# Float (SEQ 12-17)

Source: `TYPE1.SEQ`, read by `tests/helpers/fft-type1.js` into `tests/fixtures/type1.json`. Frames and delays are the binary's. Names are this repository's (`documentation/seq_animation_to_frame/AGENTS.md` "Names").

Notation: `F{n}({d})` = SHP frame index `n` displayed for `d` 60ths-of-a-second. `->` separates sequential frames. Duration = total time in milliseconds.

---

8-frame sequences that repeat the same single frame (70 or 71) with walk timing while the whole unit hovers. Between draws the SEQ issues MoveUp1 (`ffcc`), MoveUp1, MoveDown1 (`ffd0`), MoveDown1 and loops (`ffd5` IncrementLoop), so the unit rises 0 / -1 / -2 / -1 px and returns — the feet leave the ground line; the motion comes from the move opcodes, not from the frame data (`FLOAT_MOVES` in `constants/sprites/assembly.js`). In the raw TYPE1.SEQ pointer table these are animations 0x12-0x17 (the filtered index used here skips the six empty pointers 0x0C-0x11), with normal / Haste / Slow variants exactly like Walk (0x06-0x0B). A looping, speed-tiered stand-in-place bob is the idle of a floating unit (Float status); the game's ordinary stand idle (SEQ 1-5) is a single held frame. The animation name is inferred from this structure.

## Frame Tile Mapping

- F70 = `LF3` -> `BF3` -> `RF3` (same as walk neutral F11)
- F71 = `LB3` -> `BB3` -> `RB3` (same as walk neutral F16)
