Android 科罗纳的高分。文件读/写

我有一个错误：

尝试连接全局“高分”（a

nil

值）

这是我在Game.lua文件中检查高分的方式：

function HighscoreUpdate()
    if(score>Highscore)then
        Highscore = score
    end
end

这就是我如何将Highscore保存在score.txt中，并在所有冲突检查之后调用它（我在这里没有任何错误）：

这就是我尝试加载它的方式（我认为问题出在这里）：

有什么想法吗？

我看不出有什么地方你真的想把任何东西和高分联系起来。我也不知道你在哪里初始化它。默认情况下，未初始化的变量为零。如果您试图打印高分，例如：

 print("Highscore: " .. Highscore)

---

你会得到那个错误。如果你没有这个错误，你很可能会得到另一个错误，试图比较一个数字为零。因此，请确保在某个地方初始化Highscore，它将解决您的问题。

在MAIN.LUA中使用此代码
