iTween Visual Editor
Many of you will have read the post I wrote about the awesome iTween class for Unity (by Bob Berkebile aka pixelplacement) back in March of this year. Now another user has stepped up and made this already fantastic resource a visual editor that you can simply drop onto objects. Massive props go to David Koontz, who has developed and is offering this as a free download, take a look at his blog post and find the download here -

and remember you’ll also need to grab the actual iTween class itself from Bob’s site, go grab it here -

The main page that is kept up to date is actually located here: http://dkoontz.wordpress.com/itween-visual-editor/
Also, iTween is included with the visual editor since version 0.5, just grab it off the asset store and you’re good to go.
