C++制作俄羅斯方塊

更新時間：2016年05月08日 14:53:31 作者：maxuewei2

俄羅斯方塊寫過好幾次了，每次的感覺都不一樣，都有新的收獲。就像達(dá)芬奇畫雞蛋一樣，雖然都是畫同樣的雞蛋，但是每次都有不同的收獲。 

緣起：

　　在玩Codeblocks自帶的俄羅斯方塊時覺得不錯，然而有時間限制。所以想自己再寫一個。

程序效果：

主要內(nèi)容：

　　程序中有一個board數(shù)組，其中有要顯示的部分，也有不顯示的部分，不顯示的部分都存儲1。

　　如下圖：

　　shape采用4*4數(shù)組(shape)保存。如：

　　　　0 0 0 0
　　　　0 1 0 0
　　　　1 1 1 0
　　　　0 0 0 0

　　另外用變量row和column保存shape數(shù)組左上角在board中的位置。

　　每次下落或左右移動，先對row和column做出改變，然后檢測當(dāng)前row和column下，shape是否重合了為1的格子，如果有重合，就說明shape出界了或者到達(dá)下落最低點(diǎn)，則要恢復(fù)row和column值。另外，如果是下落，還要將shape放在board上，并產(chǎn)生新的shape。

　　旋轉(zhuǎn)時，先對shape數(shù)組進(jìn)行旋轉(zhuǎn)操作，然后檢測重合，如果有重合，則反向旋轉(zhuǎn)回來。
