这些游戏你玩过几个？
1.贪吃蛇
👉游戏规则：使用方向键控制蛇去吃球。每吃一次球，蛇身就长出一格。吃到自己或者出界游戏结束。
from random import randrange
from turtle import *
from freegames import square, vector
food = vector(0, 0)
snake = [vector(10, 0)]
aim = vector(0, -10)
def change(x, y):
"""Change snake direction."""
aim.x = x
aim.y = y
def inside(head):
"""Return True if head inside boundaries."""
return -200 < head.x < 190 and -200 < head.y < 190
def move():
"""Move snake forward one segment."""
head = snake[-1].copy()
head.move(aim)
if not inside(head) or head in snake:
square(head.x, head.y, 9, 'red')
update()
return
snake.append(head)
if head == food:
print('Snake:', len(snake))
food.x = randrange(-15, 15) * 10
food.y = randrange(-15, 15) * 10
else:
snake.pop(0)
clear()
for body in snake:
square(body.x, body.y, 9, 'black')
square(food.x, food.y, 9, 'green')
update()
ontimer(move, 100)
setup(420, 420, 370, 0)
hideturtle()
tracer(False)
listen()
onkey(lambda: change(10, 0), 'Right')
onkey(lambda: change(-10, 0), 'Left')
onkey(lambda: change(0, 10), 'Up')
onkey(lambda: change(0, -10), 'Down')
move()
done()
游戏演示：
2.吃豆人
👉游戏规则：用箭头导航控制黄色吃豆人吃掉所有白色食物，若被红色的鬼魂抓住，游戏结束。
