A selected vector shape has its own inspector rows (#129)
Stage 4 of #129. Until now the inspector showed the rows of the asset
when a shape was selected, so there was no way to give a shape a colour,
an outline or a place in the drawing order without editing the project
file. The rows for a shape now sit where every other selection puts its
rows.

- SHAPES lists every shape of the asset, topmost row drawn last, the
  same way a layer list reads. Selecting the asset itself shows the same
  list below its own rows, with no shape selected.
- Each row paints its shape with the commands the rasterizer uses
  (shapeDrawing plus paintDrawing) into a 22 px swatch, the whole canvas
  scaled in, so the row also says where on the canvas the shape sits.
- The four order buttons from the issue (forward, to front, backward, to
  back) sit in two rows of two, and a row can be dragged to another
  place with a marker line. They are disabled when there is nothing to
  move.
- VECTOR SHAPE carries name, fill, opacity and an outline checkbox, the
  checkbox adding and removing the stroke instead of hiding it; line
  colour and width appear with it. A dragged colour slider is one undo
  step, the style rows going through previewingHandlers like every other
  row.
- A line width of 0 is no stroke, which the command rejects, so the row
  clamps at 0.1.

Findings:

- locate('Outline') aims beside the control, because it gives the centre
  of the label text and a wider label pushes a fixed offset out of the
  field. __gm.inspectorField(label) knows the centre of the control.
- A click into a text field sets the cursor and selects nothing, so a
  typed hex landed appended to the old one and parseHex returned null
  without anything failing - typeText only checks that the text is
  contained. A Ctrl+A goes first now.
- Four buttons side by side cut "Backward" to "Backw...", which only the
  screenshot showed. Two rows of two now, as in the tilemap panel.

Tests: ./check.sh 128 files, 1897 tests (was 127/1883). Full e2e suite
locally instead of only CI because the change sits in the inspector and
touches every selection: ALL PASSED - 1179 checks (was 1172), module 47
at 24 checks (was 17). Three counter-checks hold: not reversing the list
fails 1 unit test and 2 e2e checks, dropping the gap correction when
dropping a row fails 2 unit tests and the drag check, and a constant
signature kills module 47 because the outline rows never appear.

Refactoring round 5 covers the code since round 4 without changing behaviour: four identical copies of dot() and three of "nearest point on a segment" stood in the collision math, in the hit area of the collider outlines and in the polygon handles, so they moved into the new module src/core/util/vec.ts; the warning line, the busy state, info() and the caret reset were written out line by line in both the sign-in screen and the password dialog and are now FormStatus; the closing row "Cancel plus a confirming button, optionally one on the left" was built by hand in FormDialog, FilePicker, OpenProjectDialog and PasswordDialog and is now dialogButtons(); the header bar was drawn by the toolbar, the TabHeader and the Breadcrumb each on its own and is now drawHeaderBar(); AddColliderCommand and AddRigidbodyCommand share a base, each subclass only builds its own asset; Editor.ts derives the panes from assetEditors instead of repeating eight entries and clamps its splitters with clamp(); jscpd over src falls from 0.19 % to 0.14 %; dead code is gone - listScenes() has been orphaned since the Scene picker fell away (#183), DEFAULT_FILTER (#152) was never used, the two test hooks projectPickerRowAt/rowPosition and particleCompiles are read by no tool, and four functions lost an export they did not need; seven comments that told history ("used to", "no longer", "since #...") describe the state of things now, and that this changed nothing was proved by a rebuild - the bundle is md5 identical, b4ad0dfe... before and after; the README said Logout sits at the far right of the toolbar, which has been the Account menu since #182, and wiki/Architecture.md was missing src/core/util/ altogether; 4 new unit tests cover vec.ts, and switching the clamp on the segment off makes exactly one of them fail while none of the 76 neighbouring tests notice, so that clamping was covered nowhere before (#85)

Plugins belong to the project, and they load before it: the project file gained the field plugins: ["demo-plugin.js"] (default empty, no formatVersion bump), the Plugins tab's switch writes into it as an ordinary undo step (SetPluginActiveCommand) instead of into a server-wide plugins.json, and the start order is turned around - startPlugins only fetches the list of files, then editor.boot() runs and ProjectStore.load(id, prepare) hands the raw JSON through before it is deserialized, where pluginsOf(raw) reads the list and PluginManager.syncTo() activates exactly those; that is the point of the issue, because what a plugin registers has to stand there before normalizeGraph would throw it away as unknown (#126, #127), a project switch first stops what the new project does not name and then starts what it does, a file the server does not have is passed over silently, and after signing out the manager is dead so a late event cannot start anything in a torn-down session; on the server plugins.json, PluginStore::setActive, isActive, the route PUT ?r=plugins/{file} and the 403 for inactive modules are gone and GET ?r=plugins only answers {file,bytes,updatedAt}, which makes every plugin file fetchable - the consequence accepted in #117, written down in the wiki for #115 and #116; publishPlugins(root) only copies files now, the seeder switches the demo plugin on in the fixture project, and the Plugins tab carries a puzzle piece as its icon while only a plugin's own tab still goes without one (the knob and the socket are cubic curves, not arcs, which Pixi's parser draws as a spike after an L); 3 new e2e checks in module 38 and 5 new unit tests cover the project as the owner of the switch, its undo, the order, pluginsOf against crude input and an unknown file name (#119)

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, 1179 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.
