        That's the function you call between gym.make() and first env.reset(), to connect to multiplayer server.

        game_server_guid -- is an id that server and client use to identify themselves to belong to the same session.
        player_n -- integer, up to scene.players_count.

        You see here env._reset() gets overwritten, that means if you call env.reset(), it will not create
        single player scene on your side (as it usually do), but rather it will communicate to server, reset environment
        there. Same with step() and render().
