Resolved Destroying GameObjects immediately is not permitted during physics trigger/contact, animation event

After collision of 2 game objects(collisionStay) I run this script:

Code (CSharp):

1. public void TakeDamage(int damage)
2.     {
3.         startHP -= damage;
4.         if(startHP <= 0)
5.         {
6.             float x = transform.position.x, y = transform.position.y, z = transform.position.z;
7.             var pos = walls.WorldToCell(transform.position);
8.             walls.SetTile(pos, null);
9.             GraphNode node = AstarPath.active.GetNearest(new Vector3(x, y + 1f, z)).node;
10.             node.Penalty = 1000;
11.             node = AstarPath.active.GetNearest(new Vector3(x, y + .5f, z)).node;
12.             node.Penalty = 1000;
13.             node = AstarPath.active.GetNearest(new Vector3(x - .5f, y + 1f, z)).node;
14.             node.Penalty = 1000;
15.             node = AstarPath.active.GetNearest(new Vector3(x - .5f, y + .5f, z)).node;
16.             node.Penalty = 1000;          
17.             gameObject.GetComponent<BoxCollider2D>().enabled = false;
18.             Destroy(gameObject,.1f);
19.         }
20.     }

And I get this error:

I don't know why. And I never had any issues destroying game objects before.
After googling for a while I've found DestroyImmidiate which I didn't even know existed before.
Also if those 2 gameobjects are staying in contact when am I'm supossed to destroy it?
I've tried setting the collider.enable to false and executing the destroy .1f later, but I'm still getting that error.

 

It seems to be an issue with the TileMap method. The SetTile method is calling an internal "ClearTile" That is using the "DestroyImmediate" method.

 

Thanks that helped me. And I've fixed it. It seems like you can't just setTile to null on collide.
For future generations here is the fix:
First I've made the collider disabled and set the sprite to null so it appears as if it was destroyed. I've deleted the line Destroy(gameObject). Then I've started a coroutine to delay the setTile(null) which deleted the gameobject as well since it was attached on the rule tile.

 

Hello @ChuanXin, any updates on the progress of this? I am facing a similar issue.
