Games Help On Transferring From Pc Controls To Mobile Controls.

Hey, I am new to this. I thought i might try and make an android game and release it in a few weeks. So, I have followed a tutorial online that made the type of game I wanted to make. I figured that it would be somewhat easy to change the controls from PC to Mobile. I was wrong. I have searched everywhere and I cannot find a way to convert my game to mobile. I downloaded a joystick and Lean Touch +, but I could not figure it out. The game is an endless runner and the character only moves up and down within a certain limit controlled by a swipe in the given direction. So, if I swipe up, then the player moves up. I need Help! I want to release this game in a few weeks! I'm freaking out!!


public class Player : MonoBehaviour
{
private Vector2 targetPos;
public float Yincrements;
public float speed;
public float maxHeight;
public float minHeight;
public Animator animator;
public int health = 3;
public Text healthDisplay;
public GameObject gameOver;
public GameObject popSound;
private void Update()
{
healthDisplay.text = health.ToString();
if (health <= 0)
{
gameOver.SetActive(true);
Destroy(gameObject);
}
transform.position = Vector2.MoveTowards(transform.position, targetPos, speed * Time.deltaTime);
if (Input.GetKeyDown(KeyCode.UpArrow) && transform.position.y < maxHeight)
{
Instantiate(popSound, transform.position, Quaternion.identity);
animator.Play("PLayer_Fly_up");
targetPos = new Vector2(transform.position.x, transform.position.y + Yincrements);
}
else if (Input.GetKeyDown(KeyCode.DownArrow) && transform.position.y > minHeight)
{
Instantiate(popSound, transform.position, Quaternion.identity);
animator.Play("Player_Fly_down");
targetPos = new Vector2(transform.position.x, transform.position.y - Yincrements);
}
}
}
