SectorTagIterator

Iterates over sector indices with a specified tag.

class SectorTagIterator : Object
{
   static SectorTagIterator Create(int tag, Line defline = null);

   int Next();
   int NextCompat(bool compat, int secnum);
}

• Create

  Creates a new iterator over sectors with tag tag. TODO: I can't find where defline is actually used. It is a mystery.

• Next

  Returns the index of the current sector and advances the iterator. Returns -1 when the list is exhausted.

• NextCompat

  If compat is false, acts exactly as Next. Otherwise, returns the index of the current sector and advances the iterator in a manner compatible with Doom's stair builders.
