A.I. Behavior Tree Structure

I'm trying to create a very simple behavior tree for my AI and I'm having trouble figuring out a straight forward way of structuring it within Unity using the component system. I can't think of any other way to do it besides making Nodes (like Sequence, Selector, etc.) components and creating the actual tree using a hierarchy of GameObjects on the Enemies... if that makes any sense at all... This approach seems really sloppy and bloated to me... Does anyone have any other ideas on how to set something like this up within Unity?

Also, I've tried a few Asset Store packages but they severely lack documentation so I think I'm on my own with this one.

 

Behaviours ? What about a finite state machine ? Unless I'm misunderstanding what you are trying to achieve.

You can create C# classes/structs that don't derive from MonoBehavior so you're free to create whatever data structure you want...

You'll end up with a reference to the structure in a MonoBehavior since that's how unity works but beside that you're free to do as you fancy (except with threads, there you're limited to only using your own code)

 

You should check out this thread. There are some interesting behavior tree solutions and some code I uploaded. You might wanna take a look at that as you are mentioning something similar in your post.
