How to Configure Chaos Castle on MU Online Server

Introduction

Chaos Castle is one of the most popular MU Online events, placing players on a shrinking platform until only one survivor remains. Configuring it correctly requires adjustments to configuration files, database tables, and EventServer parameters. This guide covers the complete setup for Season 6 Episode 3 servers running MuServer with SQL Server.

Prerequisites

• SQL Server 2008 or later with the MuOnline database configured
• GameServer, ConnectServer, and EventServer installed and functional
• Administrator access to the Windows server
• SQL Server Management Studio (SSMS)

Step 1: Verify the File Structure

Before any configuration, confirm that the event files exist in the correct directories.

GameServer/
  Data/
    Events/
      ChaosCastle/
        ChaosCastle.txt
        ChaosCastleReward.txt
        ChaosCastle_ItemList.txt
EventServer/
  Data/
    ChaosCastle/
      IGS_ChaosCastle.txt

If ChaosCastle.txt or ChaosCastleReward.txt are missing, copy them from the server installation package before continuing.

Step 2: Configure ChaosCastle.txt

Open GameServer/Data/Events/ChaosCastle/ChaosCastle.txt in a text editor (Notepad++ is recommended to avoid encoding issues).

; Chaos Castle Configuration
; Format: Level, MinLevel, MaxLevel, MaxUserCount, StayTime, PlayTime, MapNumber

1  15  49  80   3  15  29
2  50  99  100  3  15  29
3  100 149 100  3  15  29
4  150 199 100  3  15  29
5  200 249 100  3  15  29
6  250 299 100  3  15  29
7  300 400 200  3  15  29

Field reference:

• Level: Chaos Castle tier (1 to 7)
• MinLevel/MaxLevel: Character level range allowed to participate
• MaxUserCount: Simultaneous player cap per instance
• StayTime: Waiting-room hold time in minutes before the event starts
• PlayTime: Event duration in minutes
• MapNumber: Map ID (29 = Chaos Castle)

Step 3: Configure Rewards

Edit GameServer/Data/Events/ChaosCastle/ChaosCastleReward.txt:

; Format: CCLevel, ItemCode, ItemIndex, ItemLevel, ItemDurability, ExcellentOption, Zen
1  13  8   5  255  0  5000000
2  13  8   6  255  0  7000000
3  13  36  6  255  0  8000000
4  13  36  7  255  0  9000000
5  13  37  7  255  0  10000000
6  13  37  8  255  0  12000000
7  13  37  9  255  0  15000000

Step 4: Schedule the Event in the Database

Open SSMS and connect to the MuOnline database. Run the script below to set Chaos Castle schedules (Event_Code = 8):

-- Remove old Chaos Castle schedule entries
DELETE FROM IGS_Event_TimeTable WHERE Event_Code = 8;

-- Insert new schedules (example: every 2 hours)
INSERT INTO IGS_Event_TimeTable (Event_Code, StartHour, StartMinute, IsActive)
VALUES
  (8, 0,  0,  1),
  (8, 2,  0,  1),
  (8, 4,  0,  1),
  (8, 6,  0,  1),
  (8, 8,  0,  1),
  (8, 10, 0,  1),
  (8, 12, 0,  1),
  (8, 14, 0,  1),
  (8, 16, 0,  1),
  (8, 18, 0,  1),
  (8, 20, 0,  1),
  (8, 22, 0,  1);

Step 5: Enable the Event in the Control Table

Check and activate Chaos Castle in the event control table:

-- Check current state
SELECT * FROM IGS_ChaosCastle_Info;

-- Enable the event
UPDATE IGS_ChaosCastle_Info
SET Operate = 1,
    MinUserCount = 2,
    MaxPlayTime = 15,
    WaitingTime = 3
WHERE Event_Code = 8;

If the table IGS_ChaosCastle_Info does not exist, use:

-- Enable via generic event table (older builds)
UPDATE IGS_EventInfo
SET Operate = 1
WHERE Event_Code = 8;

Step 6: Configure the EventServer

Open EventServer/EventServer.ini and locate the Chaos Castle section:

[ChaosCastle]
Enable=1
ServerCode=0
GameServerIP=127.0.0.1
GameServerPort=55557
MinPlayerToStart=2
MaxWaitTime=180
EventDuration=900

Key parameters:

• Enable: 1 to activate, 0 to disable
• MinPlayerToStart: Minimum players required to start the event (recommended: 2 for smaller servers)
• EventDuration: Duration in seconds (900 = 15 minutes)
• GameServerPort: Internal communication port between EventServer and GameServer

Step 7: Configure GameServer.ini

Open GameServer/GameServer.ini and confirm the Chaos Castle-related parameters:

[EventServer]
Enable=1
EventServerIP=127.0.0.1
EventServerPort=55557

[ChaosCastle]
Enable=1
MapNumber=29

Step 8: Test the Event

Follow this sequence to test without waiting for a scheduled time:

1. Restart the EventServer
2. Restart the GameServer
3. Connect to the server with a GM account
4. Type in chat: /chaoscastle 1 (or the equivalent command for your build)
5. Join with at least one additional character to meet MinPlayerToStart

Troubleshooting

Event does not open on schedule

1. Confirm IGS_Event_TimeTable has rows with Event_Code = 8 and IsActive = 1
2. Verify the EventServer is running: tasklist | findstr EventServer
3. Review EventServer/Log/EventServer_YYYYMMDD.log for connection errors

Players cannot enter

-- Check the configured level range
SELECT * FROM IGS_ChaosCastle_Info;

-- Confirm the map is enabled
SELECT * FROM IGS_MapInfo WHERE MapNumber = 29;

GameServer crashes when delivering rewards

Verify that all items in ChaosCastleReward.txt exist on the client side. Items with ItemLevel higher than the maximum allowed (typically 15) cause a crash on reward delivery:

-- Recent error log entries
SELECT TOP 50 * FROM T_Log_Error
ORDER BY LogDate DESC;

Final Notes

With all steps completed, Chaos Castle will run automatically on schedule. Monitor the first few event cycles by watching the logs under EventServer/Log/ and GameServer/Log/ to ensure stable communication between services. Adjust MinUserCount upward as your server population grows.
