i keep getting this error even though i copied the script exactly from the tutorial
using UnityEngine;
using System.Collections;
public class NewBehaviourScript : MonoBehaviour {
private Rigidbody rb;
// Use this for initialization
void Start () {
rb = GetComponent<Rigidbody>();
}
// Update is called once per frame
void FixedUpdate ()
{
float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertical = Input.GetAxis("Vertical");
Vector3 movement = new Vector3(moveHorizontal, 0,0f, moveVertical);
rb.AddForce(movement);
}
}
