I tried fixing "Using GUiTexture has been removed, use UI.Image instead" But it wont work

Help!! I have been trying to fix this for hours now and can’t find out how to do it

The original code was this

using UnityEngine;
using UnityEngine.SceneManagement;

public class LoadGame : MonoBehaviour {

public Texture2D playNormal;
public Texture2D playHover;

void OnMouseEnter(){
	GetComponent<GUITexture>().texture = playHover;
}

void OnMouseExit(){
	GetComponent<GUITexture>().texture = playNormal;
}

void OnMouseDown()
{
	//Nilupul
	//SaveGame.Instance.Load();
	SaveGame.Instance.IsSaveGame = true;
	SceneManager.LoadScene ("Test");
}

// Use this for initialization
void Start () {
	
}

}

I tried doing what it told me “Use UI.Image instead” And still didnt work, it just said "the type or namespace “UI could not be found (are you missing a using directive or an assembly reference?”

This is the code after I tried fixing it

using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class LoadGame : MonoBehaviour {

public Texture2D playNormal;
public Texture2D playHover;

void OnMouseEnter(){
	GetComponent<UI.Image>().texture = playHover;
}

void OnMouseExit(){
	GetComponent<UI.Image>().texture = playNormal;
}

void OnMouseDown()
{
	//Nilupul
	//SaveGame.Instance.Load();
	SaveGame.Instance.IsSaveGame = true;
	SceneManager.LoadScene ("Test");
}

// Use this for initialization
void Start () {
	
}

}
,This is the code

using UnityEngine;
using UnityEngine.SceneManagement;

public class LoadGame : MonoBehaviour {

public Texture2D playNormal;
public Texture2D playHover;

void OnMouseEnter(){
	GetComponent<GUITexture>().texture = playHover;
}

void OnMouseExit(){
	GetComponent<GUITexture>().texture = playNormal;
}

void OnMouseDown()
{
	//Nilupul
	//SaveGame.Instance.Load();
	SaveGame.Instance.IsSaveGame = true;
	SceneManager.LoadScene ("Test");
}

// Use this for initialization
void Start () {
	
}

}

This is what I did that it told me to, but still didn’t work, pls help

using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class LoadGame : MonoBehaviour {

public Texture2D playNormal;
public Texture2D playHover;

void OnMouseEnter(){
	GetComponent<UI.Image>().texture = playHover;
}

void OnMouseExit(){
	GetComponent<UI.Image>().texture = playNormal;
}

void OnMouseDown()
{
	//Nilupul
	//SaveGame.Instance.Load();
	SaveGame.Instance.IsSaveGame = true;
	SceneManager.LoadScene ("Test");
}

// Use this for initialization
void Start () {
	
}

}

All it said after doing what I was told was “The type or namespace name UI could not be found (are you missing a using directive or an assembly reference?)”

You only need

GetComponent<Image>()

Also, use GetComponent on Start, set up a reference, and use that later.

// Use this on Start
Image img = GetComponent<Image>();

// Use this whenever you want to access the Image component
img.texture = playHover;
img.texture = playNormal;

Keep in mind that it works only if your GameObject has an Image component on it.
