[noob] I have a script that theoretically should manage movement of a 2D GameObject...

Before I get to the question, I am an ultra-level noob, and this is my first post.

I’m probably breaking about a million best practice rules and misunderstanding many basic principles. Any corrections, whether about the code or the question, would be greatly appreciated

I have this script, which I thought would move a gameobject one unit slowly enough to show an animation. I have a 16x32 pixel sprite attached to the GameObject and the pixel-units ratio is set to 16p to 1 unit.

However, I am getting a CS0161 on line 16 of the code. I googled the error code, but I was unable to figure exactly how the problem worked and how to fix it.

If someone wouldn’t mind looking at this and explaining why this doesn’t work I would greatly appreciate it

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class NewBehaviourScript1 : MonoBehaviour {
    //Animation Delay
    public float animFrameDelay = .05f;
    //Adds a simple(r) method of adding a delay
    IEnumerator WaitFunc(float time)
        yield return new WaitForSeconds(time);
    //moves the object
    IEnumerator ObjectMover(float x, float y, float z)
        int i = 0;
        while (i < 16)
            Vector3 temp = new Vector3(x, y, z);
            transform.position += temp;

    // Use this for initialization
    void Start () {
    // Update is called once per frame
    void Update () {
        bool up = Input.GetKey(KeyCode.UpArrow);
        bool down = Input.GetKey(KeyCode.DownArrow);
        bool left = Input.GetKey(KeyCode.LeftArrow);
        bool right = Input.GetKey(KeyCode.RightArrow);
        float TileSize = .0625F;


        if (up)
            StartCoroutine(ObjectMover(0, TileSize, 0));
        if (down)
            StartCoroutine(ObjectMover(0, -TileSize, 0)); ;
        if (left)
            StartCoroutine(ObjectMover(-TileSize, 0, 0));

        if (right)
            StartCoroutine(ObjectMover(TileSize, 0, 0));


Ok, this was a mess, sorry about the spaghetti everyone.

I wound up using Vector3.MoveTorwards and Time.DeltaTime
