Question by alexjolig · Jul 24, 2016 at 08:41 AM · unity5drag-and-drop

How do I detect OnDrop event on a GameObject?

I need to implement drag & drop system in my project which I did using this code.

using UnityEngine; using System.Collections;

 public class DragDrop : MonoBehaviour {
 
     private Vector3 offset;
 
     void OnMouseDown()
     {
 
         offset = gameObject.transform.position -
             Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, 4f));
     }
 
     void OnMouseDrag()
     {
         Vector3 newPosition = new Vector3(Input.mousePosition.x, Input.mousePosition.y, 4f);
         transform.position = Camera.main.ScreenToWorldPoint(newPosition) + offset;
     }
   }

Now I need to implement OnDrop event like the one we use in canvas.

 public class Slot : MonoBehaviour, IDropHandler
 {
     public void OnDrop(PointerEventData eventData)
     {
         Debug.Log("Somthing Dropped!");
     }
 }

As far as I know I can't use IDragHandler events out of canvas, so Is there anyway to detect OnDrop event on a GameObject like the above code?
