在directx中应用纹理时存在巨大问题9 C++

我在编译我的游戏时没有遇到任何错误。唯一的问题是它不会应用纹理，而是应用一种颜色（我知道它很奇怪）。如果纹理有白色和红色两种颜色，则会应用白色。在directx中应用纹理时存在巨大问题9 C++

这里是我的代码

你的问题是你根本就不使用声明textured_vertex和使用CUSTOMVERTEX代替。由于CUSTOMVERTEX只包含颜色信息，这是很明显，你会得到什么结果:)我建议扩大CUSTOMVERTEX结构是这样的：

struct CUSTOMVERTEX 
{ 
    FLOAT x, y, z; // from the D3DFVF_XYZRHW flag 
    DWORD color; // from the D3DFVF_DIFFUSE flag 
    FLOAT tx, ty; // from the D3DFVF_TEX1 flag 
};

也改变了定义CUSTOMFVF的匹配结构：

#define CUSTOMFVF (D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1)

此外，全球阵列CUSTOMVERTEX vertices[500]似乎完全没有使用，删除它，以便它在未来不会导致不需要的行为。对于未使用的textured_vertex结构也是如此。

嗯，我做了你说的，但我仍然有相同的结果 – Ramilol 2010-09-27 22:01:05

我想你还添加了纹理坐标到顶点数组定义？现在只有位置和颜色，你应该把另外两个数字作为纹理坐标：'{-3.0f，3.0f，-3.0f，D3DCOLOR_XRGB（0,0,255），1.0f，1.0f}' – 2010-09-27 22:08:09

我做了对于每一个但仍然是相同的结果检查新代码 – Ramilol 2010-09-27 22:19:30
