Modding tutorial for KeeperRL (Overview)

  • The first recommendation is to get familiar with the existing modding system on KeeperRL
  • There are two types of mod on KeeperRL
    • Local mods (Edit the official game files locally) - Can't be uploaded onto the Web. Easier to learn for beginners.
    • Web mods (Write new mod files that modify, replace or append to the official game files) - Slightly tougher but you can upload them for other players to use.
  • Make some simple changes to the vanilla files, that is the official files (Try some of the suggestions below) and test the changes. Vanilla configs are found under "KeeperRL\datafree\gamedata\*.txt"
Note, when changing vanilla configs you need to back them up in case you damage them
  • After learning to do local mods, install some existing Web Mods
  • Test them
  • Start writing your own Web mods

Setting your own targets

  • Set yourself some simple targets for local modding.
  • Look at some of the other moddable text files. Gain familiarity.
  • After that, download a web mod and try and understand how it works.
  • After that hack the web mod (You can hack any of mine, I don't mind - SoftMonster 17.09.2020 - but parallel uploads are annoying - don't)
  • After that write your own web mod from scratch and upload it for the player community to show you the respect you deserve!

Good luck!
