Claude Code can now build things in a simulated physical world!🤖🏙️ With SimWorld, coding agents can construct buildings, plan cities, or even create video games inside a realistic simulation on Unreal Engine. Just write a prompt, your agent will call tools, retrieve assets, plan scenes, and test physics autonomously.... show more

Unreal + AI agents = humanity's playground upgrade. We fumbled Legos as kids, now prompts birth empires. Skynet starts with city planners, right?

Kudos to @haoqik322 @jamesflemingcs for the awesome demo, together with @Lingjun_Mao @koe_ye40329 for leading SimWorld coding agent platform! 🔥Checkout

Incredible demo — Claude Code autonomously building an inverted NYC in SimWorld via UE commands is a perfect showcase of agentic coding in physical simulations. The tool-calling, asset retrieval, and physics testing flow is seamless. Can't wait for the demo platform to try it myself!

this is insane!!!!

Hey there, city planner turned code wizard!

Is this using a unreal mpc

Yes

What program you build this with? I want to indulge support but i more wonder about the access to it and whether it needs to be outdone.

Awesome! It's open-sourced! Checkout codebase here:

this is amazing yes. the python layer you have going on. yes obviously a yes. yet. if you can strip out the python and make it more single file contained.. (which can be done with a bit of time and effort) you can flip the game on its head. i love, rate and support this.

This gets real when you publish task success rate across long tool chains, not just demo clips. Are you tracking failure causes by step type yet?

Building towards that and will open source soon!

Do you have this working for Unity as well?

not yet. It's on Unreal now

Any plans to port it over to Unity? Looks amazing
