扩展cocos creator 中的 localstorage

 

问题：cc中的localstorage仅能保存字符，用typescript开发时不便于各场景的应用

扩展内容如下：

1.支付默认值

2.增加string bool number强类型

3.当set时，写入localstorage，当get时，取缓存里里的数据

export class LocalStorageValue {

    //声音音量
    private static _soundVolume: number = null;
    public static get SoundVolume() {
        if (this._soundVolume == null)
            this._soundVolume = LocalStorage.GetNumber('SoundVolume', 1)
        return this._soundVolume;
    }
    public static set SoundVolume(value) {
        this._soundVolume = value
        LocalStorage.SetNumber('SoundVolume', this._soundVolume)
    }

    //音乐音量
    private static _musicVolume: number = null;
    public static get MusicVolume() {
        if (this._musicVolume == null)
            this._musicVolume = LocalStorage.GetNumber('MusicVolume', 1)
        return this._musicVolume;
    }
    public static set MusicVolume(value) {
        this._musicVolume = value
        LocalStorage.SetNumber('MusicVolume', this._musicVolume)
    }

  

    //手机登录账号
    private static _phoneLoginAccount: string = null;
    public static get PhoneLoginAccount() {
        if (this._phoneLoginAccount == null)
            this._phoneLoginAccount = LocalStorage.GetString('PhoneLoginAccount', '')
        return this._phoneLoginAccount;
    }
    public static set PhoneLoginAccount(value) {
        this._phoneLoginAccount = value
        LocalStorage.SetString('PhoneLoginAccount', this._phoneLoginAccount)
    }

    //手机登录密码
    private static _phoneLoginPassword: string = null;
    public static get PhoneLoginPassword() {
        if (this._phoneLoginPassword == null)
            this._phoneLoginPassword = LocalStorage.GetString('PhoneLoginPassword', '')
        return this._phoneLoginPassword;
    }
    public static set PhoneLoginPassword(value) {
        this._phoneLoginPassword = value
        LocalStorage.SetString('PhoneLoginPassword', this._phoneLoginPassword)
    }

        return this._guestLoginAccount;

    public static set GuestLoginAccount(value) {
        this._guestLoginAccount = value
        LocalStorage.SetString('GuestLoginAccount', this._guestLoginAccount)

    private static _IsAutoLogin: boolean = null;
    public static get IsAutoLogin() {
        if (this._IsAutoLogin == null)
            this._IsAutoLogin = LocalStorage.GetBool('IsAutoLogin', false)
        return this._IsAutoLogin;
    }
