Introduction

Brainiac is a behaviour tree implementation for Unity3D that features an intuitive, node-based visual editor.

A behaviour tree is a tree of hierarchical nodes that control the flow of decision making of an AI entity. At the extents of the tree are the actual commands that control the AI entity, and forming the branches are various types of utility nodes that control the AI’s walk down the trees to reach the sequences of commands best suited to the situation.

You can find more information about behaviour trees here.
