EnTT is a header-only library, containing (among other things)

• an entity component system based on sparse sets,

• a configuration system using the monostate pattern,

• a static reflection system,

• and a cooperative scheduler.

The Question is a short example visual novel showing that your Ren'py installation works, similar to a "Hello World" program in other programming languages.

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

Tsukundere is a game engine geared heavily towards the development of visual novels, written on top of Guile-SDL2. It is still experimental.

This package contains the shared libraries and Python modules of Ren'py. While functional, they are not meaningful on their own without the launcher and common Ren'py code provided by the renpy package and are only used to bootstrap it.

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.

TIC-80 is a fantasy computer for making, playing and sharing tiny games. There are built-in tools for development: code, sprites, maps, sound editors and the command line, which is enough to create a mini retro game.

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.

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.).

This repository contains CMake modules which are used across 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.

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

LÖVE is a framework for making 2D games in the Lua programming language.

dhewm3 is a source port of the original Doom 3 engine (not Doom 3: BFG Edition), also known as id Tech 4. Compared to the original version of the Doom 3 engine, dhewm3 has many bugfixes, supports EAX-like sound effects on all operating systems and hardware (via OpenAL Softs EFX support), has much better support for widescreen resolutions and has 64bit support.

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

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.

libccd is library for a collision detection between two convex shapes. libccd implements variation on Gilbert–Johnson–Keerthi algorithm plus Expand Polytope Algorithm (EPA) and also implements algorithm Minkowski Portal Refinement (MPR, a.k.a. XenoCollide) as described in Game Programming Gems 7.

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.

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.

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.

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.

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.

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.

Package sdl provides a Driver for making native graphical apps.
