俄罗斯方块

本文主要是介绍俄罗斯方块,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

俄罗斯方块

  • 方块程序编写了各种方块,由于我很菜,于是自己添加了几个方块来是游戏更简单。
import random
from collections import namedtuple

Point = namedtuple('Point', 'X Y')
Shape = namedtuple('Shape', 'X Y Width Height')
Block = namedtuple('Block', 'template start_pos end_pos name next')

# 方块形状的设计,我最初我是做成 4 × 4,因为长宽最长都是4,这样旋转的时候就不考虑怎么转了,就是从一个图形替换成另一个
# 其实要实现这个功能,只需要固定左上角的坐标就可以了

# S形方块
S_BLOCK = [Block(['.OO',
                  'OO.',
                  '...'], Point(0, 0), Point(2, 1), 'S', 1),
           Block(['O..',
                  'OO.',
                  '.O.'], Point(0, 0), Point(1, 2), 'S', 0)]
