I have the following script, but it is not performing as expected. I'd like to hide the green images if that column is null.

Dim title = Input.Find("CUT TEST.gtzip")

Dim transferredFields = New String() {"Transferred10", "Transferred8", "Transferred8"}
Dim imageFields = New String() {"Image10.Source", "Image9.Source", "Image8.Source"}

For i As Integer = 0 To transferredFields.Length - 1
Dim value = title.Text(transferredFields(i)).Trim().ToLower()

If value = "q" Then
title.Text(imageFields(i)) = "Image10.Source" ' <-- Replace with actual image name if different
Console.WriteLine(transferredFields(i) & " = Q → Showing " & imageFields(i))
Else
title.Text(imageFields(i)) = ""
Console.WriteLine(transferredFields(i) & " ≠ Q → Hiding " & imageFields(i))
End If
Next

Any advice?

Hi. This script to my little knowledge it seems to me in-complete. Correct me if i am wrong but i dont see in your code a command like "api function"-->do this when the "if" situation is meet
I see in vmix api that exist https://vmixapi.com/?function=SetImageVisibleOn and https://vmixapi.com/?function=SetImageVisibleOff in order to set the image visibility on or off.
In your script i dont see something like this,that will tell vmix how to hide/unhide the image when the condition fits
Edit. Based in the scripting of dummies thread and https://tvcrew.ch/wiki/d...hp?id=scripting_examples a working script that do what you need will be like this
Code:

dim a as string

do while true


a= Input.Find("scoreboard").Text("Title Text.Text")


if a = "" then
  
  API.Function("SetImageVisibleOFF",Input:="scoreboard",SelectedName:="Image2.Source")
  else
   API.Function("SetImageVisibleON",Input:="scoreboard",SelectedName:="Image2.Source")
  
end if

sleep(500)

loop

replace with your input title names and try if works

This should suffice?


Dim title = Input.Find("cut_test.gtzip")
Dim Transferred(10) As String

Do While True
For i As Integer = 1 To 10
Transferred(i) = title.Text("Transferred" & i).Trim().ToLower()

If Transferred(i) = "Q" Then
API.Function("SetImageVisibleON", Input:="cut_test.gtzip", SelectedName:="Image" & i & ".Source")
Console.WriteLine("Transferred" & i & " = q → Showing image " & i)
Else
API.Function("SetImageVisibleOFF", Input:="cut_test.gtzip", SelectedName:="Image" & i & ".Source")
Console.WriteLine("Transferred" & i & " ≠ q → Hiding image " & i)
End If
Next

Sleep(500)
Loop

I dont know if suffice or not,because i dont have a sample image to check. Anyway this time i described to AI what to do and it come up with the following. In my example i assume that TitleText1.Text layer is "pair" with Image1.Source and so on until to 10.
Code:

Dim a As String
Dim i As Integer

Do While True

    For i = 1 To 10
        ' Διαβάζουμε το αντίστοιχο TitleText{i}.Text
        a = Input.Find("scoreboard").Text("TitleText" & i & ".Text")

        ' Αν το κείμενο είναι κενό ή μόνο whitespace, κλείνουμε το Image.
        If String.IsNullOrWhiteSpace(a) Then
            API.Function("SetImageVisibleOFF", Input:="scoreboard", SelectedName:="Image" & i & ".Source")
        Else
            API.Function("SetImageVisibleON",  Input:="scoreboard", SelectedName:="Image" & i & ".Source")
        End If
    Next

    Sleep(500)  
Loop

i cannot say if it works or not but if yours not work,try it.

How did you build your GT title ?? Did you import a psd with layers if so you can’t turn images off/on , they must have been imported into the GT title as separate images

It is an imported .psd, but the squares in question were recreated in GT.

I threw in the towel and ended up modifying the incoming JSON to include columns with hyperlinks to the images to display depending on the status of the column with the Q's in it. If a Q is present, the green box image is linked for display. If not, a transparent image displays. It works perfectly.
