Behavior trees plus hierarchical state machines for Godot 4, shipped as a GDExtension with a dedicated editor panel and its own debugger. The combination is the point: a state machine handles coarse modes such as patrol, combat, and flee, while a behavior tree handles the decision detail inside each mode. Heavier to install than a pure GDScript addon, and faster at runtime because the core is compiled.
- Distributed as a GDExtension binary per platform, or as a custom Godot build; the binary set must cover every export target you ship, including web if you need it
- Blackboard variables are typed and scoped per tree, which avoids the shared-global-dictionary pattern that makes hand-rolled trees fragile
- Tasks can be written in GDScript or C++; GDScript tasks are the normal path and hot-reload during play
- Ships a behavior tree debugger panel that shows live task status, worth the install cost on its own for a project with many enemy types
