python小游戏俄罗斯方块源代码pygame

以下是使用 Pygame 实现俄罗斯方块的简单源代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 游戏区域的宽度和高度
WINDOW_WIDTH = 600
WINDOW_HEIGHT = 800

# 方块的大小
BLOCK_SIZE = 40

# 游戏区域的宽度和高度按照方块大小计算
GAME_WIDTH = WINDOW_WIDTH // BLOCK_SIZE
GAME_HEIGHT = WINDOW_HEIGHT // BLOCK_SIZE

# 方块的颜色
BLOCK_COLORS = [
    (255, 0, 0),    # 红色
    (0, 255, 0),    # 绿色
    (0, 0, 255),    # 蓝色
    (255, 255, 0),  # 黄色
    (255, 0, 255),  # 紫色
    (0, 255, 255),  # 青色
    (255, 255, 255) # 白色
]

# 7 种不同的方块形状
BLOCK_SHAPES = [
    [[1, 1, 1, 1]],                        # I 形状
    [[1, 1, 1], [0, 1, 0]],                # T 形状
    [[1, 1, 0], [0, 1, 1]],                # Z 形状
    [[0, 1, 1], [1, 1, 0]],                # S 形状

这个源代码可能不是最完整最标准的版本，但足以说明 Pygame 如何实现俄罗斯方块游戏。
