    Overview · Install · Usage · File Support · Specification · Contributing · Special Thanks


    WC3MapTranslator is a TypeScript module to convert between JSON and WarCraft III (.w3x) war3map formats. This makes the map data readable and easily modifiable, a perfect format for storing WC3 maps in Git repositories and inspecting diffs!



    npm install wc3maptranslator

    Requires Node ≥ 14


    import {
    } from 'wc3maptranslator';
    // E.g. let's create a camera for the map
    const cameras = [
        "target": {
          "x": -319.01,
          "y": -90.18
        "offsetZ": 0,
        "rotation": 90,
        "aoa": 304,
        "distance": 2657.34,
        "roll": 5,
        "fov": 70,
        "farClipping": 5000,
        "name": "MyCamera1"
    // Now translate the JSON into the WarCraft III format
    // All translators have: `.jsonToWar` and `.warToJson` functions
    const translatedResult = CamerasTranslator.jsonToWar(cameras);
    // `translatedResult` contains a `buffer` which can be saved to disk
    // This war3map.w3c file can now be placed inside a .w3x via an MPQ
    // editor, and you should now see a camera in the Camera Palette!
    fs.writeFileSync('war3map.w3c', translatedResult.buffer);

    WC3MapTranslator format

    We have a detailed explaining how to format a map in JSON. It explains everything from the high-level map object, all the way down to creating individual units, tiles, or custom objects.

    🔗 WC3MapTranslator format

    war3map format

    The underlying WarCraft map files (e.g. war3map.doo) have been documented in a separate repository. If you are curious about how a .w3x file is composed, this is the place to learn!

    🔗 WC3MapSpecification


    We encourage contributions! Generally, the process of making a change is:

    1. Fork this repo
    2. Develop your changes on a new branch
    3. Submit a pull request to dev

    Your code should:

    • run (your code needs to work, of course)
    • include tests (write unit tests to demonstrate your code works under different conditions)
    • be linted (run npm run lint and follow the project's coding standards)
    • pass CI (we enforce: ESLint, unit tests pass, code coverage)

    A code review is required on your PR to be accepted into dev. A project member will get back to you within one week. If you haven't heard from someone regarding your PR, feel free to ping @chiefofgxbxl.

    Special Thanks

    We owe a lot of thanks to Chocobo on TheHelper for the detailed documentation of the files found in a .w3x archive. Two tutorials are here (1) and here (2).
