我正在用Python 3.6.4开发游戏。

当玩家触摸红色圆圈时,玩家应该传送回起点。

问题1:如果乌龟撞到红色圆圈,如何将其移动到起点?

我的代码:

import turtle

wn = turtle.Screen()
wn.bgcolor("black")

player = turtle.Turtle()
player.color("white")
player.speed(0)
player.penup()
player.setposition(100, -110)

enemy = turtle.Turtle()
enemy.color("red")
enemy.shape("circle")
enemy.penup()
enemy.setposition(100, -100)

if player.pos(100, -100):
    player.pos(100, -110)


我得到的错误是:

Traceback (most recent call last): File "C:\Users\ruffi\AppData\Local\Programs\Python\Python36-32\behg.p", line 18, in <module> if player.pos(100, -100):TypeError: pos() takes 1 positional argument but 3 were given

问题2:如何解决此错误?

最佳答案

我要解决这两个问题的方法是不要自己比较位置,而是使用turtle提供的distance()方法:

if player.distance(enemy) < 10:  # if the centers are within 10 pixels


这是一个完整的示例,可让您单击屏幕来移动玩家,但如果玩家离敌人的心太近,它将传送回到起点,您可以通过单击屏幕再次移动:

from turtle import Turtle, Screen

wn = Screen()
wn.setup(500, 500)
wn.bgcolor('black')

player = Turtle(visible=False)
player.speed('fastest')
player.shapesize(2)
player.color('white')
player.penup()
player.setposition(200, -200)
player.showturtle()

enemy = Turtle('circle', visible=False)
enemy.shapesize(2)
enemy.color('red')
enemy.penup()
enemy.setposition(-200, 200)
enemy.showturtle()

def click_handler(x, y):
    wn.onclick(None)  # disable handler while in handler
    player.setheading(player.towards(x, y))  # head towards new location
    player.setposition(x, y)

    if player.distance(enemy) < 10:
        player.hideturtle()  # teleport
        player.setposition(200, -200)
        player.showturtle()

    wn.onclick(click_handler)

wn.onclick(click_handler)

wn.mainloop()
