Do you want avoid triggering an object that is on the top layer if you swipe across it whilst scrolling ? If so, this may work (although there could well be a more straightforward solution):
Add all the objects on the non-scrolling layer to a family .
Add a global variable "isScroll" set to 0.
On touch start:
if is NOT touching family: set isScroll to 1.
On touch family:
if isScroll = 0
if object A do X
if object B do Y etc
On touch end: set isScroll to 0
