As explained on the wiki it’s for all platforms
Btw what for do you need to iterate over the permissions?
compact spruce
just making a simple plugin that formats join/quit messages and check permissions for proper prefix and suffix formatting
something set by essentials i think
part of a cross-server chat plugin
crystal sonnet
just making a simple plugin that formats join/quit messages and check permission...
Huh?
compact spruce
I'm sure such a thing already exists
so like when a player joins it says [Moderator] minecraftUserName
crystal sonnet
BungeeChat for example 😜 (which I made)
crystal sonnet
Those are prefixes
compact spruce
lol
nice
so I just need to check the permissions to get the right colors basically
crystal sonnet
The API has methods for getting prefixes and suffixes

that's just what i need

Hey!
I've been using the API for a bit, but never used the Event System which I am currently a bit stuck on.
I have read up on the Documentation Page (https://luckperms.net/wiki/Developer-API-Usage) on how to Subscribe to Events using the EventBus and basically replicated that Code in my Project.
Now whilst running a simple task of outputting a Message in Chat once the "UserLoadEvent" should be called, sadly nothing is happening.
In my Main Class I added this: new LuckPermsListener(this, LuckPermsProvider.get());
And my Listener Class looks somewhat (shortened out most of it) like this:
public class LuckPermsListener {
private Main main;
public LuckPermsListener(Main main, LuckPerms api){
this.main = main;
EventBus bus = api.getEventBus();
bus.subscribe(UserLoadEvent.class, this::onPlayerDatabaseLoad);
}
public void onPlayerDatabaseLoad(UserLoadEvent e) {
Bukkit.getScheduler().runTask(main, () -> {
Bukkit.broadcastMessage("UUID: " + e.getUser().getUniqueId());
});
}

Hey, i was trying to find a way on how to get the permission expiry time from a player's node from the LuckPerms API. I tried different ways but none of them work. and I also searched a lot in the #Developer_API wiki but I couldn't find an example similar to it could be great if somebody knows how. and share it, it will save me time. Thanks
sorry for the bad english.
nocturne elbow
How are you trying to do it currently?
nocturne elbow
Aah you see, parent group nodes are not permission nodes, they are inheritance nodes (of type INHERITANCE), so getNodes(NodeType.PERMISSION) will never give you parent group nodes :d
zealous rose
alright, i'm going to try that out
nocturne elbow
And you'd filter if the group name isn't member
nocturne elbow
Yeah, InheritanceNodes contain the group name
mossy surge
I may be tried but I fail to give myself a parent. I'm doing lpUser.data().add(linkedNode); where linkedNode is InheritanceNode.builder("linked").build(); and linked is the name of a group in LuckPerms. Am I doing it wrong?
compact spruce
I'm a little confused about how the server vs world context works
I'm using the following code to send the user their CachedPermissionData and their contexts when they type a command
public void execute(CommandSender sender, String[] args) {
if (sender instanceof ProxiedPlayer) {
sender.sendMessage(new TextComponent("You have these permissions:"));
for (String perm : sender.getPermissions())
sender.sendMessage(new TextComponent(ChatColor.GOLD + perm));
LuckPerms api = LuckPermsProvider.get();
User user = api.getPlayerAdapter(ProxiedPlayer.class).getUser((ProxiedPlayer) sender);
CachedPermissionData data = user.getCachedData().getPermissionData();
for (Map.Entry<String, Boolean> entry: data.getPermissionMap().entrySet()) {
sender.sendMessage(new TextComponent(ChatColor.GOLD + entry.getKey() + ChatColor.RESET + ": " + ChatColor.GREEN + entry.getValue()));
}
ImmutableContextSet ctxSet = api.getContextManager().getContext(sender);
QueryOptions queryOptions = api.getContextManager().getQueryOptions(sender);
sender.sendMessage(new TextComponent(ChatColor.RED + "Context set:"));
for (Context ctx: ctxSet) {
sender.sendMessage(new TextComponent(ChatColor.GOLD + ctx.getKey() + ChatColor.RESET + ": " + ChatColor.GREEN + ctx.getValue()));
}
}
my server admin has a bunch of permissions for my user set with context server: creative or server:survival
nothing is set by world. But when that Context ctx: ctxSet loop runs, it tells me the server is bungee and the world is the servername
i'm trying to figure out why the context is always bungee for server
obtuse jolt
In bungeecord yea, server is bungee, and world is your servername
compact spruce
i'm expecting it to be survival or creative
yikes. so i need my admin to redo all the permissions?
I have server: survival in the luckperms config.yml for the spigot server
so server is always gonna be bungee?
that's hard to believe because the permissions work correctly on his server using server: survival and server:creative when running under bungee
the docs also show the example "world: world_nether". It seems odd that world would represent a spigot server under bungee since those spigot servers could have multiple worlds too
config.yml
# The name of the server, used for server specific permissions.
#
# - When set to "global" this setting is effectively ignored.
# - In all other cases, the value here is added to all players in a "server" context.
# - See: https://github.com/lucko/LuckPerms/wiki/Context
server: creative
it should be the server context as far as what this says, not world. is there anyway i can make it show the spigot servers as servers rather than worlds
nocturne elbow
Not on bungee LP
nocturne elbow
The "server" setting refers to the LP instance rather than a "server"
compact spruce
I see
nocturne elbow
There is an open issue about that
compact spruce
I just don't understand how it works on on our production server since our admin has all the permissions set as server: creative, server: survival etc.
yet when i do it on my test server using the above code i get get world:survival so there is no way i can get the correct permissions
unless we redo all the contexts
as far as i can tell we have the same setup
i wonder if i can force change the player's context somehow
when players login
nocturne elbow
Everywhere, "server" refers to the specific LP instance, on the survival server it'll always be "survival", on bungee it'll always be "bungee". The "world" context however refers to "where the player is in", in Bukkit that is the actual world and on bungee that is the server name they are in
nocturne elbow
i wonder if i can force change the player's context somehow
Yeah nah
Contexts are more like a "state" that LP "observes"
Say for example you wanted to give Bungee LiteBans' perms while you were in the creative server only, you would grant them for server=bungee and world=creative
compact spruce
That's what I figured. But my server admin has the permissions set up as server: creative, server: survival and somehow they work
Not sure how
compact spruce
So you say that I cannot force change the player's context. But could I calculate and somehow return a list of what permissions they would have under a certain context?
like calculate all the permissions they would have if they were under context server: survival even if their current active contexts are server: bungee and world: survival
that would solve my problem

LuckPerms wiki
compact spruce
I've been reading the docs for hours and I can see how to query permissions for an active context, but what I actually need to do is, if the context is world: survival, then I want to take that word "survival" and somehow query what permissions the player WOULD have if they were currently under a context of server: survival, even if they are not currently under that context. I have no clue how to do that from anything I'm reading, and I'm not sure I understand what query options even are.
or how i actually use them to find a permission based on a theoretical context that may not be active, but definitely has permissions defined. like how my admin has server: survival defined as a context for like a hundred permissions but I can't query them because they show up wrong when I check the user's permissions and contexts
I need to get the displayname.{somewildcard} that they would have if they were under a server: survival context
example: I am a Moderator and i have the permission displayname.Moderator. I am using the "Moderator" part in messages sent as chat messages to proxied players, and I need to be able to obtain whatever is after the "displayname." and I need to be able to obtain this from the context it is defined under regardless of what server that user is on or what the active context is because the active context is never set correct thanks to the spigot servers being world contexts and our permissions being defined as server contexts. so I can't seem to obtain the displayname by any method i've tried with the API so far
compact spruce
well I figured it out mostly, but I'm just trying to figure out how to get the right display name because now i get all the displaynames for all groups inherited from
lol
compact spruce
LuckPerms api = LuckPermsProvider.get();
User user = api.getPlayerAdapter(ProxiedPlayer.class).getUser((ProxiedPlayer) sender);
String server = null;
// Loop through the active contexts to find the value for the key "world" if possible
for (Context ctx: api.getPlayerAdapter(ProxiedPlayer.class).getContext((ProxiedPlayer)sender)) {
if (ctx.getKey().equals("world")) {
server = ctx.getValue();
break;
}
}
// If world context is active
if (server != null) {
QueryOptions opts = QueryOptions.contextual(ImmutableContextSet.of("server", server));
CachedPermissionData data = user.getCachedData().getPermissionData(opts);
// Display all the permissions for key "server" with a value matching the "world" value
for (Map.Entry<String, Boolean> entry: data.getPermissionMap().entrySet()) {
sender.sendMessage(new TextComponent(entry.getKey() + ": " + entry.getValue()));
}
}
so I get the active context world: whatever and query permissions for server: whatever, but is there anyway to only get the permissions at the Moderator level? for example, right now I get displayname.B+, displayname.guest, displayname.B-, displayname.Moderator. I would like to only get the permissions at the highest level I guess, so i need only displayname.Moderator. Is this possible?
I tried using Flag.RESOLVE_INHERITANCE but that didn't do what I expected
sorry for text wall
high tiger
Say for example you wanted to give Bungee LiteBans' perms while you were in the ...
I'm the admin @compact spruce mentioned. From what I can understand, that setup would not make sense. What's the point of doing a server: context if it's always going to be server: bungee? I have a BungeeCord setup with 3 servers: lobby, survival, creative. To give players specific permissions on the survival server, I add the server: survival context to the permissions. This works perfectly. Is this not the correct way to do it?
compact spruce
the only reason it can possibly work perfectly as I can see it is that Essentials must have some workaround because according to the developer, what you have setup should not work as there does not seem to be a way to programmatically obtain the information that Essentials must somehow be obtaining
or I'm unaware of how to obtain it
nocturne elbow
Idk man I didn't design this, but again:
Everywhere, "server" refers to the specific LP instance (where LP is running), on the survival server it'll always be "survival", on bungee it'll always be "bungee". The "world" context however refers to "where the player is in", in Bukkit that is the actual world and on bungee that is the server name they are in
high tiger
the only reason it can possibly work perfectly as I can see it is that Essential...
It's not just Essentials; the permissions work perfectly with that setup for every plugin.
compact spruce
because when I obtain the active contexts using the API, i do not get the correct permissions
oh, I thought you were the developer lol my bad
nocturne elbow
Lol no
high tiger
Maybe it's because Essentials and all our other plugin permissions are being checked on the local spigot server.
nocturne elbow
Exactly!!
compact spruce
it always shows me the context of world: survival when it should be server:survival
yeah probably.
so it seems like my solution is gonna have to be the one I originally had which was to send the permissions from the spigot servers to the bungee server with plugin messaging or something
nocturne elbow
Just get the ProxiedPlayer server name and put that as server context for the QueryOptions
nocturne elbow
Well yes no shit, that's how inheritances work
compact spruce
I don't need 10 displaynames, i need Moderator
nocturne elbow
Transitivity exists
compact spruce
ok, but that's not the point. the context is world: survival
high tiger
From my (maybe incorrect) understanding, contexts are supposed to be used like this:
NO BUNGEE:
-world
-world_nether
-world_the_end```For this setup, I should add the context `world: world_the_end` to any permissions I want the player to have in The End.
BUNGEE:
```2 servers, 1 world each:
-creative (server name)
-world (world name)
survival (server name)
-world (world name)```For this setup, I should add the context `server: survival` to any permissions I want the player to have on the Survival server.Maybe it's not correct, but it works. :/
If you're supposed to use world: <servername> then how do you specify a world context for that server?
nocturne elbow
Thing is
There are two separate, totally independent and unrelated "levels" of perm checks, the permission checks occurring on server level (EssentialsX, vanilla commands, Bukkit commands, WorldEdit, etc), for those the world context is the actual world you are in (end, nether, overworld) and the server context refers, again, to the specific LP instance based on the setting in config
And then there's bungee perm checks (LiteBans/AdvancedBans, bungee commands, etc), for those, the world context is which sub-server you are in, and the server context refers to, yet again, the running LP instance based on the setting in config
Basically:
Server context refers to what LP and where the permissions are being checked
World context refers to where the player is in, regardless of where LP is
There is an open issue to change that, let me find it rq
As for your actual displayname issue, you are getting all perms because permissions and inheritances are transitive, and since the nodes' keys themselves are different, you're gonna get all of them. If I'm not mistaken they should be sorted by how inheritances are resolved, so the first one in the resulting collection should be the one of the "closest" group (presumably direct parent group)
compact spruce
if they're sorted and that the defined behaviour then problem solved lol
i just take the first displayname i find
lol
perfect
nocturne elbow
I'd assume you're using the PermissionHolder#resolveInheritedNodes(QueryOptions) method?
compact spruce
// If world context is active
if (server != null) {
QueryOptions opts = QueryOptions.contextual(ImmutableContextSet.of("server", server), new HashSet<Flag>() {
{
addAll(Arrays.asList(Flag.values()));
}
});
CachedPermissionData data = user.getCachedData().getPermissionData(opts);
// Display all the permissions for key "server" with a value matching the "world" value
for (Map.Entry<String, Boolean> entry: data.getPermissionMap().entrySet()) {
sender.sendMessage(new TextComponent(entry.getKey() + ": " + entry.getValue()));
}
}
when I added only the RESOLVE_INHERITANCE flag, it gave me only the bungeecord.whatever permissions
or possibly none, i can't remember
but when i use either all the Flags or none of the Flags i get the full permissions list for server: <servername>
<servername> being a value i obtained from the world context that is currently active
I'm doing that specifically because @high tiger has the permissions configured with the server context not the world context
so with the code there, I get a list of all the correct permissions but like i said, multiple display names
and I know that I am part of the moderator group, so i inherit all those other displaynames, but i just need the Moderator one. if it's at the top, then i can just loop through the results and find the first occurence of displayname
nocturne elbow
I'm not sure how the CachedPermissionData is backed, if it's backed by a regular hash map, then it isn't sorted, but in that case you should use either PermissionHolder#resolveInheritedNodes(QueryOptions) or PermissionHolder#resolveInheritedNodes(NodeType, QueryOptions) since those are sorted according to the platform's inheritance rules (a.k.a config)

You can pass any queryOptions
And embed any set of contexts there
I mean with vault you can only get the prefix of the user’s current context
compact spruce
yes but it works correctly with the way our permissions are defined using server instead of world
whereas with luckperms API it does not
so it's either redefine all our contexts as world or find a programmatic solution
because when i get the context it shows world: survival
crystal sonnet
yes but it works correctly with the way our permissions are defined using server...
Are you talking about the bungee?
compact spruce
yes
crystal sonnet
Yeah. Of course you can do it programmatically

crystal sonnet
gives the highest priority prefix for the current context?
Not quite. It returns what’s calculated to be the prefix after taking the stacking settings into account
But by default that means the highest prefix
But since you’re working with the bungee why are you even bringing up vault?
compact spruce
because I couldn't figure out how to do what i needed with bungee
but i figured out how to do it with vault at the spigot level
at which point i would send the information to bungee using plugin messaging
but if i can do it in luckperms in bungee that is preferable
crystal sonnet
I mean why wouldn’t you be able to?
compact spruce
it's a big project, which file might I look in?
crystal sonnet
Look for the LuckPerms5Hook
Hope that helps 🙂
Struggled a fair bit to get it working
compact spruce
found it. So, if I'm understanding this right, you get the QueryOptions from the ContextManager and use that to create a copy of the original context, then foreach WORLD_KEY you add a corresponding SERVER_KEY containing the world value to the new context which you build into a new QueryOptions. Then you use that new QueryOptions to get new meta data
then you can get the suffix from that
or prefix
crystal sonnet
Exactly
compact spruce
I get the gist of it, I don't fully understand what you're doing with streams there

Is there a way to prevent the inheritance node getting saved to storage? My idea is to only have the inheritance stored in cache so as soon as the player switches the server, disconnects or anything like that it gets erased
crystal sonnet
@silver sleet use transient nodes
There's a transient storage map
Like the nodes are the same, they just don't persist because you save them in a different place

Do you know about Luckperms api? because I will have this in my scoreboard when a player shows his group on the scoreboard that I have set with a prefix I do not know how to do it does anyone know?
long shale
so you are coding a scoreboard plugin?
Yes

I'm using Vault to access player prefixes/suffixes for when I'm displaying their formatted names in my plugin, it works great. But when a users prefix/suffixes changes for any reason I would like to know that so that I can update the formatted name(My plugin is creating holographic displays with formatted names). It looks like Vault doesn't have events to notify when that happens and I wouldn't like to hardcode my plugin against LuckPerms since Vault is supposed to be the abstraction layer here...
long shale
if so, what have you tried?
I haven't tried anything yet, I ask because the api is so heavy. I just want that the group in the player is displayed so the prefix with color of the group name stops

If you inherit many different values for a certain meta key, by default (https://github.com/lucko/LuckPerms/blob/0a99a9618835cb2b6b8a828fc61b4b4412e7673a/bukkit/src/main/resources/config.yml#L439-L453) the one from the group with highest weight is picked
queen nacelle
hmm
nocturne elbow
The cached meta data is the holder's meta data after resolving inheritances
So you should be able to grab it from there just fine
nocturne elbow
and i just want the value with the highes weight.
seems totally reasonable and sounds like the default behavior suffices your needs
queen nacelle
the ids are not orderd from lowest to highest :c
nocturne elbow
btw what does getMetaData().getMetaValue("discord") give you?

I don't see what the issue is, all this seems like the correct behavior
You can give a group its weight upon creation
/lp creategroup <name> [<weight>] [<displayname>]
queen nacelle
so the meta keys are orderd from weight

the first is confusing...
nocturne elbow
I don't see the issue
queen nacelle
I would first load the default group...
nocturne elbow
What you want is already default behavior, and when creating a new group you have to specify a weight if you want it to take over

Of course it doesn't. /s

It kind of depends what is it you're looking at specifically, but it is very similar (sometimes it isn't lol)

In any case you have to do is specify an expiry time when building the node

I'm promoting a user on the bungeecord-side via the API (via a bungeecord plugin command). However, it seems that this information is not fully synced to all spigot servers, because of some weird behaviour with Multiverse and Worldguard.. Can i trigger an immediate sync after promoting the player?

LuckPerms#getMessagingService gives you an Optional<MessagingService> (it's an Optional because it can be disabled)

LuckPerms has a problem, it currently has many vulnerabilities and some users take advantage of this to hack into servers, for example to give themselves permissions as members and have this same plugin give them such permissions

- How is that related to the LP dev API?
- You'd need to provide some details on what is it exactly that's going on with that, as far as I know there are no known vulnerabilities

This has been brought up many times and always boils down to backend server security

Can anyone help me understand why a simple hasPermission check as well as registering a Command with Command(String name, String permission, String... aliases) fails EVERY time in a BungeeCord plugin? I have luckperms set up both on my spigot server and bungee server
both servers are connected to the same sql database
i have server: bungee in the bungee config.yml and server: lobby in the spigot server's config.yml. pluginmsg for messaging
and if i create a custom bungeecommand and set a permission, then give my player that permission in the lp editor, with the correct context, it still says I don't have permission for the command
and it's red when i type the command, like it doesn't exist. If i change permission to null in the Command constructor, I can run it, but with permissions I cannot
I must be missing something...do the permissions not sync to the CommandSender that has the permission or do I have to cast them to ProxiedPlayer or what? I've been trying to figure this out for awhile
turbid solar
Did you sync your permissions?
obtuse jolt
messaging should be sql btw
also are you refering to a bungeecord plugin you are making, or every single bungee plugin you tried to install in your server network
compact spruce
I've tried setting messaging to both sql and pluginmsg but I can try again
i'm referring to a bungeecord plugin I'm making
how do I sync permissions?
I tried /lp sync that didn't do it
turbid solar
screenshot /lp info and /lpb info
turbid solar
Then that's likely the problem ;d
compact spruce
but how can that be
it literally is set to MySQL in my config.yml
wait is that from the spigot server?
that's the spigot command isn't it
shit
compact spruce
lmao now I get it. i copied spigot servers and started using lobby which I hadn't configured
i'm dumb lol
hm, storage method is set to sql. probably should say MySQL
that would probably make it fall back on h2
turbid solar
yep
compact spruce
that is a silly mistake
permissions still aren't working though, so
i'll have to try sql for messenger service see if that works
well it seems to work now as long as I don't set a context for the permission
setting context server=lobby makes it fail
even though I'm on lobby
maybe world=lobby
turbid solar
Ye
context system with bungeecord servers is a bit weird
so server=bungee would mean on the bungee server itself and world=lobby would mean the lobby server
iirc
compact spruce
beautiful. thanks for your help man, it's working now
yeah it's weird, i figured that out about the world/server thing but on our production server all the contexts are set as server and it still works for some reason. but not on my test server

nocturne elbow
Do you know the group the prefix is in / do you know which group holds the prefix?
grand hearth

nocturne elbow
That uuh.. doesn't answer the question
You want to get the weight for a certain prefix
That prefix is being held by a certain group
Do you know which group?
grand hearth
Well, each group will only have one prefix, and I want to get the weight of it for each of them
So yes, I have an arraylist of every prefix, and I need to get the weight for them and make them into a hashmap or something
nocturne elbow
Do you have an array of group names or prefix values?
grand hearth
both
nocturne elbow
Well for each group you can do getNodes(NodeType.PREFIX), that will give you a collection of the holder's own nodes, not inherited ones

Fefo, is there a difference in using the serviceprovider or just doing LuckPermsProvider.get()
nocturne elbow
Fefo, is there a difference in using the serviceprovider or just doing LuckPerms...
Well ideally the instance would be the same, but things like /reload beg to differ
Using the service provider also gives you the possibility of not crashing your plugin because something is missing, since it would return null instead of throwing ClassDefNotFoundErrorWhatever
So the service provider is 100% the way to go if you soft-depend on it

we have a system which syncs configs across servers, but i'm trying to avoid doing text replacement in it

Well, you can't really change the setting without replacing it in the config file. You could potentially do it with reflection but you are on your own there, specially because in Java 15+ final actually means something and you can't use any reflection to change final fields (afaik)
So no, there is no API for that

I use Vault to get offlineplayers prefix and suffix during the startup of my plugin but I'm having problems where sometimes I don't get a prefix/suffix for a offlineplayer and I believe it's because Luckperms have not had the chance to set everything up...

Hello!
I'm trying to make a basic plugin that gets the luckperms prefix, and displays below the users name using scoreboards. I added the luckperms api, and added the listener as well. This is my main class:
public class Main extends JavaPlugin implements Listener {
@Override
public void onEnable() {
RegisteredServiceProvider<LuckPerms> provider = Bukkit.getServicesManager().getRegistration(LuckPerms.class);
if (provider != null) {
LuckPerms api = provider.getProvider();
}
String prefix = user.getCachedData().getMetaData().getPrefix();
User user = luckPerms.getUserManager().getUser(uuid);
}
@Override
public void onDisable() {
getLogger().info(ChatColor.RED + "Goodbye!");
}
@EventHandler
public void join(PlayerJoinEvent event) {
Player player = event.getPlayer();
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getNewScoreboard();
Objective objective = board.registerNewObjective("rank", "dummy");
objective.setDisplaySlot(DisplaySlot.BELOW_NAME);
objective.setDisplayName(prefix);
for(Player online : Bukkit.getOnlinePlayers()){
Score score = objective.getScore(online);
online.setScoreboard(board);
}
}
}

you'd probably want to move the prefix & user variable in the playerjoinevent
then move LuckPerms api above the onEnable() so that you can access it from the anywhere in the class
then do luckPerms.getUserManager().getUser(player.getUniqueId() or whatever the correct method is from player

are you using your own custom leaderboard or something like holographic displays API?
mossy surge
are you using your own custom leaderboard or something like holographic displays...
Yes its that Api

well then refresh the placeholders using the {medium}
tag
at the end of the placeholder
this will refresh the placeholders
even after initial load

Hey there, I am using luckperms 5.2.76 with my plugin (I was using previous version of 5.2 aswell) and it used to allow me to update my users player group but for some reason, it stopped working! In the PlayerJoinEvent I have this System.out.println(Main.lp.getUserManager().getUser("username").setPrimaryGroup("groupname")); and it returns "FAIL" .. It was working previously and then suddenly stopped.. I am stumped as to why, please give me some advice 😄
however getPrimaryGroup() succeedes! The group exists in luckperms, and if my parent group is already set to it, luckperms returns "FAIL_ALREADY_HAS"
nocturne elbow
yeah..... that sounds totally normal behavior?
If your primary group is that group already, then it will fail because you already have it as there is nothing to change
rain hemlock
No, What I am saying, is that when it isn't already my primary, it Fails
it fails to set the primary
yet it is able to get the primary
in the case where it is the primary, it acts as it should
nocturne elbow
Well that's because setPrimaryGroup is likely not what you want, the primary group is, by default, calculated and it's the parent group with highest weight and you can't change that unless you change a setting in LP config which no owner should change lol
rain hemlock
setPrimaryGroup changes the users parent group no?
nocturne elbow
No
nocturne elbow
!cookbook there is an example that replicates the parent set command which sounds that is what you want to do
frank driftBOT
rain hemlock
thank you, this is helpful! Strangely, it used to work by setting the primary group!
where do I download releases of this api?
nocturne elbow
!api first link
frank driftBOT
LuckPerms wiki
nocturne elbow
It's an example plugin, there is no built jar out there lol
rain hemlock
ahh I see, thank you
nocturne elbow
The idea is that you check how it uses the LP API
tired pond
was gonna say that fefo :(
nocturne elbow
You can download it as a zip tho under "Code"
rain hemlock
makes sense, just wondering why these features (eg setParentGroup()) isn't a function in the plugin?
nocturne elbow
Because a PermissionHolder (users or groups) can have many parent groups, not only one
And there are many variables taken into account too
rain hemlock
I mean, could they not just copy whats in the onCommand of the ingame user <> parent set command
main dagger
the command is a lot more complicated than you think
nocturne elbow
rain hemlock
the command is a lot more complicated than you think
but they could just turn it into a function as part of the api
rain hemlock
xD
nocturne elbow
Malleable
rain hemlock
so to set parent group?
nocturne elbow
You've got to be kidding
nocturne elbow

I'm writing a command that will remove all users from a list of groups, and clear all personal permissions
User#getNodes says it's fast, but I'm assuming modifying it won't modify the user's permission nodes
Or maybe it's not modifiable at all
What's the most efficient way to do this?
nocturne elbow
oh hello redempt
wheat elm
o/
nocturne elbow
Yeah getNodes returns an immutable collection (I think 
), if you want to modify the holder's data, use PermissionHolder#getData instead
wheat elm
Ok
nocturne elbow
!cookbook you can see a few examples in here on how to modify a user's nodes and uuh other examples
frank driftBOT
wheat elm
for (OfflinePlayer player : Bukkit.getOfflinePlayers()) {
User user = luckPerms.getUserManager().getUser(player.getUniqueId());
NodeMap data = user.data();
user.getNodes().forEach(data::remove);
luckPerms.getUserManager().saveUser(user);
}```This should do it, right?
But I'm assuming this will also clear all groups because groups are technically nodes?
nocturne elbow
you just want to clear all nodes the user has?
a node is also parent group, meta key/values, prefixes, suffixes etc etc etc
wheat elm
Yeah, but I only want to clear specific groups
Ah, alright
user.getNodes().stream().filter(n -> n.getType() == NodeType.PERMISSION).forEach(data::remove);
This, then?
nocturne elbow
You can getNodes(NodeType.PERMISSION) 👀
also, UserManager#getUser will return null if the player is offline and judging by what it seems you want to do, you should use UserManager#modifyUser(UUID, Consumer<User>), it loads the user, runs the action and saves the data, all async
wheat elm
Ah, cool
So, something like this
luckPerms.getUserManager().modifyUser(player.getUniqueId(), u -> {
NodeMap map = u.data();
u.getNodes(NodeType.PERMISSION).forEach(map::remove);
});```luckPerms.getUserManager().modifyUser(player.getUniqueId(), u -> u.data().clear(n -> n.getType() == NodeType.PERMISSION));
nocturne elbow
what?? lol, you just end up with u.data().clear(NodeType.PERMISSION.predicate())
wheat elm
Yeah
nocturne elbow
or if you're fancy NodeType.PERMISSION::matches
wheat elm
Having a preciate() method seems so unnecessary
nocturne elbow
come on Redempt I know you're better than this hah
nocturne elbow
INHERITANCE
wheat elm
Ah cool
nocturne elbow
afaik PERMISSION are wildcard permissions, specific permissions and shorthand permissions
wheat elm
I'm assuming I'd get the group name with Node#getKey
nocturne elbow
regex have their own type
mnop
InheritanceNode#getGroup I think?
getGroupName
wheat elm
Ah cool
nocturne elbow
getKey will return the whole string representing the node (group.<group> if it's a parent group)
wheat elm
Yeah that's what I was figuring
That's probably simpler honestly
luckPerms.getUserManager().modifyUser(player.getUniqueId(), u -> {
u.data().clear(NodeType.PERMISSION.predicate());
u.data().clear(NodeType.INHERITANCE.predicate().and(n ->
toRemove.contains(((InheritanceNode) n).getGroupName())));
});``` for (OfflinePlayer player : Bukkit.getOfflinePlayers()) {
luckPerms.getUserManager().modifyUser(player.getUniqueId(), u -> {
u.data().clear(NodeType.PERMISSION.predicate());
u.data().clear(NodeType.INHERITANCE.predicate().and(n -> toRemove.contains(n.getKey())));
}```I think this is the second time ever I see someone using Predicate#and(Predicate) lol
instead of &&
wheat elm
¯_(ツ)_/¯
nocturne elbow
is neat ngl
wheat elm
I'll just stick with the first way because it's less compact but probably better practice
nocturne elbow
I presume toRemove is a set/list containing the group names to remove?
nocturne elbow
wheat elm
LuckPerms API is strange but I like it
nocturne elbow
strange how
wheat elm
NodeType.PERMISSION.predicate()
nocturne elbow
Well it returns a Predicate<Node> that checks if the node type matches it
wheat elm
Yeah
nocturne elbow
Could have done ::matches too ¯_(ツ)_/¯
wheat elm
It's so weird
nocturne elbow
Could have done ::matches too ¯\_(ツ)_/¯
if I'm not mistaken #predicate() does that
wheat elm
It doesn't seem to have worked
Groups and personal permissions of players seem to be unmodified
wheat elm
It only prints for online players .-.
Guess the user data was reset
So LuckPerms has stuff for offline players that bukkit doesn't
nocturne elbow
Doesn't getOfflinePlayers return the ones in usercache.json or whatever?
wheat elm
Yeah
nocturne elbow
So LuckPerms has stuff for offline players that bukkit doesn't
and I think you can get all UUIDs LP knows of since it keeps a cache
uuuh
wheat elm
Assuming I can do luckPerms.getUserManager().getUniqueUsers()?
nocturne elbow
yeah that must be it
if it returns a completablefuture<collection<uuid>> then yeah
wheat elm
luckPerms.getUserManager().getUniqueUsers().thenAccept(s -> s.forEach(id -> {
luckPerms.getUserManager().modifyUser(id, u -> {
u.data().clear(NodeType.PERMISSION.predicate());
u.data().clear(NodeType.INHERITANCE.predicate().and(n ->
toRemove.contains(((InheritanceNode) n).getGroupName())));
});
}));```or.. something similar

what an odd api
What’s odd about it?
delicate briar
Could not load 'plugins/Myplugin.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError: net/luckperms/api/LuckPermsProvider
...
Anyone can is able to tell me what I need to do with this error, It like 4 hours I am trying to do tests on tests
turbid solar
Are you (soft)depending on LP?
Make sure you're not statically getting the provider & that you dont shade it in
delicate briar
Are you (soft)depending on LP?
What I need to soft depend?
turbid solar
LuckPerms
delicate briar
Now it print another error
The LuckPerms API is not loaded.
But I imported with maven dependency
turbid solar
!paste full error
frank driftBOT
delicate briar
turbid solar
paste your FixEssentials class
delicate briar
turbid solar
put LuckPermsProvider.get() under onEnable()
delicate briar
Same error
turbid solar
you didn't do what I said
move LuckPerms luckPerms = LuckPermsProvider.get(); in onEnable()
if I wasn't clear sorry
delicate briar
If I move the other things can't compile
turbid solar
then at the top do LuckPerms luckPerms; then in onEnable() do luckPerms = LuckPermsProvider.get();
delicate briar
Thank you for the patience and for the helping, this works now

I'm looking for which event to use for checking when a user's primary group is updated. Closest one I could find is UserDataRecalculateEvent but it exhibits some unexpected behavior. I'm extremely close to just making the event myself and submitting a PR
And the track events do nothing in my use case
nocturne elbow
NodeAddEvent
Probs, that's most likely always what people really want lol
Check that the target is a User and the node is of type INHERITANCE
That would be when a new parent group is added (which may or may not be the primary group, remember that holders can have several parent groups and even then the newly added one may not be the primary group according to settings and weights setup)
uneven marten
I don't know if this is LP's fault or not, but now it's doing this for all online players every 10 seconds or so. Otherwise, It's doing exactly what I need
nocturne elbow
I have no clue what you're talking about but (if it is what I think it is) data recalculation happens somewhat frequently, mostly when contexts update

Hi is there a way to allow only to do lp commands if a player has a certain ip?
turbid solar
No, unless you want to code a plugin that might do that?*
obtuse jolt
yea but abit weird that you need to do that tho
nocturne elbow
Someone has hacked my server and is able to spoof my admins account to get permissions and we can't fix that. So we only want to authorize commands by ip. My server is in prenium
