gale.ai package

gale.ai: a modular toolkit to build autonomous characters — Kinematic bodies and steering behaviors, a behavior tree, a decision tree, a shared Blackboard, generic graphs with search algorithms, the Agent class that ties them together, a vision-cone Perception system, and a minimax search with alpha-beta pruning for turn-based adversarial decisions.

See docs/examples/gale_ai.rst for a walkthrough.
