Edit2 ^^ That is the code I have, for some reason the editor here is deleting parts of it.

So I’ve spent a significant amount of time on this issue and I’m wondering if it is a bug or if I’m just flippin nuts.

Okay so I have a 2D array of GameObject tiles with an x of 10 and y of 12. I have the array on a GameManager script on a separate GameObject in the scene.
When the game begins a circle is instantiated as a child of one of the gameObjects in the array, thus putting it on that ‘space’. The deal is I’m trying to access the GameManager script from the circle’s script through a public GameObject variable. This variable is set in the inspector so I should just be able to access the GameManager Script right?

The code I have to access the script is:

public GameManager gameManager;

TileInfo tileInfo = gameManager.tile[topLeftX, topLeftY].transform.GetComponent();

//This always gets a null reference exception.

I’m trying to access the 2D array from the gameManager.

Ultimately I’m looking to:
grab a script from the tile, through the gameManager’s 2Darray, through a public GameObject in the script that is above.

I’m sorry if this is confusing, I’ll put more if you think I need it, I’ve debugged down to that accessing the gameManager script is the problem.

Thanks!

Hello, @Mr0w3m.

Edit:
Maybe, the variable gameManager is null and not the array, since they’ve been instantiated. Unless, they were destroyed.

When calling, the GetComponent function, you need to set its parameter “type” to the type of the component you are trying to reference to. In this case, its TileInfo. Here is the documentation: Component.GetComponent.

TileInfo tileInfo = gameManager.tile[ topLeftX, topLeftY ].GetComponent< TileInfo >();
