我正在尝试制作一个游戏，其中每个玩家都有结构，并将这些玩家结构存储在一个数组中。现在我尝试向游戏添加保存/加载功能，保存玩家数量和每个玩家的结构，但由于某种原因我无法弄清楚如何正确存储数据。我正在使用一个二进制文件，并尝试将整个数组读取到变量中，以便游戏可以继续，但它要么根本不加载文件，要么游戏将玩家计数读取为 0 然后结束。有什么建议么？谢谢您的帮助。抱歉代码很长。

我尝试单独存储每个结构并单独读取每个结构，并调试在加载时打印玩家计数，但每次玩家计数读取为 0，所以我想知道它是否未正确保存，或者是否保存在整数上与结构。
您可以在程序开始时打开文件，如下所示：
FILE* file = fopen("file.bin", "wb");
请注意，“w”作为模式参数将破坏文件内容（如果文件已存在），因此您无法加载任何内容。
