Author: Andre Odendaal

Description

Uses the first detected touch to rotate the camera. The sensitivity can be set as well as the axis inverted.

C# - TouchLook.cs

using UnityEngine;

public class TouchLook : MonoBehaviour {
 
    public float sensitivityX = 5.0f;
    public float sensitivityY = 5.0f;
 
    public bool invertX = false;
    public bool invertY = false;
 
	// Use this for initialization
	void Start () {
 
	}
 
	// Update is called once per frame
	void Update () {
        if (Input.touches.Length > 0)
        {
            if (Input.touches[0].phase == TouchPhase.Moved)

                Vector2 delta = Input.touches[0].deltaPosition;
                float rotationZ = delta.x * sensitivityX * Time.deltaTime;
