Overview

Adaptive Pathfinding System 2.0 is an advanced navigation plugin for Unreal Engine that introduces smooth, adaptive, and realistic AI pathfinding.

It fully supports 3D environments, multi-level navigation meshes, and provides built-in visualization and debugging tools.

The system generates curved (arc-based) paths controlled by parameters such as curvature and quality, allowing for fine-tuned movement behaviors.

APS 2.0 works seamlessly in both top-down and 3D projects — from simple RTS-style navigation to complex multi-layered environments.

Setting Up APS Navigation

Step 1: Configuring Navigation Data

⚙️ Step 1 – Configuring Navigation Data

1. Open Project Settings → Navigation System → Agents.

2. Add two agents:

   • 🟢 Agent 1 (APS) — set Nav Data Class to APS_NavigationData.

   • ⚪ Agent 2 (Standard) — set Nav Data Class to RecastNavMesh (the default UE navigation).

     

3. Adjust Agent Radius and Height as needed for each type.

4. Save and rebuild navigation.

🧩 Why two agents?

Keeping both agents allows you to:

• Use APS only for selected AI characters.
• Instantly switch between standard and adaptive navigation.
• Maintain backward compatibility with older blueprints or systems.

💡 To make a specific AI use APS, set its Preferred Nav Data to APS_NavigationData (see Step 3).
