Functions

func Distance

func Distance(x1, y1, x2, y2 int) float64

Distance is the euclidean distance function from two implicit int pairs

Types

type Point

type Point struct {
	X, Y int
}

Point is a basic integer pair

func NewPoint

func NewPoint(x, y int) Point

NewPoint returns an (X,Y) point structure

func (Point) Add

func (p Point) Add(p2 Point) Point

Add sums the location of a second point onto the Point

func (Point) Distance

func (p Point) Distance(p2 Point) float64

Distance is the euclidean distance function

func (Point) GreaterOf

func (p Point) GreaterOf(ps ...Point) Point

GreaterOf returns a point of the highest X and Y component in the inputs.

func (Point) LesserOf

func (p Point) LesserOf(ps ...Point) Point

LesserOf returns a point of the lowest X and Y component in the inputs.

func (Point) PointsBetween

func (p Point) PointsBetween(p2 Point) []Point

PointsBetween returns a line of points connecting p and p2

type Rect

type Rect struct {
	Min Point
	Max Point
}

Rect is a basic integer pair with width / height

func NewRect

func NewRect(x, y, x2, y2 int) Rect

NewRect returns an (X,Y):(X2,Y2) rectangle

func NewRectWH

func NewRectWH(x, y, w, h int) Rect

NewRectWH returns an (X,Y):(X+W,Y+H) rectangle

func ShuffleRects

func ShuffleRects(rs []Rect) []Rect

ShuffleRects is a utility function to randomize the order of a rectangle set
