The tab from #378 shows a Compressor as an editor. The user wanted it to look like a device as well, after a brushed aluminium plug-in, with a meter of the gain reduction instead of the pictures. The tab stays and is switched to per node. - Hardware look is a switch under Settings, on by default for new and existing Compressors. Only the editor reads it. - The panel is 820x280 px and opens straight in a window of that size. The window has no sizing corner and no Dock. A pane says so through `fixedSize`, and `keptSize` keeps the window's middle when it changes to that size. - A Compressor in this look never sits in the tab row. Opening one floats it, and switching the look on moves its tab into the window. - The panel has chrome knobs (threshold and makeup large), a meter with a needle that moves like a VU's, an LCD with the name and the reading, a lever with a lamp for auto-gain, and LEDs for the level going out. Everything is drawn in code. - The Knob takes a size and a chrome look, and leaves out its caption when it has no name, so the panel engraves its own. - `autoGainOn` is now `switchOn`, because the new switch reads the same way. - Where parts sit, the meter's scale, the needle's speed, the LEDs and the plate's grain are in `hardwareView.ts`, apart from the drawing. Decided myself: - The meter's scale runs by the square root, so the first dB is about as wide as the last nine. It is red from 10 dB on. - The LEDs light one every 3 dB from -39 to 0 dB and fall by 20 dB a second. - Switching the look changes the graph's fingerprint, like any other setting of a node. The sound FX is built again once. Findings, fixed on the way: - Pixi's `arc` goes on from the last point of the path. The meter's scale had a line from the corner of the face until each arc got a `moveTo` to its own start. - A text put into a Graphics makes Pixi warn that only Containers take children. The LCD is a Container now. - The first browser check read the needle at one moment and missed the short sound. The panel keeps the most its needle and LEDs showed. Tests: - Unit: hardware-view (10 new), documents (1 new) - e2e 34 (melektaus-atx): ALL PASSED, 122 checks (4 new). Played, the needle reached 20.9 dB and 5 LEDs lit. - Gate (melektaus-atx): CHECK EXIT 0, 283 files, 4355 tests (11 new) - Counter-checks: a window that keeps its corner instead of its middle, and a linear meter scale, each turn exactly their test red.

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, sound FX, instrument, pattern, song, bus, 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, 1953 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.
