problem with scripts-amazing racer

Hi all. First of all I want to mention that I am new in unity.
I am going through the book Unity Game Development by Mike Geig and I’m stuck.
In chapter called ‘‘First Game Amazing Racer’’ when I copy new scripts to my Asstes there is an errors saying: Assets/scripts/GameControlScript.cs(18,16): error CS0246: The type or namespace nameCharacterMotor' could not be found. Are you missing a using directive or an assembly reference? and Assets/scripts/GameControlScript.cs(19,16): error CS0246: The type or namespace name MouseLook’ could not be found. Are you missing a using directive or an assembly reference?
Can somone please tell me how to fix it so I can continue learning?
Many thanks

You’re missing the MouseLook script, when it’s referenced by Type in the GameControlScript.cs script and fails to find it it throws an error.

You can find this script in the standard assets asset on the unity store, not knowing what version you’re using i will assume 5.x+, link below:

Standard Assets for unity 5.x

Thank you for quick answer. I have dowloaded everything but still saying the same problem I copied MouseLook script where I have the other srcipts but then asked me to copy first person script, after that asked me to copy rigibody etc.
When I did everything it asked me the problem remains the same.
Just thinking maybe there is a problem witha script GameControl itself?
Unfortunately I do not know anything about scripting:/
It looks like that:

using Unity.Engine;
using System.Collections;

public class GameControlScript : MonoBehaviour {

//The amount of ellapsed time
private float time = 0;

//Flags that control the state of the game
private bool isRunning = false;
private bool isFinished = false;

//place holders for the player and the spawn point
public Transform spawnPoint;
public GameObject player;

//place holders for the scripts on the character controller
public CharacterMotor motorScript;
public MouseLook lookScript;

//This resets to game back to the way it started
private void InitLevel()
	time = 0;
	isRunning = true;
	isFinished = false;
	//move the player to the spawn point
	player.transform.position = spawnPoint.position;
	//Allow the character controller to move and
	//look around
	motorScript.enabled = true;
	lookScript.enabled = true;

// Use this for initialization
void Start () {
	//prevent the character controller
	//from looking around
	motorScript.enabled = false;
	lookScript.enabled = false;

// Update is called once per frame
void Update () {
	//add time to the clock if the game
	//is running
		time += Time.deltaTime;

//This runs when the player enters the finish
public void FinishedGame()
	isRunning = false;
	isFinished = true;
	//freeze the character controller
	motorScript.enabled = false;
	lookScript.enabled = false;

//This section creates the Graphical User Interface (GUI)
void OnGUI()
		string message;
			message = "Click to Play Again";
			message = "Click to Play";
		if(GUI.Button(new Rect(Screen.width / 2 - 70, Screen.height/2, 140, 30), message))
			//start the game if the user clicks to play
			InitLevel ();
	//If the player finished the game, show the final time
		GUI.Box(new Rect(Screen.width / 2 - 65, 185, 130, 40), "Your Time Was");
		GUI.Label(new Rect(Screen.width / 2 - 10, 200, 20, 30), ((int)time).ToString());
	//If the game is running, show the current time
	else if(isRunning)
		GUI.Box(new Rect(Screen.width / 2 - 65, Screen.height - 115, 130, 40), "Your Time Is");
		GUI.Label(new Rect(Screen.width / 2 - 10, Screen.height - 100, 20, 30), ((int)time).ToString());


Can please somone help?
