I been trying to modify a dragon to land on a roof top, then fly and orbit, then land again and repete this action

I have the dragon to where he in non agresive and flys around the area, but I can not figure out how to get him to perch

and then fly again.

Just need some pointers.

Thanks

It's been a long time since I did this, but... You need to link your dragon to the perch as a linked reference. And then there is a patrol data tab somewhere, where you can set the time the dragon will "patrol" at that particular roost. I don't remember if the patrol data gets set on the dragon reference or on the perch reference, but it should be available somewhere in there.
