EventHandling for Unity 4.6 UI Event system

Hello All:

Unity 4.6 comes with new UI system which has different way of handling different event like mouse over, mouse out, mouse in, click etc.
In this post I will share how to handle these events properly in Unity 4.6 UI. Unity 4.6 UI provides following Interfaces to handle these events

• IPointerEnterHandler
• IPointerClickHandler
• IPointerExitHandler

Full List can be found here.

Following code shows how to handle these interfaces

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.EventSystems;

public class AwesomeGameObject : IPointerEnterHandler, IPointerClickHandler, IPointerExitHandler
{
    void Awake()
    {

    }

    public void Start()
    {
    }

    public void OnPointerEnter(PointerEventData eventData)
    {
        //handle this for pointer enter
    }

    public void OnPointerClick(PointerEventData eventData)
    {
        //Handle this for click
    }

    public void OnPointerExit(PointerEventData eventData)
    {
        //Handle this for exit
    }
}

Hope this helps. Happy coding.
