Fit measured the nodes alone: a group drawn around them was cut off, and a graph holding nothing but a comment framed the empty origin. It now frames both sorts together. The rubber band ignored boxes entirely. It catches them now, into the *same* selection as the nodes — `nodeIds` and `annotationIds` side by side — so one drag moves all of it, one Delete removes all of it, and one undo takes it back. A box counts only when the band holds all of it, where a node counts on touching: a group wraps the nodes it holds and therefore overlaps every band drawn over any of them, and since it drags those nodes along, catching it by accident would be felt at once. A node inside a selected group is moved once, not twice — `travellers()` collects everything one gesture carries and lets each thing appear in it a single time.

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, container, texture, animation, state machine) 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.
- 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, 862 checks (GM_STEPS=20 for one step)
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, 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.
