tkinter와 turtle 동시에 사용하기

기본 예제

import turtle
import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(master=root, width=500, height=500)
canvas.pack()

t = turtle.RawTurtle(canvas)

tk.Button(master=root, text="Forward", command=lambda: t.forward(100)).pack(side=tk.TOP)
tk.Button(master=root, text="Back", command=lambda: t.back(100)).pack(side=tk.BOTTOM)
tk.Button(master=root, text="Left", command=lambda: t.left(90)).pack(side=tk.LEFT)
tk.Button(master=root, text="Right", command=lambda: t.right(90)).pack(side=tk.RIGHT)

root.mainloop()

마우스 클릭 이벤트에 따라 움직이는 거북이 클래스 만들어보기

거북이 클래스 만들기

마우스 클릭 이벤트에 반응하기

거북이가 이동하고 있는 도중에 마우스 클릭 이벤트가 온 경우를 처리하기 위한 코드가 포함되어 있습니다.

import turtle

        super(MyTurtle, self).__init__()
        self.shape("turtle")
        self.shapesize(2, 2)
        self.color("purple")

        self.window = turtle.Screen()
        self.window.onclick(self.on_mouse_clicked)

        self.is_moving = False

    def loop(self):
