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

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.

CSFML is the official C binding to the SFML libraries. 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.

Flatzebra is a simple, generic C++ game engine library supporting 2D double-buffering.

Chickadee is a game development toolkit for Guile Scheme built on top of SDL2 and OpenGL. Chickadee aims to provide all the features that parenthetically inclined game developers need to make 2D (and eventually 3D) games in Scheme, such as:

1. extensible, fixed-timestep game loop

2. OpenGL-based rendering engine

3. keyboard, mouse, controller input

4. REPL-driven development model

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.

Godot is an advanced multi-platform game engine written in C++. If features design tools such as a visual editor, can import 3D models and provide high-quality 3D rendering, it contains an animation editor, and can be scripted in a Python-like language.

This package contains a collection of modules for the Bennu Game Development programming language, from CD handling through SDL to joystick support.

This package provides physfssdl3.c and its header, which implement SDL3's SDL_IOStream and SDL_Storage interfaces using PhysicsFS as the backend. It enables SDL3 applications to load assets from compressed archives and other PhysicsFS-supported storage through the standard SDL3 API.

This package contains the game engine of Tesseract, a first-person shooter focused on cooperative in-game map editing.

The engine is derived from Cube 2: Sauerbraten technology but with upgraded modern rendering techniques. The new rendering features include fully dynamic omnidirectional shadows, global illumination, HDR lighting, deferred shading, morphological / temporal / multisample anti-aliasing, and much more.

Recast is state of the art navigation mesh construction toolset for games.

• It is automatic, which means that you can throw any level geometry at it and you will get robust mesh out.

• It is fast which means swift turnaround times for level designers.

The Recast process starts with constructing a voxel mold from a level geometry and then casting a navigation mesh over it. The process consists of three steps, building the voxel mold, partitioning the mold into simple regions, peeling off the regions as simple polygons.

Recast is accompanied with Detour, path-finding and spatial reasoning toolkit. You can use any navigation mesh with Detour, but of course the data generated with Recast fits perfectly.

Detour offers simple static navigation mesh which is suitable for many simple cases, as well as tiled navigation mesh which allows you to plug in and out pieces of the mesh. The tiled mesh allows you to create systems where you stream new navigation data in and out as the player progresses the level, or you may regenerate tiles as the world changes.

Hex-a-hop is a puzzle game in which a girl has to destroy green hexagons by stepping on them.

NetPanzer is an online multiplayer tactical warfare game. It is based on quick tactical action and unit management in real-time. Battles progress constantly as destroyed players respawn with a set of new units. Players can join or leave multiplayer games at any time.

The GNU Talk Filters are programs that convert English text into stereotyped or otherwise humorous dialects. The filters are provided as a C library, so they can easily be integrated into other programs.

Unknown Horizons is a 2D realtime strategy simulation with an emphasis on economy and city building. Expand your small settlement to a strong and wealthy colony, collect taxes and supply your inhabitants with valuable goods. Increase your power with a well balanced economy and with strategic trade and diplomacy.

The Powder Toy is a free physics sandbox game, which simulates air pressure and velocity, heat, gravity and a countless number of interactions between different substances! The game provides you with various building materials, liquids, gases and electronic components which can be used to construct complex machines, guns, bombs, realistic terrains and almost anything else. You can then mine them and watch cool explosions, add intricate wirings, play with little stickmen or operate your machine.

Enigma is a puzzle game with 550 unique levels. The object of the game is to find and uncover pairs of identically colored ‘Oxyd’ stones. Simple? Yes. Easy? Certainly not! Hidden traps, vast mazes, laser beams, and most of all, countless hairy puzzles usually block your direct way to the Oxyd stones. Enigma’s game objects (and there are hundreds of them, lest you get bored) interact in many unexpected ways, and since many of them follow the laws of physics (Enigma’s special laws of physics, that is), controlling them with the mouse isn’t always trivial.

This package provides Tcl/Tk Go bindings, the API is a bit Tk-oriented.

Blobwars: Metal Blob Solid is a 2D platform game, the first in the Blobwars series. You take on the role of a fearless Blob agent. Your mission is to infiltrate various enemy bases and rescue as many MIAs as possible, while battling many vicious aliens.
