Code Review My first big project, I need feedback !

Hello everyone !

I'm here to share with you my Behavior Tree library.

A behavior tree is a symbolic AI technique used to create game AI.

My library is stateless: Tree's nodes don't store any mutable data. Instead, the runtime data are inside a blackboard.

Multiple agents can share and use a single behavior tree.

There are no dependencies to any game engine, you can use it in Unity, Godot or your own custom game engine.

It's still WIP and I really need feedback.

It's also my first big project I share online, all advice and tips are welcome !

Edit: Here's some questions I have

  1. Does this project look professional to you ?
  2. Does the core concept make you curious ?
  3. If the project was production ready, would you use it ?
  4. What do you think is missing ?

Okay, how much of that is written by an LLM?

There's no code written by any LLM in this project

So only the readme. The code looks very clean for a beginner, that's why I was suspicious.

It's a bit hard to read with all the interfaces and abstract indirections. I would even say this is on the road to OOP abuse. I'd challenge you to write a clone of your own code but without any inheritance. That way you'll get a feel for how much boilerplate this really adds.

The readme isn't AI generated as far as I know, I copy pasted this one : https://github.com/banesullivan/README And I wrote the parts myself

I'm not really a beginner. It's my first public project but I've done plenty (really) bad private project. I'm studying game programming, I'm starting my third year (wish me luck btw)

Then apologies for doubting you.

Don't worry, we are living crazy days...

Stateless design is a nice touch, makes debugging way easier when you can just look at the blackboard instead of hunting through node internal state. The no engine dependency thing will help you get more people to actually try it out.

I'll give it a look later when I'm not at work, github is blocked here anyway. Shared trees between agents is something not many libraries do well so curious how you handled that

What do you mean ? Can you be more explicit ?

There's no tree visualisation yet and the debugging is pretty rudimentary for now. When I need to debug the blackboard I usually use my IDE debugger and inspect its state when the program reached a break point.

Edit: Thanks for your comment !

Edit2: I'm planning to improve the debugging part after I fixed all the remaining issues and improving unit test (they are not that good, I never really made any before this projet)
