对象之间的Tkinter碰撞？

Question

我正在做一个小项目（更多游戏），完全陷入了碰撞。游戏非常简单-有一个玩家（一个蓝色方块）试图避开移动矩形（向上/向下）（使用箭头键）越过屏幕。

这是它的样子：

我尝试了canvas.coords()方法，但似乎无法使其正常工作。我将所有游戏逻辑放在一个带有两个类的文件中，而GUI放在另一个具有自己类的文件中。

from project.helpers import *


class Player:

    def __init__(self, x=100, y=200, color="blue"):

        self.x = x
        self.y = y
        self.color = color

    def render(self, canvas):

        canvas.create_rectangle(self.x, self.y, self.x+50, self.y+50, fill=self.color)

    def move_right(self):

        self.x += 10

    def move_left(self):

        self.x -= 10

    def move_up(self):

        self.y -= 10

    def move_down(self):

        self.y += 10

    def get_x(self):

        return self.x

    def get_y(self):

        return self.y


class Rectangles:

    def __init__(self, x=200, y=300, vel_y=randint(3, 10)):

        self.x = x
        self.y = y
        self.vel_y = vel_y
        self.color = get_random_color()

    def render(self, canvas):

        self.rect1 = canvas.create_rectangle(self.x, self.y, self.x+50, self.y+200, fill=self.color)
        self.rect2 = canvas.create_rectangle(self.x+200, self.y, self.x+250, self.y+200, fill=self.color)
        self.rect3 = canvas.create_rectangle(self.x+400, self.y, self.x + 450, self.y+200, fill=self.color)
        self.rect4 = canvas.create_rectangle(self.x+600, self.y, self.x+650, self.y+200, fill=self.color)
        self.rect5 = canvas.create_rectangle(self.x+800, self.y, self.x+850, self.y+200, fill=self.color)

    def move(self, canvas):

        self.y += self.vel_y

        if self.y < 0 or self.y > canvas.winfo_height():  # top & bottom of canvas, don't need to change x
            self.vel_y = -self.vel_y

    def get_position(self, canvas):

        return canvas.coords(self.rect1)

我正在尝试获取它，以便如果我用箭头键移动播放器并且与一个移动的矩形之一“碰撞”，则会在画布上打印一条消息，说“游戏结束”。
