Functions

func DrawMap 

func DrawMap(datadir string, m *maps.Map, opts *Options) (*image.RGBA, error)

DrawMap is a helper for drawing a single map. For multiple maps it's more efficient to use Renderer.

Types

type Options 

type Options struct {
	FailFast bool // return on the first error
	NoFloor  bool // do not draw floor tiles
	NoWalls  bool // do not draw walls
}

type Renderer 

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

Renderer is a Nox map renderer.

func NewRenderer 

func NewRenderer(datadir string) (*Renderer, error)

NewRenderer creates a Nox map renderer based on a given Nox data dir. The renderer can be sued to draw multiple maps.

func (*Renderer) Close 

func (r *Renderer) Close() error

Close the renderer,

func (*Renderer) DrawMap 

func (r *Renderer) DrawMap(m *maps.Map, opts *Options) (*image.RGBA, error)

DrawMap renders the map. It will keep processing the map and return a partial image in case of an error. If FailFast option is set, it will fail on the first error instead of returning the last one. Passing nil options will use defaults.

func (*Renderer) DrawMapFile 

func (r *Renderer) DrawMapFile(dir string, opts *Options) (*image.RGBA, error)

DrawMapFile reads and renders the map file. See DrawMap for details. As opposed to DrawMap, the returned image may be nil in case map decoding fails.
