Behavior Designer Pro 3 - DOTS Powered Behavior Trees

Build enemies that patrol, chase, retreat, and react to the world in 2D or 3D. Behavior Designer Pro helps you change decisions without rewriting an agent’s entire logic. Its DOTS runtime uses Burst and parallel jobs to keep tree evaluation efficient as agent counts grow.

Start with Your First Behavior Tree and the sample scenes, then adapt the logic to your game. Use familiar GameObjects with no prior DOTS experience, or choose Entities.

⚡Performance at the core

• Burst-compiled tree traversal for both GameObject and Entity workflows.
• Unity Job System execution that distributes traversal across worker threads and agents.
• A runtime designed to avoid heap allocations after initialization.
• Manual ticking and evaluation limits to control when decisions run and bound traversal work

🏆 Industry Recognition

• Unity Verified Solution
• Nominated for the 17th Annual Unity Awards

🧠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

✨Build and debug in one workflow

• Arrange actions, conditions, composites, and decorators in a visual editor.
• React to changing situations with conditional aborts.
• Inspect execution during Play Mode and use breakpoints to investigate behavior.
• Reuse behavior with subtrees and share data through variables.
• Use utility-based selection when choices should depend on scores.
• Use events to coordinate behavior and save or restore runtime state.
• Find configuration problems with realtime graph validation.
• Extend tasks and editor displays for your project’s own systems.
• Save runtime traversal with the Save/Load feature.
