my script : public class Move : MonoBehaviour {

public CharacterController CC;

public Animator Ani;

float MoveSpeed;
float TurnSpeed;

Vector3 V3;

// Use this for initialization
void Start () {

	MoveSpeed = 5f;
	TurnSpeed = 2f;

}

// Update is called once per frame
void Update () {

	V3 = new Vector3 (0, Input.GetAxis ("Mouse X"), 0);

	transform.Rotate (V3 * TurnSpeed); 

	Ani.SetBool ("walk", false);

	if (Input.GetKey (KeyCode.W)) {

		CC.Move(transform.forward * MoveSpeed * Time.deltaTime);
		Ani.SetBool ("walk", true);

	}

	if (Input.GetKey (KeyCode.A)) {
		
		CC.Move(transform.right * -1f * MoveSpeed * Time.deltaTime);
		Ani.SetBool ("walk", true);

	}

	if (Input.GetKey (KeyCode.S)) {
		
		CC.Move(transform.forward * -1f * MoveSpeed * Time.deltaTime);
		Ani.SetBool ("walk", true);

	}

	if (Input.GetKey (KeyCode.D)) {
		
		CC.Move(transform.right * MoveSpeed * Time.deltaTime);
		Ani.SetBool ("walk", true);

	}

}

}

UnassignedReferenceException: The variable Ani of Move has not been assigned.
You probably need to assign the Ani variable of the Move script in the inspector.
UnityEngine.Animator.SetBool (System.String name, Boolean value) (at C:/buildslave/unity/build/artifacts/generated/common/modules/AnimatorBindings.gen.cs:270)

Anytime a variable is public, you will be able to see it in the inspector
