本文分享的這些俄羅斯方塊代碼是我最近放假在家里自己寫的，雖然以前有過看別人寫的代碼，但是那個游戲代碼好像不是很全面，因為無法實現全部的方塊和實現隨機的產生任意方向的方塊，現在也基本上是忘光了當時的代碼，下面的這些代碼是我最近寫的，沒有參考其他人的代碼，真正寫俄羅斯方塊起來感覺真的是挺難的，關鍵是在于方塊的旋轉。當然下面的代碼僅僅是一個框架，只能夠實現大致上的功能，還不全面，貼出來和大家交流學習。
編譯器是code：：block + MinGW ，感覺CB這個IDE真的是太強大，太棒了，下面的代碼直接復制到VC里面運行應該不會出錯，有個問題一直不知道怎么解決，就是更新客戶區時窗口總是閃不知道有哪位達人能指點我一下。有的都是windows API寫的，對windows編程還不是很懂，望大家多多留言，指點一下本人。
