MapGenerator

This is a tool to generate map files for OpenFront.

Installation

  1. Install go https://go.dev/doc/install
  2. Install dependencies: go mod download
  3. Run the generator: go run .

Creating a new map

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

Notes

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