[Unity3D+算法]一小时做个2048

[Unity3D+算法]一小时做个2048

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!

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!
