Behavior Designer Pro is the definitive behaviour tree solution for both your GameObject and Entity-based workflow.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.📚Documentation | 🎥Videos | 💬Discussions | 🌐Discord🏆 Industry RecognitionUnity Verified SolutionNominated 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.✨Key FeaturesPerformance & ArchitectureBuilt on Unity DOTS for efficient processing and memory accessSupports GameObjects, Hybrid, and Entities workflowsZero allocations after startupQuick execution with job system and Burst supportEfficient execution that scales smoothly with agent countAuthoring & ToolingVisual node-based behavior tree editorRealtime visual debugger with breakpointsRuntime state inspectionSave & Load supportBehavior DesignUtility Theory-based task evaluationConditional Aborts for dynamic responsesShared variables for inter-task communicationEvent-driven behavior supportExtensibilityFamiliar and flexible APICustom node and editor extensionsDesigned for long-term project integration💡Use CasesEnemy AI: Patrol, chase, flee, or coordinate group attacksCompanion AI: Follow, assist, or interact with the playerCrowd Simulation: Handle large-scale agent behaviorsResource Management: Gather, manage, or defend game resourcesWorld Interaction: Make NPCs, traps, or world items context-awareSimulation Systems: Model animals, crowds, or village behaviorsSurvival AI: Hunt, flee, or seek shelter dynamicallyStealth and Tactical Combat: Intelligent strategic behaviorCustom AI Behaviors: Create unique, project-specific behaviors🤝Seamless IntegrationsA* Pathfinding Project (with Movement Pack)Animal ControllerDialogue SystemDOTS SurvivorsFeelLove/HateCurvy SplinesPlayMakerQuest MachineSensor Toolkit 2Simple Waypoint SystemUltimate Character ControllerUltimate Inventory System📦Available Add-ons (Separate Purchase)Formations Pack: Intelligent navigation and dynamic group locomotionMovement Pack: Steering behaviors, pathfinding, cover, patrol, and moreTactical Pack: Group combat awareness and movementSenses Pack: Perception modules for sound, light, visibility, and moreBehavior Designer Pro represents the forward-looking evolution of behavior trees in Unity, combining proven AI design with steller performance and flexible workflows.🚀 Performance DrivenPowered by DOTS: Leverages the high-performance Data-Oriented Technology Stack (DOTS) architecture for optimized processing, with no DOTS knowledge required to use itBurst Compiler Support: Utilizes the Burst compiler for ultra-fast execution of performance-critical codeUses Unity Job System: Efficiently manages multi-threading to maximize performance across both GameObjects and Entities🎨 Modern Interface and FlexibilityBuilt with UIToolkit: Uses Unity's modern UIToolkit framework for a clean, responsive, and intuitive interfaceUniversal Render Pipeline (URP) & High Definition Render Pipeline (HDRP) Compatibility✅ Unity Version SupportSupports Unity 2022.3 to Unity 6Note: Due to ECS limitations, Behavior Designer Pro does not support WebGL.
