My NavMeshAgent isn't working???

Here is my code

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class BirdMovement : MonoBehaviour {

private Transform target;
private NavMeshAgent birdAgent;
private Animator birdAnimator;
// Use this for initialization
void Start () {
    birdAgent = GetComponent<NavMeshAgent>();
    birdAnimator = GetComnponent<Animator>();


// Update is called once per frame
void Update () {
    //Set the bird's destination

    //Measure the magnitude of the NavMeshAgent's velocity
    float speed = birdAgent.velocity.magnitude;
    //Pass the velocity to the animator component
    birdAnimator.SetFloat("Speed", speed);


for some reason I'm getting this error message in my console Assets/Scripts/BirdMovement.cs(9,13): error CS0246: The type or namespace name NavMeshAgent' could not be found. Are you missingUnityEngine.AI' using directive?

Thus, I am not receiving a drop box for Target in the Bird Movement component where I am supposed to drop the player so the bird chases the player.

Any ideas???

I added UnityEngine.AI in the top to fix it. I got another problem though now which I will make a new question for.

May be its this one because i fixed the above one i got an another problem of this kind: Assets/Scripts/BirdMovement.cs(36,19): error CS1061: Type UnityEngine.AI.NavMeshAgent' does not contain a definition forSetFloat' and no extension method SetFloat' of typeUnityEngine.AI.NavMeshAgent' could be found. Are you missing an assembly reference?

Yep! It isn't in the video to bring in the UnityEngine.AI. Looks like this needs an update!
