This is a tool to generate map files for OpenFront.

Creating a new map

1. Create a new folder in assets/maps/<map_name>

3. Create info.json with name and countries
4. Add the map name in main.go
5. Run the generator: go run .
6. Find the output folder at generated/maps/<map_name>

Create image.png

1. Download world map (warning very large file) https://drive.google.com/file/d/1W2oMPj1L5zWRyPhh8LfmnY3_kve-FBR2/view?usp=sharing
2. Crop the file (recommend Gimp), we recommend roughly 2 million pixels for performance reasons. Do not go over 4 million pixels.

Create info.json

• Look at existing info.json for structure
• Use country codes found here: https://en.wikipedia.org/wiki/List_of_ISO_3166_country_codes

Notes

• Islands smaller than 30 tiles (pixels) are automatically removed by the script.
• Bodies of water smaller than 200 tiles (pixels) are also removed.
