info

Rotators are internally and automatically compressed, which reduces it's size in the network up to 90%. Their components are usually compressed into 1 byte each (with some exceptions which we need more precision).

🎒 Examples

local new_rotator = Rotator(-90, 153, 24.5)

🛠 Constructors

Default Constructor

local my_rotator = Rotator(pitch?, yaw?, roll?)
TypeNameDefaultDescription
numberpitch0Pitch
numberyawpitchYaw
numberrollpitchRoll

🧽 Properties

TypeNameDescription
numberPitchRotation around the right axis (around Y axis), Looking up and down (0=Straight Ahead, +Up, -Down)
numberYawRotation around the up axis (around Z axis), Running in circles 0=East, +North, -South.
numberRollRotation around the forward axis (around X axis), Tilting your head, 0=Straight, +Clockwise, -CCW.
