mpVue实现小程序签到金币掉落动画(api实现)_晚秋_前端开发者

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

<template>
 <div class="container" v-if='isShow'>
  <!-- 创建金币对象 -->
  <!-- 大金币 -->
  <div :class="coinShow?'coinShow bgCoin':'bgCoin'" :animation="bgCoinAnimation" ></div>
  <!-- 7个小金币 -->
  <div :class="coinShow?'coinShow coin coin1':' coin coin1'" :animation="coinAnimation1">1</div>
  <div :class="coinShow?'coinShow coin coin2':' coin coin2'" :animation="coinAnimation2">2</div>
  <div :class="coinShow?'coinShow coin coin3':' coin coin3'" :animation="coinAnimation3">3</div>
  <div :class="coinShow?'coinShow coin coin4':' coin coin4'" :animation="coinAnimation4">4</div>
  <div :class="coinShow?'coinShow coin coin5':' coin coin5'" :animation="coinAnimation5">5</div>
  <div :class="coinShow?'coinShow coin coin6':' coin coin6'" :animation="coinAnimation6">6</div>
  <div :class="coinShow?'coinShow coin coin7':' coin coin7'" :animation="coinAnimation7">7</div>
 </div>
</template>
<script>
 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(()=>{
   this.coinShow =true
      var animation = wx.createAnimation({
       duration:300,
   timingFunction: 'ease-in-out',
  })
      var animation2 = wx.createAnimation({
       duration:300,
   timingFunction: 'ease-in-out',
  })
   animation.translate3d(0,-1000,0).step()
   animation2.translate3d(0,-1000,0).step().scale(1).step()
    this.bgCoinAnimation = animation2.export()
    this.coinAnimation1 = animation
    this.coinAnimation2 = animation
    this.coinAnimation3 = animation
    this.coinAnimation4 = animation
    this.coinAnimation5= animation
    this.coinAnimation6 = animation
    this.coinAnimation7 = animation
   setTimeout(()=>{
    this.isShow = false
   },500)
  },4000)
   }
   },
  mounted () {
  },
  onShow(){
  }
 }
</script>
<style lang="scss" scoped>
.container{
 position:absolute;
 top:0;
 left: 0;
 width: 100%;
 height: 100vh;
 // z-index: 999;
 background: rgba(5, 5, 5,0.5)
}
.bgCoin{
 background: rgb(233, 201, 19);
 border-radius: 50%;
 width: 100rpx;
 height: 100rpx;
 position: absolute;
 left: 350rpx;
 margin-left:-50rpx;
 top:600rpx;
  text-align: center;
  line-height: 100rpx;
  color: #ffffff;
  transform:rotate(180deg);
  transform:translate3d(0,-1000rpx,0);
}
.coinShow{
 opacity: 0;
}
.coin{
 background: rgb(233, 201, 19);
 border-radius: 50%;
 width: 50rpx;
 height: 50rpx;
  position: absolute;
  font-size: 24rpx;
  text-align: center;
  line-height: 40rpx;
  color: #ffffff;
  transform:translate3d(0,-1000rpx,0);
}
.coin1{
 top:40rpx;
 left:60rpx;
}
.coin2{
 top:90rpx;
 left:200rpx;
}
.coin3{
 top:860rpx;
 left:250rpx;
}
.coin4{
 top:150rpx;
 left:600rpx;
}
.coin5{
 top:270rpx;
 left:500rpx;
}
.coin6{
 top:490rpx;
 left:580rpx;
}
.coin7{
 top:350rpx;
 left:150rpx;
}
</style>

使用 引入组件

<template>
  <view>
   <view @click="clockInAnimation">立即签到</view>
 <clockAnimation :isShow="clockIsShow" ref="clockAnimation"></clockAnimation>
 </view>
</template>
<script>
     //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();
  },
  }
</script>
