OnTriggerExit2D, OnTriggerEnter2D is not working


I just spend hours on internet to find why functions are not working but I didn’t find answer. Functions looks like that:
void OnTriggerEnter2D (Collider2D col) {
Debug.Log (" It is Working!!“);
if (col.gameObject.tag == “ScoreChecker”) {
Debug.Log (” It is Working!!");

void OnTriggerExit2D (Collider2D col) {
	Debug.Log (" It is Working!!");
	if (col.gameObject.tag == "ScoreChecker") {

And screenshots of Ball and Trigger:

You should add the BoxCollider2D component on a ball also.

Make sure you put the script on a gameobject that has a 2d collider on it with is Trigger not checked.alt text
