I've heard about tweening but I have never heard about Tweening like this. I've looked into tweening and such, but I really have no idea where to start on this one. This can be seen as the first text box in this game: here goes out. Does anyone know how they did this?
If you look at the properties of a Frame scroll to the bottom and you see one that says "ClipsDescendants" if that is true then whatever UI that is inside that from will only be shown within the frame. So if it goes out of it, such as tweening, it will be cut off.
