Functions

func HighlightSquares

func HighlightSquares(win *pixelgl.Window, squares BoardMap, coords chessapi.ValidDestinations, color color.RGBA)

HighlightSquares adds a visual marker to the list of board squares

func NewPieceRenderer

func NewPieceRenderer(win *pixelgl.Window) (pieces, error)

NewPieceRenderer builds a pieces instance that is responsible for drawing chess pieces

Types

type Board

type Board struct {
	Squares              BoardMap
	SquareOriginByCoords map[chessapi.Coord][]float64
}

func NewBoard

func NewBoard(
	originX, originY, size float64,
	blackFill, whiteFill color.RGBA,
) Board

NewBoard returns an array of *imdraw.IMDraw instances, each representing one square on a chess boardview. The size argument defines the width and height of each square. The blackFill and whiteFill arguments define what colors are used for the "black" and "white" squares.

func (*Board) GetCoord

func (board *Board) GetCoord(vec pixel.Vec) (chessapi.Coord, bool)

type BoardMap

type BoardMap map[chessapi.Coord]Square

BoardMap is the type used to describe the map of board squares/shapes

type Square

type Square struct {
	Shape   *imdraw.IMDraw
	OriginX float64
	OriginY float64
}

Square represents one square of the board

func FindSquareByVec

func FindSquareByVec(squares BoardMap, vec pixel.Vec) *Square

FindSquareByVec finds a square from the board map by it's (x,y) coordinate
