Remove a prefab from list

I have a list of enemies. I am instantiating this enemy from list.
After the enemy is destroy i wana remove this enemy from list.
How do i do this
On destroy function i am using enemylist.remove(this.gameobject);

But it doesnt since spawned enemy is an instance of prefab from list.

So how do i do this

Thanks

 

You should add the prefabs name to instances name or to the name of an its child. You just check the name when you need to remove prefab
Ex:

Code (CSharp):

1.  
2.         GameObject enemyInstance = Instantiate(enemylist[index]);
3.         enemyInstance.transform.Find("preb_name").name = enemylist[index].name;

...and remove

Code (CSharp):

1.         foreach(GameObject obj in enemylist)
2.         {
3.             if(obj.name == this.transform.Find("preb_name").name)
4.             {
5.                 enemylist.Remove(obj);
6.                 break;
7.             }
8.         }

 

If you are instantiating from a list and you don't need to use that enemy prefab again, just remove it after you instantiate a clone. Or if you are creating several copies, just remove it when you create your last copy.

 

I need to remove enemy from list only after enemy is dead

 

Then you need to record something about the index they are in. Either have a variable for the name, a variable for the Gameobject, or if you can only have one enemy from the list out at a time, then just use the index. @BiDuc gives you an example that would be similar to a string variable by naming the newly created object instead.
