With Classics scripted wall detection I have bitflags passed into the function to determine what checks should be made, be it wall tiles, blocking NPCs or players, the latter having further options such as whether it should include just the player themself, include just other players, include all players, ignore players with 100 ap, ignore players with the same Guild tag outside of Event levels or Spar Zones etc.

I'd imagine this would be extremely useful as a built-in function, i've found onwall to be somewhat problematic at times in the past.
