A collection of useful functions that can be called directly on lists.

RandomEntry

List<int> myList = [1, 2, 3, 4];
Debug.Log(myList.RandomEntry());
// Will return either 1, 2, 3, or 4

RandomIndex

List<int> myList = [1, 2, 3, 4];
Debug.Log(myList.RandomIndex());
// Will return either 0, 1, 2, or 3

Debug.Log(myList.RandomIndex(1));
// Will return either 0, 2, or 3

ExtractComponent

List<GameObject> candyObjects = new List<GameObject>(GameObject.FindGameObjectsWithTag("Candy"));
