c++ - Direct3D9 EndScene 钩子(Hook)渲染

Question

我正在使用 vTable Hook 挂接 Directx9 游戏。到目前为止，我已经能够成功地 Hook “Present”和“EndScene”(当然还有 CreateDevice 和 Direct3dCreate9)，但是 - 这就是陷阱 - 只要我尝试实际绘制任何东西(例如，文本), 我的 Present hook 不再被击中。 (这可能是内置的安全例程……我不太确定)。

例如...下面的代码有效

HRESULT APIENTRY hook_EndScene(IDirect3DDevice9* pInterface){   
    pInterface->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(255, 255, 255), 1.0f, 0);
    return orig_EndScene(pInterface);
}

导致屏幕永久显示白色。但是，尝试呈现文本(在 CreateDevice Hook 中创建的字体，使用返回的 IDirect3DDevice9 指针 - 我已确保使用 __asm pushad 和 popad 来恢复寄存器)或 Sprite ，导致 EndScene Hook 根本不再被击中.

我想知道是否需要任何特殊代码来确保 EndScene Hook 工作...以及为什么我可以清除屏幕，但一旦我想向它呈现额外的内容... Hook 不再起作用(不再命中断点)。文本确实呈现成功……一瞬间，然后被 Bink 视频替换……在这种情况下 Hook 不再起作用。

我完全一无所知...希望能为更有经验的 DirectX 编码人员提供一些帮助。谢谢。

编辑这是我的 CreateDevice Hook 以防万一

HRESULT APIENTRY hook_CreateDevice(IDirect3D9* pInterface, UINT Adapter,D3DDEVTYPE DeviceType,HWND hFocusWindow,DWORD BehaviorFlags,D3DPRESENT_PARAMETERS* pPresentationParameters,IDirect3DDevice9** ppReturnedDeviceInterface){

HRESULT ret = orig_CreateDevice(pInterface, Adapter, DeviceType, hFocusWindow, BehaviorFlags, pPresentationParameters, ppReturnedDeviceInterface);
__asm pushad
IDirect3DDevice9* d3ddev = *ppReturnedDeviceInterface;
D3DXCreateFont(d3ddev, 30, 0, FW_NORMAL,1,  false,  DEFAULT_CHARSET, OUT_DEFAULT_PRECIS,  DEFAULT_QUALITY,DEFAULT_PITCH | FF_DONTCARE, "Arial", &lpfont);   
//We have located the d3ddevice pointer. Now we can hook it!
DWORD* vTable = (DWORD*)*((DWORD*)d3ddev);
HookVTableFunc(vTable, (void*)&hook_EndScene, (void*)&orig_EndScene, 42);
__asm popad
return ret;

}

并且 EndScene Hook 不起作用(完全破坏 Hook ):

LPD3DXFONT lpfont;
HRESULT APIENTRY hook_EndScene(IDirect3DDevice9* pInterface){


static RECT textbox; SetRect(&textbox, 0, 0, 640, 480); 
lpfont->DrawTextA(NULL, "Testing", 22, &textbox, 0, D3DCOLOR_ARGB(0,255,255,255));
return orig_EndScene(pInterface);

}

它对我有用，我认为问题是你将 alpha 设置为 0？

我的 Hook 代码生成这些变量

• fIDirect3DDevice9_EndScene函数指针类型
• foIDirect3DDevice9_EndScene指向原始函数的函数指针
• fhIDirect3DDevice9_EndScene指向替换函数的函数指针
• vtIDirect3DDevice9_EndSceneEndScene 的 VTable 相关

使用这些命名方案，其余函数也可以由宏自动生成。

实际示例/ Hook (适用于 32 位和 64 位):

LPD3DXFONT g_Font;
D3DXFONT_DESC FontDesc = {24,
                          0,
                          400,
                          0,
                          false,
                          DEFAULT_CHARSET,
                          OUT_TT_PRECIS,
                          CLIP_DEFAULT_PRECIS,
                          DEFAULT_PITCH,
                          "Arial"};

void initHook() {
    IDirect3DDevice9* pD3DDevice = .. you got this one
    hookVT(pD3DDevice, IDirect3DDevice9, EndScene);
    D3DXCreateFontIndirect(pD3DDevice, &FontDesc,&g_Font);
}

#undef METHOD
#undef INTERFACE

#define INTERFACE IDirect3DDevice9
#define METHOD EndScene
GEN_HOOK(INTERFACE FAR* This)
{   
    static RECT textbox;
    SetRect(&textbox, 5, 0, 640, 480); 
    g_Font->DrawTextA(NULL, "Testing sadsadsad asd sadas asd sad sad as das dsadas dsa dsadas dasd ", -1, &textbox, DT_CENTER, 0xffffffff);

    CALL_ORGINAL();

    return hr;
}
#undef METHOD

我为此工作创建了一些辅助函数/宏:

template<typename func, typename vttype> void changeVTEx(void** vt, vttype n, func target)
{
    DWORD OldProtections = 0;
    VirtualProtect(&vt[n], sizeof(LPCVOID), PAGE_EXECUTE_READWRITE, &OldProtections);
    vt[n] = (void*)target;
    VirtualProtect(&vt[n], sizeof(LPCVOID), OldProtections, &OldProtections);
}

// preprocessor tools
#define PPCAT_NX(A, B) A ## B
#define PPCAT(A, B) PPCAT_NX(A, B)

#define getVT(ptr) (*(void***)ptr)
#define changeVT(n, target) changeVTEx(getVT(This), n, target)

#define hookVT(ptr, INTERFACE, METHOD) \
{\
    PPCAT(PPCAT(PPCAT(fo, INTERFACE),_), METHOD) = (PPCAT(PPCAT(PPCAT(f, INTERFACE), _), METHOD))(getVT(ptr)[PPCAT(PPCAT(PPCAT(vt, INTERFACE),_), METHOD)]);\
    changeVTEx(getVT(ptr), PPCAT(PPCAT(PPCAT(vt, INTERFACE),_), METHOD), PPCAT(PPCAT(PPCAT(fh, INTERFACE),_), METHOD));\
}

#define GEN_HOOK_(TYPE, ...) \
    PPCAT(PPCAT(PPCAT(f, INTERFACE), _), METHOD) PPCAT(PPCAT(PPCAT(fo, INTERFACE),_), METHOD) = NULL;\
    TYPE STDMETHODCALLTYPE PPCAT(PPCAT(PPCAT(fh, INTERFACE),_), METHOD)(__VA_ARGS__)

#define GEN_HOOK(...) \

#define UNHOOK \
    changeVT(PPCAT(PPCAT(PPCAT(vt, INTERFACE),_), METHOD), PPCAT(PPCAT(PPCAT(fo, INTERFACE),_), METHOD))

#define CALL_ORGINAL_(RET, ...) \
