When working on a project for mobile devices or PCs with touch input you will soon require basic gestures like tap, pan, pinch and zoom — they are not hard to implement manually using Unity API or using a package from Asset Store. The hard part is to make these gestures work together, e.g. to have a button with a tap gesture placed on a zoomable window. This is where you will need TouchScript — it makes handling complex gesture interactions on any touch surface an effortless job.
- TouchScript abstracts touch and gesture logic from input methods and platforms. Your touch-related code will be the same everywhere.
- TouchScript supports many touch input methods starting from smartphones to giant touch surfaces: mouse, Windows 7/8 touch, mobile (iOS, Android, Windows Store/Windows Phone), TUIO.
- TouchScript includes common gesture implementations: press, release, tap, long press, flick, pinch/scale/rotate.
- TouchScript allows you to write your own gestures and custom pointer input logic.
- TouchScript manages gestures in transform hierarchy and makes sure that the most relevant gesture will receive touch input.
- TouchScript comes with many examples and is extensively documented.
- TouchScript makes it easy to test multi-touch gestures without an actual multi-touch device using built-in second touch simulator (activated with Alt + click), TUIOPad on iOS or TUIODroid on Android. Read more.
- It's free and open-source. Licensed under MIT license.

To use TouchScript in your project you either need to
- download the latest release from Github,
- or get it from Asset Store,
- or clone the repository and use the source (more info on how to do it).
To test how TouchScript works, create an empty scene and drag two prefabs from TouchScript/Prefabs folder to the scene: TouchManager and Cursors. Press Play and click or touch (if your PC supports touch input) the Game View — you will see colored circles, pointer cursors.
Note: to simulate a second pointer you can hold Alt and click anywhere within the Game View.
You can make any GameObject react to touch input — just attach one of the scripts called Gestures to it. TouchScript ships with a few built-in Gestures which you can find in Component/TouchScript/Gestures menu. It is also possible to write your own gestures.
To test how built-in Gestures work, create an empty cube in the scene and attach a TransformGesture to it either from Component menu or Add Component button. Make the cube large enough to be able to touch it with two fingers. Attach another component called Transformer to the cube — this component listens to events from TransformGesture and applies translation, rotation and scaling to the GameObject.
Press Play. Note how you can drag the object with one touch and scale or rotate it with two touches. Don't forget that you can use Alt + click to simulate a second pointer (read more more about testing multi-touch gestures).
TouchScript comes with many examples in TouchScript/Examples folder. Open Examples.unity scene and read description for every example to find out what it is about.
