Upgrade notes: v3

Français · Type: reference · Audience: author · Context: created project · Status: ready · Applies from: 3.1.0

The notes of the 3.x line, kept unchanged: a game that embeds the engine (3.1), line ids (3.2), list lines (3.3), the stage (3.4), then the step from 3.x to 4.0. The section numbers are those of the former docs/en/UPGRADING.md, so a reference such as "§38" still finds its section (the 4.x notes are on 4.1, 4.2, 4.3 and 4.4).

Read them with today's names: web-scumm/content, npx web-scumm … and create-web-scumm are quest-n-click/content, npx quest-n-click … and create-quest-n-click since 4.2.5, and the old names no longer work since 4.3.0 (Coming from web-scumm). The whole upgrade procedure is Upgrade.

8. A game that embeds the engine (a copy of src/engine)

Your src/main.ts no longer copies the bootstrap: it calls bootGame (src/engine/boot.ts) and says only what is specific to your build:

import { bootGame } from '@engine/boot';
import { game, layouts, manifest, minigames, commands, locales } from '@game';

void bootGame({
  game, layouts, manifest, minigames, commands, locales, version: __ASSETS_VERSION__,
  dev: { enabled: (q) => import.meta.env.DEV && (q.has('dev') || q.has('edit')) },
  sw: { register: () => import('virtual:pwa-register') },   // or `sw: false` without vite-plugin-pwa
});

bootGame picks the language (?lang=, the player's saved choice, the browser), waits for the fonts, opens the verified IndexedDB store (its early errors reach the App once it exists; without IndexedDB the verified localStorage adapter takes over), builds the App, exposes window.__game for the e2e drivers, starts the dev tools when dev.enabled says so (dev.patch can replace the game, the layouts and the store first, as the Studio demo does), shows the title, and registers the service worker through the module you inject, with the update offered only after a verified save. The pieces are exported on their own (pickLanguage, waitFonts, openStore) when a game needs a different order.

What else your build keeps: vite.config.ts with server.host on 127.0.0.1 unless WEB_SCUMM_LAN=1, the layout writer and every /__studio route behind authorizeStudioRequest (tools/studio/security.ts), and VitePWA with registerType: 'prompt', injectRegister: false, skipWaiting: false (mandatory with the update prompt); package.json with the scripts of section 7 (tools/doctor.ts, tools/serve.ts, scripts/e2e-pwa.mjs); scripts/e2e/lib.mjs (E2E_BROWSER, --prod; a script that reads the human output of npm run solve keeps working); env.d.ts with /// <reference types="vite-plugin-pwa/client" />. The engine's game is a compiled clone (compileGame), frozen when schemaVersion is 3: a tool that mutated the object it passed to Engine must go through the engine's API.

9. Line ids (3.2): translations and voices that survive an insertion

Applies from 3.2.0

Every say, toast and guide can carry a stable id (house.open-door.l-just-a-door: its owner, then the start of its text). A translation table and a voice clip are then keyed by it: inserting, moving or deleting a line never shifts the others. npm run ids -- --lines --write --map gives the ids to the objects that lack them and renames the keys of locales/*.json (a second pass renames from the current paths, nothing already recorded in ids.migration.json / ids.paths.json is lost); --lines=all first turns every plain string line into { say: ['hero', text], id }: required for a game that ships a language other than its own (game.lang, default en) or has voices; the sample game did it in 3.2.1. audio.voices[<line id>] plays without writing voice on the line. npm run validate -- --release reports a line without an id (an error, plain strings included, in a translated or voiced game: run --lines=all once; a warning otherwise); npm run i18n -- voices lists the lines with an id and no clip, and the clips no line claims.

10. List lines (3.3): looks, hints, fallback answers and reactions by kind

Applies from 3.3.0

The lines the engine draws from a list (a look list, a hint's lines, rules.fallbacks.<verb>) can be { id, text } instead of a plain string, a hint can carry an id, and so can a reaction by kind (rules.kinds[i]). Their translations are then keyed by the id (room:house/look.pantry.<id>, room:house/hints.<hint id>.lines.<id>, item:key/look.<id>, rules/fallbacks.look.<id>, rules/kinds.<id>.say), and audio.voices[<id>] voices them. npm run ids -- --lines=all --write --map converts the plain strings of lists in rooms/*.ts, items.ts, rules.ts and game.ts, names hints and kinds, and renames the keys of locales/*.json (--lines alone only adds ids to the objects that have none). A single look line (look: { door: '…' }) is keyed by its owner already and stays a string. A translated or voiced release requires them, like say lines (validate -- --release). The Studio edits a { id, text } line at the same path as a plain one (look.pantry[1]). The sample game: 109 ids, 91 translation keys renamed per language, French still 400/400.

11. The stage (3.4): nothing to rewrite

Applies from 3.4.0

A room's decor is its backdrop layer and its layout's walk is the walk zone main (stageOf, src/engine/core/ stage.ts): an old room keeps its picture (npm run e2e:visual) and its saves (a stage adds nothing to the state). Layers, occluders, lights, particles, several walk zones and their links are added when a room needs them (CONTENT_GUIDE "The stage"). A layout with both walk and walkZones keeps the zones (validate warns).

10. From 3.x to 4.0

Applies from 4.0.0

4.0 changes no format: the authoring schema stays 3, the save envelope stays schema 3, and every 3.x save loads. What changes is what is promised (Stability and support):

  1. Import from the public API. web-scumm/content (defineGame, defineRoom, every content type), web-scumm/player (bootGame, AssetManifest), web-scumm/minigames (Minigame), web-scumm/testing (Engine, solve, parseSave…). The @engine/* paths keep working but are internal. In a game of this repository: sed -i.bak -E "s#'@engine/core/(types|define|custom)'#'web-scumm/content'#" games/<id>/*.ts games/<id>/rooms/*.ts, then the others by hand (Public API says which name is in which entry).
  2. A game in its own project (Package reference): npx create-web-scumm, move games/<id>/* into game/, npm install, npx web-scumm verify.
  3. RevealDef is deprecated: use EndingDef (removed in 5.0).
  4. npx web-scumm migrate --check (or npm run migrate -- --check here) says whether anything is due.
