Pygame freezes after certain time
#1
Hi! Trying to make a previz window for testing a puzzle game while in development, but it keeps freezing after certain time, I am very new to pygame, so not sure what's wrong! Thanks
import pygame
from random import randint

font_color = (0, 255, 200)
bkg_color = (0, 0, 0)
ltr_range = 10
gap = 20
cube_size = 800
speed = 1

matrix = [[chr(65+x+y) for y in range(ltr_range)] for x in range(ltr_range)]


def draw_matrix():
    for x in range(ltr_range):
        for y in range(ltr_range):
            win.blit(font.render(matrix[x][y], True, font_color),
                     (gap + (cube_size // ltr_range * y), gap + (cube_size // ltr_range * x)))
    pygame.display.update()


def matrix_row_turn_right(line=0, steps=0):
    empty = matrix[line][-steps:]
    for x in range(len(matrix[line]) - steps - 1, -1, -1):
        matrix[line][x + steps] = matrix[line][x]
    for y in range(len(empty)):
        matrix[line][y] = empty[y]


def matrix_col_turn_up(line=0, steps=0):
    empty = [matrix[x][line] for x in range(steps)]
    for y in range(len(matrix) - steps):
        matrix[y][line] = matrix[y + steps][line]
    for z in range(len(matrix) - steps, len(matrix)):
        matrix[z][line] = empty[abs(len(matrix) - steps - z)]


def anim_move_right(line):
    for x in range(1, cube_size // ltr_range):
        pygame.draw.rect(win, bkg_color, (0, (cube_size // ltr_range * line),
                                          cube_size, cube_size // ltr_range))
        for y in range(ltr_range):
            win.blit(font.render(matrix[line][y], True, font_color),
                     ((gap + (cube_size // ltr_range * y) + x),
                      gap + (cube_size // ltr_range * line)))
        win.blit(font.render(matrix[line][-1], True, font_color),
                 ((0 - (cube_size // ltr_range) + gap + x), gap + (cube_size // ltr_range * line)))
        pygame.time.delay(speed)
        pygame.display.update()
    matrix_row_turn_right(line, 1)
    draw_matrix()


def anim_move_up(line):
    draw_matrix()
    for x in range(1, cube_size // ltr_range):
        pygame.draw.rect(win, bkg_color, ((gap + (cube_size // ltr_range) * line),
                                          0, cube_size // ltr_range, cube_size))
        for y in range(ltr_range):
            win.blit(font.render(matrix[y][line], True, font_color),
                     (
                     gap + cube_size // ltr_range * line, (gap + (cube_size // ltr_range * y) - x)))
        win.blit(font.render(matrix[0][line], True, font_color),
                 (gap + (cube_size // ltr_range * line), (cube_size + gap - x)))
        pygame.time.delay(speed)
        pygame.display.update()
    matrix_col_turn_up(line, 1)
    draw_matrix()


pygame.init()
win = pygame.display.set_mode((cube_size, cube_size))
pygame.display.set_caption("Word Puzzle preViz")
font = pygame.font.SysFont('Ariel', cube_size // ltr_range)

run = True
while run:
    draw_matrix()
    pygame.time.delay(1000)
    for i in range(100):
        if i % 2 == 0:
            anim_move_right(randint(0, ltr_range-1))
        else:
            anim_move_up(randint(0, ltr_range-1))
    run = False

pygame.quit()

what's the objective of the game? I ran your script 3 times without any problems.
I'm using linux. I put in a print statement counting the loops thinking if it was odd it would be a up animation and even left to right, but it didn't hang or crash.

For some reason it freezes on Windows, I'll check on linux later, but it worked once I used a while loop instead of iterator and added event check. It's a simple letter puzzle game for assembling words, kind of like 2D rubik's cube.
count = 0
while count < 100:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    if count % 2 == 0:
        anim_move_right(randint(0, ltr_range - 1))
    else:
        anim_move_up(randint(0, ltr_range - 1))
    count += 1

pygame.quit()
Thanks for checking!
