Can you build a Unity-like 3D web engine using AI? 🧠Creating "Threenity" on Three.js & making games with AI agents. 🤖Follow for devlogs

Unity+ @threejs = Threenity Engine
I thought: I love Unity's workflow, but I love vibe-coding in threejs even more. There was no Threejs engine that felt like Unity, so I built my own. 300$ on @claudeai, 20B tokens, 800+ hours, 366k lines of code. And finally, I'm making a game!

@AgentOrToy @threejs @claudeai AI works very well with this interface. I've already tested it on one game, so I'm not worried about it.

Threenity Engine: Game UI
Anyone who's made games with pure JavaScript and @threejs knows: creating a beautiful UI is very difficult.
Threenity makes it easier: 10 min chatGPT / gemini -> 15 min @claudeai / codex = modular UI that's easy to modify.

[Artem Semenov @semenov_artyom]

@arnputz @threejs @claudeai Of course, Threenity runs on ThreeJS. It's pure web technology. The engine simply helps you navigate your path.

[Artem Semenov @semenov_artyom]

@noisemakerjon @threejs @claudeai Yes, of courses

[Artem Semenov @semenov_artyom]

@threejs @claudeai I tried to make the UI in such a way that you could easily customize any UI you need.

[Artem Semenov @semenov_artyom]

@XAFODIAN @threejs @claudeai Okay, I saw it, that's why I decided the world needed another look.

@cinpas5 @threejs @claudeai It has nothing to do with Roblox; it's just an example game. I need to make a simple game to understand what else is needed. I'm planning to try making a game with high graphics.

[Artem Semenov @semenov_artyom]

@aiseomastery @threejs Thank you, I'll try!

[Artem Semenov @semenov_artyom]

Thank you all for the support 🙏 Now I really see that building Threenity Engine wasn't a waste of time.
The idea was simple: build the first truly AI-native #gamedev engine, one that uses the full power of @threejs
And it looks like it's actually working 🔥

[Artem Semenov @semenov_artyom]

@locusrifle @threejs I don't copy Unity; I'm inspired by the UI. I don't see the point in inventing something new if they've already come up with one. I'll never be able to compare to the hundreds of engineers who've worked on this for years.

[Artem Semenov @semenov_artyom]

@duke_nukem_7 @threejs WebGPU- yes, it's the core renderer (Three.js r184 + TSL). WASM - yes, under the hood (Rapier physics, KTX2 textures). WebXR - not yet, but doable: Three.js supports it, though WebGPU+WebXR is still immature, so it'd start on a WebGL2 fallback.

[Artem Semenov @semenov_artyom]

@MateuMercer @threejs Steam is easy. Android and iOS are easy.
But Xbox, PS4, and Nintendo won't work.
Perhaps some packer will appear in the future.

[Artem Semenov @semenov_artyom]

@IvanMurzak @threejs @claudeai Thanks! Yes, I've decided to open source it, but I have a lot of work to do before then. I didn't think it would be of interest, so I can't do it right away.

[Artem Semenov @semenov_artyom]

@1Dev_Mono @threejs @claudeai You can make any game, even one with more complex graphics. I'm just making this game for myself. I guess I'll need to make a game with better graphics for demonstration purposes.

[Artem Semenov @semenov_artyom]

@AkshayPL @iBrews @threejs @claudeai @BeardScript Why do I need proprietary software? If I made something more advanced and user-friendly

[Artem Semenov @semenov_artyom]

@andreintg In Threenity, I'll try to maintain modularity.
Basically, you don't have to do anything manually; your AI agent will do everything. Then you can just go back and edit it.
