    As the title says, what's the most efficient way to covert List<Raycasthit2D> to List<Collider2D> where the collider2D are the corresponding colliders of the Raycasthit2D

    Code (CSharp):
    1. var colliderList = raycastList.Select(rhit=>rhit.collider).ToList();

    You'll also need to use linq namespace to use method which iSinner posted: using System.Linq on top of your script. You can also do it with more "traditional" method, by loop(it doesnt need linq):

    Code (CSharp):
    1. List<Collider2D> collidersList = new List<Collider2D>();
    2. for(int i = 0; i < raycastHitList.Count; i ++){
    3.     collidersList.Add(raycastHitList[i].collider);
    4. }

    Thanks for the replies guys, I ended up using

    Code (CSharp):
    1. List(T).ConvertAll(TOutput)
