Hi,  
I’m building an application with a dynamic number of boats  
that move randomly around the stage. The boats are viewed  
from the side. The depth of the boats is determined by the  
y position; so the one with the highest y position is  
‘in front’ of the others.

I loop through all the boats with a ‘for in’ loop and use  
the swapDepths function to set the y value of the boat as  
the depth.

When I play the movie some boats are flickering… Could this  
be because the boats have the same y position and the script  
gets ‘confused’? Or is it something else?

Does anyone has a solution?
