[Tweener] Tweener Digest, Vol 17, Issue 20

[Jonathan Marston]

Right, this is a text typer. I used it to make a little  
"Loading . . . . ." message. I wanted the message to start with  
"Loading" and then append the dots. The existing _text tween would  
start by removing the old text "Loading" each character one at a time,  
and then building it up one character at a time to be the final text  
"Loading . . . . . ". The included shortcut appends new text to  
anything that exists already.

a cool enhancement would be to automagically figure out the shortest  
path between the old text and the new text, and just tween the  
differences. Possibly by stepping through the characters one at a time  
or using regexp to do something more clever/elegant.
