TheoTown Style Minecraft City Generator

TheoTown-style procedural city generation for Minecraft Java

What it does

Algorithmic Minecraft city generation from handcrafted roads and buildings. The system builds a seeded two-level street network, detects parcels from the resulting road cells, places major structures on primary frontage, fills remaining lots with smaller buildings, and uses filler assets to finish empty space.

Turn a handful of your own Minecraft builds into an entire city. Outline roads and buildings with marker blocks, and CityGen generates a seeded street network, parcels the lots, stacks towers to vary the skyline, and gives you a paste-ready result. Windows installer included. - chengmarc/minecraft-citygen

Build a TheoTown style Minecraft city from your own roads and buildings in minutes. This project turns a small handcrafted asset set into a complete city layout, preview, and paste-ready in-game result. It is designed for creators who want large-scale city generation without giving up the look and feel of their own Minecraft builds. CityGen builds cities from structures you mark up inside your own Minecraft world, using a handful of marker blocks. Roads, buildings, and fillers all follow the same convention: Marker blocks and signs are stripped from the exported result automatically — they never show up in your finished city. Type 1 — a single building. One gold/diamond pair marks the whole…from github.com

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
