Weird monster behaviour

[MrCookieh]

so it's normal that the monster behaves like an idiot?
(I once made a monster, with only one pathnode, at the other side of a wall. The monster walked the whole time against a wall, although there was a door some metres next to him... so I think I have to live with that AI...)

Anyways, that's not that bad, but how about the patroling thing?

Now a second question: How can I make my monster patrol, so it doesn't disappear when it reached its last pathnode? It should go all pathnodes back to his starting point, and then starts over. This all the time.
