Types

type Animation

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

func NewAnimation

func NewAnimation(sz image.Point) *Animation

func (*Animation) Delay

func (*Animation) Delay() time.Duration

func (*Animation) Image

func (a *Animation) Image() image.Image

func (*Animation) Next

func (a *Animation) Next() error

type Field

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

Field represents a two-dimensional field of cells.

func NewField

func NewField(w, h int) *Field

NewField returns an empty field of the specified width and height.

func (*Field) At

func (f *Field) At(x, y int) color.Color

func (*Field) Bounds

func (f *Field) Bounds() image.Rectangle

Bounds return the topology of the Canvas

func (*Field) ColorModel

func (*Field) ColorModel() color.Model

ColorModel returns the canvas' color model, always color.RGBAModel

func (*Field) Get

func (f *Field) Get(x, y int) color.RGBA

Get returns the specified cell. If the x or y coordinates are outside the field boundaries they are wrapped toroidally. For instance, an x value of -1 is treated as width-1.

func (*Field) Next

func (f *Field) Next(x, y int) color.RGBA

Next returns the state of the specified cell at the next time step.

func (*Field) Set

func (f *Field) Set(x, y int, c color.RGBA)

Set sets the state of the specified cell to the given value.

type Life

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

Life stores the state of a round of Conway's Game of Life.

func New

func New(w, h int) *Life

New returns a new Life game state with a random initial state.

func (*Life) Step

func (l *Life) Step()

Step advances the game by one instant, recomputing and updating all cells.
