How does a Game Engine work? An Overview

• 2021-ext-studio-2

  1 6 1.8 Java

  

  A college course[1] I recently took involved working with LibGDX and Box2d to build a game from scratch. Rudimentary documentation,but the wiki[2] does a good job of breaking down how each component fits in.

• cute_headers

  5 4,094 7.0 C

  Collection of cross-platform one-file C/C++ libraries with no dependencies, primarily used for games

  The verdict for indie developers (not using Unity/Unreal) seems: just bite the bullet and buy FMOD (or Wwise or any of the popular proprietary audio engies).

  I was actually searching for a good open-source audio library to use, and found out that my options aren't that good. SoLoud is a pain in the ass to install and integrate into an existing codebase, and OpenAL doesn't have any good implementations available (either proprietary or LGPL). I'm now just using a simple single-header audio library in cute_headers (https://github.com/RandyGaul/cute_headers/blob/master/cute_s...), but will probably switch to MiniAudio once the high-level API is finished (https://github.com/mackron/miniaudio/issues/196)

• zig-pypi

  2 132 4.6 Python

  The Zig programming language, packaged for PyPI

  

  Did you consider the Zig toolchain? It's also a full C/C++ compiler toolchain (basically a packaged Clang), and comes with enough Windows headers (from the MingW project) to build games.

  For instance here is Zig as Python package to provide a simple cross-compilation solution for other Python packages that need to build native DLLs:

• bevy

  572 32,060 9.9 Rust

  A refreshingly simple data-driven game engine built in Rust

  

  The most exciting thing happening in game development is the move towards ECS (Entity Component Systems). Hopefully with games like Overwatch using it (and other big names), it'll see an uptick in usage.

  Unity is reworking their systems to use it by calling it "DOTS" (https://unity.com/dots), and this wouldn't be a HN post without mentioning rust so there is also bevy (https://bevyengine.org/) which is great.
