Unity AI Guide: Create a Autonomous Game with Adaptive NPCs from Udemy

Unlock the potential of Artificial Intelligence in Unity by mastering Behavior Trees in this hands-on, practical course. Together, we’ll build a fully autonomous "Hide and Seek" game with Adaptive AI that learns and evolves.

Designed for beginner and intermediate game developers and designers with a passion for AI, this step-by-step course will guide you from the basics to advanced techniques.

We'll begin by exploring the fundamentals of Behavior Trees using the Behavior Designer plugin for Unity, setting a solid foundation. Then, we'll get our hands dirty by building simple AI examples to understand core concepts. From there, we’ll dive deep into the advanced area by creating our fully autonomous "Hide and Seek" game, where AI-driven characters will strategize and adapt without any player input. To enhance the gameplay experience, we'll create a UI that displays stats and information, making it easier to analyse AI behaviour. Finally, we'll take things to the next level by implementing AI adaptation, allowing our agents to learn from their experiences and adjust their behaviour dynamically using database techniques similar to machine learning.

This course includes a demo version of Behavior Designer, ensuring you have all the tools you need to succeed. Plus, you'll enjoy lifetime access to the course, allowing you to learn at your own pace and revisit the material whenever you need.

Join us on this exciting journey and take your AI development skills to new heights.
