C++ Ctry 将整数和 struct 数组存储到二进制文件中

我正在try 制作一个游戏，其中每个玩家都有 struct ，并将这些玩家 struct 存储在一个数组中.现在，我试图在游戏中添加一个保存/加载功能，保存玩家的数量和每个玩家的 struct ，但由于某些原因，我不知道如何正确地存储数据.我正在使用一个二进制文件，并try 将整个数组读入变量，这样游戏就可以继续，但它要么根本不加载文件，要么游戏将playercount读取为0并直接结束.有什么建议吗？谢谢你的帮助.抱歉，代码太长了.

我try 逐个存储和读取每个 struct ，并在加载时调试打印playercount，但每次playercount读取为0，所以我想知道它是否没有正确保存，或者是否通过 struct 保存了整数.
