void EnemyModel::GetMesh(IDirect3DDevice9 *Device, LPCWSTR filename,LPWSTR Texturename)
{
   if(FAILED(D3DXLoadMeshFromX((filename), D3DXMESH_MANAGED, Device, &pAdjacencyBuffer, &pMaterialsBuffer, NULL, &numMaterials, &mesh)))
   {
       MessageBox(NULL, L"装入敌人.x文件失败", NULL, 1);
   }
   pD3DMaterial = (D3DXMATERIAL*)pMaterialsBuffer->GetBufferPointer();          //将材质与纹理缓冲区的地址赋给扩展后的材质缓冲区
   if(pD3DMaterial != NULL)
   {
       pMaterialsArray = new D3DMATERIAL9[numMaterials];
       pTextureArray = new IDirect3DTexture9*[numMaterials];
       LPWSTR RTexturefilename=Texturename;
       for(int i=0; i<(int)numMaterials; i++)
       {
           wchar_t str[1000]={0};
           pMaterialsArray[i] = pD3DMaterial[i].MatD3D;
           pMaterialsArray[i].Diffuse = CampusEngine_Common::WHITE;
           pMaterialsArray[i].Emissive = CampusEngine_Common::WHITE;

pMaterialsArray[i].Power = 1.0f;

//解决方法：通过主程序指明当前.x文件存放的上级目录，然后将纹理的名称添加到目录路径上，如：可以通过程序指明路径：media\DOOR\\,然后在for循环中动态添加纹理的名称如'qianzhuang.jpg'最终将两个字符串合并在一起，就得到了纹理的路径即：media\DOOR\qiangzhuang,jpg

           lstrcatW(str,RTexturefilename);
           //将LPSTR转化为宽字节解决纹理路径
           int dwNum=MultiByteToWideChar(CP_ACP,0,pD3DMaterial[i].pTextureFilename,-1,NULL,0);
           wchar_t *pwText=new wchar_t[dwNum];
           MultiByteToWideChar(CP_ACP,0,pD3DMaterial[i].pTextureFilename,-1,pwText,dwNum);

           lstrcatW(str, pwText);
           if(pD3DMaterial[i].pTextureFilename != 0)
           {
               if(FAILED(D3DXCreateTextureFromFile(Device,str, &pTextureArray[i])))//FilePahtName
               {
                   pTextureArray[i] = NULL;
                   RTexturefilename=Texturename;
               }
           }
           else
           {
               pTextureArray[i] = NULL;
           }
       }
   }
   else
   {   MessageBox(NULL, L"pD3DMaterial = NULL!", NULL, 1); }
   pAdjacencyBuffer->Release();
   pMaterialsBuffer->Release();
}
