Jolt Physics is a multi core friendly rigid body physics and collision detection library, written in C++. It is suitable for games and VR applications.

Dialog is a domain-specific language for creating works of interactive fiction. It is heavily inspired by Inform 7 and Prolog.

The Graphics Resource File (GRF) development tools are a set of tools for developing (New)GRFs. It includes a number of smaller programs, each with a specific task:

1. grfcodec decodes and encodes GRF files for OpenTTD.

2. grfid extracts the so-called "GRF ID" from a GRF.

3. grfstrip strips all sprites from a GRF.

4. nforenum checks NFO code for errors, making corrections when necessary.

PLIB is a set of libraries that will permit programmers to write games and other realtime interactive applications that are 100% portable across a wide range of hardware and operating systems. PLIB includes sound effects, music, a complete 3D engine, font rendering, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a collection of handy utility functions. All are 100% portable across nearly all modern computing platforms. Each library component is fairly independent of the others

Tiled is a general purpose tile map editor. It is meant to be used for editing maps of any tile-based game, be it an RPG, a platformer or a Breakout clone.

Bullet is a physics engine library usable for collision detection. It is used in some video games and movies.

PhysicsFS is a library to provide abstract access to various archives. It is intended for use in video games. For security, no file writing done through the PhysicsFS API can leave a defined write directory. For file reading, a search path with archives and directories is defined, and it becomes a single, transparent hierarchical file system. So archive files can be accessed in the same way as you access files directly on a disk, and it makes it easy to ship a new archive that will override a previous archive on a per-file basis.

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

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.

This package provides the standard library for Inform 6.

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.

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.

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.

Pygame is a set of Python modules designed for writing games. It adds functionality on top of the SDL library, allowing you to create games and multimedia programs in the Python language.

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.

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.).

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

pytmx is a map loader for python/pygame designed for games. It provides smart tile loading with a fast and efficient storage base.

MyGUI is a library for creating Graphical User Interfaces (GUIs) for games and 3D applications. The main goals of MyGUI are: speed, flexibility and ease of use.

LÖVE is a Lua framework for making 2D games. Nuklear is a minimal state immediate mode graphical user interface toolkit. This package is the Nuklear bindings for LÖVE created by Kevin Harrison.

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

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

Inform 6 is a programming language designed for interactive fiction. This version of the compiler has been modified slightly to work better when the Inform standard library is in a non-standard location.

This package provides an Anvil file format parser.
