Behavior Designer Pro - DOTS Powered Behavior Trees

Behavior trees are a proven AI technique used by AAA studios to create lifelike, scalable decision-making systems. Behavior Designer Pro brings that same approach into the future with a modern, data-oriented architecture built on Unity DOTS.

Behavior Designer Pro works with GameObjects or Entities, allowing you to choose the workflow that best fits your project. You can adopt DOTS gradually, mix architectures, or use a fully data-oriented setup all while authoring behavior trees visually inside Unity.

By leveraging DOTS for efficient data layout and processing, Behavior Designer Pro reduces the overhead of AI systems and ensures performance remains consistent and predictable as your project scales. These performance gains are noticeable even with a small number of agents, freeing up resources for other aspects of your project.

No DOTS experience is required.
