COB timeline (ARMBRTHA.COB)
- 0.0–0.4 s — rest pose (Create:
hide flare— the flash is only visible when firing) - 0.4–6.4 s — AimPrimary: turret +30° at 5°/s, sleeve +10° at 2°/s (both at the same time)
- 6.9 s — FirePrimary: recoil 5 elmo (in 10 ms), muzzle flash 250 ms
- 7.15–8.82 s — barrel return at 3 elmo/s (the slow return is original timing)
- 9.3–15.3 s — AimPrimary(0,0): leisurely back to the rest pose
The original aiming speeds really are this slow (5°/s turret, 2°/s sleeve) — the gunner of a Big Bertha takes her time.
