Create destroyed prefab

I tried that, but I am getting an error:

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?)

Here is my script:

 using UnityEngine;
 using System.Collections;
 
 public class aim : $$anonymous$$onoBehaviour {
     
     public static int cheat = 0;
     
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if (cheat==1)
             //Destroy(this.gameObject);
             gameObject.SetActive(false);
         
         
     float h = Input.GetAxis ("Horizontal") * Time.deltaTime * moveSpeed;
         float v = Input.GetAxis ("Vertical") * Time.deltaTime * moveSpeed;
         transform.Translate (h,v,0);
         
             
     }
 }

Are you using Unity version 3.x or 4.x? SetActive was introduced in 4.0. If you're using a version previous to 40, do the following:

 gameObject.active = false;

If you're using Unity 4 and you're getting this error then write back, because Game Objects most certainly do have this method: see here.

You're very likely calling this from the Update loop and shouldn't. Update isn't running on disabled objects. $$anonymous$$ove it to a method and call it another way.

 GameObject objectToSetInactive;
 
 void Cheat()
 {
     objectToSetInactive.active = !objectToSetInactive.active;
 }

Well, part of why I didn't is because your code doesn't show how you set cheat to 1. If it's from an external script, then just make Cheat() public and call it ins$$anonymous$$d of setting an int to 1. That's the way you should have done it from the beginning, because checking a flag every frame is pointless when you can just call a method.

Of course, SetActive is just a regular old public method. In order to call it you just have to get a reference to the game object. The question of how to do it is, for some reason, asked almost everyday on unity answers, so a quick search should give you loads of examples.

Edit: I forgot you're using 3.x. In your case, the active variable is also public, so just replace any SetActive examples with that. :)
