Hello everyone!

4 days ago i started working with unity. I am developing a android app for it. i have heard that using multiple scenes isn’t really effective for android games so i am looking for a way around it. So right now i have a main menu. with theme music and 2 buttons. 1 for options one for play. i made it so that the play button loads my game scene wich works. however i want it so that when i press the options button it clears the current gui and shows the list of options. what is the best way to do this?

Thanks in advance!

at the moment i have this script running on my camera

using UnityEngine;
using System.Collections;

public class GuiMainMenu : MonoBehaviour {
	void Start() {
		audio.Play ();
	}
	void OnGUI () {
		if(GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - -50, 200, 50), "Play")) {
			Application.LoadLevel ("Game");
		}
		if(GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 10, 200, 50), "Settings")) {

		}

	}
}

using UnityEngine;
using System.Collections;

public class GuiMainMenu : MonoBehaviour {
public bool button1 = true;
public bool button2 = true;
    void Start() {
       audio.Play ();
    }
    void OnGUI () {
       if (button1) {
       if(GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - -50, 200, 50), "Play")) {
         Application.LoadLevel ("Game");
         button1 = false;
        button2 = false;
       }
}
       if (button2)
       if(GUI.Button(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 10, 200, 50), "Settings")) {
        //goto settings tab/box/scene
        button1 = false;
        button2 = false;
 
       }
 }
    }
}

assuming thats what u mean?

then if u have a back button when, say the settings is opened, u could reset it to equal true…
