Finding out which Panel was clicked in function

Question

I have a panel with 10 sub panels in it. I am using Event Trigger to intercept the messages from these sub panels OnPointerDown event calls some function in the some script of an Game Object.

Is there a way to know in the function which of the sub panels was clicked. That way I can use the same function for all the sub panels or should I make individual function for each of the sub panels.

Answer 1

PointerEventData.pointerPress returns The `GameObject` that received the OnPointerDown. 

So you can do something like this :

OnPointerDown(PointerEventData e)
{
  Debug.Log(e.pointerPress.name);
}

Edit to answer the question in the comments. You can make the function you are calling in the event trigger require a BaseEventData argument. Then you can cast that argument to a PointerEventData like in the following example :

public void test1(BaseEventData data)
    {
        PointerEventData e = data as PointerEventData;
        Debug.Log(e.pointerPress.name);
    }

Answer 2

The easiest way I see is, To attach a small script on each one, when clicked it will call a function and pass as parameter an index indicating which sub panel was clicked.

There is probably a better/more optimized way to go about it if you have many panels, but in the range of 0-10 I think it can work well.
