The object queries only ever returned one object: Object by name, Child by name and Find all stop at the first hit. Getting every coin, every child or every item that passes a test needed a For each with its own bookkeeping. These nodes return the whole set as a list of Object, so For each and Find can use item straight away. - Objects by name returns every scene object with that name in scene order. - Children by name returns every match below object, nearer levels first, the same order as the singular node. - Children returns the direct children, with recursive all of them level by level. - Objects of asset returns every instance of an object asset or container by the same rule as Is asset, spawned ones included. - All four take a snapshot. Destroyed objects are never in it, disabled ones are, as with the singular nodes. - Find has a Mode setting: First, All, Any and Count. First is the default and hides the row, so existing graphs look the same. - Match follows the mode of its paired Find: done with items and indices, done with any, or done with count. An unpaired Match shows First, since the pairing only comes from the wiring. - First and Any stop at the first hit, All and Count walk the list. - Changing the mode drops edges at outputs the Match no longer has, in one undo step. SetNodeParamCommand now cleans the whole graph, but only edges that were valid before the change. - The palette entry "filter" adds a Find set to All with its Match. Found on the way: - After adding the filter entry, "find" + Enter picked Filter. The entry has node type Find, counted as an exact hit, and the tie went to the alphabet. The search now ranks by the entry id. e2e 6z-v caught it. Tests: - ./check.sh: 188 files, 2746 tests, CHECK EXIT 0. - find-modes.test.ts with 11 tests, 11 catalog cases for the four nodes, the asset input guard now expects 3. - e2e 6z-vii with 3 checks: filter from the palette, Count picked in the inspector drops the items edge, a run logs 2, 2, 2, 3, 4, "0, 2". - GM_STEPS=1-6: all passed, 278 checks. - Counter-checks fail as expected: every mode stopping early (2), Match ignoring the mode (6), cleanup on the own node only (1), no recursion (2), no inOrder (2), old ranking (1). In the browser a Match ignoring the mode fails both editor checks. 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, collider, rigidbody, container, texture, vector art, pixel art, palette, 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, 1535 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.
