JavaScript 实现锅拍灰太狼小游戏

1、项目文件

2、使用HTML及css进行页面布局

HTML部分

<div class="container">
        <h1 class="score">0</h1>
        <div class="progress"></div>
        <div id="start">
            <h2>锅打灰太狼</h2>
            <button class="start">开始游戏</button></div>
        <div class="rules">游戏规则</div>
        <div class="rule">
            <p>游戏规则:</p>
            <p>1.游戏时间:60s</p>
            <p>2.拼手速,殴打灰太狼+10分</p>
            <p>3.殴打小灰灰-10分</p>
            <a href="#" rel="external nofollow"  class="close">[关闭]</a>
        </div>
        <div class="mask">
            <h1>GAME OVER</h1>
            <button class="reStart">重新开始</button>
            <button class="finish">结束游戏</button>
        </div>
        <div id="finish">
            <h2>锅打灰太狼</h2>
            <h3>得分：<span class="scoreEnd"></span> </h3>
        </div>
    </div>

css部分

    margin: 0;
    padding: 0;
}

    position: absolute;
    top: 66px;
    left: 63px;
}

.container>#start>h2 {
    margin-top: 180px;
    color: white;
    text-align: center;
}

.container>#start>.start {
    width: 150px;
    line-height: 35px;
    text-align: center;
    color: white;
    background: linear-gradient(#E55C3D, #C50000);

    bottom: 0;
    text-align: center;
}

.container>.rule {
    width: 100%;
    height: 100%;
    background: rgba(0, 0, 0, 0.5);
    position: absolute;
    left: 0;

}

3、使用JavaScript来实现效果

var begin = document.querySelector('#start');
var h = begin.querySelector('h2');
var start = document.querySelector('.start'); //开始游戏按钮
var mask = document.querySelector('.mask'); //包含重新开始
var rules = document.querySelector('.rules'); //游戏规则
var rule = document.querySelector('.rule'); //游戏规则详细
var reStart = document.querySelector('.reStart'); //重新开始游戏按钮
var close = document.querySelector('.close'); //关闭
var progress = document.querySelector('.progress'); //进度条
var container = document.querySelector('.container'); //容器
var score = document.querySelector('.score'); //游戏分数
var finishBtn = document.querySelector('.finish'); // 结束游戏按钮
var finish = document.querySelector('#finish'); //结束游戏按钮
var scoreEnd = document.querySelector('.scoreEnd'); //最后得分
//点击开始游戏
start.onclick = function() {
    // console.log(123);
    // 隐藏按钮
    finish.style.display = 'none';
    var fadIndex = this.parentNode;
    fadIndex.style.display = 'none';
    // 设置进度条长度
    var progressWidth = 180;
    progressHandler(progressWidth);
    var timer;
    startAnimation(); //动画开始
};
// 规则
// console.log(rules);
rules.onclick = function() {
    console.log('点击游戏规则');
    rule.style.display = 'block';
};
// 关闭
close.onclick = function() {
    console.log('关闭');
    rule.style.display = 'none';
};
// 重新开始游戏
reStart.onclick = function() {
    score.innerHTML = 0;
    mask.style.display = 'none';
    // console.log(score.innerHTML);
    var progressWidth = 180;
    progress.style.width = '180px';
    progressHandler(progressWidth);
    startAnimation();
};
// 结束游戏按钮
finishBtn.onclick = function() {
        mask.style.display = 'none';
        finish.style.display = 'block';
        scoreEnd.innerHTML += score.innerHTML;
        begin.style.display = 'block';
        h.style.display = 'none';
        progress.style.width = 180 + 'px';
    }
    //进度条
function progressHandler(index) {
    // 设置计时器
    var setProgress = setInterval(function() {
        index--;
        progress.style.width = index + "px";
        if (index <= 0) {
            clearInterval(setProgress); //清除计时器
            mask.style.display = 'block';
            stopAnimation(); //停止动画
        }
    }, 100);
}
//开始动画
function startAnimation() {
    //定义两个数组存放图片
    var imgArr = ['./images/h0.png', './images/h1.png', './images/h2.png',
        './images/h3.png', './images/h4.png', './images/h5.png', './images/h6.png',
        './images/h7.png', './images/h8.png', './images/h9.png'
    ];
    var imgArr2 = ['./images/x0.png', './images/x1.png', './images/x2.png',
        './images/x3.png', './images/x4.png', './images/x5.png', './images/x6.png',
        './images/x7.png', './images/x8.png', './images/x9.png'
    ];
    // 定义一个数组保存所有可能出现的位置
    var arrPos = [{
        left: "98px",
        top: "115px"
    }, {
        left: "17px",
        top: "160px"
    }, {
        left: "15px",
        top: "220px"
    }, {
        left: "30px",
        top: "293px"

        left: "207px",
        top: "295px"
    }, {
        left: "200px",
        top: "211px"
    }, {
        left: "187px",
        top: "141px"
    }, {
        left: "100px",
        top: "185px"
    }];
    // 创建一个图片
    var imgs = document.createElement('img');
    imgs.setAttribute('class', 'wolfImages');
    //图片随机出现的位置
    var posIndex = Math.round(Math.random() * 8);
    //设置图片显示位置
    imgs.style.position = 'absolute';
    imgs.style.left = arrPos[posIndex].left;
    imgs.style.top = arrPos[posIndex].top;
    // console.log(img.style.left);
    // 随机获取数组类型
    var imgType = Math.round(Math.random()) == 0 ? imgArr : imgArr2;
    // 设置图片的内容 限定为第0张到第5张
    window.index = 0;
    window.indexEnd = 5;
    timer = setInterval(() => {
        if (index > indexEnd) {
            imgs.remove();
            clearInterval(timer);
            startAnimation();
        }
        imgs.setAttribute('src', imgType[index]);
        index++;
    }, 400);
    //添加图片
    container.appendChild(imgs);
    //分数
    scoreEverySum(imgs);

}
// 分数统计
function scoreEverySum(e) {
    e.onclick = function() {
        // 设置图片的内容 限定为第5张到第9张
        window.index = 5;
        window.indexEnd = 9;
        // 拿到当前点击图片的路径
        var src = this.getAttribute('src');
        // 根据图片地址判断
        // 根据点击的图片类型增减分数
        if (src.indexOf("h") >= 0) {
            score.innerHTML = parseInt(score.innerHTML) + 10;
        } else {
            score.innerHTML = parseInt(score.innerHTML) - 10;
        }
        e.onclick = null
    }
}
//停止动画
function stopAnimation() {
    var img = document.querySelector('.wolfImages');
    console.log(img);
    img.remove();
    clearInterval(timer);
