OnTriggerEnter2D - is there any other way to specify triggered object?

So far I was using tags to specify with which object there will be interaction, but I wonder if I can use for example SerializeField for that?

The way I'm doing it so far:

Code (CSharp):

1.     void OnTriggerEnter2D(Collider2D collision)
2.     {
3.         if (collision.CompareTag("Trigger"))
4.         {
5.             trigger = collision.gameObject.GetComponent<TriggerScript>();
6.             trigger.switcher = 1;
7.             Destroy(gameObject);
8.         }
9.     }

Is there any way to use something like SerializeField:

Code (CSharp):

1. [SerializeField]
2.     private GameObject Trigger;

?

 

You could, but then you'd only care about interactions with a single gameobject:

Code (csharp):

1.  
2.     void OnTriggerEnter2D(Collider2D collider)
3.     {
4.         if (collider.gameObject == Trigger)
5.         {
6.  

Which might be what you want?

You could also just check if the component you care about is there:

Code (csharp):

1.  
2.     void OnTriggerEnter2D(Collider2D collider)
3.     {
4.         if (collider.TryGetComponent<TriggerScript>(out var trigger)) {
5.             trigger.swticher = 1;
6.             Destroy(gameObject);
7.         }
8.     }
9.  

 

This is exactly what I needed. Thank you!

I wanted to avoid adding sooo much tags to my game.
