避免多个标头定义

Question

我花了两天时间研究,以避免一些数组的多重定义,我发现#ifdef并bla bla.所以我尝试使用它来测试我的程序,#ifdef它没有做任何事情,调试器仍然说有多个定义.我的程序就是这样的.

当然有多个定义,但我需要像我在图片中向您展示的那样...我认为这是编译器问题或与编译器有关的事情.

PD:我想你不需要任何代码来解决我的问题,如果你需要我会分享.

将定义放入cpp文件中.如果将它们放到标题中,它们将在包含标题的每个cpp文件中定义.

GameObject.h

#ifndef GAMEOBJECT_H
#define GAMEOBJECT_H

extern float cube[];
...
typedef struct GameObject
{
    int ID, parent;
    Vector3 position;
    Quaternion rotation;
};

extern GameObject GameObjects[65536];
...
#endif

GameObject.cpp

#include "GameObject.h"

float cube[] = {...};
...
GameObject GameObjects[65536];
