The wheel and the Fit button used to jump to the new view. Now the view takes a short way there, 200 ms by default, everywhere the editor zooms. The zoom steps stay the same, only the change is shown. - viewTween: tweenView is the way between two views as a pure function. The scale moves by equal ratios, and the world point that sits at the same place on screen in both views stays there. After a wheel step that is the point under the pointer. - ViewTween drives it on the ticker. A surface hands it reading, writing and drawing its own view and wraps its wheel and Fit code in change(). A step during a transition starts from where that one was heading, so quick steps add up to exactly as many steps. - Anything else that moves the view ends the transition. A pan jumps to the target first, and saving a view saves the target. - Wired into FreeViewport (Scene, Container, animation preview), SheetCanvas (Texture, Curve, Pixel art, Vector art), GraphCanvas, panAndZoom (Tile board, plugin node board) and the timeline. - Menu > General settings... sets the time in ms, 0 jumps at once. It is kept in this browser like the panel sizes, not in the project, and it is not an undo step. - A document that opens still comes up framed at once. The animation preview frames a new subject itself instead of calling fit(). - The pixel art readout names the step the view is heading for. Measured in the scene view at 200 ms on melektaus-atx, where every frame of the transition is a full redraw: - 500 sprites: redraw 6.7 ms, 16 frames, mean 18 ms - 1000 sprites: redraw 13.0 ms, 9 frames, mean 27 ms - 2000 sprites: redraw 32.2 ms, 5 frames, mean 58 ms Tests: - The harness sets 0 ms on every load, so the existing modules read the step and not the way. - e2e 46i samples one wheel step at 1000 ms a frame later: zoom 1.033 between 1 and 2, the point under the pointer kept at (134, -40). It lands on the view a 0 ms jump reaches. - e2e 46 and 49 expect the new menu entry. - Gate (atx): 234 files, 3563 tests, CHECK EXIT 0 (+15) - e2e 46,49 (atx): ALL PASSED, 43 checks (+3, sum 1735) - Three counter-checks fail view-tween.test.ts as expected. e2e 46i fails when the scene view does not carry its centre along.

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, 1735 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.
