During the development for the "Molecules" project we have made over 100 different scripts for Unity. We have also spent a lot of time on the user interactions. We built different type of cursors (like a 2d or 3d cursor type), different kind of menu-systems and behavior like "tap&hold" or even a "tripple-touch-double-click" (say that five times quickly)... First we was thinking about making a commercial product - something like a MultiTouch, drag and drop, out of the box solution.
But to be honest: we can not afford that. Making a serious "product" with that compexity would exceed by far our capacities. Than we was thinking about releasing something like a "uniTUIO GOLD" edition where you would have access to all those scripts and stuff we have developed for a small yearly fee. Unfortunately we have right now so much to do and so many projects to roll, that we simply do not have the time for doing that (cleaning up code can be very time consuming).
So what's up now? To be honest – we don't know exactly what will happen with "GOLD". Maybe we will release some parts of it as a collection of commercial scripts and assets. Who knows - just visit this site often and listen to the news ;-) Anyhow: Just have a look at the scripts and the prefabs we have developed. You will see some of them on this page, but you can head over in the projects section for some more "Molecules" info.
Background Info: A Prefab is a type of asset inside Unity3d -- a reusable GameObject stored in Project View. Prefabs can be inserted into any number of scenes, multiple times per scene. When you add a Prefab to a scene, you create an instance of it. All Prefab instances are linked to the original Prefab and are essentially clones of it. No matter how many instances exist in your project, when you make any changes to the Prefab you will see the change applied to all instances. A lot of the used MutiTouch objects are allready made as a prefab (like some buttons, menus or mouse-cursors). For using them in your MultiTouch applications, you can simply drag and drop them on your scene.
You can see also a short video of Ben, demonstrating some "Tap&Hold" capabilities. Have fun!
