贪吃蛇游戏项目说明
项目简介
这是一个使用Python和Pygame库开发的简单贪吃蛇游戏。在游戏中,玩家控制一条蛇在屏幕上移动,蛇的目标是吃到随机出现的食物。每吃到一个食物,蛇的长度会增加,同时游戏速度也会逐渐加快。玩家需要避免蛇碰到屏幕边界或自身,否则游戏结束。
项目依赖
- Python 3.x
- Pygame 库
安装依赖
在运行游戏之前,请确保已安装Pygame库。如果未安装,可以使用以下命令进行安装:
sh
pip install pygame
python
import pygame
import time
import random
# 初始化Pygame
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)
# 显示窗口大小
display_width = 800
display_height = 600
# 创建显示窗口
display = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption('贪吃蛇游戏')
# 定义时钟
clock = pygame.time.Clock()
# 设置贪吃蛇大小和速度
snake_block = 10
snake_speed = 15
# 字体样式
font_style = pygame.font.SysFont("bahnschrift", 25)

clock.tick(snake_speed)
pygame.quit()
quit()
gameLoop()
游戏控制:使用键盘上的方向键(上、下、左、右)控制贪吃蛇的移动。
食物生成:食物在屏幕上的随机位置生成,贪吃蛇吃到食物后会变长,并生成新的食物。
游戏结束条件:贪吃蛇碰到屏幕边界或自身,游戏结束,并显示游戏结束提示信息。
游戏重新开始:游戏结束后,可以按"C"键重新开始游戏,按"Q"键退出游戏。
效果如下:
