Question

我试图将我的分数从GameScene传递给GameOverScene。我只想在GameOverScene中设置标签的文本，并使用我传递给它的变量Score。我正在使用这个：

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

如何在我的GameOverScene中访问得分变量？

感谢您的回答。

编辑：

好吧我有一个变量int Score; 。如何将objectForKey@"score"连接到此变量？

EDIT2：

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

我得到分数：(null)

首先，您需要在userData中为 GameScene 初始化didMoveToView：

self.userData = [NSMutableDictionary dictionary];

之后，如果要保存整数score，请添加：

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

在呈现下一个场景之前，编辑您在问题中发布的代码，如下所示：

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]];

现在你应该看到你的新场景，并在需要的地方检查分数：

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