MOVE GameObject to point A to B and to B to A

Question

Hello, try to move object "blinds" to point A to B and then to B to A

my code work for A to B (slowly) but dont work for B to A (teleportation)

do you have anny issue ? my code here ↓↓

using UnityEngine;

using System.Collections;

//using SimpleJSON;

public class blind_move : MonoBehaviour

{

 public GameObject blinds;
 private Vector3 Open;
 public Vector3 Close;
 public float distance = 5f;
 public float speed = 5;
 public float currentDistance;
 private bool keyHit;
 private bool keyHit2;

 void Start()
 {
     Open = blinds.transform.position;
     Close = blinds.transform.position + Vector3.down * distance;
 }

 void Update()
 {
     if (Input.GetKeyDown(KeyCode.U))
     {
         keyHit = true;
    
     }
     if (keyHit == true)
     {
         currentDistance += Time.deltaTime;
       if (currentDistance >= speed)
         {
             currentDistance = speed;
         }
         float Perc = currentDistance / speed;
         blinds.transform.position = Vector3.Lerp(Open, Close, Perc);

     }

     
      if (Input.GetKeyDown(KeyCode.D)) 
     {
         keyHit2 = true;
      }
     if (keyHit2 == true)
     {
         currentDistance += Time.deltaTime;
         if (currentDistance <= speed)
         {
             currentDistance = speed;
         }
         float Perc = currentDistance / speed;
         blinds.transform.position = Vector3.Lerp(Close, Open, Perc);
        
     }
     
    
 }

}

What about re-writing your code to just this

 using UnityEngine;
 
 public class blind_move : MonoBehaviour
 {
     public Transform blinds;
 
     public float distance = 5f;
     public float speed = 5f;
 
     private bool movingUp;
     private bool movingDown;
 
     void Update()
     {
         if (Input.GetKeyDown(KeyCode.U))
             movingUp = true;
         else if (Input.GetKeyDown(KeyCode.D))
             movingDown = true;
 
         var step = speed * Time.deltaTime;
 
         if (movingUp)
             blinds.position = Vector3.Lerp(blinds.position, blinds.position + Vector3.up * distance, step);
         else if (movingDown)
             blinds.position = Vector3.Lerp(blinds.position, blinds.position + Vector3.down * distance, step);
     }
 }

Note that you'll have to re-assign Blinds in the inspector, as this time it's a Transform instead of a GameObject.

the object doesn't stop in a position its not really working

Look at misher's anwser. Add two more Transforms, and replace Vector3.Lerp with Vector3.MoveTowards. Make it so that if you're moving up, the blind is moving towards the top transform, and if it's moving down, it's moving towards the bottom transform.

You better create 2 empty game objects (points A and B) and use them as references and you also can physically see them in the Editor. Your object can be in 3 states:

moving to A
moving to B
stay where it is.

Depending on which state it is, you do:

Smoothly moving to the A
Smoothly moving to the B
Do nothing

Code for moving:

 void Update() {
     float step = speed * Time.deltaTime;
     transform.position = Vector3.MoveTowards(transform.position, target.position, step);
 }

Assuming this script run on the object which you want to move. Target transform should be changed dynamically, and it is A or B transform references.

This is would be the correct way of doing it.

MOVE GameObject to point A to B and to B to A
