Challenge 2: NavMesh target

Write a script that calls NavMeshAgent.SetDestination.

Challenge 2: Setting NavMesh Destination

To enable AI characters to pathfind across 3D scenes, the NavMeshAgent component is utilized. Invoking SetDestination directs the agent toward the target position.

using UnityEngine.AI;

NavMeshAgent agent = GetComponent<NavMeshAgent>();
agent.SetDestination(targetPosition);

The agent automatically computes the optimal route, steering cleanly around obstacles.

Exercise NavMesh destination assignment test

Define a Start method. Inside, declare string hedefAdi = "HedefNoktasi"; and print "Hedefe yonelindi: " + hedefAdi to the console.

Show example solution

using UnityEngine;

public class NavDestinationTester : MonoBehaviour
{
    void Start()
    {
        string hedefAdi = "HedefNoktasi";
        Debug.Log("Hedefe yonelindi: " + hedefAdi);
    }
}

Exercise Agent stopping distance check

Define a Start method. Inside, declare float durmaMesafesi = 1.5f; and print "Durma mesafesi: " + durmaMesafesi to the console.

Show example solution

using UnityEngine;

public class NavStoppingTester : MonoBehaviour
{
    void Start()
    {
        float durmaMesafesi = 1.5f;
        Debug.Log("Durma mesafesi: " + durmaMesafesi);
    }
}

Test yourself

Which method must be called to direct a NavMeshAgent toward an objective?
- agent.JumpToNav()
- agent.BakePath()
- agent.RunImmediately()
- agent.SetDestination()
Show answer

agent.SetDestination() — In NavMeshAgent, the method that resolves the path and begins locomotion is SetDestination.

Include navigation namespace

using UnityEngine.____; public class EnemyAI : MonoBehaviour { }

Show answer

using UnityEngine.AI; public class EnemyAI : MonoBehaviour { }

NavMesh elements

NavMeshAgent

NavMesh pathfinding movement component
SetDestination

Sets target coordinate and starts path
remainingDistance

Current remaining distance to target
stoppingDistance
