Wait for a coroutine to finish before moving on with the function C# Unity

Question

I was working on making a unit move through a grid in Unity2d. I got the movement to work without problems. I would want the function MovePlayer to wait until the coroutine

Answer 1

You can not wait for a coroutine in a function in the main thread, otherwise your game will freeze until your function ends.

Why don't you call your next step at the end of your coroutine?

private IEnumerator SmoothMovement(List path)
{
    float step = speed * Time.deltaTime;

    for (int i = 0; i < path.Count; i++)
    {
        targetPosition = new Vector3(path[i].coordinatesX, path[i].coordinatesY, 0f);

        float sqrRemainingDistance = (transform.position - targetPosition).sqrMagnitude;

        while (sqrRemainingDistance > float.Epsilon)
        {
            transform.position = Vector3.MoveTowards(transform.position, targetPosition, step);
            sqrRemainingDistance = (transform.position - targetPosition).sqrMagnitude;
            yield return null;
        }

        position = transform.position;
    }
    //Next Step
}
