Input.GetTouch

Description

Returns object representing status of a specific touch. (Does not allocate temporary variables).

	// Moves object according to finger movement on the screen
	var speed : float = 0.1;
	function Update () {
		if (Input.touchCount > 0 && 
		  Input.GetTouch(0).phase == TouchPhase.Moved) {
		
			// Get movement of the finger since last frame
			var touchDeltaPosition:Vector2 = Input.GetTouch(0).deltaPosition;
			
			// Move object across XY plane
			transform.Translate (-touchDeltaPosition.x * speed, 
						-touchDeltaPosition.y * speed, 0);
		}
	}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float speed = 0.1F;
    void Update() {
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
            Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
            transform.Translate(-touchDeltaPosition.x * speed, -touchDeltaPosition.y * speed, 0);
        }
    }
}

	public speed as float = 0.1F

	def Update() as void:
		if (Input.touchCount > 0) and (Input.GetTouch(0).phase == TouchPhase.Moved):
			touchDeltaPosition as Vector2 = Input.GetTouch(0).deltaPosition
			transform.Translate(((-touchDeltaPosition.x) * speed), ((-touchDeltaPosition.y) * speed), 0)

Another example:

	// Instantiates a projectile whenever the user taps on the screen
	var projectile : GameObject;
	function Update () {
		for (var i = 0; i < Input.touchCount; ++i) {
			if (Input.GetTouch(i).phase == TouchPhase.Began) {
				clone = Instantiate (projectile, transform.position, transform.rotation);
			}
		}
