Question Use a list to define what objects i should ignore the collision

I have a GameObject list which holds the objects that i can ignore the collision with, but I'm struggling to get the object's Collider2D element.

Here it is my foreach loop that runs in a circle overlap list and (at least try) to get the object's collider2D:

Code (CSharp):

1.  
2. List<GameObject> collisors = new List<GameObject>();
3.  
4.  
5. foreach(var colObj in circleOverLap){
6.     if(collisors.Contains(colObj)){
7.         Collider2D col = colObj.GetComponent<Collider2D>();  
8.         Physics2D.IgnoreCollision(col, GetComponent<Collider2D>());
9.     }
10. }

The error return is this
error CS1503: Argument 1: cannot convert from 'UnityEngine.Collider2D' to 'UnityEngine.GameObject'

 

Why are you using

List<GameObject>

instead of

List<Collider2D>

?

 

Because if I use a list of colliders, I can't put the prefabs in them

 

1. You can absolutely put prefabs in a List<Collider2D>
2. Why do you want/need to put prefabs in the list? That doesn't make sense. Putting prefabs in this list won't ever work the way you want it to.
