I’m trying to write a game using steamworks, based on provided example SpaceWars. But there is not mouse action support, and i failed to introduce it. I rewrote steam_controller.vdf, added action handlers, but nothing works. Functions like SteamInput( )->GetDigitalActionData() always return false and SteamInput( )->GetConnectedControllers return 0, so it does not recognize mouse at all. What is the correct way to deal with mouse actions?
