[Opensim-users] osNPCSit behavior ... a comment/question

[Justin Clark-Casey]

I tested this and the NPC code does what I would expect.  If the prim is <= 10 meters without a sit target then sit is 
immediate.  If the prim is >10m away and has no sit target then nothing happens.  This mimics behaviour for an avatar, 
though I think there is a good argument that it should be ignored for NPCs (sit should be possible from any location).

I suspect the behaviour you're seeing is from an older version of OpenSimulator (probably pre 0.7.5) where the same 
thing would be attempted for ordinary sit attempts by users.
