How to smooth movement object in one-axis?

Questions & Answers

Hello everyone, so i have a problem. I already can move the object by +2f, and set a limit position, But there is a problem. The problem is that i cant move it smoothly, i dont know how to do it, since im still a newbie. Is there anyone willing to help me? Thank you!
Also i will give the code.

CODE:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class test : MonoBehaviour
{
public float stepHeight = 2f;
public float minY, maxY;

// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    if (Input.GetKeyDown(KeyCode.UpArrow))
    {
        transform.position = new Vector3(transform.position.x, transform.position.y + stepHeight, transform.position.z);
    }
    if (Input.GetKeyDown(KeyCode.DownArrow))
    {
        transform.position = new Vector3(transform.position.x, transform.position.y - stepHeight, transform.position.z);
    }

    transform.position = new Vector3(transform.position.x, Mathf.Clamp(transform.position.y, minY, maxY), transform.position.z);
}

}

I’m not sure if that’s what you want, but if I’m right, you should use transform.Translate.

 //speed of your object
 public float speed = 5f;
 
 //Time.deltaTime makes your speed independent from the player's framerate.

 void Update(){
      transform.Translate(speed * Vector3.up * Input.GetAxis("Vertical") * Time.deltaTime);
 }

Also, remember that Input.GetKeyDown only triggers when the key is pressed down. Not when it’s hold down or anything similar.
