Custom Mob Behavior (Walking within specific Regions)

I basically want to spawn a custom mobs that will act like normal mobs (zombies/skeletons), but stay within a specific region. I've been looking at related tutorials, but I'm still a little lost on how I should go about doing this.

I've looked at:

(hopefully one of you can help!)

I would like to use kumpelblase2's api if needed, but on the other hand, I don't know how often his api will be updated and I don't want things to break. If someone can guide me in the right direction, I would appreciate it!

 

I don't know which part you are having trouble with exactly but you need to put a check in where the mobs move making sure the to location is inside the region, if it is reverse the direction or something.

 

Would I do this by setting up a onEntityMove custom event, or would I put the check into a custom Pathfinding?

 

That would be up to you I guess, the event would be called a huge number of times though so it might be an idea to avoid that.

 

I think the best thing you can do is customize the strolling. Extend the random stroll pathfinder. Override the method where it generates the coordinates. Let it generate a new set of coordinates if the target coordinate is outside the bounding box of the area and boom your done.

 

Thanks. THatd what I did. Also how does the priority system work? Do lower priorities get executed more often?

 

I think it works like this:
It starts with the ones from priority 1. If none of them claimed the walking system by returning true (as seen in my tutorial), it'll go to the second one. When a pathfindergoal returns true, It'll ignore all the other goals.
