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。

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。

至于这个游戏规则我想大家都应该知道,这个里面的砖头可以打破,对手可以被打到,不能自己人打自己人,最外层的墙不能打破,坚硬的砖头也不能打破。把对手打完就可以进行下一关,不要先被对手的子弹打到,不然你就GG了。

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。
