Mutually exclusive buttons & open window

 Print (ModifierKeys() )

brandon · January 13, 2021, 2:18pm

ah… and you have to compile while holding down the modifier to get the results:

SHIFT = 1
CTRL = 2
SHIFT + CTRL = 3
ALT = 4
SHIFT + ALT = 5
CTRL+ALT = 6
SHIFT + CTRL + ALT = 7

So what I can not test for is right-click and if I change the script to use CTRL or ALT… right click doesn’t function in a modified way so I just wanted to see if this was a known possibility?

dhj · January 13, 2021, 2:39pm

Or put it inside a widget callback and then just turn a button while holding down keys

I wanted to ask a follow up question here because it’s really a variation of sorts on this original idea.

I have three buttons: btn1, btn2, btn3.

I have another button: btn_z

I want any of the first three buttons to be able to turn on btn_z and I want the absence of all of them on to turn off btn_z. If I only turn off btn1 and btn2 for instance and btn3 is on… I want btn_z to remain on.

This is what i have so far an it’s not working:

> On WidgetValueChanged (bval: double) from btn1
>     If bval == 1.0 Then
>         SetWidgetValue(btn_z, 1)
>     Elsif bval == 0 Then
>         SetWidgetValue(btn_z, 0)
>     End
> End
> 
> On WidgetValueChanged (bval: double) from btn2
>     If bval == 1.0 Then
>         SetWidgetValue(btn_z, 1)
>     Elsif bval == 0 Then
>         SetWidgetValue(btn_z, 0)
>     End
> End
> 
> On WidgetValueChanged (bval: double) from btn3
>     If bval == 1.0 Then
>         SetWidgetValue(btn_z, 1)
>     Elsif bval == 0 Then
>         SetWidgetValue(btn_z, 0)
>     End
> End

In this script if btn1, 2, or 3 is turned off, it turns off button_z.

I tried Or but that didn’t work out. And arguments don’t seem to apply in GPscript? Is this where one would use an array? I tried that but there is no “On ArrayValueChanged” option.

Thanks for any an all help with this.

I posted a script in this thread for someone wanting a similar result as you.
Have a look and see if that helps.

In that script, StratBypass,TeleBypass, and LesPaulBypass are the equivalent of your btn1, btn2, btn3 and AmplitubeBypass is the equivalent of your btn_z…

That was close to what I wanted but it got me to a place where I could get to where I wanted to go by tweaking so thank you for that. I was able to get ‘or’ working in place of your ‘and’ statements.

Attached is what I was ultimately after… behaves like ‘solo’ mode does on a Mackie mixer:

> Var
> A : Double
> B : Double
> C : Double
> group1_btn : widget
> group2_btn : widget
> group3_btn : widget
> group5_btn : widget
> 
> On WidgetValueChanged(newValue : double) from group1_btn
> A = GetWidgetValue(group1_btn)
> B = GetWidgetValue(group2_btn)
> C = GetWidgetValue(group3_btn)
>     If A == 1.0 or B == 1.0 or C == 1.0
>         then SetWidgetValue(group5_btn,1.0)
>     Elsif newValue == 0.0
>         then SetWidgetValue(group5_btn,0.0)
>     End
> End
> 
> On WidgetValueChanged(newValue : double) from group2_btn
> A = GetWidgetValue(group1_btn)
> B = GetWidgetValue(group2_btn)
> C = GetWidgetValue(group3_btn)
>     If A == 1.0 or B == 1.0 or C == 1.0
>         then SetWidgetValue(group5_btn,1.0)
>     Elsif newValue == 0.0
>         then SetWidgetValue(group5_btn,0.0)
>     End
> End
> 
> On WidgetValueChanged(newValue : double) from group3_btn
> A = GetWidgetValue(group1_btn)
> B = GetWidgetValue(group2_btn)
> C = GetWidgetValue(group3_btn)
>     If A == 1.0 or B == 1.0 or C == 1.0
>         then SetWidgetValue(group5_btn,1.0)
>     Elsif newValue == 0.0
>         then SetWidgetValue(group5_btn,0.0)
>     End
> End

I knew you’d pick that up quickly! I’m glad it helped. Well done.

So I evolved this a bit further so that if the target button was already on the source buttons wouldn’t have any effect. This was to solve an issue where it was doing something unexpected elsewhere.

However when I added the and statement… while it complies and still works, the result is the or statement just before it, in this case the “D” value, creates the issue where the “D” button turns on and off the target button, but it gets ignored if any other button is the second to last to be turned off. No one cares what “D” thinks!

I swapped A for D and got the same result only on the A button so it has something to do with the syntax of adding the “and” argument right after the last “or” argument.

here’s just the last button’s script:

> On WidgetValueChanged(newValue : double) from group4_aux_send_btn
> A = GetWidgetValue(group1_aux_send_btn)
> B = GetWidgetValue(group2_aux_send_btn)
> C = GetWidgetValue(group3_aux_send_btn)
> D = GetWidgetValue(group4_aux_send_btn)
> E = GetWidgetValue(group5_btn1)
>     If A == 1.0 or B == 1.0 or C == 1.0 **or D == 1.0 and E == 0.0**
>         then SetWidgetValue(group5_btn1,1.0)
>     Elsif newValue == 0.0
>         then SetWidgetValue(group5_btn1,0.0)
>     End
> End

Would you have any guidance on how to fix this so D isn’t ignored by A, B or C?

Many thanks.

Hmmm, if you had the arithmetic expression

 1 + 2 + 3 + 4 * 5

what value do you expect this to evaluate to (without actually trying it in GP Script)

brandon · February 6, 2021, 1:14am

fifty or twentysix

dunno

edm11 · February 6, 2021, 1:15am

@dhj are you implying that

If A == 1.0 or B == 1.0 or C == 1.0 or D == 1.0 and E == 0.0

gets evaluated in the script as

If A == 1.0 or B == 1.0 or C == 1.0 or (D == 1.0 and E == 0.0)
?

dhj · February 6, 2021, 1:23am

Yes !

dhj · February 6, 2021, 1:24am

twenty six is the correct answer with conventional precedence rules

brandon · February 6, 2021, 1:31am

@dhj

So what I really want, following your analogy is:

1 * 5 + 2 * 5 + 3 * 5 + 4 * 5
(= 50)

So…

If A == 1.0 and E == 0.0 or B == 1.0 and E == 0.0 or C == 1.0 and E == 0.0 or D == 1.0 and E == 0.0

?

that has the opposite effect I am after

dhj · February 6, 2021, 2:06am

Which is the same as
(1 + 2 + 3 + 4) * 5

I don’t know what you really want, I didn’t read your script in any detail, just noticed the end of that boolean and guessed you were probably being bitten by precedence. What you might have wanted (but again, I don’t know what you’re trying to do) is

 If (A == 1.0 or B == 1.0 or C == 1.0 or D == 1.0) and E == 0.0

brandon · February 6, 2021, 2:24am

that is more elegant that this…

…but it functions the same.

the result is that if A, B, C or D were once 1.0 but after a WidgetValueChanged are now 0.0, then E will now == 0.0

what I had originally which nearly worked as desired, (except that A, B and C were ignoring if D == 1.0) resulted in E == 0.0 unless A or B or C == 1.0 in which case E also == 1.0.

In plain English, I’d like it if any button (ABCD) were turned on and E were off already, E gets turned on… but if (ABCD) buttons are all turned off then if E is on, E gets switched off. I had this working but I needed to add the disclaimer that if E were already on and ABCD gets switched on, E ignores any action because it was impacting something that E was linked to elsewhere.

When I added that “and” argument it complicated things.

The only way I can think I can do this would likely take 16 full arguments per button to cross reference the state of any combination… but I am sure there is a better way.

yes! thank you. learning!

edm11 · February 6, 2021, 2:39am

Me too…

brandon · February 6, 2021, 4:12am

Is there a way to have multiple actions from a WidgetValueChanged?

For instance… this script opens a plugin window only when a modifier key is held down.:

On WidgetValueChanged (btval : double) from group1_btn1
if ModifierKeys() == 2
and btval > 0.5
then OpenPlugin(group1_sound1)
Else ClosePlugin(group1_sound1)
End
End

If I add another script after this that is also triggered from that same button i get this:

Semantic error in “Main”: On WidgetValueChanged already defined for this widget

What I would like to do is combine two functions into the same button.

Open the plugin window when a modifier key is held down
Bypass/Un-bypass toggle the plugin regardless if the modifier key is held down

I realize that Bypass is easily mapped as a plugin parameter but I want to script it to the plugin handle and not use the plugin itself.

I have tried adding SetPluginBypassed in the above script as an Elsif addendum but I end up with not a sufficient statement or an incompatible value.
