CSS3 Javascript

520和女朋友搞点不一样的礼物， html+css+js做一个网页版坦克大战游戏

坦克游戏玩法及介绍

我们先来看一下首页。

打开这个首页很简单，基本是上面这个样子，然后选择两个人回车就可以进行玩耍了，这个游戏需要两个人一起操作，玩家1（我）：使用WASD四个键进行上左下右方向的控制，通过space键进行设计射击。玩家2（女朋友）：通过方向键上下左右控制方向，通过enter键盘射击。基本上我控制整个电脑键盘的左边，她控制电脑键盘的右边。通过N键进行下一关，P键选择上一关。再键盘上显示如下。

演示如何进入游戏

通过方向键的下键选择两个人，然后点击回车进入游戏。也可以选择一个人进行回车进行战斗。

一个人战斗的状态。

两个人战斗的状态。

比如图中红色标记的砖头是打不破的，只能绕道走，还有只能再yellow标记的区域内操作，其它砖头用子弹就可以打破，不能让对手先打破你的大本营（我右边中间的老鹰），不然又得GG.

整个游戏规则大体是这样，下面看一下代码。

项目结构

整个项目由五部分组成，分为背景音乐、基础样式、动图、核心JS及首页静态展示。不涉及后端，纯前端实现。
