[URGENT HELP]GameObject is already being activated or deactivated

The console keeps showing this error for days and it comes to the script:

Code (CSharp):

1. void OnCollisionExit2D(Collision2D collision)
2.     {
3.         if (collision.gameObject.tag == "MovingPlatform")
4.         {      
5.              gameObject.transform.parent = null;
6.         }
7.     }

I am making a tag system mechanic that involves deactivating and activating 2 character gameobject in unity. reply asap

 

Knowing more information would be useful. Otherwise https://answers.unity.com/questions/1381007/gameobject-is-already-being-activated-or-deactivat.html and https://forum.unity.com/threads/gameobject-is-already-being-activated-or-deactivated.279888/ might be helpful. Its always worth checking other forums.

 

Im still having issues: the messages still appear and now my characters drop through the ground and shows GetShape == null?? What is this??! Help please anyone im going insane

Code (CSharp):

1.  void OnCollisionEnter2D(Collision2D collision)
2.     {
3.         if (collision.gameObject.tag == "MovingPlatform")
4.         {
5.             gameObject.transform.parent = collision.transform;
6.             Collider2D[] colliders2 = GetComponentsInChildren<Collider2D>();
7.             foreach (var collider in colliders2)
8.             {
9.                 collider.enabled = true;
10.             }
11.         }
12.         if (collision.gameObject.tag == "Ground")
13.         {
14.             Collider2D[] colliders = GetComponentsInChildren<Collider2D>();
15.             foreach (var collider in colliders)
16.             {
17.                 collider.enabled = true;
18.             }
19.         }
20.     }
21.     //CollisionExit for player exiting MovingPlatform.
22.     void OnCollisionExit2D(Collision2D collision)
23.     {
24.         if (collision.gameObject.tag == "MovingPlatform")
25.         {      
26.              gameObject.transform.parent = null;
27.             Collider2D[] colliders2 = GetComponentsInChildren<Collider2D>();
28.             foreach (var collider in colliders2)
29.             {
30.                 collider.enabled = false;
31.             }
32.         }
33.         if (collision.gameObject.tag == "Ground")
34.         {
35.             Collider2D[] colliders = GetComponentsInChildren<Collider2D>();
36.             foreach (var collider in colliders)
37.             {
38.                 collider.enabled = true;
39.             }
40.         }
41.     }
42.  
43.  
44. void OnEnable()
45.     {
46.         Collider2D[] colliders = GetComponentsInChildren<Collider2D>();
47.         foreach (var collider in colliders)
48.         {
49.             collider.enabled = true;
50.         }
51.         //transform.SetParent(null);
52.     }

 

Im not completely sure what your end goal is. But if you look at your code, you are setting your colliders enabled to false after leaving a moving platform. If you do this, the gameobject will no longer detect collisions and will pass through everything and won't trigger any onCollider checks. Which is probably why you are going through the ground? That would be my guess anyway.

I also apologise for the long reply time...

 

You also want to look at your code and break it down more. You are basically repeating the same piece of code 5 times. If you split it off into a function that just takes a true or false parameter and then sets the collider to that value, it'll be more efficient, take up less space, look cleaner and it'll be easier to debug.
