如何检测类中pygame表面的点击

Question

我有一个模拟器，您可以在其中砍树，所以我希望它是这样，以便当我单击树时，它将从3秒开始倒数，然后消失。我将树分类为Tree类，但是现在我不知道如何在if语句中获得它们的位置，因为它们不再是真正的pygame表面。如果有人在课堂上，有人可以告诉我如何获得职位吗？代码如下：

import pygame
import time
pygame.init()
root = pygame.display.set_mode((603, 573))
pygame.display.set_caption("Foraging Simulator")

width = 10
leaves_width = 30
height = 20
leaves_height = 10
x = 0
tree_trunk_x = 10
y = 0
tree_trunk_y = 10
vel = 5
brown = (150, 75, 0)

    def __init__(self, tree_x, tree_y, tree_property_name):
        self.tree_x = tree_x
        self.tree_y = tree_y
        self.tree_property_name = tree_property_name
    def destroy(self):
        count = pygame.font.SysFont('Tahoma', 18, True, False)
        countdown = count.render('3', True, (0, 0, 0))
        root.blit(countdown, (583, 553))
        pygame.display.update()
        time.sleep(1)

您的树类可以更好地组织。您需要做的一件事是将树的矩形放入自己的类变量中，以便您可以访问它们。这是一个如何做的例子。有关我所做的更改，请参见代码注释：

root = pygame.display.set_mode((603, 573))

black = (0, 0, 0)
width = 10
leaves_width = 30
height = 20
leaves_height = 10
x = 0
tree_trunk_x = 10
y = 0
tree_trunk_y = 10
vel = 5
brown = (150, 75, 0)

        self.tree_x = tree_x
        self.tree_y = tree_y
        self.tree_property_name = tree_property_name

    def destroy(self):
