Re: [pygame] Re: Problem with mouse going back to the center of the screen



Hi,

Yes, the cursor (square) appears at the center of the screen on Linux (Debian squeeze) in full screen mode, while it is off to the side in windowed mode.

More important: please tell me if you can test it under Linux, and
tell me whether it behaves the same or not... this will help for
further investigations, thanks a lot!

You can clearly see it if you add this code in the event handler:
293                 elif event.key == K_a:
294                     pygame.mouse.set_visible(False)
295                 elif event.key == K_z:
296                     pygame.mouse.set_visible(True)
At the very beginning i do pygame.event.set_grab(False)
then if you try to press key z to show the mouse, then mouse it, press
a to hide it: you'll see the "virtual input" mode is activated.
I'm pretty sure this is a bogue.
Please tell me if you can reproduce it under Linux, thanks a lot!

Ok you were right.
Here is the summary: with Linux:
pygame.event.set_grab()
pygame.mouse.set_visible() :
grab =>  False, visible =>  False =>  "virtual input" mode
grab =>  True, visible =>  False =>  "virtual input" mode
grab =>  False, visible =>  True =>  normal mode
grab =>  True, visible =>  True =>  normal mode
So as long as the mouse is not visible, it's considered "virtual
input" mode
I'm pretty sure this is a bug.
I hope someone will try this my code under Linux and tell me if it's
the same problem or not.
You cant get the whole sourcecode here:http://olivierpons.com/einstein.tar.bz2
By the way, Enigma (the only fullscreen SDL game I've tested under
Linux) has exactly the same problem.

The only time I know of where that maybe is supposed to happen, is when the
mouse is both grabbed by the window, and invisible. SDL takes that to mean
you want "virtual input" mode, where the mouse is moved back to the center
so you can keep getting relative mouse movement infinitely in all
directions, so it can behave like a trackball. This is documented here:http://www.pygame.org/docs/ref/mouse.html
If this is your case. and relative mouse movement is fine, try using the
mouse event's .rel member instead of it's .pos member, or using
pygame.mouse.get_rel instead of .get_pos
if this is your case, but virtual input is not desireable, reconsider
whether pygame.event.set_grab(true) and pygame.mouse.set_visible(false) are
actually functions you want to call.
if this is not your case, it's a bug, and a minimal sample to reproduce
would be appreciated.

Hi!
I've got a problem with the mouse: it's going back to the center of
the screen!
I don't know where it could come from because it does this only in
full screen.
It's exactly the same problem with the game Enigma.
It seems there's a problem either with SDL or with my computer. But if
it's with my computer why only in full screen?
Did you have any trouble like that?
Thanks a lot!
