俄罗斯方块
坐标的存储方式:
记录方式有两种:
1,横纵坐标做一个二元元组,再用一个列表装着一堆二元元组
例如:[(20,1),(20,2),(20,3),(20,4)]代表第20行的1~4列的四个方块
2,二维数组,一行是一个列表,用两个索引代表横纵坐标,值为1就代表有方块,0就是没有方块
例如:block[20][1] 值为1就表示20行第1列有方块,block[20][5] 为0表示20行第5列有没有方块
键盘到图像(本质:键盘到核心变量)
下面简略列出需要的函数
名称 内容 发生时机
左右移动 修改y轴坐标 键盘事件
旋转 复杂的坐标转化 键盘事件
下落 修改x轴坐标 键盘事件,计时器
下落检查 检查是否可以继续下落 下落前后
检查方块 逐行检查是否可以消除, 下落检察后
消除方块 检查方块后
生成方块 产生下一个方块 消除方块后
检查存活
生成的方块 无法放置<=>堆到顶端<=>game over堆到顶端<=>game over
