Contribs are found in evennia/contrib/ and are optional game-specific code-snippets or even full systems you can use for your game. They are contributed by the Evennia community and released under the same license as Evennia itself. Each contrib has its own installation instructions. Bugs are reported to the Evennia issue tracker as usual.

Build a game area based on a 2D “graphical” unicode map. Supports asymmetric exits.
Example of an exit that can be opened and closed from both sides.
Custom Exit class that takes different time to pass depending on if you are walking/running etc.
Make infinitely large wilderness areas with dynamically created locations.

Evennia community 2015-?
This is a community attempt to make an Evennia ‘example game’ using good practices. It is also a good place to jump in if you want to help in another project rather than run it alone. Development of this has stalled a bit so we are looking for enthusiastic people to lead the charge.
Open source code release of the popular Evennia-based Arx, after the reckoning. This is a fantasy game with a focus on roleplay and code-supported political intrigue. This code-release is maintained by Tehom in its own repository so bug reports should be directed there.
A full engine for making multiplayer ‘escape-rooms’ completely in code. This is based on the 2019 MUD Game jam winner Evscaperoom.
contrib/evscaperoom - game engine to make your own escape rooms.
https://demo.evennia.com - a full installation of the original game can be played by entering the evscaperoom exit in the first Limbo room.
https://github.com/Griatch/evscaperoom - the original game’s source code (warning for spoilers if you want to solve the puzzles and mystery yourself).
