Bug description

When teleporting (has tested /warp and /home) between dimensions (has tested Overworld and end), /fly gets toggled off in survival mode. This appears unrelated to the config option "world-change-fly-reset:" as using an end portal does not reproduce the issue. Player testing issue has both essentials.fly and essentials.fly.safelogin as permissions. Plugins being used are EssentialsX (including Base, Spawn, and Chat), Vault, and LuckPerms.

Steps to reproduce

1. Ensure world-change-fly-reset is false in the config
2. Have EssentialsX, EssentialsX Spawn, EssentialsX Chat, Vault (version 1.7.3-b131), and LuckPerms (version 5.3.47) installed.
3. Set a home in the Overworld and a warp in the end.
4. Have essentials.fly and essentials.fly.safelogin as permissions
5. In the Overworld switch to Survival and toggle /fly on. Go to the warp in the End, double tap your jump key and attempt to fly. (Note: This happens when teleporting in either direction.)

Expected behaviour

Based on configuration settings and permissions, /fly should remain enabled when teleporting betweens dimensions.

Actual behaviour

/fly does not remain toggled on when teleporting between dimensions.

[lucky819-dev]

i have the exact same problem

[triagonal]

This isn't an Essentials issue. I was able to reproduce the issue using a test plugin that teleported the user between dimensions and observed the same behaviour as described here without any other plugins installed. This might be an issue with the Bukkit API itself, further investigation is required.

[Nibby49]

I am not skilled enough with java to write tests for this issue. However, please let me know if you need any more information or if I can be of any assistance. Otherwise, good luck @triagonal and the rest of the essentialsx team!

[ghost]

Same issue for me,

Were using PaperMC Build 99 (Latest when issue started)
Essentials 2.19.0-dev+221

Permissions are set up right and config is right no errors or so.

[TNTUP]

Can confirm.

EssentialsX 2.19.0-dev+221-1556b91
Paper Build#109

[remdui]

Can confirm, the config option does not work. Fly is always disabled, even for players with wildcard permissions.

[JRoy]

After further investigation, this occurs on vanilla single player as well (1.17.1). If this didn't occur on 1.16.5, this should probably be reported to Mojang but I didn't get a chance to test that yet.

[Nibby49]

I can confirm that this did not happen prior to 1.17 (aka 1.16.5 and down). If you would be so kind, please provide me with evidence to back up any possible bug report I am to make to Mojang. Thanks in advance!

[remdui]

With essentials 2.18 this problem does not occur on 1.17.1.
The problem started when we upgraded to 2.19 dev builds.

[MacTh3Mac]

have recreated this issue on a server with no essentials on it. Not an essentials issue.

[Nibby49]

I have very limited knowledge of java, and I apologize if what I am about to suggest seems naive or uninformed, but could this issue be caused by using a specific type of code to simulate flying? I'm not sure how to further elaborate on that, but perhaps essentials updated the flying code in the development builds of 1.19.0? Apologizes again if that doesn't make sense, I'm just suggesting a theory. Regardless of the above, I would imagine it may be an issue with paper or upstream spigot seeing as other plugins are effected too.

I wish you all luck in finding a solution to this, and please let me know if you have any questions or if I can be of any assistance.

[pop4959]

@Nibby49 Essentials uses the Bukkit API to set flight abilities on the player. So yes, this is something that if anything needs to be fixed upstream. JRoy already mentioned that he was able to get this issue to occur in Vanilla. If the code being used by Bukkit isn't correct for 1.17 it will need to be updated. Otherwise, it's probably just an oversight on Mojang's end. Either way, nothing that Essentials would be directly able to fix.

[Chew]

As stated this is a known, easily reproducible upstream issue, and still nothing we can fix here.

[electronicboy]

    @EventHandler(priority = EventPriority.HIGH, ignoreCancelled = true)
    public void onPlayerTeleport(final PlayerTeleportEvent event)
    {
        if (event.getFrom().getWorld() != event.getTo().getWorld()) {
            if (event.getPlayer().isFlying()) {
                worldTeleports.put(event.getPlayer().getUniqueId(), Bukkit.getCurrentTick());
            }
        }

    private final Map<UUID, Integer> worldTeleports = new HashMap<>();
    @EventHandler
    public void onPlayerChangeWorld(PlayerChangedWorldEvent e) {
        final Integer ifPresent = worldTeleports.remove(e.getPlayer().getUniqueId());
        if (ifPresent != null && Bukkit.getCurrentTick() == ifPresent) {
            e.getPlayer().setAllowFlight(true);
            e.getPlayer().setFlying(true);
        }

    }

Working off an old fork of the codebase here and not exactly fond of this, but, it works™ (Can easily be thrown into a standalone plugin)

This OFC is likely nuanced and not really sure it should belong in Ess but is the best "2 second" workaround I can come up with, the issue here is that mojang added a call to set the players gamemode inside of ServerPlayer#restoreFrom which sets the expected abilities for the players gamemode

edit: in testing locally this worked, in prod, it's apparently missing some stuff... trying to look at a delay to see if that helps, but, I don't see how this could fail unless there is a missing step somewhere... sigh

Persists on 1.18 and 1.18.1 sadly :(

[donvdp]

this problem is still here. running the lastest version paper-1.18.1-214 in combination with latest EssentialsX dev version EssentialsX-2.19.3-dev+27-bc2da98

I have chatted in discord with electroniccat on the paper discord, and he tells me he tried to help essentials fix the problem with a github gist. He has update his code a bit. but its still the basic concept from his post above here.

[HexedHero]

Any news on this?

[Leahcimkrob]

I have the same issue with Essentials 2.20.0-dev+6-ea5cdc0

[bigsmileling]

Any update?

[Aoredon]

Still having issues with this

[JRoy]

My comment here still applies. This is a vanilla issue and I'm not sure a workaround should be part of Essentials itself.

[mdcfe]

(apparently I never posted my thoughts on this issue in public, so here goes:)

Yes, this was a vanilla change. However, the change here breaks behaviour that is implied by EssentialsX's own config options. I would prefer we implemented a new option that lets people restore pre-1.17 behaviour if they choose (in turn restoring the functionality of our existing config option).

[TNTUP]

Someone developed a plugin that fixes EssentialsX's fly on world change so this issue does not affect me anymore, not sure if im allowed to say that here since it would be offtopic (Sorry!)

It's not off-topic, but we would like to implement a solution within EssentialsX itself rather than relying on a third party plugin (since right now, the fly on world change options are useless above 1.17).

[Leahcimkrob]

Top Idea.

Interesting! Maybe you can share this plugin, I would be interested to add it because I guess there is no other good alternative :)
