NullReferenceObject problem

Object reference not set to an instance of an object

This statement holds the clue: playerRigidBody.MovePosition(transform.position + movement);

I am still trying to figure this out. removed all mesh and other placed objects.

using UnityEngine;
using System.Collections;

public class CharacterMovement : MonoBehaviour

{
public float speed = 6f;
public float turnSpeed = 60f;
public float turnSmoothing = 15f;

private Vector3 movement;		//x,y,z movement
private Vector3 turning;		//x,y,z, turning
private Animator anim;			//Animator variable
private Rigidbody playerRigidBody;		//Game objects act under control of physics

void awake()
{
	//Get references
	playerRigidBody = GetComponent<Rigidbody>();
	anim = GetComponent<Animator>();

}

void FixedUpdate()
{
	//Store Input Axis
	float lh = Input.GetAxisRaw ("Horizontal");
	float lv = Input.GetAxisRaw ("Vertical");
	
	Move (lh, lv);
	Animating (lh, lv);

}
void Move (float lh, float lv)
{
	//Move the Player
	movement.Set (lh, 0f, lv);
	movement = movement.normalized * speed * Time.deltaTime;
	playerRigidBody.MovePosition(transform.position + movement);

	if (lh != 0f || lv != 0f) 

	{
		Rotating (lh, lv);
	}
}

void Rotating(float lh, float lv)
	
{
	Vector3 targetDirection = new Vector3 (lh, 0f, lv);
	Quaternion targetRotation = Quaternion.LookRotation (targetDirection, Vector3.up);
	Quaternion newRotation = Quaternion.Lerp (GetComponent <Rigidbody>().rotation, targetRotation, turnSmoothing * Time.deltaTime); 
	GetComponent<Rigidbody>(). MoveRotation(newRotation);
}

void Animating (float lh, float lv)
	
{
	bool running = lh != 0f || lv != 0f;
	anim.SetBool ("IsRunning", running);
}

}

You have a typo. It’s Awake() not awake(). Capital A.
