方块的类型方块的变形方块的消除方块的存储方块的移动接受用户的输入
2. 概要设计
2.1 方块类型与变形
一共有七种#xff0c;变换的方式如下。变换后的任意形状方块实际上可以存在一个4x4的矩阵中。 我们再压一下位#xff0c;就可以存在16位中。

2. 概要设计
2.1 方块类型与变形
一共有七种变换的方式如下。变换后的任意形状方块实际上可以存在一个4x4的矩阵中。 我们再压一下位就可以存在16位中。
2.2 方块的消除
只需要检查一整行全部都是方块即可。
2.3 方块的移动
详见tinytetris
使用一个简单的循环计时来实现(do_ticks())。
2.4 接受用户输入
直接使用ncurse中的getch即可获得键盘、鼠标等输入。
