Engine v5.0.13

June 12, 2026

A patch to For Real.

Boardwalks built down slopes with tight switchback corners now render coherently — no more railing bars shooting past hairpin turns or flickering planks on long straight runs.
Savi editing scripts while you play no longer makes the world's grass and decorations flash and hitch — the scatter only rebuilds when you actually change the decorations.
Calling an api method that doesn't exist — whether it was removed in an engine update (like api.patch, removed in 4.5.2) or never existed at all (like api.removeObject) — now tells you the real method to use instead of a bare "is not a function".
When a script calls an old removed API name, the error now tells you the new name to use instead of a bare "is not a function".
The breeze is back! Grass, flowers, and reeds with wind on them sway again — bases planted, tips swirling in the wind you authored.
Screenshots no longer hitch the game: when Savi peeks at your world, a thumbnail gets captured, or you snap a shot for chat, the frame used to stall for ~8 frames mid-gameplay. Captures are now visually identical and nearly free.
Platformer fix: characters now fall off platform edges cleanly instead of stuttering up and down at the lip. Walking down slopes and stairs still feels glued, exactly like before.
A spotlight given a too-big cone angle (like an angle in degrees) used to go completely invisible with no error. Now it lights up at its widest cone instead, and Savi gets a log telling her exactly how to convert the value to radians.
Games with rich terrain no longer gray-screen on GPUs with strict texture limits — the engine now simplifies terrain shading on those machines instead of failing to draw the world.
Placing objects on the room grid now works in every spawn shape the docs show: spawn({ properties: { feetPosition: { tile: [x, y] } } }) (with optional offset) lands on the tile like the 3d-rooms guide says, including inline children. Mistyped tile positions get precise messages instead of a generic rejection, and using a tile position in a world without rooms terrain tells you why the object landed at the origin.
Walking through translucent things — light shafts, ghosts, holograms, glass effects — no longer slices the screen with hard edges. They now dissolve gracefully as you get close, exactly like you'd expect.
