Types

type Fov

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

func New

func New(blocksSightFn func(space.Location) bool,
	markSeenFn func(image.Point, space.Location),
	mf *space.Manifold) *Fov

func (*Fov) Run

func (f *Fov) Run(origin space.Location, radius int)

Run runs a field-of-view computation up to radius distance from the given origin, and calls the fov object's markSeenFn callback for all locations it finds visible. The blocksSightFn callback of fov object is used to determine locations that block visibility.
