automatic map generation

Post by gheift »

Based on a reddit thread I created a script, which creates screenshot of maps on linux.

The script creates a screenshot of a new generated map in the script-output directory. The current format is netpbm ppm and can be converted to jpeg or png, if the netpbm is installed. To do this after the generation, just uncomment the commands in ./map-gen.sh.

Since the game does not provide a function to generate a screenshot of the map (at least I do not found one), I implemented it myself in lua. Therefore there are currently no nests and trees on the map.

To use it you do the following:
  • download the headless server from https://www.factorio.com/download-headless/experimental
  • unpack it somewhere
  • download the attached script
  • unpack the content in the directory of the headless server, this will overwrite data/base/scenarios/freeplay/control.lua
  • open a terminal and change into the directory of the headless server
  • run ./map-gen.sh
  • Profit!
This takes around 30 to 45 seconds and will (hopefully) produce output like this:

Code: Select all

I am aware of this command, but AFAIK you can not create an image of the map with it. If you set the zoom to 1/32 (1 pixel per tile) the result is much noisier than the map. Here is the result of the seed I used above:
