Details

A vector art asset is a picture now, which is stage 2 of #129 and the first stage that shows something in the browser: the asset sits in the picture picker, a sprite carries it in its Texture row and what the sprite shows has been rasterized from the shapes, the generator of #185 being registered for the type vectorart - installVectorArtPictures(app.renderer) hooks the source (core) and the generator (viewport) in once per page from App.ts, by a call and not by a module side effect, so a test may install it or leave it out; the rule lives in core and the painting in viewport - the new core/model/vectorPath.ts turns a shape into plain drawing commands (move/line/curve/close), closed rings being filled while all rings are stroked, a segment staying a line as long as neither of its ends carries a handle - a single handle is enough for a curve, the missing control point sitting on its own end, so a corner may stand next to a round side - and the way back to the first point is only drawn when it is curved, close doing it otherwise; holes go through one door only, Pixi recognising them from a GraphicsPath with checkForHoles, which tests containment rather than even-odd depth, which is enough for a ring inside a ring while without the flag the inner ring simply paints over the outer one (measured, see the counter-checks); the oversampling is the 2x from the plan - RenderTexture.create({resolution: 2}) puts 512 px on the GPU for a 256 canvas while texture.width stays the canvas size, which is the measure the sprite hangs on, and the render texture is the clip itself, so what juts out over the canvas is not in it and needs no mask; drawn pictures get the same sampler state as uploaded ones, setPictureFactory wrapping the factory for it, mirroring keep(); two measuring traps cost me runs - __gm.objectRect(id) gives the centre of the object and not its corner, so the first pass read four pixels next to the sprite and reported background while the rasterizer was correct, and the grid lines of the scene cross exactly in the centre point, so the hole check read #363940 and failed for the right reason, measuring beside it now; renderer.render() runs inside the picture request, which is safe here because every caller asks during its own widget redraw and the frame is drawn on the ticker afterwards, a nested render inside a running render pass would not be - that warning stands in the module head and in the notes; new module 47 with 8 own checks in its own lane (the picture on the GPU at double resolution measuring the canvas, the sprite showing the fill, the inner ring being a hole with the scene shining through, the later shape on top, the stroke running along the ring, a changed drawing getting a new key with the old one freed, and the sprite showing the new colour), the shapes being put into the model by mutate because the tab that draws them is stage 3, and 21 new unit tests in tests/core/vector-path.test.ts; three counter-checks hold: oversampling back to 1 fails the GPU check, checkForHoles off fails the hole check, and not drawing the curved way back fails a unit test; the full suite ran locally instead of only in CI because the change sits in TextureLibrary and touches every picture: ALL PASSED - 1165 checks, measured and carried into README and the wiki (#129 )

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, 1165 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.

Documentation

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
Colliders	Shapes (box, circle, capsule, polygon), collision events, blocking movement, one-way colliders and raycasts
Physics	Rigidbodies, the collider material, gravity, the fixed step
Textures	Images, frames, nine-slice, the filter, upload limits
Fonts	Font assets, the picker, what a text falls back to
Sounds	Sound assets and `Play sound`
Animations	Animation assets and the Animation tab
Shaders	Shader graphs a sprite wears, their node set, the properties they declare
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
