About a month ago, I had posted an issue on the Plugin Development forums with Scoreboards. I presume it's a bug, since Aaron1011 didn't get back to me on my last post, so I thought I post it here so you guys can have a look at it.

Original Post:
Hello everyone, so I'm working on a PVP plugin, but I ran into a scoreboard problem. So in the first image was screenshotted by a contestant, C88. The problem with this image is that SalvadorZXA (me) received a team scoreboard, but was not suppose to.

The second image was screenshotted by another contestant, X, in another team. In this image though, the non contestant, SalvadorZXA is seen with a different scoreboard than image 1. Still though, SalvadorZXA was not suppose to receive the scoreboard under it's username.

Through SalvadorZXA's perspective though, neither of the contestants can be seen with their team names under their usernames.

Does anyone have any clue to how this is happening and know of a way to fix this? Thanks.

Code that sets up the scoreboards:

Note: This method is called twice. Once to set up one team, and one to set up the other.

public static void setUpTDMT(List<Player> teamContestants, Text teamName) {
	
    for (Player player : teamContestants) {

        Scoreboard scoreboard = Scoreboard.builder().build();
        
        Objective teamTagNameObjective = Objective.builder().name(teamName.toPlain()).displayName(Text.of(teamName)).criterion(Criteria.DUMMY).build();
        
        scoreboard.addObjective(teamTagNameObjective);
        
        scoreboard.updateDisplaySlot(teamTagNameObjective, DisplaySlots.BELOW_NAME);
        
        player.setScoreboard(scoreboard);
    }
}

Bumping up report.

@SjsolisZXA By "team scoreboard", do you mean the extra like of text for the score? If so, that's intended behavior in vanilla; each player can see one and only one objective under other player's names, and that objective is shown for all players they see, and Sponge can't work around that.

[SjsolisZXA]

That would make sense except that I have code that can retrieve another player's "team scoreboard" and read it correctly. The only issue is that it's displayed incorrectly from a contestant's point of view.

What I'm trying to say is, BELOW_NAME for X's scoreboard is not what other players see below X's name. It's what X sees under other players' names. This is intended behavior.

To add to this, not only is it intended behaviour, but unfixable given the current Minecraft codebase.

[ryantheleach]

To my knowledge this is intended behavior and unfix-able without client changes. If someone can provide evidence to the contrary feel free to reopen.
