Functions ¶

func DrawWallsToImage ¶

func DrawWallsToImage(walls []image.Rectangle, img *image.RGBA)

DrawWallsToImage draws the wall rectangles onto an RGBA image

func FillRectangle ¶

func FillRectangle(img *image.RGBA, rect image.Rectangle, fillColor color.Color)

FillRectangle is a utility function to fill a single rectangle on an RGBA image

Types ¶

type Cell ¶

type Cell struct {
	X, Y    int
	Visited bool
	Walls   [4]bool // North, East, South, West
}

Cell represents a single cell in the maze grid

type Direction ¶

type Direction int

Direction represents the four cardinal directions

const (
	North Direction = iota
	East
	South
	West
)

type MazeGenerator ¶

type MazeGenerator struct {
	WallThickness int
	Width, Height int
	CellSize      int
	Grid          [][]Cell
	// contains filtered or unexported fields
}

MazeGenerator holds the maze state

func NewMazeGenerator ¶

func NewMazeGenerator(width, height, cellSize, wallThickness int) *MazeGenerator

NewMazeGenerator creates a new maze generator

func (*MazeGenerator) GenerateMaze ¶

func (mg *MazeGenerator) GenerateMaze() []image.Rectangle

GenerateMaze creates a maze using depth-first search algorithm

func (*MazeGenerator) Size ¶ added in v1.1.0

func (mg *MazeGenerator) Size() image.Point

Size returns the size of the maze in pixels.

The size is calculated as the number of cells multiplied by the cell size, plus the wall thickness to account for the walls around the maze.
