Hi im using the playerprefsx from unity wiki and i cant seem to get it to work. i am attempting to save a bool so that when the player gets to the next level the audio settings save but i cant seem to get it to work

using UnityEngine;
using System.Collections;

public class AudioOnOff : MonoBehaviour 
{
	 bool AudioOff;
	public Texture Off;
	public Texture On;

	void Start()
	{
		PlayerPrefsX.GetBool ("AudioSwitch");
	}

	void OnMouseOver()
	{
		if(Input.GetKeyDown(KeyCode.Mouse0))
		{
			AudioOff = !AudioOff;
		}
	}

	void Update()
	{

		if (AudioOff == true)
		{
			PlayerPrefsX.SetBool ("AudioSwitch",AudioOff); 
		}

		if (AudioOff == false)
		{
			PlayerPrefsX.SetBool ("AudioSwitch",AudioOff) ;
		}

		if (PlayerPrefsX.GetBool ("AudioSwitch") == true)
		{
			renderer.material.mainTexture = Off;
			audio.volume = 0F;
		}
		if (PlayerPrefsX.GetBool ("AudioSwitch") == false)
		{
			renderer.material.mainTexture = On;
			audio.volume = 1F;
		}
	}

i haven’t seen the playerprefsx scripts, but imagine that PlayerPrefsX.GetBool("AudioSwitch"); returns the bool in question so should read

AudioOff = PlayerPrefsX.GetBool ("AudioSwitch");

you could rewrite the whole thing as:

using UnityEngine;
using System.Collections;

public class AudioOnOff : MonoBehaviour
{
    public Texture Off;
    public Texture On;

    private bool _audioOff;

    void Start()
    {
        _audioOff = PlayerPrefsX.GetBool("AudioSwitch");
    }

    void OnMouseOver()
    {
        if (Input.GetKeyDown(KeyCode.Mouse0))
        {
            _audioOff = !_audioOff;
            SetAudioState(); // only save when this actually changes
        }
    }

    private void SetAudioState()
    {
        PlayerPrefsX.SetBool("AudioSwitch", _audioOff);
        renderer.material.mainTexture = _audioOff ? Off : On;
        audio.volume = _audioOff ? 0.0f : 1.0f;
    }
}
