This came to me as I was helping someone to create a programme (script) to search the map for a particular item. It seems to me, when searching a large area, that being able to specify the exact ObjType when searching would reduce the amount of memory used by the created array. So here is my proposed function:

That is a great idea Kiko. I do not even remember how many times that function would made my life easier

This would be a good, would make things a lot easier for doing certain things and can already think of at least one use for a function such as this.
