看了Vue官方教程(貌似和自己写的框架差别不大,听前前端同事一直吹Vue,于是学习了一下,和自己写的框架好像也没强哪里去嘛,就是要傲娇哈哈),等有空也整理自己的框架,开源好了),想找个项目练练手(没找到好的),就写个飞机大战吧。
飞机大战总共三个页面:登录、匹配、游戏页面,三个页面的功能:
1、 登录:玩家填写用户名,socket连接
2、匹配:等待其他玩家准备
3、游戏:战斗页面
上述流程仿照了王者荣耀,所以就叫王者飞机(当然和王者荣耀相差十万八千里)最终效果:

根据上面的设计,Vue套餐基本就都用上了。
首先,先编写游戏页面(让飞机动起来):

我们定义一下玩家类player.js:

export default class Player {
  constructor (name, x, y, enermy = false) {
    this.name = name // 玩家名称
    this.position = {} // 位置
    this.position.x = x
    this.position.y = y
    this.speed = 1
    this.direct = 0 //  方向0:朝上,1朝左,2朝下,3朝右
    this.attack = 1 // 攻击力
    this.flood = 5 // 血量
    this.sock = null // socket连接
    this.state = 0 // 0:停止,1:移动
    this.bullets = [] // 发射的子弹
    this.enermys = [] // 敌人
    if (!enermy) {
      this.init()
    }
  }
  init () {
    // TODO: WebSocket连接
  }
  move (direct) {
    this.direct = direct
    switch (direct) {
      case 0:
        if (this.position.y > 0) {
          this.position.y -= this.speed
        }
        break
      case 1:
        if (this.position.x > 0) {
          this.position.x -= this.speed
        }
        break
      case 2:
        if (this.position.y < window.innerHeight - 55) {
          this.position.y += this.speed
        }
        break
      case 3:
        if (this.position.x < window.innerWidth - 55) {
          this.position.x += this.speed
        }
        break
    }
  }
}

玩家类的具体信息参照注释。
接下来编写Game.vue组件

<template>
  <div class = "scene">
    <div v-for="(monster,index) of monsters" :key="index" class="monster" :style="{left:monster.position.x + ‘px‘,top:monster.position.y + ‘px‘}">
      <img src="../assets/monster.png"
           :class="{‘turn-left‘:monster.direct == 1,‘turn-right‘:monster.direct == 3,‘turn-up‘:monster.direct == 0,‘turn-down‘:monster.direct == 2}"/>
      <p>{{ monster.name }}</p>
    </div>
    <span v-for="(monster,index) of monsters" :key="index">
      <div class="bullet" v-for="(bullet,index2) of monster.bullets"
           :key = "index2"
           :style="{left:bullet.position.x + ‘px‘,top:bullet.position.y + ‘px‘}">
      </div>
    </span>
    <div class = "monster"
         :style="{left:own.position.x + ‘px‘,top:own.position.y + ‘px‘}">
      <img src="../assets/monster.png"
           :class="{‘turn-left‘:own.direct == 1,‘turn-right‘:own.direct == 3,‘turn-up‘:own.direct == 0,‘turn-down‘:own.direct == 2}"/>
      <p>{{ own.name }}</p>
    </div>
    <div class="bullet" v-for="(bullet,index) of own.bullets"
         :key = "index"
         :style="{left:bullet.position.x + ‘px‘,top:bullet.position.y + ‘px‘}">

    </div>
    <div class = "play-control">
      <div>
        <div @touchstart="turn(0)" @touchend="turnEnd()" class="up"></div>
      </div>
      <div style="text-align: initial;">
        <div @touchstart="turn(1)" @touchend="turnEnd()" class="left"></div>
        <div @touchstart="turn(3)" @touchend="turnEnd()" class="right"></div>
        <div class="clear"></div>
      </div>
      <div>
        <div @touchstart="turn(2)" @touchend="turnEnd()" class = "down"></div>
      </div>
    </div>
    <div class = "shoot-control" @touchstart="shoot()">
    </div>
  </div>
</template>

<script>
import Player from ‘../player‘
export default {
  name: ‘game‘,
  data () {
    return {
      own: new Player(‘test‘, Math.round(Math.random() * window.innerWidth), Math.round(Math.random() * window.innerHeight)),
      monsters: []
    }
  },
  methods: {
    turn (direct) {
      this.own.move(direct)
    },
    turnEnd () {
    },
    shoot () {
    }
  }
}

  border-radius: 200px;
  background-size: 100%;
  background: url(../assets/BButton.png) no-repeat;
}
</style>

现在点击方向盘飞机就动起来了,然而需要不停的点击按键,显然不合理,所以我们使用requestAnimationFrame()方法实现动画,在Game组件中添加代码:

 mounted () {
    let that = this
    function _callback () {
      for (let monster of that.own.enermys) {
        monster.onframe()
        for (let bullet of monster.bullets) {
          bullet.onframe()
        }
      }
      that.own.onframe()
      for (let bullet of that.own.bullets) {
        bullet.onframe()
      }
      requestAnimationFrame(_callback)
    }
    _callback()
  }

添加player的onframe代码:

onframe () {
    if (this.state === 1) {
      this.move(this.direct)
      this.send({ opt: ‘upposition‘, name: this.name, x: this.position.x, y: this.position.y, direct: this.direct })
    }
  }

当方向盘touchstart时own.state置为1,当touchend时置为0,修改方法:

turn (direct) {
      this.$store.dispatch(‘move‘, direct)
    },
    turnEnd () {
      this.$store.dispatch(‘turnEnd‘)
    },

至此,当按下方向键时,飞机开始运动,当放开方向键时,飞机停止运动。
下一篇将实现NodeJs实现WebSocket游戏服务端的逻辑
