各位大哥，我是新手想请教个问题，为什么我在绘制2d图片前面调用Setup2DCamera后，图片是跟着窗口在走，但是我的鼠标拾取检测就失效，如果我把他注掉。鼠标拾取就可以检测，什么原因啊，我想了好长时间还是不会，大哥们快帮帮我
void CRPGCamera::Setup2DCamera(LPDIRECT3DDEVICE9 pD3DDevice)
{
        D3DXMATRIX matOrtho;       
        D3DXMATRIX matIdentity;

        //Setup the orthogonal projection matrix and the default world/view matrix
        D3DXMatrixOrthoLH(
                &matOrtho,
                (float)640,
                (float)480,
                0.0f, 1.0f);
        D3DXMatrixIdentity(&matIdentity);

        pD3DDevice->SetTransform(D3DTS_PROJECTION, &matOrtho);
        pD3DDevice->SetTransform(D3DTS_WORLD, &matIdentity);
        pD3DDevice->SetTransform(D3DTS_VIEW, &matIdentity);

        //Make sure that the z-buffer and lighting are disabled
        pD3DDevice->SetRenderState(D3DRS_ZENABLE, D3DZB_FALSE);
        pD3DDevice->SetRenderState(D3DRS_LIGHTING, FALSE);
}
