引入库

import copyimport randomimport sysimport pygame

初始化模型

# 蛇模型snake_list = [[10, 10]]# 食物的模型x = random.randint(10, 490)y = random.randint(10, 490)food_point = [x, y]food_r, food_g, food_b = random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)food_color = pygame.Color(food_r, food_g, food_b)# 初始方向move_up = Falsemove_down = Falsemove_left = Falsemove_right = True# 初始分数score=0pygame.init()screen = pygame.display.set_mode((500, 500))# 画布大小title = pygame.display.set_caption('贪吃蛇')# 名字clock = pygame.time.Clock() # 游戏时钟

获取键盘事件

for event in pygame.event.get():# 获取键盘事件if event.type == pygame.QUIT:running=Falsesys.exit()if event.type == pygame.KEYDOWN:if event.key == pygame.K_DOWN or event.key == pygame.K_s:move_up = Falsemove_down = Truemove_left = Falsemove_right = Falseif event.key == pygame.K_UP or event.key == pygame.K_w:move_up = Truemove_down = Falsemove_left = Falsemove_right = Falseif event.key == pygame.K_LEFT or event.key == pygame.K_a:move_up = Falsemove_down = Falsemove_left = Truemove_right = Falseif event.key == pygame.K_RIGHT or event.key == pygame.K_d:move_up = Falsemove_down = Falsemove_left = Falsemove_right = Trueif event.key == pygame.K_ESCAPE:# esc关闭running=Falsesys.exit()if event.key ==pygame.K_SPACE and not running:running=Truesnake_list = [[10, 10]]score=0

移动贪吃蛇

# 身子移动snake_len = len(snake_list) - 1while snake_len > 0:snake_list[snake_len] = copy.deepcopy(snake_list[snake_len - 1])snake_len -= 1# 蛇头移动if move_up:snake_list[snake_len][1] -= 10if snake_list[snake_len][1] < 0:snake_list[snake_len][1] = 500if move_down:snake_list[snake_len][1] += 10if snake_list[snake_len][1] > 500:snake_list[snake_len][1] = 0if move_left:snake_list[snake_len][0] -= 10if snake_list[snake_len][0] < 0:snake_list[snake_len][0] = 500if move_right:snake_list[snake_len][0] += 10if snake_list[snake_len][0] > 500:snake_list[snake_len][0] = 0

吃食物逻辑

# 蛇与食物碰撞检测if food_rect.collidepoint(snake_pos):snake_list.append(food_point)food_point = [random.randint(10, 490), random.randint(10, 490)] # 重新生成食物food_r, food_g, food_b = random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)food_color = pygame.Color(food_r, food_g, food_b)score+=1break

碰撞到自身逻辑

# 吃到自己结束游戏snake_head_rect = snake_rect[0] # 蛇头count = len(snake_rect)while count > 1: if snake_head_rect.colliderect(snake_rect[count - 1]): # 检测蛇头与身子的所有点running=False count -= 1

结束游戏

if not running:show_text(screen, (20,200), 'GAME OVER!', (227, 29, 18), False, 100)show_text(screen, (120,300), 'press space to try again', (223, 223, 223), False, 30)

显示文字函数
