A vector shape could only be filled and outlined with one flat colour. Shading, glows and patterned surfaces had to be faked with stacks of shapes. Every shape now has a paint type for its fill and its outline. - Fill type: solid colour, linear gradient, radial gradient or texture. Line type offers the same without texture. - Colour stops are edited on a bar in the inspector, as agreed in the issue. A click on the bar adds a stop in the colour the gradient already has there, so adding never changes the picture. At least two stops remain. - The new Paint tool in the tab shows two handles for the selected shape: axis start and end, centre and radius, or the corners of one texture tile. "Handles: Fill / Outline" picks which paint is edited. - Moving a whole shape moves its gradients and tile with it. Every gesture is one undo step. - A texture fill always tiles, because Pixi turns a non-repeating pattern into a repeating one anyway. When switched on, one tile covers the whole shape. - Only uploaded textures and frames can be a fill, never a drawing. A drawing filled with itself would rasterise itself mid-raster. - The fingerprint of a drawing includes the texture and frame a fill points to, so the picture redraws when the image is swapped. Findings: - graphics.destroy(true) also destroyed the textures of the fills. With a texture fill it deleted the tile slice and the next redraw crashed on reading 'scaleMode' of null. It is now destroy(). - The gradient cache destroyed old gradients itself, which gave 20 Pixi warnings "destroyed while still bound". They are now handed to Pixi's texture GC with autoGarbageCollect switched on. The console of module 47 is empty again, the last CI log had 0 of them. Tests: - ./check.sh: 135 files, 2011 tests, exit 0 (before 134 / 1986) - npm run build: exit 0 - GM_STEPS=47, freshly seeded: ALL PASSED, 54 checks (before 44), 0 console warnings - 25 new unit tests, 10 new e2e checks in block 47i - Four counter-checks bite, originals restored and verified with cmp - Check sum 1232 in README and wiki, calculated (1222 + 10) 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, 1232 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.
