As with all airborne actions, a variety of "cancels" are checked prior to actually performing any airborne action. See [[Jump#Airborne cancels]]. | As with all airborne actions, a variety of "cancels" are checked prior to actually performing any airborne action. See [[Jump#Airborne cancels]]. | ||

Notice that there is no code handling air steps for ledge grabbing or hanging on a ceiling, so such transitions are impossible. | Notice that there is no code handling air steps for ledge grabbing or hanging on a ceiling, so such transitions are impossible. | ||

Casually, tilt the joystick left to move left, right to move right, up to move down, down to move up. | |||

Key takeaways: | |||
* Pitching to move up happens faster with lower forward velocity. Try to be just under 4 or 16 forward velocity. | |||

* However, the pitch is capped to within +- 0x2AAA (in decimal: 10922) | |||
* '''TODO:''' I heard moving down then up can be faster then just the direct line. Explain big picture movements, what happens in a practical example. | |||
* In summary: | |||
# Joystick inputs affect (pitch,yaw) velocity. | |||
# Yaw velocity affects yaw, roll, and forward velocity. | |||
# Pitch affects forward velocity. | |||
# Forward velocity affects pitch. | |||
# Pitch velocity affects pitch. | |||
# x,y,z velocity is more or less directly exactly correspondent to forward velocity, pitch, and yaw. | |||
