俄罗斯方块游戏是一款经典的益智游戏，通常使用编程语言Python来实现。下面是一个简单的俄罗斯方块游戏的示例代码：
import pygameimport random# 定义颜色BLACK = (0, 0, 0)WHITE = (255, 255, 255)RED = (255, 0, 0)GREEN = (0, 255, 0)BLUE = (0, 0, 255)CYAN = (0, 255, 255)MAGENTA = (255, 0, 255)YELLOW = (255, 255, 0)ORANGE = (255, 165, 0)# 定义方块的形状SHAPES = [ [[1, 1, 1, 1]], [[1, 1], [1, 1]], [[1, 1, 0], [0, 1, 1]], [[0, 1, 1], [1, 1, 0]], [[1, 0, 0], [1, 1, 1]], [[0, 0, 1], [1, 1, 1]], [[1, 1, 1], [0, 1, 0]]]# 初始化游戏pygame.init()# 设置屏幕宽高SCREEN_WIDTH = 800SCREEN_HEIGHT = 600screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])pygame.display.set_caption("俄罗斯方块")# 定义方块的大小和间隙block_size = 30block_gap = 2# 初始化方块的位置x_pos = 3y_pos = 0# 初始化方块的形状shape = random.choice(SHAPES)# 初始化方块的颜色color = random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW, ORANGE])# 设置游戏时钟clock = pygame.time.Clock()# 判断方块是否可以移动def can_move(x_offset, y_offset): for i in range(len(shape)): for j in range(len(shape[i])): if shape[i][j]: x = x_pos + j + x_offset y = y_pos + i + y_offset if (x < 0 or x >= SCREEN_WIDTH // (block_size + block_gap) or y >= SCREEN_HEIGHT // (block_size + block_gap) or grid[y][x]): return False return True# 绘制方块def draw_block(x, y, color): pygame.draw.rect(screen, color, [(block_size + block_gap) * x, (block_size + block_gap) * y, block_size, block_size])# 绘制网格def draw_grid(grid): for i in range(len(grid)): for j in range(len(grid[i])): if grid[i][j]: draw_block(j, i, grid[i][j])# 更新网格def update_grid(x_offset, y_offset): global x_pos, y_pos x_pos += x_offset y_pos += y_offset for i in range(len(shape)): for j in range(len(shape[i])): if shape[i][j]: x = x_pos + j y = y_pos + i if y >= 0: grid[y][x] = color# 消除行def clear_rows(): full_rows = [] for i in range(len(grid)): if all(grid[i]): full_rows.append(i) for row in full_rows: del grid[row] grid.insert(0, [BLACK] * (SCREEN_WIDTH // (block_size + block_gap)))# 初始化网格grid = [[BLACK] * (SCREEN_WIDTH // (block_size + block_gap)) for _ in range(SCREEN_HEIGHT // (block_size + block_gap))]# 游戏主循环running = Truewhile running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False elif event.type == pygame.KEYDOWN: if event.key == pygame.K_LEFT and can_move(-1, 0): update_grid(-1, 0) elif event.key == pygame.K_RIGHT and can_move(1, 0): update_grid(1, 0) elif event.key == pygame.K_DOWN and can_move(0, 1): update_grid(0, 1) elif event.key == pygame.K_SPACE: rot_shape = list(zip(*reversed(shape))) if can_move(0, 0): shape = rot_shape elif can_move(-1, 0): update_grid(-1, 0) shape = rot_shape elif can_move(1, 0): update_grid(1, 0) shape = rot_shape if can_move(0, 1): update_grid(0, 1) else: clear_rows() x_pos = 3 y_pos = 0 shape = random.choice(SHAPES) color = random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW, ORANGE]) if not can_move(0, 1): running = False # 绘制背景 screen.fill(BLACK) # 绘制方块 for i in range(len(shape)): for j in range(len(shape[i])): if shape[i][j]: draw_block(x_pos + j, y_pos + i, color) # 绘制网格 draw_grid(grid) # 设置帧率 clock.tick(5) # 更新屏幕 pygame.display.flip()# 退出游戏pygame.quit()这段代码使用了Pygame库来实现游戏的图形界面，通过键盘控制方块的移动和旋转。游戏循环不断更新方块的位置和网格状态，并绘制在屏幕上。在方块达到底部或无法继续移动时，判断是否有满行，并清除满行的方块。游戏会根据方块的状态和移动情况不断更新，直到无法继续下落为止，游戏结束。
请注意，这只是一个简单的示例，可能还有一些功能和优化方面的改进。您可以根据自己的需求进行修改和扩展。
