After the Chip, the Envelope, the Reverb and the one-knob devices, the Delay is drawn as a device of its own size too. Its screen shows what time, feedback, damping, wet and ping-pong make of a sound, and a light runs over the echoes at the beat they come at. - DelayPanel: a 680x280 plate in the Compressor's brushed aluminium, now exported as ALUMINIUM. A screen, levers for Sync and Ping-pong, knobs for Time, Feedback, Damping and Wet, and an Echo lamp. - The screen draws the sound as a white bar and each echo as a bar one step later. A bar is as tall as the echo is loud, evenly in dB to -60. It turns from warm white to rust as the damping takes the highs. With ping-pong the bars alternate above and below, the first left. - At most 24 bars are drawn, and the screen says how many more are heard. Under it stand the step and the end of the tail, above it where the highs of the first echo end. - The running light: DelayFace.tick returns true while the node is in the picture, so the editor keeps drawing, as for the Particles tab. The light goes round the span in real time, a bar glows as it is passed, and the lamp blinks with every echo but not with the sound. - On beats the screen counts at 120 BPM, as the tempo of the voice is not known in the graph. The time knob then names the note, dotted and triplet ones included. In seconds, 2 s and up reads "2 s max". - delayView holds the rules apart from the drawing: layout, tapers, echoTrain, echoCutoff for k rounds of the Butterworth low-pass, sweepAt and the texts. At wet 0 the rest is drawn faint. - delayEchoes in the core counts the echoes heard. The tail of a voice and the screen use it both. DELAY_ROWS, DELAY_SYNC and PING_PONG are exported. - Knob.reformat writes the number anew when its format changes, here when Sync switches between seconds and beats. - The test hook __gm.delay.panel returns knobs, levers, idle settings, the echoes drawn, the texts and where the light is. - Instrument presets give the Delay 4 columns. Echo Lead and Bell use one. In the picture of Echo Lead nothing overlaps. Found on the way: a node with a face draws no setting rows. The e2e check of a bypassed Delay (#354) read "Bypass: true" from them. It now checks the faded node and the stages heard, as before. Tests: - Unit delay-view: 17 tests, new. Counter-check: the first ping-pong echo on the right turns the side test red. - e2e 34 (melektaus-atx): 136 checks, 1 new. - Gate (melektaus-atx): 288 files, 4416 tests. - Pictures looked at: default, ping-pong, beats with damping, 83 echoes at 50 ms, wet 0, and the preset Echo Lead.

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, 1968 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.
