Structs and lists were capped at two fixed levels (list of structs, struct with a list field). Anything deeper was dropped silently on load, in node settings and when written to a variable. The cap came from an early design choice, not from a technical need, so it is lifted completely instead of adding a third fixed level. - One kind list NESTED_KINDS replaces ListItemKind and StructFieldKind. The flat special cases in listItems.ts are gone, every value goes through one recursive path. - A struct inside a struct is declared, like a top-level struct. Values coming in over an edge are brought into that shape. Struct items in lists still take their fields from the value. - New valuePath.ts addresses any nested spot by keys and indices. ListSlot.field is now ListSlot.path. - Field commands (add, rename, remove) take the path to the struct. They change declaration, own value and all overrides in one undo step, as before on the top level. - Inspector: "+ Field" offers Struct and List on every level. A nested struct is a header row with its own "+ Field", its fields are indented one step further. - List tab: a list item shows "n items" and opens one level deeper. The title shows the path, e.g. "Listy · nums · [3]". - Pack in Pack now writes a struct into a struct field instead of text. Objects are kept at any depth and stripped at every exit. - A list edit in a struct field without an existing object override now starts from the shown value instead of an empty struct. - Old projects load unchanged. Save, load and save again gives the same result. Tests: - ./check.sh: 172 files, 2498 tests, CHECK EXIT 0 - e2e 21 + 22: ALL PASSED, 90 checks (new 21d-iii, 22f-ii, 21d and 22f updated) - 20 new unit tests in nested-values.test.ts and nested-list-slot.test.ts, three tests that pinned the old cap turned around - 6 counter-probes, each fails 1 to 8 tests, originals restored and checked with cmp - Not covered: a nested struct inside a struct item in the list tab has no e2e click 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, 1416 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.
