Code:

using System;
using Server;
using Server.Gumps;
using Server.Network;

namespace Server.Items
{
public class WorldTableChestAddon : BaseAddonContainer
{
public override int DefaultGumpID{ get{ return 0x49; } }
public override int DefaultDropSound{ get{ return 0x42; } }

[Constructable]
public WorldTableChestAddon( bool east ) : base( east ? 0x4BF9 : 0x4BFF )
{
if ( east ) // East
{
AddComponent( new AddonContainerComponent( 0x4BF9 ), 0, -1, 0 );
AddComponent( new AddonContainerComponent( 0x4BF8 ), 1, -1, 0 );
AddComponent( new AddonContainerComponent( 0x4BFA ), 0, 0, 0 );
AddComponent( new AddonContainerComponent( 0x4BF7 ), 1, 0, 0 );
AddComponent( new AddonContainerComponent( 0x4BFB ), 0, 1, 0 );
AddComponent( new AddonContainerComponent( 0x4BF6 ), 1, 1, 0 );
Name = "World Table Chest";
Weight = 5.0;
}
else // South
{
AddComponent( new AddonContainerComponent( 0x4BFF ), -1, 0, 0 );
AddComponent( new AddonContainerComponent( 0x4BFD ), -1, 1, 0 );
AddComponent( new AddonContainerComponent( 0x4C00 ), 0, 0, 0 );

AddComponent( new AddonContainerComponent( 0x4BFE ), 1, 1, 0 );
Name = "World Table Chest";
Weight = 5.0;
}
}

public WorldTableChestAddon( Serial serial ) : base( serial )
{
}

public override void Serialize( GenericWriter writer )
{
base.Serialize( writer );

writer.Write( (int) 0 ); // version
}

public override void Deserialize( GenericReader reader )
{
base.Deserialize( reader );

int version = reader.ReadInt();
}
}
