Title: Box-Collider does not adjust when changing label text programatically
Post by: 10FingerArmy on February 16, 2014, 05:00:09 AM

I do have a UILabel with a box collider and activated auto-adjust in it's widget. This works fine in the editor. If I change the text at runtime though the collider does not change automatically. I have to call

text.GetComponent<UILabel>().text = "New Text";
text.GetComponent<UIWidget>().ResizeCollider();

to make it work which is unfortunate. Is there a way to have it resize automatically?

NGUI 3.4.9

Same issue in v3.6.2, but only happens if changes the UILabel.text while it's inactive.

I still have the same issu in v3.7.4. Any workaround?

Edit: tried using an invisible widget as the gameobject for the collider, and anchoring it to the label. The widget resizes correctly but the collider still doesn't.

Edit2: I wrote a little piece of script that calls a resize on the collider if it finds a difference, during Update(). Just attach it to the label that has a collider, works as-is.

Quote from: UpdateLabelCollider.cs

1. using UnityEngine;
2. using System.Collections;
3.  
4. [RequireComponent(typeof(Collider), typeof(UILabel))]
5. public class UpdateLabelCollider : MonoBehaviour
6. {
7.         private Collider _col;
8.         private UILabel _lab;
9.  
10.         void OnEnable()
11.         {
12.                 _col= gameObject.GetComponent<Collider>();
13.                 _lab= gameObject.GetComponent<UILabel>();
14.         }
15.        
16.         void Update ()
17.         {
18.                 if(_lab.width != _col.bounds.size.x || _lab.height != _col.bounds.size.y)
19.                         _lab.ResizeCollider();
20.         }
21. }

It all works fine with 3.7.6.
