import UIKit
import PlaygroundSupport
import IBAnimatable

//: Set up the iPhone View
let iPhoneView = PhoneView()
PlaygroundPage.current.liveView = iPhoneView

//: Set up the animatable View
let view = CircleView()
iPhoneView.addSubview(view)

//: animationType: all supported predefined animations can be found in `enum AnimationType`
let animationType: AnimationType = .squeeze(way: .in, direction: .left)

//: duration: used to specify the duration of animation. Default value is 0.7
let duration: TimeInterval = 1

//: delay: used to delay the animation in seconds. Default value is 0
let delay: TimeInterval = 1

//: damping: used in UIView Spring animation (0 ~ 1). To smoothly decelerate the animation without oscillation, use a value of 1. Employ a damping ratio closer to zero to increase oscillation. Default is 0.7. Notice: FadeOutIn, FadeInOut, Shake, Pop, Morph, Squeeze, Flash, Wobble and Swing animations do not use damping.
let damping: CGFloat = 0.8

//: velocity: used in UIView Spring animation. A value of 1 corresponds to the total animation distance traversed in one second. For example, if the total animation distance is 200 points and you want the start of the animation to match a view velocity of 100 pt/s, use a value of 0.5. Default is 0.7. Notice: FadeOutIn, FadeInOut, Shake, Pop, Morph, Squeeze, Flash, Wobble and Swing animations do not use damping.
let velocity: CGFloat = 2

//: force: used to apply force to the animation. The number is higher, the animation property has more changes. eg. for Pop animation, higher force causes the view poping bigger. Default is 1
let force: CGFloat = 1

view.animate(animationType, duration: duration, damping: damping, velocity: velocity, force: force)
    .delay(delay)
    .then(.shake(repeatCount: 3), duration: duration, damping: damping, velocity: velocity, force: force)
    .completion {
      print("animation done")
    }
