On Trigger Enter 2D

Physics & collisionsDetailedOnTriggerEnter2D

A 2D collider enters this 2D trigger.

A 2D physics event: it happens when a 2D collider (Box Collider 2D and the like) enters this object's 2D area (a Collider 2D with Is Trigger on). It isn't for regular 3D colliders or players.

One of the two colliders needs a Rigidbody 2D. Both the area and the collider that came in get the event. For 3D areas, see On Trigger Enter (Collider).
