OnTriggerEnter2d not working

I am making a space game and need to detect when the player hits a collectable, i have tried using ontriggerenter2d but it is not working. Here is my code:

void OnTriggerEnter2D(Collider2D col)
{
if (col.gameObject.tag == "Coin")
{
coins = coins + 1;
}
}

 

Do you have a rigidBody2d attached to either your player or coin?

 

no, just 2d colliders

 

You need to attach a RigidBody2d to your coin and make sure kinetic isnt selected.

 

And make sure trigger on the coin is selected within the collider

 

ok, thanks i will try that

 

Thanks, that got it to work.

 

You're welcome

 

I have same isues .
When I add tag from inspector, problem is solved...
