Great work on pcg-ts this is the kind of deterministic scene graph I've been develloping for eiffel.app. This feels like destiny.

Worth mentioning that at Epic, we’ve been experimenting and monitoring the development of AI production tools for several years. It feels like we’ve now hit an inflection point where they’re genuinely adding value for developers. So time to fully commit.
Replying to @MoralzzX
Developers who are getting value from AI should speak up. There's safety in numbers. MOST developers are doing it and loving it - and if they're not talking about it it's mostly out of fear for haters attacking them, their product, and their company.

The Eiffel Tower, deconstructed with @claudeai from Eiffel's original drawings. Rebuilt with PCG-TS, a procedural 3D library designed for AI agents. Generated from a graph and rendered in real time with @threejs. Live demo + GitHub 👇

The bottleneck in AI game development isn't the models anymore. It's my own creativity. AI has allowed me to approach genres that historically required a lot of prior knowledge and experience, and it teaches me along the way. E.g. I'm building a heavily physics-based game (excavator simulator) and a music experience. I learn in real time while pulling off work that used to take specialized teams months. The impossible is now within reach :-) All this makes it an insane time for juniors breaking in. You can rapidly build real experience without being encumbered by the knowledge of what used to be impossible. AI is so new and changing so fast that there’s no large body of entrenched experience to overcome. The way we prompt today is already very different from a year ago. What it takes is an open mind, curiosity, and grit! And a lot of the seasoned veterans I’m talking to are having the time of their lives. They can finally apply their experience to pure creative direction and let the AI execute. Wild time to be making games... and to be alive in general.

The games we've long wanted, which didn't exist because they'd cost several times more to make than they'd earn back, will soon become possible. As will the games developers wanted to build, but couldn't with the resources available. It'll be a new golden age of gaming.

We can now easily convert old console games and computer apps to javascript. Just ask Claude or Codex to disassemble and convert to Javascript whatever executable and rom you want.

Want to make a game with AI? Delete Unity. Delete Unreal. Delete Godot. They were never designed for AI to work with. Use Three.js instead. LLMs suck at heavy engine UIs, but they excel at writing WebGL -> playable browser link in 30 seconds. @threejs @webgl_webgpu

Introducing pcg-ts: real-time procedural content generation for TypeScript. Scatter points, sample surfaces, stream worlds around a moving camera — from seeded node graphs. WebGPU accelerated, three.js optional. Nine demos, live in the browser.

Grid levels cook around a viewpoint. Cells enter with hysteresis and evict by LRU, and cell content never depends on cook order. The galaxy demo generates every planetary system from its star's seed.

AI agents can write code many times faster than a human. What this means is that you, the programmer, have a large amount of time to use those agents to write unit tests, to write acceptance, tests, to write property tests, to torture test, to mutate test, to QA test, and to otherwise ensure that the code meets its functional and quality requirements. And even after spending all that time, you will still be many times more productive than a human programmer, and the result will be better.
