error cs1061

ThirdPersonController doesn’t work

Assets/Standard Assets/Utility/EventSystemChecker.cs(18,55): error CS1061: Type ‘UnityEngine.EventSystems.StandaloneInputModule’ does not contain a definition for ‘forceModuleActive’ and no extension method ‘forceModuleActive’ of type ‘UnityEngine.EventSystems.StandaloneInputModule’ could be found (are you missing a using directive or an assembly reference?)

using System;
using System.Collections;
using UnityEngine;
using UnityEngine.EventSystems;

public class EventSystemChecker : MonoBehaviour
    //public GameObject eventSystem;

	// Use this for initialization
	void Awake ()
            GameObject obj = new GameObject("EventSystem");
            obj.AddComponent<StandaloneInputModule>().forceModuleActive = true;

the error is here forceModuleActive = true;

This tutorial is misleading, as its example script does not compile in Unity. How could this example be fixed?
