How do I create an AI with Pathfinding?

Hi.

I want to create an AI system for the enemy (flying drone) but I don't know how to create the logic and how to use the events properly for this.

What I am trying to do is have every enemy patrol from a flag to another in a state called "patrolState".

If the player is in the LOS of the enemy I want to chase him and when is closer to him, shoot ("chasingState").

Some help would be much appreciated.

I've started to create this here:

dropbox.com/s/rt04r57r7u25i0i/AI%20top%20down%20example.capx

dop2000 Is it possible to make the enemy shoot, too ?

I've tried something here but it doesn't work.

dropbox.com/s/2xqqrwp7ii14lk4/AI%20top%20down%20example1%20with%20Shooting.capx

I've bookmarked the events where I added the "shootingState"

For some reason if I have 2 or more enemies that are chasing me, only one of them is shooting at me. I've tested with "for each", "pick by UID" but with no results.

"Trigger once" is a tricky condition, I suggest never using it in situations like this where multiple instances of objects are involved. It can cause all kinds of weird and hard-to-find bugs.
