When writing script logic or inspecting the scene hierarchy, what base class does the root BeehaveTree node extend?

Addon: Beehave · version
v2.9.2· Godot 4.1+ · MIT · source: https://github.com/bitbrain/beehave · written in GDScript (no official C# API — this skill is GDScript-only by design).
| Approach | Best for |
|---|---|
Core-engine FSM (state-machine skill) | Simple agents, < 5 states, no addon |
| Beehave (GDScript addon) | Lightweight BT, GDScript-only projects, fast iteration |
| LimboAI | BT and HSM together, visual editor, C++ performance, C# support (module build) |
Choose Beehave when your project is GDScript-only, you want a behavior tree without a custom engine build, and you value a simple node-in-scene-tree authoring workflow. Beehave trees live entirely in the scene tree — every composite, decorator, and leaf is a regular Node child. For a heavier C++/C# solution with HSM integration, use the limboai skill instead. For plain state machines without a BT, use the built-in state-machine skill.
C# note: Beehave has no official C# API (zero .cs files in addons/beehave/). From C# you can call the GDScript API via Godot cross-language interop (GetNode<Node>(...).Call("tick", actor, blackboard)), but Beehave provides no typed C# classes.
addons/beehave/ folder from the GitHub release into res://addons/beehave/.BeehaveGlobalMetrics and BeehaveGlobalDebugger.script_templates/ from the addon into the project root for leaf scaffolding templates.A Beehave tree is built from three kinds of nodes, all placed as regular scene-tree children:
| Role | Node | Behavior |
|---|---|---|
| Tree root | BeehaveTree | Ticks the child every frame (or physics/manual); extends Node (not BeehaveNode) |
| Composites | SequenceComposite, SelectorComposite, SimpleParallelComposite, … | Flow control — AND / OR / parallel logic |
