随机海龟移动，绑定 window

Question

创建了使乌龟移动随机化的程序，但无法让它在触及边界后打破循环 (window)。尝试了一些类似问题的解决方案，但仍然没有成功。

from turtle import Turtle, Screen
import random

def createTurtle(color, width):
    tempName = Turtle("turtle")
    tempName.speed("fastest")
    tempName.color(color)
    tempName.width(width)
    return tempName

def inScreen(screen, turt):

    min_x, max_x = -wn.window_width() / 2 , wn.window_width() / 2
    min_y, max_y = -wn.window_height() / 2 , wn.window_height() / 2

    turtleX, turtleY = turt.pos()

    while (min_x < turtleX < max_x) and (min_y < turtleY < max_y):
        turt.left(random.randrange(360))
        turt.fd(random.randrange(100))
        turtleX, turtleY = turt.pos()
        print(turtleX, ",", turtleY)


wn = Screen()

alpha = createTurtle("red", 3)

inScreen(wn, alpha)

wn.exitonclick()

Answer 1

在您的 while 条件中使用了变量 turtleX 和 turtleY，但您从未在循环中重新计算它们。

这就是为什么你的打印函数只输出 0.0 , 0.0
