Show where an inspector row can be dragged and answer the pointer
After #310 rows could be dragged by their mark, but nothing said which
marks take a drag, and the pointer on one changed nothing but the
cursor.

- A mark that drags is now a Grip: the same widget wrapped, the same
  size, so the value column stays where it was. Once sortBlocks takes
  it, it carries six faint dots at its left edge.
- Marks that cannot drag stay plain: the variables of a placed object
  and the fields of a typed struct show no dots.
- With the pointer on a grip its dots light up and the whole block that
  would move is washed in the accent colour, a struct with its fields.
  While the block is carried the wash gives way to the dimming, and the
  grip stays lit.
- While a block is carried the other grips let the pointer pass: no
  lit dots, no wash. Every grip of the column shows grabbing instead of
  grab until the drop.
- The wash first used controlHover like list rows. In the inspector it
  is darker than the panel and vanished next to the dark fields, so it
  became the accent at 15 percent, the colour of the drop line.
- __gm.inspectorMark also reports the dots: none, idle or lit.

Tests:
- Gate on melektaus-atx: 236 files, 3576 tests (+4 in
  block-drag.test.ts, one of them a drag passing over another grip).
- e2e 22: 40 checks (+1, sum 1740). 22f-iii reads idle dots, moves the
  mouse onto the mark and reads them lit.
- Two counter-checks bite: no wash on hover fails 1 test, grips never
  made grabbable fail 3. A third: hover ignoring the drag fails 1.
- Screenshots of a lit single row and a lit struct block looked at.

Game Maker

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, joint, container, clip area, texture, vector art, pixel art, palette, animation, curve, tile, tilemap, state machine, shader, shader function, 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, 1740 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 runners – 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.

Documentation

Page What it covers
Concepts Assets, scene objects, overrides, play mode, the camera, the console
Accounts Signing in and out, the accounts, who a project belongs to, what the check tools need
Scenes The edited scene, the start scene, and switching scenes from a graph
Scene editing Placing, z-order, hierarchy, the editor offset
Behaviors Node graphs: variables, the node set, structs and lists, loops, nesting, editing
Structs Struct assets: a named shape that struct variables, fields and Pack/Expand follow
Colliders Shapes (box, circle, capsule, polygon), collision events, blocking movement, one-way colliders and raycasts
Physics Rigidbodies, the collider material, gravity, the fixed step, joints
Textures Images, frames, nine-slice, the filter, upload limits
Vector art Pictures drawn from shapes: the pen, curves, gradients and texture fills, combining shapes
Pixel art Pictures painted pixel by pixel: the palette, the tools, layers and frames
Fonts Font assets, the picker, what a text falls back to
Sounds Sound assets and Play sound
Animations Animation assets and the Animation tab
Curves Easings drawn by hand, the Curve tab, using one on a key or a Lerp
Shaders Shader graphs that sprites, texts, particle fields and cameras wear, their node set, passes, shader functions
Particles Particle graphs: a particle as a function of its age
State machines The asset, named transitions, State branch, Set state and State transition
Containers Templates, instances, screens
Tiles The tile asset, plain tiles and the two autotile kinds, the pictures as animation steps, the Tile tab
Tilemaps The tilemap asset, painting in the scene view, layers, what it looks like in the game
Plugins Extending the editor: the plugin file, how it is loaded, switching one on and off, API v1
Keyboard Every shortcut
Architecture Stack, source layout, the rules that keep it organised
Development Commands, the e2e suite, the example games, CI
API The PHP JSON API and the project document
