I am have trouble rotating XFiles here is the code i have D3DXMatrixIdentity(&m_WorldMat); // Rotate around Y D3DXMatrixRotationY(&m_RotateY, Yaw); // Combine the matrix together m_WorldMat = m_RotateY * m_WorldMat; // Translate into position D3DXMatrixTranslation(&m_WorldMat, Pos3d.x, Pos3d.y, Pos3d.z); anyone got any ideas?? cheers

// Translate into position
D3DXMatrixTranslation(&m_WorldMat, Pos3d.x, Pos3d.y, Pos3d.z);

When you do that, I _think_ that it overwrites what is currently in m_WorldMat. So you should probably (not sure) do it like this:


D3DXMatrixIdentity(&m_WorldMat);

// Rotate around Y
D3DXMatrixRotationY(&m_RotateY, Yaw);

// Translate into position
D3DXMatrixTranslation(&m_WorldMat, Pos3d.x, Pos3d.y, Pos3d.z);

// Combine the matrix together
m_WorldMat = m_RotateY * m_WorldMat;


And then SetTransform( D3DTS_WORLD, &m_WorldMat ).

Try that, it might just work!
