Hi I’m new to using Unity and tried doing collision the original code below is what I tired
So then I tried to just put the col.isTrigger by itself in the if statement it doesn’t show anything in the console log
Help would be greatly appreciated.

public class jabTrigger : MonoBehaviour {
    public int jabDamage = 10;

    void onTriggerEnter2D(Collider2D col)
    {
        if (col.isTrigger != true && col.CompareTag("Enemy"))
        {
            col.SendMessageUpwards("underAttack", jabDamage);
            Debug.Log("collision");
        }
    }

Enemy script

    void Update () {
          if (currHealth <= 0)
         {
                Destroy(gameObject);
         }
   }
    public void underAttack(int damage)
    {
        currHealth -= damage;
        Debug.Log(currHealth);
       
    }

}
