Unity 3D Touchable/Clickable Hyperlinked Objects with 'guiText' Components

OpenWebLink.cs

/*
 * For use with Unity 4.5
 */
using UnityEngine;
using System.Collections;

public class OpenWebLink : MonoBehaviour {

    public string url;

    // Use this for initialization
    void Start () {

    }
	
    // Update is called once per frame
    void Update () {
        if (IsClicked() || IsTouched()) {
            Application.OpenURL(url);
        }
    }

    bool IsTouched() {
        bool touched = false;
        if (Input.touchCount == 1) {
            Touch touch = Input.touches[0];
            if (touch.tapCount == 1 && touch.phase == TouchPhase.Ended) {
                if (guiText.HitTest(touch.position)) {
                    touched = true;
                }

                clicked = true;
            }
        }   
        return clicked;
    }

}

OpenWebLink46.cs

/*
 * For use with Unity 4.6
 */
using UnityEngine;
using UnityEngine.EventSystems;
using System.Collections;

public class OpenWebLink : MonoBehaviour, IPointerClickHandler {
	
	public string url;

	public void Start() {
		if (string.IsNullOrEmpty(url)) {
			Debug.LogWarning("No URL has been set in the OpenWebLink component, disabling component");
			enabled = false;
		}
	}

	public void OnPointerClick(PointerEventData eventData) {
		OpenURL();
	}

	public void OpenURL() {
		Application.OpenURL(url);
	}

	public void OpenURL(string aUrl) {
		Application.OpenURL(aUrl);
	}		
}

The updated class for Unity 4.6 is smaller and also works on any of the new GUI components.
