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

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

1. Add the Surface component to your scene.
2. Configure the grid size and node radius.
3. Assign obstacle layers using Unity colliders.
4. Implement the IUnit interface for your agent.
5. Register the agent with the surface to begin pathfinding.

The system will automatically process path requests using parallel Burst jobs.

  Collections

Optional:

• Cysharp UniTask (used in example workflows but not required)

Limitations
