Path Node Question

[amusei]

Hi guys,
I have a question about Path Nodes. So I have created a corridor with many turns and when you walk a little a monster will appear to chase you. I use ShowEnemyPlayerPosition. I know that if you are using AddEnemyPatrolNode it will disappear when it reaches the last Path Node and the player is not looking. But what if you aren't using it but you have laiyed down a lot Patrol Nodes so that the enemy won't try to walk through walls(there are a lot of turns) while chasing you . Also will he walk around or will he stay still when he loses you?
Thanks in advance
