Hi Diliup,
I believe that there is a slight gain in performance when using set_allowed
so that only certain events are added to the queue. I have never profiled
it, but I doubt that it's terribly more efficient. I would just do the
usual method of polling for events each loop, tracking the held keys, and
handling them appropriately, and see if that meets your requirements. For
your case, you may not really have to track held keys, and could just run a
function to turn tones on if a key pressed, and off when it is released:
while True:
tslf = fpsClock.tick( FPS )
for event in pygame.events.get():
if event.type == KEYDOWN:
if event.key == K_q:
play_tone( q )
elif event.key == K_2:
play_tone( 2 )
.....
elif event.type == KEYUP:
if event.key == K_q:
stop_tone( q )
elif event.key == K_2:
stop_tone( 2 )
# draw and update buttons here...
pygame.display.update()
Thank you,
Noel
