Types

type BasicEffect

type BasicEffect struct {
	shared.TimeSpan
	Rank int
}

func (BasicEffect) Priotity

func (e BasicEffect) Priotity() int

type ColorFunc

type ColorFunc func(t time.Time) color.HSLA

ColorFunc is used by effects to provide colors. Often placed under Effect.color

func NewColorFuncHueBounce

func NewColorFuncHueBounce(colorStart, colorEnd color.HSLA, direction int, shiftFunc ShiftFunc) ColorFunc

NewColorFuncStatic creates a ColorFunc which produces shifting colors, bouncing between colorStart and colorEnd, starting at colorStart and shifting in the direction specified by upSpectrum

func NewColorFuncHueShift

func NewColorFuncHueShift(colorStart color.HSLA, shiftFunc ShiftFunc) ColorFunc

NewColorFuncStatic creates a ColorFunc which produces shifting colors starting at colorStart.

func NewColorFuncStatic

func NewColorFuncStatic(onlyColor color.HSLA) ColorFunc

NewColorFuncStatic creates a ColorFunc which only produces onlyColor.

type ShiftFunc

type ShiftFunc func(t time.Time) float32

func NewShiftFuncLinear

func NewShiftFuncLinear(start time.Time, shiftPerMillisecond float32) ShiftFunc

func NewShiftFuncSinusoidal

func NewShiftFuncSinusoidal(start time.Time, millisecondsPerCycle int, baseShiftPerMillisecond, rangeShift float32) ShiftFunc

type Solid

type Solid struct {
	BasicEffect
	Color ColorFunc
}

func (Solid) Render

func (e Solid) Render(t time.Time, lights []effect.Light) []color.HSLA
