A set of tools for BYOND-based games

Game Developer

Hi, I'm Rob, a 34-year-old guy (he/him) living in Newcastle, WA who likes reverse-engineering, interpreters, and modding, and have worked professionally on popular game titles like Kerbal Space Program and From the Depths. I am currently working on ChilloutVR with Alpha Blend Interactive.

Here you can find some of my open-source projects, although I am slowly migrating to my gitlab account, since they support more features.

Current Projects

• BYONDTools @ GitLab.com - BYOND game engine source code analysis toolkit
• pyCSBinaryWriter @ GitLab.com - API for interacting with .NET-generated binary structures in Python
• BuildTools @ GitLab.com - My own shoddy toolbag, includes custom dependency-resolving buildchain inspired by Tup.

I also work on a bunch of other projects using alts.

Continued Learning

I am currently learning:

• Rust (computer language)
• Lark (lexing/parsing framework for Python)
• Crafting interpreters from scratch

This is to test that Notifico gets the hook.

BYOND2RGBA KeyError: 'rgb(X,X,X)' on attempting to render maps on /tg/station13 repo

Every time I try to render a map on /tg/station's repo it fails on z-level 1 with:

  File "C:\Python27\Scripts\dmmrender.py", line 90, in <module>

The RGB values differ per map but it happened for me on metastation, boxstation and a map I'm currently working on. This is using the latest version off of the python package index. (Installed with PIP)

Wiki link is broken

It looks like that wiki was shutdown.

Rendering on tg repo causes attribute error on map.

Attempting to render maps on tgstation's repo (and maybe others) results in:

AttributeError: Map instance has no attribute 'readMap'

Searching in the code, map.readMap is called in scripts/dmmrender.py and scripts/dmm.py but defined nowhere.
