这篇教程Python贪吃蛇小游戏实例分享写得很实用，希望能帮到您。
本文实例为大家分享了Python实现贪吃蛇小游戏的具体代码，供大家参考，具体内容如下 使用的库pygame 、random 、pyautogui 流程简述1.设置初始参数 设置每个网格大小为 20 px ，size可以随意修改但最好为20的倍数，设置初始方向向右，初始蛇长为 3 。 # 初始化参数size = 320screen = pygame.display.set_mode([size,size],0 , 32)pygame.display.set_caption("贪吃蛇")cell_size = 20cell_num = int(size/20)x , y = [60,0]# 初始方向向右dir_snake = 'R'body_snake = [[0,0],[20,0],[40,0],[60,0]]# 初始蛇长为3len_snake = 3# 初始食物坐标food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20]# 蛇移动速度clock = pygame.time.Clock()2.键盘控制 键盘上下左右控制蛇方向，禁止反向。 3.食物 蛇头吃到食物后，蛇长加一 ，random 一个随机坐标，如果坐标再蛇身上则继续 random。 if [x,y] == food_coor[:2]: food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20] if food_coor[:2] in body_snake[-2:-len_snake -1 :-1]: food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20] len_snake +=1 4. 胜负判断 蛇头与蛇身碰撞判输，弹出游戏结束窗口，说明最终蛇长为多长。 if body_snake[-1] in body_snake[-2:-len_snake -1 :-1]: pyautogui.alert(text='游戏结束,最终蛇长为{}'.format(len_snake)) exit()代码及结果代码 import pygame , random ,pyautoguifrom pygame.locals import *# 初始化参数size = 500screen = pygame.display.set_mode([size,size],0 , 32)pygame.display.set_caption("贪吃蛇")cell_size = 20cell_num = int(size/20)x , y = [60,0]# 初始方向向右dir_snake = 'R'body_snake = [[0,0],[20,0],[40,0],[60,0]]# 初始蛇长为3len_snake = 3# 初始食物坐标food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20]# 蛇移动速度clock = pygame.time.Clock()# bgdef bg(): for i in range(0, size , int(cell_size)): pygame.draw.line(screen,[72,72,72],[i,0],[i,size]) for i in range(0, size, int(cell_size)): pygame.draw.line(screen, [72, 72, 72], [0, i], [size,i])# 蛇def snake(K): for x,y in K[:-len_snake - 1:-1]: pygame.draw.rect(screen,[255,255,255],[x,y,20,20],0)# 食物def food(): pygame.draw.rect(screen,[255,0,0],food_coor,0)# 主循环def running(): global x ,y , dir_snake ,food_coor , len_snake while True: for event in pygame.event.get(): if event.type == QUIT: exit() screen.fill((40, 43, 46)) # 方向规则 if dir_snake == 'U': y -= 20 elif dir_snake == 'R': x += 20 elif dir_snake == 'D': y += 20 elif dir_snake == 'L': x -= 20 # 键盘方向控制 if event.type == KEYDOWN: if event.key == K_LEFT and dir_snake != 'R': dir_snake = 'L' elif event.key == K_DOWN and dir_snake != 'U': dir_snake = 'D' elif event.key == K_RIGHT and dir_snake != 'L': dir_snake = 'R' elif event.key == K_UP and dir_snake != 'D': dir_snake = 'U' # 撞墙之后 if x < 0: x += size elif x >= size: x -= size elif y < 0: y += size elif y >= size: y -= size # draw蛇体 body_snake.append([x,y]) snake(body_snake) food() # 吃到食物后food换位置 if [x,y] == food_coor[:2]: food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20] if food_coor[:2] in body_snake[-2:-len_snake -1 :-1]: food_coor = [random.randint(0, cell_num - 1) * 20, random.randint(0, cell_num - 1) * 20, 20, 20] len_snake +=1 # 游戏结束 if body_snake[-1] in body_snake[-2:-len_snake -1 :-1]: pyautogui.alert(text='游戏结束,最终蛇长为{}'.format(len_snake)) exit() # 格线 bg() # 右下角显示蛇长 font = pygame.font.SysFont("simsunnsimsun", 40) text_surface = font.render("{}".format(len_snake), True, (255,255, 255)) screen.blit(text_surface , (size-40,size-40)) pygame.display.update() # 蛇的移动速度随着蛇的长度而越来越快 clock.tick(len_snake * 2)if __name__ == '__main__': pygame.init() running()输出结果
