写了个装载显示xfile的类。有点问题
本帖最后由 kfbyj 于 2013-05-12 17:17:37 编辑 经常导入xfile 就写了个类
装载显示都正常。
为啥摄像机 一移动 用xfile类显示的物体也动。而且是和摄像机方向相反。
摄像机是按照 浅墨 博客里写的，应该没问题。
我写的这个类 也在 浅墨 的 代码里 移动摄像机 装载的物体也不会移动。。
很郁闷啊，找了一下午原因了！

先是全局申明
XFileObject *airplane;
然后init函数里
airplane = new XFileObject(g_pD3D9Dev);
airplane->InitXFile(L"airplane.x");
然后render函数里
D3DXMATRIX matAirplane;
D3DXMatrixTranslation(&matAirplane,-10.0f, 10000.0f,-10.0f);
airplane->RenderXFile(&matAirplane);
