Moving box (29390)

I’m working on a game where the player has to pass through a room where some rocks move back and forth, opening and closing the way. I can get the rocks to move using a script with a timer, when it reachs a certain number the rocks changes direction. Is there anyway I can write a script like, “if the rock gets to a certain position it changes direction”?
It needs to b done using C#.

You could do something like-

public Vector3 targetPos1;
public Vector3 targetPos2;

public float moveTime;

float curMoveProportion = 0;
Vector3 targetPos = Vector3.zero;
Vector3 prevPos = Vector3.zero;

// in Start, set up whichever is the first position to be going to
void Start()
{
    targetPos = targetPos2;
    transform.position = targetPos1;
    prevPos = transform.position;
}

// in Update, move the box around between the two points
void Update()
{
    curMoveProportion += (Time.deltaTime / moveTime);
    if(curMoveProportion >= 1)
    {
        if(targetPos == targetPos1)
        {
            targetPos = targetPos2;
        } else {
            targetPos = targetPos1;
        }
        prevPos = transform.position;
        curMoveProportion = 0;
    }
    transform.position = Vector3.Lerp(prevPos, targetPos, curMoveProportion);
}

I’m very new to unity and C#, I tried to understand the code. The problem I’m having now is i don’t know how to set targetPos1 and targerPos2 as a certain position. I tried to convert them into Transform instead of Vector3(so i can create an Empty Object and place it where i want), but this provides an error. How do i set up where my 2 key posisions will be?
