How it works
Placing a 1×1 object on a cell edge in an engine that only has whole cells. The full technical description of SubCell Placement — what it does, what it is made of, and what state it is in.
The premise
A specification for a RimWorld mod that lets a 1×1 item sit centred on a cell edge or on a grid crossing, instead of being forced onto a single whole cell.
The engine only lets a thing occupy whole cells and exposes no half-cell placement workflow. The document works out two ways to get the result anyway — one that works with the engine and one that fights it — and breaks each into small, testable phases.
What is included
Two independent approaches analysed against the engine's actual constraints
Phased implementation plan with testable acceptance criteria per phase
How it is built
SubCell Placement is built on C#, Harmony and Specification.
It is maintained in a private repository; its history is not published.
The method behind it
Every project here starts as a written specification, and the specification stays authoritative once code exists. The repository keeps a build plan with live status, an append-only decision log recording where the implementation departed from the plan, and a handoff document describing the true current state — including the parts that are not finished.
That is why a portfolio this wide is not a shallow one, and it is why this page can describe the product without overstating it.
Current state
Specified. Designed in full, build not started.
The source is private. What this page claims is checkable against the product itself, not the repository.
