The VGUI fire button creates a "fire_mortar" event, which does nothing on client. We can fire this event from the server, the big issue is finding correct coordinates, which are clientside.

If m_hPlayerOwner is populated, then we could perhaps do vector math based on where the player is aiming and firing the server event by checking whether if the attack flag was pressed.
