Question

我是编码的初学者。我的一个朋友过去常常帮助我，但现在他很忙，所以我必须独自做事。游戏具有记住玩家在玩游戏之前输入的名称以及玩家得分的功能。现在，我的问题是，当我玩游戏时，它并没有出现在我的排行榜场景中。然后当我用另一个名字玩另一轮时，我可以看到之前的分数，但不是我现在的分数。就像数据延迟出现一样。

void ReplaceRank(string player, int currentScore) {
    string oldName;
    int oldScoreNumber;

    for (int i = 0; i < 10; i++) {
        if (currentScore > scores[i]) {
            highscoreShow.enabled = true;
            oldScoreNumber = scores[i];
            oldName = PlayerPrefs.GetString(oldPlayerName[i]);
            PlayerPrefs.SetInt(oldScore[i], currentScore);
            PlayerPrefs.SetString(oldPlayerName[i], player);
            Debug.Log(currentScore);
            if (i <= 9) {
                ReplaceRank(oldName, oldScoreNumber);
            }
            break;
        }
    }
}

private void GetAllKeys() {
    oldScore = new List<string>();
    oldPlayerName = new List<string>();
    scores = new List<int>();

    for (int i = 11; i < 21; i++) {
        if (PlayerPrefs.GetString("score" + i + "Name", "") == "") {
            PlayerPrefs.SetString("score" + i + "Name", "");
        }
        oldPlayerName.Add("score" + i + "Name");
        oldScore.Add("score" + i);
        scores.Add(PlayerPrefs.GetInt("score" + i, 0));
    }
}

即使这看起来微不足道，但保存有点棘手，你可以做的一些事情可以让它变得更容易，例如你应该将分数保存为列表

保存

1. 将分数添加到列表
2. 将分数列表转换为Json
3. 在播放器首选项中保存json字符串

装载

1. 从播放器首选项中获取json字符串
2. 将Json转换为列表
3. 脚本中的更新列表

快速编写了这个类..它的测试和工作但你可能需要修改它以满足你的需求并改进它
