Pygame freezes after certain time

[XavierPlatinum]

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()

It's because your loop is for i in range 100. So it's making 100 moves then then sets run to false. I don't know how that could have been different in linux.

Your program works fine! lol
