Tkinter 对象碰撞？

Question

所以我制作了一个 "game"，它有 2 个球，一个绿色球和一个红色球，你可以移动红色球，但是当它与绿色球碰撞时，我希望它显示一条成功消息通过在控制台打印！这是我的代码。

__author__ = 'Zac'
from Tkinter import *
from random import randint
class Application:
    def circle(self, r, x, y):
        return (x-r, y-r, x+r, y+r)

    def square(self, s, x, y):
        return (x, y, s, s)

    def __init__(self, canvas, r, x, y, **kwargs):
        self.canvas = canvas
        self.r = r
        self.x = x
        self.y = y
        self.ball = canvas.create_oval(self.circle(r, x, y), **kwargs)


root = Tk()
canvas = Canvas(root, width = 1000, height = 1000)
canvas.pack()

ball1 = Application(canvas, 20, 50, 50, fill='red')
ball2 = Application(canvas, 30, 200, 250, fill='green')

def forward(event):
    canvas.delete(ball1.ball)
    ball1.y -= 5
    ball1.ball = canvas.create_oval(ball1.circle(ball1.r, ball1.x, ball1.y), fill='red')

def backward(event):
    canvas.delete(ball1.ball)
    ball1.y += 5
    ball1.ball = canvas.create_oval(ball1.circle(ball1.r, ball1.x, ball1.y), fill='red')

def left(event):
    canvas.delete(ball1.ball)
    ball1.x -= 5
    ball1.ball = canvas.create_oval(ball1.circle(ball1.r, ball1.x, ball1.y), fill='red')

def right(event):
    canvas.delete(ball1.ball)
    ball1.x += 5
    ball1.ball = canvas.create_oval(ball1.circle(ball1.r, ball1.x, ball1.y), fill='red')

root.bind('<w>', forward)
root.bind('<s>', backward)
root.bind('<a>', left)
root.bind('<d>', right)
root.mainloop()

好的，我是这样做的！

我添加了这个功能

def collide():
    x_diff = abs(ball1.x - ball2.x)
    y_diff = abs(ball1.y - ball2.y)

    if x_diff <= 49:
        if y_diff <= 49:
            print "COLLIDED"

每次你运行移动碰撞函数的函数都会被调用，如果触摸它会打印 "Collided"

感谢@CurlyJoe 获取检查它们之间距离的代码！
