Types

type Tween

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

Tween interpolates two Params over time. Use NewTween() to create a new Tween.

func NewTween

func NewTween(start, end *gfx.Params, duration time.Duration, offset time.Duration, looping bool) *Tween

NewTween returns a new Tween for two Params, where start and end are the two Params to be interpolated. offset indicates the duration after which the interpolation starts. looping indicates if the interpolation should go back to the beginning when the end is reached.

func (*Tween) Finished

func (t *Tween) Finished() bool

Finished indicates if the animation is at the end.

func (*Tween) GetParams

func (t *Tween) GetParams() *gfx.Params

GetParams returns the interpolated Params.

func (*Tween) Update

func (t *Tween) Update(delta time.Duration)

Update updates the tweened Params.
