1.20.2 Support #1088

Paul19988 · 2023-09-24T14:14:20Z

Adds support for 1.20.2 clients.
Only caveat at the moment is events that run before the player has reached the play state may need to be queued in future.

Joo200

Looks nice overall. However it could be nice if you reduce the reformatting of this PR to minify the diff.

There are a lot of unnecessary code style changes

Paul19988 · 2023-09-24T21:31:09Z

Some of the reformats are from the IDE attempting to change it to what it believes to be right & not manual intervention

astei

Please reformat these changes to use the Velocity code style (~Google code style). Left a few other comments.

Is there a pre-compiled binary available for testing?

Attack8 · 2023-09-25T15:36:17Z

Is there a pre-compiled binary available for testing?

You should compile it yourself since there is no official build
I could give you a comiled jar, but you shouldn't trust unofficial builds

Tried out this PR and experiencing this error on join:

I’m not sure how to reproduce it but for some reason only happens randomly if you disconnect and try to reconnect, if you get this error connecting you will keep getting this error until you restart the Minecraft client. Hope this information helps.

Beginning it works. After a timeout, the error occurs.

Looks like you have a plugin on the proxy attempting to send the player a message before they've finished the configuration stage

totKing · 2023-10-03T14:53:28Z

https://mclo.gs/EI1AL4a Mit dem letzten Push ( 1b07659 )
Von Anfang an klappt es. Nach einer Zeitüberschreitung tritt der Fehler auf.

Es sieht so aus, als ob Sie ein Plugin auf dem Proxy haben, das versucht, dem Player eine Nachricht zu senden, bevor er die Konfigurationsphase abgeschlossen hat

It worked yes, after last commit from you.
If the player gets timeout, he can not enter until the proxy restart.

MVanilla · 2023-10-03T19:17:38Z

If the player moves to a different backend server during the configuration phase, an error will occur. Velocity logs
[22:43:53 INFO]: [connected player] MyName (/127.0.0.1:49436) has connected

Plugins used: https://github.com/Elytrium/VelocityTools

Solution: When a player is in the configuration phase, Velocity should either deny the player from moving to another backend server or use a queue.

Are you planning on fixing this? This error occurs when using the server send or join queue plugin.

yinzixie · 2023-10-06T02:28:37Z

Any progress ?

p0t4t0sandwich · 2023-10-06T05:53:07Z

Just need to be patient, if you really need it now and can't live without it, follow the readme on how to compile it.
Asking if there's any progress won't make it go faster.

Strahilchu · 2023-10-06T12:44:41Z

Come on Velocity you can do this

Phoenix616 · 2023-10-06T14:25:10Z

Please stop spamming this issue if you have nothing to improve it or feedback from your testing. If you just want updates on the progress then follow the issue/specify what notifications you want on the right, if you want to show your support then react to the posts, and if you want to test the 1.20.2 integration then build the PR (seeing as it uses gradle's wrapper it should be extremely easy to build it)

On an actual relevant note: Has the resource pack API issue been addressed/discussed @Paul19988? (See #1088 (comment)) Because I don't see anything about that in the PR. (But it's extremely hard to review with all the formatting changes :S)

DeprecatedLuke · 2023-10-07T06:30:36Z

If you run ViaVersion on the backend servers make sure you upgrade it to 4.8.1 before use if you attempt to use this branch.

Stuff working:

Previous versions
Geyser

Possible issues:

Boss bar does not get cleared when switching servers?
Slow connections have trouble switching servers ( on 1.20.2? ). No errors in console except for the normal timeout messages.
Plugin compatibility. Network I oversee only uses 1 custom-made plugin (managing backend servers, kick and send handling as well as motd) alongside Geyser.

There is no error spam and is quite usable in production.

Gerrygames · 2023-10-07T13:24:47Z

I implemented support for the backend server switching back to config state.

I also implemented a fix for the issue with the resource pack being cleared on server switch. The previously applied resource pack just gets reapplied after the server switch is done.
For some users it might be useful for the resource pack to be cleared on server switch. So we might need to find a better solution for this. However I would like to make sure we don't break the API. So this approach is the best solution for now. Also we don't know if Mojang will fix this issue with 1.20.3.
