Hi,
In the following code, I am trying to run "black" screen for 3 seconds
and respectively 2 seconds "white" screen. Black routine takes 3
seconds and white 2 seconds, 2 x black + white = 8 seconds which
should be the expected value but when I run it I get black-white-black-
white instead of black-white-black. Couldn't figure out what is
wrong thus sharing the code as well ;
white = False
while(end<8.00):
end = time.time() - start
you're setting end's value before the display happens, so while tests
the values 0,3,5 before getting after the fourth pass 8. Move this
after to white = note white and I suspect you'll be OK.
HTH,
Emile
if white:
screen.fill((255, 255, 255))
time.sleep(2)
else:
screen.fill((0, 0, 0))
time.sleep(3)
white = not white
pygame.display.update()
pygame.quit()
