Slot symbol animation for Spine 4.2
A slot symbol is a small rig with a few short animations — an idle loop that keeps the reel alive, a pop when it lands and a win when it pays. Riggy builds them from your layered art and a sentence, and writes plain Spine 4.2 data your engine already plays.
How a symbol is made
Drop the layered PSD: every layer becomes a part, groups tagged [bone] become bones, and the shape of a part comes from its layer mask, not only from its alpha. Then say what should move — “idle breathing, a pop on land, a win with a flash” — and the model rigs and animates it with tools that measure the art rather than guess it.
If your spec already has exact curves, paste them: a Bezier quartet copied from Spine or from your own spec is taken as is, with absolute time and value, the way Spine 4.2 stores it.
A real rig
Symbol pages appear here as real symbols are rigged. Meanwhile, this is a rig Riggy built from layered art and one sentence, playing in the official Spine runtime. More examples.
Crate of dynamite
A crate of loose things — six sticks, a cord and two flames. The sticks breathe on staggered timings so the pile does not move as one block, and the flames flicker on periods of their own.
