Godot plugin in Flockbay
LimboAI
LimboAI adds behaviour trees and state machines to Godot 4, and Flockbay puts it in your project for characters.
What it is
LimboAI is an open-source plugin for Godot 4 that combines behaviour trees with state machines, for building how characters decide what to do.
It comes as a GDExtension, which needs no custom engine build, or as a C++ module for people who build Godot themselves. Its repository says both stay compatible.

What Flockbay does with it
Flockbay copies LimboAI into your project so the AI can give characters behaviour trees and the shared memory those trees read, when a character needs more than a few simple states.
You can open and edit those trees in the Godot editor with LimboAI's own tools.
