/gedg/ - Game and Engine Dev General

Game and Engine Development General

The Game and Engine Development General, or /gedg/ is for the discussion of creating games and engines, including the many tools and libraries involved in dev. One large incentive for posting on /gedg/ is code blocks. On /g/, you can share code like so

[code] paste your code here [/code]

We have an IRC channel #/g/gedg on rizon!

Closed Source

The term "closed" also includes "pay to view" code.

• Havok: Physics engine, also has an AI module (pathfinding, navigation meshes, etc.).
• RPGMaker: Tool to easily make nipponese text and number simulators. But more likely you will use it to make a porn/fetish game. Allows for customization if you know Javascript.
• Unity: Widely known, uses C#.
• Unreal: AAA game engine, uses C++.

Open Source Games

Games where you can learn from the source code.

• Brogue: Roguelike game.
• Cataclysm: Dark Days Ahead: Ambitious turn-based post-apocalyptic survival game.
• Mindustry: TD/RTS factory management.
• OpenRCT2: Open source recreation of RollerCoaster Tycoon .
• Quake III Arena: FPS famous for popularizing an old bit hack trick.
• RuneLite: Popular Old School RuneScape client.
• SuperTuxKart: Racing game that is similar to Mario Kart.
• Tales of Maj'Eyal: A well-known roguelike game written in Lua and C.

Not Gratis (technically, but we all know how to use search engines)

Programming and Architecture

• Game Engine Architecture: Powerful and thicc.
• The C Programming Language: If you can't build your game in assembly, you may as well settle for this. A legendary tome that is easy to find online for free.

Math and Physics

• Game Physics Cookbook: Lots of tasty game recipes.
• Linear Algebra Done Right: For those that want to go further down the linear algebra rabbit hole. Requires an understanding of basic proofs and sets.
• No Bullshit Guide to Linear Algebra: Book well-liked by many for being intuitive. There is also a free extended preview for those who don't want to buy the book.
• Numerical Recipes in C: The Art of Scientific Computing: Numerical methods like inverting a matrix and solving differential equations.
