1.简介
使用了turtle库来创建图形界面,你可以使用键盘的W、A、S、D键来控制蛇的移动方向。蛇吃到食物后,身体会增长,如果蛇撞到自己或者游戏边界,游戏就会结束。
2. 代码
import turtle
import time
import random
delay = 0.1
# 生成食物的位置
food = turtle.Turtle()
food.shape("circle")
food.color("red")
food.penup()
food.goto(random.randint(-15, 15), random.randint(-15, 15))
food.speed(0)
# 蛇头
head = turtle.Turtle()
head.shape("square")
head.color("blue")
head.penup()
head.goto(0, 0)
head.direction = "stop"
# 蛇的食物
segments = []
# 用于控制蛇的移动
