项目中管理计时器太混乱难看了，用好听点的话来说就是代码不优雅。

 

想了下就随手简单写了个时间管理模块了。其实有好几种实现方式的，但是选用了U3D最为合适和简单的方式写。效率可能不高，但做小游戏是压根没问题的了。

 

原理简单点来说就是统一管理计时器。

 

每个计时器有自己的开始、暂停、结束、重新开始。当计时结束之后则调用相应的一个或者多个函数。

 

Timer.cs算是基类，TimerManager.cs则是管理每一个计时器的管理程序。根据不同的项目改至适用即可。

 

就那样，代码非常简单。就是一个委托回调。

 

具体代码放到GITHUB了，有兴趣的同学可以上去看看。
