How can i stop the object from keep moving when it's getting to it's original position ?

Scripting

I have a problem with the bool variable landShip i can’t figure out how to make it like a switch in the Update function and when i click on the L key. I want that when i click on the L key and only when it’s getting back to it’s originalPosition then stop the object.

using UnityEngine;
using System.Collections;

public class Control : MonoBehaviour
{
    public int rotationSpeed = 75;
    public int movementspeed = 10;
    public int thrust = 10;

    private bool isPKeyDown = false;
    private float acceleration = .0f;
    private Vector3 previousPosition = Vector3.zero;
    private Rigidbody _rigidbody;
    private Vector3 originalPosition;
    private Quaternion originalRotation;
    private bool landShip = false;

    // Use this for initialization
    void Start()
    {
        originalPosition = transform.position;
        originalRotation = transform.rotation;

        _rigidbody = GetComponent<Rigidbody>();
        Debug.Log("Acc Speed: " + thrust);
    }

    // Update is called once per frame
    void Update()
    {

        var v3 = new Vector3(Input.GetAxis("Vertical"), Input.GetAxis("Horizontal"), 0.0f);
        transform.Rotate(v3 * rotationSpeed * Time.deltaTime);
        if (landShip == false)
        {
            transform.position += transform.forward * Time.deltaTime * movementspeed;
        }
       
        if (Input.GetKey(KeyCode.Z))
            transform.Rotate(Vector3.forward * rotationSpeed * Time.deltaTime);

        if (Input.GetKey("p"))
        {
            isPKeyDown = Input.GetKey("p");
            float distance = Vector3.Distance(previousPosition, transform.position);
            acceleration = distance / Mathf.Pow(Time.deltaTime, 2);

            previousPosition = transform.position;
            _rigidbody.AddRelativeForce(0f, 0f, thrust, ForceMode.Acceleration);
        }

        if (Input.GetKey("l"))
        {
            landShip = true;
        }
        if (landShip == true)
        {
            StartCoroutine(TurnShip(transform, transform.eulerAngles, new Vector3(0, 180, 0), 1));
            if (transform.position == originalPosition)
            {
                Debug.Log("At original position " + originalPosition);
                //landShip = true;
            }
        }
    }

    IEnumerator TurnShip(Transform ship, Vector3 startAngle, Vector3 endAngle, float smooth)
    {
        float lerpSpeed = 0;

        while (lerpSpeed < 1)
        {
            ship.eulerAngles = Vector3.Lerp(startAngle, endAngle, lerpSpeed);
            lerpSpeed += Time.deltaTime * smooth;
            yield return null;
        }
    }

    void OnGUI()
    {
        if (isPKeyDown)
        {
            GUI.Label(new Rect(100, 100, 200, 200), "Acc Speed: " + acceleration);
        }
    }
}

The problem is here:

[code]
if (landShip == false)
        {
            transform.position += transform.forward * Time.deltaTime * movementspeed;
        }

And here

if (Input.GetKey("l"))
        {
            landShip = true;
        }
        if (landShip == true)
        {
            StartCoroutine(TurnShip(transform, transform.eulerAngles, new Vector3(0, 180, 0), 1));
            if (transform.position == originalPosition)
            {
                Debug.Log("At original position " + originalPosition);
                //landShip = true;
            }
        }

Can’t figure out how to use the landShip bool.

I think the problem you’re asking about is elsewhere, but you should not be using Euler angles. They’ll come back and bite you later.

Your main issue is that your ship is going to cruise right past your target point, because using == on anything float-based (including Vector3) is not going to be reliable - especially if you’re moving it with a value like Time.deltaTime. Probably want to use a “nearest approach” algorithm as described on that page.
