This project implements a LabVIEW verision of Behaviour Trees.
The purpose of a Behavour Tree is to program large scalable decision logic where a State Machine can get very hard to follow and understand.

Behaviour Tree's were originally developed by the computer game developers Epic Games to be used in their Unreal Engine to program the AI for the Non Playable Characters (NPC's).

And other game developers developed a version of it as well

It has also found a use in Robotics and Drone control

And some research paper also discuss its use

The advantages of doing a behaviour tree in LabVIEW is the implemented diagram is the same as the behaviour tree's tree diagram (just rotated 90deg) and so it is far easier to follow the logic flow and an editor isn't required

Examples are included
