Collision2D on gameObject tag doesn't work SOLVED!

1. Basically, my hero will do some stuffs like slashing the melon, but the collision doesn't work. It just passed through the melon (image below):


2. I configured the components needed.
Tag = watermelonTag
Is Trigger = checked


3. I place this code in my Hero game object.

Code (CSharp):

1. void OnCollisionEnter2D (Collision2D collision){
2.      
3.         switch (collision.gameObject.tag){
4.  
5.         case "watermelonTag":
6.             srSlash.sprite = slashingSprite;
7.             audio.PlayOneShot(swordSound);
8.             audio.PlayOneShot(fruitSmashing);
9.             Destroy(collider.gameObject);
10.             break;
11.         case "pineappleTag":
12.             srSlash.sprite = slashingSprite;
13.             audio.PlayOneShot(swordSound);
14.             audio.PlayOneShot(fruitSmashing);
15.             Destroy(collider.gameObject);
16.             break;

Thanks )

 

Wouldnt it be "OnTriggerEnter2D" ...since u set it to "Is Trigger"?
