ioq3

ioquake3 (and probably many other games) use Huffman Coding to optimize data transmission between the server and the clients. Huffman coding helps reduce the size of transmitted data, improving performance and lowering bandwidth usage. It is crucial for real-time multiplayer gaming. This is where I first came across Huffman Coding, as a kid (I was only 14 years old) at the time. I have fond memories developing mods for ioquake3 forks such as Tremulous and Urban Terror. Just to reiterate: the primary focus of Huffman coding is to minimize the total number of bits needed to represent a message. It is strictly for compression. If you want error correction, you should probably go for Hamming codes, Reed-Solomon codes, turbo codes, or CRC. That said, you can combine Huffman coding with those error correction codes. However, while not an error

Talking about Unlagged, I would kill for a clear explanation (with diagrams!) of various netcode improvements in it, CPMA and QL. I'm forced to try to piece together a mental model by finding crumbs on the web, with the current situation: https://github.com/minism/fps-netcode https://playmorepromode.com/guides/cpma-client-settings https://www.esreality.com/?a=post&id=2548041#pid2548771 https://old.reddit.com/r/QuakeChampions/comments/9jd3wv/for_... PS: the modern way of enjoying Q3 is https://github.com/ec-/Quake3e or CNQ3, these days. Don't know about https://github.com/ioquake/ioq3

I'm working right now on upstreaming WebRTC DataChannel support to Quake III[1]. Performance is great, but it was a huge pain to get working. WebRTC is insanely complex. It's also annoying that it can't be used from web workers or service workers. I hope someday WebTransport gets peer-to-peer support that is easier to use than WebRTC. And Safari support.

Thanks! This is loading just the demo assets, but I got the Emscripten support merged into upstream ioquake3 so you can check out the code, build it yourself, and with the right game asset files you can play the full game, Team Arena, mods, or whatever. https://github.com/ioquake/ioq3/pull/658 The only major feature missing from the original game is networking. Obviously kind of important for Quake 3. Should be possible with WebRTC DataChannel. And while the original game didn't have it, for the modern web a touchscreen control scheme is essential since half of everyone is on their phone. Of course it won't be great compared to mouse/keyboard but some mobile support is better than none. So those are the two features I'd like to add (besides performance optimizations; it's a bit slower than it should be for some reason).

The "canonical" open source version of Quake 3 (Arena?) is ioquake - https://github.com/ioquake/ioq3 / https://ioquake3.org. Last commit 18 hours ago.

I was bummed that there were no contributions in the 6 years this was open sourced, but it turns out that active development is actually happening in a fork: https://github.com/ioquake/ioq3
