Howdy,
First off i want to say that this was a much more thorough explanation of my issue before my login session expired and i had to come back here and type it again <img src="smileys/smiley7.gif" border="0" align="middle" />.
So my issue is that I am trying to have the player build a dynamic bridge from one island to another, as the bridge is built i want the sprite to search for a path from one island to the other treating the tiled background beneath like a solid obstacle and only crossing bridge pieces placed over the bridge, and their z-index was higher than the backgrounds. The issue is that the tiled background stops the sprite from moving at all.
-edit
I have gone ahead and attempted to include a picture as an example of what I am talking about below.

Any help would be Greatly appreciated, Thanks.
