    I'm using a function calling a SpriteRenderer to show a small button notification above my character, implying that something will happen if you press said button.

    However, the way I implemented it (the same way Unity Docs does it, by declaring a Sprite list) means that I would have to refer to the sprites I want to display by index number in my list (called keyList) instead of filename.

    I would infinitely prefer to give my function a char instead of an index number for readability. I try to do this with
    Array.IndexOf(keyList, key)
    so I can get the index of the char-length file name, but using "Array" tells me that "Array" does not exist in this current context...

    So I try
    keyList.IndexOf(keyList, key)
    but THAT throws "Member cannot be accessed with an instance reference" and now I'm stuck.

    When I qualify the line with a type name, it says the type name doesn't exist, and when I use the variable name, it tells me to use the type name! :(

    This is (the important) parts of my code for refrence.

    Code (CSharp):
    1. private Sprite[] keyList;
    2. ...
    3.  
    4. ...
    5. void Start()
    6. {
    7.         keyList = Resources.LoadAll<Sprite>("Sprites/Player/Keys");
    8. }
    9. ...
    10.  
    11. ...
    12. public void ShowKey(bool show, char key){
    13.         if (show == false){
    14.             interactSpriteRenderer.sprite = null;
    15.         }
    16.         else if (show == true){
    17.            interactSpriteRenderer.sprite = keyList[keyList.IndexOf(keyList, key)]; //throws "instance refrence" error
    18.         }
    19.     }

    I think you were missing a
    using System;
    for the first issue you had. The
    Array
    class is in the System namespace.
