我觉得我正在试图找出编译器错误发生的原因。我将提供我得到的（长）编译器错误列表，并希望有人可能会建议如何纠正这些错误。我包括4个文件，其中一个很长，但为了完整起见，我将提供整个文件。
对任何一点点错误的任何帮助都会非常感激。

答案 0 :(得分：2)
您收到的所有错误都与之相关：
'...' has not been declared '...' does not name a type '...' was not declared in this scope 它们意味着编译器无法找到这些对象的声明，因为它们位于单独的文件中，并且您不需要将它们包含在内。
<小时/> 例如，在gameObject.cpp中，您声明了GameObject类的函数，但是您没有包含gameobject.h，因此编译器找不到该类，这会导致错误。
