The asset panel only listed the categories and types that hold assets. To make the first asset of a kind you had to know its category in the `+` menu. A switch now lists all of them, and a right-click on a heading offers just what sits under it. - General settings has "Show empty asset categories and types", off by default and kept in this browser. Applying it refreshes the panel at once through a new `onGeneralSettings` listener. - `groupAssets(assets, empty)` gives every category and type when asked. The empty ones stand faint with a count of 0, and an empty type has no chevron, since there is nothing to unfold. - `ListItem.faint` draws a row's label, hint and icons at half opacity, like a disabled widget. - A right-click on a category heading offers the types of that category without a submenu, on a type heading only that type. The empty space below the rows still opens the whole `+` menu. `ListView.onListMenu` passes the heading's id for this. - Every menu of new assets says "Create asset" above its entries, so a click on a type reads as making one. `MenuOptions.title` draws that muted line. It is not an entry and matches no search. Tests: - Unit asset-groups and view-tween: 23 green, 2 new. Counter-test with the empty flag ignored: the new groups test fails. - e2e 04 (melektaus-atx): ALL PASSED, 67 checks, 4 new and 1 rewritten. Counter-test with the heading id dropped: the 3 menu checks fail. The title is checked on the `+` button and on a type heading (2 checks extended), the rerun passed with 67 checks. - Gate (melektaus-atx): CHECK EXIT 0, 272 files, 4212 tests. It ran before the menu title. Afterwards only the menu and asset-groups units, typecheck and lint ran, all clean. 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, variables, struct, collider, rigidbody, joint, container, clip area, texture, vector art, pixel art, palette, animation, curve, tile, tilemap, state machine, shader, shader function, font, sound, particles) 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. Release… shares a link that plays the saved game on its own, without the editor and without signing in.
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, 1744 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 runners – 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.

| Sounds | Sound assets and Play sound |
| Animations | Animation assets and the Animation tab |
| Curves | Easings drawn by hand, the Curve tab, using one on a key or a Lerp |
| Shaders | Shader graphs that sprites, texts, particle fields and cameras wear, their node set, passes, shader functions |

| State machines | The asset, named transitions, State branch, Set state and State transition |
| Containers | Templates, instances, screens |
| Tiles | The tile asset, plain tiles and the two autotile kinds, the pictures as animation steps, the Tile tab |
