Project mention: OSS Game Engines are increasing their stars on GitHub due to Unity's missteps | news.ycombinator.com | 2023-09-19
For anyone interested, LibGDX[1] is a very nice open-source game engine for Java. It is cross-platform (mobile, PC/mac, web). Very popular and well maintained, too.

Project mention: Rerun 0.9 – a framework for visualizing streams of multimodal data | news.ycombinator.com | 2023-10-05
The creator of Rerun (Emil Ernerfeldt) also created egui [1], an immediate GUI library for Rust. The library is similar to Dear ImGui but it is written in Rust and can be used for desktop and web apps (compiles to WASM and uses WebGL, demo [2]). Desktop apps can target OpenGL (does not display correct colors on macOS, does not work in VirtualBox on Windows) or WGPU (uses native APIs for each platform, works without any problems, but the binary is a big larger).

Project mention: The Future of Node.js in Virtual and Augmented Reality Development | dev.to | 2023-07-19
Traditionally, VR and AR development involved complex frameworks and languages, but Node.js brings a fresh approach to the table. Its familiarity with JavaScript allows developers to write code for VR and AR applications with ease. By utilizing libraries like A-Frame for VR and AR.js for AR, developers can create immersive experiences directly in the browser using Node.js. This seamless integration opens up opportunities for a wider range of developers to enter the VR and AR landscape.

Bullet
Bullet Physics SDK: real-time collision detection and multi-physics simulation for VR, games, visual effects, robotics, machine learning etc.
I suspect most C++ physics libraries like Box2D (https://github.com/erincatto/box2d) or Bullet3 (https://github.com/bulletphysics/bullet3) could really benefit a lot from SIMD.

To highlight this shift, we are introducing a new website which is now fully automated with Github. The paint is still fresh, but we hope to expand it with more information about the MonoGame Foundation, like how it operates, and how to join it or contribute.

A more sophisticated approach may be to use something like Tiled (https://www.mapeditor.org), but it typically takes a lot of code to to parse a Tiled map, so I wouldn’t start there. The exact needs of your game will dictate the approaches you use. Starting simple means you can make good, visible progress getting your game to work. And I’m sure that plenty of real games have shipped where the levels are just text files.

assimp
The official Open-Asset-Importer-Library Repository. Loads 40+ 3D-file-formats into one unified and clean data structure.
Project mention: The Asset-Importer-Lib Minor Release Version 5.3.0 is out | /r/GraphicsProgramming | 2023-09-26 -
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.

Project mention: Focus: A simple and fast text editor written in Jai | news.ycombinator.com | 2023-09-02
https://pastebin.com/VPypiitk This is a very small experiment i did to learn the metaprogramming features. its an ECS library using the same model as entt (https://github.com/skypjack/entt). In 200 lines or so it does the equivalent of a few thousand lines of template heavy Cpp while compiling instantly and generating good debug code.
Some walkthrough:
Line 8 declares a SparseSet type as a fairly typical template. its just a struct with arrays of type T inside. Next lines implement getters/setters for this data structure
Line 46 Base_Registry things get interesting. This is a struct that holds a bunch of SparseSet of different types, and providers getters/setters for them by type. It uses code generation to do this. The initial #insert at the start of the class injects codegen that creates structure members from the type list the struct gets on its declaration. Note also how type-lists are a native structure in the lang, no need for variadics.
Line 99 i decide to do variadic style tail templates anyway for fun. I implement a function that takes a typelist and returns the tail, and the struct is created through recursion as one would do in cpp. Getters and setters for the View struct are also implemented through recursion
Line 143 has the for expansion. This is how you overload the for loop functionality to create custom iterators.
The rest of the code is just some basic test code that runs the thing.

GameNetworkingSockets
Reliable & unreliable messages over UDP. Robust message fragmentation & reassembly. P2P networking / NAT traversal. Encryption.
Halo was mostly all about single player and early multiplayer/local multiplayer but their online netcode has sucked since Blood Gulch. Lots of games do networking horribly, I have been in gamedev making networking and I hate most of what people do. The ones that have a clean natting, based on enet style reliable UDP channels, RakNet style punch are better (RakNet was good until Facebook bought it). It has come a long way but also fallen back. Valve source netcode (on github) is probably the best and you can check it out here. They started with the best in Quake networking, then to Source.
