Re: [pygame] Weird lag

[René Dudfield <renesd@xxxxxxxxx>]

hi,

try timing some parts...  Then you might be able to see where the lag
is happening.

Each frame you should be able to see that they are similar values.  If
they are not, you should be able to debug where your delay is.

Here's your mainloop end part modified to add a couple of timers in...



    timer = time.time
    t1 = timer()

    pygame.display.flip()
    t2 = timer()

    clock.tick(60)
    t3 = timer()


    print "flip:%s   tick:%s:" % (t2 - t1, t3 - t2)



You can add similar timing parts for the other sections of your game.

Then add some checks like this...

if t2-t1 > 0.002:
    # dump debug information about game state.
    pass
