不能运行是什么反应？
是点击后没反应还是出错？

[heavenchang]

对呀

要你错的信息呀

[Boor]

wlpwind(robin) :是点击程序没反应
也没有出错信息....

[chena224503]

可能是你还没有创建窗口，程序就退出了。
单步调试。

[gcz5212314]

怪哉！怪哉！！

[Boor]

单步在调用InitD3D( hWnd )的时候异常退出了,不会跟硬件有关吧,我的显卡是NVIDIA RIVA TNT2 MODEL 64 PRO...
nnd..who da xia can help me?

[gcz5212314]

我试着编译了一下，也和搂主出现的情况一样。
后来我试着单步执行，执行到这一步时怎么也进不去，
if( SUCCEEDED( InitGeometry() ) ，后来我仔细看一下InitGeometry()这个函数，终于发现了问题
D3DXCreateTextureFromFile( g_pd3dDevice, filename, &g_pMeshTextures[i] )
这个函数的filename在整个程序中始终没有给出！！！

[GameWeaverDummy]

顶

[Boor]

to:gcz5212314(孤独一剑)在那个函数的上面第二行就是, char filename[].
看来我还是在翻翻DIRECTX 的文档吧...大家都好菜哦...

[Boor]

wsm 我的显卡不支持硬件顶点运算??痛苦中.....
把D3DCREATE_HARDWARE_VERTEXPROCESSING改为D3DCREATE_SOFTWARE_VERTEXPROCESSING就搞定了....就是运行起来像蜗牛爬:)

楼下的只要跟贴都有分啊~~~~~~~~
