MOB Line Of Sight

[fathernitwit]

Hello,

So it is officially bothering me that mobs come flying through the ceiling in dungeons... so im going to take a look at fixing it..

what is the current status of whatever exists?
Is there pathfinding and/or LOS code allready somewhere? was there old map-reading crap somewhere? or is it all basically non-existent at this time?

Does anybody have ideas on how they were thinking of implementing it?

Any information would be greatly appriciated, hopefully it will save me some time and make me more productive
