Unity NavMesh (AI Navigation)

Give NPCs pathfinding in Unity 6.3 LTS: bake walkable surfaces and move agents around obstacles.
Targets Unity 6.3 LTS (6000.3) with the AI Navigation package 2.x.

Version trap (Unity 2022+/6): the old built-in Navigation window (Object/Bake tabs)
is gone. Baking is now component-based via the AI Navigation package
(com.unity.ai.navigation): add a NavMeshSurface to your level geometry and click
Bake. The runtime NavMeshAgent/NavMesh API stays in built-in UnityEngine.AI.

When to use

Use when an agent needs to walk/chase/patrol to a target, when baking a navigable surface,
adding dynamic blockers (NavMeshObstacle), or checking whether a destination is reachable.

Use when the project has the AI Navigation package, a NavMeshSurface component, or scripts
using UnityEngine.AI.NavMeshAgent.
