It might feel strange to talk about "Scripting without scripting," but there are a few systems that help you generate scripts without having to actually write code yourself.
iTween (https://www.assetstore.unity3d.com/#/content/84) is a free animation system to create smooth transitions between positions and other transformations, giving a pleasing, professional feel to animations.
A companion system to iTween is the Visual Editor for iTween, which replaces writing code with a visual programming interface, available at: https://www.assetstore.unity3d.com/#/content/180
Another visual programming system, which is even more extensive, is uScript, available at https://www.assetstore.unity3d.com/#/content/1808. It is actually a commercial system that is still in beta at the time of writing, but there is a watermarked free Personal Learning Edition .
