Playerprefs 似乎不起作用

Question

现在我的想法有点混乱，因为我是 c# 的菜鸟。 顺便一提 。我正在做的是将我的设置保存在我使用切换创建的菜单中。 这是我的代码：

[SerializeField]
GameObject Option;
[SerializeField]
Button btn,btn2;
[SerializeField]
GameObject open, close;

[SerializeField]
GameObject[] opt;
bool startFinding = false;

//settings
bool livestream;
bool rendering;
bool fog;
bool cameraeffect;

int live;
void Start()
{

    Option.SetActive(false);
    Button popUp = btn.GetComponent<Button>();
    Button popUp2 = btn2.GetComponent<Button>();
    popUp.onClick.AddListener(PopUpOption);
    popUp2.onClick.AddListener(ClosePopUp);

}

void Update()
{
    if (startFinding)
    {
        StartCoroutine(GameOptions());
    }
}

IEnumerator GameOptions()
{

    if (PlayerPrefs.HasKey("SaveSettings"))
    {
        ActivateSettings();
        Debug.Log("Theres a data");
    } else
    {
        Debug.Log("Oops sorry there was no data");
    }

    //Get All the tags
    opt = GameObject.FindGameObjectsWithTag("MobileOptions");
    //fog , camera , livestream, rendering

    if (opt[0].GetComponent<Toggle>().isOn == true && opt[1].GetComponent<Toggle>().isOn == true)
    {
        Debug.Log("Disable first the check box then choose only 1 option between" + "'rendering'"+ "and" + "'livestreaming'");
    }
    //Livestreaming
    if (opt[0].GetComponent<Toggle>().isOn == true)
    {
        Debug.Log("Livestreaming Activate");
        livestream = true;
    } else 
    {
        Debug.Log("Livestreaming Deactivate");
        livestream = false;
    }
    //Rendering
    if (opt[1].GetComponent<Toggle>().isOn == true)
    {
        rendering = true;
        Debug.Log("Rendering Activate");
    } else
    {
        Debug.Log("Rendering Deactivate");
        rendering = false;
    }
    //Fog

    if (opt[2].GetComponent<Toggle>().isOn == true)
    {
        fog = true;
        Debug.Log("Fog Activated");
    } else
    {
        Debug.Log("Fog Deactivated");
        fog = false;
    }

    //Camera Effect
    if (opt[3].GetComponent<Toggle>().isOn == true)
    {
        cameraeffect = true;
        Debug.Log("Camera Effect Activated");
    } else {
        Debug.Log("Camera Effect Deactivated");
        cameraeffect = false;
    }

    SaveSettings();

    yield return null;
}

void SaveSettings()
{
    try { 
        //convert the bool to int
        live = livestream ? 1 : 0;
        PlayerPrefs.SetInt("SaveSettings", live);
        PlayerPrefs.Save();
    }
    catch (Exception ex)
    {
        Debug.LogError("Exception :" + ex);
    }
}
 void ActivateSettings()
{
    live = PlayerPrefs.GetInt("SaveSettings");
}

我猜我的 playerprefs 不工作，但我的 debug.log 说它有数据。它搞砸了，或者我只是错过了一些关于 playerprefs 的东西。有人可以指出我做错了什么。我不想被困在这里。

Answer 1

正如您之前问过的here，您在Update 方法中调用StartCoroutine(GameOptions()) 是错误的！那是因为你一遍又一遍地调用SaveSettings()，因为PlayerPrefs.SetInt("SaveSettings", live) 在Update 方法中调用了太多次

Answer 2

我做的是这个，我知道这个协程并不是什么大问题。

[SerializeField]
Button openButton, closeButton;
[SerializeField]
GameObject OPTION_UI;//parent
[SerializeField]
GameObject open_option_button, close_option_button;

[SerializeField]
GameObject[] settings;

[SerializeField]
Toggle[] toggle;

bool Found = false;
 void Start()
{
    OPTION_UI.SetActive(false);
    Button OPENBUTTON = openButton.GetComponent<Button>();
    Button CLOSEBUTTON = closeButton.GetComponent<Button>();
    OPENBUTTON.onClick.AddListener(OpenUI);
    CLOSEBUTTON.onClick.AddListener(CloseUI);

    toggle[2].isOn = true;
    //fog
    if (PlayerPrefs.GetInt("SaveFog") == 1)
    {
        toggle[0].isOn = true;
    }
    else
    {
        toggle[0].isOn = false;
    }
    //camera
    if (PlayerPrefs.GetInt("SaveCamera") == 1)
    {
        toggle[1].isOn = true;
    }
    else
    {
        toggle[1].isOn = false;
    }
    //livestreaming
    if (PlayerPrefs.GetInt("SaveLiveStream") == 1)
    {
        toggle[2].isOn = true;
    }
    else
    {
        toggle[2].isOn = false;
    }
    //rendering
    if (PlayerPrefs.GetInt("SaveRendering") == 1)
    {
        toggle[3].isOn = true;
    }
    else
    {
        toggle[3].isOn = false;
    }
} 


 void Update()
{
    if (Found)
    {
        StartCoroutine(GameOptions());
    } else
    { 
        StopCoroutine(GameOptions());
    }
}

IEnumerator GameOptions()
{

    /*
     * fog , camera
     * livestream, rendering
     * */

    //get the options
    settings = GameObject.FindGameObjectsWithTag("MobileOption");

    //fog
    if (toggle[0].isOn == true)
    {
        PlayerPrefs.SetInt("SaveFog", 1);
    } else
    {
        PlayerPrefs.SetInt("SaveFog", 0);
    }

    //camera
    if (toggle[1].isOn == true)
    {
        PlayerPrefs.SetInt("SaveCamera", 1);
    } else
    {
        PlayerPrefs.SetInt("SaveCamera", 0);
    }
    //livestream
    if (toggle[2].isOn == true)
    {
        PlayerPrefs.SetInt("SaveLiveStream" , 1);
    } else
    {
        PlayerPrefs.SetInt("SaveLiveStream", 0);
    }
    //rendering
    if (toggle[3].isOn == true)
    {
        PlayerPrefs.SetInt("SaveRendering", 1);
    } else
    {
        PlayerPrefs.SetInt("SaveRendering", 0);
    }

    yield return null;
}


//activate UI
void OpenUI()
{

    Found = true;
    open_option_button.SetActive(false);
    close_option_button.SetActive(true);
    OPTION_UI.SetActive(true);

}
//deactivate UI
void CloseUI()
{
    Found = false;
    open_option_button.SetActive(true);
    close_option_button.SetActive(false);
    OPTION_UI.SetActive(false);

}
