The NetCode Guy

you’ve seen a hundred Opus 5 oneshot demos this week. here’s the first one you can play with your friends. because it wasn’t a oneshot. conversation is all you need.

@TAbrodi It's insane how much you can get done with Spawn in a few hours by just going with the flow.

@TheNetCodeGuy game looks so much fun you cooked

8 hours and 2,001 kills later

@calwoodford This is Overgrowth - You can play it here :D spawn.co/sleepy/overgro…

@TheNetCodeGuy which game is this??? 😮

Made with @spawn in around 8 hours. No artists. No code. Just describing what I wanted and giving feedback. spawn.co/sleepy/overgro…

@TAbrodi Now use L-Trees to have a beautiful blooming tree sim :)

i had a lot of fun building this terrain. my goal was to make a brutalist, snow covered procedural planet that feels great to inspect and fly through, while pushing optimization as hard as i could. - tsl node materials - procedural planet terrain - quadtree lod chunk streaming - worker generated chunks - `sharedarraybuffer` terrain pipeline - floating origin rendering - triplanar pbr splatting - ktx2 compressed terrain textures - exr sky lighting - gpu driven snow particles - inspect mode and fly mode

@boobs_scary Hey I did that 👀

Been watching this guy start with some super janky procedural noise and now he’s got a procedural everything. It’s insane.

@Strange_Heroes @Izkimar Keep your phone nearby <3

@TheNetCodeGuy @Izkimar Call me when the AI creates a polished experience. Btw I use AI too every day making software.

Damn WoW Classic+ hits different. Okay I'll try to refrain from trolling, but the state of AI game development is getting insane. And the craziest part is it's only just beginning. What you're seeing here is a project I started building in my spare time's spare time. A side project I spun up a little over a day ago and have been building in parallel to everything else. In that short window I was able to build a full zone inspired by Mulgore, the Tauren starting area in World of Warcraft. Target-based combat, fully functioning quests with rewards, XP, abilities, animations, multiplayer networking - a solid chunk of the starting building blocks you'd need for an MMO-style project. I didn't write a single line of code. But this isn't the typical "I made this in a single prompt" type of gimmick either. This was a real back and forth; letting the agent do its thing while layering in my own decisions too. All of the assets were AI generated, but I helped with the planning, curated and created the references, and after the agent produced the first pass of the level I came in and did a lot of manual level design for the village layout and general object placement. That push and pull between me and the agent is what actually makes this process feel much more like co-creation. All of this was built using @spawn, an AI gamedev platform for building web-based games. I genuinely think we're on the cusp of a web gaming revolution. It might not happen overnight, but as the quality keeps climbing people are going to catch on. At the end of 2024 I was struggling to build a simple Python auto-battler with Sonnet 3.5. Now I'm spinning up a fully networked MMO-style game in a matter of days. That gap alone tells you everything about where this is heading. Oh yeah I also forgot to mention, there's networked physics! "You can see this in action at the end of the video."

@Strange_Heroes @Izkimar Mirror lets you skip* netcode. Spawn lets you skip code entirely — say "make a game" and get one. Already networked with rollback, fully predicted, feels like you're offline. Mirror's rollback has been "experimental" for years. Can be done in Unity ≠ everyone can do it.

@Izkimar I think the devil’s in the details. I’ve been a Unity developer for 17 years full time. 🤷‍♂️

Most prediction/rollback implementations fail for a reason that isn’t determinism. It’s not reconciliation either. It’s something much more boring. And much more dangerous.

@SeloSlav @spawn Determinism is not a substitute for rollback. Network jitter means remote inputs arrive unpredictably. Rollback corrects these, not non-determinism. The only alternatives are lockstep or non-predicted server authority, where players feel network delay on every action.

It's crazy to think that this is multiplayer by default with networked physics. @spawn is killing it.
