为什么我在pygame中发生的碰撞无法正常工作？

Question

我是第一次使用python pygame编写游戏。它基于飘扬的小鸟和游戏的主要思想是相同的。但是碰撞代码无法正常运行，有时游戏会停止，并且说我什么都没击中就输了。 这是我的代码片段：

import pygame
import random
import os
import time
import sys
import math
from datetime import datetime

pygame.init()

WIDTH = 500
HEIGHT = 600
Black = (0, 0, 0)

pygame.display.set_caption("FlappyBee")
screen = pygame.display.set_mode((WIDTH, HEIGHT))

def lost(txt, x, y, size):
    cz = pygame.font.SysFont("Times New Roman", size)
    rend = cz.render(txt, 1, (255, 0, 0))
    x = (WIDTH - rend.get_rect().width) / 2
    y = (HEIGHT - rend.get_rect().height) / 2
    screen.blit(rend, (x, y))

    pygame.display.update()

class Bee:
    ANIMATION_TIME = 5
    MAX_ROTATION = 30
    ROT_VEL = 20
    BEE = BEE_IMG

    def __init__(self, x, y):
        self.x = x
        self.y = y
        self.tilt = 0
        self.tick_count = 0
        self.vel = 0
        self.height = self.y
        self.img_count = 0
        self.img = self.BEE
        self.hitbox = (self.x + 220, self.y + 220, 55, 55)

    def jump(self):
        self.vel = -9.5
        self.tick_count = 0
        self.height = self.y

    def move(self):
        self.tick_count += 1

        d = self.vel * self.tick_count + 1.5 * self.tick_count ** 2

        if d >= 16:
            d = 16
        if d < 0:
            d -= 2

        self.y = self.y + d

        if d < 0 or self.y < self.height:
            if self.tilt < self.MAX_ROTATION:
                self.tilt = self.MAX_ROTATION
        else:
            if self.tilt > -90:
                self.tilt -= self.ROT_VEL

    def draw(self, screen):
        self.img_count += 1

        if self.img_count < self.ANIMATION_TIME:
            self.img = self.BEE
            self.img_count = 0

        rotated_image = pygame.transform.rotate(self.img, self.tilt)
        new_rect = rotated_image.get_rect(center=self.img.get_rect(topleft=(self.x, self.y)).center)
        screen.blit(rotated_image, new_rect.topleft)
        self.hitbox = (self.x + 220, self.y + 220, 55, 55)
        # pygame.draw.rect(screen, (255, 0, 0), self.hitbox, 2)

    def hit(self):
        screen.fill(Black)
        lost("you lost", 40, 100, 70)
        time.sleep(3)

class Trunk:
    GAP = 200
    VEL = 5

    def __init__(self, x):
        self.x = x
        self.height = 0

        self.BOTTOMTRUNK = TRUNK
        self.passed = False
        self.set_height()
        self.hitboxtop = (self.x + 80, self.top, 80, 490)
        self.hitboxbottom = (self.x + 80, self.bottom + 10, 80, 490)

    def set_height(self):
        self.height = random.randrange(50, 400)
        self.top = self.height - self.TOPTRUNK.get_height()
        self.bottom = self.height + self.GAP

    def move(self):
        self.x -= self.VEL

    def draw(self, screen):

    trunks = [Trunk(400)]

        draw_window(screen, bee, trunks)

        add_trunk = False
        rem = []
        for trunk in trunks:

我感觉有时候，当屏幕上有两个树干时，蜜蜂不知道应该集中在哪一个上。我不知道我应该改变什么。 如果有人可以帮助我，那就太好了。
