Tween progress in iTween

Is there a way to check current tweening progress using iTween?
Also would be very useful to set up the event on some of the point… Is it possible also?

Depending on which function in iTween you are using you can set an OnUpdate Callback function in the Hashtable parameters. This function is called every update for the given tween movement and you can then manually calculate how far along it is. With this info you could then set up a system to do certain things at certain times, etc.
