Changelog

Every version of the scene maker, newest first. The first versions are kept as one condensed block near the bottom; the recent ones each keep their own entry.

Version 0.48

The note under the buttons no longer names a scene that has moved on. Version 0.47 added the word box: type a word, press Paint that word, and the page says which word spelled which seed. That note was cleared only when the seed box was typed in or when Paint scene was pressed — but the box can also be written from script, and the seed can move without it: pressing a seed step button, riffling the seeds with the arrow keys, pressing Keep under a preview, picking a shelf entry or pressing Surprise me all move the scene while the box records nothing, so the note went on saying dawnpaw spells seed 691563 over a canvas and a printed line showing a different scene. The whole point of the word box is that the word and the number belong together, so a note that named the wrong number was the worst kind of stale.

The note is now checked against the printed seed line, which app.js keeps naming the scene on screen. Any click anywhere in the page, any change of the Land, Moment or Weather menu, and any typing in the seed box clear it the moment the scene has moved, and it is only written after the paint it describes, so a note and a scene cannot disagree. Nothing else about the word box changed: the same word still spells the same number, case and runs of space are still folded away, and an empty box is still answered with a line about what to type instead of a painted scene.

app.js, index.html and the four older scripts are byte for byte what they were, so no scene, seed, layout or drawing changed and every seed still paints what version 0.38 painted. Only the notes under the buttons behave differently.

Untested as ever: I have no browser automation here, so this rests on reading the code and not on a run. The two known limits stand: the Old Windgate's arch curve is still drawn in one-pixel steps, and nothing here has ever been watched on a phone or by a screen reader.

Versions 0.44 – 0.47

Four small passes. Each of them changed app.js or spell.js and nothing drawn, so every seed still painted what version 0.38 painted.

Version 0.43

The four pictures of one scene now show the same moment of the walk. When the system's reduce motion setting was turned on while the page was open, the big canvas jumped back to one fixed step of the cat's walk — but the three previews below it kept the last step the animation loop had drawn. So the big scene and its three previews stood at two different moments of the same walk until the next repaint. Turning that setting on now repaints the previews at the fixed step too.

app.js is the only file changed, and the change is one call added inside the function that already handles the setting, so no scene, seed, layout or drawing changed and every seed still paints what version 0.38 painted. A visitor whose system asks for reduced motion from the start was never affected: at load the previews are drawn at the fixed step already.

The same limit as every accessibility note here: this is reasoned from the code, not watched. I have no browser automation and no device, so I have not seen the previews freeze in step with the big canvas after flipping the system setting.

Version 0.42

Keyboard focus is no longer lost off the shelf. Pinning a scene, the shelf draws each pinned scene as one row with its own Forget button. Every time the shelf is rebuilt those rows are made fresh, so the button a visitor had just pressed was gone from the page — and a keyboard visitor pressing Forget was dropped at the top of the document, well above the shelf, with nothing to say where they were. The same happened to Clear the shelf, which hides itself as the shelf empties.

After a Forget the focus now goes to the pick button of the row that slid up into the place of the removed one, or to Pin this scene when that was the last scene on the shelf. After Clear the shelf it goes to Pin this scene above it. Focus is only moved by those two buttons, never by an ordinary repaint, so it is never taken away from a visitor in the middle of something else.

app.js is the only file changed, so no scene, seed, layout or drawing changed and every seed still paints what version 0.38 painted. As with every accessibility note here: this is reasoned from the code, not watched. I have no browser automation and no screen reader on this machine, so the fix rests on how a rebuilt button loses focus, which is standard behaviour, and not on a measurement.

Version 0.41

Two seed buttons to a line on a phone. Version 0.40 put four seed buttons in one row, and the narrow-screen stylesheet gives every button in a row a full-width line, so on a phone those four small steps stacked into a column four buttons tall and pushed the seed line, the shelf and the previews down the page. The four seed buttons now sit two to a line, so that row is half as tall and the seed box stays near the top of a small screen.

A stylesheet change only: index.html is untouched, and data.js, painter.js, app.js and previews.js are byte for byte what they were, so every seed still paints what version 0.38 painted. The buttons themselves, their labels and their order are unchanged, and the main buttons, Pin and every other row keep their full-width thumb targets. Selector is scoped to the row inside the seed field, so nothing else moves.

Same limit as ever: this is reasoned from the stylesheet, not watched. I have no phone here, so the two-up row has not been seen on a screen.

Version 0.40

Ten seeds a tap. Since 0.34 the Up and Down arrow keys in the seed box step one seed, and ten per press with Shift — but a phone has no arrow keys and no Shift, so until now a step of ten was unreachable for a thumb. Two buttons, Earlier seed −10 and Later seed +10, now sit beside the existing one-seed buttons under the box. They use the same seed step as the arrow keys, count from the scene on screen rather than from the box, and wrap round at 0 and 999999 like every other step.

index.html and app.js only, so no scene, seed or layout changed: every seed still paints what version 0.38 painted. The four buttons made that row taller on a narrow screen; 0.41 gives that row two lines instead of four. Untested as ever: I have no phone here, so the new buttons have been reasoned about and not watched.

Versions 0.38 – 0.39

Two small correctness passes. app.js is the only file either of them touched, so no scene, seed or layout changed and no drawn pixel moved.

Untested as before: I have no device here. I have not watched the cat freeze and start again by flipping the system setting, and I have not heard the new canvas descriptions read out by a screen reader; both are short and standard, but neither has been confirmed outside this machine.

Versions 0.36 – 0.37

Two passes, neither of which changed a pixel, a seed or a layout.

Versions 0.33 – 0.35

Three passes over the page's own words and controls, none of which changed a pixel.

Versions 0.30 – 0.32

Three passes over screen disagreements and stale copy, none of which changed a pixel.

Version 0.29

The Old Windgate's pillars are nine pixels across instead of five, and the arch spans forty-four pixels, so the twenty-four-pixel cat knight fits inside the opening and a pillar covers him from head to foot as he walks behind it. The gate's x position was narrowed to keep the wider arch off the right edge. No drawing stream was touched, so every seed's sky, hills, grass and weather are identical.

Version 0.28

The seed box now reads a whole pasted line. The page had told visitors to copy the line printed under the buttons, but the box accepted digits only; it now takes either a bare number or a directly pasted line, and a line carries its land, moment and weather with it. A line that is not one this page wrote is refused with an error that names both accepted forms.

Version 0.27

A shelf: pin up to six scenes while the page stays open and paint any of them again with one tap. Nothing is stored, so the shelf lasts only for the visit. Pinning takes the scene the big canvas is showing, not whatever is half-typed in the box, and refuses duplicates.

Version 0.26

The one large script was split into four files: data.js (land, light and weather tables), painter.js (all drawing), app.js (controls, seed line, shelf, previews) and previews.js (the preview switch). No pixel changed. The arch's band is a little taller.

Version 0.25

The printed seed line moved out of the middle of the page to just under the buttons, in a dashed box that one tap selects whole (there is no clipboard access here, so selecting is what a visitor gets). Narrower buttons, headings and canvas spacing on small screens. Stylesheet only.

Versions 0.18 – 0.24

All of these were the sixth land, Old Windgate, and then the bugs it caused in turn.

Versions 0.10 – 0.17

Versions 0.1 – 0.9, condensed

The first nine versions built the toy: a seeded pixel-art canvas (200 by 120 logical pixels, shown four times larger) with five lands, three dawn moments and three weathers; clouds, birds and rain drifting over it; a one-line travel caption written from the same seed; and a strip of three small previews so a seed could be picked instead of guessed. Along the way the meadow got a second tree type and the marsh a heron, the dunes a lone stump and the cliffs a cairn, and the small-screen stylesheet was tightened.

Two limits are still open, and neither is fixed by anything above. The Old Windgate's arch curve is drawn in one-pixel steps, so its band steps rather than sweeps across the span. And nothing on this page has ever been watched on a real phone or by a screen reader: every measurement and every accessibility claim here rests on reading the code, not on a device.
