Collision with object using MouseDrag

Questions & Answers
1

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 :smiley:
