Migrating to Unity2022.3 LTS

[zed]

I am currently working on a PR to migrate DFU to Unity 2022.3 LTS and bring game up from C#7.1 to C#11

The initial goal is to get the game up and running so that people can easily switch over from their previous saves to the new version without breaking most mods.

I have some long-term goals after this PR is merged:

• Implementing some logging behavior using Cysharp.ZLogger and slowly switching the current Debug.Logs over to it per system and allow individual mods to have their own logging context.
• Capturing and logging unhandled exceptions, etc.
• SourceGeneration to provide mods with statically typed references to localization keys.
• In general working on more modding tools.

That being said you can find my PR here to follow along with development.

You can also try out the changes locally through the standalone builds or by pulling down my branch and opening it in Unity. PRs are welcome.

If people get a chance to try this with mods (especially precompiled mods), it would help to show how feasible and easy this upgrade would be. Any users who can help out with this would be very appreciated.

I've run into a problem with Immersive Mechanisms that didn't occur in the current release 1.1.1:

Code: Select all

I'll have to see how reproducible this is, but at least we're showing signs.

I've run into a problem with Immersive Mechanisms that didn't occur in the current release 1.1.1:

I'm seeing this reported back in February on the nexus page and I am also unable to reproduce it in the editor. It happens in the standalone build though.

Whoops. Let's overlook that one then But I will request that anyone capable, try running their mods on this version! The experience so far as been extremely similar to 1.1.1 and it would be a big help.

Hi, thanks for your work, I will test it and report back. I have some 70 mods in my modlist.

EDIT: so, the only error Ive seen mentioned in the red text at the bottom is the mod UI backdrop ( https://www.nexusmods.com/daggerfallunity/mods/961 ) - it says its already loaded. And it states that, even when I disable the mod in the ingame settings.

Other thing Ive noticed is, that SOME of the interior lights are now back to default, meaning the Improved Interior Light mod has some issues. It happens only on torches. I have not investigated more. Maybe it just needs different load order, as I also use the NoMoreLEDlights mod, which affects exterior lights. It worked properly on 1.1.1 tho...

3rd thing is, that the script in DREAM which deals with the dynamic paperdoll backgrounds, seems to be not working anymore. Scipt is here, in case anyone wants to take a look:

TODBackgrounds.rar

Im not sure if other mods are affected, but I have not noticed it, during the brief test.

I still need to look into comparing lights with and without mods but I cannot reproduce your issue with UIBackdrop in editor or standalone linux64.

I'm not noticing any issues in editor or the standalone build related to lighting. The mods seem to work without errors, though NoMoreLEDs warns of possible incompatibility with other lighting mods. I'm running both in my screenshots together. ILL loaded before NoMoreLEDLights w/ all default mod settings.

At a glance everything seems fine with the above script, but my guess is that the new nullable types flag in the compiler and or the reflection is no longer valid or is potentially going to break in the near future as methods get changed to have explicit support for nullable types in their parameters and return types.

I've always thought it was pretty important to keep DFU updated to a reasonably current version of Unity. The whole purpose of DFU was to make it usable on a current OS with current hardware.

I know migrating to unity 6 would likely be a big deal

This PR mostly stems from my personal needs in order to work on DFU as the current editor version isn't playing well with my desktop environment. Editor tooling just appearing as black boxes, whole editor freezing and crashing after 10min of usage, etc.

I know migrating to unity 6 would likely be a big deal

I haven't used Unity6 yet but I know there are some big changes such as the rendering pipeline that would probably maka it less trivial to upgrade from 2019->6. If we need to in the future we can do another upgrade from 2022.3->6

New release and download link in the OP

I tested Dream 90s with the latest build.

Paperdoll backgrounds change correctly for me.

EDIT: No Problems with DREAM too
