Unity AI Navigation

NPC movement should feel natural and believable.

Unity’s NavMesh system simplifies pathfinding.

What is NavMesh

NavMesh defines walkable areas for AI characters.

NPCs automatically navigate around obstacles.

Implementation Steps

Typical workflow includes:

1. Mark environment as Navigation Static
2. Bake NavMesh
3. Attach NavMeshAgent to NPC

Example script:

agent.SetDestination(target.position);

The AI calculates the path automatically.

Optimization Tips

Avoid frequent recalculations.

Use smart waypoint systems for large environments.

Final Thoughts

NavMesh allows developers to build intelligent NPC movement quickly.

Combine with behavior systems for advanced AI.
