Add specific movement on double click

Questions & Answers
1

I’m sorry if already have an answer to this question here, I searched a lot and tried many things.
I just want the object to move smoothly to a specific distance to the right or left when I double click, but it just disappears and appears in the other place. I already tried to use lerp but it didn’t work.

public float laneSpeed;
    public float changeSpeed;
    
    private float lastClickTime;
    private const float doubleClickTime = 0.2f;
    private float h;
    private float v;
    
    // Update is called once per frame
    void Update()
    {
        h = Input.GetAxis("Horizontal");
        v = Input.GetAxis("Vertical");

        Vector3 direction = new Vector3(h, v, 0);

        transform.position += direction * laneSpeed * Time.deltaTime;

        if (Input.GetKeyDown(KeyCode.D))
        {
            float timeSinceLastClick = Time.time - lastClickTime;
            if(timeSinceLastClick <= doubleClickTime)
            {
                transform.position += new Vector3(10, 0, 0);   //<----
            }
            lastClickTime = Time.time;
        }
        else if (Input.GetKeyDown(KeyCode.A))
        {
            float timeSinceLastClick = Time.time - lastClickTime;
            if (timeSinceLastClick <= doubleClickTime)
            {
                transform.position += new Vector3(-10, 0, 0);  //<----
            }
            lastClickTime = Time.time;
        }
    }

The lerp function has to run each frame to work as you wish, so for example like this:

     public float laneSpeed;
     public float changeSpeed;
     
     private float lastClickTime;
     private const float doubleClickTime = 0.2f;
     private float h;
     private float v;
     Vector3 targetPosition;
     
     // Update is called once per frame
     void Update()
     {
         h = Input.GetAxis("Horizontal");
         v = Input.GetAxis("Vertical");
 
         Vector3 direction = new Vector3(h, v, 0);
 
         transform.position += direction * laneSpeed * Time.deltaTime;
 
         if (Input.GetKeyDown(KeyCode.D))
         {
             float timeSinceLastClick = Time.time - lastClickTime;
             if(timeSinceLastClick <= doubleClickTime)
             {
                 targetPosition = transform.position + new Vector3(10, 0, 0);   //<----
             }
             lastClickTime = Time.time;
         }
         else if (Input.GetKeyDown(KeyCode.A))
         {
             float timeSinceLastClick = Time.time - lastClickTime;
             if (timeSinceLastClick <= doubleClickTime)
             {
                 targetPosition = transform.position + new Vector3(-10, 0, 0);  //<----
             }
             lastClickTime = Time.time;
         }

         transform.position = Vector3.Lerp(transform.position, targetPosition, 0.1);
     }
