BTScript

A text-based behaviour script language for Unity.

Motivation

The project is created in frustration that current Unity behaviour tree plugins (e.g. Behaviour Designer) is overly complex and feels strange to work with. As a programmer, I prefer a text based rather than dragging long branches of nodes.

Main features:

1. Simple script language syntax
2. Extensible (can easily create custom nodes)
3. Workflow is flexible and simple

Installation

Clone the repository and copy the Assets/Plugins/BTScript folder into your project's same directory.
