Title: Automatically scroll to end of view
Post by: kruncher on October 20, 2013, 11:08:08 AM

I have a scroll panel with a vertical scrollbar which contains a simple label. The label is updated throughout game play.

How can I automatically scroll to the end as text is appended?

1. if (logLabel.text == "")
2.         logLabel.text = message;
3. else
4.         logLabel.text += "\n" + message;
5.  
6. // automatically scroll to end.
7. // Does not work :(
8. logScrollbar.value = 1f;
9.

UIDraggablePanel.SetDragAmount

This is almost working:

1. if (logLabel.text == "")
2.     logLabel.text = message;
3. else
4.     logLabel.text += "\n" + message;
5.  
6. // Automatically scroll to end.
7. logScroller.SetDragAmount(0, 1, false);
8.  

It scrolls to the entry before the latest.

1. Log("A");
2. Log("B");
3. Log("C");
4. Log("D"); // This one is at the bottom
5. Log("E"); // Need to manually scroll to see this fellow!
6.  

Any ideas?

Side Note: Passing "true" in to update the scrollbars causes the entire scroll panel to shift downwards (like when scroll scale is set to 0).

Calling "UpdateScrollbars" manually seems to resolve my issue though:

1. // Automatically scroll to end.
2. logScroller.UpdateScrollbars(true);    
3. logScroller.SetDragAmount(0, 1, false);
4.  

Thanks for pointing me in the direction of SetDragAmount!!
