龟窗挂
龟窗挂
提问于 2021-03-16 15:17:42
当我试图运行我的代码时，我的python海龟窗口就会挂起；我也不能移动。我尝试过移除win_pen，但我不知道win_pen内部是什么使它挂起的。
它也给了我纺车，因为我是在Mac，我不确定这是否是问题的这一点。顺便说一下，我在大苏尔11.1号上。

代码有几个问题:不要在像海龟这样的事件驱动的世界中使用while True: --让事件处理程序来完成它的工作；您的碰撞逻辑是不正确的，因为它从海龟的中心测量，而我们实际上只关注两只海龟的y位置；您似乎在错误的方向重置玩家；您两次实现获胜区域。
我重写并简化了下面包含上述更改和其他一些调整的代码：
from turtle import Screen, Turtle

PLAYER_SPEED = 15
def left():
player.setheading(180)
player.setx(max(-280, player.xcor() - PLAYER_SPEED))
check_collision(player, win_pen)
def right():
player.setheading(0)
player.setx(min(280, player.xcor() + PLAYER_SPEED))
check_collision(player, win_pen)
def up():
player.setheading(90)
player.sety(min(280, player.ycor() + PLAYER_SPEED))
check_collision(player, win_pen)
def down():
player.setheading(270)
player.sety(max(-280, player.ycor() - PLAYER_SPEED))
check_collision(player, win_pen)
def check_collision(player, win_pen):
if abs(player.ycor() - win_pen.ycor()) < 15:
player.sety(-250)
player.setheading(90)
