onTriggerExit error

basically i have a script to stream terrains is verry simple

Code (CSharp):

1.  void OnTriggerEnter(Collider col)
2.     {
3.         if (col.tag == "Loader")
4.         {
5.             this.gameObject.transform.GetChild(0).gameObject.SetActive(true);
6.         }
7.     }
8.     void OnTriggerExit(Collider col)
9.     {
10.         if (col.tag == "Loader")
11.         {
12.             this.gameObject.transform.GetChild(0).gameObject.SetActive(false);
13.         }
14.     }

it worked normally but yesterday a random error just pop up:
Destroying GameObjects immediately is not permitted during physics trigger/contact, animation event callbacks or OnValidate. You must use Destroy instead.
UnityEngine.GameObject:SetActive(Boolean)
Streamer:OnTriggerExit(Collider) (at Assets/Scripts/Streamer.cs:18)

the line 18 is :

Code (CSharp):

1. this.gameObject.transform.GetChild(0).gameObject.SetActive(false);

can someone tell me why is this happening ?

 

Perhaps you have a DestroyImmediate call inside an OnDisable event in a script attached to some child? Just guessing...

 

not really just the terrain from unity with no scripts attached no more gameobjects just the terrain.

 

I am having the same problem. All I am doing is hiding Terrains, AI and objects that are faraway based on player's postion.

Code (CSharp):

1.  private void OnTriggerEnter(Collider other)
2.     {
3.         if ((DetectLayer & 1 << other.gameObject.layer) == 1 << other.gameObject.layer)
4.         {
5.             foreach (Transform sec in SectionsHide)
6.             {
7.                 sec.gameObject.SetActive(false);
8.             }
9.  
10.             foreach (Transform sec in SectionsUnHide)
11.             {
12.                 sec.gameObject.SetActive(true);
13.             }
14.         }
15.     }

I keep getting this error:

Destroying GameObjects immediately is not permitted during physics trigger/contact, animation event callbacks or OnValidate. You must use Destroy instead.
UnityEngine.GameObject:SetActive(Boolean)
