pygame.error: video system not initialized

Question

so I get this error when I try to run my pygame code: pygame.error: video system not initialized

i specify where the wing IDE tells me it is in the code below

Answer 1

If you using class for your pygame window don't use pygame.init() in your class. Use pygame.init() at bottom the libraries.

Answer 2

I had this issue recently, and I discovered a strange and unusual bug in the code that I'd written -- only after reading it and re-reading it a dozen times over a 10 minute stretch, trying to launch the file (which looked perfect) a dozen times.

There was pygame.init(). There was screen = pygame.display.set_mode((size)) with the variable size in position to be available in the global namespace.

Turns out it was the main game loop.

# main game loop
while RUNNING == True:
    for tneve in pygame.event.get():
        if tneve.type == QUIT:
            print(tneve)
            RUNNING = False
        loop()
        render()
        CLOCK.tick(FPS)
    cleanup()
# End

What a pain!

P.S. The problem is the one-stop-too-far indentation of everything below RUNNING = False.

I made some modifications to your code:

import os
import sys
import math
import pygame
import pygame.mixer
from pygame.locals import *

pygame.init()
black = 0, 0, 0
white = 255, 255, 255
red = 255, 0, 0
green = 0, 255, 0
blue = 0, 0, 255

screen = pygame.display.set_mode((600, 400))

clock = pygame.time.Clock()

pygame.display.set_caption("Physics")


while True:
    clock.tick(120)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
    screen.fill(green)

    pygame.display.flip()

Answer 4

You have to add:

pygame.init()

Before you quit the display you should stop the while loop.

Answer 5

You get an error because you try to set the window title (with set_caption()) but you haven't created a pygame window, so your screen variable is just a tuple containing the size of your future window.

To create a pygame window, you have to call pygame.display.set_mode(windowSize).

Good luck :)

Answer 6

1 this problem happens when you using a beta version.

2 so my suggestion is please use the new, old version(If now lunch 3.8 python, you need to install python 3.7)

3 Now goto python terminal and install pygame (pip install pygame)

4 now the problem is solved...
