NavMeshAgent

Learn enemy movement with the NavMeshAgent component.

The NavMeshAgent Component

The NavMeshAgent component is attached to characters (enemies, NPCs, companions) intended to navigate the NavMesh. It handles path resolution, acceleration, and dynamic steering around obstacles.

using UnityEngine.AI;

public class EnemyMovement : MonoBehaviour {
    private NavMeshAgent agent;
    void Awake() {
        agent = GetComponent<NavMeshAgent>();
    }
}

Upon instantiation, the agent automatically snaps to the closest underlying NavMesh surface.

Agent Parameters and Obstacle Avoidance

The NavMeshAgent exposes critical movement controls: speed (maximum velocity), stoppingDistance (braking proximity to target), and radius (collision cylinder width).

agent.speed = 3.5f;
agent.stoppingDistance = 1.0f;

When agents meet, built-in Obstacle Avoidance routines steer them around one another instead of clipping through.

Exercise Agent speed configuration

Define a Start method. Inside, declare float hiz = 3.5f; and print "Agent hizi: " + hiz to the console using Debug.Log.

Show example solution

using UnityEngine;

public class AgentSpeedTester : MonoBehaviour
{
    void Start()
    {
        float hiz = 3.5f;
        Debug.Log("Agent hizi: " + hiz);
    }
}
