Unity游戏本地化c＃

Question

我想为我的游戏添加多种语言支持，目前我正在使用资产商店中的智能本地化。我在第一个场景中有4个按钮用于切换语言，如果选择了一个按钮，浮动“语言”将变为1到4之间的值，语言会发生变化。如果继续下一个场景，“语言”将保存在PlayerPrefs中，如果再次加载脚本，“language”将从PlayerPrefs获取值，因此它应该以之前选择的语言显示文本但是虽然“语言”具有应该改变语言的有效值（1-4），但是文本字段只是空的。有什么想法吗？

继承我的代码：

public class Test : MonoBehaviour  {

    public Text PlayTxt, BackTxt, EarthTxt, HealthTxt, MenuTxt, MissingTxt, RestartTxt, DamageTxt;
    public string playKey = "Play";
    public string earthKey = "Earth";
    public string healthKey = "Health";
    public string menuKey = "Menue";
    public string missingKey = "Missing";
    public string restartKey = "Restart";
    public string damageKey = "Damage";
    public string backKey = "Back";
    public float language;

    void Start(){

         if(PlayerPrefs.HasKey ("language")) {
            language = PlayerPrefs.GetFloat ("language");
        }
    }

    void Update(){

        if (language <= 1) {
            LanguageManager.Instance.ChangeLanguage ("en");
        }
        if (language == 2) {
            LanguageManager.Instance.ChangeLanguage ("de");
        }
        if (language == 3) {
            LanguageManager.Instance.ChangeLanguage ("es");
        }
        if (language == 4) {
            LanguageManager.Instance.ChangeLanguage ("tr");
        }

        PlayTxt.text = "" + LanguageManager.Instance.GetTextValue(playKey);
        BackTxt.text = "" + LanguageManager.Instance.GetTextValue(backKey);
        EarthTxt.text = "" + LanguageManager.Instance.GetTextValue(earthKey);
        HealthTxt.text = "" + LanguageManager.Instance.GetTextValue(healthKey);
        MenuTxt.text = "" + LanguageManager.Instance.GetTextValue(menuKey);
        MissingTxt.text = "" + LanguageManager.Instance.GetTextValue(missingKey);
        RestartTxt.text = "" + LanguageManager.Instance.GetTextValue(restartKey);
        DamageTxt.text = "" + LanguageManager.Instance.GetTextValue(damageKey);

    }

    public void engl(){
        LanguageManager.Instance.ChangeLanguage ("en");
        language = 1;

    }

    public void de(){
        LanguageManager.Instance.ChangeLanguage ("de");
        language = 2;
    }

    public void es(){
        LanguageManager.Instance.ChangeLanguage ("es");
        language = 3;
    }

    public void tr(){
        LanguageManager.Instance.ChangeLanguage ("tr");
        language = 4;
    }

    void OnDestroy(){
        PlayerPrefs.SetFloat ("language", language);

    }
 }
