python代码俄罗斯方块

以下是一个使用 Python 实现的简单俄罗斯方块代码示例。这个示例使用了 Pygame 库来创建游戏窗口和处理用户输入。

SCREEN_WIDTH = 640
SCREEN_HEIGHT = 480
BLOCK_SIZE = 20
BLOCK_COUNT_X = SCREEN_WIDTH // BLOCK_SIZE
BLOCK_COUNT_Y = SCREEN_HEIGHT // BLOCK_SIZE

# 颜色常量
COLOR_WHITE = (255, 255, 255)
COLOR_GRAY = (128, 128, 128)
COLOR_RED = (255, 0, 0)
COLOR_GREEN = (0, 255, 0)
COLOR_BLUE = (0, 0, 255)

# 方块形状定义
SHAPES = [
    [[1, 1, 1], [0, 1, 0]],
    [[2, 2, 0], [0, 2, 2]],
    [[3, 3], [3, 3]],
    [[0, 4, 4], [4, 4, 0]],
    [[5, 5, 5, 5]],
    [[6, 6, 6], [0, 0, 6]],
    [[7, 7, 7], [7, 0, 0]]

# 方块颜色定义

    COLOR_GRAY,
    COLOR_RED,
    COLOR_GREEN,
    COLOR_BLUE

这个示例实现了一个基本的俄罗斯方块游戏，包括方块的移动、旋转和碰撞检测等功能。注意，这个示例只是一个简单的实现，实际的游戏还需要更多的细节处理和优化。
