Storing GameObject In Multitype Array Object

I am trying to build a 2d array of multiple data types

[Int],[Int],[Int],[GameObject]

So I used this
static Object[,] LetterTiles = new Object[64,4];

Then I can store the game object like this
LetterTiles[1,3] = new GameObject("MyLetterTile");

I cant find a way to set properties directly from the array, without first copying the GameObject out of the Array to a new Variable.

These Don't work:
(GameObject) LetterTiles[1,4].AddComponent<SpriteRenderer>();
LetterTiles[1,4](GameObject).AddComponent<SpriteRenderer>();
LetterTiles[1,4].AddComponent<SpriteRenderer>();


This does but I am hoping there is a better way.
GameObject currentWorkingLetter;
currentWorkingLetter = LetterTiles[1,4];
currentWorkingLetter.AddComponent<SpriteRenderer>();
LetterTiles[1,4] = currentWorkingLetter

When I copy currentWorkingLetter = LetterTiles[1,4]

Does that create a duplicate Game Object in the Scene?;
Is there a better way to do this?

 

No that does not create a duplicate object in the scene, but it does create a seperate variables so any changes wont effect the GameObject in the array. You should be able to do the following line to quickly access and change the GameObject in the Array without a new variable:

Code (csharp):

1. ((GameObject)LetterTile[1,4]).AddComponent<SpriteRenderer>();

This is different than what you have because you are converting it to a GameObject after trying to add the SpriteRenderer. Putting it in the parenthesis allows the typecast to happen before you call AddComponent.

 

Thank you !

Also, Afterward I found out that you can not store type [int] in type [object]
