I used the Lines project as an example,

Public Sub Tick (GS As X2GameStep)
    HandleTouch 'not related to this question
    Dim touch As X2Touch = Multitouch.GetSingleTouch(Panel1)
    If touch.IsInitialized Then
        If touch.EventCounter = 0 Then
            Label1.Text="DOWN"
        Else If touch.FingerUp Then
            Label1.Text="UP"
        Else
            Label1.Text="IS MOVING"
        End If
    End If
End Sub

This is a very cool example

1. Check the note in the Initialize method:

View attachment 124996
(thouch = though - fixed).

2. It is not a good idea to handle events outside of the game loop.
3. The "X2" way to implement is with:

B4X:

Public Sub Tick (GS As X2GameStep)
    HandleTouch 'not related to this question
    Dim touch As X2Touch = Multitouch.GetSingleTouch(Panel1)
    If touch.IsInitialized Then
        If touch.EventCounter = 0 Then
            Label1.Text="DOWN"
        Else If touch.FingerUp Then
            Label1.Text="UP"
        Else
            Label1.Text="IS MOVING"
        End If
    End If
End Sub

And don't forget to set the Event Name of Panel1 to Panel.

#If B4J
Private Sub Panel_Touch (Action As Int, X As Float, Y As Float)
    Multitouch.B4JDelegateTouchEvent(Sender, Action, X, Y)
End Sub
#Else If B4i
Private Sub Panel_Multitouch (Stage As Int, Data As Object)
    Multitouch.B4iDelegateMultitouchEvent(Sender, Stage, Data)
End Sub
#End If

1. Make sure to set the event name to Panel.
2. I forgot to write that you should add it on this line:

B4X:

Multitouch.Initialize(B4XPages.MainPage, Array(PanelForTouch, Panel1))

Have you done both?
