Scrubbing a number in the inspector and dragging a colour stop of a gradient told the editor about every input. Pixi repeats each pointer move shortly after, so both gestures paid for two previews per move. The issue asked to measure first and to build only from 10 % per move. The measurement showed about 50 %. - previewingHandlers still writes the model on every input but requests the preview through a FramePreview of its own. The commit cancels a waiting preview first. - The preview handler of the GradientBar in shapeSection.ts does the same. - Wider than the issue describes: the row handlers also serve typing, the arrow keys and the colour picker. All of them preview once per frame now. Measured on stein2, fixture project with 120 extra objects, 120 moves 8 ms apart, three runs each: - Scrub: 236 project events before, 51 to 61 after. 45 to 50 ms per move before, 22 to 27 after. - Colour stop: 238 project events before, 50 to 51 after. 44 to 49 ms per move before, 22 after. - One preview still costs 13 to 17 ms. That price per frame is what remains. Finding, not fixed here: in the pixel art tab the palette colour and the opacity of a layer still preview on every input (PixelArtSide.ts), and so do the head fields of the curve tab. Neither was measured. Tests: - Gate: 198 files, 2907 tests (2903 + 4), exit 0 - e2e, full run: 1616 checks passed (1615 + 1), exit 0 - Smokes: 24 / 19 / 21, exit 0 - Four new unit tests in tests/editor/frame-preview.test.ts, two for a row and two for a colour stop - One new e2e check in module 02: a held scrub gave 10 project events in 12 frames, and the value is there before the release - Four unit counter-probes fail, 1 to 2 tests each. They ran on stein2, not in the container. - The browser counter-probe fails the new check with 50 events in 16 frames 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, container, clip area, texture, vector art, pixel art, palette, animation, curve, tile, tilemap, state machine, shader, 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, 1616 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.
