我有一个游戏课-

游戏.h：

#pragma once

#include "D3DGraphics.h"
#include "Mouse.h"
#include "Screen.h"
#include "Script.h"

class Game
{
public:
    Game( HWND hWnd, const MouseServer &mouseServer, const ScreenServer &screenServer );
    void Go();
    void Config();

private:    
    void ComposeFrame();

    D3DGraphics gfx;
    MouseClient mouse;
    ScreenClient screen;

    Script * scripts[ 1 ];
};

我有一个 D3DGraphics 类-

D3DGraphics.h：

#pragma once

#include <d3d9.h>
#include <d3dx9.h>

#include "Screen.h"
#include "Script.h"

#define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE)

struct CUSTOMVERTEX
{
    FLOAT x, y, z, rhw;    // from the D3DFVF_XYZRHW flag
    DWORD color;    // from the D3DFVF_DIFFUSE flag
};

class D3DGraphics
{
public:
    D3DGraphics( HWND hWnd, ScreenClient screenClient );
    ~D3DGraphics();

    void Begin();
    void End();
    void Present();

    void CreateViewport();
    void DefineText( Script *script );

    LPDIRECT3D9 d3dObject;
    LPDIRECT3DDEVICE9 d3dDevice;
    D3DPRESENT_PARAMETERS presParams;
    HRESULT hr;

    float ResizeLockRatio( float width, float height, float scalingWidth );
    float GetGameOffset( float resizedImageHeight );

    void DrawRectangle( int x, int y, int width, int height, D3DCOLOR backgroundColor );
    void DrawActionBar();
    void RenderText( Script *script );
private:
    LPDIRECT3DVERTEXBUFFER9 vBuffer;
    ScreenClient screen;
};

请注意，Game 类同时具有

D3DGraphics gfx;
Script * scripts[ 1 ];

在我的 Game.cpp 中，我制作了一个 D3DGraphics 版本并将其放在 gfx 中：

游戏.cpp：

#include "Game.h"

Game::Game( HWND hWnd, const MouseServer &mouseServer, const ScreenServer &screenServer )
    :   mouse( mouseServer ),
        screen( screenServer ),
        gfx( hWnd, screen )
{
    //gfx.d3dDevice->SetRenderState( D3DRS_ALPHABLENDENABLE, TRUE);

    std::string debugStringResult;
    std::stringstream debugString;
    debugString << "Mouse X: " << mouse.GetMouseX() << ",\nMouse Y: " << mouse.GetMouseY() << ",\nLeft mouse down: " << mouse.LeftMouseDown() << ",\nRight mouse down: " << mouse.RightMouseDown() << ",\nScreen width: " << screen.GetScreenWidth() << ",\nScreen height: " << screen.GetScreenHeight() << "\nSystem resolution: " << screen.GetWindowWidth() << " x " << screen.GetWindowHeight();
    debugStringResult = debugString.str();
        scripts[ 0 ] = new Script( gfx, "Arial", 0, 0, 255, 0, debugStringResult, 10, 10, ( screen.GetWindowWidth() - 10 ), ( screen.GetWindowHeight() - 10 ) );
}

我有一个脚本课-

脚本.h：

#pragma once

#include "D3DGraphics.h"
#include <sstream>

class Script
{
public: 
    Script( D3DGraphics gfx,
            LPCSTR font, 
            int alpha, int r, int g, int b, 
            std::string text, 
            float x, float y, float width, float height );

    LPCSTR font;
    int alpha, r, g, b;
    std::string text;
    float x, y, width, height;
    D3DCOLOR color;
    RECT rect;
    ID3DXFont *handle;
private:
};

我的脚本构造函数如下所示：

脚本.cpp：

#include "Script.h"

Script::Script( D3DGraphics gfx,
                LPCSTR font, 
                int alpha, int r, int g, int b, 
                std::string text, 
                float x, float y, float width, float height )
{
    gfx.DefineText( this );
}

等等。现在，当我编译我的应用程序时出现错误：

Error   1   error C2061: syntax error : identifier 'D3DGraphics'    c:\users\james\documents\visual studio 2012\projects\thegame\thegame\script.h   9   1   TheGame

Script.h 的第 9 行是：

Script( D3DGraphics gfx,...

老实说，我不知道到底发生了什么？有人知道吗，在过去的 2 个小时里，我一直在像死动物一样戳代码。

正如Need4Sleep 所提到的，您对D3DGraphics.hand的循环包含Script.h是问题所在。解决此问题的一种方法是仅转发声明您的脚本类，而不是将其标头包含在D3DGraphics.h.

例如：

#pragma once

#include <d3d9.h>
#include <d3dx9.h>

#include "Screen.h"

#define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE)

class Script;
struct CUSTOMVERTEX
{
    FLOAT x, y, z, rhw;    // from the D3DFVF_XYZRHW flag
    DWORD color;           // from the D3DFVF_DIFFUSE flag
};

class D3DGraphics
{
public:
    D3DGraphics( HWND hWnd, ScreenClient screenClient );
    ~D3DGraphics();

    // rest of D3DGraphics's definition
};

只要D3DGraphics没有Script以实质性方式使用您的类的内联方法，这将起作用。例如。指向脚本的指针很好。

你有一个循环依赖，所以你可能需要指定你想要在脚本之前编译 D3DGraphics，这是通过以下方式完成的：

#pragma once

#include "D3DGraphics.h"
#include <sstream>

class D3DGraphics;

class Script
{
public: 
    Script( D3DGraphics gfx,
            LPCSTR font, 
            int alpha, int r, int g, int b, 
            std::string text, 
            float x, float y, float width, float height );

    LPCSTR font;
    int alpha, r, g, b;
    std::string text;
    float x, y, width, height;
    D3DCOLOR color;
    RECT rect;
    ID3DXFont *handle;
private:
};
