A shape could only be moved and reshaped point by point. Whoever
wanted it larger or turned pulled every point alone, and for several
shapes or a group there was no way at all. The answers in the issue
settle the rest: the change is baked into the points, nothing of it
is remembered, and the line width stays.
- With Select the selection stands in a frame of eight squares and a
knob, drawn like the one of the scene view. It holds one shape,
several shapes or a group, the same selection that is dragged as
one.
- A corner square scales from the opposite corner, a square on an
edge in its own direction. Shift keeps the proportions, Alt scales
about the middle.
- The knob turns round the middle of the frame, with Shift in steps
of 15 degrees. After the pull the frame stands upright again.
- The inspector has a band TRANSFORM with X, Y, Width, Height and
Rotate by, and the buttons Flip horizontal and Flip vertical.
- Points, handles, gradients and texture tiles are taken through the
same matrix. The rule is a pure function in vectorTransform.ts,
transformShapesCommand makes one undo step of any number of
shapes.
- A press goes to a point or a handle first, then to the frame, then
to a line. shapeFrame.ts holds where the handles are and what a
pull of each means.
Decided here:
- The frame stands 15 pixels off the shapes. The points of a shape
lie on its bounds, so a square on the bounds would cover them.
- The knob only turns. In the scene view it scales as well.
- A side cannot be pulled through the opposite one, the frame keeps
at least 1 pixel.
- Coordinates are rounded to a thousandth of a pixel, so a quarter
turn is exact.
- A texture tile stays upright under a turn and grows to the bounds
of the turned tile. The bands of a gradient stay square to its
axis under an uneven scale.
- The switch Scale stroke of the proposal is not built.
Found on the way:
- The inspector of a shape is now taller than the window. Two checks
of module 47 no longer found their row or button on the screen and
use the new hook inspectorButton, which scrolls there first.
- Not solved: with a shape at the top edge of the view the knob lies
outside the tab. The wiki names it under the limits.
Taken over from #217: the e2e check for two selected shapes without
a group, and unit tests for the snap of the common offset and for
the gradients of the shapes dragged along.
Tests:
- Gate on melektaus-atx: 209 files, 3176 tests (3121 + 55), exit 0
- e2e 47,48 on melektaus-atx: 112 checks, all pass
- No full run and no smokes. The sum of 1664 (1660 + 4) is reckoned,
1660 is what CI counted for 6d79cf5.
- 55 unit tests: 25 in tests/core/vector-transform.test.ts and 30 in
tests/editor/shape-frame.test.ts
- Four e2e checks in block 47k of module 47: pull a corner, turn
with Shift, type width and rotation, drag two shapes without a
group
- 47 unit counter-probes and four browser counter-probes all fail
their tests. Four of the unit ones did not at first: two showed
dead code, which is gone, two got tests.
- Not checked in the browser: the edge squares, Alt, the cursors,
the flip buttons and the rows X, Y and Height

# 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, container, clip area, texture, vector art, pixel art, palette, animation,
|
||
curve, tile, tilemap, state machine, shader, 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.
|
||
|
||
```bash
|
||
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:
|
||
|
||
```bash
|
||
node tools/seed-e2e.mjs && node tools/e2e.mjs # the editor, 1664 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](https://git.nockal.com/meleki/game-maker/wiki/Development).
