game-maker / suite (push) Successful in 7m26s

Details

The new node "Raycast all" answers with every collider along the ray instead of only the nearest one: it carries the same inputs and settings as Raycast (Ignore owner, Hit triggers, Layers from #158 ) plus "max hits" where 0 means all, and it hands back parallel lists sorted by distance - objects, colliders, points x/y, normals x/y, distances - next to count, so index i of every list speaks about the same hit; a collider counts once no matter how many convex parts its shape is built from, while a tilemap counts per cell it is hit in, and the filter sits in Solids.raycastAll like the one of #158 , the one path the editor run and Play both take, so all 12 new unit tests run through describe.each against both systems; the node needed the value system to learn something it could not do - a graph list carried numbers, text, booleans and bundles but no object handles, asList turned an object into its name, so objects/colliders would have been lists of names, which loses the object when two carry the same name, and collider children usually do; Value now knows a travelling list that may hold handles and "Item at" gives such an item out as an object, ready for Destroy, Apply force or Name of, while the single door into a stored file - writeTyped/asTypeOf - runs the list through the new storedList() so every object becomes its name again and nothing living reaches a project file, which is its own unit test over JSON.stringify; three list nodes follow the handles: "Index of" compares objects by identity because a name is not the object of that name, "Set item" and "Fill" write an object as an object, and "Join text" prints the names instead of the innards; this decision was mine to make because the question ran into the MCP timeout - the alternative was a list of names plus "Object by name", which is the smaller change but lossy; 4 new e2e checks in the new block 43e (shield and floor in one go reading 2 and "145, 280", the second object answering to its name, which only a real object in a list can do, "max hits" 1 stopping at the nearest, and the node showing the row) and 18 new unit tests, 12 in raycast.test.ts, 4 on the value system and 2 in the node catalog; two counter-checks hold: not counting tilemap cells one by one drops 2 unit tests, and answering with the nearest hit only drops module 43 with 2 FAILs; one finding on the way - the node read "maxHits" while every other input carries a spoken label, because int() took the key as its label, so it has a third parameter now, and the e2e check caught that, no unit test did (#157 )

Raw Blame History

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, 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, 1157 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.
