What does surface.find_entities_filtered return if it didn't find anything? I'm trying to check if a search area contains any entities of type="resource", and checking if the returned table ~= nil didn't work.

Please let me know if there's more info I can add. I've attached the mod, sorry if it seems messy. The place I'm having trouble with is around line 74 of the control.lua.

*Edit: Added [Solved] to subject.*

It seems to return an empty table.

Thanks. Your info and a quick google search solved my problem I'm now doing something like: I got the advice here: http://stackoverflow.com/questions/1252 ... no-entries

That was the last piece of code that needed to work to make the one feature of my mod. I might post in the WIP forum with what I've got, even though it's ugly in so many ways.

Edit: (This is solved, can I change the thread title to add [solved] to it?)
