Projects

A selection of things I have built. Each entry says what the problem was, what I did about it, and what it is built with — that is usually more useful to a reader than a screenshot.

1robie.github.io​

This site. A multi-instance Docusaurus site that hosts a portfolio, long-form guides and an API reference side by side, with local (Algolia-free) search and automated deploys to GitHub Pages.

MachineEngine​

Tech-mod machines on a vanilla server, with no client mod. A framework for Paper and Folia: machines that store, process and move energy, fluids and items, cables, multiblocks, upgrades and textured menus — on which addons and YAML packs build their content. Blocks and items are CraftEngine content sent in a resource pack; menus are zMenu inventories.

The interesting parts:

  • Transactional transfers. Every move of a resource runs in a nested transaction with snapshot and rollback, so nothing is lost or duplicated when one side refuses half-way.

  • Folia from day one. Transfers between machines in different regions are handed over asynchronously with escrow, instead of locking two threads.

  • One jar for Minecraft 1.20.6 to 26.3. Everything compiles against the newest Paper API, and a build check reads the bytecode to fail on any call that does not exist in 1.20.6; version-specific code lives in per-version modules loaded at startup.

  • Uninstalling never destroys data. Machines of a removed addon are kept as placeholders with their data, and come back with it.

  • Idle costs nothing. Machines sleep and are woken by what concerns them (an input arriving, an output freeing up), instead of ticking.

  • Stack: Java 21/25, Paper & Folia API, CraftEngine, zMenu, Gradle (paperweight userdev, convention plugins), JUnit headless test harness, GitHub Actions (CI, releases to GitHub, Hangar and a self-hosted Maven repository)

Mekanized​

Mekanism's machines on Paper, built on MachineEngine's public API only. Generators, ore processing, chemistry, logistics, multiblocks (reactors, turbine, induction matrix…), the MekaSuit and its modules, radiation and teleporters — with Mekanism's textures, recipes and names (MIT), and menus textured like Mekanism's windows using resource-pack glyphs in zMenu titles.

The interesting part: its content is data, not code. Blocks and items are CraftEngine templates and config factories (one row per tier), so a server owner tunes any machine, cable or item in YAML and /ce reload applies it to machines already placed. A snapshot test guards what CraftEngine makes of the content files.
