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
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()
Could it be because you're setting 'end' after testing it?
It might be simpler as:
while time.time() - start < 8:
Also, should it really be sleeping before updating the display? I
would've thought that it should be sleeping _after_ updating the
display.
