Editing a vector drawing made Pixi warn "destroyed while still bound
to a shader", twice with every change, once it had begun. It began
where an object wears the drawing through a shader asset. Each
change draws the picture anew and destroyed the one before it, but
the mesh of that object keeps its picture bound until it syncs. The
issue also asks for the button "Add shape" to go: a shape without
points cannot be given any, the Pen draws a new one.
- GeneratedPictures takes two more callbacks. inUse says that a
picture cannot be freed yet, soon runs a retry once whoever asked
is done.
- A replaced picture that is still in use waits in a list of its
own. It is freed right after the redraw that asked, as a rule. On
a later ask where its wearer was not part of that redraw.
- TextureLibrary tells a bound picture by the listeners for change
on its source. Under WebGL the bind groups are the only ones that
listen there. The retry is a microtask.
- The rule is asked for every drawn picture alike, whoever wears it.
- The inspector of a drawing and of a shape has no "Add shape" any
more. "Delete shapes" for several selected shapes stays.
Decided here:
- Under the list of shapes a second note says "The Pen draws a new
shape." while only the asset is selected.
Found on the way:
- Reproduced on a throwaway copy of the project the report came
from: 6 warnings for 3 changes with the shader override on the
object, none without it. After the change none, and no replaced
picture is left waiting.
- The fixture project of the tests never showed the warning. No
object there wore a drawing through a shader.
Tests:
- Gate on melektaus-atx: 211 files, 3219 tests (3209 + 10), exit 0
- e2e 47,48 on melektaus-atx: 113 checks, all pass
- e2e 28,30,31,39,40,47,48: 350 checks, all pass, run before the
wording of the new note changed
- The first gate was red: an existing test read the wording of the
note that had changed. Only three test files had been run after
the change.
- No full run and no smokes. The sum of 1668 (1667 + 1) is reckoned,
1667 is what CI counted for ec2fd90.
- Ten unit tests, five of them against the real bind group of Pixi
in tests/viewport/bound-pictures.test.ts
- One e2e check in block 47b-ii of module 47: a drawing worn through
a shader, three changes, no warning. The check on "Add shape" now
reads that there is no such button.
- Nine unit counter-probes and two browser counter-probes all fail
their tests. Without the change the new check counts 6 warnings.
- Not checked: a tilemap or a particle emitter holding a picture
bound the same way. Nothing was looked at after the build, the
new note included.

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, 1668 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.
