I will have one Image/Panel at left, and 3 Images/Panels at Right.
A child has to Drag and Drop the left image to a correct right image, if he drop onto a correct image, i'll show some message for example, and if it is not correct, i´ll send image to original position !
I'm using it. How can i detect if one panel/view is on top of other one ? I need to check it. I can detect comparing X and Y on Panel1_Touch , but if i use this way to check , a child has to put the panel exacly on top, same X and Y, and it will be very difficult ! If there is some way to detect that one panel is on top of another, will be perfect , something like docking areas !
You will need to implement it. The exact details depend on your requirements.
Something like:
B4X:
Sub DoTheyOverlap(v1 As View, v2 As View) As Boolean
'c = center
Dim cx1 As Float = v1.Left + v1.Width / 2
Dim cy1 As Float = v1.Top + v1.Height / 2
Dim cx2 As Float = v2.Left + v2.Width / 2
Dim cy2 As Float = v2.Top + v2.Height / 2
Return Abs(cx2 - cx1) < v1.Width / 2 + v2.Width / 2 And Abs(cy2 - cy1) < v1.Height / 2 + v2.Height / 2
End Sub
