用javascript+jquery编写的小游戏-贪吃蛇(双人对战版)

前言

这是我在多年前初学jquery, 并结合javascript, 编写的一个小游戏.那洋洋洒洒几千行的js代码时刻提醒着我"不忘初心!".

引入文件

由于用到了jquery, 所以需要引入js文件

<script src="../js/jquery-3.2.1.js" type="text/javascript"></script>
<script src="../js/jquery.color.js" type="text/javascript"></script>

关键代码

这个游戏最关键的点是如何通过键盘按键让小蛇动起来, 之后画背景图, 障碍物, 改变颜色, 生成豆子, 计算碰撞都是很简单的. 部分代码如下:

        // 蛇身跟蛇头走
        for(var i = redBodys.length-1;i>0;i--){
            redBodys[i].style.top = redBodys[i - 1].style.top;
            redBodys[i].style.left = redBodys[i - 1].style.left;
        }
        // 红蛇头移动
        red1.style.left = redLeft + "px";
  1. 动起来及加减速的主要方法是setInterval().
  2. 创建一个数组代表小蛇的身体, 每个元素(这里可以抽象成对象, 每一节身体可以有颜色坐标等属性)代表一节身体, 只需要控制蛇头的移动和上下左右的方向判断, 并记录下蛇头的位置和历史位置, 数组中的元素依次获得上一个元素的历史位置并改变, 即可实现小蛇的移动效果.
