Your first mod

A mod is a folder with a mod.json and some JSON files. No coding.

Try the example

  1. Get the example mod: examples/mods/small_imports in the game’s repository.
  2. Copy the folder into the game’s Content folder. On the main screen: New Game → Open the Content folder.
  3. Start the game. It adds four small European cars, their engines and speed parts, a shop, a car lot, a rival and a race night.

Make it yours

  1. Copy small_imports and rename the folder.
  2. In mod.json, change id, name and author. The id must be unique.
  3. Change or delete the files you don’t need.
{
  "id": "mymod",
  "name": "My Mod",
  "version": "1.0",
  "author": "you",
  "type": "addon"
}

If the game can’t read something, it tells you at start-up. The game’s log lists every mod it loaded.
