我在处理以下错误时遇到问题：
c2660：c：\ users \ lukas plaehn \ desktop \ oop \ sokoban \ sokoban \ main.cpp（126）：错误C2660：'CPlayer :: moveUp'：函数不带1个参数
c2061：c：\ users \ lukas plaehn \ desktop \ oop \ sokoban \ sokoban \ player.h（10）：错误C2061：语法错误：标识符'CMaze'
我要做的是将一个对象作为头文件中的参数传递。我也尝试过参考，但它不起作用。不知何故，编译器不允许我在头文件CMaze中声明CPlayer类型的任何内容。

我猜这与你不包括来自player.h的迷宫头的事实有关...这意味着当你传递值时（这很糟糕，因为它会导致不必要的副本）尽管想要使用它，该函数对CMaze对象一无所知。
如果您将CMaze作为指针或引用传递，我怀疑问题会消失。但是，您需要记住，通过执行此操作，您的函数内的任何后续CMaze修改都将导致传入的CMaze也发生更改。
