Class: Animation

一般通过AnimationSystem来创建实例

// 通常调用animationSystem的anime方法来创建实例:
let animation = stage.animationSystem.anime({
   from: 0,
   to: 1,
   update: (n) => {
       //flashBall.y = -100 * (1 - n);
   },
   effect: 'easeInQuart',
   duration: 1000,
   times: Infinity,
   direction: 'alternate'
});

// 播放
animation.play();

// play() 返回一个Promise对象
animation.play().then(function(){
   // 播放结束后的处理
});

// 暂停
animation.pause();

// 取消
animation.cancel();

Constructors

constructor

new Animation(from?, to?, duration?, update?)

start 、end 可以是数字，也可以是包含数字的数组

创建实例时start、end、time、action参数可以为空， 但是调用play()方法之前要确保都已经被赋过值。

Parameters

Name	Type	Description
from?	AnimationFrameData
to?	AnimationFrameData
duration?	number	动画事件
update?	Function	动画每一帧时执行的动作函数

Properties

currentTime

currentTime: number

---

delay

delay: number = 0

设置动画开始之前的延迟时间，默认为 0

---

delayed

delayed: boolean = false

---

direction

direction: "normal" | "reverse" | "alternate" | "alternate-reverse" = 'normal'

运动方向（animation-direction） --normal 是正常运动

--reverse 反向运动

--alternate 运动完后，动画返回

--alternate-reverse 反向运动完后，动画返回

---

duration

duration: number = 1000

持续时间, 默认为 1000 毫秒

---

effect

effect: EasingNames = 'easeLinear'

---

finished

finished: boolean = false

---

from

from: AnimationFrameData

初始数据集

---

isPause

isPause: boolean = false

---

name

Optional name: string

名称

---

onEnd

Optional onEnd: Function

结束时的回调函数

---

playState

playState: "idle" | "pending" | "running" | "paused" | "finished" = 'idle'

能够返回并设置一个可枚举值来描述一个动画的回放状态。

---

playedTimes

playedTimes: number = 0

已经播放了多少次

---

startTime

startTime: number

开始时间

---

times

times: number = 1

重复次数（animation-iteration-count），默认1 --可设置数值如： 5 --也可设置为无限次: Infinity

---

to

to: AnimationFrameData

结束数据集

---
