贪吃蛇小游戏的简单源代码
贪吃蛇小游戏源码主要包括以下几个部分：1. 初始化游戏界面，设置蛇的初始位置和食物的位置；2. 监听用户输入，控制蛇的移动方向；3. 更新蛇的位置，判断是否吃到食物；4. 判断蛇是否撞到墙壁或自己，如果撞到则游戏结束；5. 更新游戏界面，显示蛇和食物的位置。以下是一个简单的贪吃蛇小游戏源码示例： ```python import pygame import sys import random pygame.init() # 设置窗口大小和标题 screen = pygame.display.set_mode((640, 480)) pygame.display.set_caption("贪吃蛇") # 初始化蛇和食物的位置 snake_pos = [[100, 100], [90, 100], [80, 100]] food
