Why won't my OnGUI() code work?

Questions & Answers

This is my code:

using UnityEngine;
using System.Collections;

public class ButtonScript : MonoBehaviour {
	public Texture2D icon;
	// Use this for initialization
	void Start () {
	
	}

	void OnGUI()
	{
		if (GUI.Button (new Rect (25, 25, 25, 25), icon)) {
						Application.LoadLevel ("LevelSelectScreen");
				}
	}
	
	// Update is called once per frame
	void Update () {
	}

}

I have icon set as a texture but it won’t show on my scene or on the game. Plus, I can’t click on it. What is wrong with this code? I got it from: Unity - Manual: IMGUI Basics
It might help to know that I changed my texture from a sprite to a texture in the inspector.
Thank You!

I tried your code and it works fine. Make sure that your ButtonScript is in the scene you are testing. Even if you don’t have any texture attached to it, you should see the default GUI button at the top left corner.

Make Sure That You Have Assigned a Script to any Object Because In The Script There is no problem at all.

The problem was that i had the first two variables in the rect set to 25 which meant it was 25 times the camera height and width and when i changed that to .5 it worked. Here is my final code(the GUI.backgroundcolor = Color.Clear is to make the buttns invisible):

using UnityEngine;
using System.Collections;

public class ButtonScript : MonoBehaviour {
	public Texture2D icon;
	public float posX; 
	public float posY; 
	public string LevelToLoad;

	// Use this for initialization
	void Start () {

	}

	void OnGUI()
	{
		GUI.backgroundColor = Color.clear;
		if (GUI.Button (new Rect (Screen.width * posX, Screen.height * posY, 200, 40), icon)) {
						Application.LoadLevel (LevelToLoad);
				}
	}
	
	// Update is called once per frame
	void Update () {
	}

}
