IDragHandler not called

Hi guys,

I wanted to try out Unity Event System, so I did the following:

1. Added EventSystem in scene by click GameObject > UI > Event System
2. Added a Physics Raycaster onto the Main Camera by clicking Component > Event > Physics Raycaster
3. Added the following script onto the Main Camera:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.Events;
4. using UnityEngine.EventSystems;
5.  
6. public class MovementController : MonoBehaviour, IDragHandler {
7.  
8.     #region IDragHandler implementation
9.     void IDragHandler.OnDrag (PointerEventData eventData)
10.     {
11.         Debug.Log ("Drag Detected!");
12.         throw new System.NotImplementedException ();
13.     }
14.     #endregion
15.  
16.     // Use this for initialization
17.     void Start () {
18.    
19.     }
20.    
21.     // Update is called once per frame
22.     void Update () {
23.    
24.     }
25. }

But it doesn't seem to detect any of my drag when I play. I'm not sure what I missed.

Looking forward to your help!

 

What you are trying to achieve?Drag on a ui element?
If so ,then you have to create a ui -> button, image etc and then add your script to that.

you could call only

Code (CSharp):

1. void OnDrag (PointerEventData eventData)
2.     {
3.         Debug.Log ("Drag Detected!");
4.         throw new System.NotImplementedException ();
5.     }

 

The problem is that you are putting this onto Main Camera, this script needs to be on an object with a collider on it.
