The pen only pulled out the outgoing handle of a new point, because the opposite handle was mirrored only if it already existed. The first segment of every dragged point was therefore half a curve. Beyond that bug, a point had no way to say how its handles relate. - A vector point has an optional mode: straight, corner, smooth or symmetric. Missing means corner. The mode is not part of the fingerprint, because it changes no pixel, only the next drag. - Dragging a handle follows the mode. Corner leaves the other handle alone, smooth turns it along and keeps its length, symmetric mirrors it exactly. - The pen pulls out both handles mirrored and marks the point symmetric. A plain click still sets a point without handles. - The tab header has a "Point: ..." menu for the last clicked or set point. That point is drawn filled. Changing its type is one undo step. Text instead of four icons, because the UI kit has no tooltips. - Switching a point without handles to a curved type first grows handles along its neighbours. Smooth and symmetric line the handles up and keep the rough direction of the curve. - A point inserted on a curve is smooth. Symmetric neighbours become smooth, because the split shortens one of their handles. - Alt-click still toggles between straight and symmetric. Found on the way: the old Alt rounding took the point at the other end of an open line as a neighbour, so its handles came out skewed. Fixed and held by a unit test. Existing points with handles now count as corner. Before, every drag mirrored. No pixel changes, only the next drag behaves differently. Tests: - ./check.sh: 129 files, 1917 tests, exit 0 (before 1903) - GM_STEPS=47, freshly seeded: ALL PASSED, 39 checks (before 32) - Check sum 1195 in README and wiki is computed (1188 + 7), CI measures it - Counter-checks: pen without 'symmetric' fails 3 checks, no smooth branch fails 1 unit test and 1 e2e check Co-Authored-By: Claude Opus 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, collider, rigidbody, container, texture, font, sound, animation, state machine, shader, particles, variables, tile, tilemap) 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.
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, 1195 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.
