OnTriggerEnter2D not working

Question

So what i'm trying to do is make my Player (which has a Circle Collider 2D and a Rigidbody 2D) hit a coin (circle colider 2D + is trigger activated) and make the coin disappear.

But my player and coin are simply not doing anything, the player just goes over the coin.

I have verified the layer, sorting layer, order in layer, the coin tag and they're all ok. I also checked in the physics 2D in the Project Settings and the Coin layer and the Player layer are selected to collide. When i get the 'is trigger' off the coin, they do collide but that's not what i want, i need it to be a trigger.

The script i'm using on the player is:

 void OnTriggerEnter2d(Collider2D collider)
     {
         if (gameObject.tag == "Coin")
         {
             Destroy(coin);
             gm.Points += 1;
         }
     }

(Ignore the gm.Points += 1, that's a part of my score system, and i doubt it's part of the problem.)

What should i do about it?

OnTriggerEnter2D, not OnTriggerEnter2d...

Well I think your main problem is that you're checking the tag of the current gameObject and not the object you're triggering. Your condition if (gameObject.tag == "Coin") is checking if the object that actually contains this script has the tag "Coin".

I suppose the object that holds this script in your game is your Player object (maybe with the "Player" tag), so when you ask if (gameObject.tag == "Coin"), it just won't run. I think what you really want is to use if (collider.tag == "Coin") instead of if (gameObject.tag == "Coin").

Also check the spelling of your event. It should be OnTriggerEnter2D

Let me know if doing this simple change you get what you expected :)
