Roderick Tron — terminal version

The second version, alongside web/ (browser). Runs on the magmacrunch.engine terminal backend.

A clockwork gentleman crossing the rooftops of an 1810s Dutch city: three hand-authored levels, a roll that carries further than a run, a chimney draught, a bell cannon and a coal trolley.

pip install magmacrunch-roderick-tron

It also appears in the arcade menu automatically — pip install magmacrunch brings it along with every other cabinet.

The screen

Sixty columns, which is the widest floor of any cabinet in the arcade and is not arbitrary: the browser's viewport is thirty tiles, a tile is drawn two cells wide so that it comes out square at a terminal's aspect, and thirty times two is sixty. Below that the camera would show less of the level than the browser does, and the levels were authored against what the browser shows — a gap you cannot see the far side of is a leap of faith rather than a jump.

Controls

Two verbs from the browser are missing, and both because a terminal reports key presses and never releases. There is no variable jump height, and the run is earned by travelling rather than selected with Shift. Neither costs any level its solution — tests/test_reachable.py searches all three with the smaller move set and agrees with the browser's own search, surface for surface.

Tests

pip install -e ".[dev]"
python -m pytest -q

Most of it needs nothing but pytest: tron/ imports no engine, and test_physics.py proves it in a subprocess. Two suites want node as well, and skip themselves without it — test_oracle.py runs the shipped browser modules in a vm and compares the port frame by frame, and test_reachable.py compares the two level searches. CI makes a skip fatal.

The level art in tron/levels.py is generated from web/js/levels.js by tools/gen_levels.py and checked in CI, so the two versions cannot drift.
