Coroutine Moving

Questions & Answers
1

My script is intended to move a gameobject towards an object called “cursor.” I’m trying to get the script to launch in a coroutine so it recalculates where it’s supposed to go when I click a second time. I’m pretty sure I’m not doing it right because the gameobject doesn’t move at all. Here is my script:

    public Vector3 startMarker;
    public Vector3 endMarker;
    public GameObject point;
    public float speed;
    private float startTime;
    private float journeyLength;

    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            startMarker = gameObject.transform.position;
            endMarker = GameObject.Find("Cursor").transform.position;
            StartCoroutine(Move());
        }

        IEnumerator Move()
        {
            startTime = Time.time;
            journeyLength = Vector3.Distance(startMarker, endMarker);
            float distCovered = (Time.time - startTime) * speed;
            float fractionOfJourney = distCovered / journeyLength;
            transform.position = Vector3.Lerp(startMarker, endMarker, fractionOfJourney);
        }
    }

It seems like I’m missing something pretty simple, but I can’t spot it… Thanks for helping!

First of all you’re not iterating in your routine so it just runs once, however the rest of the logic didn’t make much sense anyways so I wrote something different. Haven’t tried it but hope it helps.

IEnumerator Move()
{
    float journeyLength = Vector3.Distance(startMarker, endMarker);
    float endTime = Time.time + journeyLength / speed;

    while (Time.time < endTime)
    {
        transform.position = Vector3.Lerp(startMarker, endMarker, Time.time / endTime);
        yield return null;
    }
}
