using UnityEngine;
using UnityEngine.UI;

public class GameSetPanel : MonoBehaviour
{
    private static GameSetPanel instance;
    public static GameSetPanel Instance
    {
        get { return instance; }
    }
    private void Awake()
    {
        instance = this;
    }


    Toggle isMuteToggle;
    
    Slider voiceSlider;
    AudioSource gameVolume;
    float lastVolum;
    

    
    void Start()
    {
     
        voiceSlider = transform.Find("GameVolume/VoiceSlider").GetComponent<Slider>();
        isMuteToggle=transform.Find("GameVolume/IsMuteToggle").GetComponent<Toggle>();
        gameVolume = transform.parent.parent.Find("PlayerObj").GetComponent<AudioSource>();
       
        

        voiceSlider.onValueChanged.AddListener(OnSliderValueChange);
        isMuteToggle.onValueChanged.AddListener(IsMute);
        
        voiceSlider.value=30f;
        gameVolume.volume = voice
