[Calisthenics]

This is not how you write an anti-cheat. Animation indexes 958 and 959 are the parachute animation you want to check about, the rest are unneeded. You never check if player has a parachute which will also give false warnings for those who skydive.

FALL_FALL and FALL_GLIDE are animations that are not only used when airbreak. The best way to detect airbreak is velocity + speed + animation being equal to 1231 or 1196.
