Couldn't think of a good description for this, but I imagine it comes up fairly often and there's a solution, but my brain isn't working today and I'm not sure what to search for in the forums.
I have a situation where I need to check through a bunch of tiles, and if they meet a certain condition, they spread that condition to neighbouring tiles.
So I'm doing....
Tile > Has condition.
Neighbouring tile > Apply condition.
The problem is that once I need to do this in a single pass, so that ALL tiles in the initial pick will spread the condition (but not the new ones). So when I find the neighbouring tile, I lose my list of picked objects from the above event - it just reduces it down to the single tile. So that puts an end to the event.
As I say, I'm sure there's a better way of doing this, but what I basically need to do is to retain my list of picked objects from the top event while still somehow picking a single object of that type in the subevent.
