Object moving extremely fast when there isn't a target position but direction.

Running into an issue where my object is moving extremely fast when using a direction vs when theres a point to hit from raycast.

public static Vector3 GetShotDirectionCamera(Transform shootTransform, Camera camera, LayerMask mask)
    {
        float distance = 1000;
        Ray ray = camera.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));
        if (Physics.Raycast(ray, out RaycastHit hit, distance, mask))
        {
            return hit.point;
        }
        else
        {
            return ray.GetPoint(distance);
        }
    }

I made sure to normalize the result so im not sure what to do.

newProjectile.Move(shotDirection - ShotOrigin.position.normalized, Profile.ProjectileSpeed);

    public void Move(Vector3 moveDirection, float moveSpeed)
    {
        StartCoroutine(HandleMove(moveDirection, moveSpeed));
    }

private IEnumerator HandleMove(Vector3 moveDirection, float moveSpeed)
    {
        float timeElapsed = 0;
        while ((true))
        {
            transform.position += moveDirection * moveSpeed * Time.deltaTime;
            timeElapsed += Time.deltaTime;
            yield return null;
        }
    }

This

newProjectile.Move(shotDirection - ShotOrigin.position.normalized, Profile.ProjectileSpeed);

Is equivalent to this

var v0 = shotDirection;
var v1 = ShotOrigin.position.normalized;
newProjectile.Move(v0 - v1, Profile.ProjectileSpeed);

You forgot to use parentheses to get the normalized value from the delta.newProjectile.Move((shotDirection - ShotOrigin.position).normalized, Profile.ProjectileSpeed);

That fixed it, thank you!
