How to identify which prefab clicked out of array of cloned prefabs

[imposter_syndrom_incarnated]

Hello,

I have an array of randomly generated ball prefabs.

I can check that I am clicking on any ball prefab because the ball prefab, called N-back in the picture above (with many clones as you can see) , has a script attached with this method:

private void OnMouseDown()
    {
        print("clicked");
    }

Yet I want to be able to identify which specific ball I am clicking because eventually I want the user to click them in order trying to remember the order in which the balls were instantiated on the screen, because I instantiate them one by one in random order.
I don’t know how to identify which ball/gameObject/clone of the list created is being clicked by my mouse.
I tried to print the name of each, they all have the same name. The positions are obviously different but I don’t know how this information would be useful to distinguish the balls on click.
Any suggestion would be much appreciated

It’s up to you. Do you want the names to be different? Then assign the names you want to each Prefab instance right after you instantiate it. Do you want to work with a number instead of a name? Then create a public int myNumber on your script (perhaps the same script that has OnMouseDown), and assign a number to that public variable for each Prefab, right after you instantiate the Prefab. Basically, you create the data you need yourself, and then read it later.
