How to rotate an Object with touch input and stop it slowly after that in Unity?

I got some code from here:
https://answers.unity.com/questions/34317/rotate-object-with-mouse-cursor-that-slows-down-on.html
private float rotationSpeed = 10.0F;
private float lerpSpeed = 1.0F;
private Vector3 theSpeed;
private Vector3 avgSpeed;
private bool isDragging = false;
private Vector3 targetSpeedX;
void OnMouseDown() {
isDragging = true;
}
void Update() {
if (Input.GetMouseButton(0) && isDragging) {
theSpeed = new Vector3(-Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"), 0.0F);
avgSpeed = Vector3.Lerp(avgSpeed, theSpeed, Time.deltaTime * 5);
} else {
if (isDragging) {
theSpeed = avgSpeed;
isDragging = false;
}
float i = Time.deltaTime * lerpSpeed;
theSpeed = Vector3.Lerp(theSpeed, Vector3.zero, i);
}
transform.Rotate(Camera.main.transform.up * theSpeed.x * rotationSpeed, Space.World);
transform.Rotate(Camera.main.transform.right * theSpeed.y * rotationSpeed, Space.World);
}
This code rotates an object with mouse click and drag and after this click, the object stops slowly. I want this function now on mobile. This is my code for the mobile version:
// Update is called once per frame
public void Update() {
// Track a single touch as a direction control.
if (Input.touchCount > 0) {
Touch touch = Input.GetTouch(0);
// Handle finger movements based on touch phase.
switch (touch.phase) {
// Record initial touch position.
case TouchPhase.Began:
startPos = touch.position;
directionChosen = false;
break;
// Determine direction by comparing the current touch position with the initial one.
case TouchPhase.Moved:
direction = touch.position - startPos;
break;
// Report that a direction has been chosen when the finger is lifted.
case TouchPhase.Ended:
directionChosen = true;
stopSlowly = true;
Debug.Log("end");
break;
}
}
if (directionChosen) {
// Something that uses the chosen direction...
theSpeed = new Vector3(-direction.x, direction.y, 0.0F);
avgSpeed = Vector3.Lerp(avgSpeed, theSpeed, Time.deltaTime * 5);
} else {
if (stopSlowly) {
Debug.Log("TESTOUTPUT");
theSpeed = avgSpeed;
isDragging = false;
}
float i = Time.deltaTime * lerpSpeed;
theSpeed = Vector3.Lerp(theSpeed, Vector3.zero, i);
}
transform.Rotate(camera.transform.up * theSpeed.x * rotationSpeed, Space.World);
transform.Rotate(camera.transform.right * theSpeed.y * rotationSpeed, Space.World);
And here are some variables, I use Vector2 variables for startPos and direction:
private float rotationSpeed = 1f;
private float lerpSpeed = 1.0F;
private Vector3 theSpeed;
private Vector3 avgSpeed;
private bool isDragging = false;
private Vector3 targetSpeedX;
public Vector2 startPos;
public Vector2 direction;
public bool directionChosen;
public bool stopSlowly;
Now if I press play and rotate the Object on my phone, it rotates but it does not end on its own. It also rotates very fast. When I touched the Object one time, it stops immediately.
Please can someone say me what exactly is wrong with my code. My goal is just a rotation, initialized from touch input and an slow end until its stand still.
Thanks

I use some physics now to solve this problem:
// React on User Touch Input -> Rotate gameObject
if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
// Get movement of the finger since last frame
Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
// Add Torque to gameObject
rb.AddTorque(camera.transform.up * -touchDeltaPosition.x/* * optionalForce*/);
rb.AddTorque(camera.transform.right * touchDeltaPosition.y/* * optionalForce*/);
} else if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended) {
// throw anker, stop rotating slowly
rb.angularDrag = 0.7f;
}
This code is for touch Input and rotates an object + stops it down slowly. You need an Rigidbody on your object which you want to rotate. Here its called rb. camera is my main Camera.

your condition is very confusing.
try something like this
// Handle finger movements based on touch phase.
switch (touch.phase) {
// Record initial touch position.
case TouchPhase.Began:
startPos = touch.position;
break;
// Determine direction by comparing the current touch position with the initial one.
case TouchPhase.Moved:
direction = touch.position - startPos;
isDragging = true;
break;
// Report that a direction has been chosen when the finger is lifted.
case TouchPhase.Ended:
isDragging = false;
stopSlowly = true;
Debug.Log("end");
break;
}
if (isDragging) {
// Something that uses the chosen direction...
theSpeed = new Vector3(-direction.x, direction.y, 0.0F);
avgSpeed = Vector3.Lerp(avgSpeed, theSpeed, Time.deltaTime * 5);
} else {
if(stopSlowly) {
Debug.Log("TESTOUTPUT");
theSpeed = avgSpeed;
stopSlowly = false;
}
float i = Time.deltaTime * lerpSpeed;
theSpeed = Vector3.Lerp(theSpeed, Vector3.zero, i);
}

Rotate 2D Sprite with Virtual Joystick

I am trying to rotate a GameObject along z-axis using Joystick, but its rotating y-axis. I might missed some math calculation. Any Help??
Reference Image
void FixedUpdate()
{
// get input from joystick
// get input from joystick
rightJoystickInput = rightJoystick.GetInputDirection();
float xMovementRightJoystick = rightJoystickInput.x; // The horizontal movement from joystick 02
float zMovementRightJoystick = rightJoystickInput.y; // The vertical movement from joystick 02
// if there is only input from the right joystick
if (rightJoystickInput != Vector3.zero)
{
// calculate the player's direction based on angle
float tempAngle = Mathf.Atan2(zMovementRightJoystick, xMovementRightJoystick);
xMovementRightJoystick *= Mathf.Abs(Mathf.Cos(tempAngle));
zMovementRightJoystick *= Mathf.Abs(Mathf.Sin(tempAngle));
// rotate the player to face the direction of input
Vector3 temp = transform.position;
temp.x += xMovementRightJoystick;
temp.z += zMovementRightJoystick;
Vector3 lookDirection = temp - transform.position;
if (lookDirection != Vector3.zero)
{
rotationTarget.localRotation = Quaternion.Slerp(rotationTarget.localRotation, Quaternion.LookRotation(lookDirection) * Quaternion.Euler(0, 45f, 0), rotationSpeed * Time.deltaTime);
}
}
}

You don't need most of the code in your question and this is really simple.
1.Find the angle with Mathf.Atan2 then multiple it with Mathf.Rad2Deg.
2.Use Quaternion.Euler(new Vector3(0, 0, angle)) to get the rotation then apply it to the Object.
This should be one in the Update function not FixedUpdate because FixedUpdate is used to move Rigidbody Objects.
public Transform rotationTarget;
public bool flipRot = true;
void Update()
{
rightJoystickInput = rightJoystick.GetInputDirection();
float horizontal = rightJoystickInput.x;
float vertical = rightJoystickInput.y;
float angle = Mathf.Atan2(horizontal, vertical) * Mathf.Rad2Deg;
angle = flipRot ? -angle : angle;
rotationTarget.rotation = Quaternion.Euler(new Vector3(0, 0, angle));
}
If using Rigidbody2D then use Rigidbody2D.MoveRotation in the FixedUpdate function. The rest of the code stays the-same.
public Rigidbody2D rg2d;
public bool flipRot = true;
void FixedUpdate()
{
rightJoystickInput = rightJoystick.GetInputDirection();
float horizontal = rightJoystickInput.x;
float vertical = rightJoystickInput.y;
float angle = Mathf.Atan2(horizontal, vertical) * Mathf.Rad2Deg;
angle = flipRot ? -angle : angle;
rg2d.MoveRotation(angle);
}
EDIT:
But only the problem is when i leave joystick its rotation is setting
to 0 instantly which looks too odd. How can i fix it?
You have to detect when you release the joystick in OnPointerUp then slowly lerp the joystick thump back to the Zero position. You also have to lerp the current target object angle to zero or to its default value and this should be done in a coroutine function. When OnPointerDown is called, stop the current coroutine function. Prevent the code in FixedUpdate from running when finger is released so that it won't interfere with the coroutine function.
For the sake of completeness, below is the combination of a Joystick code and the Rigidbody answer above:
public class VirtualJoystickController : MonoBehaviour,
IDragHandler, IPointerUpHandler, IPointerDownHandler

private Image joystickImg;
public float mas_distance = 7f;
void Start()
{
bgImg = GameObject.Find("JoystickBGImage").GetComponent<Image>(); // the joysticks background
joystickImg = GameObject.Find("Joystickthumb").GetComponent<Image>(); // the joystick object to use
}
private Vector3 _inputDirection = Vector3.zero;
//the movementDirection
public Vector3 joystickInputDirection
{
set
{
//Change only if value is different from old one
if (_inputDirection != value)
{
_inputDirection = value;
Debug.Log("Dir: " + _inputDirection);
}
}
get
{
return _inputDirection;
}
}
public void OnDrag(PointerEventData eventData)
{
dragJoyStick(eventData);
}
void dragJoyStick(PointerEventData eventData)
{
Vector3 tempDir = Vector3.zero;
Vector2 pos = Vector2.zero;
if (RectTransformUtility.ScreenPointToLocalPointInRectangle
(bgImg.rectTransform,
eventData.position,
eventData.pressEventCamera,
out pos))
{
pos.x = (pos.x / bgImg.rectTransform.sizeDelta.x);
pos.y = (pos.y / bgImg.rectTransform.sizeDelta.y);
float x = (bgImg.rectTransform.pivot.x == 1) ? pos.x * 2 + 1 : pos.x * 2 - 1;
float y = (bgImg.rectTransform.pivot.y == 1) ? pos.y * 2 + 1 : pos.y * 2 - 1;
tempDir = new Vector3(x, y, 0);
if (tempDir.magnitude > 1)
{
tempDir = tempDir.normalized;
}
joystickImg.rectTransform.anchoredPosition = new Vector3(
tempDir.x * (bgImg.rectTransform.sizeDelta.x / mas_distance),
tempDir.y * (bgImg.rectTransform.sizeDelta.y / mas_distance));
joystickInputDirection = tempDir;
}
}
public void OnPointerDown(PointerEventData eventData)
{
released = false;
//Stop current coroutine
if (retCoroutine != null)
StopCoroutine(retCoroutine);
if (eventData.pointerCurrentRaycast.gameObject == bgImg.gameObject ||
eventData.pointerCurrentRaycast.gameObject == joystickImg.gameObject)
{

}
}
public void OnPointerUp(PointerEventData eventData)

float counter = 0;
//Get the current position of the object to be moved
Vector2 currentThumb = thumbstickTransform.anchoredPosition;
while (counter < duration)
{
counter += Time.deltaTime;
//Slowly returns thumbstick
Vector2 tempThumbStickVal = Vector2.Lerp(currentThumb, toPosition, counter / duration);
joystickInputDirection = tempThumbStickVal;
thumbstickTransform.anchoredPosition = tempThumbStickVal;
//Slowly returns the target Object to original pos
float tempTargetObjAngle = Mathf.Lerp(angle, originalAngle, counter / duration);
rg2d.MoveRotation(tempTargetObjAngle);
yield return null;
}
}
public float returnTime = 1.0f;
public Rigidbody2D rg2d;
public bool flipRot = true;
const float originalAngle = 0;
bool released = true;
float angle;
Coroutine retCoroutine;
void FixedUpdate()
{
if (released)
return;
float horizontal = joystickInputDirection.x;
float vertical = joystickInputDirection.y;
angle = Mathf.Atan2(horizontal, vertical) * Mathf.Rad2Deg;
angle = flipRot ? -angle : angle;
rg2d.MoveRotation(angle);
}
}

your function calculates a point where you want to look at:
Vector3 temp = transform.position;
temp.x += xMovementRightJoystick;
temp.z += zMovementRightJoystick;
Vector3 lookDirection = temp - transform.position;
this point is on the XZ plane, that is why the car rotates on Y axis
if you want to rotate on Z axis, calculate a point on XY plane like this:
Vector3 temp = transform.position;
temp.x += xMovementRightJoystick;
temp.y += zMovementRightJoystick;
Vector3 lookDirection = temp - transform.position;
PS: i don't know why you multiply with Quaternion.Euler(0, 45f, 0) - that is a constant angle on Y axis, it just means that each lookDirection will be rotated for 45 degrees - i would have to see your scene to know why you need this...

Player Movement using joystick based on camera facing

I am developing an offline FPS multiplayer game.
When the Player Rotation value is (0,0,0), then Player moves perfectly in direction. However, my problem is when I rotate the camera using touch input. The player can also rotate his face and press the joystick button for moving the player, but then the player should not move the direction the camera is facing.

Your camera and joystick code looks fine, but that's not where the problem is.
I'll assume your player movement code looks something like this:
Get input X and Y
Move player right by X, forward by Y
In code form, that might look something like this:
//returns the world-space direction that player wants to move
Vector3 GetDesiredMovement(float inputForward, float inputRight) {
//get a vector pointing to player's right
Vector3 dirRight = Camera.main.transform.right;
dirRight.y = 0f;
dirRight.Normalize();
//get a vector pointing to player's front
Vector3 dirForward = Camera.main.transform.forward;
dirForward.y = 0f;
dirForward.Normalize();
//calculate desired movement based on input
Vector3 desiredMovement = (dirForward * inputForward) + (dirRight * inputRight);
desiredMovement.Normalize();
return desiredMovement;
}
What if "right" and "forward" need to be relative to some other object in the scene, such as a camera? It's easier than you might think: just read those values directly from the camera's transform component.
You could do that by replacing just two lines from the above example:
Vector3 dirRight = Camera.main.transform.right;
Vector3 dirForward = Camera.main.transform.forward;

I solved the problem of basing player movement of the camera's direction.
In my Player's script there are two lines that read joystick input:
movement.velocity.x = joystick.GetComponent<VirtualJoystick> ().Horizontal () * 5f;
movement.velocity.z = joystick.GetComponent<VirtualJoystick> ().Vertical () * 5f;`
I changed them to this:
Vector3 DirectionVector =
new Vector3 (joystick.GetComponent<VirtualJoystick> ().Horizontal (), 0f, joystick.GetComponent<VirtualJoystick> ().Vertical ());
movement.velocity = transform.rotation * DirectionVector * 10f;
Directly add joystick value in movement vector. I just multiply it to the joystick input vector and solve my problem.
Now the player moves based on the player rotation and where the camera is facing.
Thanks everyone for help.

Pinch-To-Zoom with Unity 5 UI

I'm trying to re-implement a pinch-to-zoom system in a Unity UI-based app. About six months ago I was able to hack one together by making the UI canvas a child of a regular GameObject, and manipulating that object's transform, but since updating to Unity 5.5+ I find this doesn't work. The closest I can get allows the pinch gesture to change the canvas' scaleFactor, which a) can make images, panels, etc resize improperly depending on their alignments, and b) won't allow me to pan once zoomed.
What I have so far is this:
public class PinchToZoomScaler : MonoBehaviour {
public Canvas canvas; // The canvas
public float zoomSpeed = 0.5f; // The rate of change of the canvas scale factor
public float _resetDuration = 3.0f;
float _durationTimer = 0.0f;
float _startScale = 0.0f;
void Start() {
_startScale = canvas.scaleFactor;
}
void Update()
{
// If there are two touches on the device...
if (Input.touchCount == 2) {
// Store both touches.
Touch touchZero = Input.GetTouch (0);
Touch touchOne = Input.GetTouch (1);
// Find the position in the previous frame of each touch.
Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition;
Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition;
// Find the magnitude of the vector (the distance) between the touches in each frame.
float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude;
float touchDeltaMag = (touchZero.position - touchOne.position).magnitude;
// Find the difference in the distances between each frame.
float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag;
// ... change the canvas size based on the change in distance between the touches.
canvas.scaleFactor -= deltaMagnitudeDiff * zoomSpeed;
// Make sure the canvas size never drops below 0.1
canvas.scaleFactor = Mathf.Max (canvas.scaleFactor, _startScale);
canvas.scaleFactor = Mathf.Min (canvas.scaleFactor, _startScale * 3.0f);
_durationTimer = 0.0f;
} else {
_durationTimer += Time.deltaTime;
if (_durationTimer >= _resetDuration) {
canvas.scaleFactor = _startScale;
}
}
}
}
As I said, this works to a degree, but doesn't give me a nice uniform zooming, not does it allow me to pan the canvas. Thanks in advance for any help.

if (_temp > distance)

return;

else if (_temp < distance)

Reminder: This script only works in canvas objects

You can use this function ( just pass to it negative deltaMagnitudeDiff )
Also it is good to multiplay deltaMagnitudeDiff with a ratio like ( 0.05 )
float currentScale = 1f;
void Zoom (float increment)
{
currentScale += increment;
if (currentScale >= maxScale)
{
currentScale = maxScale;
}
else if (currentScale <= minScale)
{
currentScale = minScale;
}
rectTransform.localScale = new Vector3 (currentScale, currentScale, 1);
pan.ValidatePosition ();
}
For Panning,
you can use something like this :
public class Pan : MonoBehaviour
{
public float Speed;
Vector3 startDragPosition;
public void BeginDrag ()
{
startDragPosition = Input.mousePosition;
}
public void Drag ()
{
transform.localPosition += (Input.mousePosition - startDragPosition) * Speed;
startDragPosition = Input.mousePosition;
ValidatePosition ();
}
public void ValidatePosition ()
{
var temp = transform.localPosition;
var width = ((RectTransform)transform).sizeDelta.x;
var height = ((RectTransform)transform).sizeDelta.y;
var MaxX = 0.5f * width * Mathf.Max (0, transform.localScale.x - 1);
var MaxY = 0.5f * height * Mathf.Max (0, transform.localScale.y - 1);
var offsetX = transform.localScale.x * width * (((RectTransform)transform).pivot.x - 0.5f);
var offsetY = transform.localScale.y * width * (((RectTransform)transform).pivot.y - 0.5f);
if (temp.x < -MaxX + offsetX)
temp.x = -MaxX + offsetX;
else if (temp.x > MaxX + offsetX)
temp.x = MaxX + offsetX;
if (temp.y < -MaxY + offsetY)
temp.y = -MaxY + offsetY;
else if (temp.y > MaxY + offsetY)
temp.y = MaxY + offsetY;
transform.localPosition = temp;
}
Just call the functions ( BeginDrag & Drag ) from the Events Trigger component.

what i did to scale an object using pinch was this, it works on any touch screen when the object is in the middle of the screen:
if (Input.touchCount == 2)
{
//The distance between the 2 touches is checked and subsequently used to scale the
//object by moving the 2 fingers further, or closer form eachother.
Touch touch0 = Input.GetTouch(0);
Touch touch1 = Input.GetTouch(1);
if (isScaling)//this will only be done if scaling is true
{
float currentTouchDistance = getTouchDistance();
float deltaTouchDistance = currentTouchDistance - touchDistanceOrigin;
float scalePercentage = (deltaTouchDistance / 1200f) + 1f;
Vector3 scaleTemp = transform.localScale;
scaleTemp.x = scalePercentage * originalScale.x;
scaleTemp.y = scalePercentage * originalScale.y;
scaleTemp.z = scalePercentage * originalScale.z;
//to make the object snap to 100% a check is being done to see if the object scale is close to 100%,
//if it is the scale will be put back to 100% so it snaps to the normal scale.
//this is a quality of life feature, so its easy to get the original size of the object.
if (scaleTemp.x * 100 < 102 && scaleTemp.x * 100 > 98)
{
scaleTemp.x = 1;
scaleTemp.y = 1;
scaleTemp.z = 1;
}
//here we apply the calculation done above to actually make the object bigger/smaller.
transform.localScale = scaleTemp;
}
else
{
//if 2 fingers are touching the screen but isScaling is not true we are going to see if
//the middle of the screen is looking at the object and if it is set isScalinf to true;
Ray ray;
RaycastHit hitTouch;
ray = cam.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));
if (Physics.Raycast(ray, out hitTouch, 100f))
{
if (hitTouch.transform == transform)
{
isScaling = true;
//make sure that the distance between the fingers on initial contact is used as the original distance
touchDistanceOrigin = getTouchDistance();
originalScale = transform.localScale;
}
}
}
}

Unity C# use Transform.RotateAround with touch to move camera around target

So am looking at changing my Transform.RotateAround script for touch input. If I get rid of the "Input.GetAxis", the camera rotates on its own around the target. I cant seem to figure out how to format the code to get the position of the touch to a string to use with this. If anyone has any tips that would be awesome!
Here is the code:
using UnityEngine;
using System.Collections;
[AddComponentMenu("Camera-Control/Mouse Orbit with zoom2")]
public class MouseOrbitImproved2 : MonoBehaviour {
public float speed;
public Transform target;
public float rotateSpeed;
public Transform camera = Camera.main.transform;
public Vector3 camPosition;
public float camSpeed;
public float minDistance;
public float maxDistance;
//private Vector3 moveDirection = Vector3.zero;
//private Vector3 moveDirection = target.position;
public float perspectiveZoomSpeed = 0.5f; // The rate of change of the field of view in perspective mode.
public float orthoZoomSpeed = 0.5f; // The rate of change of the orthographic size in orthographic mode.
void start() {
//camPosition = camera.transform.position;
}
public void Update() {
if (Input.touchCount == 1) {
transform.LookAt(target);
Touch touchSwipe = Input.GetTouch(0);
string position = touchSwipe.deltaPosition;
transform.RotateAround(target.position, Vector3.up, Input.GetAxis(position)* speed);
transform.RotateAround(target.position, Vector3.forward, Input.GetAxis(position)* speed);
}
transform.LookAt(target);
/*
float scroll = Input.GetAxis("Mouse ScrollWheel");
if (scroll != 0)
{
// calculate new position first...
camPosition += transform.forward * scroll * camSpeed;
// then compare to the limits:
float distanceToTarget = Vector3.Distance(target.position, camPosition);
// you can clamp the movement to min and max distances:
if (distanceToTarget > maxDistance){ // clamp at maxDistance...
camPosition = target.position - maxDistance * transform.forward;
}
if (distanceToTarget < minDistance){ // or at minDistance
camPosition = target.position - minDistance * transform.forward;
}
// finally, update the actual camera position:
transform.position = camPosition;
// set camera position
}
*/
// If there are two touches on the device...
if (Input.touchCount == 2)
{
// Store both touches.
Touch touchZero = Input.GetTouch(0);
Touch touchOne = Input.GetTouch(1);
// Find the position in the previous frame of each touch.
Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition;
Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition;
// Find the magnitude of the vector (the distance) between the touches in each frame.
float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude;
float touchDeltaMag = (touchZero.position - touchOne.position).magnitude;
// Find the difference in the distances between each frame.
float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag;
// If the camera is orthographic...
if (Camera.main.orthographic)
{
// ... change the orthographic size based on the change in distance between the touches.
Camera.main.orthographicSize += deltaMagnitudeDiff * orthoZoomSpeed;
// Make sure the orthographic size never drops below zero.
Camera.main.orthographicSize = Mathf.Max(Camera.main.orthographicSize, 0.1f);
}
else
{
// Otherwise change the field of view based on the change in distance between the touches.
Camera.main.fieldOfView += deltaMagnitudeDiff * perspectiveZoomSpeed;
// Clamp the field of view to make sure it's between 0 and 180.
Camera.main.fieldOfView = Mathf.Clamp(Camera.main.fieldOfView, 0.1f, 179.9f);
}
}
}
public void ChangeToAxial (){
Camera.main.transform.position = new Vector3 (45.3f,234.5f,66.9f);
}
public void ChangeToSagright (){
Camera.main.transform.position = new Vector3 (28.13f,76.41f,222.68f);
}
public void ChangeToSagleft (){
Camera.main.transform.position = new Vector3 (49.36f,66.85f,-93.78f);
}
public void ChangeToCoronal () {
Camera.main.transform.position = new Vector3 (-71.6f,69.66f,66.29f);
}
}

I think it may be best if you look at this question and answer from the unity forum Unit 5 forum rotating camera with touch. It should work with the Input.GetTouch instead of the Input.GetAxis. Hope that helps. Be aware that script is in Javascript, but you shouldn't need the whole script.
