Buenas!!
Os comparto un script en C# para hacer un joystick (también se adapta a TouchPad). El script es un port de Javascript a C# del joystick que trae Unity3D en Standart Asset. Os dejo el código y por si no sabéis como configurarlo os comparto también un vídeo explicación:

// PORT DE Joystick.js A Joystick.cs
//Nicolás Sánchez Baile
// Joystick creates a movable joystick (via GUITexture) that
// handles touch input, taps, and phases. Dead zones can control
// where the joystick input gets picked up and can be normalized.
//
// Optionally, you can enable the touchPad property from the editor
// to treat this Joystick as a TouchPad. A TouchPad allows the finger
// to touch down at any point and it tracks the movement relatively
// without moving the graphic
//////////////////////////////////////////////////////////////
