保存/取得

保存

PlayerPrefs.SetInt(string key, int num);
PlayerPrefs.SetFloat(string key, float x);
PlayerPrefs.SetString(string key, string str);

取得

int num = PlayerPrefs.GetInt(string key, int default);
float x = PlayerPrefs.GetFloat(string key, float default);
string str = PlayerPrefs.GetString(string key, string default);

PlayerPrefsにBoolはないので作る

   public static bool GetBool(string key, bool defalutValue){
       var value = PlayerPrefs.GetInt(key, defalutValue ? 1 : 0);
       return value == 1;
   }
   public static void SetBool(string key, bool value){
       PlayerPrefs.SetInt(key, value ? 1 : 0);
   }

PlayerPrefsにdoubleがないので作る

    // double start
    public static void SetDouble(string key, double value)
    {
        PlayerPrefs.SetString(key, DoubleToString(value));
    }
    public static double GetDouble(string key, double defaultValue)
    {
        string defaultVal = DoubleToString(defaultValue);
        return StringToDouble(PlayerPrefs.GetString(key, defaultVal));
    }
    public static double GetDouble(string key)
    {
        return GetDouble(key, 0d);
    }

    private static string DoubleToString(double target)
    {
        return target.ToString("R");
    }
    private static double StringToDouble(string target)
    {
        if (string.IsNullOrEmpty(target))
            return 0d;

        return double.Parse(target);
    }
    // double end

getとsetの場合

string viewCntKey = "viewCntKey";
int viewCntDefault = 0;
public int ViewCnt
{
    get { return PlayerPrefs.GetInt(viewCntKey, viewCntDefault); }
    set { PlayerPrefs.SetInt(viewCntKey, value); }
}
