Android Question How do you know where in a button/panel you have clicked?

[vecino]

Hi, I have a button (can be a panel or an image), and clicking on the left part diagonally does one thing.
If the right part is pressed diagonally it does something else.
How can I control it?
Thank you very much.

How can I control it?

With the touch event of the panel and the x coordinates.

Private Sub MyNicePanel_Touch (Action As Int, X As Float, Y As Float)
    
    If Action = MyNicePanel.TOUCH_ACTION_UP Then
        
        If x < MyNicePanel.Width/2 Then
            Log("Clicked on the left side")
        Else
            Log("Clicked on the right side")
        End If
        
    End If
    
End Sub

Hi, thanks for your help, although I think it is no good, because if you click from the middle of the button downwards, on the right side, then it will think that you have clicked on the left side.
Notice that it is diagonal, as if it were two triangles.

I know, i gave you a very simple example. Now you know how you can do this. In your case you need to check the x and y value, to find out which diagonal page was clicked on

I'll think about it, see what I can come up with.

With some corrections (orientation, left position, etc.) it can be a simple condition (assumption square button)

Private Sub MyNicePanel_Touch (Action As Int, X As Float, Y As Float)
   
    If Action = MyNicePanel.TOUCH_ACTION_UP Then
       
        If y > x Then
            Log("Clicked on the left side")
        Else
            Log("Clicked on the right side")
        End If
       
    End If
   
End Sub

Thank you very much, it works perfectly.
And also in a very simple way, I was trying to make calculations by measuring the hypotenuse and... I was breaking my head.

This should work if the panel is not square . . .

        If ((MyNicePanel.Width - X) / MyNicePanel.Width) > (Y / MyNicePanel.Height) Then
            Log("Clicked on the left side")
        Else
            Log("Clicked on the right side")
        End If

Edit : OOPS! Might have put the inequality the wrong way!

Oh, it doesn't work well

Now it is working properly.
Thank you very much, friends.
