Java 如何获得我的海龟图形海龟的 X 坐标

How do I get the X coordinate for my turtle graphics turtle

提问by user2779497

I can create a turtle that will be in a window with the following code:

我可以使用以下代码创建一个位于窗口中的海龟：

Turtle t1 = new Turtle(w,100,100);

If I want to know its coordinates, I can write:

如果我想知道它的坐标，我可以写：

int getX(w);

But when I have 2 turtles, t1 and t2, I don't know what to do if I want to know turtle1's X coordinates.

但是当我有2只海龟t1和t2时，如果我想知道turtle1的X坐标，我不知道该怎么办。

Turtle t1 = new Turtle(w,100,100);
Turtle t2 = new Turtle(w,200,100);

If I were to write int getX(w), which turtles X coordinate would I get? How do I write so I get t1s cordinate?

如果我写int getX(w)，我会得到哪些海龟的 X 坐标？我怎么写才能得到t1坐标？

I have no idea what Turtle class you are using, but I'd imagine you'd do something like this:

我不知道你在使用什么 Turtle 类，但我想你会做这样的事情：

int x1 = t1.getX(w);
int x2 = t2.getX(w);

For python turtle module, get the x and y coordinates of the turtle use the getPosition method like this:

对于 python 海龟模块，使用 getPosition 方法获取海龟的 x 和 y 坐标，如下所示：

import turtle
import time
alex = turtle.Turtle()
alex_text = turtle.Turtle()
alex_text.goto(alex.position()[0], alex.position()[1])
alex_text.write("hello")
time.sleep(1)

turtle.position() - Return the turtle's current location (x,y) (as a Vec2D vector).

turtle.position() - 返回海龟的当前位置 (x,y)（作为 Vec2D 向量）。

Use turtle.xcor()it returns the x position. Use turtle.ycor()it returns the y position.

使用turtle.xcor()它返回 x 位置。使用turtle.ycor()它返回 y 位置。
