Help?

Question, I'm trying to set TP permissions to a group so I can allow players to TP to waypoints with Xaero's Minimap. I've tried adding minecraft.command.tp which Xaero uses to TP but no success. any help?

# glossy mesa Help?

The error message says it all.

First of all, check your server Logfile. You can fix the error with the error messages that are in the Logfile.

I am having issues with "Styled Chat" and Luckperms to work. I have the chat mod installed and got the PlaceholderAPI in place. This is on fabric, but the chat does not want to change. I did the works in the config file but get no dice.

Anyone got something?

is there a way to check if player has permission set to true ? (ignoring the * permission) ?
i've tried that:

public boolean hasPermission(Player player , String permission) {
    return player.isPermissionSet(permission) 
    && player.hasPermission(permission);
}

and it does not work, also i've tried using LuckPermsAPI, but to no avail

public Tristate hasPermission(String permission) {
    return toLuckPermUser().getCachedData()
            .getPermissionData()
            .checkPermission(permission);
}

it returns TRUE instead of UNDEFINED, Tristate has: [TRUE,FALSE,UNDEFINED] ..
ping me if you have an idea

fast delta
#

CachedPermissionData#checkPermission(String) is the exact same kind of check performed by Player#hasPermission(String); the isPermissionSet check should work, if you do not have the permission set (neither true or false), it will return false, short-circuit the hasPermission check and return false; if you have the permission explicitly set to false, that will override the global wildcard *, otherwise if you have it set to true it will return true

#

could you share the output of /lp user <the user> permission check <the permission> ?

#

Hey! I'm trying to check if an offline bukkit player has a permission, using code below. Unfortunately it returns a different value than Player#hasPermission, because it doesn't take player's op status into account. Is there a way to get the same result as using bukkit api?

if (luckpermsUser == null) return true;

return luckpermsUser.getCachedData().getPermissionData().checkPermission("something").asBoolean();```

*using join() because it's executed asynchronously*
fast delta
#

not really

#

such things only work when the live player is online

#

I wanna say "like contexts" but you can query permissions with your own defined context set, op works slightly different

white osprey
#

So I'll have to see how does the underlaying mechanic work on online player and try to reproduce it somehow using offlineplayer's op status?

#

I guess it checks for registered plugin permissions

fast delta
#

i mean, if the player is op it'll just return true, that's how that works lol

#

although the op processing can be disabled

wild whale
#

Yeah the root problem you're hitting is the OP calculator isn't active for offline players because LP doesn't check the platform's OP status - heck, I don't even know if you can query whether an offline player is opped or not easily

tardy quail
#

Oh dam, i bet its a race condition

because they all end up in the default group if it doesn;t work

I want to retrieve the prefix of a group

tardy quail
#

Just to confirm, user.data().clear(NodeType.INHERITANCE::matches); only removed groups that are inherited from the new group to be added?

#

So if they have a paid rank completely seperate, that isn't inherited from the group being added, it wont be removed

How can I retrieve the prefix of a group?
I'm using the docs and I understand that it is something to do with Nodes.
https://javadoc.io/static/net.luckperms/api/5.4/net/luckperms/api/node/types/PrefixNode.html

Right now I've reached this far:

import:
    net.luckperms.api.LuckPerms
    net.luckperms.api.node

set {_group} to (instance of the plugin "LuckPerms").getServer().getServicesManager().load(LuckPerms.class)```
PrefixNode (LuckPerms API (v5.4))

declaration: package: net.luckperms.api.node.types, interface: PrefixNode

Hi, i am trying to implement luckperms api to my forge project, the main thing i want to achieve is to check if player has certain time of playtime and if so then i want to add him to luckperms group. the playtime thing is basic i can do that but for that group i need to use api (well no shit, what else could i use? KEKW). So... i read documentation, did what i was told to do but i can't get it to work in my forgemdk project. Am i missing something or it's just no possible? If so what should i use to achieve my goal?

#

I have it in external libraries but i am not sure if it's working. shouldn't it be loaded as mod when i start task runServer, as any other dependencies and APIs would?

main dagger
finite leaf
#

Yeah i did that, but i don't know if i'm just plain stupid or it's not supposed to show up as mod when i start server in forgemdk, if so... how do i test it?

main dagger
#

you need to have the LP forge jar in your mods folder

#

but only on the server

#

it will not work on a client

finite leaf
#

oh, so that's what i'm missing... 😅 anyway sorry for being stupid and thanks for help

# main dagger it removes *all* inheritance nodes from that player

Hm, I obviously misunderstand that method then

Is there any decent way of remove any groups that are children of the group to be added.

Eg; If a user has group.test1 but I want to add group.test2 and have it automatically remove the child group.

Without removing ALL groups incase they have a paid role

tardy quail
#

I think fixed it like this:

// Get all groups inherited by the new group
Set<String> inheritedGroups = group.resolveInheritedNodes(QueryOptions.nonContextual()).stream()
    .filter(NodeType.INHERITANCE::matches) //Get inhertiance nodees
    .map(NodeType.INHERITANCE::cast) // Filter out null
    .map(InheritanceNode::getGroupName) // Extract group names
    .collect(Collectors.toSet());

// Remove the groups
user.data().clear(NodeType.INHERITANCE.predicate(
        inheritanceNode -> inheritedGroups.contains(inheritanceNode.getGroupName())
));

Having some issued with the REST API. I am seemingly able to use it to do everyting i want, and i can confirm the changes done from the API are stored on the database, however the actual permissions doesn't seem to take effect unless i reboot the minecraft server i am testing on. /lp sync doesn't work either. Using in-game commands for promotion and demotion works instantly. Am i missing some command or setting?

hi, i'm trying to use an external bot to modify luckperms database
currently, the system in question is using mariadb+rabbitmq, and i'm trying to make a discord bot to change some things (like user groups and permissions for example (yes i know, there is existing solutions, however the planned use case demands a custom made one))
i figure i have to send an update message through rabbitmq after modifying database, but its not immediately apparent to me what kind of data i should send
could someone give me a quick rundown of the classes inside api.messenger.message.type package (https://github.com/LuckPerms/LuckPerms/tree/master/api/src/main/java/net/luckperms/api/messenger/message/type) so i can save myself from a couple of hours of reverse engineering?

it doesnt actually apply any changes or include what was changed

Hi
I am developing minecraft website im thinking of using next js for frontend and i haven’t really thought about the backend yet. I was wondering how to automate rank purchase.

For example when user buys a rank which gives certain commands this process is automatically done and given to that user. Instead me manually checking who bought what and manually giving them the rank they bought.

I know a website called tebex does it where you easily set it up but I really dont want to use tebex. Plus I want to use this opportunity to learn about plugins, api etc

Is this process done through lucky perms api? If yes how?

java.lang.NoSuchMethodError: 'java.util.List me.lucko.luckperms.common.config.generic.adapter.ConfigurationAdapter.getKeys(java.lang.String, java.util.List)'

Secondly, it seems due to using mongodb+rabbit for x-server perms messaging/updates, my LP velocity updates are also propagating out to all the LP paper servers, how might I prevent that?

fast delta
#

you can't stop those messages from being logged to the console of where it originates from, but you can stop it from being broadcasted to players and sent to other servers, https://github.com/LuckPerms/LuckPerms/blob/7744913df2e8e2ad1670fd3374c47c80143fcb64/bukkit/src/main/resources/config.yml#L253-L261
i'm not sure what you mean with the velocity updates; updates caused in any LP instance will be propagated to all other LP instances in case any of the changes affect the resolved permissions loaded in any other LP instance, that's what the messaging system is for

karmic dew
#

well i have 2 proxies, both on LPV, then N SMP paper servers, with regular LP, the LP servers are hearing about the LPV updates which I wouldn't want crosspollinating

#

I suppose it makes sense as to why but is the only solution to, dunno, have a different rabbit vhost or something?

karmic dew
fast delta
#

yes, set those two settings to false in every LP config, proxy included

karmic dew
#

with push-log-entries: false, will they still update each other appropriately though?

#

or is this some separate messaging service (not rabbit, etc)

#

oh push logging entries

Isn't this how you check if a User has a permission?

                        user.getCachedData()
                            .getPermissionData()

#

user being a net.luckperms.api.model.user.User

#

This seems to only resolve inheritance up to 2 layer, which is super weird

#

Oh. Interesting. It only doesn't work for a specific rank...
I'll do some debugging

#

Ok yeah it's me being a dummy and mistyping a permission...

#

I do have one question however, which event is the best to use to listen to permission changes?
I found the LogBroadcastEvent, however that fires for each log message, which is a bit much. I only need it to fire once per edit (like if in the editor there are multiple changes=

@slender talon could you try adding a listener to the UserUnloadEvent and printing a stack trace? I am failing to reproduce this issue myself, with a little bit of hope the event is called and that'd be of help

thonk the housekeeper unload is after you logged out and before you logged in, right? cuz the join is happening afterwards

slender talon

I left, after the data was unloaded and then when I logged in it unloaded my data then I had the bug

fast delta
#

hold up, how long does it take you to log into the server thonk

slender talon
#

it's a big big server

#

It's an open source server created by a French YouTuber, and he has a Minecraft company and they are the ones who provided us with this server.

that doesn't really answer my question lmao

slender talon

...I'm going to guess that's significantly longer than the housekeeper's threshold, since logging in should take a matter of seconds

What is a housekeeper? Sorry, I'm French, my translator is telling me nonsense.

The task responsible for unloading offline Users. Users remain in memory for at least 5 minutes after they were last interacted with via the API, or a time period I'm forgetting after they disconnect

slender talon
#

oh ok

wild whale
#

Ok dug it up, looks like the standard unload time is 1 minute, which is shorter than 1:07, so that's why the user isn't present

slender talon
wild whale

...and reading is hard apparently, I read your message as 7 minutes not 1:07. Looks like the effect is still the same though

slender talon
#

ah

fast delta
#

yeah there's something in there holding you up for over a minute, and that's enough time for LP to automatically unload the User because it did not quite finish logging in

#

at that point you gotta find out what that thing is as it's outside LP's control :/

Well, it's a bug, so lol, imagine that on a server of 200 players there will be one person who has this bug.

the issue is that some plugin is causing logins to take over a minute

Yes, I agree, but it happens once in 200.

fast delta
#

might be a ping thing, i'm surprised that the client is able to take that long to log in

#

but it's left in this limbo state during login where they don't really finish logging in, so luckperms cannot register them as online

#

hmm

#

i forgot this setting existed; could you enable the debug-logins setting and share the log section when this issue happens during login

I am also kinda curious how you are consistently reproducing this issue, lol

myeah,, there is something outside oḟ luckperms that is holding onto the login process, preventing it from finishing? the UserHousekeeper will not clean up the Users as long as the player is online but, at that point the player is not really online, so a minute goes by and it gets cleaned up

slender talon

#

a plugin or a client mod, or if you are using bungeecord/velocity it could be a proxy plugin
does login take a minute with luckperms as the only plugin on the server?

Oh I have to know! ItemAdder applies a resource pack, and sometimes it takes a long time, the bug may be caused because of that.

fast delta
#

interesting

slender talon
#

I think the solution is to make a connection with ItemAdder which checks if there is ItemAdder and when the resource pack is loaded then you launch the last phase of the housekeeper

main dagger
#

because if that is the issue in your case, it wouldnt surprise me if the same thing happened with applying any resource pack it took long enough

flint willow
#

Would there be a setting in the configs somewhere to make UserHousekeeper wait longer than one minute to clean up players? That might fix iambibi_'s issue.

slender talon
#

otherwise try joining a server with a very very heavy resource pack in order to try to exceed 1 minute

flint willow
main dagger
#

"pretty sure" based on speculation is not confirming a bug. id think that if loading a big resource pack alone with no other plugins causes LP to unload the user, thats an LP bug

slender talon
#

Do you really want me to test this?

fast delta
#

i mean, it sounds probable that it can be caused by bombing the client with resource packs during the configuration stage, not specific to IA

#

adding a setting for the housekeeper timeout would "solve" the problem, but it's grunt patchwork than a proper fix

slender talon
#

yes it is related to the resource pack application, it is not specific to ItemAdder

flint willow
slender talon
#

So the bug fix can be launched? Is it possible to have an issue/pr to have concrete progress on the bug fix?

flint willow
#

If you want to test to see if that is what your issue is to make sure firet, then take out a few plugins (just temporary) that are safe to remove to get load times under a minute and see if it works. I'm unsure if they found a fix because he was only over by 3-7 seconds about every 5th login. I think he managed to tweak a few setting to bring it under a minute reliably. I can try to research it and see if I come up with anything. No idea because I haven't experienced that myself yet.

fast delta

what

flint willow
# fast delta what

About a UserHousekeeper function somewhere that unloads players taking longer than one minute load into a server.

fast delta

sure, but your message doesn't make much sense to me xD

flint willow
#

Oh lol I was responding to iambibi who I think(?) was asking me about testing or a patch. He was running into that issue and I just meant a quick test would be to remove some plugins to see if he can get user load time under a minute and see if that fixes it. Then he'd have a better idea if that is definitely his issue.

flint willow
# slender talon so?

Hey there. I'm still unsure if you're replying to me or not lol If you are referring to me, I don't have a guranteed fix for you, but I can explain it a little better and try to help.

You're players are being timed out by the UserHousekeeper function is in the .class files of LuckPerms because it takes longer than 1 minute for them to fully load in. I think that could be altered to extend the time that LP waits for a user to login before unloading them if they take too long. That would have to be done by getting hold of the original .java files to make an edit before changing it into a .class file and recompiling the plugin.

The best thing would be for LP devs to implement some type of solution (maybe a config option for server owners to increase the time?)

For now, I think your only workaround is going to be trying to get player load time under 1 minute. The easiest way will be to simply remove a few plugins you are ok going without (at least temporarily) and see if you get the time for the player to fully load in down under a minute. That would fix your issue until the devs could respond about whether they would consider extending the time on the UserHousekeeper function or adding the ability for server owners to set the duration.

Kind of a long shot alternative here, but some plugins that add new items compatible with bedrock clients have optional .mcpacks that can be placed in the geyser folders to ease the burden on the client side. That might decrease the time for the player to fully load in (slightly). Might try that if you're only a few seconds over.

There is also a product called Resource Pack Manager that will let you combine resource packs. It's meant to try to avoid conflicts, but can have the side effect of helping to streamline your stuff a little bit as well.

slender talon
flint willow
# slender talon But I've said everything, I think they have an idea of ​​how to reproduce the bu...

Well, nobody knows who you are asking questions to without some context. You're mostly replying at yourself and haven't had any one specific person dedicated to helping you. Are you sure the devs know you're waiting for them specifically to respond to you?

I was just trying to help, but again, the lack of context around who you're talking to in your responses makes it difficult to know who you're talking to about which subject.

slender talon
#

I don't even know what you are? A luck perm developer?

#

So I found a bug with UserHousekeeper.
If you have a very slow connection (more than 1 minute), often caused by loading a resource pack, then the username isn't loaded and this error occurs: java.lang.IllegalStateException: Unable to get a user for CraftPlayer{name=iambibi_}

So I'm asking you (the luck perm developers) this question.
Can the bug be fixed? If so, should I file an issue on GitHub?

flint willow
# slender talon Well, I'm going to give you the speech again as if I were new...

I'm not a dev, just one of the many people using the product that doesnt mind trying to jump in and help others out, as is pretty common in any game modding community.

Always feel free to search guthub issues and post there id it isn't already an open issue. They definitely want to make it as issue-free as they can for as many people as they can. They won't mind.

I'm certain this is an issue the devs can fix, just likely is something that has not occurred enough to be brought to their attention as an issue needing addressed.

slender talon
#

yeah but hey if they want me to pay them to fix this very annoying bug on a 100 player server well...

flint willow
#

I definitely get the frustration when it is dealing with a server handling that many players. I can make a post in the support channel and tag you for devs to try to follow up on? I think they keep up with people needing troubleshooting there a bit better.

I could definitely be wrong, but I don't think there's ever been anything paid related to LP?

slender talon
#

I don't think there were any payments around Luck Perm.

flint willow
#

Oh ok. I was just confused on the comment about paying them to fix it lol

flint willow
#

I went ahead and tagged you in a post in the support channel so that hopefully you'll get a better dev response. Hope they get you fixed up.

So basically, I want to have 4 custom Minecraft events that are triggered through LuckPerms. (Platform independent)

First, there’s PlayerPermUpdateEvent – this one should fire whenever a player’s permissions change.

Then PlayerGroupAddEvent and PlayerGroupRemoveEvent – pretty simple, they trigger when a player gets added to or removed from a group.

And last, PlayerTeamUpdateEvent – this should only fire when stuff like the player’s prefix or suffix changes.

how do I check if a group/player is inheriting a certain permission from another group (rather than that specific group/player being allowed that permission)... while still taking wildcards and stuff into account (so I can't just check the raw permissions list)?

My approach was to query the permission, then check if the group had the returned node
however, while testing my plugin, this seemed to falsely think that the permission was inherited... once (so I can't reproduce it)
but it shows that this method doesn't appear to be reliable?

So is there a better way to handle this?

LuckPerms does not perform any chat/tablist formatting of its own!

LuckPerms only acts as the source for prefixes / suffixes, it doesn't actually apply them. You need an appropriately configured chat/tablist formatting plugin for them to be displayed. If the values appear correctly when you run /lp user <user> info, LuckPerms is doing its job!

Is there any way to make context calculation work for offline players? I'm on Paper

#

Also, why does it rely on platform player instances instead of LP's User instances?

fast delta
#

you can't "make context calculation work for offline players", but you can make a QueryOptions with a certain ContextSet to it (see the static factory methods in QueryOptions), then pass that QOpts to CachedDataManager#getMetaData/getPermissionData

#

and the reason you need an active player instance for the context manager and calculators is because, a User is basically just a simple NodeMap holder with a UUID attached to it, there is no context (ha) you can really get from it to make a useful context calculator work with

#

(probably, i wasn't there when this was designed)

celest acorn

I was trying to apply an inheritance node conditionally based on custom dynamic context, turns out my context calculator isn't even called for offline players because the subject type is Player and doesn't exist

celest acorn
fast delta
#

well, does your context calculator make use of the Player instance? or is it a StaticContextCalculator?

celest acorn
fast delta

can't you just calculate that context result directly given you have the id, and build a QueryOptions with it before passing that to getMetaData/getPermissionData?

user.getCachedData().getMetaData().getMetaValue(key, valueTransformer).orElse(ifEmpty);

Or does it respect it already? Because I don't see any way of specifying the server name

If I'm not mistaken that should already respect the user's active context. If need be, you can explicitly specify the QueryOptions on the getMetaData call

hello i am building a team plugin and i want to use placeholders as prefixes on placeholderapi parse command i can see them but when i try to use it as a prefix in luckperms it won't work someone any idea to fix this?

wild whale
#

If you mean you're putting a placeholder in the prefix you set in LP, that won't work under normal scenarios. LP will not apply PAPI placeholders anywhere, and display plugins have no reason to recursively apply placeholders when displaying prefixes/suffixes.

how am i supposed to display a team name for someones name

You should provide your own placeholder if you want to manage your own display thing in addition to normal prefixes

Hey, thanks for quick reply, this is what I ended up using, however it returns [] every time, do you know what might be the issue?

private List<String> getPlayerGroups(Player player){
        if (luckPerms == null) return EMPTY_LIST;

        User user = luckPerms.getUserManager().getUser(player.getUniqueId());
        if (user == null) return EMPTY_LIST;

        var options = QueryOptions.builder(QueryMode.NON_CONTEXTUAL).build();

        var r = user.resolveInheritedNodes(options).stream()
            .filter(node -> node.getType() == NodeType.INHERITANCE)
            .map(Node::getKey)
            .filter(t->t.startsWith("groups."))
            .toList();

        getLogger().info("[LINKDEBUG] Found " + r + " groups.");

        return r;
    }
fast delta
#

what's the point of the .filter(t->t.startsWith("groups."))?

#

all nodes are InheritanceNodes at that point so the filtering doesn't really make sense to be there at all

#

but, that's what is wrong, because inheritance nodes are group.foo instead of groups.foo, but you don't even need this filter so you can just get rid of it

Hello, I am trying to build a Velocity chat plugin with leverages Luckperms prefixes/suffixes and am struggling to fetch them from the api. When I attempt too I get an error telling me the Luckperms API hasn't loaded yet. I have only been able to find very limited information on implementation so any pointers are welcome as well.

As a bit of context this is being called on a PlayerChatEvent, if more information would make it easier don't hesitate to ask! 🙂

    private String getLuckPermsPrefix(UUID uuid) {
        LuckPerms api = LuckPermsProvider.get();
        
        User user = api.getUserManager().getUser(uuid);
        if (user == null) return "";

        CachedMetaData metaData = user.getCachedData().getMetaData();
        String prefix = metaData.getPrefix();
        
        return prefix != null ? prefix : "";
    }

Hello!

For a Discord/MC role sync plugin, I want to perform an action for each group added/removed to the player. To do this, I thought the NodeAddEvent and NodeRemoveEvent events would be appropriate, as groups are symbolized by permissions that start with group.. But the add/remove parent command doesn't trigger these events. I still can use the UserDataRecalculateEvent instead, but I'm afraid it might be triggered too frequently in my case. Just to be sure, am I missing something else that would fit better?

Thanks a lot!

night pier
#

Use NodeMutateEvent, and Event#isGroup

#

no im lying

#

isGroup would only work if you were modifying a group

fast delta
#

those commands should certainly fire the events

night pier
#

if the plugin listening to it is on the same server it was fired on, yeah

charred rover
#

The 3 events I mentioned are triggered if I add/remove a permission to the player with permission set/unset command, but if I add/remove a group to him with parent add/remove command, I only have the UserDataRecalculateEvent triggered. My plugin is of course on the server where the command is executed. Anyway, it seems to work as intended with the NodeMutateEvent, so I'll probably use that one. Thanks a lot! 😄

LuckPerms does not perform any chat/tablist formatting of its own!

LuckPerms only acts as the source for prefixes / suffixes, it doesn't actually apply them. You need an appropriately configured chat/tablist formatting plugin for them to be displayed. If the values appear correctly when you run /lp user <user> info, LuckPerms is doing its job!

What is the easiest and best way to sort LuckPerms users based on weight from meta data?

slow swift

I just wanted to check to see, but does this only return TRUE if the player has that permission node or does it also look for wildcards?
Like, if I check for test.example.permission.node and they dont have it, but they do have text.example.permission.* would it return UNDEFINED or TRUE
CachedPermissionData.checkPermission()

Ok so ive gone through this for like hours since last night

#

TSSM Access Guard is a mod I made for Fabric 1.21.1 that blocks players from using Tom’s Simple Storage terminals unless they have a specific permission.

I built it for my server to make sure only trusted players can access shared storage. If they don’t have the right permission through LuckPerms (or any mod using fabric-permissions-api), the terminals just won’t work for them.

#

I'm trying to build a Fabric mod that uses Lucko's fabric-permissions-api version 0.3.1, but I'm getting a Could not find error during the Gradle build. The artifact is available on Maven Central — I can access it in the browser at the correct path — but Gradle still can’t resolve it. So the issue persists even though the dependency exists online.

#

this is my first experience doing any mod and my first experience using java

all of this code is ai built so keep that in mind

# unborn orbit Hey! This possible collect `NodeAddEvent` and `NodeRemoveEvent` in Velocity? If ...

In a network setup when modifying LP data, all the normal events for that modification only fire on the LP instance that the changes were made on. Every other instance will only get the network sync events. For instance, if you have servers A & B behind a proxy and a LP command is ran on server A, server A will fire the normal NodeAdd or NodeRemove or whatever events, while server B and the proxy will only get the network update related events.

exists a event trigger when the modification occur?

Is it possible to alter the way LuckPerms gets the players UUID to intercept it and replace it with a different value?

#

I'm aware how crazy this sounds haha

main dagger
#

altering uuids is not supported

supple seal
#

Is there any way to alias UUID's?

wild whale
#

No, that would fall under "altering UUIDs". The whole contract of a player's UUID is exactly one UUID maps to exactly one player, and that said UUID will never change. Attempting to modify it will break all sorts of things beyond just LP.

What are you actually trying to accomplish? There's probably a sane way to accomplish your goal without messing with UUIDs

supple seal
#

We're trying to make our character switcher less janky w/ a Velocity plugin that creates entirely separate "users" for each. Our previous implementation felt pretty fragile since it was copying around items, potion effects, etc.

wild whale
#

Yeah so modifying UUIDs is definitely not the way to go for that, that moves you into even more janky territory. At least for LP, providing a custom context calculator might be a more reasonable alternative? You could provide a context that's i.e. character=<who>, then set any permissions that depend on which character is selected with the appropriate context. This also means you can set any permissions that don't depend on which character is selected (i.e. staff groups, any purchased perks, etc) without a context, so they always are active regardless of selected character.

#

!context
Below is the documentation of context intended for admins configuring LP, and here's the documentation section for registering your own context calculator via the API

Why not make LuckPerms work on older versions of Forge?

Forge added the Permissions API only recently in 1.18. That API is what allowed a native Forge version of LuckPerms to be made, however that API does not currently exist on older versions of Forge, and is unlikely to be backported. Without the Permissions API existing on older versions of Forge, it is impossible to make LuckPerms work on those versions of Forge natively.

Is there any other option?

There is a Sponge version of LuckPerms! You can add SpongeForge and the Sponge version of LuckPerms to use LuckPerms on older Forge versions.

Offline mode/cracked servers

Running a Minecraft server in offline mode can cause a lot of issues, particularly with UUIDs and security vulnerabilities. Some people also view it as unethical (piracy). We understand that some people need to run their servers in offline mode. However, due to the reasons mentioned, some users will choose to not support those running a server in offline mode (this does not apply to those running in a Bungeecord network). Please respect their decision, you may continue to seek help for your issue but in most cases, it can be resolved by setting online-mode=true in server.properties.

Hello,

I've been trying for several days to add LuckPerms as a Gradle dependency in my IDE for a Forge 1.20.1 mod, but I keep encountering compilation errors during development.
However, when I run the mod on an external server (outside the IDE) with LuckPerms installed in the mods folder, everything works fine and the mod starts without any issues.
Is there something specific I need to do to include LuckPerms properly as a dependency during development?
Thank you in advance for your help.

there is a sync event though, you can use that but you have to figure out what changed on your own

I'm having some issues using the LuckPerms API:
whenever I want to promote a player (adding a new group but also deleting the old one) I use this code:

u.data().add(Node.builder("group.friend").build());
Main.lp.getUserManager().saveUser(u);
u.data().remove(Node.builder("group.default").build());
Main.lp.getUserManager().saveUser(u);```
but sometimes the player has two groups afterwards...my best guess is that its caused by the LuckPerms methods being called asynchronous but does someone know how to work around this problem?
#

*my only idea is to run the lp user name promote command via console but doing that in a plugin is kind of weird...i think🤷‍♂️

fast delta
#

well, first you don't need to save the user data after every individual change lol, you should do all the changes and then save the user
but for this you can get the Track from the TrackManager and then call Track#promote

snow willow
#

Thanks a lot

#

can I put in null into the context field when I don't want any specific context or is there an identifier for "no-context"?

#

*and do I also need to call saveUser() afterwards?

wild whale
snow willow
#

Yeah thats exactly what I needed thx

wild whale
#

As for saving...I'm honestly not sure. My gut says probably, but I'd need to check the source

snow willow
snow willow
wild whale
#

"global" just means no context, there's no actual "global" context

snow willow
#

Oh ok

#

that makes sense...thx

wild whale
#

Ok yeah quick 2 minute look at the implementation, there's no obvious saving happening. As long as you're not calling this several times a second, it shouldn't really matter anyways

snow willow
#

ok so theoretically I need to save it but it only matters if I make many different changes fast?

#

and also why does the following code end up in the user having two groups? (the old one and the new)

                Main.lp.getUserManager().saveUser(u);```
chilly condor
# main dagger events only fire on the server the change occurs on

I figured it out using UserDataRecalculateEvent, since that occurs on all servers it seems.

subscribe(UserDataRecalculateEvent::class) { onUserDataRecalculate(it.user) }
// ...
    private fun onUserDataRecalculate(user: User) {
        val now = user.getInheritedGroups(QueryOptions.nonContextual())
            .map(Group::getName)
            .toSet()
        val before = groupCache.get(user.uniqueId) { emptySet() }

        if (now == before) return
        groupCache.put(user.uniqueId, now)

        (now - before).forEach { modifyNode(user, it, added = true) }

Is PermissionNode.builder("test").expiry(Duration.ZERO).build(); going to create a permission node which doesn't expire?

Is it possible to create a transient group or add transient permission nodes to the player?

no, it's going to create a permission that's going to expire in 0 seconds (so, already expired basically)

you don't need to define an expiry at all if you don't want one

I am making a plugin that can create different "profiles". Basically, when a player is logged into a profile, their UUID changes (modifying the GameProfile using NMS).
However, LuckPerms seems to break when that happens. It's not working when a player doesn't have the UUID it is supposed to have.
I tried to invalidate cache when switching profile, to no success.
Would it be possible to have different permissions based on what profile is currently selected? Knowing that the username doesn't change, but the UUID does.

wild whale
tacit solar
#

Yeah I did try contextcalculators first. It worked, but it really only works for luckperms. My goal is to make all the other plugins automatically support each character, by assigning new data to each new profile based on the UUID. Right now, my server is mostly plugins that I made myself, so I could technically store all the data in a way to would work with this system. However, we are probably going to have at least one plugin that doesn't support it, that is made externally and that we just don't really have any control over. So that's why modifying the UUID seems like the most logical option. Right now I am almost there, just need to refresh luckperm's cache and Permissible injector. Thanks though.

If a player has multiple ranks that has permissions like plugin.perm.1, plugin.perm.2, plugin.perm.3 etc. does Player#getEffectivePermission(); return all of them?

I want to add a list of permissions, but I want the event to be triggered only once so that my plugins don't have to process the event 20 times

wild whale
#

Yes I figured that from your original message, I'm asking why the event being processed 20 times is a problem - this is implying there's a larger problem at play

#

Like there's plenty of reasonable situations where 20+ permission mutations can occur at once outside of whatever you're doing, so if your system can't handle that then you're probably going to encounter problems regardless

isn't there a method to add a Stream of permissions?

LuckPerms does not perform any chat/tablist formatting of its own!

LuckPerms only acts as the source for prefixes / suffixes, it doesn't actually apply them. You need an appropriately configured chat/tablist formatting plugin for them to be displayed. If the values appear correctly when you run /lp user <user> info, LuckPerms is doing its job!

Hi, I did something like this (it's in Skript but you will probably understand).

  1. I got the duration of node: set {_expiration} to {_node}.getExpiry()
  2. Then I'm getting remaining time: set {_remaining} to Duration.between(Instant.now(), {_expiration}).getSeconds() + 1
  3. At the end I'm formatting remaining time to timer format: secondsToTimer({_remaining})
    if {_num} >= 10:
        return "%{_num}%"
    
    return "0%{_num}%"


function secondsToTimer(seconds: number) :: text:
    set {_totalSeconds} to {_seconds}
    
    set {_days} to floor({_totalSeconds} / 86400) # 24*60*60
    set {_hours} to floor(mod({_totalSeconds}, 86400) / 3600)
    set {_minutes} to floor(mod({_totalSeconds}, 3600) / 60)
    set {_seconds} to mod({_totalSeconds}, 60)
    
    set {_d} to timerFormat({_days})
    set {_h} to timerFormat({_hours})
    set {_m} to timerFormat({_minutes})
    set {_s} to timerFormat({_seconds})
    
    return "%{_d}%:%{_h}%:%{_m}%:%{_s}%"```
    
    
But when I add myself node for more than 1mo, the time I get from lp placeholder and from this function is different. Do you know why?

I'm a bit confused on the Value part of a Node.
Like for a PermissionNode, is the value as simple as "true = has permission and is true; false = does not have permission OR has permission, but is set to false", or is there more to it?

My goal is to return whether the player has the permission, and said permission is actually true/granted.

I can't use stuff like the hasPermission method on Servers/Proxies because A) I'm designing this in a way that works platform independant and B) the Player is not available when I want to check this (It happens while they ping the server/proxy from their multiplayer screen)

fast delta
#

the value of a Node is the explicit value granted to it, true or false
a Node having a value implies the existence, the presence of the node, so if you have a Node that you got from a User, then the node is present to begin with

ripe thorn
#

Actually, I made an obviousl logic error.
If the user does not have the permission assigned, then they obviously don't have the node.

fast delta
#

yep!

#

you got that right

#

true/false/not set

ripe thorn
#

I assume I would obtain the CachedPermissionData via getCachedData().getPermissionData() of the User object?

fast delta
#

yep

ripe thorn
#

Would this be recommended for group checks too, or would streaming over getInheritedGroups be a better aproach?

fast delta
#

that check includes inherited nodes by default

#

as if performed by a regular hasPermission check on the platform's permission api (bukkit's Player#hasPermission etc)

Something I wonder.
When calling loadUser, will the return CF always be a new one, or does LP cache it for a while?

hi. I have created a lil helper methods for adding permissions:

        Main.lp.getUserManager().modifyUser(player.getUniqueId(), (User user) -> {
            PermissionNode permissionNode = PermissionNode.builder(permission).value(value).build();
            user.data().add(permissionNode);
        });
    }

    public static void setPermissionForUser(OfflinePlayer player, String permission, boolean value, int durationSeconds) {
        Main.lp.getUserManager().modifyUser(player.getUniqueId(), (User user) -> {
            PermissionNode permissionNode = PermissionNode.builder(permission)
                    .value(value)
                    .expiry(Duration.ofSeconds(durationSeconds)) // Temporary permission
                    .build();
            user.data().add(permissionNode);
        });
    }```

First one works great, but second one adds "default" parent group when executed, and I don't get why
wild whale
#

Did the player have any other permission data before you added the temporary node?

(Side note, static abuse. Neither of these methods nor Main.lp should be static )

inland briar
#

Yes, it has. Actually, it happens only if I call that method twice, i.e. for different permissions:

Util.setPermissionForUser(victim, "cmi.command.warp.koth", false, times * 60);    Util.setPermissionForUser(victim, "cmi.command.warp.spectate", false, times * 60);

(I'm a recovering staticholic)

hey, i keep getting this error whenever I try to call LuckPerms api = LuckPermsProvider.get();
i have shadowJar'ed the dependency into my plugin and i have the luckperms plugin installed on my server. This method is also being called in a command, which means the plugin would have been enabled by now.
do i need to include a dependency in my plugin.yml maybe?

image.png
wild whale
wild whale
#

(This doesn't just apply to LP fyi - if you're depending on any API provided by another plugin, you can't shade it)

#

Oh, but also yes, you do need to declare an [optionally soft] dependency on LP in your plugin.yml

dawn cloud
#

Ah ok, that’s my bad I thought APIs were the same as any other dependency

#

How do you use softdepend? Do i need to check if the luckperms api class exists or not in my code?

#

Because if I don’t shadow jar it it gives class not found errors

wild whale
#

Use a normal dependency in your plugin.yml if you require LP to be present. softdepend is an optional dependency (i.e. your plugin can work without the other plugin, but if it's installed then you do use it), while depend is a required dependency (if it's not present, the server will throw an error and your plugin won't be enabled).

#

If you require LP for your plugin to work, you can just make it a hard depend & you know for sure LP will be loaded when your plugin is enabled. If it's optional, then yes, you'll need to do some extra steps to handle that.

#

As for the ClassNotFounds, check your server's logs; make sure a) LP is actually getting enabled, and b) it should be getting enabled before your plugin

You definitely shouldn't be doing that sleeping thing, that's super unreliable. Common problems:

  • Make sure you are not shading LP (declare the LP API dependency as compileOnly in gradle / with the provided scope in maven)
  • Make sure you've declared a dependency on LP in your plugin manifest file (whatever bungee calls it)
  • Make sure LP is actually running on the test instance

Not about API, but: if I decide between online/cracked authentication on velocity in preloginevent, does luckperms save user uuid after this event, during or before? (So premium users won't have offline uuids in db etc.)

#

It's kinda hard for me to test it, but my point is to allow premium players and cracked players with password onto my server using PreLoginEvent and I wonder if luckperms will work fine or will it check/save etc. Uuids at this event (and do it potentially before I change user from Mojang authentication with premium UUID into cracked account with offline uuid). I'm talking about velocity

wild whale
#

Modifying UUIDs is not supported, doing so is almost always a 1-way trip to data loading errors.

drowsy forge
#

I'm really not modifying it at all. Rather I'm changing between authenticating them (premium) and not authenticating them (cracked), which to my understanding changes their uuids

#

Okay, maybe different question: is luckperms doing something during preloginevent or before it? And if it is, then what?

wild whale
#

I'd suggest taking a look through the code yourself, it sounds like you have at least a rough idea what it is you're looking for. All the platform modules are relatively small and simple, so it shouldn't be too hard to find the relevant stuff in the velocity module

I have good enough knowledge to know it could be a problem and to know how to ask a question and to know that i don't know what the f I'm doing with velocity

But from what I see luckperms does it's stuff after preloginevent

#

So it should be working alright

I am trying to listen for events when a user gets a permission added or removed.

Setup:

  • Minecraft server with the LuckPerms plugin installed (this is where I’m editing the user’s permissions)
  • Redis is set up
  • PostgreSQL database where the LuckPerms data is stored
  • LuckPerms REST API connected to the database
  • LuckPerms REST API Java client connected to the REST API

I have verified that the Java client is working (LuckPermsRestClient.groups().list().execute() returns all my groups).

I thought I needed to subscribe to the LogBroadcastEvent to detect when permissions are changed on the Minecraft server. Is this assumption correct, or are the events only triggered when changes are made via the REST API, and not on the server, because there is no Redis connection between the REST API and the Minecraft plugin?

I looked at https://github.com/LuckPerms/rest-api-java-client/blob/main/src/test/java/me/lucko/luckperms/rest/EventServiceTest.java

import net.luckperms.rest.LuckPermsRestClient;
import net.luckperms.rest.event.EventProducer;
import net.luckperms.rest.model.LogBroadcastEvent;

public class LogBroadcast {
  public static void main(String[] args) throws Exception {
    try (var client = LuckPermsRestClient.builder()
        .baseUrl("http://127.0.0.1:6457/")
        .apiKey("LH5dRq2koqE792RSWGAb4MKmPGe5d99X")
        .build()) {

      EventProducer<LogBroadcastEvent> sub = client.events().logBroadcast().subscribe();
      sub.subscribe(e -> System.out.println("[LogBroadcast] " + e.origin() + " " + e.entry()));
      System.out.println("Listening for LogBroadcast events...");
      Thread.sleep(300_000); // keep alive 5 min
    }
  }
}

Or is what I’m trying to do not even possible? Do I need to listen to Redis Pub/Sub with my Java application to detect changes made on the Minecraft server?

wild whale
# celest sable What is the latest luckperms api version

Latest API version is 5.5. If you're getting a NoClassDef, that's unrelated to a version mismatch though; make sure you've declared a dependency on LP in your plugin/mod manifest (i.e. on Paper that'd be your plugin.yml or paper-plugin.yml) & that LP is actually starting up before your plugin/mod

does LuckPerms API have any way to retrieve a group's prefix as an Adventure Component? or am I stuck guessing whether the user used legacy or MiniMessage in the field?

night pier
nimble hawk
night pier
#

highly unlikely.
what's the use case of this, just so i understand better what you're attempting to do?

nimble hawk
#

it is for a placeholders thing, I was aiming to not have to parse legacy format if I could help it but I guess there's no escaping it if there are plugins which will inevitably support it still

night pier
#

this also isn't really a "one or the other" situation.
plugins can support literally any format they choose, even if they use ! in place of the & or section symbol.
it's easier to allow them the option, than to try and limit what they can do.

I feel like I've overengineered but this is my way of getting the highest weight-node a user has:

            try{
                return Integer.parseInt(x.split("\\.")[1]);
            }catch(Exception ex){
                return 0;}
        }).max(Integer::compareTo).orElse(0);```
...is there any shorter/cleaner way?
#

*or precisely getting the actual weight of the highest weight node

#

and as an explanation:
first I take a collection of every node and map it to the key
then I filter for the weight nodes
then I map them to the actual weight while all weight nodes that doesnt look like this weight.xyz (where xyz is an int) are castet to 0 through the exception parseInt throws when encountering unvalid ints in the string
I now take the Collection of Ints (the weights) and put them (as a list) in the Collections.max function to get the highest weight of the user

snow willow
#

...nvm
for anyone wandering the same (especially for future reference cause I don't know if this is wide knowledge)

Although there isn't a method for getting a users weight, there is one for getting a groups (since weights are nodes specifically for groups)
That means it suffices to get a players primary group and get its weight like this for example:
Main.lp.getGroupManager().getGroup(Main.lp.getUserManager().getUser(p.getUniqueId()).getPrimaryGroup()).getWeight().orElse(0);

#

*and if someone has an even cleaner solution please let me know👍

LuckPerms does not perform any chat/tablist formatting of its own!

LuckPerms only acts as the source for prefixes / suffixes, it doesn't actually apply them. You need an appropriately configured chat/tablist formatting plugin for them to be displayed. If the values appear correctly when you run /lp user <user> info, LuckPerms is doing its job!

FAQ answer: Prefix isn't showing?

No need for placeholders. Just use a chat/tab plugin which supports the format

cold harbor
#

No i mean i am coding a plugin in which you can change your prefix for example from &6Player -> &4Player

Oh yea, but it basically results in the same. You technically dont have to use placeholders. You just need to support and parse the format

Wouldn't it be much simpler if you were using API#getGroupManager#modifyGroup(name, consumer)?`
https://luckperms.net/wiki/Developer-API-Usage (here are quite a few examples you can find)
https://github.com/LuckPerms/api-cookbook/blob/master/src/main/java/me/lucko/lpcookbook/commands/SetGroupCommand.java#L56 (yet another example of how to modify the users group)
I feel like you're holding and modifying the cached group which is shared across the whole server, or not really waiting for a user to be loaded

https://javadoc.io/doc/net.luckperms/api/latest/net/luckperms/api/model/group/GroupManager.html#modifyGroup(java.lang.String,java.util.function.Consumer)
https://javadoc.io/doc/net.luckperms/api/latest/net/luckperms/api/model/user/UserManager.html#modifyUser(java.util.UUID,java.util.function.Consumer)

Damn, my problem must be the hardest one on this discord server

gleaming pulsar
# sacred marsh yea but like is my code the reason it's shuffling permissions

Oh yea sorry forgot to answer - it indeed is.
You are holding onto the user/group even if stuff has changed. Try replacing it with #modifyGroup and #modifyUser - as already said above.
And don't cache/load the user/group - just use the functions below
https://javadoc.io/doc/net.luckperms/api/latest/net/luckperms/api/model/group/GroupManager.html#modifyGroup(java.lang.String,java.util.function.Consumer)
https://javadoc.io/doc/net.luckperms/api/latest/net/luckperms/api/model/user/UserManager.html#modifyUser(java.util.UUID,java.util.function.Consumer)

And you might as well want to drop the Rank caching, LuckPerms already has a cache built-in. Double-caching is kind of too much imo and will most likely lead to new/other issues

Hey, i was wondering if there was a way to set a transient permission for a user?
Didnt look into the unloading, but i basically want the permission to be transient on the users session (connected to proxy).

gleaming pulsar
mossy tapir
#

I would just listen for the disconnect events, but this poses the risk of fragmented permissions in case of an unplanned shutdown or crash.

wild whale
#

Yeah, transient permissions are definitely something we natively support, pretty sure it's exposed to the API too, let me check

#

Ok, yup it indeed is. Normally when you want to modify a PermissionHolder's nodes, you'd get the NodeMap from PermissionHolder#data and then modify that. For transient data, you simply use the NodeMap returned by PermissionHolder#transientData instead. You can also use PermissionHolder#getData(DataType) to dynamically grab either their normal or transient data if you want

#

Worth noting though, you said this was a network environment - as far as I know, transient data will only apply to the current LP instance (i.e. if you set a transient node for a player on the proxy, the backend server won't see it)

mossy tapir
#

Ah i see. Important to know that its not synced, but i can handle that. Thank you 😄

unique harness
#

Hello, I have a question: shouldn't UserManager#modifyUser also push update if messaging service is present?

#

it's kind of confusing

main dagger
unique harness
#

yes i know but i think it should be included in the API

fast delta
#

what should be included where?

#

you can queue an update yourself via the API already

#

there's a pinned message here as example

unique harness
#

modifyUser should also push update

#

that's my point

main dagger
#

it doesnt because you may want to update many users

#

it would be inefficient to ping for each user

unique harness
#

well there is no option for a batch database save in luckperms either

fast delta
#

batch loading and saving of users/groups would definitely be nice to have

#

but i do not think the api should be doing things without you telling it to when it is not specified

unique harness
#

we could add modifyUser(UUID, Consumer, boolean)

fast delta
#

and what is the advantage of that over.. just.. pushing an update through the messaging service?

#

like you would be adding api to that adds nothing of value and you need to call explicitly, might as well just do the thing explicitly already

#

which is already the case

unique harness
#

it would be much more clear that modifyUser default behavior does not include pushing the update

fast delta
#

then maybe it's the api contract that needs clarifying in the javadoc to mention that it does not do that, as it isn't part of the contract that it does

unique harness
#

for me it doesn't make sense why this wouldn't push a update, like in what case you don't want your data to stay in sync other than batch updates, which are not the issue here because any implementation of messenger will handle 50k< publishes or subscribes (other than sql messenger), the issue here would be the database because even if you send one push update the database still has to do X amount of inserts on the sender server and X amount of selects on receiver server due to luckperms not having any batch handling (that I know about)

fast delta
#

let's just agree to disagree

#

you need to do this manually already, adding more api that you need to call manually does not add value

#

further clarification on the existing methods' contracts, however, would

unique harness
#

yes that's correct

#

however, as I mentioned I don't see any user case where this would be non-beneficial

fast delta
#

just push the update through the messaging service

#

what's so difficult about that

wild whale
#

For what it's worth, I'd agree that an overload or some other thing to handle flushing would be some nice sugar syntax. It's like loadUser -> modify -> saveUser vs modifyUser; we don't need modifyUser since it's essentially just sugar syntax for the first option, but it's a great safety net for API consumers to ensure they don't forget to save things.

If an API break was an option, I'd go so far as to argue the default behavior should be to push an update alongside any save operations, and make it opt-out instead for those rarer cases where such behavior isn't desired

fast delta
#

why is it needed and how does it add value?

unique harness
#

It reduces the probability that API user will forget to push update. From my point of view at first look modifyUser method seems like it's doing all the work needed to save the user but it doesn't. It would also reduce lines of code that needs to be done on user end, however if you don't want this behavior you can use standard future chain. Or at least it should be mentioned in javadocs

fast delta
#

I suppose so

#

feel free to open an issue or a pr, though I will say a modifyAndPush is more.. mm, appetising than a boolean parameter overload

Does the Luckperms API have a way for you to detect when a context has changed? I can't find anything for it.

To be clear, I don't mean when the contexts assigned to a permission have changed, but when the output of a context has changed, IE a player has changed world if the context is = that world.

My use case is for Grim where we allow users to specify permissions to exempt from cancelling packets, setting back, or just fully exempting them from specific checks

https://github.com/GrimAnticheat/Grim/issues/2417

For performance reasons we obviously can't poll the permissions every time a packet comes in for every check we have

Hello, I want to register a context calculator for whether a player is muted with the LiteBans plugin. Here is my code:

public class LiteBansMutedContextCalculator implements ContextCalculator<Player>
{

    @Override
    public void calculate(@NonNull Player target, @NonNull ContextConsumer consumer)
    {
        consumer.accept("litebans-muted", Boolean.toString(Database.get().isPlayerMuted(target.getUniqueId(), null)));
    }

    @Override
    public @NonNull ContextSet estimatePotentialContexts()
    {
        ImmutableContextSet.Builder builder = ImmutableContextSet.builder();

        builder.add("litebans-muted", "true");
        builder.add("litebans-muted", "false");

        return builder.build();
    }

}

Unfortunately this does not work, because the LiteBans does not allow the check to be run on the main server thread. Can it be done async instead? And if so, how?

Have a cached layer for wtv liteban data you need is probably the better option, bcu context calculation should be quick and not do db queries

Hey, im implementing a hook for votifier, and i dont feel like requesting and caching Name:UUID mapping.
There is probably an easy way to access and use the cache that Luckperms maintains, right? 😄

        .getUserManager()

Wait the UUID could be null? 🙁
In what case? On a cache miss or when the username doesnt exist on mojangs end?

Could anyone please provide a rough estimate of the time it takes for LuckPerms to retrieve player data from the database and return it to the API's CompleteatableFuture? I know the answer isn't fixed depending on the context, but I'd like to hear the experiences of people who have used the API because I am just very new

#

Like under what circumstances can it be completed very quickly, in just tens of milliseconds or even instantaneously, and under what circumstances might it take several seconds?

gleaming pulsar
# little shard Like under what circumstances can it be completed very quickly, in just tens of ...

It really depends on caching and storage backend.

If the user is already cached, the CompletableFuture will usually complete instantly (0–1 ms). If LuckPerms needs to load from local storage, it’s typically just a few milliseconds.
With a remote database (MySQL/Postgres), uncached loads are usually in the 10–50 ms range on a healthy setup, but can be slower if the DB is under load or there’s high network latency.
Multi-second loads generally only happen in pathological cases (DB issues, cold connections, extreme latency, or very large/complex permission data).
The async API just ensures this work doesn’t block the main thread - it doesn’t guarantee a specific completion time.

Oh, it'll vary by storage method but shouldn't be too bad. Definitely don't run it on the main server thread, but the database-based storage methods should all be able to do that lookup pretty quickly barring any network latency. Plaintext methods are inherintly a little slower, but still shouldn't be horrible

hello, i'm looking to add LuckPerms support to my hytale plugin. the API documentation is very helpful, but i'm unclear about something. API documentation shows interaction with a Player class. but the API documentation is general, not specific to hytale. the hytale API also exposes a Player class. is the Player class mentioned in the LuckPerms API docs a game Player class or a LuckPerm class?

this is my first time using the LuckPerms API so this might be a stupid question. 🙂

jaunty pecan
#

In Hytale it’s a PlayerRef :)

#

We will update the docs to reflect that after it’s out of beta and all merged in

magic granite
# jaunty pecan In Hytale it’s a PlayerRef :)

the Player class has virutally all the same methods implemented on it as PlayerRef, and by my understanding, PlayerRef isn't even an entity class. the hytale api really confuses me sometimes lol, especially since PlayerReference ISN'T a ref. /sigh

#

but ty, you mean to say i should be calling hasPermission on the game class?

#

also just to be clear, is LuckPerms implemented on Player or ONLY on PlayerRef?

jaunty pecan
#

You can call the hasPermission methods yes and LP will handle them

#

Sorry for the confusion, your original question was about the LuckPerms API which is different

#

The methods there that expect a platform “player” object are expecting PlayerRef
