Float a document's tab in a window of its own, and dock it (#371)
The Parametric EQ has a tab of its own since #370, but Play is in the
sound FX's tab. A tab that can float keeps both in view. There is one
editor per kind, so the kind's pane is lent to the window and given
back on Dock, the way fullscreen moves the game view.

- A right-click on a document's tab opens a menu with Float and Close.
  `DocumentTab` passes the press to `TabStrip`'s new `onMenu`.
- `FloatWindow` sits on the overlay. Its title bar moves it, its lower
  right corner sizes it, Dock and the x close it. A press brings it to
  the front.
- `floating.ts` is the pure part: where a window opens, held whole on
  the screen, sized down to 320 x 200. Nothing of it is remembered.
- One window per kind. Another document of that kind opens there and
  closes the one it had. Its tab, if it had one, leaves the row.
- When the row showed the kind, it shows the nearest document whose
  kind is not in a window, else the scene (`neighbourOf`).
- Delete, Copy and Paste go to the window pressed last, and back to
  the tab showing after a press in the editor (`keyTab`).
- Previews tick and redraw for a kind in a window as for the tab
  showing. Fullscreen hides the windows. Loading a project or signing
  out closes them.
- Only documents float, Scene and Game stay in the row.
- Hooks: `floatWindows`, `floatDocument`, `keyTarget`.

Tests:
- Unit documents: 16 green, 5 new. Counter-check: `neighbourOf`
  without the window check turns its test red.
- e2e 44 (melektaus-atx, after steps 1-12 and 37): ALL PASSED,
  505 checks in the chain, 6 new for float, move, size, another
  texture, keys, Dock and x.
- Gate (melektaus-atx): CHECK EXIT 0, 274 files, 4236 tests.

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, 1744 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
