Maybe I'm biased because I'm a C# dev, but I'm not a big fan of Optional<T>. Then again, Java doesn't have ?., so null checks have to be done manually (or through the Optional).
#luckperms-api
hollow grotto
?. only performs the operation on the right if the result of the value on the left is not null.
// This statement assigns someValue to the value returned by GetSomeBool(). If myPossiblyNullInstance is null, then the ?? operator kicks in.
// The ?? operator returns the value of the left side unless it is null; otherwise, the right side.
bool someValue = myPossiblyNullInstance?.GetSomeBool() ?? false;
crystal sonnet
That’s essentially what Optional is for
@nocturne elbow make sure your plugin depends on LP/loads after it

Alright so my question is not completely related to LP but in a way it still is
I need to send a message when the Join event is called but that message needs to contain the players name and their prefix/suffix so it needs to be loaded after luck perms have assigned them their prefix/suffix
I’ve tested my plugin and the message is sent with only their name and no prefix but the leave message does contain the prefix. So I believe it’s just not loaded when the message is sent on join

I tried Monitor, high and low

So I've added LuckPerms API to my plugin using maven, and did LuckPermsApi api = LuckPerms.getApi();. Everything compiles but when I start the server with the plugin, it says that API is not loaded (I do have LuckPerms installed on the server). What am I doing wrong?
crystal sonnet
@obtuse rapids make sure that you're not shading the API in and that your plugin loads after
obtuse rapids
I added softdepend: [LuckPerms], it didn't work, depend: [LuckPerms] didn't work either
And all I'm doing with the API right now is
LuckPermsApi api = LuckPerms.getApi();
and
api.getUser(event.getPlayer().getName()).getPrimaryGroup()
crystal sonnet
@obtuse rapids How are you building your plugin?
obtuse rapids
I am not quite sure if I understood the question correctly, but here are the building dependencies
and here's a screenshot of the artifacts tab in project structure settings
gilded bane
What are you using to build the jar? Maven or Gradle? The "build" button in your IDE?
gilded bane
It looks like Maven
obtuse rapids
it is maven
jaunty pecan
where are you calling getApi from?
obtuse rapids
main class
jaunty pecan
where abouts in the main class
obtuse rapids
jaunty pecan
move it to inside of onEnable
the reason it's throwing that exception is because the main classes of all plugins are initialised before the process of enabling them starts
so the constructor of your plugin (which is effectively what you're initialising in) is called before LP enables
obtuse rapids
oh I see

Thanks, it finally works

Hey, how i should do to get number of home count with LP api ? its metaData ? Thanks !
String homecountS = metaData.getMeta().get("home-count");
int homecount = Integer.valueOf(homecountS);
int totalhome = homecount + Integer.valueOf(args[1]);
metaData.getMeta().replace("home-count",String.valueOf(totalhome));```
Isnt correct ? thats return me an error :p
```java.lang.RuntimeException: java.lang.UnsupportedOperationException``` i got this 🤔@obtuse rapids late reply but i think the method you are looking for is getFriendlyName()
crystal sonnet
@polar cargo setting meta values works differently
There should be examples on the wiki
polar cargo
i didnt find the example <w<
polar cargo
already tried it i think
{
String key = entry.getKey();
if (key.equalsIgnoreCase("home-count")){
//String value = entry.getValue();
entry.setValue(String.valueOf(totalhome));
}
}```that too
polar cargo
yeah thatss a bit weird for me, i dont use this api often^^
polar cargo
I'm not sure to understand, i created a class that have LP Event
public class LuckPermEvent {
MinecraftServer server = FMLCommonHandler.instance().getMinecraftServerInstance().getServer();
public void onUserPromote(UserTrackEvent event)
{
//
}
}```
How i can register it ?
```Java
@Mod.EventHandler
public void init(FMLInitializationEvent event) {
LuckPermsApi api = LuckPerms.getApi();
api.getEventBus().subscribe(UserTrackEvent.class, ?);
}
Not sure to understand, its not like forge/sponge <w<

marble shore
How'd you set the prefix of a player programatically?
cunning halo
use essenshalsx
neat jackal
Why? He wants to know how to set a prefix of a user using the LuckPerms API. What has EssentialsX have to do with that?
marble shore
I've never really used LP before (At least not the API), and there seems to be no documentation at first glance. Maybe documentation could be added on how to edit prefixes and suffixes on the JavaDoc for getPrefixes on MetaData. Still leaves me wondering how to actually set a prefix with a specific weight on a player
gilded bane
If there's no obvious method, you could construct the node yourself and add it
API equivalent of giving the player/group prefix.<weight>.<prefix>: true
I don't actually know of any "add prefix" method in the API
marble shore
Alright
I looked at the command but sadly that depends on common which is not included in api

@marble shore the wiki has plenty of expamples

ProviderRegistration<LuckPermsApi> provider =
Sponge.getServiceManager().getRegistration(LuckPermsApi.class).orElseThrow(NullPointerException::new);
LuckPermsApi api = provider.getProvider();
User user = api.getUser(player.getUniqueId());
if (user == null) {
player.sendMessage(Text.of(TextColors.RED, "LuckPerms profile not found."));
return;
}
DataMutateResult result = user.setPermission(api.getNodeFactory().makePrefixNode(1000, text).setValue(true).build());
System.out.println(result);``` results in "SUCCESS"But the prefix was not set
crystal sonnet
@marble shore you need to save the changes
And also you can just pass the player instance. No need to get the UUID
marble shore
Also passing Player does not work with Sponge on API version 4.4
crystal sonnet
Really? That’s a bug then
marble shore
Probably not, as it's a shared library
crystal sonnet
I mean did you try?
marble shore
Yeah, Intellij does not recognize it as valid
crystal sonnet
Hm. There should be a method that accepts an object
marble shore
I see
crystal sonnet
Which is used to accept native player instances
marble shore
crystal sonnet
Would be very surprised if that was gone
marble shore
No such method in getUserManager either
marble shore
So getting an user returns a mutable version that is not linked to the storage
crystal sonnet
In essence

@shadow fjord I asked how to do it with the API, not the editor

@nocturne elbow the error is being thrown in your onEnable. Not in the command handler

But I have a question with something else now

Guys, I'm having issues with the setPrimary group within the API.
I've checked the API but it doesn't seem to work.
Could you guys give an example on how it would work, this would be amazing! 😃

Can you send the part of the code you use
?
Also, if aanyone can help me for event LP that can be cool xD
rapid osprey
@polar cargo we used this
before we used the api but it doesnt work.
also that does apply as quick as we hope
rapid osprey
Anyone?
polar cargo
if you use command, use switchprimarygroup ?
polar cargo
i mean, what you want to do ?
rapid osprey
i want to remove the group Z
and then add the group A
I know EzRanksPro does it but how?
polar cargo
I dont use bukkit plugin so i cant says for it
if you have only one group, you can do parent set A ?
rapid osprey
im doing Java...
rapid osprey
Yes but I wan't to switch to the API but it doesn't work..
polar cargo
I want the error or the part of the code you tried to use
for group you have something like user.setPrimayGroup(string)
polar cargo
Yeah, but i just started to use LP as API
crystal sonnet
The primary group has nothing to do with the actual groups
polar cargo
i just successfully use Event, and for setPrimary group i didnt test but pretty sure it work
rapid osprey
Oh hello.
polar cargo
but you need to add the group first
crystal sonnet
With the default settings it can’t even be set
polar cargo
i think
crystal sonnet
As it’s calculated automatically
You need to assign the groups
Or the permission for it
There are examples on the wiki for that
rapid osprey
Brain, is there not anyway to add the group to the user without it lagging?
EzRanksPro does it and I don't know how.
crystal sonnet
Of course it doesn’t lag
As I said. Check the wiki
There are plenty of examples
rapid osprey
Stone, the thing is, I have.
It takes a while and it can glitch EzRanksPro.
crystal sonnet
If you’re using the API and it takes a while, then you’re doing it wrong. And if it glitches out ERP, then that’s not on LP
rapid osprey
No we're now using the commands.
Due to the API not working for us.
If you could give us an example, this would be amazing 😃

I'm not working quite much with Plugins, but I think this could work:
public void onEnable() {

Did you mark LuckPerms as a dependency in your plugin.yml?
soft edge
does LP fully support SubjectCollections besides users and groups? I'm wanting a separate collection to store a town's permission groups in

I can create alternative collections and subjects through the sponge permissions service, but it won't let me add the subjects as a user's parent

How do you get a user's group?
String group = plugin.lapi.getUser(p.getName()).getPrimaryGroup();
that's sending me a nullpointexception
long moon
NPEs are caused by the assumption that something isn't null
We can't really say from a singular line of code, pretty much anything could be null there, but methods like getUser should generally always be checked for a null return
crystal sonnet
My guess that either plugin or plugin.lapi is null
The rest shouldn’t be null ever
midnight wren
It's the getPrimaryGroup() that's causing the error
The plugin and lapi are variables
lapi is for LuckPermsAPI
and plugin is the instance to my main class where I have a few other functions stored that I use
Do I have to check to make sure it isn't null?
midnight wren
Like to make sure the player actually has a group?

How do I change the "permissions message", (ex. you dont have the permission blah blah..... missing -mutliverse.tp to you dont have that permission.)?

that would be up to the plugin that throws that error
proud crypt
luckperms doesn't tell users the permissions they are lacking.
nocturne elbow
oh it does not
proud crypt
unless you are using verbose mode.
nocturne elbow
dont think so
neat jackal
There is a normal vanilla message in spigot.yml or the plugin specified one
commands:
some-command:
permission-message: No perm
permission: some.perm
This can be used in plugin.yml or a simply
if(Player.hasPermissiin("some.perm")) {
// do stuff
} else {
Player.sendMessage("No perm");
}
It’s always the plugin itself that sends the lacking permissions message
I’ve yet to see a single exception
neat jackal
You may be able to set a no-permission message in the config of the plugin, but not all plugins have to support this
nocturne elbow
ah okay, well thanks for the fast support!

Very true
Figure out how the console works, then play around with things like basic math or maybe random numbers if you're feeling up for a challenge. But game design is not the place to start.
We run into people all the time in a general C# community I'm in that have no coding experience at all but decide that developing a game in Unity is definitely the best way to learn how to code.

You say that, but I was that beginner once

I might sit down with Helper and come up with a plugin that lets people develop their own commands through a text file. Make it a bit more flexible than Bukkit's commands.yml (and x-plat). Probably just some sort of macro-like system which allows you to define commands, typed strongly named arguments, and a few method-like commands. I may format it something similar to how appveyor does their script files https://github.com/LuzFaltex/docs/blob/master/appveyor.yml
Unless you guys think that's not a good idea. ¯_(ツ)_/¯

Currently I'm using lpUser.hasPermission(permissionNode).asBoolean();

Hello, I'm writing my own permission manager and I'd like to use LuckPerms' API for this purpose, but for only adding permissions to players. Since LuckPerms doesn't work if the server is in offline mode I can't use the API either. So is there any way to use the API's permission manager functions in offline mode?
teal tartan
@vagrant rose lp works on offline mode servers but i don't think you can do that
vagrant rose
That's sad, but thanks for the reply.
crystal sonnet
@vagrant rose I don’t see a reason why you wouldn’t be able to do that in offline mode
vagrant rose
Because I can't join to the server if the plugin is loaded and if the plugin isn't loaded then my plugin can't use the API
crystal sonnet
Well if you’re using Craftbukkit, then offline mode doesn’t work
In fact that should be in the join message
It works fine with Spigot @vagrant rose
vagrant rose
I will give it a try, but I had some trouble with Spigot last time, this is why I still using CraftBukkit
crystal sonnet
And if there really wasn’t an error message telling you to use Spigot if you want to use offline mode, then I’d be quite surprised tbh
As that would mean you have a very old version of LP
vagrant rose
I got the message, but I just wanted to know that is it possible with CraftBukkit offline mode
vagrant rose
I switched to spigot and everything looks fine
crystal sonnet
Think about it
If there is a message explicitly telling you, you need x to be able to y, what on earth makes you think it’s possible to do it without it?
vagrant rose
Because the AsyncPlayerJoinEvent was the problem I tought that there is a way to ignore this and only use the working part. Now the permissions works with Spigot and LP but the command auto complete doesn't. What can I do to fix it? The player has the permission but the command is red when typing and auto complete doesn't show some command.

Possibly? I read 1.13 was supposed to have some big changes in how mods were supposed to attach so version upgrades would have less of an impact, though that was on Sponge's side. Idk what Bukkit is doing.
gilded bane
Sponge for 1.13 and 1.14 isn't even out yet, so you can't run LuckPerms on Sponge on those versions
From what I've heard, LP runs as-is on Bukkit/Spigot
hollow grotto
Ok that's true

Hey together 😃 I have a question: Is it possible to stop or pause the time from a temp permission?
Thanks for help 😃
opaque apex
Hi everyone, I have got a question: How can I set the user prefix with the api?
verbal terrace
Try:
Node prefix = api.getNodeFactory().makePrefixNode(100, "[Some Prefix]").build();
user.setPermission(prefix);
opaque apex
i'll try
and how can I check if the user has the prefix now?
cause I want to check if it works with my nick system
[16:17:38 INFO]: [LP] - Prefix: None
[16:17:38 INFO]: [LP] - Suffix: None
uhm
@verbal terrace ?
verbal terrace
Have you saved the user?
"api.getUserManager().saveUser(user);"
After add or remove somthing you must save the changes
verbal terrace
Ja spreche ich ^^
opaque apex
danke 😄
verbal terrace
Kein Problem. da muss man auch erstmal richtig durchblicken ^^
opaque apex
ja xD
verbal terrace
Can someone help me? How can i pause the time from a temp permission?
crystal sonnet
No real way
As the permission saves the end time
So my best idea would be to constantly push the end time back
Like once every second
@verbal terrace
teal tartan
Or once hour push it for hour 😉
crystal sonnet
Depends on how long the freeze will be
But in any case, you’ll need to push the end timestamp further
verbal terrace
Ok thank you 😃
grim echo
Heyy, I am using the API for changing a suffix.
But when a player logs off & on it disappears.
p.sendMessage(chatutils.format("&8[&4Supreme&8] &7Je hebt succesvol de tag " + tagname + " &7geselecteerd!"));
playerUser.clearMatching(n -> n.isSuffix() && n.getSuffix().getKey() == 50);
playerUser.setPermission(prefix);
api.getUserManager().saveUser(playerUser);
p.closeInventory();
This is what I got rn.
crystal sonnet
How are you getting the playerUser?
grim echo
LuckPermsApi api = LuckPerms.getApi();
User playerUser = api.getUser(p.getUniqueId());
That’s odd. What LP Version? @grim echo
grim echo
Its for 1.7
But I already found it. There is nothing wrong with the code.
The server is hosting the database in NA. So its to slow.
crystal sonnet
Ok
And well, that doesn’t answer the which LP question
Funnily enough I was gonna suggest to see if normal commands work
grim echo
4.3.39 bukkit legacy is the one we are using.
crystal sonnet
You really could update. That’s half a year old
dull rover
Quick question, so I handle permissions in my plugin via Vault. Some users are getting an issue with it running sync. Is there something I need to do special for luck perms to tell it to run async?
crystal sonnet
@grim echo well since the issue is a slow database, I’d say no
But there are several other improvements and fixes
@dull rover LuckPerms does everything async. But when you change something through the vault API while you’re in a sync context, it’ll block your current thread. As the Vault API demands that methods wait until doing the change is finished
That’s why you need to make the calls async.
runic bolt
Is there a list of groups obtainable? Trying to do a for loop with for (String g : lp.groups)
crystal sonnet
Pretty sure there’s a list
dull rover
Yeah I figured so I should be able to just run it via TaskChain async and have no issues.
runic bolt
It gives me an error when I created the set @teal tartan
teal tartan
Hm?
runic bolt
It wants me to remove the set in the ()
teal tartan
You can use set in for
runic bolt
When I’m doing List<Group> list = ArrayList<Group>(Set) wants me to remove the (set) and replace with ()
teal tartan
You can use Set in for loop you don't need that

Hey MrIvanPlays! Please don't tag staff members.

Then I think it's time you learn how to add a library to your project so your IDE has the source and Javadocs
I personally would recommend gradle

Though I've heard people saying maven is easier

In any case use maven then to include the library and make sure your IDE pulls sources and javadocs

Hey, how can I get all groups that are active on the server? Api.getGroupManager.getLoadedGroups doesn’t work...
crystal sonnet
What do you even mean by that?
crystal sonnet
So you want all groups?
runic bolt
yep
crystal sonnet
Did you check the other methods of group manager?
The Javadocs are typically pretty helpful
runic bolt
I checked...
teal tartan
I think you will have to load all groups first
crystal sonnet
Groups are loaded by default
And even if not, there’s a way to get all existing groups
runic bolt
Okay? may I get that way?
lime python
Is there a way to get all of a player's groups, in https://github.com/lucko/LuckPerms/blob/master/api/src/main/java/me/lucko/luckperms/api/User.java there is only get primary
gilded bane
From a quick glance, you could iterate over all groups then check which ones user inherits?
zenith linden
crystal sonnet
@zenith linden did you check the wiki? There are plenty of usage examples
bright tapir
Hi there.
I used to use Vault to interact with LuckPerms' API but I figured it's time to just fully integrate with LuckPerms (this is a private plugin so there's no worry about compatibility)
I used to use vaultChat.getPlayerPrefix(player) to get a players prefix. I took a peek at LuckPerms' API usage and I just wanted to doublecheck that this is the correct way to get a prefix.
main.getLuckPermsApi().getUserManager().getUser(player.getUniqueId()).getCachedData().getMetaData(Contexts.allowAll()).getMeta().getOrDefault("prefix", "ERROR")
bright tapir
Or should I just use main.getLuckPermsApi().getUserManager().getUser(player.getUniqueId()).getCachedData().getMetaData(Contexts.allowAll()).getPrefix()?
crystal sonnet
@bright tapir I’d recommend you read the code InsideIntel posted
And the wiki has good examples too
bright tapir
Isn't that basically what I'm doing but with more variables?
Or is there something I'm missing..
crystal sonnet
The major difference is that he gets the players contexts
Which means per server groups and and prefixes are considered correctly
lime python
anyone knwo how to use User Track Event api barely says anything
crystal sonnet
The Javadocs explain it fairly well iirc
lime python
Sorry thats what I meant, the docs dont show any examples or anything
bright tapir
Okay, hi there.
public static String getPlayerPrefix(Player player) {
Contexts contexts = luckPermsApi.getContextManager().getApplicableContexts(player);
return luckPermsApi.getUserManager().getUser(player.getUniqueId()).getCachedData().getMetaData(contexts).getPrefix();
}
I'm using this little snippet of code to get a player's prefix, but for some reason it's throwing a nullpointerexception.
IntelliJ seems to be saying that getCachedData could produce the nullpointerexception, so I'm wondering how to avoid this.
Do I have to load the user first?
Or check if the user is null and then getCachedData()?
crystal sonnet
If a method can return null, there really isn't a way to prevent that
Only thing you can do is error handling
Or checking if it returns null
Also you should get the user instance first, and use it in getApplicableContexts instead of the player
@bright tapir
bright tapir
Thanks for the ping, wasn't sure if anyone responded
getApplicableContexts takes in an Object so it might implicitly need to to take in a User and not a Player, or else it'll error?
That's probably why it wasn't saying anything was wrong.
@crystal sonnet is this looking a bit better:
public static String getPlayerPrefix(Player player) {
User user = luckPermsApi.getUserManager().getUser(player.getUniqueId());
Contexts contexts = luckPermsApi.getContextManager().getApplicableContexts(user);
return user.getCachedData().getMetaData(contexts).getPrefix();
}
Hey TehBrian! Please don't tag staff members.
bright tapir
Sorry ;/
crystal sonnet
I'm pretty sure it would've worked that way
But doing that is more efficient and safer
bright tapir
Okay I'll try that.
crystal sonnet
And your IDE can't do code analysis that deep
bright tapir
I'm going to bet it's going to work now, it probably just needed user passed in rather than player.
crystal sonnet
As I said, I think it would've worked either way
bright tapir
Hmm, here's to hoping.
Before it was just throwing NullPointerExceptions so I guess we'll see.
bright tapir
Throwing.
crystal sonnet
Ok. Then yeah
bright tapir
Like, I'd get an error in my console and my entire Event wouldn't work (it's for playerchat event.)
Said, exception NullPointerException occurred and gave me a stack trace.
crystal sonnet
Yeah
bright tapir
Restarting server now, here's to hoping.
It's still not working.
It's giving a different exception now! Which is good!
public static String getPlayerPrefix(Player player) {
User user = luckPermsApi.getUserManager().getUser(player.getUniqueId());
Contexts contexts = luckPermsApi.getContextManager().getApplicableContexts(user);
return user.getCachedData().getMetaData(contexts).getPrefix();
}
``` using this code, I'm getting this stack trace:oh..
I think I need to use a player..
crystal sonnet
Which is line 19?
bright tapir
The line where I get contexts from.
And that's the line we just changed from player to user.
bright tapir
So it needs to be a player, but a player returns a nullpointerexception.
crystal sonnet
Where does it throw the NPE?
bright tapir
crystal sonnet
If you don't know, store the return value of each function in a variable
bright tapir
That's my chat event handler.
If I replace LuckPermsUtils.getPlayerPrefix(player) and the suffix variant aswell, to say, "Prefix" and "Suffix", it works fine.
Of course it literally shows up in chat as "Prefix" and "Suffix" but that just shows it's not a problem with that.
.. seems to just be inside the getPlayerPrefix/Suffix methods, but the methods are doing everything that the Usage in the Wiki seems to say..
Seems to say to give it a Player not a User so I suppose I'll put that back to player..
And then combining that with this..
it seems like I'm doing everything perfectly by the book
it just won't work
I'm going to take a further peek into getCachedData, that seems to be the best bet.
This is infuriating.
OK I've devised a little test, it's possible that we're getting a null user somehow.
It's
so the user isn't null??
crystal sonnet
Try using the debugger to step through the code to find out what throws null
Alternatively print out every return value of every method
bright tapir
I'm going to try that.
Alright first I'm trying this:
public static String getPlayerPrefix(Player player) {
User user = luckPermsApi.getUserManager().getUser(player.getUniqueId());
Contexts contexts = luckPermsApi.getContextManager().getApplicableContexts(player);
if (user == null) {
return "User was null.";
}
MetaData metaData = user.getCachedData().getMetaData(contexts);
return metaData.getPrefix();
}
Being used by this:
@EventHandler
public void onPlayerChat(AsyncPlayerChatEvent event) {
Player player = event.getPlayer();
if (player.hasPermission("tfcplugin.chatcolor")) {
event.setMessage(MiscUtils.color(event.getMessage()));
}
event.setFormat(MiscUtils.color(main.getConfig().getString("chat_format")
.replace("{prefix}", LuckPermsUtils.getPlayerPrefix(player))
.replace("{suffix}", LuckPermsUtils.getPlayerSuffix(player))));
}
I know that EventHandler works with regular strings.
Is it possible that getPrefix() is returning null?
Alright, using that, I'm getting this stacktrace:
I'm going to try with this event now:
@EventHandler
public void onPlayerChat(AsyncPlayerChatEvent event) {
Player player = event.getPlayer();
if (player.hasPermission("tfcplugin.chatcolor")) {
event.setMessage(MiscUtils.color(event.getMessage()));
}
event.setFormat(MiscUtils.color(main.getConfig().getString("chat_format")
.replace("{prefix}", LuckPermsUtils.getPlayerPrefix(player) == null ? "NOLL" : LuckPermsUtils.getPlayerPrefix(player))
.replace("{suffix}", LuckPermsUtils.getPlayerSuffix(player) == null ? "NULE" : LuckPermsUtils.getPlayerSuffix(player))));
}
Simple difference, hopefully I get NOLL TehBrianNULE in chat.
And based on the stack trace, I'm going to HIGHLY guess that it's just returning null. Let's see.
OH
I GOT IT
That's so simple.
Prefix was working fine, it's just since I don't have a suffix, it's returning null.
I feel so silly now, that makes sense.
Simple fix:
return metaData.getPrefix() == null ? "" : metaData.getPrefix();
instead of
return metaData.getPrefix();
Do the same thing with suffix counterpart and there you go.
bright tapir
Alright. Thanks a bunch haha. Perhaps on the wiki there should be "Note: Will return null if the player doesn't have one." or something like that.
crystal sonnet
That's to be assumed
nothing = null
And I'm pretty sure the Javadocs say so too
bright tapir
Huh.
Mainly just for people coming from Vault.
With Vault it just returns an empty string.
crystal sonnet
Well, there's you're issue. You've committed one of the deadly sins of programming:
Because API x does y, I'm assuming API y does so too
Especially atrocious when applied to different (but similar (sounding)) programming languages
bright tapir
Yeah, issue, I suppose.
lyric solstice
okay I had a question about the plugin luck perms how would I get it to work on 1.7.10 if It's not loading into the server what version do I need??
lyric solstice
Okay thanks
jaunty pecan
@bright tapir glad you worked it out eventually! :p
just a small pointer for future reference - you're likely to be able to apply this to other projects too
All of the API methods are annotated with @Nullable and @NonNull labels
These show up in the source code, and also in the javadocs
Nullable means a method could return null, NonNull means it never will
your IDE, if it's smart enough, should warn you about it too 😉
bright tapir
Oh I've seen those around, I've never really thought to look into them much. That makes a lot of sense haha.
Thanks a bunch! :)
jaunty pecan
this is what I mean about your IDE warning you
:p
pretty neat
it detects that getPrefix might return null, so realises that could throw an NPE
has saved me many times 😃
bright tapir
Oh, that makes so much sense. I was looking at that and thinking that, in your example, it was saying that because .length() itself could return null.
I just need to look at what it's referring to instead. Nonnull and Nullable make a lot more sense now, thank you so much haha.
jaunty pecan
cool! no worries 😃
lyric solstice
So The legacy link for 1.7.10 dose not work or load

Using this code to set temp perms. I have a mysql backend. The perm shows up in the db instanntly, but a Vault perm check only "registers" the perms after /lp sync. Any ideas? Didnt have the problem with yaml backend[03:20:54 INFO]: [LP] - Platform: Bukkit

sudden kelp
Oh well, happens with yaml aswell, no idea why I didn't catch that before
hollow grotto
In Bukkit, the correct way to abort loading your plugin was to return. What is the proper way to do so in Sponge?
@Listener
public void onServerStart(GameStartedServerEvent event) {
lpTools = new LuckPermsTools();
if (!lpTools.GetLuckPermsApi().isPresent())
return;
}```LuckPermsTools#GetLuckPermsApi just puts the LuckPermsApi instance in a Nullable. The tools class is provided for other things though - it's where I'll stick my methods for interfacing with LuckPerms.
Essentially though, LP is a hard dependency, so I need to abort loading my plugin should LP not be present.
hollow grotto
Or is that what the dependencies block of the plugin annotation is for?
jaunty pecan
@sudden kelp Would you mind creating a GitHub issue for that 😃
hollow grotto
Barring the fact that this isn't world- or server-sensitive, does anyone have any problems with the way I'm doing this? Dove into CompletableFutures for the first time today.
@Override
public CompletableFuture<String> getMeta(UUID uuid, String key) {
if (_tools.GetLuckPermsApi().isPresent()) {
LuckPermsApi api = _tools.GetLuckPermsApi().get();
return api.getUserManager().loadUser(uuid)
.thenApplyAsync(user -> user.getOwnNodes().stream()
.filter(Node::isMeta)
.filter(n -> n.getMeta().getKey().equals(key))
.collect(Collectors.toList())
.get(0))
.thenApplyAsync(Node::getMeta)
.thenApplyAsync(Map.Entry::getValue);
} else return CompletableFuture.completedFuture("");
}```On my to-do list for now is to change the key comparison to be case-insensitive, but otherwise I'm pretty happy with it.
hollow grotto
I can then call it like this:
CompletableFuture<String> titleFuture =
luckPermsService.getMeta(player.getUniqueId(), SelectedTitle);```SelectedTitle is a const string with a value of "selectedtitle", the name of the meta key for this item.
Er, const being a C# keyword roughly analogous to static final
late pike
Is it possible to get all users in a group including offline ones?
hollow grotto
Yup! Though I don't know whether you'll want to get all users and get a stream going that filters by group membership or if you can get a list by getting a handle on the group and asking it for its members.
And I don't have an IDE open currently to poke at it.
crystal sonnet
The way to do it is by loading all players and checking if they are in the group you want
stoic rock
return player.hasPermission("group." + group);
}```
This doesn't work for me :cI already checked that but It doesn't work.
Like I don't have any result
But the group exists. And my player has it in parent groups
crystal sonnet
So always false?
crystal sonnet
And keep in mind that way of checking for a player being in a group ownership is a LP only thing
stoic rock
Okay, and there is no method to get all groups of a player?
crystal sonnet
You have to use the API directly
stoic rock
Which method?
crystal sonnet
Get all permission nodes a player has and check if they are group nodes
stoic rock
Alright ty 😃

Hi, I'm trying to use the API to read out how long a player has a particular group that has been set with "addtemp". Does anyone happen to have an example?

I don’t think you can

The players should be able to read it out via ingame command /ranginfo
also yes the remaining time
crystal sonnet
Then you need to track that part yourself

Why isn't this working? ```Java

System.out.println(e.getTarget().getFriendlyName());
});

Not working and no errors & not garbage collected.

Have you doubled check that the subscribe method is called?

Using LocalizedNode#getPrefix returns an Entry<Integer, String>. The String is clearly the text of the prefix, but what does the Integer represent?

Probably the priority

That's what I would guess, but I thought I'd triple check.
crystal sonnet
Did you check the Javadocs of the method?
hollow grotto
...that would be a good idea, wouldn't it?
crystal sonnet
I mean I certainly don’t know for sure.
And Javadocs exist for a reason
Always a good idea to make sure the IDE has them included
hollow grotto
So the wiki says it's the weight. I'll hang onto those.
crystal sonnet
Or the source. So it can show the docs in the tooltips
hollow grotto
And normally they are, but IntelliJ isn't happy with me currently and isn't showing any of the javadocs.
crystal sonnet
That’s something you should fix
hollow grotto
Yeah, I'll knock that out now. Just got this method finished that's been a headache for a bit.

@hollow grotto isn't there also Vault? to collect the prefix from?

Is there a limit to the amount of text that I can store in a meta node? My plan is to serialize a List<Entry<Integer, String>> into json and store that under a meta node.
Actually, let me re-think this. If this were a static list, this would be easy to deal with, but it's dynamic. I may need to approach this from a different angle.

@hollow grotto the limit depends on the storage type
hollow grotto
I'm using the default h2 database. But what I've decided to do instead is since the integer part of that entry represents a unique id, it'd be much easier just to use a database of my own and just set up a key column that automatically generates itself.
Then I can just rely on the database to keep track of those details and I don't have to code it myself.
hollow grotto
I'm working with a SQLite database to store titles for a Minecraft server. Titles are a cosmetic chat feature which shows up before the person's name, like so: [Title] Name: Hello World!
Titles, at their most basic level, have two properties: a unique id and the text of the title. This is pretty easy - just an integer key field that auto-increments and a string value.
This is where it gets a bit more complicated though. Not all titles are available to everyone. This falls under two conditions:
- Titles owned by the player (e.g. players can donate to get custom titles)
- Titles owned by a group (e.g. staff members playing as DMs can have special titles for gods, etc.)
To complicate things further, players are stored using a unique Guid but groups are stored by a name.
What's the best way to handle keeping track of ownership? I figure there are two options for this, but I'm interested to see if you guys have any ideas.
+---------------+---------------+---------------+------------------------+
| Id (key, int) | Text (string) | Type (string) | Owner (string) |
+---------------+---------------+---------------+------------------------+
| 0 | Peasant | Group | some-random-guid-value |
| 1 | Acolyte | Player | Foxtrek_64 |
+---------------+---------------+---------------+------------------------+
+---------------+---------------+
| Id (key, int) | Text (string) |
+---------------+---------------+
| 0 | Peasant |
| 1 | Acolyte |
+---------------+---------------+
+---------------+----------------+
| Id (key, int) | Owner (string) |
+---------------+----------------+
| 1 | Admin |
+---------------+----------------+
+---------------+------------------------+
| Id (key, int) | Owner (Guid) |
+---------------+------------------------+
| 0 | Some-random-guid-value |
+---------------+------------------------+```The Type column in the first example would be mapped to an enum and would determine how to parse the owner bit.
Another idea would be to create a master table holding all titles (named "Titles") and then create a database for each user and each group, but I could see that becoming unmanageable pretty quickly.
Fortunately though, one saving grace would be that titles would only ever have one owner.
Also, I know I'll catch flak for using sqlite instead of h2, but I need this to interop with C#, and there's no good way to do that with an h2 database.
hollow grotto
I ended up going with the separate tables option.
hollow grotto
... and now I'm questioning that decision.
tribal swallow
I would have 3 tables
Titles: id, prefix
Players: player_guid, title_id, other player data fields.....
Groups: id, title_id, other group data fields
hollow grotto
So what I ended up doing was to have a single table:
+---------------+----------------+---------------------+
| Id (key, int) | Title (string) | TitleGroup (string) |
+---------------+----------------+---------------------+
| 0 | Traveler | admin |
| 1 | Merchant | Foxtrek_64 |
+---------------+----------------+---------------------+```
This `TitleGroup` is then mapped to a permission node and the permission node is applied either to the user or the group.This gives me a common "owner" no matter what the end result is, and it makes it so that the database does not care about the underlying data type of the owner itself.
So my permission node would look something like titles.group.admin or titles.group.foxtrek_64
hollow grotto
What should I be returning here instead of CompletableFuture<?>? It feels like I should be explicit in my return type, but thenApplyAsync(user -> user.setPermission(metaNode)); doesn't have a return type.
@Override
public CompletableFuture<?> setUserMeta(UUID uuid, String key, String value) {
if (getLuckPermsApi().isPresent()) {
Node metaNode = api.getNodeFactory().makeMetaNode(key, value).build();
return api.getUserManager().loadUser(uuid)
.thenApplyAsync(user -> user.setPermission(metaNode));
} else return CompletableFuture.completedFuture(null);
}```And CompletableFuture<null> isn't allowed
tribal swallow
Does it have to return a value?
Can you not just use your own method for setting the data, without the override. Sorry not a sponge person
hollow grotto
user.setPermission(node) is a void method. .thenApplyAsync gets its return type from the lambda, and with a void lambda, the return type is... ¯_(ツ)_/¯
What do you mean by "without the override?"

How do I add a user to a group with the API?
Not the primary group
as in /lp user <user> group add <group>
but programatically
sudden kelp
Create a group node with the nodebuilder and apply it to the LP user instance
More info in the lp wiki under usage
nocturne elbow
First time using the API, any docs anywhere, apart from the brief page on GH?
ah
missed that one
cheers
azure latch
Node node = api.getNodeFactory().makeGroupNode(x).build();``` what do i put where x is? or am i missing something. first time using the API as well, so learning a lotThat’s the group name @azure latch
In case it’s not the case, make sure your IDE has the API’s Javadocs or Source
azure latch
it does, thanks
azure latch
how do i add a group to a player/player to a group?
ive got an instance of a player, i just cant find a way to add a player to a group
crystal sonnet
Yes
It's under the developer section
Click on that and then more navigation should be expanded/extended
azure latch
im looking at the usage and cant see anything to do with adding groups. ive looked at modifying group data already
sorry about this, but if you have a second can you link me?
crystal sonnet
azure latch
so i would use user.setPermission(thegroupnode)?
crystal sonnet
Yes
azure latch
huh ok. thanks. clearly didnt read that right
azure latch
Using that command from earlier, no group gets assigned to me, and im not in the groups listmembers command. My code for this is here https://hastebin.com/osogokowuf.cs and there are no errors in the console or eclipse. Also, i know the worldguard API isnt the problem since the sendMessage works.
the tabbing on that looks really weird, but in eclipse its perfectly fine
crystal sonnet
azure latch
i am so dumb. this is my last one today, i promise

@azure latch code: https://paste.themelvin.nl/LTYYev

im looking
honestly, i have never used this with bungeecord before, but it looks like it could be from around for (ProxiedPlayer players: ProxyServer.getInstance().getPlayers()) { BaseComponent[] mes = TextComponent.fromLegacyText(format); players.sendMessage(mes); to me
but dont take my word for it, look for examples if you can find them, and see if any of the more experienced people will answer
crystal sonnet
@azure latch what?
azure latch
not trying to lead extreme unlucky down the completely wrong path, so wanted to see if people like you could help him
his original question is in #support-1
azure latch
yup
azure latch
public void PlayerEnterRegion(RegionEnterEvent e) {
LuckPermsApi api = LuckPerms.getApi();
Node node = api.getNodeFactory().makeGroupNode("grinder_game").build();
if (e.getRegion().getId().equals("grinder0")) {
loadUser(e.getPlayer()).setPermission(node);
api.getUserManager().saveUser(e.getPlayer());
e.getPlayer().sendMessage(ChatColor.AQUA +"Welcome to the Grinder Minigame!");
}``` can anyone tell me why .saveUser isnt working? it says it is not acceptable parameters for player@azure latch you need to pass a User instance
azure latch
``` will this work? the error highlighting is gone but want to be sureNo
You need to save the instance loadUser(e.getPlayer()) returns in a variable
Though I'm not gonna lie, this isn't programming 101 course here
azure latch
im completely new to java
azure latch
never touched it before this morning
i know, but i need this making for my server and thought id give it a shot
crystal sonnet
If you need Java help, check out the TogetherJava discord
azure latch
ok
so would User user = loadUser(e.getPlayer()); and api.getUserManager().saveUser((user)); work? sorry to keep bothering you, but id be completely lost with the console errors
crystal sonnet
Yes
As I said, best to ask for general Java help on TogetherJava
And well best to learn Java before
I hope you have at least some programming experience
azure latch
i know python very well, but had a mental block when i looked at the syntax
azure latch
i know
hollow grotto
Would anyone find it useful if I genericized this and provided it in a Maven package? https://github.com/Foxtrek64/Titles/blob/master/src/main/java/com/luzfaltex/sponge/titles/services/luckperms/LuckPermsService.java
Actually, that may not work, since these Sponge plugins don't have a base class for their main class. I'd have to provide my own framework for that.
Ah well

Hey. I'm trying to get the prefix of a player while the player is offline, but I'm having trouble doing so.
This is the code:
api.getUserManager().loadUser(pair.getKey().getUniqueId()); // Loads user from Entry key
User luckPlayer = api.getUserManager().getUser(pair.getKey().getUniqueId()); // Get User using Entry key
BungeeLogger.getGlobal().info(luckPlayer.getName()); //This prints out the correct username
Contexts contexts = api.getContextManager().lookupApplicableContexts(luckPlayer).get(); // Error occurs here
MetaData metaData = luckPlayer.getCachedData().getMetaData(contexts);
String prefix = metaData.getPrefix();```
This is the error:
```15:06:04 [WARNING] Error in dispatching command
java.util.NoSuchElementException: No value present
at java.util.Optional.get(Optional.java:135)
at commands.social.Friends.execute(Friends.java:77)
How do I solve this?
dreamy jasper
Nevermind I solved it (using deprecated methods unfortunately)
hollow grotto
@dreamy jasper Take a look at the link I sent above.
Or just this block:
@Override
public CompletableFuture<String> getUserPrefix(UUID uuid) {
if (getLuckPermsApi().isPresent()) {
return api.getUserManager().loadUser(uuid)
.thenApplyAsync(user -> user.getOwnNodes().stream()
.filter(Node::isPrefix)
.collect(Collectors.toList())
.get(0))
.thenApplyAsync(Node::getPrefix)
.thenApplyAsync(Map.Entry::getValue);
} else return CompletableFuture.completedFuture("");
}```You should avoid developing new code using deprecated methods.
The code sample there works using up-to-date code
dreamy jasper
The server is 1.8 Bungee and won't be moving from that, so if the deprecated method works right now, it'll be fine for use
As I don't have plans to run anything higher than 1.8
hollow grotto
Fair. Still poor practice.
dreamy jasper
I know, but in my eyes, if it works, why bother replacing it?
hollow grotto
"Deprecated" is another way of saying "not maintained." Should you run into any issues with the code later, any dev worth his salt will tell you to update the code to the current standard.
Also, in the event that things go against your plan and you end up needing it on later versions, the old code may not have a comparable version in the new API, causing you to need to rewrite that code anyways.
Generally, you should only use deprecated code when it either already exists or there is no code available that you should be using instead (though I would argue that in the latter case it shouldn't be deprecated).
Up to you though, really. It's your code.
dreamy jasper
Is there a simpler way of doing it without using that giant block of code you sent?
Or something that is just more readable?
hollow grotto
It's really not that bad. The worst part is that it's using a CompletableFuture.
Though that's an API choice, not mine.
And idk, I'd call that pretty legible.
I put in a new line break each time the operation changes so it's clear what's going on.
dreamy jasper
The code I'm using is much more clearer. However deprecated, it's still easier to tell what is exactly going on
hollow grotto
loadUser(uuid).join() might cause the if check to block, depending on how long it takes to retrieve the user. contexts doesn't need to exist, you can just call .getMetaData(Contexts.allowAll()); Beyond those housecleaning changes and the excess of line returns, I'd say that block is mostly okay.
Also, no point in calling .loadUser(uuid).join() if you're not going to do anything with the returned value. It's an expensive operation.
dreamy jasper
So how else do I get the user?
I need to load it from the storage in case the user is offline
hollow grotto
api.getUserManager().loadUser(uuid);
Where api is an instance of LuckPermsApi
My code will retrieve the prefix of the user regardless of whether they're on or offline, and it does it in three lines of code.
dreamy jasper
Yea but yours is extremely hard to read in my eyes
hollow grotto
In my defense, I'm a C# developer, not a Java developer.
Also, I put in those line breaks to make it easier to read.
@Override
public CompletableFuture<String> getUserPrefix(UUID uuid) {
if (getLuckPermsApi().isPresent()) {
return api.getUserManager().loadUser(uuid).thenApplyAsync(user -> user.getOwnNodes().stream().filter(Node::isPrefix).collect(Collectors.toList()).get(0)).thenApplyAsync(Node::getPrefix).thenApplyAsync(Map.Entry::getValue);
} else return CompletableFuture.completedFuture("");
}```It's still way too much in just one call
hollow grotto
That's what it looks like if you put it all in one line
Welcome to CompletableFutures and streaming?
I'm not sure what to tell you there.
If you look at code for professional products like what Google writes, that's exactly how it looks.
Well, the first example, not this abomination.
When you get into reading it, it's not terrible to look at
dreamy jasper
Will this work?
hollow grotto
User metadata is stored as a KeyValuePair in a Map.Entry<K, V>
iow I don't think your method would do much of anything... unless you're trying to get all of their meta items?
hollow grotto
@Override
public CompletableFuture<String> getUserMeta(UUID uuid, String key) {
if (getLuckPermsApi().isPresent()) {
return api.getUserManager().loadUser(uuid)
.thenApplyAsync(user -> user.getOwnNodes().stream()
.filter(Node::isMeta)
.filter(n -> n.getMeta().getKey().equals(key))
.collect(Collectors.toList())
.get(0))
.thenApplyAsync(Node::getMeta)
.thenApplyAsync(Map.Entry::getValue);
} else return CompletableFuture.completedFuture("");
}```Any time you call user.get() or user.join(), you run the risk of blocking.
So you should keep it as a CompletableFuture<String> until the last possible moment.
And then you should pass it off to a threading service.
dreamy jasper
uh well so far this has been working with no problems
hollow grotto
You've been lucky then. Blocking = lag.
