The LambdaHack package

[Tags:bsd3, game, library, program, test]

This is an alpha release of LambdaHack, a roguelike game engine packaged together with a small example roguelike game (not yet well separated; this is future work, together with improving the AI monad EDSL, so that the rules for synthesising monster behaviour from game content are more readable and easier to debug).

Another game using this engine is Allure of the Stars at

Readme for LambdaHack

Readme for LambdaHack-0.1.20110918


LambdaHack is a small roguelike game written in Haskell. It is getting more and more configurable and aims to become a flexible rouguelike engine, suitable for large and small dungeon crawling games of arbitrary themes. In particular, we try to keep the AI code independent of particular monster, item and terrain definitions.

Compilation and installation

The game is best compiled and installed via Cabal, which also takes care of all dependencies. The latest official version of the game can be downloaded automatically by Cabal from Hackage as follows

cabal install LambdaHack

For a more current snapshot, download the source from github and run Cabal from the main directory

cabal install

or you may try one of the terminal frontends with

cabal install -fvty

Savegame directory

If you don't want LambdaHack to write to the current directory, create a personal savegame directory (on Linux it's ~/.LambdaHack/). and copy the scores file there. You may also want to copy the configuration file src/config.default to ~/.LambdaHack/config and modify it, but be careful changing gameplay options --- they can easily unbalance or break the game.
