COB timeline (ARMCA.COB)
- 0.00–0.40 s — Cruise — build scripts are empty returns, the nano spray is an engine effect
- 0.40–1.35 s — RequestState: the wings SLIDE out — wing1 4.5 elmo back, wing2 5.85 elmo forward (948 ms)
- 1.35–2.50 s — Construction hold
- 2.50–3.45 s — Wings slide back in (948 ms)
The build/attack scripts themselves are empty returns — the wing morph in RequestState is the entire animation.
