force screen refresh/update?

Hi,

I have

Code:

gScreenTextObj = viz.addText3D('',parent=viz.SCREEN, pos=( 0, 0, 0 ) )

and then later in a function that was called following a key press using vizact.onkeydown()

Code:

gScreenTextObj.message = "asdf"

Is there anyway I can force the screen update to take place (displaying the new text 'asdf')? At present it waits until the function ends and flow returns to the main loop.

thanks,

John

Can you post example code that reproduces the issue?

pressing '1' displays a message, pressing '2' clears it, however it blocks waiting for the keyboard input on the viz.input() call.

i would like to flush the screen update before blocking for the keyboard input if possible.

Thanks,
John

Code:

import viz, vizconnect, vizact, vizinput, viztask



viz.setMultiSample(4)

gScreenTextObj = None



def keyPressed_1():

    global gScreenTextObj

    gScreenTextObj.message("1 pressed")



def keyPressed_2():

    global gScreenTextObj

    gScreenTextObj.message("") # try to clear the message

    gCurrentPID = int( vizinput.input("Enter ID : "))

    gGAB = vizinput.choose( "Gender: ", ['Male', 'Female'] )



def exitExperiment():

    viz.quit()

    

def vizconn_kbd_mouse():

        vizconnect.go('vizconnect_kbd_mouse_monitor.py')



def experiment():

    global gTracker, gScreenTextObj



    vizconn_kbd_mouse()

    gTracker = vizconnect.getTracker('mouse_and_keyboard_walking')

    room = viz.add('room4.osgb')

    

    vizact.onkeydown('x', exitExperiment )

    vizact.onkeydown('1', keyPressed_1 )

    vizact.onkeydown('2', keyPressed_2 )

    

    gScreenTextObj = viz.addText3D('',parent=viz.SCREEN, pos=( 0, 0, 0 ) ) #write on screen messages here

    

# We've defined all our functions, now lets start our experiment!

viztask.schedule(experiment)

I had the same problem, I solve it by starting the message variable in this way

Quote:

#starting variable
gScreenTextObj = vizinfo.add( "" )

#change the valor
def keyPressed_1():
global gScreenTextObj
gScreenTextObj.message('1 pressed')

vizact.onkeydown('1', keyPressed_1 )
