Topic: VDJScript: Concurent acces on var with "while_pressed"

This topic is old and might contain outdated or incorrect information.

Hi, on my controler i have 2 buttons was doing the same thing on same variable:
set "$global_var" 1 while_pressed

it's working well, but if I press the 2 buttons simultaneously: The $global_var was set to 1 continuously when I release the buttons

to avoid it, I tried this but it's not working at all (the var is not changed)
up: set "$global_var" 0 : set "$global_var" 1

and i tried this but it does not change the behaviour:
set "$global_var" 1 while_pressed && up: set "$global_var" 0 : nothing

do you have any idea.
Thanks !!

Yes, whilepressed is "and repeat as long as key is pressed"
use "temporary" to "wait for key to release"

if var was initialy set to zero: push Button1 remember it was 0 set it to 1
while Button1 is down pressing Button2 : it remember it is 1 set to 1

set "$global_var" 1 while_pressed

press button 1, set to 1 remembered 0
press button 2, set to 1 remembered 1

release button 1, set back to remembered 0
release button 2, set back to remembered 1

up ? set "$global_var" 0 : set "$global_var" 1 whilepressed

press button 1, remember 0 set to 1
press button 2, remembe 1 set to 0

release button 1, up set to 0 set back to remembered 0
release button 2, up set to 0 set back to remembered 1

up ? set "$global_var" 0 : set "$global_var" 1

press button 1, set to 1 remembered nothing
press button 2, set to 1 remembered nothing

release button 1, up set to 0
button 2 already down set to 1 again
release button 2, up set to 0

up ? set "$global_var" 0 : set "$global_var" 1 temporary
press button 1, set to 1 remember 0
press button 2, set to 0 remember 1

release button 1, set to remembered 0, up set to 0
release button 2, set to remembered 1, up set to 0

set "$global_var" 1 temporary
press button 1, set to 1 remember 0
press button 2, set to 0 remember 1

release button 1, set to remembered 0
release button 2, set to remembered 1

the release order differ between whilepressed and temporary

Thanks a lot for your clear explanation how works "while_pressed" and "temporary"
a lot of reply need to be on wiki :)

but on this script my issue is a test with ":" insted of "?"...
up: set "$global_var" 0 : set "$global_var" 1

I don't know why I didn't see it...
Sorry for this simple syntax issue...

Thanks again for your help
