游戏的基本玩法：从"红色","黄色","绿色","蓝色","紫色","黑色",中随机选出一个字，然后将字的颜色设置成与文字不同的颜色，如：文字是红色，字体的颜色是黄色，然后让玩家选择字体的颜色，测试反应时间。

代码如下：

<span style="font-family:Courier New;">var MainLayer = cc.LayerColor.extend({
	init:function()
	{
		//初始化界面
		 //0:点击开始界面 1:表示等待界面，2:表示在点击界面 3:结果界面 4:Too soon界面
		this.flag = 0;
		this._super();
		this.size = cc.Director.getInstance().getWinSize();
		this.setColor(cc.c4(180,170,160,255));
		this.showToStart();
		
		//可触摸
		this.setTouchEnabled(true);
 
		//一些常量
		this.redColor = new Array(255,0);
		this.yellowColor = new Array(255,255,0);
		this.greenColor = new Array(0,0);
		this.blueColor = new Array(0,255 );
		this.purpleColor = new Array(139,255);
		this.blackColor = new Array(0,0);
 
		this.allColor = new Array(this.redColor,this.yellowColor,this.greenColor,this.blueColor,this.purpleColor,this.blackColor);
		this.allColorText = new Array("红色","黑色");
