libtcod is a fast, portable and uncomplicated API for roguelike developers providing an advanced true color console, input, and lots of other utilities frequently used in roguelikes.

SFML provides a simple interface to the various computer components, to ease the development of games and multimedia applications. It is composed of five modules: system, window, graphics, audio and network.

Allegro is a library mainly aimed at video game and multimedia programming. It handles common, low-level tasks such as creating windows, accepting user input, loading data, drawing images, playing sounds, etc.

go-sdl2 is SDL2 wrapped for Go users. It enables interoperability between Go and the SDL2 library which is written in C. That means the original SDL2 installation is required for this to work.

catcodec encodes and decodes sounds for OpenTTD. These sounds are not much more than some metadata (description and filename) and raw PCM data.

BBC BASIC is the programming language originally specified and adopted by the British Broadcasting Corporation for its groundbreaking Computer Literacy Project of the early 1980s. BBC BASIC for SDL 2.0 combines the simplicity of BASIC with the sophistication of a modern structured language, allowing you to write utilities and games, use sound and graphics, perform calculations and create complete applications.

This package provides the standard library for Inform 6.

This repository contains CMake modules which are used across Shlomi Fish's projects.

Ren'Py is a visual novel engine that helps you use words, images, and sounds to tell interactive stories that run on computers and mobile devices. These can be both visual novels and life simulation games. The easy to learn script language allows anyone to efficiently write large visual novels, while its Python scripting is enough for complex simulation games.

OpenMW is a game engine which reimplements and extends the one that runs the 2002 open-world RPG Morrowind. The engine comes with its own editor, called OpenMW-CS which allows the user to edit or create their own original games.

Originally inspired by Unity IMGUI (immediate mode GUI API).

Designed as an auxiliary module for raylib to create simple GUI interfaces using raylib graphic style (simple colors, plain rectangular shapes, wide borders...) but it can be adapted to other engines/frameworks.

Chipmunk is a simple, lightweight, fast and portable 2D rigid body physics library written in C.

The OpenGL Character Renderer (GLC) is a state machine that provides OpenGL programs with character rendering services via an application programming interface (API).

This package provides an interactive tutorial for the Ren'py visual novel engine, explaining all of its features.

DDS is a double-dummy solver of bridge hands. It supports single-threading and multi-threading for improved performance. DDS offers a wide range of functions, including par-score calculations.

rpatool is a simple tool allowing you to create, modify and extract Ren'Py Archive files (.rpa/.rpi). Currently, only writing RPAv2/RPAv3 archives is supported.

This package provides a game networking framework for Python.

Box2D is a 2D rigid body simulation library for games. Programmers can use it in their games to make objects move in realistic ways and make the game world more interactive. From the game engine's point of view, a physics engine is just a system for procedural animation.

Rinutils is a set of C headers containing macros and static functions that have been extracted from Shlomi Fish's projects.

SurgeScript is a dynamically typed object-oriented scripting language designed for games. Each object is a state machine that can be customized by attaching other objects. The language supports automatic garbage collection and can be extended with plugins.

Cross Platform Object Oriented Input Lib System is a cross platform, simple solution for using all kinds of Input Devices (Keyboards, Mice, Joysticks, etc) and feedback devices (e.g. force feedback). Meant to be very robust and compatible with many systems and operating systems.

Eureka is a map editor for the classic DOOM games, and a few related games such as Heretic and Hexen. It comes with a 3d preview mode and a 2D editor view.

DeuTex is a wad composer for Doom, Heretic, Hexen and Strife. It can be used to extract the lumps of a wad and save them as individual files. Conversely, it can also build a wad from separate files. When extracting a lump to a file, it does not just copy the raw data, it converts it to an appropriate format (such as PPM for graphics, Sun audio for samples, etc.). Conversely, when it reads files for inclusion in pwads, it does the necessary conversions (for example, from PPM to Doom picture format). In addition, DeuTex has functions such as merging wads, etc.

Pybox2d is a 2D physics library for your games and simple simulations. It's based on the Box2D library, written in C++. It supports several shape types (circle, polygon, thin line segments), and quite a few joint types (revolute, prismatic, wheel, etc.).
