Types

type Terminator 

type Terminator interface {
	image.Image

	Clear()
	Height() int
	LineFeed()
	Publish(s string)
	Runes() []rune
	String() string
	Width() int
}

type Type 

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

Type represents a fantasy virtual machine.

func (*Type) At 

func (receiver *Type) At(x, y int) color.Color

func (*Type) Bounds 

func (receiver *Type) Bounds() image.Rectangle

func (*Type) ColorIndex 

func (receiver *Type) ColorIndex(c color.Color) uint8

func (*Type) ColorModel 

func (receiver *Type) ColorModel() color.Model

func (*Type) Colorize 

func (receiver *Type) Colorize(a ...interface{}) error

Colorize sets the color palette.

Example

Here are some examples of Colorize being used: 

err := machine.Colorize("tia")

func (*Type) Draw 

func (receiver *Type) Draw(img image.Image) error

func (*Type) DrawDye 

func (receiver *Type) DrawDye(color color.Color) error

func (*Type) DrawPixel 

func (receiver *Type) DrawPixel(x int, y int, color color.Color) error

func (*Type) Frame 

func (receiver *Type) Frame() []uint8

func (*Type) Image 

func (receiver *Type) Image() draw.Image

func (*Type) Map 

func (receiver *Type) Map() image.Image

func (*Type) Memory 

func (receiver *Type) Memory() []uint8

func (*Type) Palette 

func (receiver *Type) Palette() palette2048.Slice

Palette provides access to the machines palette.

Example 
var machine c80machine.Type

// We set the RGBA values of each of the colors in the palette.
//
// (“RGBA” = Red, Green, Blue, Alpha.)
//
// The colors in the palette are indexed from 0 to 15.
//
// So, here, color №5 is rgba(118,38,113,255).
//
// And, also here, color №0 is rgba(1,1,1,255).
machine.Palette().SetColorRGB(0, 1, 1, 1)
