2048 控制臺(tái)版(C#)

2048游戲現(xiàn)在很火啊，很多人應(yīng)該已經(jīng)玩過(guò)了。在博客園上也看見(jiàn)有人模仿做的GDI+版 2048游戲，鄙人暫且不做那么多動(dòng)畫(huà)的東西，畢竟是個(gè)小東東，在此奉上一個(gè)《控制臺(tái)版2048》。

Main 方法程序入口，RePaint 類似Win32程序中的刷新界面，SquareRot90 矩形矩陣順時(shí)針旋轉(zhuǎn)90度角（參數(shù)可以為負(fù)，表示逆時(shí)針）。Merge 向左移動(dòng)，合并單元格中值相同的元素，并進(jìn)行整理（將所有元素靠左放置）RandomPoint 隨機(jī)生成點(diǎn)，從矩陣的空位置（值為0）中隨機(jī)生成一個(gè)點(diǎn)，若不存在空位置返回null。CanMove 判斷是否可以繼續(xù)移動(dòng)，也是判斷游戲是否結(jié)束的方法。IsEquals 判斷兩矩陣的值是否相同。CopyToB 將矩陣復(fù)制一份。
