Deliverable #10 · 2026-08-17

The ground has types — 64 kinds of ground, a river through the Village, and mountains in the Badlands

epic: ground-types delivered due with ground-types/008

Promised 2026-08-17, the day Kris’s ground-types spec landed and the epic was planned. Until now the floor of every Area has been one flat green plane. This deliverable is the world getting ground under it: each cell is a hexagram, the lower trigram says what the ground is, the upper one gives it a flavour, and the game draws it.

Acceptance criteria

The live game (/play and the Android build) shows the Village of Lor with grass in several flavours and a river of Water running through the middle, and the Badlands with every one of the eight ground types on show in patches — including a mountain cluster with a taller peak, a volcano, and a pool of lava.
Water and lava sit visibly lower than the ground around them, and a character walking onto them sinks part-way in.
Where two ground types meet, the picture blends from one to the other — no hard block edges, corners included — while each cell is still exactly one type.
Mountains and deep water cannot be walked into; water and lava can (creatures have no nature yet).
Every player’s home has its own scatter of grass flavours.
The area map editor, opened from the world editor, paints any Area’s ground and saves it as a reviewable file that load-world applies — the same three-step path as the world map.

Delivered

2026-08-17, the same day it was promised — planned in the morning, built and live by night, in eight tasks (epics/ground-types/).

Play it: https://lor.kris.ai-task-runner.com/play — the web build at b8dbdb1, on the live server. Start in your home (grass in a scatter of flavours), walk out of the front door into the Village of Lor and cross the river; the Badlands, two doors on, has every ground type in patches, a mountain range with a peak core and a volcano at its centre, a lava pool, a deep-water lake, sand, snow, and stone floors around its doors.
On the phone: https://lor-server.cocreations.com.au/download/land-of-lor-v10.apk — the same build, signed. (Older builds now say “update needed”: the protocol moved to 4 because a client that can’t see a mountain would walk into an invisible wall.)
The ground itself, as files: land-of-lor/game/content/areas/<slug>.ground.json — one hexagram number per cell, a row per line, applied by load-world like the world map; written by npm run paint-ground and edited in the new area editor (Edit the ground → in the world editor).
How it was built and checked: land-of-lor/docs/handoff/ground-types.md, with screenshots beside it (handoff/ground-types/).

Against the acceptance criteria

Village grass flavours + river; Badlands patches with a peak-cored range, a volcano and a lava pool — yes, live: npm run verify-ground (15/15 against the droplet) reads the ground a real client receives in the Village and, walking through two doors, the Badlands, and finds the river, all eight types and the volcano.
Water and lava sit lower and a character sinks part-way in — yes, on the mesh rules (ground_mesh.gd, tested) and in the shots (badlands-wade-textured.png).
Blends between types, corners included, each cell still one type — yes: stage 1 by vertex colours, stage 2 by the four-cell shader; the cells on the wire are single hexagrams.
Mountains and deep water cannot be walked into; water and lava can — yes, one shared is_walkable on server and client, covered by the director’s tests (a step into a mountain is BLOCKED, into water lands); the live Badlands carries the impassable cells.
Every player’s home has its own scatter — yes, live (the verifier’s own home; the migration painted 18 Areas on the droplet).
The area editor paints any Area’s ground and saves a reviewable file — yes, driven end to end in headless Chrome (handoff/ground-types/area-editor.png).

Not yet seen by a human on a phone: the v10 APK is up, the renderer override is in, the same build passed on the web — but the on-device look and frame time on the Badlands are Kris’s to check.
