should I export my game as setup or as zip. if I want to upload it on Steam? And how do my Game connect with the steam function's? how should steam know if the Player should got know a archievment ? I know about the code command: "steam_get_achievement". But how should this commandline connect with the player his steam account? I think it need definitely more than only a codeline in my game to connect with the player steamaccount to unlock my archievment... but what do I all need for this and what do I need in addition everything if I want to publish my game on steam?
