Collision with object using MouseDrag

Question

Hey, I'm trying to use OnMouseDrag() to detect colision with the object I drag, like Fruit Ninja, but it don't detect colision

I used using UnityEngine; using System.Collections;

 public class MouseDrag : MonoBehaviour {
 
     void OnMouseDrag() 
     {
         print ("worked");
         Destroy(this.gameObject);
     }
 }

It dont print and don't destroy the gameobject, I need to use some colision enter or something like that ? I want to detect collision only when I'm dragging

You need add collider componant to your gameobj to detect collision. this is code i make with unity2d

    void OnMouseDown()
    {
          screenPoint = Camera.main.WorldToScreenPoint(gameObject.transform.position);
     
      offset = gameObject.transform.position - Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, screenPoint.z));
     
 }
 
 void OnMouseDrag()
 {
         Vector3 curScreenPoint = new Vector3 (Input.mousePosition.x, Input.mousePosition.y, screenPoint.z);    
         Vector3 curPosition = Camera.main.ScreenToWorldPoint (curScreenPoint) + offset;
         transform.position = curPosition;
 }

and detect collision

void OnCollisionEnter2D(Collision2D collision) { if (collision.gameObject.tag == "your_gameobj_for_collision") {
Destroy(gameObject); } }

and sure set trigger of collider componant = false :D
