Animation issue

So I’m trying to learn ow to animate a character for use. After trying to assign “IsJumping” to “Jump” how ever it comes up with this error. “NullReferenceException: Object reference not set to to an instance of an object AnimationController.Update() (at Assets/AnimationController .cs:17)”.

Here is the code. As stated in the error the line in question is line 17.

using UnityEngine;
using System.Collections;

public class AnimationController : MonoBehaviour {

static Animator animator;

void start ()
{
    animator = GetComponent<Animator>();
}

void Update ()
{
    if(Input.GetButtonDown("Jump"))
    {
        animator.SetTrigger("IsJumping");
    }
}

}

In your animator are you sure you have that Trigger: “IsJumping” spelled exactly the same?

Also, you can just declare your animator by

Animator animator;

If this doesn’t work, notify me and I will tell you how to make a bool instead.

Yes, every character is exactly the same, I also switched the declaration to what you suggested, neither worked.
