• flecs

  48 5,550 9.6 C

  A fast entity component system (ECS) for C & C++

Project mention: ECS, Finally | news.ycombinator.com | 2023-12-30

I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)

I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.

I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.

  zig game engine & graphics toolkit

  

Project mention: Zig Software Foundation 2024 Financial Report and Fundraiser | news.ycombinator.com | 2024-01-18

Myself and many others are betting on Zig in major ways, I truly think it has a bright future ahead.

In spare time, myself and a few others are working on a game engine in Zig[0], and the Zig core team has been very receptive to addressing issues our project faces and supporting us.

Others are working on pixel art editors[1], open source 2D RPG games[2], there's a group of independent folks working on a 3D massive immersive sim game[3], a group working on making Zig an amazing language for micro-controllers[4], etc.

Please consider donating $5-10 a month to the ZSF! They are a great group of people, and it has so many knock-on effects for others in the FOSS community. :)

I wonder if Godex[0] could be a fit for you. ECS based Godot, based on 3.x which has much more broad WebGL support.

That's cool, I didn't realize you had implemented an ECS library for tcod. At first glance it seems a bit more featureful than esper. The tags and relations functionality seem particularly useful for queries. l'll consider using it for the tutorial.
