For example i use this in my dll:

using System.Collections.Generic;
using System.Globalization;
using maddox.game;
using maddox.game.world;

namespace COD
{
    public static class Message
    {
        static readonly IGamePlay GamePlay = Strategy.THIS.GamePlay;


        public static void ToChatbar(string msg, params object[] args)
        {
            GamePlay.gpLogServer(null, msg, args);
        }


        public static void ToChatbar(Player player, string msg, params object[] args)
        {
            if (player != null)
                GamePlay.gpLogServer(new[] { player }, msg, args);
        }


        public static void ToChatbar(int army, string msg, params object[] args)
        {
            var consignees = new List<Player>();

            if (GamePlay.gpPlayer() != null)
                consignees.Add(GamePlay.gpPlayer());
            if (GamePlay.gpRemotePlayers() != null)
                consignees.AddRange(GamePlay.gpRemotePlayers());

            if (army == -1)
                GamePlay.gpLogServer(null, msg, args);
            else if (consignees.Exists(item => item.Army() == army))
                GamePlay.gpLogServer(consignees.FindAll(item => item.Army() == army).ToArray(), msg, args);
        }


        public static void ToScreen(string msg, params object[] args)
        {
            GamePlay.gpHUDLogCenter(null, msg, args);
        }


        public static void ToScreen(Player player, string msg, params object[] args)
        {
            if (player != null)
                GamePlay.gpHUDLogCenter(new[] { player }, msg, args);
        }


        public static void ToScreen(int army, string msg, params object[] args)
        {
            var consignees = new List<Player>();

            if (GamePlay.gpPlayer() != null)
                consignees.Add(GamePlay.gpPlayer());
            if (GamePlay.gpRemotePlayers() != null)
                consignees.AddRange(GamePlay.gpRemotePlayers());

            if (army == -1)
                GamePlay.gpHUDLogCenter(null, msg, args);
            else if (consignees.Exists(item => item.Army() == army))
                GamePlay.gpHUDLogCenter(consignees.FindAll(item => item.Army() == army).ToArray(), msg, args);
        }
        

        public static void ToScreenCountDown(string message, string endMessage, int seconds)
        {
            string tmpMessage = message + " ";
            int count = 0;

            while (count < seconds)
            {
                Strategy.THIS.Timeout(count++, () =>
                {
                    ToScreen(tmpMessage + seconds--.ToString(CultureInfo.InvariantCulture));
                });
            }
            Strategy.THIS.Timeout(count, () => ToScreen(endMessage));
        }


        public static void ToScreenCountDown(Player player, string message, string endMessage, int seconds)
        {
            string tmpMessage = message + " ";
            int count = 0;

            while (count < seconds)
            {
                Strategy.THIS.Timeout(count++, () =>
                {
                    ToScreen(player, tmpMessage + seconds--.ToString(CultureInfo.InvariantCulture));
                });
            }
            Strategy.THIS.Timeout(count, () => ToScreen(player, endMessage));
        }


        public static void ToScreenCountDown(int army, string message, string endMessage, int seconds)
        {
            string tmpMessage = message + " ";
            int count = 0;

            while (count < seconds)
            {
                Strategy.THIS.Timeout(count++, () =>
                    {
                        ToScreen(army, tmpMessage + seconds--.ToString(CultureInfo.InvariantCulture));
                    });
                
            }
            Strategy.THIS.Timeout(count, () => ToScreen(army, endMessage));
        }

    }
}

In the script file i use

//$reference parts/core/COD.dll  //reference to my dll (Assembly)
using System;
using maddox.game;
using maddox.game.world;
using COD;  //My namespace

public class Mission : AMission
{

    public override void OnPlaceEnter(Player player, AiActor actor, int placeIndex)
    {
        base.OnPlaceEnter(player, actor, placeIndex);

       Message.ToChatbar(player, "Welcome {0}", player);
       
        
    }
}
