Functions

func Norm

func Norm(a float64) float64

Norm normalizes angle between <-math.Pi, math.Pi>

func Random

func Random() float64

Random returns random angle in range <-math.Pi, math.Pi>

func To

func To(a, b float64) float64

To returns shortest step form a to b

assuming angles are ranging from <-math.Pi, math.Pi>

func Turn

func Turn(start, dest, vel float64) float64

Turn turns the angle from start to dest by velocity, always the shorter way

assuming angles are ranging from <-math.Pi, math.Pi>
