CentrED
CentrED stands for Centralized Editing. It is a Client/Server based map editor for Ultima™ Online.
The intention behind this is, that the only available GodClient is rather old and was never really supported by any server emulator (at least not that I know), but I wanted the ability for several people to work on the terrain and statics together, without having to constantly transfer their current state.
Features#
- Complete serverside map. All blocks are transfered on request.
- Modify Terrain
- Add, delete, move and hue Statics
- Change the altitude of Terrain and Statics
- Account management with four accesslevels (None, Viewer, Normal and Administrator)
- Restrict clients write access to specified regions (some sort of group management)
- Integrated Chat
- Client list with ability to jump to other clients position
- Virtual Layer to ease working on roofs or in black areas
- Large scale editing (move/copy, delete, draw, insert whole areas of the map)
- Easily jump to locations stored in a list or via the radar view of the whole map
- Ability to undo the last set of changes
- Preview changes before actually performing them
- Renders the map similar to the UO Client
- Shows animated tiles
- Show different light level and display light sources
- Support as many different Statics as the TileData file can hold
- Server and Client for 32bit Windows and Linux

Server Setup#
CentrED uses a client-server architecture. The server is a command-line application.
Requirements: i386 Windows or Linux (runs on 64-bit too), minimum 100MB RAM, an open TCP port.
Configuration: The server looks for a config file matching its name with .ini extension (typically cedserver.ini). On Windows, it auto-prompts on first run. On Linux, launch with --init parameter. Default port: 2597.
Important: Map files load with exclusive read/write permissions — no simultaneous access by other programs. RadarCol.mul and Tiledata.mul load as read-only.
Map File Reference#
| Map | Dimensions | File | Size |
|---|---|---|---|
| Felucca (pre-ML) | 768x512 | map0.mul | 77 MB |
| Felucca (ML) | 896x512 | map0.mul | 89 MB |
| Trammel (ML) | 896x512 | map1.mul | 89 MB |
| Ilshenar | 288x200 | map2.mul | 11 MB |
| Malas | 320x256 | map3.mul | 16 MB |
| Tokuno | 181x181 | map4.mul | 6 MB |
Each map consists of three files: mapX.mul, staidxX.mul, staticsX.mul.
NoDraw Tiles#
CentrED can hide certain tiles via a nodraw.txt config file. Format:
T$2— hide terrain tile 2S$2198-$21A4— hide static tiles in range 0x2198 to 0x21A4
Uses hexadecimal notation prefixed with $. The client loads from the application directory, user config directory, and MUL data directory.
