【DirectDraw游戏汉化 #2】静物前传（Post Mortem）寻找CreateSurface

shane007 · 发表于 2023-8-25 16:59

这游戏以前分析过，本贴再写得详细一些。
这是一个DirectDraw游戏，在Post Mortem\Dlls下的DX7SoundManager.dll里完成对DirectDraw的初始化，
注意，初始化不是用导入函数方式进行，而是以loadlibrary方式进行的。

参考DDRAW.H得知CreateSurface是其中第7个函数，则函数偏移量为4X(7-1)=24,就是0x18.

STDMETHOD(CreateSurface)(THIS_ LPDDSURFACEDESC, LPDIRECTDRAWSURFACE FAR *, IUnknown FAR *) PURE;

复制代码

以下一段中完成CreateSurface。
