Can't get animator.SetInteger to work.

I'm trying to use Animator Controller component to transition from Idle animation to walking animation. I can't seem to get animator.SetInteger to work for me. I've tried it with and without the else statement. It works if I put it in the start funtion, but I need it to be tied to the walking input. Movement works fine and through the public float I can see the verticalInput changing when I press the key. Also everywhere I've looked and every video does it just like this with no problems.

No compiler errors, but Unity throws this error when I hit play: NullReferenceException: Object reference not set to an instance of an object.

Movement still works fine with play, just no animation unless I change the "Condition" parameter manually through the component.

I also tried Debug.Log(animator.GetInteger("Condition")), but I guess it doesn't work like that.

Here's my script:

Code (CSharp):

1. public class PlayerController : MonoBehaviour
2. {
3.     public float speed = 8;
4.     public float rotationalSpeed = 45;
5.  
6.     public float verticalInput;
7.     private float rotationalInput;
8.  
9.     private Animator animator;
10.  
11.  
12.     void Start()
13.     {
14.         Animator animator = GetComponent<Animator>();
15.         //animator.SetInteger("Condition", 1);
16.     }
17.  
18.     void Update()
19.     {
20.         verticalInput = Input.GetAxis("Vertical");
21.         rotationalInput = Input.GetAxis("Horizontal");
22.  
23.         transform.Translate(Vector3.forward * verticalInput * speed * Time.deltaTime);
24.         transform.Rotate(Vector3.up * rotationalInput * rotationalSpeed * Time.deltaTime);
25.  
26.      
27.         if (verticalInput != 0)
28.         {
29.             animator.SetInteger("Condition", 1);
30.         }
31.         else
32.         {
33.             animator.SetInteger("Condition", 0);
34.         }
35.      
36.     }
37. }

Any Ideas to what I'm doing wrong here?

 

It's because you are cashing the animator in a local variable. Drop the "Animator" on the line 14.
Like this:

animator = GetComponent<Animator>();
