Wannaroo Extra Industries (WRExInd)

NewGRF for OpenTTD - Extra industries for WRBI, can also be used with other industry sets. These are industries I've written for experimentation/testing/fun, but may be useful in your games.

  1. About

    Too many trees? The Lumber Mill will clear those for you. Need to chillax? Build a Distillery. Jonesing for a chemical fix? Your friendly Hydrocracking Plant has what you need. Too many town goods? Take them all to the Distribution Center. Reduce, reuse, recycle with the Recycling Depot and Plant.

  2. Compatibility

    Wannaroo Extra Industries should be compatible with other industry sets. However, no checks are carried out when starting a game. Load multiple industry sets at your own risk.

    I have spot-checked (but not extensively tested) with default OpenTTD industries, PBI, Manpower Industries, OpenGFX+ Industries, and FIRS 3 basic economies x3 with sensible results. Will work with Wannaroo Basic Industries (WRBI).

    Compatibility with any newgrf is not guaranteed. No warranties are expressed or implied.

    Not valid for Toyland.

    Requirements: OpenTTD 1.9.0 or later, vehicle sets that support new cargos.

  3. Features

    • 8 new industries:

      • Distribution Center 💰 : Accepts: food, goods, petrol, alcohol, building materials, engineering & farm supplies. Produces: nothing
      • Lumber Mill 🌲 : Copy of default lumber mill for tree growth control. Available in all climates. Enable if you need tree growth control or an industry to produce wood.
      • Distillery 🍺 : Accepts: grain | wheat | maize, fruit. Produces: alcohol
      • Hydrocracking Plant 🧪 : Accepts: waste | coal, oil, wood. Produces: chemicals, petrol. Dynamic output based on transported %
      • City Hall 🏛️ : Accepts & produces tourists (if present), otherwise passengers. Manual placement only. Displays town information for Pikka's TaI house set (version Gamma 1).
      • Desalination Plant 🚰 : Accepts: nothing. Produces: chemicals (temp, arctic) | water (tropic), stone | chemicals. Produced cargos will vary depending on your in-game industry set.
      • Recycling Chain (2 industries): ♻️ : Transport recyclables from the Depot to the Plant, then deal with the waste in order to produce steel | paper | copper. Waste transported % must be at least 65% to enable 2nd cargo production.
    • Parameters: hopefully are self-explanatory

  4. Development

    The usual pnml/nml files with C includes and macros. However, Distribution Center tweaks are done in nfo.

    1. run to generate the nfo file.
    2. copy/paste sprites from src/docs/distribution_center_nfo_tweaks.txt into the nfo file.
    3. run to generate the tar file.

    I built this newgrf on Linux Mint 19.3 using gcc version 7.5.0, NML version 0.4.5, and grfcodec version 6.0.6 r991.

    Translations gladly accepted. Please open an issue on GitHub ( and attach your lang file so I can include it in a release.
