Move Transform to Target in X seconds

Questions & Answers

public Transform a;
public Transform target;
public float x = 30f; //amount of seconds for A to reach Target

I have a Transform A and a Transform target. My goal is to make A reach Target in x seconds. I have tried both Vector3.Lerp and Vector3.MoveTowards but can not figure out the problem.

Ok so Lerp will move you there in a guaranteed amount of time, but you need to record the starting position - which is trickier in Update.

   float t;
   Vector3 startPosition;
   Vector3 target;
   float timeToReachTarget;

    void Start()
    {
            startPosition = target = transform.position;
    }

    void Update() 
    {
            t += Time.deltaTime/timeToReachTarget;
            transform.position = Vector3.Lerp(startPosition, target, t);
    }

    public void SetDestination(Vector3 destination, float time)
    {
           t = 0;
           startPosition = transform.position;
           timeToReachTarget = time;
           target = destination; 
    }

Move any object to any place at any speed (units/seconds) or in any time – all done without using Update:

 StartCoroutine (MoveOverSeconds (gameObject, new Vector3 (0.0f, 10f, 0f), 5f));

 public IEnumerator MoveOverSpeed (GameObject objectToMove, Vector3 end, float speed){
	// speed should be 1 unit per second
	while (objectToMove.transform.position != end)
	{
		objectToMove.transform.position = Vector3.MoveTowards(objectToMove.transform.position, end, speed * Time.deltaTime);
		yield return new WaitForEndOfFrame ();
	}
}

public IEnumerator MoveOverSeconds (GameObject objectToMove, Vector3 end, float seconds)
{
	float elapsedTime = 0;
	Vector3 startingPos = objectToMove.transform.position;
	while (elapsedTime < seconds)
	{
		objectToMove.transform.position = Vector3.Lerp(startingPos, end, (elapsedTime / seconds));
		elapsedTime += Time.deltaTime;
		yield return new WaitForEndOfFrame();
	}
	objectToMove.transform.position = end;
}

Using — public IEnumerator MoveToPosition(Transform transform, Vector3 position, float timeToMove)
{
var currentPos = transform.position;
var t = 0f;
while(t < 1)
{
t += Time.deltaTime / timeToMove;
transform.position = Vector3.Lerp(currentPos, position, t);
yield return null;
}
}

This code does not work as described above by “whydoidoit”

The code makes an object Move in 4-5 seconds, when the INPUT is 1.
