ShardUO

ShardUO is an experimental Ultima Online server emulator written in the Go programming language.

Thanks and Recognition

A huge thank you goes out to the following groups, in no particular order.

• The Penultima Online (POL) packet documentation for being a guide stone and first source of packet and GUMP information.
• Every contributor to the RunUO / PlayUO / ServUO source code for packet reference.
• Every contributor to the ClassicUO source code for packet and client behavior reference.

Nerdy Things I Might Do for Fun

• Weather patterns
• Fall damage

Miscellaneous Issues

This is a list of known issues that do not need to be resolved before the next milestone but do need to be resolved sometime.

• Reduce allocations for map query operations
• Reduce or remove golang map usage in performance-critical areas
• Proper coordinate wrapping in uo.Location.XYDistance()
• Wrapped overworld

Intentional Differences

Below are differences between how things worked in the UO:R era on live and how things work with ShardUO.

• Vendors
  • do not resell what they buy from players
  • do not use vendor economy / supply and demand mechanics
  • always stock 999 of every item every time you buy from them
  • have unlimited inventory
  • will buy anything - this may change in the future
• Mining
  • automatically keeps mining until the vein is empty

Shard Administration Advice

The ShardUO software and the creative content within were developed to host a single service called Trammel Time. Using this codebase to create a different service will require changes to configuration files, data files, and source code at minimum. To create a service with different - read standard - rules will also require extensive modification to the internal/game package, several portions of the internal/cmd/uod package, and many constant updates in the lib/uo package. To create a service that supports current Broadsword server content would require nearly a complete re-write.

This repository is licensed under the AGPLv3 or later (see LICENSE). This license requires that any modification to this source code be made available to the public under the same license terms. This requirement to share the source code goes into effect when the software is made available for network connections regardless if a binary was distributed or not. I chose this license because I want to share knowledge and appreciation of the Ultima Online service during the late 1990's and early 2000's. I welcome anyone who would use this repository or its associated services who share that appreciation.

That said below are some things I have learned about administrating this shard.

Deployment

• Deploy onto a Debian-based system using systemd.
  • Create a user sharduo and do the rest of these sub-steps as that user.
  • Copy the directory TrammelTime from the client deployment archive and unzip.
  • Clone the git repo somewhere else in your home directory and go build ./cmd/uod .
  • Copy ./uod to ~/TrammelTime/
• Copy the file ./deployment/uod.service to /etc/systemd/system .
• Reload the services or restart the server, the service will now start on boot.
• On first run the service creates default configuration files that need to be edited and will then panic.
• Now lock down your firewalls and routing rules. The only ports you need open are 7775 and 7777 (don't forget your ssh port :D ).

Gameplay Behavior

• It takes about a minute after first shard start for all of the ore to spawn.
