Tween) The newly created tween instance
Creates a new tween that animates the target_object variables from the specified values (from the current values) and returns its index.
You define the starting values and the current values are used as the destination values which is great for doing things like animating objects onto the screen because you can set them up initially the way you want them to look at the end of the tween and then animate in from elsewhere.
