Re: [pygame] BUG keyboard events

[Виталий <vitalik1231@xxxxxxxxx>]

No, you're wrong.

There's TWO while cycles, and second poll event until pygame.NOEVENT, so I got ALL events (I also tested with event.get(), bug the same)

I know how to use time.sleep, but this bug works only when CPU is used (that's why it called exactly "eat_cpu" not sleep or delay or wait or whatever).

pygame.key.name returns human-readable name of key, for debug purpose it's better use get_key_info.

After these changes, all your `break` statements are no longer needed.

First things I noticed, you are only parsing one event per game loop. You're missing a ton of events. Instead use:

    for event in pygame.event.get():

 

For  `eat_cpu`, instead sleeping.  Use either `time.wait` or `time.delay` depending on your requirement. Sleep doesn't use your CPU to delay. And `eat_cpu` has a undefined time.

Your main loop becomes:

    while Working:
        for event in pygame.event.get():
            # handle events

        # math

        # render

`get_key_info(k)` becomes:

    def get_key_info(k):
        return pygame.key.name(k)

Hi, I got bug in pygame
If I change window resolution in keyboard handler then I got strange KEYUP event:
<Event(2-KeyDown {'scancode': 114, 'key': 275, 'unicode': u'', 'mod': 0})> (K_RIGHT)
<Event(3-KeyUp {'scancode': 0, 'key': 275, 'mod': 0})> (K_RIGHT) # HERE
<Event(3-KeyUp {'scancode': 114, 'key': 275, 'mod': 0})> (K_RIGHT)

but if I hit key very quickly, then I got that:
<Event(2-KeyDown {'scancode': 114, 'key': 275, 'unicode': u'', 'mod': 0})> (K_RIGHT)
<Event(3-KeyUp {'scancode': 0, 'key': 275, 'mod': 0})> (K_RIGHT)

And sometimes pygame stops to receive any keyboard events, but mouse and all other is ok (ALT + F4 still works)

To check bug try to press "a", "s", "d", "right" at the same time few times, after few tries pygame stops to receive any keyboard events.
