A Fix To CS0246?

So I Had To Fix This Script I Think I did What They Ask I Still Get This Errror

error CS0246: The type or namespace name 'UI' could not be found (are you missing a using directive or an assembly reference?)

using System;
using UnityEngine;

#pragma warning disable 618
namespace UnityStandardAssets.Utility
{
public class SimpleActivatorMenu : MonoBehaviour
{
// An incredibly simple menu which, when given references
// to gameobjects in the scene
public UI camSwitchButton;
public GameObject[] objects;


private int m_CurrentActiveObject;


private void OnEnable()
{
// active object starts from first in array
m_CurrentActiveObject = 0;
camSwitchButton.text = objects[m_CurrentActiveObject].name;
}


public void NextCamera()
{
int nextactiveobject = m_CurrentActiveObject + 1 >= objects.Length ? 0 : m_CurrentActiveObject + 1;

for (int i = 0; i < objects.Length; i++)
{
objects.SetActive(i == nextactiveobject);
}

m_CurrentActiveObject = nextactiveobject;
camSwitchButton.text = objects[m_CurrentActiveObject].name;
}
}
}[/code]


Yet Don't Know I Might Have Re Learned Coding But This Puzzled Me

 

Kudos for using half the CODE tag. Please use both of them

I will presume that you want to refer to a Button. So this

should be something like this:

Code (CSharp):

1. using UnityEngine.UI;
2. [...]
3. public Button camSwitchButton;
