How to auto scroll a scrollview when text gets bigger?

Example (C#):

Code (csharp):

1.  
2. Vector2 scrollPosition;
3. int lines=0;
4.    
5. // The string to display inside the scrollview. 2 buttons below add  clear this string.
6. String longString = "This is a long-ish string";
7.  
8.     public void OnGUI () {
9.  
10. scrollPosition = GUILayout.BeginScrollView (
11. scrollPosition, GUILayout.Width (100), GUILayout.Height (100));
12.  
13. GUILayout.Label (longString);
14.  
15.  
16. GUILayout.EndScrollView ();
17.  
18.  
19. if (lines<=15){
20.     longString += "\nHere is another line";
21.         lines++;
22.  
23.     }
24. }

 

Tigeba on IRC post this code, and it works! We have to create a GUISkin.

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class Cliente : MonoBehaviour
6. {
7.         public GUISkin  mySkin;
8.     Vector2 scrollPosition;
9.     int lines=0;
10.  
11.     // The string to display inside the scrollview. 2 buttons below add  clear this string.
12.     string longString = "This is a long-ish string";
13.  
14.     public void OnGUI()
15.     {
16.         GUI.skin = mySkin;
17.  
18.         GUIStyle bt = mySkin.GetStyle( "SmallText" );   // Get custom style from skin
19.         scrollPosition = GUILayout.BeginScrollView( scrollPosition, GUILayout.Width( 200 ), GUILayout.Height( 100 ) );
20.  
21.         GUILayout.Label( longString, bt );
22.  
23.         GUILayout.EndScrollView();
24.  
25.  
26.  
27.        
28.  
29.         if( lines<=25 )
30.         {
31.             longString += "\nHere is another line";
32.             lines++;
33.  
34.  
35.  
36.             GUIContent gc = new GUIContent( longString );
37.             scrollPosition.y = bt.CalcHeight( gc, 100 ) - 100;  // Width is 100, and height is 100, so scroll any extra space.
38.         }
39.        
40.         if (GUILayout.Button ("Add More Text"))
41.         {
42.             longString += "\nHere is another line";
43.             GUIContent gc = new GUIContent( longString );
44.             scrollPosition.y = bt.CalcHeight( gc, 100 ) - 100;  // Width is 100, and height is 100, so scroll any extra space.
45.         }
46.     }
47. }
