[Unity] 4.6 Beta Error

I am currently getting a error in this script but I can't seem to understand it, I've done the same in another script the drag handlers etc; and it works great.

Anyway here is the script.

Code (CSharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using UnityEngine.UI;
5. using UnityEngine.EventSystems;
6.  
7. public class CraftSlot : MonoBehaviour, IDragHandler, IPointerExitHandler, IPointerEnterHandler, IPointerDownHandler{
8.  
9.     CraftingSystem craftSystem;
10.     Inventory inventory;
11.     public int slotIndex;
12.     Image image;
13.     // Use this for initialization
14.     void Start () {
15.         image = gameObject.transform.GetChild(0).GetComponent<Image>();
16.         craftSystem = GameObject.FindGameObjectWithTag("CraftSystem").GetComponent<CraftingSystem>();
17.         inventory = GameObject.FindGameObjectWithTag("Inventory").GetComponent<Inventory>();
18.         image.enabled = false;
19.     }
20.    
21.     // Update is called once per frame
22.  
23.     //shows icon
24.     void Update () {
25.  
26.         if (craftSystem.itemsinCraftSystem[slotIndex].itemName != null)
27.         {
28.             image.sprite = craftSystem.itemsinCraftSystem[slotIndex].itemIcon;
29.             image.enabled = true;
30.         }
31.     }
32.  
33.  
34.     //dragging item in slot
35.     public void OnPointerDown(PointerEventData data)
36.     {
37.        
38.         //dragging the item into the slot in aswell
39.         if (inventory.draggingItem)
40.         {
41.             craftSystem.itemsinCraftSystem[slotIndex] = inventory.draggedItem;
42.             inventory.closeDraggedItem();
43.         }
44.     }
45.  
46.     public void OnPointerEnter(PointerEventData data)
47.     {
48.         if (inventory.Items[slotIndex].itemName != null && !inventory.draggingItem)
49.         {
50.             inventory.showTooltip(inventory.Slots[slotIndex].GetComponent<RectTransform>().localPosition, inventory.Items[slotIndex]);
51.         }
52.     }
53. }
54.  

The error I am getting.

Assets/Scripts/CraftSlot.cs(6,14): error CS0535: `CraftSlot' does not implement interface member
`UnityEngine.EventSystems.IDragHandler.OnDrag(UnityEngine.EventSystems.PointerEventData)'

Assets/Scripts/CraftSlot.cs(6,14): error CS0535: `CraftSlot' does not implement interface member `UnityEngine.EventSystems.IPointerExitHandler.OnPointerExit(UnityEngine.EventSystems.PointerEventData)'

 

You are missing OnDrag and OnPointerExit. If you don't need them then remove them from interface list

 

Thanks man. I assumed it was a bug.

 

Not really a bug, I had the same issue. Just don't implement the interfaces if you aren't going to use them.
