My character wont move

Ive been following the video for the “rollerball” game and everything has gone well until i come to test the game and the character doesnt respond to any input. I’ve tried different keys but nothing works. The script (that i copied from the video) is below. I’m not stuck as to why it doesnt respond as ive followed all directions.

using UnityEngine;
using System.Collections;

public class Playercontroller : MonoBehaviour 
{
	public float speed;

	void FixedUpdate ()
	{
				float moveHorizontal = Input.GetAxis ("Horizontal");
				float moveVertical = Input.GetAxis ("Vertical");

				Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);

				rigidbody.AddForce (movement * speed * Time.deltaTime);
		}
}

If your updating in the fixed update just dont use Time.deltaTime

Thats what can cause your movement very very slow. Check your inpur sertings Edit → project settongs → Input
