How to identify with gameObject from a list of gameObjects was clicked

Hello,

I have an array of randomly generated ball prefabs.

I can check that I am clicking on any ball 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:

Code (CSharp):

1. private void OnMouseDown()
2.     {
3.         print("clicked");
4.     }

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

 

Since you've already got a script attached to each ball, I suggest you create a variable in that script for storing some kind of unique identifier (e.g. ID number) and set that variable right after you Instantiate the ball.

 

thank you so much! this worked nicely
