Project mention: So you want to compete with or replace open source | news.ycombinator.com | 2024-07-18
Title feels misleading - skip to the end:
> As for me, I still believe in open source, and even in the commercial potential of open source. It requires creativity and a clever business acumen to identify and exploit market opportunities within this collaborative framework. To win in open source you must embrace this collaboration and embrace the fact that you will share the commercial market for the software with other entities. If you’re up to that challenge, then let’s keep beating the open source drum together. If not, these new movements(source-available software) may be a home for you – but know that a lot of hard work still lies ahead of you in that path.
This article feels more like a critique of the new "source-available" trend in tech whereby existing OSS projects sell out and try to retroactively re-license themselves to be more closed-source friendly. I've been sort of aware of this phenomenon since there was a small upset when Muse Group bought Audacity, though it appears it is still GPL[1].

I built Twins of Caduceus (a snake-based game where you have to control two snakes simultaneously) entirely using Phaser 3. I've had mostly very good experiences with it as a batteries included framework (renderer, asset management, physics, input, etc.)
It's a shame that the map/level editor is a eternal subscription fee with no fallback license. That means you're relegated to either building your own map editor or using something like Tiled.

Hypersomnia
Multiplayer top-down shooter made from scratch in C++. Play in your Browser! https://hypersomnia.io Made in 🇵🇱
Project mention: Show HN: Esports shooter on the Web in C++. I rely on floating-point determinism | news.ycombinator.com | 2024-08-01GitHub: https://github.com/TeamHypersomnia/Hypersomnia
I wrote a multiplayer shooter in C++ without a game engine (~170k LoC). The entire simulation is fully deterministic across Windows, Linux, MacOS and the Web built via Emscripten, recently even aarch64. Compared to e.g. state snapshots, this is arguably the hardest networking strategy that's mainly used by RTS games to synchronize hundreds of units without bloating traffic.
The goal is to be the one free and open-source Esports game. Hypersomnia was recently played on a massive LAN tournament:

- The atlas packer I wrote for the game was reused in Assassin's Creed, Skydio and received 2 scientific references: https://github.com/TeamHypersomnia/rectpack2D
- There were significant challenges in making Box2D suitable for this, e.g. it comes without operator= so I had to implement complete cloning of the physical world for when I have to roll back the predicted world to reconcile it with the server state. Note it's not enough to just recreate the b2World from velocities and positions - you have to clone all contacts, generated trees, and all cached state so that the order of subsequent operations stays identical.
