2D game development library. Gosu provides simple and game-friendly interfaces to 2D graphics and text (accelerated by 3D hardware), sound samples and music as well as keyboard, mouse and gamepad/joystick input.

Shoes is the best little GUI toolkit for Ruby. This gem is currently a placeholder until we properly gemfiy Shoes.

Make cross-platform 2D applications in Ruby

Gioco is a easy to implement gamification gem based on plug and play concept. Doesn't matter if you already have a full and functional database, Gioco will smoothly integrate everything and provide all methods that you might need.

Clean and powerful library for game programming

Framework for building and distributing games using Gosu

Written to play with Ruby

A minimal 2D Game Library built on top of the Gosu gem.

Enhanced ruby bindings for the chipmunk game physics engine.

[Please consider migrating to opengl-bindings2 (https://rubygems.org/gems/opengl-bindings2)] Ruby bindings for OpenGL - 4.6, OpenGL ES - 3.2 and all extensions using Fiddle (For MRI >= 2.0.0). GLFW/GLUT/GLU bindings are also available.

Ruby bindings to SFML

Metro is a 2D Gaming framework built around gosu (game development library). Metro makes it easy to create games by enforcing common conceptual structures and conventions.

An OpenGL wrapper for Ruby. opengl contains bindings for OpenGL. Be sure to check out {GLU}[https://github.com/larskanis/glu] and {GLUT}[https://github.com/larskanis/glut] gems.

Fidgit is a GUI library built on Gosu/Chingu

OpenGL accelerated 2D game framework for Ruby. Builds on Gosu (Ruby/C++) which provides all the core functionality. Chingu adds simple yet powerful game states, prettier input handling, deployment safe asset-handling, a basic re-usable game object and stackable game logic.

This is a high-performance Ruby C-extension for the excellent GLFW3 library.

Gosu-Android is an implementation for Android devices of the multiplatform Gosu library.

LiteRGSS is a Game library that allows you to easly make Games with Ruby. LiteRGSS uses SFML to get Inputs and to display Graphics.

Nerd dice allows you to roll polyhedral dice and add bonuses as you would in a tabletop roleplaying game. You can choose to roll multiple dice and keep a specified number of dice such as rolling 4d6 and dropping the lowest for ability scores or rolling with advantage and disadvantage if those mechanics exist in your game.

Parsing OpenGL specs, so you don't have to. Supports up to version 4.6.

A CYOA game engine

Jemini is a game library designed to allow creation of reusable features. How many times has someone implemented the aiming on a first person shooter, or a minimap on a real time strategy? Jemini comes packaged with lots of behaviors out of the box, with the ability to easily author more. Jemini uses Phys2D and Slick for physics and graphics, with 3D on the roadmap.

A simple framework that aims to improve your Gosu experience.
