Question

因此，我正在使用olcConsoleGameEngine（由于其太大而无法复制粘贴https://github.com/OneLoneCoder/videos/blob/master/olcConsoleGameEngine.h），并且我正在使用从其继承的类作为游戏的基础，这是头文件：

Game.h

#ifndef GAME_H
#define GAME_H

#include "olcConsoleGameEngine.h"

class Game : public olcConsoleGameEngine
{
public:
    Game();

protected:
    /*
    virtual bool OnUserCreate()
    {
        return true;
    }

    virtual bool OnUserUpdate(float fElapsedTime)
    {
        Fill(0, 0, ScreenWidth(), ScreenHeight(), PIXEL_SOLID, FG_BLUE);
        return true;
    }
    */
    virtual bool OnUserCreate();
    virtual bool OnUserUpdate(float fElapsedTime);
};

#endif

注意注释，声明和定义这种方式是到目前为止我唯一可以编译的方式（确保同时删除cpp中的声明）

Game.cpp

#include "Game.h"

Game::Game()
{
}

bool Game::OnUserCreate()
{
    return true;
}

bool Game::OnUserUpdate(float fElapsedTime)
{
    return true;
}

总的来说，我只有用于设置窗口的标准代码，因为在.h中声明Update和Create函数的工作没有错误并且给出了正确的输出，所以我知道这是有效的。似乎一旦我在Game.cpp中包含Game.h，我就会得到链接器错误，即：

1>main.obj : error LNK2005: "void __cdecl GetFontCoords(int,int *,int *)" (?GetFontCoords@@YAXHPAH0@Z) already defined in Game.obj
1>main.obj : error LNK2005: "void __cdecl font_decode_custom_base64(void)" (?font_decode_custom_base64@@YAXXZ) already defined in Game.obj

1>C:\Dev\C++Projects\WarAutomata\Debug\WarAutomata.exe : fatal error LNK1169: one or more multiply defined symbols found

Main.cpp

#include "Game.h"

int main() {
    Game game;
    game.ConstructConsole(640, 480, 1, 1);
    game.Start();
    return 0;
}

所以在程序的当前状态下，我将在头文件中声明每个函数，这显然不是理想的选择。对这个问题的任何帮助将不胜感激。
