Easy C# question

Sorry for the noob question, but I am following a very easy tutorial about C# and getting a error, even copying the code and the same steps from the tutorial:

using UnityEngine;
using System.Collections;

public class ActiveObjects : MonoBehaviour
    void Start ()

And the error:

Assets/Scripts/ActiveObjects.cs(8,20): error CS1061: Type UnityEngine.GameObject' does not contain a definition for SetActive’ and no extension method SetActive' of type UnityEngine.GameObject’ could be found (are you missing a using directive or an assembly reference?)

Seems very simple to me and I don’t know why isn’t working.

Thanks :wink:

Wow thank you guys!! I am using 3.4 version and with the OrangeLightning code it’s working fine… Now I’ll be more careful and check the Unity’s versions in tutorials! Greets :wink:
