[Unity3D+演算法]一小時做個2048

2048是繼FlappyBird之後另一個比較熱的輕量級的手遊，簡單易玩。最近要離職原先的公司——因為我想做遊戲，雖然玩遊戲不是很多，但還是熱愛開發遊戲，因此就想去一家遊戲公司，感覺對老闆有一點愧疚和感激，願原公司發展越來越好，用灰太狼的話講，我還會回來的，哈哈！即將入職新公司，聽說壓力會很大，加班無止境，加班其實我到不怕，乘年輕，還有拼勁，加班算什麼，其實只要自己能做出東西，感覺有成就感，倒還是喜歡花更多的時間去做東西，最近處於過渡期，寫寫之前公司的工作小結，還不是很忙，今天花了一個多小時，自己想了一下2048的演算法，然後將其實現，可能演算法不是那麼優，還望批評交流！

實現的還比較粗糙，貼出主要邏輯代碼，僅供參考，歡迎給出更優演算法！
