这里使用小程序自带的api来实现，用小程序来写动画的恶心点在于，没有帧，只能用setimeout 来作为帧来使用，
下面是实现代码， 下面是简单用div代替了图片，需要什么图片，可以自行替换相应的div即可
需要变成原生小程序，则需要修改一下代码的写法
效果图：
创建金币动画组件 clockAnimation.vue
export default{
data() {
return {
coinShow:false,//金币对象是否显示，用于重置动画时，隐藏对象
isShow:false, //遮罩显示
//大金币动画
bgCoinAnimation:{},
//小金币动画
coinAnimation1:{},
coinAnimation2:{},
coinAnimation3:{},
coinAnimation4:{},
coinAnimation5:{},
coinAnimation6:{},
coinAnimation7:{},
}
},
methods: {
//动画
animation(){
this.coinShow =false
this.isShow = true
this.bgAnimation()
this.smallAnimation()
},
//大金币动画
bgAnimation(){
var animation = wx.createAnimation({
duration:1000,
timingFunction: 'ease-in-out',
})
this.timer = setTimeout(()=>{
animation.translate3d(0,30,0).step().translate3d(0,0,0).step().rotate(80).step({duration:400}).rotate(0).step({duration:500})
this.bgCoinAnimation = animation.export()
},100)
setTimeout(()=>{
animation.opacity(0).scale(4).step()
this.bgCoinAnimation = animation.export()
},3000)
},
//小金币动画
smallAnimation(){
var animation = wx.createAnimation({
duration:1000,
timingFunction: 'ease-in-out',
})
animation.translate3d(0,30,0).step().translate3d(0,0,0).step()
setTimeout(()=>{
this.coinAnimation1 = animation
},300)
setTimeout(()=>{
this.coinAnimation2 = animation
},500)
setTimeout(()=>{
this.coinAnimation3 = animation
},600)
setTimeout(()=>{
this.coinAnimation4 = animation
},700)
setTimeout(()=>{
this.coinAnimation5 = animation
},800)
setTimeout(()=>{
this.coinAnimation6 = animation
},900)
setTimeout(()=>{
this.coinAnimation7 = animation.export()
},1000)
//小金币掉落动画
setTimeout(()=>{
animation.translate3d(0,1000,0).step()
this.coinAnimation1 = animation
this.coinAnimation2 = animation
this.coinAnimation3 = animation
this.coinAnimation4 = animation
this.coinAnimation5= animation
this.coinAnimation6 = animation
this.coinAnimation7 = animation
},3000)
//动画结束，重置动画初始位置
setTimeout(()=>{

var animation = wx.createAnimation({

animation.translate3d(0,-1000,0).step()

this.coinAnimation4 = animation
this.coinAnimation5= animation
this.coinAnimation6 = animation
this.coinAnimation7 = animation
setTimeout(()=>{
this.isShow = false
},500)
},4000)
}
},
mounted () {
},
onShow(){
}
}
.container{

使用 引入组件
立即签到
//引入组件
import clockAnimation from "../../components/clockAnimation.vue";
export default {
components: {
clockAnimation
},
data() {
return {
clockIsShow: false,
}
},
methods: {
clockInAnimation() {
this.clockIsShow = true;
this.$refs.clockAnimation.animation();
},
}
