Engine v5.1.10

July 4, 2026

A patch to Connection.

2D games got a big placement upgrade: backgrounds and distant scenery can now be glued to the camera, so they always fill the screen — no more backdrops drifting away from the view, floating set pieces, or stretched skies. Repeating strips tile seamlessly across the whole view, parallax layers slide at their own speeds, and everything holds up at any screen shape from tall phones to ultrawide.
Mid-ground scenery (trees, ruins, set dressing between the backdrop and the play area) now sits properly on the ground across its whole parallax drift instead of floating over dips or drowning in hills.
onSoundEnd fires again: scripts that sequence dialogue or music off a sound actually finishing (instead of guessing with timers) work in real games, not just single-thread test harnesses.
Building a place and walking players into it in the same script now works — and place-travel errors show up in your logs instead of vanishing.
On phones, selection handles are now sized for thumbs — big enough to grab, never covering the object — and brush/draw tools have a visible ✕ to exit.
Objects you attach to a parent in another place now go where the parent is, deleting a parent cleans up its attached objects everywhere, and Savi gets told when something can't be saved instead of it quietly breaking on the next load.
Fixed a bug where one broken sprite could permanently turn off automatic sprite sizing and pixel-accurate collision shapes for every other sprite in the room.
Spinning objects now tumble realistically instead of holding a fixed axis — long or flat objects thrown with spin will wobble and flip the way real ones do.
Your game has a music system now: api.music.play("cdn/music-….mp3", { fadeMs: 800 }) starts or crossfades the room's soundtrack, stop fades it out, duck dips it under dialogue, now() tells you what's playing and where it is. Layers let you stack stems ({ layer: "drums" }). Players joining mid-song hear the right spot, and editing your UI never restarts the music.
api.audio.duration(clip) gives you a clip's real length in seconds (null until it's known) — no more measuring rituals for timed sequences.
playSound finally honors bus: ("Voice", "UI", …) so the right volume slider governs each sound, plus priority: for lines that must not be culled.
Your game no longer creeps down to its worst-looking quality while you're actively building — loading hitches from edits don't count against your hardware anymore.
Games that swap through lots of big 3D models (previews, galleries, dress-up rooms) no longer slowly fill graphics memory until rendering dies.
Game controls and menus now stay clear of the iPhone notch and home bar.
Editing big games is way snappier: script-heavy worlds apply Savi's changes in a fraction of the time they used to (a 3,000-object world went from ~2 seconds to ~0.3 per edit), and the engine no longer quietly does every edit twice.
Saving game data just got a lot safer: the new api.updateStorage reads your data, applies your change, and writes it back without ever overwriting someone else's save that landed in between — if two things touch the same save at once (double-click purchases, two rooms, an autosave racing a reward), both changes survive instead of one silently erasing the other. Perfect for coins, inventories, and gacha-style rewards that must land exactly once.
Save and load can no longer falsely report an empty save when storage is briefly unreachable — instead of your save looking blank (and risking a fresh session overwriting your real progress), the game now sees an honest "storage isn't ready yet" error it can retry.
Worlds built by scripts that painted tons of individual voxels no longer freeze for many seconds when the room starts — and they stay snappy while you keep editing.
Turning terrain off (or switching terrain types) now actually takes — no more ghost settings from the old terrain sticking around, and when a script gets rolled back, you're told everything it would have changed.
Music patterns written in standard strudel vocabulary now either just work (.lpq, .distort, .duck) or tell Savi exactly which vibe verb to use — no more cryptic "is not a function" crashes in your soundtrack.
pbr: true now works on custom geometry: sculpted and scripted meshes that paint textures with ctx.albedo() get the same derived normal/roughness/metalness detail your textured boxes and terrain already enjoy — each textured face derives maps from its own texture, no extra authoring.
Editing big worlds got faster again: the engine now re-processes only the objects your edit actually touched — a one-object tweak in a 3,000-object world costs what it would in a 10-object world, and an edit that changes nothing is near-free.
Worlds with heavy build scripts stay responsive: when lots of timers come due at once, the work spreads across ticks instead of freezing the room in one long stall — and any script that runs slow gets named in your logs (with how long it took and how to split it up) instead of freezing the game anonymously.
Publishing from your phone works properly now: the cover screenshots Savi needs get taken on mobile too, and a game whose flythrough picture failed once will quietly retake it next time you visit instead of staying stuck.
Edits that fail to save no longer disappear silently: when an edit can't be saved, the game's logs say so and Savi gets told "N spec writes were rejected and did not save" — so "my changes keep disappearing after reload" becomes diagnosable in-session instead of a mystery. Edits to an object spawned an instant earlier now save.
