What's even that?

electronicboy · 2018-12-15T15:18:03Z

Team §7§0§l[§9§lP_Mc� already exists in this scoreboard

Known bungeecord issue, you can't swap to servers which duplicate scoreboard names, "fix" is to ensure that servers won't duplicate scoreboard team names, hopefully I'll try and take a proper stab at this sometime...

Malachiel87 · 2019-08-26T22:11:38Z

any progress on this?

Legendbender · 2019-08-26T23:09:42Z

Workaround already presented in here.

JHarris12345 · 2019-10-30T15:03:39Z

I dont understand the scoreboard fix or how I got about fixing it. I dont use default scoreboard

Janmm14 · 2019-10-30T23:22:52Z

you need your plugins to use different scoreboard names on each server

JHarris12345 · 2019-11-02T03:24:47Z

How do I do this @Janmm14. Also which plugins?

electronicboy · 2019-11-02T03:27:26Z

whichever plugin is creating the team that is conflicting on the other server, if you copied worlds over and aren't using plugins, potentially wanna consider delating the scoreboard.dat for the servers involved;

The only current fix is for bukkit plugins to take steps to prevent team name collisions across servers, this is an upstream issue

JHarris12345 · 2019-11-03T13:32:12Z

Hmm I use featherboard and TAB. Not sure how to go about fixing

JHarris12345 · 2019-11-03T16:31:28Z

@electronicboy How do I prevent plugins from creating the same team names on my different servers?

electronicboy · 2019-11-03T18:22:07Z

Once again, you would need to speak to plug-in authors to try to mitigate this;

If this is your suggested fix for the proxy, it would require additional overheads to remap teams, would also create some potential oddball handling if bungee plugins come into play The ultimate fix is going to be to figure how to handle the server switch better, my current thought is to just queue scoreboard packets and flush them through, it is it's own set of headaches and mess, but the only other alternative is to leave this solely on server/plug-in devs

@electronicboy would intercepting the inbound Scoreboard Send work? Compare the previous scoreboard name with the latter and if they match; mutate the name by a character or so and send that packet instead? If I'm correct team/scoreboard packets don't require a scoreboard name they just latch on to the clients current scoreboard and if the client thinks it has a new scoreboard now; the team in theory won't pre exist? Would obviously need to confirm it wasn't the same server sending the Send Scoreboard packet though

electronicboy · 2019-11-05T12:17:45Z

The client only has a singular scoreboard, teams are shared across all instances; This issue is also not down to the client, this is pretty much 100% a flaw in bungees server connection process; The new target server sends it’s scoreboard data before the proxy has cleaned up the scoreboard on the client, rewriting team names just adds additional complexity, bloat and overheads in the proxy as an afterthought, this would also break the clients tab completion for scoreboards in these cases

Mystiflow · 2019-11-05T14:12:04Z

I haven't looked into the client code but what purpose then does the name string serve in the Scoreboard Send packet?

queue scoreboard packets and flush
them through

Do you mean storing each server sent scoreboard packet in a list and then sending the destroy packet for them on server switch?

@JH3Y50N Your issue is completley different (unrelated to duplicate scores!) . FYI bungee has recently fixed a regression with <1.13 scoreboard/team stuff, so wait for waterfall to update.
