Player Swipe Movement Controller like subway surfer using Character Controller in Unity3D? - unity3d

Question

I am trying to make a player movement controller like subway surfer using Character Controller, every thing is working fine with keyboard but I am getting an issue in swipe. When I swipe its moving only one frame. And also I want player to go left and right while player in air(Jumping). Please help.
Here is my code:
using UnityEngine;
using System.Collections;
public class PlayerControllerScript : MonoBehaviour
{
public float speed = 8.0F;
public float jumpSpeed = 16.0F;
public float gravity = 80.0F;
private Vector3 moveDirection = Vector3.zero;
public int laneNumber = 1;
public int lanesCount = 3;
bool didChangeLastFrame = false;
public float laneDistance = 2;
public float firstLaneXPos = -2;
public float deadZone = 0.1f;
public float sideSpeed = 12;
private bool Right = false;
private bool Left = false;
void Update()
{
CharacterController controller = GetComponent<CharacterController>();
float input = Input.GetAxis("Horizontal");
if (controller.isGrounded) {
if (Mathf.Abs(input) > deadZone)
{
if (!didChangeLastFrame)
{
didChangeLastFrame = true;
laneNumber += Mathf.RoundToInt(Mathf.Sign(input));
if (laneNumber < 0) laneNumber = 0;
else if (laneNumber >= lanesCount) laneNumber = lanesCount - 1;
}
}
else
{
didChangeLastFrame = false;
moveDirection = new Vector3(0, 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton("Jump") || SwipeManager.IsSwipingUp())
moveDirection.y = jumpSpeed;
}
}
if (Left)
moveDirection.x = -jumpSpeed;
if (Right)
moveDirection.x = jumpSpeed;
if (SwipeManager.IsSwipingLeft())
{
Left = true;
Right = false;
}
if (SwipeManager.IsSwipingRight())
{
Right = true;
Left = false;
}
Vector3 pos = transform.position;
pos.x = Mathf.Lerp(pos.x, firstLaneXPos + laneDistance * laneNumber, Time.deltaTime * sideSpeed);
transform.position = pos;
moveDirection.y -= gravity * Time.deltaTime;
controller.Move(moveDirection * Time.deltaTime);
}
}

I think,
if (Input.GetButton("Jump") || SwipeManager.IsSwipingUp())
moveDirection.y = jumpSpeed;
must be outside the if(controller.isGrounded) block. So, you jump regardless of gravity.
This is the final code;
using UnityEngine;
using System.Collections;
public class PlayerControllerScript : MonoBehaviour
{
public float speed = 8.0F;
public float jumpSpeed = 16.0F;
public float gravity = 80.0F;
private Vector3 moveDirection = Vector3.zero;
public int laneNumber = 1;
public int lanesCount = 3;
bool didChangeLastFrame = false;
public float laneDistance = 2;
public float firstLaneXPos = -2;
public float deadZone = 0.1f;
public float sideSpeed = 12;
private bool Right = false;
private bool Left = false;
void Update()
{
CharacterController controller = GetComponent<CharacterController>();
float input = Input.GetAxis("Horizontal");
if (controller.isGrounded) {
if (Mathf.Abs(input) > deadZone)
{
if (!didChangeLastFrame)
{
didChangeLastFrame = true;
laneNumber += Mathf.RoundToInt(Mathf.Sign(input));
if (laneNumber < 0) laneNumber = 0;
else if (laneNumber >= lanesCount) laneNumber = lanesCount - 1;
}
}
else
{
didChangeLastFrame = false;
moveDirection = new Vector3(0, 0, Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
}
}
if (Input.GetButton("Jump") || SwipeManager.IsSwipingUp())
moveDirection.y = jumpSpeed;
if (Left)
moveDirection.x = -jumpSpeed;
if (Right)
moveDirection.x = jumpSpeed;
if (SwipeManager.IsSwipingLeft())
{
Left = true;
Right = false;
}
if (SwipeManager.IsSwipingRight())
{
Right = true;
Left = false;
}
Vector3 pos = transform.position;
pos.x = Mathf.Lerp(pos.x, firstLaneXPos + laneDistance * laneNumber, Time.deltaTime * sideSpeed);
transform.position = pos;
moveDirection.y -= gravity * Time.deltaTime;
controller.Move(moveDirection * Time.deltaTime);
}
}
