Question Confusion about making lists equal to each other.

Hi, I am new to unity and am trying to make a game. I was wondering how you make two lists have the same elements but not refer to the same place in memory, and how you check whether there values are equal. I know that just saying listOne = listTwo just makes them refer to the same place in memory but am a bit confused about comparing the lists and .Equals. Thank you in advance.

 

If you want to create a new list, you must create a new list. List has a constructor which takes any IEnumerable (including another List) and makes a shallow copy:

Code (CSharp):

1. List<Whatever> list2 = new List<Whatever>(list1);

 

As Praetor hints above, broadly there's the notion of a deep and shallow copy, and also this notion:

Value Types vs Reference Types:

So if you're making a list of a value types, each entry in the list is a distinct instance, whereas with a list of reference types, that might not be the case, depending if you duped the individual target items.
