Enemy AI scripting

I creat one cube and Cylinder. I want to cube automatically find Cylinder. I need to write Enemy AI.

This my script.

using UnityEngine; using System.Collections;

public class EnemyAI : MonoBehaviour {
public Transform target;
public int moveSpeed;
public int rotationSpeed;

private Transform Cube

void Awake() {
    Cube = transform;

// Use this for initialization
void Start () {
    GameObject  = GameObject.FindGameObjectWithTag("Cylinder");

    target = transform("Cylinder");


// Update is called once per frame
void Update () {



I have wrong.What is mean?

Assets/NewBehaviourScript.js(16,6): UCE0001: ';' expected. Insert a semicolon at the end.

private Transform Cube;

The las ';' is missing

But later on you will have problems with 'Cube' since it is a reserved name
