        };
        menuItems.Add(back);

        Menu = new GTA.Menu("Players", menuItems.ToArray());
        //Interface
        Menu.HeaderFont = Font.HouseScript;
        Menu.HeaderColor = System.Drawing.Color.MediumBlue;
        Menu.HeaderCentered = false;
        Menu.HeaderHeight = 35;
        Menu.HeaderTextColor = System.Drawing.Color.White;
        Menu.HeaderTextScale = 0.7F;
        Menu.ItemHeight = 33;

        View.MenuPosition = new System.Drawing.Point(1000, 100);

        this.View.AddMenu(Menu);

List<Player> GetPlayers()
    {
        List<Player> players = new List<Player>();
        List<Ped> peds = new List<Ped>();
        foreach (Ped i in GTA.World.GetAllPeds())
        {
            peds.Add(i);
        }

        foreach (Ped i in peds)
        {
            if (i.IsPlayer)
            {
                players.Add(GTA.Native.Function.Call<Player>(GTA.Native.Hash.GET_PLAYER_PED, i));
            }
        }
