noplayeronwall
 

If you use the noplayeronwall command, then use move; with the "wall checking" option set, it will skip over "walls" SERVERSIDE, but not clientside.

I had an NPC moving via move; after using noplayeronwall. I then stepped in its path. It stopped moving on my screen, but I sat there and waited. The NPC eventually reached its destination and stopped (serverside). When it stopped, the NPC on my screen jumped from sitting in front of me to where it had stopped serverside. Noplayeronwall is apparently not sent to the client. I'm not sure if that was intentional or not, but if it WAS, I'd like to have a noplayeronwall2 or something that IS sent to players.
