贪吃蛇用python实现用类
时间: 2023-09-27 10:04:28 浏览: 41
似乎您想问如何用 Python 实现贪吃蛇游戏,是吗?若是的话,可以使用 Pygame 模块来实现。可以定义一个“蛇”类,其中包括蛇的初始位置、长度、速度、方向等属性,还要有用于更新蛇位置、判断是否撞墙或自己、增加长度等方法。同时,还需要定义一个“食物”类,来控制食物的出现和消失。最后,将蛇和食物的显示和键盘事件绑定在一起即可。不过,如果您还有什么问题,尽管问我哦~

用Python实现贪吃蛇游戏
以下是用Python实现贪吃蛇游戏的一个简单示例:
```python
import pygame
import time
# 初始化游戏
pygame.init()
# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)

# 设置游戏窗口的宽度和高度
window_width = 800
window_height = 600
# 创建游戏窗口
game_window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption('贪吃蛇游戏')
# 设置游戏速度
clock = pygame.time.Clock()
snake_block_size = 20
snake_speed = 15
# 定义字体
font_style = pygame.font.SysFont(None, 50)
score_font = pygame.font.SysFont(None, 35)
# 定义显示分数的函数
def show_score(score):
score_text = score_font.render("Score: " + str(score), True, black)
game_window.blit(score_text, [10, 10])
# 定义绘制蛇的函数

for x in snake_list:
pygame.draw.rect(game_window, black, [x[0], x[1], snake_block_size, snake_block_size])
