Is This Quest For You?

Perfect for you if:

  • You want enemies that feel intelligent, not just chase-and-attack bots
  • You understand basic GDScript and want to level up your architecture
  • You're building a 3D action game and need proper AI systems
  • You want code you can extend without rewriting everything

Not for you if:

  • You've never opened Godot or written GDScript before
  • You're looking for 2D AI (this is specifically for 3D CharacterBody3D)
  • You want behavior trees or utility AI (this is state machines)
  • You need boss AI with phases (that's an advanced topic)
