransition doorsCloseHorizontalWithDuration:1]]; 

現在你應該看到您的新場景，並檢查得分需要的地方：

int score = [[self.userData objectForKey:@"score"] intValue]; 
NSLog(@"GameOverScene score: %d", score);
