Get TouchIDs on different sides of the screen

Based on this thread here: http://www.scirra.com/FORUM/topic66471.html.

I'm trying to make it so that a different touch ID is assigned depending on where the user touches the screen. I have two large invisible sprites that each cover half the screen. You can see one of them here:

Does anyone know how to get a different touch ID based on where the user touches the screen?

CAPX File

Do you just want to get if the player clicked on the left or the right side ? Or what do you try to do with the touch.Id

You can do it 2 different ways.

Either add another condition that checks if the touch is over the "left side screen box" or the right side screen box at the time of touch.

or check its X position of the touch, and see if that's greater or less than half of the layout width.
