俄罗斯方块是一款经典的益智游戏,它的源码可以通过多种编程语言实现。以下是一个简单的Python实现:,,“python,import pygame,import sys,import random,,pygame.init(),,# 设置屏幕大小,screen = pygame.display.set_mode((800, 600)),,# 设置颜色,WHITE = (255, 255, 255),BLACK = (0, 0, 0),,# 设置字体,font = pygame.font.Font(None, 36),,# 定义方块形状,shapes = [, [[‘…..’,, ‘…..’,, ‘..O..’,, ‘.OOO.’,, ‘…..’],, [‘…..’,, ‘..O..’,, ‘..OO.’,, ‘…O.’,, ‘…..’],, [‘…..’,, ‘…..’,, ‘.OOO.’,, ‘..O..’,, ‘…..’],, [‘…..’,, ‘..O..’,, ‘.OO..’,, ‘..O..’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘.OOO.’,, ‘.O…’,, ‘…..’],, [‘…..’,, ‘.OO..’,, ‘..O..’,, ‘..O..’,, ‘…..’],, [‘…..’,, ‘…O.’,, ‘.OOO.’,, ‘…..’,, ‘…..’],, [‘…..’,, ‘.O…’,, ‘.OO..’,, ‘.O…’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘.OOO.’,, ‘…O.’,, ‘…..’],, [‘…..’,, ‘..O..’,, ‘..O..’,, ‘.OO..’,, ‘…..’],, [‘…..’,, ‘.O…’,, ‘.OOO.’,, ‘…..’,, ‘…..’],, [‘…..’,, ‘.OO..’,, ‘.O…’,, ‘.O…’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘.OO..’,, ‘.OO..’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘..OO.’,, ‘.OO..’,, ‘…..’],, [‘…..’,, ‘..O..’,, ‘.OO..’,, ‘…O.’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘.OO..’,, ‘..OO.’,, ‘…..’],, [‘…..’,, ‘…O.’,, ‘.OOO.’,, ‘…..’,, ‘…..’]],, [[‘…..’,, ‘…..’,, ‘…O.’,, ‘.OOO.’,, ‘…..’],, [‘…..’,, ‘.OO..’,, ‘.O…’,, ‘.O…’,, ‘…..’]],,],,def create_grid(locked_positions={}):, grid = [[(0, 0, 0) for _ in range(10)] for _ in range(20)],, for y in range(len(grid)):, for x in range(len(grid[y])):, if (x, y) in locked_positions:, grid[y][x] = locked_positions[(x, y)],, return grid,,def check_collision(grid, pos, shape):, for px, py in shape:, try:, grid_x, grid_y = pos[0] + px, pos[1] + py, if grid_x 9 or grid_y 19:, return True, if grid[grid_y][grid_x] != (0, 0, 0):, return True, except IndexError:, return True, return False,,def merge(grid, pos, shape):, for px, py in shape:, grid_x, grid_y = pos[0] + px, pos[1] + py, grid[grid_y][grid_x] = shape[px][py],,def draw_grid(surface, grid):, for y in range(len(grid)):, for x in range(len(grid[y])):, pygame.draw.rect(surface, grid[y][x], (x * 30, y * 30, 29, 29), 0), pygame.draw.rect(surface, (0, 0, 0), (x * 30, y * 30, 29, 29), 1),,def draw_window(surface, grid):, surface.fill((0, 0, 0)), draw_grid(surface, grid), pygame.display.update(),,def main():, locked_positions = {}, grid = create_grid(locked_positions), change_piece = False, run = True, current_piece = random.choice(shapes), current_pos = [0, 0], timer = pygame.time.Clock(), fall_time = 0, level_time = 0, level = 1, fall_speed = level / 500 + 1,, while run:, grid = create_grid(locked_positions), fall_time += timer.get_rawtime(), level_time += timer.get_rawtime(), timer.tick(),, if level_time / 1000 ˃ 5:, level_time = 0, if level fall_speed:, fall_time = 0, current_piece, current_pos = next_piece(current_piece, current_pos, grid, locked_positions), if not check_collision(grid, current_pos, current_piece):, change_piece = True, else:, for px, py in current_piece:, grid[current_pos[1] + py][current_pos[0] + px] = (0, 0, 0), current_piece = random.choice(shapes), current_pos = [0, 0], change_piece = False, if check_collision(grid, current_pos, current_piece):, run = False, draw_window(screen, grid), pygame.display.update(),“
