PathFinderAI-[Volumetric-Voxel 3D/2DAstarNav]

Asset description

Description Pathfinding Agent is a high-performance pathfinding system for Unity designed to handle multiple AI agents efficiently using Unity's C# Job System, Burst Compiler, and Native Collections. The system supports both 2D and 3D grid-based navigation and allows developers to define custom traversal logic for different types of units such as characters that can walk, jump, climb, swim, crawl, or fly. Unlike traditional single-threaded pathfinding solutions, this package performs parallel path calculations across multiple agents, making it suitable for large simulations, strategy games, RTS games, and AI-heavy environments. The system is designed to be extensible and modular, allowing developers to integrate their own movement logic while using the provided high-performance pathfinding backend. Key Features High Performance Pathfinding Uses Unity C# Jobs + Burst Compiler for multi-threaded pathfinding. Optimized with NativeCollections for low memory overhead. Supports parallel pathfinding requests for multiple agents. Flexible Grid System Generic Grid architecture supporting both 2D and 3D navigation. Built-in world-to-grid conversion utilities. Efficient neighbor lookup and grid indexing. Customizable Agent Behaviour Agents integrate with the system by implementing the IUnit interface, allowing developers to define: Agent position and destination Movement capabilities (walk, jump, swim, fly, crawl, climb) Custom movement states Traversal costs and restrictions Transform synchronization with Unity objects Parallel Path Requests Multiple agents can request paths simultaneously using Burst-compiled jobs, making the system suitable for large numbers of AI units. Path Optimization Includes: Path retracing Path simplification Efficient node traversal Debugging Tools Includes Gizmo-based debugging tools for visualizing: Navigation nodes Generated paths Traversal logic These tools help quickly debug navigation behavior during development. How It Works Add the Surface component to your scene. Configure the grid size and node radius. Assign obstacle layers using Unity colliders. Implement the IUnit interface for your agent. Register the agent with the surface to begin pathfinding. The system will automatically process path requests using parallel Burst jobs. Included Systems Core navigation grid supporting 2D and 3D environments.Grid Manages the navigation grid and agent registration.Surface Component Defines how agents interact with the pathfinding system.IUnit Interface Burst-compatible data structure used internally by pathfinding jobs.UnitData Struct Handles A* pathfinding calculations.PathRequest Job Requirements Unity 2023.3 or newer (tested up to Unity 6.3) C# Jobs SystemUnity packages: Burst Collections Optional: Cysharp UniTask (used in example workflows but not required) Limitations While the destination is recalculated at runtime, the grid walkable areas and obstacle areas are only calculated once Suitable For RTS games Simulation games AI crowd systems Strategy games Large-scale NPC movement systems Support For questions or technical support: This asset does not include art assets or character controllers. Movement logic must be implemented by the user through the IUnit interface. Third-Party Content: This asset uses AI-generated textures created with Unity AI tools (Unity Muse).
