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<Node> 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
}
