ClassicUO: An open source Ultima Online Classic Client

​

For over two years now, a open source Ultima Online client has been under development by Andrea Karasho and a very small team of developers with the aim of making a viable alternative to the standard OSI and the other open-sourced unfinished UO clients (like Orion and Sallos).

Early in 2019, I started working with the developers to integrate Razor into ClassicUO while at the same time testing the client on UO:R and either reporting bugs or submitting code changes directly to fix issues related to client 5.0.8.3 and UO:R.

To use ClassicUO on UOR, it's recommended that you use the UO:R Launcher. Check out the guide and download link below.

DISCLAIMER (PLEASE READ):

• While this client is considered stable, it's still in the BETA phase. By the definition, it means you're testing software and you may have issues from something minor you can live all the way to a potential crash.

INSTALLING/UPDATING:

Guide:

http://www.uorenaissance.com/downloads/launcher/guide/

Download via the UO:R Launcher here:

https://www.uorforum.com/threads/uo-renaissance-launcher.45587/

COMMON ERROR:

The launcher should take care of this, but just in case if your crash log looks like this:

Code:

System.DllNotFoundException: Unable to load DLL 'zlib': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Head over to https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads and download the x64 install. After you install that, try ClassicUO again.

UOAM:

UOAM will only work if it detects the standard OSI client running, which enabled the UOAssist API support of the app. To use UOAM with ClassicUO, do the following:

1) Open the standard OSI client (with or without Razor) and leave it minimized. You don't have to log in.
2) Open ClassicUO with Razor
3) And finally open UOAM (Locked), and as long as you leave the standard OSI client open, it will track in ClassicUO perfectly.

Thanks to @Miatrio for finding this work around. I know losing the use of UOAM to use this new client was a big change for many.

EDIT 10/17/2020:
Removed old Powershell related install steps, use launcher.
Removed warnings about grid-loot and open corpses as this was not an official shard stance.
Removed dated "getting started video"
Updated intro to reflect the current state of ClassicUO

Omg. I’m in love. Installing tomorrow.

Xoxo

I'm just glad to have the opportunity to contribute my small part to the project -- the real wizards are KaRaShO, zolter and Sascha.

Here's me running around back in Oct 2018 trying to sort out some login issues (pre-Razor integration). The progress has been really amazing between what you see in this video and what you get now.

​

wow this is great
being able to zoom out is a game changer for me
thanks for the hard work!

does this mean i can see a pk from very far away if i zoom out?

Awesome! Thanks for the guide quick and your efforts to put Razor working on this great thing.

Regardless of what client you use, you can only see people and items 18 tiles away. Zooming out doesn't increase that as it's managed by the server (notice when I'm zoomed out doors and signs were missing since they are out of range).

That said, the older client doesn't let you see 18 tiles due to the limited window resolution while this one does. So yeah, you'll potentially see them a bit sooner depending on the direction they're coming in on.

thanks for the clarification.
that's fine as it would have been a bit unfair to pks.
i have a very small screen that's why i am currently seeing fewer tiles than i should.
being able to zoom out solves this problem.

Install went very smooth. I can now play UO on my 34 inch gaming monitor. I can stretch it to the entire thing and zoom in because I sit kind of far away and stuff is really small at the resolution of my monitor.

This is amazing. I may actually become active again!

What about ships? Asking for a friend

Yep, any item, multi (houses, boats), mobile that come into your client are being sent when you're 18 or less tiles away. If you watch my video, you see me running around Ocllo dungeon, and since that dungeon is built in game vs. on the static map, you can see the the borders appearing/disappearing as I run they can enter/exit my 18 tile range.

Looks promising. A client capable of higher resolutions and frame rates would go a long way towards "smoothing" things out and polishing this game if the server side were ever upgraded, also. Reminds me of the kind of detail possible with the artwork from a website a long time ago...High Res Challenge...

http://www.andrea.net/uo/general/art/hrc_dragon.shtml

I always liked this high res challenge as it stayed with the look and feel of UO while giving the graphics junkies a bit more.

more of a general concern...
I see that the powershell (everytime you open CUO) checks for "updates".
1: does this mean it keeps itself up to date to the "latest" version
2: does it update Razor auto?
3: can this all be enabled & disabled? (I rather not update automatically)
4: if it does auto update, can it be rolled back to a previous version?
5: are release notes provided for each update?

If this is my only way to make music play UO on Mac OS, then I will try the installation.

Hey @Labeler do you install under mac? or like most ... I think you're one of the mac users

i havent achieved CUO in wineskin yet (under high sierra)
i hope to focus on this starting mid september to nail this down.

also want to try port this over to OSX mojave using the new file system format (i lost the name)


momentarily i can only explore CUO using bootcamp. this obviously defeats all the purposes of having a mac, so hope i can move back to OSX in the long run.

quick did mention he doubts Razor and CUO will ever work natively on Mac (wineskin or MONO for that matter)
which means the end of UO on mac. cause who can play without razor... its like being handcuffed, head under water and just a straw to breath some air... nowadays.


one can only have hopes right...

Installed last night and dont think I could ever take that step back. Caught me off guard at first with how smooth it ran and almost didnt feel right. But as I played more and discovered more things about the client, I'm a fan of it. Thanks @Quick . Windows 10 installation was painless with your video guide.

Saw the options for counters in the client, is there a way to have them in title bar with the icons? I'm sure I'll get use to client counters but figured I'd ask.

1. Yes, if you run this script on the same folder with everything installed, it will update CUO and Razor to the latest developer version.

CUO itself also has an auto-update feature when you launch it normally.

2. Yes, the PowerShell script will update both. Also anyone can manually download Razor and extract it over the existing install if you wanted to do it manually.

3. CUO updating upon launch can't be disabled at the moment, but I plan on submitting a code change to have a way to disable it.

4. Yes, manually though by downloading the previous build artifacts and extracting over the existing install.

5. On major releases yes, you can find them on the GitHub releases page. But for day to day updates on the dev version, you'd need to look at the commit notes. The version this PowerShell script downloads is the latest developer preview, which builds every time a code change is submitted to GitHub.

ClassicUO can run in Windows, Linux and Mac naively. With Windows and Linux, Razor also works fine. With Mac, well here's a copy/paste with some info explaining the problem:

Here's discussion on the mono github repo
https://github.com/mono/mono/issues/6701

Great, glad you didn't have any issues. I agree, this client does make it hard to go back to the OSI client simply because of the FPS boost alone.

Unfortunately we weren't able to put those icons in the titlebar like you get on the standard OSI client (SDL2 doesn't support that) so that counterbar gump feature was added as an alternative. You can still display values up there, but the associated images and colors will not display.
