A round of fixes to the Pattern and Song tabs: where a paste lands, what Shift does on a drag, how far the rows zoom, and how an item of a song is sized at its ends. - Shift does what Alt does on a drag: off the grid, on the tick. A Shift click on a note or an item still adds or unpicks it. A Shift press only decides on letting go: no drag toggles, a drag moves. - Ctrl+V lands under the pointer. The earliest copy goes on the grid line before it, the highest note on its row or the topmost item on its track, held to the keyboard or the tracks there are. Off the grid or left of bar 1 it lands at the start of playing as before. - The rows of the piano roll zoom to 64 px instead of 28, the tracks of a song to 320 px instead of 160. - Fit in the Pattern tab zooms the rows as well, so the notes fill the height, no longer held to the default of 14 px. - An item of a song can be pulled out by its left end past the start of what it plays, which then repeats. The offset goes round to the end of a round. A sound not loaded yet still stops at its start. - Both ends of an item snap to the start of a round of what it plays as well as to the grid, whichever is nearer. The end of a round between two ticks is cut to the tick before. A start put within half a tick of a round goes right on it, so it plays from the very beginning. - An offset past a whole round is not folded back to 0, so a pattern that grows later still plays from where the item said. - A middle-drag pans past the first and the last row, as it pans left of bar 1: the highest note or the first track up to half the height down, the other end up to half the height up. The room past them is dark in the piano roll and empty in the song. Tests: - Unit: song-edit 14, piano-roll 19, song 14 tests. New cases for the paste spot, pulling out left, the round snap and Fit. - e2e 64+65 on melektaus-atx: ALL PASSED - 54 checks (+4). New: Shift drag and Shift click, Ctrl+V under the pointer in both tabs, Fit zooming the rows, pulling a pattern out left and snapping a sound to the end of its second round. e2e 64 zooms the rows out again after Fit, so the keys it plays later are on screen. - Gate on melektaus-atx: 251 files, 3912 tests, CHECK EXIT 0. - Then the pan down the rows: e2e 64 on melektaus-atx ALL PASSED - 30 checks. Its pan check now also pans the top row down, half the grid's height, and a click above it draws nothing. Co-Authored-By: Claude Opus 5.5 <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, 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.
