A list of structs used to let every item carry its own fields. Adding an item meant typing the same fields again, and nothing kept the items in step with the struct asset from #253. A list can now name a struct type for its items, and the asset keeps them in shape. - A list variable and a list field get the row Items with Mixed, every struct asset and Make struct type. Make struct type collects every field any item has, so no item loses a field. - A typed item carries its type under the key `$struct` (ITEM_TYPE_KEY). listItems does not count it as a field. - A list that holds anything but structs refuses a type, also when the offending item sits in an override. The console names the list and the count, and the list stays as it was. - In a typed list `+ Item` adds an item with the defaults, without the kind menu. Field names are locked, values stay editable. - The rows of a typed item take their kind from the struct asset (declaredKind in InlineList.ts). An asset field shows the asset picker instead of a text field, as reported in the issue. - A struct item in a mixed list gets its own Type row. Switching a list back to Mixed keeps the type on each item. - syncStructTypes brings marked items into shape and carries renames into them, also inside overrides and nested lists. One undo step. - The delete dialog of a struct asset also counts typed lists. - The game never sees the key. World and sharedState strip it with withoutItemTypes and bagWithoutItemTypes, so a struct stays a plain object at runtime. - Add item and Set item get the setting Type. With a type they only accept a struct with exactly its field names (fitsType in SetItem.ts). Anything else is left out and logged. - The item indent from #252 is back to its old width, the narrow one squeezed the value fields. Not done: writing a variable does not check the type, and the List node offers no type. Found on the way: a test helper in list-of-structs.test.ts called nodes without params. It now passes the same arguments as the interpreter. Tests: - ./check.sh: 183 files, 2679 tests, CHECK EXIT 0 - e2e GM_STEPS=1,21,22,32,54,55: ALL PASSED, 150 checks - e2e GM_STEPS=1-6,21,22,32,54,55 before the follow-up: 404 checks - New: tests/core/typed-lists.test.ts, e2e module 55 with 13 checks - Counter-checks bite in unit and browser, originals restored by cmp Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Game Maker
A browser-based tool "one step before a game engine": create assets (scenes, cameras, sprites), place them into scenes, tweak their properties in an inspector and press Play – all in one program, all drawn inside a single WebGL canvas.
Live: https://nockal.com/game-maker/ · Widget playground: https://nockal.com/game-maker/?playground
The documentation is the wiki: https://git.nockal.com/meleki/game-maker/wiki – every concept, node, tab and shortcut, plus the architecture and the development workflow. This file is the short way in.
In one screen
- An asset is a named, typed thing (scene, camera, sprite, text, behavior, collider, rigidbody, container, texture, vector art, pixel art, palette, font, sound, animation, state machine, shader, particles, variables, tile, tilemap) with properties and no position.
- A scene object places an asset: position, sparse overrides of its properties, an optional parent. Only what differs from the asset is stored; the inspector paints it gold and offers ↺ / ↑.
- A container is a reusable group edited once and placed many times; its content is resolved from the template on every read. A screen is a container switched on and off.
- A behavior is logic as a node graph, placed like anything else and parented to the object it acts on. Play has no built-in behaviour – everything that happens is a graph.
- An account owns projects: the editor asks for a user name and a password first, and each account sees only its own projects. The Account menu at the far right of the toolbar changes the password and signs out.
- Play runs a throwaway copy of the project; every panel stays usable and Stop brings back exactly what was saved.
Quick start
Node 22 is required.
npm install
npm run dev # http://localhost:5175/game-maker/dist/ – API calls are proxied to production
npm run check # typecheck + lint + format:check + unit tests – the gate CI runs too
npm run build # writes dist/ and regenerates index.html; the folder is what nginx serves
The browser suite and the three example games need a machine with a GPU:
node tools/seed-e2e.mjs && node tools/e2e.mjs # the editor, 1513 checks (GM_STEPS=20 for one step)
# every tool signs in first – see the Accounts page
node tools/seed-jumprun.mjs && node tools/smoke-jumprun.mjs
node tools/seed-tetris.mjs && node tools/smoke-tetris.mjs
node tools/seed-actor.mjs && node tools/smoke-actor.mjs
Every push runs all of it on the Gitea runner – the gate as one job, build and suite as another beside it – so locally take the gate plus the step your change touches and leave the full run to CI. Details, the GPU requirement and the detached runner are in Development.
