Закрепление границ экрана спрайтами

Question

Я пытаюсь сделать эту игру, и в данный момент мне удалось получить ее, чтобы игрок не мог двигаться влево или вправо за указанную границу. Однако, когда они прыгают, они могут упасть ниже нижней части экрана. Мне было интересно, если кто-нибудь может помочь сделать это, чтобы этого не произошло. Смотрите код ниже:

import tkinter as tk
from tkinter import *
import pygame as pg
import os

        self.bind("<Enter>", self.on_enter)
        self.bind("<Leave>", self.on_leave)

    def on_enter(self, e):
        self['background'] = self['activebackground']
