The LambdaHack package

[Tags: bsd3, library, program]

This is an alpha release of LambdaHack, a game engine library for roguelike games of arbitrary theme, size and complexity, packaged together with a small example dungeon crawler. When completed, the engine will let you specify content to be procedurally generated, define the AI behaviour on top of the generic content-independent rules and compile a ready-to-play game binary, using either the supplied or a custom-made main loop. Several frontends are available (GTK is the default) and many other generic engine components are easily overridden, but the fundamental source of flexibility lies in the strict and type-safe separation of code and content.

New in this release are the Main Menu and the improved and configurable mode of squad combat. Upcoming new features: playable monsters faction, more than two factions inhabiting the dungeon, AIvAI, PvP, improved ranged combat AI, dynamic light sources, explosions player action undo/redo, completely redesigned UI. Long term goals are focused around procedural content generation and include in-game content creation, auto-balancing and persistent content modification based on player behaviour.

A larger game that depends on the LambdaHack library is Allure of the Stars, available from

Note: All modules in the library are kept visible, to let games override each, but reuse as many as possible. OTOH, to reflect that some modules are implementation details relative to others, the source code adheres to the following convention. If a module has the same name as a directory, the module is the exclusive interface to the directory. No references to the modules in the directory are allowed except from the interface module.
