Functions

func Btoc

func Btoc(b byte) (x, y int)

Btoc converts a coordinate byte to x,y coordinates.

func Ctob

func Ctob(x, y int) byte

Ctob converts a x,y coordinate with x,y < 16 to a coordinate byte.

func X

func X(b byte) int

X returns the x coordinate of a coordinate byte.

func Y

func Y(b byte) int

Y returns the y coordinate of a coordinate byte.

Types

type XY

type XY struct {
	X, Y int
}

XY represents a two dimensional x,y coordinate.
