Solved Automatic language switching for incoming players?

yep, i have Russian language files, if i write in chat "/lang ru" - it's work.

 

I see the sense in it.
Where i can find information about: lang, player.ConsoleMessage and other oxide functions?
and why this code works for other people but not for me?

Code:

lang.SetLanguage("ru", player.UserIDString);

maybe I did not connect the necessary libraries?

It's all code:

Code:

namespace Oxide.Plugins
{
    [Info("Lang", "hulimontana", 0.1)]
    [Description("Auto change language")]    class Lang : RustPlugin
    {
        void OnPlayerInit(BasePlayer player)
        {
            if (player == null || player.net == null || player.net.connection == null) return;
            string ply_lang = player.net.connection.info.GetString("global.language", null);
            // returns a shortcode like 'en'
            if (ply_lang != null)
            {
                //do whatelse example
                string lng = ply_lang.Substring(0, 1);
                Puts($"Player {player.displayName} has the language {lng}");
                lang.SetLanguage(lng, player.UserIDString);
            }
        }
    }
}

 

what you mean about compilation? i just create .txt file and rename it in "lang.cs".
if you about loading plugin:

 

Code:

public static string GetLanguage(this Connection connection)
{
    bool flag = connection != null;
    string result;
    if (flag)
    {
        result = connection.info.GetString("global.language", "en").ToUpper();
    }
    else
    {
        result = "EN";
    }
    return result;
}
