JavaScript游戏之仿劲舞团(简陋版)
时间:2010-10-19 来源:Floyd
这次带来的是仿劲舞团的小游戏。。。就是上下左右。。按后按空格。。。不过,没有人跳舞,也没有背景音乐。。。简陋版嘛
先来个预览玩玩吧:
连击:0

1:Direction类,方向类,就是显示上下左右那些,主要负责生成对应的dom元素。
Direction类 1 //方向类,生成上下左右的方向Dom2 //direction:方向

4

6
7 this.init(direction);

3:Game类,游戏控制类,控制游戏的开始结束,以及倒计时等。
游戏控制类 1 //游戏控制类2 var Game = {
