Gameobject is null for no reason

Can you post some code? The only thing i can think of right now is that something else is destroying it on the 2nd frame

if you don't call the script in a proper way you will get null it have nothing to do with game object if it active in hirarchy or not so show us your code how do you call this script

So here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class CardLine : $$anonymous$$onoBehaviour
 {
 
     private SpriteRenderer myRenderer;
 
     void Awake ()
     {
         myRenderer = GetComponent<SpriteRenderer> ();
     }
 
     public void initialize ()
     {
         name = transform.parent.name + "_line";
         deactivate ();
     }
 
     public void activate (Color color)
     {
         myRenderer.enabled = true;
         myRenderer.color = color;
     }
 
     public void deactivate ()
     {
         if (this) {
             myRenderer = GetComponent<SpriteRenderer> ();
             if (myRenderer.enabled) {
                 myRenderer.color = Color.white;
                 myRenderer.enabled = false;
             }
         }
     }
 }
 

I use this script to outline cards in a card game. Before I activate the card I deactivate all of them --> deactivate() gets called. I know this works, as a debug in this method gets activated. But when I try to turn off the spriterenderer I get the message that it has been destroyed. So I added an if to check if it was there. But now I got an error that the object is destroyed. So I added an if to check if "this" is present but as I said its null on every seconds frame :(

Pls help :)

Cant add more comments.

So if i got this correctly you think that the script is trying to disable the spriterender of the object that calls deactivate(). I checked that.

So I think you are wrong here. I placed a Debug.Log(gameobject.name) in deactivate() and it debugs the correct name of the object that has the sprite renderer.
