[Unity3D+算法]一小时做个2048

太阳不下山

2048是继FlappyBird之后另一个比较热的轻量级的手游，简单易玩。最近要离职原先的公司——因为我想做游戏，虽然玩游戏不是很多，但还是热爱开发游戏，因此就想去一家游戏公司，感觉对老板有一点愧疚和感激，愿原公司发展越来越好，用灰太狼的话讲，我还会回来的，哈哈！即将入职新公司，听说压力会很大，加班无止境，加班其实我到不怕，乘年轻，还有拼劲，加班算什么，其实只要自己能做出东西，感觉有成就感，倒还是喜欢花更多的时间去做东西，最近处于过渡期，写写之前公司的工作小结，还不是很忙，今天花了一个多小时，自己想了一下2048的算法，然后将其实现，可能算法不是那么优，还望批评交流！
效果图

实现的还比较粗糙，贴出主要逻辑代码，仅供参考，欢迎给出更优算法！
