Hilo是一个跨终端的互动游戏解决方案。
官网：http://hiloteam.github.io/index.html
马上就要端午节了，公司要做一个接粽子的小游戏。网上找了一圈后决定用阿里团队的Hilo库进行开发。
游戏页面
游戏代码目录
1.安装hilo
npm install hilojs –save
2.index.vue
<template>
<div class="hilo" ref="hilo">
<div class="gameInfo">
<div class="score">{{score}}</div>
<div class="time">{{gameTime}}s</div>
</div>
<van-popup v-model="scorePopup" style="background: none;overflow: initial;">
<div class="scorePopup">
<div class="scorePopup-title">您本次游戏</div>
<div class="scorePopup-score">
{{score}}分
</div>
</div>
</van-popup>
</div>
</template>
<script>
import Hilo from "hilojs";
import Game from "./js/game";
export default {
name: '',
data() {
return {
game: new Game(),
scorePopup: false
};
},
watch: {
gameTime(val) {
if (val == 0) { //游戏结束
setTimeout(() => {
this.scorePopup = true;
}, 1500);
}
}
},
computed: {
score() {
return this.game.score
},
gameTime() {
return this.game.gameTime
}
},
methods: {
},
mounted() {
this.game.page = this.$refs.hilo;
this.game.init();
},
}
</script>
3.游戏图片资源预加载 Asset.js
游戏界面创建前可先加载游戏内需要的图片资源
使用Hilo的LoadQueue的队列下载工具。
export default Hilo.Class.create({
Mixes: Hilo.EventMixin,
queue: null, // 下载类
bg: null, // 背景
bigzZongzi: null, // 大粽子
zongzi: null, // 小粽子
fruit: null, // 香蕉
hand: null, // 手
beginBtn: null, // 开始按钮
score0: null, // -1分
score1: null, // +1分
score2: null, // +2分
load() {
let imgs = [{
id: 'bg',
src: './images/bg.png'
},
{
id: 'bigzZongzi',
src: './images/bigzZongzi.png'
},
{
id: 'zongzi',
src: './images/zongzi.png'
},
{
id: 'fruit',
src: './images/fruit.png'
},
{
id: 'hand',
src: './images/hand.png'
},
{
id: 'beginBtn',
src: './images/beginBtn.png'
},
{
id: 'score0',
src: './images/score0.png'
},
{
id: 'score1',
src: './images/score1.png'
},
{
id: 'score2',
src: './images/score2.png'
}
];
this.queue = new Hilo.LoadQueue();
this.queue.add(imgs);
this.queue.on('complete', this.onComplete.bind(this));
this.queue.start();
},
onComplete() { //加载完成
this.bg = this.queue.get('bg').content;
this.bigzZongzi = this.queue.get('bigzZongzi').content;
this.zongzi = this.queue.get('zongzi').content;
this.fruit = this.queue.get('fruit').content;
this.hand = this.queue.get('hand').content;
this.beginBtn = this.queue.get('beginBtn').content;
this.score0 = this.queue.get('score0').content;
this.score1 = this.queue.get('score1').content;
this.score2 = this.queue.get('score2').content;
//删除下载队列的complete事件监听
this.queue.off('complete');
// complete暴露
this.fire('complete');
}
})
4.游戏舞台对象 game.js
import Asset from './Asset'
import Zongzi from './Zongzi'
import Hand from './hand'
export default class game {
constructor(page) {
this.page = page
//设置的游戏时间
this.setGameTime = 30
this.gameTime = 0
this.gameStatus = "ready"
/*
play 游戏开始
ready 游戏结束
**/
// 下载队列
this.asset = new Asset()
// 画布对象
this.stage = null
// 画布信息
this.width = innerWidth * 2
this.height = innerHeight * 2 < 1334 ? innerHeight * 2 : 1334
this.scale = 0.5
// 定时器对象
this.ticker = null
//粽子对象
this.Zongzi = null
//粽子下落速度
this.enemySpeed = 700
//粽子生成速度
this.createSpeed = 400
//接粽子的手
this.hand = null
//开始按钮
this.beginBtn = null
//分数
this.score = 0
}
init() {
this.asset.on('complete', function () {
this.asset.off('complete')
this.initStage()
}.bind(this));
this.asset.load()
}
initStage() {
// 舞台
this.stage = new Hilo.Stage({
renderType:'canvas',

this.stage.enableDOMEvent([Hilo.event.POINTER_START, Hilo.event.POINTER_MOVE, Hilo.event.POINTER_END]);
// 启动定时器刷新页面 参数为帧率
this.ticker = new Hilo.Ticker(60)
// 舞台添加到定时队列中
this.ticker.addTick(this.stage)
// 添加动画类到定时队列
this.ticker.addTick(Hilo.Tween);
//启动ticker
this.ticker.start(true);
this.initBg();
this.initBeginBtn();
//this.initZongzi();
//this.initHand();
}
initBg() { //初始化背景
let bgImg = this.asset.bg;
new Hilo.Bitmap({
id: 'bg',
image: bgImg,
scaleX: this.width / bgImg.width,
scaleY: this.height / bgImg.height
}).addTo(this.stage);
}
initBeginBtn() { //初始化开始按钮
this.beginBtn = new Hilo.Bitmap({
id: 'beginBtn',
image: this.asset.beginBtn,

this.beginBtn.on(Hilo.event.POINTER_START, this.startGame.bind(this))
}
startGame() { //开始游戏
this.initZongzi();
this.initHand()
//this.beginBtn.removeFromParent()
this.stage.removeChild(this.beginBtn)

this.score = 0;
this.gameStatus = "play"
this.calcTime()
}
calcTime() { //游戏时间
setTimeout(() => {
if (this.gameTime > 0) {
this.gameTime--;
this.calcTime()
} else {
this.gameOver()
}
}, 1000);
}
gameOver() {//游戏结束
this.Zongzi.stopCreateEnemy()
this.gameStatus = "ready"
this.initBeginBtn()
//this.hand.removeChild(this.hand.score)
this.stage.removeChild(this.hand)
}
initZongzi() {//初始化粽子
this.Zongzi = new Zongzi({
id: 'Zongzi',
height: this.height,
this.width,
enemySpeed: this.enemySpeed,

pointerEnabled: false, // 不关闭事件绑定 无法操作舞台
zongziList: [this.asset.bigzZongzi, this.asset.zongzi, this.asset.fruit]
}).addTo(this.stage, 2)
//舞台更新
this.stage.onUpdate = this.onUpdate.bind(this);
}
initHand() {//初始化手
this.hand = new Hand({
id: 'hand',
img: this.asset.hand,
height: this.asset.hand.height,
this.asset.hand.width,
x: this.width / 2 - this.asset.hand.width / 2,
y: this.height - this.asset.hand.height + 30
}).addTo(this.stage, 1);
Hilo.util.copy(this.hand, Hilo.drag);
this.hand.startDrag([-this.asset.hand.width / 4, this.height - this.asset.hand.height + 30, this.width - this.asset.hand.width / 2, 0]);
}
onUpdate() {//舞台更新
if (this.gameStatus == 'ready') {
return
}
this.Zongzi.children.forEach(item => {
if (this.hand.checkCollision(item)) {
// 碰撞了
item.over();
this.score += item.score;
switch (item.score) {
case -1:
this.hand.addScore(this.asset.score0)
break;
case 1:
this.hand.addScore(this.asset.score1)
break;
case 2:
this.hand.addScore(this.asset.score2)
