Types

type Animation

type Animation struct{}

func (*Animation) StartAnimation

func (a *Animation) StartAnimation(duration, delay time.Duration, maxRot, rotGap float64, cancel <-chan int)

type Camera

type Camera struct {
	X, Y, Rot, Scale, MaxScale, MinScale float64
	Width, Height                        int
	Animation
}

Camera can look at positions, zoom and rotate.

func NewCamera

func NewCamera(width, height int, x, y, rotation, zoom float64) *Camera

NewCamera returns a new Camera

func (*Camera) GetCameraOptions

func (c *Camera) GetCameraOptions() *ebiten.DrawImageOptions
