I'm quite new to pygame and am currently doing a school project. My problem is that i have been attempting to create a border for my game so my charectar cant go out from the screen.
Heres my code so far:
# This imports the Pygame Module / loads pygame keywords
import pygame
# This lets python use my file system
import sys
# This helps python identify my OS, which is Windows 10
import os

I know it has somthing to do with classes and localisation of code and ive tried to fix that many times but it never seems to work, either not working once executed or never even executing. If anyone has any suggestions, that would be great! Also apoligies for the very messy and unorganised code, if anyone has any further tips on how i should improve my code, though not neccesary, I'll be in your debt!
