[Ling soul GPL]

对于俄罗斯方块相信我们大家再也熟悉不过。那么下面我为大家带来本人亲自获得市区三等奖的代码分享给大家。 先上个图 # coding : utf-8 #: pip install pygame import random import sys import pygame #: 颜色定义 COLOR_WHITE = (255, 255, 255) COLOR_BLACK = (0, 0, 0) class Block: """小块""" width = 24 height = 24 @staticmethod def draw(s, left, top, color, bg_color): pygame.draw.rect(s, bg_color, pygame.Rect(left, top, Block.width, Block.height)) pygame.draw.rect(s, color, pygame.Rect(left, top, Block.width - 1, Block.height - 1)) class Building: """积木""" def __init__(self): """ 方块的7种基本形状 每次初始化随机选择一个形状 @:return True / False """ self.form = random.choice( [ [ [0, 0, 0, 0, 0], [0, 0, 1, 0, 0], [0, 1, 1, 1, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [1, 1, 1, 1, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 1, 1, 0, 0], [0, 0, 1, 1, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 0, 1, 1, 0], [0, 1, 1, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 1, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 0, 1, 1, 0], [0, 0, 1, 0, 0], [0, 0, 1, 0, 0], [0, 0, 0, 0, 0] ], [ [0, 0, 0, 0, 0], [0, 1, 1, 0, 0], [0, 1, 1, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ] ]) def __getitem__(self, pos): return self.form[pos] def __setitem__(self, key, value): self.form[key] = value class Layout: """棋盘""" def __init__(self): self.block_x_count = 16; self.block_y_count = 22; self.layout = [[0 if 1 < i < self.block_x_count - 2 and j < self.block_y_count - 2 else 1 for i in range(self.block_x_count)] for j in range(self.block_y_count)] @property def size(self): """返回棋盘屏幕大小(width,height)""" return (self.block_x_count * Block.width, self.block_y_count * Block.height) def create_new_building(self): """ 创建新的积木,初始化位置为第5,0格, 速度为4 :return: 返回是否无空间创建了 """ self.building = Building() self.building_left, self.building_top = 5, 0 # self.drop_speed = 3 print(self.test_building_touch_wall()) return self.test_building_touch_wall() @property def speed(self): return self.drop_speed def test_building_touch_wall(self, x_offset=0, y_offset=0): """ 积木是否已经触底/墙壁 具体操作： 判断积木最后一排的1，是否在当前棋牌对应的位置是也是1 @:param x_offset: x的偏移量 移动时可以传入1/-1来判断 @:param y_offset: y的偏移量 正常下落时可以传入1来判断 """ for i in range(4, -1, -1): for j in range(5): if self.building[i][j]: if self.layout[i + self.building_top + y_offset][j + self.building_left + x_offset]: return True return False def move_left_right(self, x): """ 左右移动 @:param x: 移动量 x_offset """ #: 移动时不能撞墙 if not self.test_building_touch_wall(x_offset=x): self.building_left += x def down_build(self): """ 盒子的自动下移 """ self.building_top += 1 def direct_down(self): """ 手动快速降落 """ self.drop_speed = 50 def convert_building(self): """ * 扭转盒子的总方位 (右转) 具体操作： 把第一竖排的倒序给第一横排的 把第二竖排的倒序给第二横排的 后面同理.
