Behavior Designer Pro brings AAA-quality behavior trees to Unity, supercharged with the performance of the DOTS architecture. Whether you’re working with GameObjects or Entities, in 2D or 3D, Behavior Designer Pro lets you design lifelike AI agents across any genre – no DOTS experience required.
 
🧠Why Behavior Trees?
Used by AAA studios, behaviour trees provide a clear, modular way to define complex AI decision-making. Behavior trees are perfect for everything from enemy combatants and NPCs to boss fights and ambient wildlife.
💡Use Cases
  • Enemy AI: Patrol, chase, flee, or coordinate group attacks
  • Companion AI: Follow, assist, or interact with the player
  • Crowd Simulation: Handle large-scale agent behaviors
  • Resource Management: Gather, manage, or defend game resources
  • World Interaction: Make NPCs, traps, or world items context-aware
  • Simulation Systems: Model animals, crowds, or village behaviors
  • Survival AI: Hunt, flee, or seek shelter dynamically
  • Stealth and Tactical Combat: Intelligent strategic behavior
  • Custom AI Behaviors: Create unique, project-specific behaviors
Whether you’re a programmer or designer, Behavior Designer Pro gives you the tools to create scalable, maintainable, and highly performant AI all inside Unity.
