Protected Methods

Method Description
ApplyOffset ( BetterList verts, int start ) : Vector2

Align the vertices, making the label positioned correctly based on the pivot. Returns the offset that was applied.
OnAnchor ( ) : void

If the label is anchored it should not auto-resize.
OnDisable ( ) : void

Remove the font texture change listener.
OnInit ( ) : void

Register the font texture change listener.
OnStart ( ) : void

Determine start-up values.
OnValidate ( ) : void

Validate the properties.
SetActiveFont ( Font fnt ) : void

Set the active font, correctly setting and clearing callbacks.
UpgradeFrom265 ( ) : void

Upgrading labels is a bit different.

Private Methods

Method Description
GetCharacterIndex ( Vector2 localPos ) : int
GetCharacterIndex ( Vector3 worldPos ) : int
OnFontTextureChanged ( ) : void

Notification called when the Unity's font's texture gets rebuilt. Unity's font has a nice tendency to simply discard other characters when the texture's dimensions change. By requesting them inside the notification callback, we immediately force them back in. Originally I was subscribing each label to the font individually, but as it turned out mono's delegate system causes an insane amount of memory allocations when += or -= to a delegate. So... queue yet another work-around.
