Please note that the sample you provided is not quite correct. I assume you wanted something like this:

Thank you! Quite right, the Printf was busted, execution just never reached it :o

PlayerPawn p = players[consoleplayer].mo;
BlockLinesIterator bli = BlockLinesIterator.Create(p, 64);
while ( bli.Next() )
{
   Console.Printf("%f", bli.CurLine.v1.p.x);
}

I would presume that someone could make a simple pull request to supersede the errors.

Graf confirmed there was a simple typo (constructors return a BlockThingsIterator) in zscript/base.txt, but fixing that exposed another problem whose fix is less obvious to me. Let me know if my example code from that post is doing something wrong beyond the bugged behavior.
