Make URL as clickable in Lable string

[swaraj]

Hi all,

How can we achieve this? I've a string with urls lets say "something http://www.google.com again http://www.amazon.com" or "http://www.google.com nexturl http://www.amazon.com". Now what I want is, when I am showing this string (in a UILabel), I could make the link clickable, i.e., the link should act like a url, so that when I click it, it should open me the respective link.

This topic relates the same I wanted to achieve : http://www.tasharen.com/forum/index.php?topic=7809.0, but it does not provide any solutions

Please provide me some suggestions on how to achieve this.

Thanks in advance.

There is no such functionality in NGUI. Not yet. It's on the list of things to add.

You can currently hack it just by using label.GetCharacterIndex(UICamera.lastHit.point) to determine the index of the character under the mouse, then see if you're over your link by doing some text parsing.

Here's the full script:

1. using UnityEngine;
2.  
3. [RequireComponent(typeof(UILabel))]
4. public class ClickableLink : MonoBehaviour
5. {
6.         void OnClick ()
7.         {
8.                 UILabel lbl = GetComponent<UILabel>();
9.  
10.                 int index = lbl.GetCharacterIndex(UICamera.lastHit.point);
11.                
12.                 if (index != -1)
13.                 {
14.                         string text = lbl.text;
15.  
16.                         int linkStart = text.LastIndexOf(' ', index, index) + 1;
17.                         int linkEnd = text.IndexOf(' ', index);
18.                         if (linkEnd == -1) linkEnd = text.Length;
19.                         if (linkStart == linkEnd) return;
20.  
21.                         string url = text.Substring(linkStart, linkEnd - linkStart);
22.                         if (url.StartsWith("http://")) Application.OpenURL(url);
23.                 }
24.         }
25. }
