Yes, exactly, many thanks, that was very helpful. It's getting more complicated to understand though with these expressions :P
Do you have any idea if it would be easy to make so that every object that is "picked", also keeps checking in their 8 directions?
For instance:
<img src="http://i.imgur.com/63o3r.png" border="0" />
The objects in that chain should get all picked in one click because they keep overlapping each other in a chain.
