python贪吃蛇编程代码

当编写贪吃蛇游戏的 Python 代码时，你可以使用 Pygame 等库来实现图形界面和游戏逻辑。

python
import pygame
import time
import random
pygame.init()
# 定义颜色
white = (255, 255, 255)
yellow = (255, 255, 102)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)
# 设置屏幕大小
dis_width = 600
dis_height = 400
dis = pygame.display.set_mode((dis_width, dis_height))
pygame.display.set_caption('贪吃蛇游戏')
# 设置游戏参数
snake_block = 10
snake_speed = 15
# 定义字体
font_style = pygame.font.SysFont(None, 50)
# 定义蛇
snake = [[dis_width // 2, dis_height // 2]]
snake_direction = 'RIGHT'
change_to = snake_direction
# 定义食物位置
foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0
foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0
# 定义分数
score = 0
# 定义函数
def our_snake(snake_block, snake_list):
for x in snake_list:
pygame.draw.rect(dis, white, [x[0], x[1], snake_block, snake_block])
def message(msg, color):
mesg = font_style.render(msg, True, color)
dis.blit(mesg, [dis_width / 6, dis_height / 3])
# 游戏主循环
game_over = False
while not game_over:
for event in pygame.event.get():
if event.type == pygame.QUIT:
game_over = True
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_UP and not snake_direction == 'DOWN':
change_to = 'UP'
elif event.key == pygame.K_DOWN and not snake_direction == 'UP':
change_to = 'DOWN'
elif event.key == pygame.K_LEFT and not snake_direction == 'RIGHT':
change_to = 'LEFT'
elif event.key == pygame.K_RIGHT and not snake_direction == 'LEFT':
change_to = 'RIGHT'
# 更新蛇的方向
if change_to == 'UP' and not snake_direction == 'DOWN':
snake_direction = 'UP'
elif change_to == 'DOWN' and not snake_direction == 'UP':
snake_direction = 'DOWN'
elif change_to == 'LEFT' and not snake_direction == 'RIGHT':
snake_direction = 'LEFT'
elif change_to == 'RIGHT' and not snake_direction == 'LEFT':
snake_direction = 'RIGHT'
# 移动蛇的头部
if snake_direction == 'UP':
snake[0][1] -= snake_block
elif snake_direction == 'DOWN':
snake[0][1] += snake_block
elif snake_direction == 'LEFT':
snake[0][0] -= snake_block
elif snake_direction == 'RIGHT':
snake[0][0] += snake_block
# 判断是否吃到食物
if snake[0][0] == foodx and snake[0][1] == foody:
foodx = round(random.randrange(0, dis_width - snake_block) / 10.0) * 10.0
foody = round(random.randrange(0, dis_height - snake_block) / 10.0) * 10.0
score += 1
else:
snake.pop()
# 判断是否碰到边界或自身
if (
snake[0][0] < 0
or snake[0][0] >= dis_width
or snake[0][1] < 0
or snake[0][1] >= dis_height
):
game_over = True
for block in snake[1:]:
if block == snake[0]:
game_over = True
# 更新屏幕
dis.fill(black)
pygame.draw.rect(dis, blue, [foodx, foody, snake_block, snake_block])
our_snake(snake_block, snake)
# 显示分数
score_font = pygame.font.SysFont(None, 35)
value = score_font.render("Score: " + str(score), True, white)
dis.blit(value, [0, 0])
pygame.display.update()
# 控制游戏速度
pygame.time.Clock().tick(snake_speed)
# 游戏结束时显示消息
message("你输了！", red)
pygame.display.update()
time.sleep(2)
pygame.quit()
quit()

请确保你已安装 Pygame 库，你可以使用

bash
pip install pygame

此代码实现了一个简单的贪吃蛇游戏，你可以根据需要进行修改和扩展。

python
# 在之前的代码后面添加
