Hi, to generate map preview with command line I need to extract map_gen_settings.json from the Map exchange string

/c game.write_file('map.txt', game.table_to_json(game.parse_map_exchange_string("<your exchange string here>")))

this command is from your wiki
https://wiki.factorio.com/Command_line_parameters

When i run this command with my exchange string i get error:

Cannot execute command. Error: LuaGameScript doesnt contain key write_file.

This is not a bug, this function has been moved to helpers.

See https://lua-api.factorio.com/latest/cla ... write_file

Thanks, this commands works (changed game. to helpers. ):

Code: Select all

/c helpers.write_file('map.txt', helpers.table_to_json(helpers.parse_map_exchange_string(">>>MAP EXCHANGE STRING")))
