Types

type Chunk

type Chunk struct {
	// contains filtered or unexported fields
}

func (Chunk) Draw

func (c Chunk) Draw(screen *ebiten.Image, offsetX int, offsetY int)

Draw (chunk) is used to draw the box for an entire chunk.

func (*Chunk) DrawChunkTiles

func (c *Chunk) DrawChunkTiles(screen *ebiten.Image, offsetX int, offsetY int)

func (*Chunk) SetX

func (c *Chunk) SetX(x int)

type Chunks

type Chunks map[string]*Chunk

func (Chunks) Draw

func (c Chunks) Draw(screen *ebiten.Image, offsetX int, offsetY int)

Draw is used to draw all of the chunks on the screen for debugging purposed. Currently this will draw every chunk, not get what is visible in the viewport.

const (
	ChunkSize  Unit = 32
	TileSize   Unit = 16
	ChunkPixel      = ChunkSize * TileSize
)

func (Unit) Int

func (*World) InitWorld

func (w *World) InitWorld(screenX, screenY int)

Init World renders all of the chunks of the map when first loading the map. Afterward new chunks will be detected and added in the Update game loop.

We break up rendering into 4 quadrants of the viewport in which the X and Y numbers will always remain positive or negative for simplicity. So far example only things in the top right quadrant of the viewport.
