# Navigation Mesh Skill Comprehensive navigation mesh generation and pathfinding implementation for game AI systems across multiple engines. ## Overview This skill provides capabilities for creating, configuring, and utilizing navigation meshes for AI pathfinding. It covers navmesh generation, agent configuration, dynamic obstacles, off-mesh links, and runtime navigation queries. ## Capabilities ### NavMesh Generation - Configure navmesh build settings - Define walkable areas and surfaces - Set up area types with costs - Generate runtime navmeshes ### Agent Configuration - Configure agent radius and height - Set movement parameters - Define avoidance priorities - Configure step height and slopes ### Pathfinding - Query paths between points - Handle partial paths - Implement path smoothing - Support hierarchical pathfinding ### Dynamic Navigation - Handle dynamic obstacles - Implement navmesh carving - Update navmesh at runtime - Handle moving platforms ### Off-Mesh Links - Create jump links - Configure drop connections - Handle ladders and teleports - Set up one-way paths ## Prerequisites ### Unity ```csharp // Built-in: Package Manager > AI Navigation // Install: com.unity.ai.navigation ``` ### Unreal Engine ```cpp // Enable NavigationSystem module in Build.cs PublicDependencyModuleNames.AddRange(new string[] { "NavigationSystem", "AIModule" }); ``` ### Godot ``` # Enable NavigationServer2D/3D in project settings # Use NavigationRegion2D/3D and Navigatio...
