MindWineBT

🧠 Behaviour Tree System for Unity 2022.3

A modular, extensible Behaviour Tree framework for game AI — designed for clarity, flexibility, and performance.

🎯 Features

• ✅ Node-based architecture (Selector, Sequence, Decorators, etc.)
• 🧩 Custom actions and conditions
• 🔁 Support for composite, decorator, and leaf nodes
• 📦 Serialized and runtime trees
• 🛠️ Editor-friendly
• 📄 Easy-to-read and debug

📚 Overview

Behaviour Trees are a structured way to create complex, reactive AI. This system allows developers to create intelligent agents by composing nodes like:

• Composite Nodes: Sequence, Selector
• Decorator Nodes: Inverter, Repeater, Timeout
• Leaf Nodes: Action, Condition

Example of a simple tree:

Selector
├── Sequence
│   ├── Condition: HasTarget
│   └── Action: MoveToTarget
└── Action: Patrol

🚀 Getting Started

🔧 Installation
