我试图做一个游戏，有多个物体下降，你必须避免，每个在不同的高度。然而，我最终只有8块在顶部和1下降的时间。有人能帮助我理解为什么并解决它吗？我怀疑与缩进的东西。
代码如下所示。

import pygame
import random
import sys

import os
from tkinter import *
from tkinter import messagebox

#some config

print(os.getcwd())

pygame.init()

    player_pos = [400, 475]
    player_size = 50

    myFont = pygame.font.SysFont("DroidSans", 35)

    pygame.display.set_caption('Trash Dodge, Science Project,  By: Benjamin Bernstein')

    pygame.mouse.set_visible(0)
