Game AI techniques as small, readable Godot 4 addons, written to be studied as much as used. Each technique is its own folder under addons/: A* and pathfinding, minimax and MCTS, behaviour trees, GOAP and PDDL planning, utility AI, fuzzy control, steering, perception and belief, team tactics, bandits, an opponent model, constraint solving, and a validator for local LLM replies.

ai_core holds the shared grid and interfaces; six techniques need it, the rest stand alone. Untick any folder you don't want in the install dialog.

Every addon opens with a header saying what it solves, its cost, and when not to use it. The repository also has playable demos and a Python twin of each technique (pip install gameaikit).
