how to distinguish two "Box Collider 2D" in the script?

Hi,everybody!


In the Inspector, I have two "Box Collider 2D", each has a script to process different function. But how to distinguish two "Box Collider 2D" in the script?
Below is the sample:

void OnTriggerEnter2D(Collider2D other) -------------how to distinguish "other"?
{
........
}

 

Now I've learned using like this:
"Collider2D[] cols = GetComponents<Collider2D>();"
But I want to use the first one, "cols[0]" is wrong. Could anybody tell me how to use the first one?

 

If the positions or the size stays the same you could check that

 

your meaning is using "foreach(Collider2D one in cols))", then judge every one on its own property?
like this?

foreach (var t in GetComponentsInChildren<Transform>())
{
if (!originalStructure.Contains(t))
{
t.parent = null;
}
}

But is there a another way to use the first one, like "cols[0]" ? thanks
