Re: [pygame] Pygame without screen

[Bert Haverkamp <bert@xxxxxxxxxxxxxxxx>]

Hi Winkleink,

Thanks for the hint. Indeed I heard/read somewhere that joysticks events are working. But keyboard events somehow not.
I cut an pasted a bit from your code and came up with the testprogramm below. If you run it, the joystick will trigger events, but the keyboard doesn't
------------------------
import pygame, os, sys
from pygame import locals

os.environ['SDL_VIDEODRIVER'] = 'dummy'
pygame.init()
pygame.joystick.init()

try:
ÂÂ j = pygame.joystick.Joystick(0) # create a joystick instance
ÂÂ j.init() # init instance
ÂÂ print 'Enabled joystick: ' + j.get_name()
except pygame.error:
ÂÂ print 'no joystick found.'

while True:
 for event in pygame.event.get():
ÂÂÂ print 'event detected'
ÂÂÂ if event.type == pygame.QUIT:
ÂÂÂÂÂ sys.exit()
ÂÂÂ if event.type == pygame.KEYDOWN:
ÂÂÂÂÂ print 'key pressed'
ÂÂÂ if event.type == pygame.locals.JOYAXISMOTION: # Read Analog Joystick Axis
ÂÂÂÂÂÂ print 'joystick moved'
---------------------------------------------

I use dummy in the following project and it worked.
There may be something other than that one line that needs to be sorted.

Hello all,

Maybe it has been asked before. But I only see older posts on this topic. I'm hoping the situation has changed now.
I'm trying to make a game where there is no screen needed, but physical actuators (motors, steppers, a beeper)

But without a screen defined, I cannot seem to get events to work properly
In particular cannot use the keydown and keyup events. The events don't seem to happen.

I read somewhere that I should use the dummy screen with

os.environ['SDL_VIDEODRIVER'] = 'dummy'

But this also doesn't seem to help.
Is there a way to get the events functioning without a screen? If so, how. If not, would that be an possible addition in a future version?

Regards,

Bert
