Solved OnPlayerChat and return (C#)

I have a problem if to use in an event of OnPlayerChat return true or false, remaining messages don't come to the general chat

 

a void cannot return true or false.

try

Code:

bool OnPlayerChat(ConsoleSystem.Arg arg)
{
///your stuff
return false
}

 

When using return global chat stops working

 

Code:

object OnPlayerChat(ConsoleSystem.Arg arg)
{
    return null;
}

 

Code:

        void OnPlayerChat(ConsoleSystem.Arg arg)
        {
            BasePlayer player = (BasePlayer)arg.connection.player;
            string message = arg.GetString(0, "text");
            if (arg.connection.authLevel > 0)
            {
                var myClan = FindClanByUser(player.userID.ToString());
                if (myClan == null)
                {
                    SendReply(player, "{0}", _("You are currently not a member of a clan."));
                    return;
                }
                if (string.IsNullOrEmpty(message))
                    return;
                myClan.Broadcast(StripTag(player.displayName, myClan) + ": " + message);
            }
        }

i wanna make, that what admin tells, only goes to clan chat, and what others tell, goes in normal chat, how can i do that?
i though return should avoid sending message to chat, but this way message gets sent to clan chat and to normal chat too.

 

Code:

object OnPlayerChat(ConsoleSystem.Arg arg)
{
 BasePlayer player = (BasePlayer)arg.connection.player;
 string message = arg.GetString(0, "text");
 if (arg.connection.authLevel > 0)
 {
 var myClan = FindClanByUser(player.userID.ToString());
 if (myClan == null)
 {
 SendReply(player, "{0}", _("You are currently not a member of a clan."));
 return false;
 }
 if (string.IsNullOrEmpty(message))
 return false;
 myClan.Broadcast(StripTag(player.displayName, myClan) + ": " + message);
 return false;
 }
 return null;
}
