[quaint mantle]

how can I change the amount of experience for a player?

[compact crane]

player.setLevel();

[quaint mantle]

no

I don't need a level, but experience

[hard radish]

How would I setup a gradle kotlin and Java project?

[stone sinew]

Package names/class locations changed in future versions

[raven rampart]

I need some help in tying the World to the namespaced key that Minecraft uses. I do not currently see a way to link them. World.getName() isn't it, the closest I could see is World.Environment.... which uses NORMAL, NETHER, THE_END. So... I tried to create an EnumMap to handle manually tying them together. It used to work flawlessly, and now that I've pulled it out into a separate plugin, I am getting null values:

public enum Dimension {
    OVERWORLD(World.Environment.NORMAL,"minecraft:overworld"),
    NETHER(World.Environment.NETHER,"minecraft:the_nether"),
    END(World.Environment.THE_END,"minecraft:the_end");
    
    private final String namespace;
    private final World.Environment environment;
    
    private static final Map<World.Environment, String> byEnvironment = new EnumMap<World.Environment, String>(World.Environment.class);
    
    static {
        for(Dimension d : values()) {
            byEnvironment.put(d.environment, d.namespace);
        }
    }
    
    private Dimension (World.Environment environment, String namespace) {
        this.namespace = namespace;
        this.environment = environment;
    }
    
    public static String getNamespace(Location location) {
        return byEnvironment.get(location.getWorld().getEnvironment());
    } 
}

if there is a better way to do this, I'd be happy to hear it. I just couldn't seem to get that info with Spigot. PaperMC downstream has a getKey() off of world which may work, but I was trying to stay upstream.

[stone sinew]

isn't the namespace for nether just minecraft:nether and not minecraft:the_nether

[raven rampart]

Maybe

It doesn't affect the outcome of the problem I'm having though

[stone sinew]

What are the null values?

[raven rampart]

I have a task that gets a location and calls Dimension.getNamespace(location); returns null

[raven rampart]

The autocomplete for /execute in shows minecraft:the_nether

[stone sinew]

I maybe reading it wrong but the for loop namespace would be null when its first ran wouldn't it?

[raven rampart]

It's an enum, so the fields would have already been instantiated.

[stone sinew]

Try debugging it then.

[raven rampart]

... I suppose you get a lot of people in here who don't do that first, but I have and use Discord as a last resort.

[ivory sleet]

What’s the issue

[raven rampart]

The values are coming back as null

[ivory sleet]

What values specifically:0

[raven rampart]

Something is going on with the static block

as if it is not executing

[warm galleon]

1.16.5 there is no getView, getName or getTitle for e.getClickedInventory in Inventory Click Event what do i do

[ivory sleet]

Why not do everything inside?

[stone sinew]

I just tested your class it seems to be working fine for me... Are you sure the location isn't null?

[raven rampart]

Yes.

[ivory sleet]

static {
Map<K,V> map = EnumMap.noneOf(K.class);
Arrays.asList(K.values()).forEach(e -> {
map.put(...);
});
byEnvironment = map;
}

[raven rampart]

There is some odd race condition with that static block. and to @ivory sleet's point, I didn't want to have to have an instantiated reference of the class, so enum made sense, but that I would have to do it statically

[warm galleon]

1.16.5 there is no getView, getName or getTitle for e.getClickedInventory in Inventory Click Event what do i do

[raven rampart]

I just tried a different implementation:

public class Dimension {
    
    private static final Map<World.Environment, String> byEnvironment = new EnumMap<World.Environment, String>(World.Environment.class);
    
    static {
        byEnvironment.put(World.Environment.NORMAL, "minecraft:overworld");
        byEnvironment.put(World.Environment.NETHER, "minecraft:the_nether");
        byEnvironment.put(World.Environment.THE_END, "minecraft:the_end");
    }
    
    public static String getNamespace(Location location) {
        return byEnvironment.get(location.getWorld().getEnvironment());
    } 
}

Still the byEnvironment enumMap is empty

[ivory sleet]

Hmm yeah thats odd

[stone sinew]

public static String getNamespace(Location location) {
    if(byEnvironment.isEmpty()) {
        byEnvironment.put(World.Environment.NORMAL, "minecraft:overworld");
        byEnvironment.put(World.Environment.NETHER, "minecraft:the_nether");
        byEnvironment.put(World.Environment.THE_END, "minecraft:the_end");
    }
    return byEnvironment.get(location.getWorld().getEnvironment());
} 
```Try this for the hell of it

[ivory sleet]

Yeah for the record are you doing this on the main thread or not?

[raven rampart]

yes, main thread

[ivory sleet]

Then yapperyaps lazy initialization should work

[raven rampart]

wait

yes, it is the main thread

[hasty prawn]

My only guess is that static clauses are called when the class is first referenced, so maybe since you're first referencing it with a another static method, the method fires, and then the static clause is called after?

[stone sinew]

Are you running new Dimension() every time you try to get the namespace?

[ivory sleet]

Yeah cause Enum maps are not thread safe by default

[raven rampart]

So yes, adding to the map in the static method did work. I would probably throw my computer out if it didn't

Seems, dirty, but whatever this only exists because it's dirty

Thank you for your help @ivory sleet .

[ivory sleet]

Thank the others also but nice you solved it

[raven rampart]

Yeah, I hit enter too quickly, I was trying to tag @stone sinew as well.

Thank you

[ivory sleet]

Alrighty cool

[stone sinew]

I didn't do much but you're welcome lol

[quaint mantle]

I have a tpData.json file but does anyone know how I can get my reader to use it without the absolute path?

Reader reader = Files.newBufferedReader(Paths.get("C:\\Users\\gaela\\IdeaProjects\\AdvancedChorusFruit\\src\\main\\java\\me\\jiovannyalejos\\advancedchorusfruit\\tpData.json"));

I'm trying to find a way so that it'd work without an absolute path so probably a relative path or smt, so that others could also use it

[ivory sleet]

Yes

Path.of(".") should give you the directory the application was bootstrapped in

[stone sinew]

Had to look at one of my discord bots to find that xD

[ivory sleet]

x)

[iron basin]

Does anyone know how to add custom entry fees for Portals?

[quaint mantle]

hmm so like would this work?

Reader reader = Files.newBufferedReader(Paths.get(".\\AdvancedChorusFruit\\src\\main\\java\\me\\jiovannyalejos\\advancedchorusfruit\\tpData.json"));

[ivory sleet]

Yeah well how are you running this?

Is it like dev environment runtime?

[quaint mantle]

?

[ivory sleet]

Obviously that code of yours can’t be production ready

[quaint mantle]

it's in a listener class that reads the tpdata file so it knows where to teleport the player

w-wait wdym?

[ivory sleet]

You’re running a server in your dev workspace src folder?

[quaint mantle]

no, i'm running it in a separate folder and the plugin is just in the plugins folder in the same directory as the server

or as the server startup jar

[ivory sleet]

I’m confused but I guess, isn’t that path wrong then?

[quaint mantle]

wait, how so?

[ivory sleet]

Usually data is stored in plugin folders

Not in the java source folder of your work space

[stone sinew]

If you want the datafolder of your plugin just run JavaPlugin.getDataFolder()

[quaint mantle]

wha- sry i'm just learning some new things rn, so the getdatafolder() would get it in which directory? and could it get the json file if i move it there?

[ivory sleet]

Yes

[stone sinew]

What ever the name of your plugin is... so plugins/<pluginName>

[fluid cypress]

whats the difference between Bukkit.getPluginManager().isPluginEnabled() and getServer().getPluginManager().isPluginEnabled()?

[silver shuttle]

Bukkit.getPluginManager().disablePlugin(this);
Does that in the main class disable the plugin?

[quaint mantle]

so that would be in this dir, right? but i don't see it i think

[stone sinew]

Just api instance. getServer() or Bukkit.

[stone sinew]

Should be able to drag and drop the file into your compiler. I thought you were talking about getting the plugin folder for your plugin

[quaint mantle]

th-the compiler?

[stone sinew]

your ide...

[quaint mantle]

ohh, i thought you meant the thing that turns the readable code to macine code

i think-

unless you meant smt different-

[stone sinew]

No you're right. Just drag and drop the file where you want it to be saved in your project

[quaint mantle]

ahh ok

[ivory sleet]

Static call vs instance call

If we talk about unit testing the instance call is better

Even when we talk about object orientation

There might be a reason that more than one server instance exist at the same time which the Bukkit class obviously wouldn’t be capable of handling however in a spigot plugin context using the Bukkit class is probably benefiting since it’s less verbose.

[quaint mantle]

So you made me realize something, this is the directory to my json file that's being used in my ide but not for the one that would be in my compiled jar file....

Reader reader = Files.newBufferedReader(Paths.get("./src/main/resources/TeleportData.json"));

but to get it from the plugin folder, i have to use JavaPlugin.getDataFolder() which would be the resources folder? but then the "./src/main/resources/TeleportData.json" bit wouldn't make sense I think, and there's a plugin.yml file in resources as well, so how do i specify?

[torpid zinc]

How could I check if a player sent 3 or more messages in the last 5 seconds?

I made a player cache, I figured I would log chat messages but I can't seem to find a way to know when they were sent nor when to delete that data to limit ram usage

[stone sinew]

When you put the file in your project you would use getResource("file").getBufferedReader() since you will be getting the file from your jar.

[stone sinew]

just save the time of player messages using System.currentTime()

If the list of times has more then 3 remove the first (the one further from the current time)

[quaint mantle]

so getResource is a method in the Javaplugin class so I have to use it in my main (?) so i assume i have to use

File TeleportData = new File(getResource("TeleportData.json").getBufferedReader());

as a variable that i can get in my listener class?

but the getBuffered reader doesn't seem to be a method i could use, since it isn't showing up(?;-;?)

[silver shuttle]

Bukkit.getPlayerExact(args[0]) == null && Bukkit.getOfflinePlayer(args[0]) == null

Is this true if args[0] is the name of a non existing Player?

[stone sinew]

Or just make an instance of your main class accessible by other classes.
My bad getResource is an input stream so you have to cast it to buffer reader.

InputStream infoFile = getResource("file");
BufferedReader info = new BufferedReader(new InputStreamReader(infoFile));

[stone sinew]

If a player with the username specified has never joined the server it should return true. (I could be wrong though)

[silver shuttle]

I'll test it

welp it always returns false

if he hasnt joined and if he doesnt exist

[stone sinew]

👍

[silver shuttle]

How would I check if a player name simply exists? Without the UUID?

[stone sinew]

You would have to check the mojang api

[silver shuttle]

there's no other way?

[stone sinew]

No the server can only tell you playernames that have joined.

[silver shuttle]

okay

[quaint mantle]

sorry, i took a bit since i had to do a chore, so the path would be something along this line?

Reader reader = Files.newBufferedReader(Paths.get(new AdvancedChorusFruit().info));

which i feel is almost what i'm supposed to do...

toString would not return the path right?

[stone sinew]

new AdvancedChorusFruit() is a class. not a path.

[stone sinew]

Show the code you have currently where you are trying to get a reader

[quaint mantle]

wait, what's the difference between an instance of my class and an object of it again...

oh, ok

[quaint mantle]

it's in my PlayerTeleportEvent listener class

[stone sinew]

Instance is something accessible you save like a variable.

[quaint mantle]

ohhhh

[stone sinew]

?paste

[undone axle]

https://paste.md-5.net/

[quaint mantle]

https://paste.md-5.net/efefayuxeh.java

InputStream infoFile = getResource("TeleportData.json");
public static BufferedReader info = new BufferedReader(new InputStreamReader(infoFile));

so i'd do this in main and then just get it in the Paths.get() except getting the path first(??)

[stone sinew]

Add the file to your project like this then use the above code to access the file within your plugin.

[quaint mantle]

the- the first line has an error warning when i try to make it static
Non-static method 'getResource(java.lang.String)' cannot be referenced from a static context

[stone sinew]

in your main class add

private static <ClassName> instance;

public void onEnable() {
    instance = this;
}

public static <ClassName> getInstance() {
    return instance;
}
```If you need to get a variable or such from your main class just use `<ClassName>.getInstance()`

[quaint mantle]

ohh, that's actually pretty smart

[silver shuttle]

how to get the current UNIX timestamp?

[stone sinew]

System.currentTimeMillis()

[silver shuttle]

thats not the unix timestamp

[stone sinew]

My bad maybe use Date

[silver shuttle]

Is it this maybe?
System.currentTimeMillis() / 1000L

just remove the milliseconds?

[stone sinew]

Date date = new Date();
date.getTime();

[quaint mantle]

So i feel like i'm very close, but i'm not sure how to get the file path of info, which, i'm not exactly sure what the BufferedReader type object is so i'm not sure if i actually need the path still

Reader reader = Files.newBufferedReader(Paths.get(AdvancedChorusFruit.getInstance().info));

[stone sinew]

Did you add the file to your project?

[quaint mantle]

i did

[stone sinew]

screen shot

[stone sinew]

InputStream infoFile = <ClassName>.getInstance().getResource("TeleportData.json");
public BufferedReader info = new BufferedReader(new InputStreamReader(infoFile));
CoordinateData data = gson.fromJson(reader, CoordinateData.class);
if(data.locNames.contains(itemDisplayName.substring(5))) {
    String[] coords = data.coordinates.get(data.locNames.indexOf(itemDisplayName.substring(5))).split(Pattern.quote("|"));
    event.setTo(new Location(player.getWorld(), Double.parseDouble(coords[0]), Double.parseDouble(coords[1]), Double.parseDouble(coords[2])));
    reader.close();
}

[quaint mantle]

wh-

oh

oh ok i thought all that was new

ohh, so i only needed the class instance and not have the inputstreamstuff in it

[silver shuttle]

How do I get the timezone the server is in?

In the format "GMT-4" for example

nvm

[vast sapphire]

my simple explosive bow isn't creating an explosion at the arrow location? ```java
@EventHandler
public void bowShoot(ProjectileHitEvent e) {
Player p = (Player) e.getEntity().getShooter();
assert p != null;
if (p.getInventory().contains(arrow())) {
if (p.getInventory().getItemInMainHand() == bow()) {
e.getEntity().getWorld().createExplosion(e.getEntity().getLocation(), 1, false);

            e.getEntity().getWorld().playEffect(e.getEntity().getLocation(), Effect.WITHER_BREAK_BLOCK, 1);
            e.getEntity().remove();
        }
    }
}```

[stone sinew]

??? getResource() is an input stream. BufferedReader takes an InputStreamReader.

[stone sinew]

1. player can swap items before arrow lands.
2. Bows take the arrow from the players inventory.

[vast sapphire]

just testing the bow atm

[real spear]

Question: what is the best method for making your commands autocomplete?

[vast sapphire]

why isn't the bow working?

[quaint mantle]

Ohhh ok, but thank you, it works perfectly now :)

[stone sinew]

public List<String> onTabComplete(CommandSender sender, Command cmd, String label, String[] args) {} and register it like a command... getCommand("cmd").setTabCompleter(TabCompleter);
public class <ClassName> implements CommandExecutor, TabCompleter

[quaint mantle]

wait, i meant that the inputstream stuff was in my main as variables when it didnt need to be also

[stone sinew]

What do you mean? Not working how?

[vast sapphire]

the explosion is not created at the arrow location

[stone sinew]

Oh you said the bow in the last message.
Debug it check if its actually being ran.

[vast sapphire]

alright

[stone sinew]

And remember you're using ProjectileLandEvent not ProjectileLaunchEvent (I say this because the method is named bowShoot)

[silver shuttle]

How do I essentially cancel the PlayerJoinEvent? Or prevent them from joining

[stone sinew]

player.kick(String)

[silver shuttle]

simply that on joinevent?

and it doesnt cause any interference with other joinevents?

[silver shuttle]

What is the check with vault to see if an OfflinePlayer has a specific permission?

[torn oyster]

what would be the most efficient way

to find all the possible spawns in skywars

like

how do i iterate through all the blocks

and find all the locations

in the glass cages

or do i have to manually enter them in

[quaint mantle]

just save the locations?

[rigid otter]

Hello! What difference between getBlock() and getBlockPlaced() in BlockPlaceEvent?

[vague oracle]

Have a method to get all the blocks in a pattern and the parameters will be the 1 or 2 blocks of air in the middle

[torn oyster]

im thinking of adding a /addspawn

it literally just adds a spawn at ur location in a config

then when the game starts it iterates through all of them, adds em to a list

[hexed hatch]

Why would you do that when you can just store the spawn locations themselves?

[rigid otter]

Anyone know?

Hey y'all!
Is there a way to store data in an items's PersistentDataContainer as an ItemStack?

[torn oyster]

how

do i get this

Location{world=CraftWorld{name=world},x=-28.5,y=73.0,z=15.5,pitch=0,yaw=-180}

and make it a location object

[stone sinew]

Well yeah lol... but you said PlayerJoinEvent

[torn oyster]

hey yappery

could you help

[stone sinew]

I can try, no promises

[torn oyster]

a

[stone sinew]

Well looks like a json string so just parse it using json... JSONObject data = (JSONObject) new JSONParser().parse(String);

[torn oyster]

im trying to convert it to a location

[stone sinew]

yeah parse as json then use the out put... data.get("x") and make a location

[torn oyster]

ok

[stone sinew]

My bad Location has serialize and deserialize methods. Just deserialize it.

[torn oyster]

oh, how?

i did location.tostring

and im retreiving a list<String> from my config of all the locations

[stone sinew]

https://www.spigotmc.org/wiki/serializing-location-objects/

[torn oyster]

uhm

that doesnt apply to me

[stone sinew]

Where are you putting the location that you need .toString() then?

[torn oyster]

spawns:
- Location{world=CraftWorld{name=world},x=-28.5,y=73.0,z=15.5,pitch=0,yaw=-180}
- Location{world=CraftWorld{name=world},x=-43.5,y=73.0,z=0.5,pitch=0,yaw=-90}
- Location{world=CraftWorld{name=world},x=-28.5,y=73.0,z=-14.5,pitch=0,yaw=360}
- Location{world=CraftWorld{name=world},x=0.5,y=73.0,z=-42.5,pitch=-0,yaw=-360}
- Location{world=CraftWorld{name=world},x=-13.5,y=73.0,z=-28.5,pitch=0,yaw=-90}
- Location{world=CraftWorld{name=world},x=14.5,y=73.0,z=-28.5,pitch=0,yaw=-270}
- Location{world=CraftWorld{name=world},x=29.5,y=73.0,z=-14.5,pitch=0,yaw=-360}
- Location{world=CraftWorld{name=world},x=44.5,y=73.0,z=0.5,pitch=0,yaw=-270}
- Location{world=CraftWorld{name=world},x=29.5,y=73.0,z=15.5,pitch=0,yaw=-180}
- Location{world=CraftWorld{name=world},x=15.5,y=73.0,z=29.5,pitch=0,yaw=90}
- Location{world=CraftWorld{name=world},x=0.5,y=73.0,z=44.5,pitch=0,yaw=180}
- Location{world=CraftWorld{name=world},x=-14.5,y=73.0,z=29.5,pitch=0,yaw=270}

thats what my list looks like

i want to turn that into a list of locations

[stone sinew]

Why not just create your own string of the location then so its easier to grab?

public String locationToString(Location loc) {
    return loc.getWorld().getName()+","+loc.getX()+","+loc.getY()+","+loc.getZ()","+loc.getYaw()+","+loc.getPitch();
}

public Location stringToLocation(String string) {
    String[] data = string.split(",");
    return new Location(Bukkit.getWorld(data[0]), Double.valueOf(data[1]), Double.valueOf(data[2]), Double.valueOf(data[3]), 
        (float) Double.valueOf(data[4]), (float) Double.valueOf(data[5]))
}

[torn oyster]

because i already made all the locations and i do not want to do it again

12

[stone sinew]

Then gotta json parse it Like I said above.

[torn oyster]

okay

[eternal oxide]

Locations are already serializable, you can literally put the list into the config with one line of code

[stone sinew]

He wants to get them from config not add to it.

[eternal oxide]

yes, once added they are auto serialized, which means you can easily retrieve them

[stone sinew]

No.... he already has them listed... he wants to convert his already made config to locations not add to the config

[eternal oxide]

Those are simple toString() of Locations, so he has them in code already

its 10 seconds to output in teh correct format

[worn oak]

i'm pretty sure you can fetch from json as a raw object then try casting it to Location

[torn oyster]

already did it

managed to do it

i used json parsing and something idk

[paper geyser]

ok so i deleted this bc i thought i figured it out but i was wrong-

this code:
https://paste.md-5.net/juwuzimuno.cs
spits out this error:
https://paste.md-5.net/cugegewefi.cs
for this table:

     |   0  |    0    |     0```


any idea why? I get its trying to say theres no MANAREGEN in the table which is right but I dont mention MANAREGEN, I mention MANA_REGEN. Line 159 is ``ps.executeUpdate()``

That’s strange because underscores are perfectly legal for table names.

[paper geyser]

yeah

what do you think i should do? Just change the name of the table to MANAREGEN

[native nexus]

Give that a go and see if it makes a difference.

Do you have the full code snippet?

[paper geyser]

uhhh sure

but I've just changed it to not have the underscore

well

for some reason that fixed it?

[native nexus]

Yeah that is bizarre

[paper geyser]

oop

but

the code only runs on first join and when I joined a 2nd time

now theres 2 of my uuid and stats

here's my full code

yup

it also doesn't update when i leave?

[eternal oxide]

in your schema set your UUID column as a primary key/unique

[paper geyser]

im sorry this is my first time using SQL what does that mean-

[hardy swan]

a primary key and unique keys are columns that accepts no duplicates

simply put

[paper geyser]

ahhh

how would I do that with phpmyadmin?

wait

i can google that

[hardy swan]

you should declare your tables' schema that uuid is your primary key

[hardy swan]

what SQL db are you using

[paper geyser]

wait-

im using phpMyAdmin for my db

i think thats what you're asking? But if you dont know its a MySQL database

if thats what you're asking

i'm so sorry i'm not very knowledgeable in mysql stuff haha

[hardy swan]

I mean MySQL haha

[paper geyser]

alright cool

[hardy swan]

phpMyAdmin is just a software helping you manipulate the sql database

[late stone]

is there any way to disable firecharge (projectile) from exploding and setting fire

[paper geyser]

swag

[paper geyser]

https://bukkit.org/threads/disable-explosion-fire-from-fire-charge-projectile.223356/ idk if this would help but basically get the fireball that's launched when a fireball is launched then setIsIncendiary(false);

[rustic gale]

 public HashMap<String, String> PlayerGuilds = new HashMap<String, String>();

 public void UpdatePlayerGuilds(String player, String guildName) {
        PlayerGuilds.put(player, guildName);
    }

UpdatePlayerGuilds is called from a seperate class like this

PlayerGuildData playerGuildData = new PlayerGuildData();
playerGuildData.UpdatePlayerGuilds(player.getName(), "test");

the problem is that the hash map doesn't save. when this function is called

public String GetPlayerGuild(String player) {
        if (PlayerGuilds.get(player) != null) {
            return PlayerGuilds.get(player);
        }

        return "Error - Player is not in a guild";
    }

Error - Player is not in a guild is returned because PlayerGuilds.get(player) is null.

so why doesnt the hash map save?

[maiden thicket]

pls use camelCase 🥲

but uh

are you reloading after running the update method

are you restarting

[lost matrix]

Dont make data structures public. Make them private final and write accessors for them.

[lost matrix]

Next: Never use a players name for identification because a minecraft name can be changed. Use the players UUID.

[lost matrix]

We need more infos. You probably have multiple instances of the class that contains the "PlayerGuilds" map.
Also: Nothing in memory is saved. If the server shuts down then you start with new, clean instances.
If you want to persist data over restarts you need to write the data onto your disk.

[lost matrix]

If your DB is busy while a player connects then you produce massive lag. If a connection starts hanging then your server just crashes.

[paper geyser]

hmm?

so like \

basically the situation is

on first join it adds them to the thingy

and saves when they leave

would that still produce alot of lag often?

bc itd be used in those situations

[lost matrix]

Events are executed on the main thread. If you connect to a database in an event and the connection starts hanging then you block the whole server. If this lasts several seconds then the server just crashes.

[paper geyser]

ahhh

whats a better way to do this then?

also i've changed my code

idk how much it helps but

[fluid cypress]

can a World object change somehow? besides deleting it. is it safe to use it as a map key?

[paper geyser]

https://paste.md-5.net/vaqozogugo.cs

[lost matrix]

Worlds have UUIDs which should be used. You can use a World object but if you are not careful then you will end up with a massive memory leak.

[lost matrix]

Connections to databases should always be done async.
In your case you should just use the AsyncPlayerPreLoginEvent and fetch your DB data in there.

[paper geyser]

ahhh ok

ok but then how do I get the event player?

i see event.getUniqueId

but i'd have to change alot of stuff for that to work

[lost matrix]

You dont.

[paper geyser]

ahhh ok-

but the event.getUniqueId is the player's UUID right?

[lost matrix]

If the user is not in the DB then just set default values.

[paper geyser]

alright cool

[wispy monolith]

why does mojang still uses this very old mechanic and uses the single-thread server, is there a way to change that using a plugin or something in spigot?

[lost matrix]

lol no. Almost every game has a main thread. Also this is deeply rooted within minecrafts code. You would need to completely re-write the entire game from ground up in order to introduce proper multi threading.

[wispy monolith]

but isn't the single-thread thing annoying

[paper geyser]

is there any async quit event? I cant find anything so I'm assuming no

but i figured i'd try my luck haha

[regal moat]

Guys. Help. I want to summon a falling block and teleport it wherever the player looks

[ionic reef]

Quick question: should I create a MySQL table for each part of my plugin, or join a few together and have a few seperate. e.g Do I create a table called 'playerdata' which can store their friends, their balance, profile info etc, or do I have one table for friends, one table for economy, etc

[lost matrix]

Nope. Just spawn a new thread

[paper geyser]

yup! just figured it out but thanks for the reply

appreciate people like you alot smile, helping people out just to help :)

[lost matrix]

Could you elaborate a bit more?

[paper geyser]

my system just has a 'playerdata' table system but i'd say it depends on the complexity

[ionic reef]

hmm yeah

which one would you say would be easier to work with/more organised

[lost matrix]

If you want to have one centralised data structure then a relational database is a bad idea. Relational databases are made for relational data. So one table for every new type of data that has a relation to a user.

[ionic reef]

Yeah that makes sense

cheers man

[ionic reef]

hangon wait no it doesnt make sense :P

so should I make a new table for every new type of data or not

[lost matrix]

If you want to use a relational database then yes. You should make a new table for different types of data.
But it also depends on the scope of your project.

If your plugin is a monolith that is used to run a server then you should def split up your data. If you only provide a plugin for others to use then you can get away with just one table containing all your player data.

[ionic reef]

It's going to be used to run the core aspects of a server so sounds like splitting it up is the way to go

tysm for the clarification

once again cheers :)

help plz

s is valid json

i think

[lost matrix]

Jackson?

[torn oyster]

unless this isnt json
Location{world=CraftWorld{name=world},x=-28.5,y=73.0,z=15.5,pitch=0,yaw=-180}

[lost matrix]

This isnt json

[torn oyster]

what is it then

i did Location.toString() how do i do something like Location.fromString()

[lost matrix]

lol

[torn oyster]

idk lol

[lost matrix]

Where do you want to store the location. In a yml file?

[torn oyster]

yes

[lost matrix]

Then just throw it in. Location already implements ConfigurationSerializable.

[torn oyster]

wdym

its in a string list

[fluid cypress]

if i throw an exception, i dont have to return to stop the code execution, right?

[lost matrix]

Yes. But in some cases its a good idea to manually handle the exception.
Or do you mean you throw a new exception yourself.

[ionic reef]

Also another question: can I/how can I store lists in a MySQL table?
(Friends list)

[fluid cypress]

i throw the new exception myself

[lost matrix]

Then the code execution stops right there.

[lost matrix]

Serialize one Location

    YamlConfiguration configuration;
    Location location;
    configuration.set("SomeLocation", location);

Deserialize one Location

    final YamlConfiguration configuration;
    final Location location = configuration.getLocation("SomeLocation");

Serialize a List of Locations

    YamlConfiguration configuration;
    List<Location> locationList;
    configuration.set("ABunchOfLocations", locationList);

Deserialize a List of Locations

    final YamlConfiguration configuration;
    final List<Location> locationList = (List<Location>) configuration.getList("ABunchOfLocations");

[torn oyster]

is this getting or setting

oh okay lol

hopefully this works >.<

[rigid otter]

Why need to be cloned? https://ibb.co/xsJfHm2 <-- image

[torn oyster]

what do i do then

[lost matrix]

Look at the examples form above.

[lost matrix]

More context pls.

[rigid otter]

In image

[torn oyster]

okay

[lost matrix]

More context to the image pls

[rigid otter]

Item#ItemMeta(), it return a cloned item meta

Why don't just not clone, then we no need to Item#setItemMeta() when set

[lost matrix]

Yes. But we need more context or else we cant say if it makes sense or not. Generally you dont want to clone objects unless you want to provide immutablity.

Ah i see. So the context is: This is spigot source code

[torn oyster]

i guess i gotta remake all those locations

rip

[rigid otter]

World#getBlockAt() is not cloned

[lost matrix]

Changes to the ItemMeta would not be reflected to the NMS ItemStack anyways. So making it immutable makes it more clear.

[rigid otter]

Yes, but I want to know why, the reason need to be cloned

[rigid otter]

Ohh 🤔

[lost matrix]

Because ItemMeta has no direct handle like Block has.

Its an abstract model introduced by spigot

[rigid otter]

Then, they update the item when applying item meta? Ok!

[lost matrix]

You could make changes to the NMS ItemStack every time the ItemMeta changes. But that would be way more expensive than just applying all changes in bulk once.

So spigot (or rather bukkit) opted for this approach.

[rigid otter]

Ok thank you!

[regal moat]

i have an item when you right click blocks with it, the block turns into a falling block and teleports itself 5 blocks from your eye location

https://paste.md-5.net/amonaqajew.java

the code

it just breaks the block

no falling block entity

[lost matrix]

Do you want it to be exactly 5 units away at all times or on top of the Block the player is looking at?

[regal moat]

at all times

[lost matrix]

This code will cause lags really fast. You will have thousands of runnables stacked up in no time.

[lost matrix]

Ill write you an approach

Dont

Where do you want to store the ItemStack?

[torn oyster]

works, tysm

[lost matrix]

ItemStack implement ConfigurationSerializable.
So you should try to serialize/deserialize the class using those methods. Try putting the Map<> returned by ItemStack#serialize() into Gson

Might work

Doesnt work...

Does it need to be readable? Or can it also just be a Base64 String?

Ill just give you my methods. You need NMS on your classpath for this to work:

  public static String serialize(final ItemStack itemStack) {
    final NBTTagCompound tag = new NBTTagCompound();
    CraftItemStack.asNMSCopy(itemStack).save(tag);
    return tag.toString();
  }

  public static ItemStack deserializeItemStack(final String string) {
    if (string == null || string.equals("empty")) {
      return null;
    }
    try {
      final NBTTagCompound comp = MojangsonParser.parse(string);
      final net.minecraft.world.item.ItemStack cis = net.minecraft.world.item.ItemStack.a(comp);
      return CraftItemStack.asBukkitCopy(cis);
    } catch (final CommandSyntaxException ex) {
      ex.printStackTrace();
    }
    return null;
  }

[grim ice]

@lost matrix btw

is it fine if i dont understand any shit in nms

its all random letters and shit

[opal juniper]

wait… does the serialize method not work?

[lost matrix]

In 1.17 its all obfuscated. You need to apply the mojang mappings in order to understand anything in there. I could just extrapolate on previous versions because i have been digging in NMS for a while so i can find out what methods/filds do/mean
just by looking at return types and patterns etc. But if you want to properly understand whats written there you can just apply moj mappings

[lost matrix]

It does work but i couldnt figure out how to deserialize it again. The resulting ItemStack lost all metadata.

[grim ice]

aaaa ok

[opal juniper]

oh balls

i’m using that atm

will have to have a look

you can just base64 it right? i seem to remember that being a thing

[lost matrix]

    final Gson gson = new GsonBuilder().disableHtmlEscaping().setPrettyPrinting().create();

    final ItemStack itemStack = new ItemStack(Material.DIAMOND_AXE);
    final ItemMeta meta = itemStack.getItemMeta();
    meta.addItemFlags(ItemFlag.HIDE_ATTRIBUTES);
    meta.setDisplayName("§eCool Axe");
    meta.addEnchant(Enchantment.ARROW_DAMAGE, 3, true);
    itemStack.setItemMeta(meta);

    System.out.println("Item: " + itemStack);
    System.out.println("------------------------------------");
    final String json = gson.toJson(itemStack.serialize());
    System.out.println(json);
    System.out.println("------------------------------------");
    final ItemStack deserializedItem = ItemStack.deserialize((Map<String, Object>) gson.fromJson(json, Map.class));
    System.out.println("Item: " + deserializedItem);
    final String json2 = gson.toJson(deserializedItem.serialize());
    System.out.println(json2);

Made:
Item: ItemStack{DIAMOND_AXE x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, display-name={"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"yellow","text":"Cool Axe"}],"text":""}, enchants={ARROW_DAMAGE=3}, ItemFlags=[HIDE_ATTRIBUTES]}}
to
Item: ItemStack{DIAMOND_AXE x 1}
One could probably figure out whats wrong but i didnt really bother

[opal juniper]

myeah

[paper geyser]

hi me again uhmm

ive been struggling with this for about an hour and I just can't get it so-

[grim ice]

Where are the mojang mappings?

[paper geyser]

im trying to update a player's stats

Main.prepareStatement("UPDATE playerinfo SET MANA = '100', MAXMANA = '100', MANAREGEN = '2' WHERE UUID = '" + player.getUniqueId() + "'").executeUpdate(); doesn't work

[lost matrix]

Read all of this:
https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/

[grim ice]

oh god ok

[opal juniper]

yeah it talks about the buildtools command

[paper geyser]

java.sql.SQLException: No value specified for parameter 1

wait-

let me try something

yeah no that didn't work

I'm just extremely confused and lost and in need of resources or just assistance

[grim ice]

eh

i wont bother with nms tbh

too complicated for me

[lost matrix]

Show us some more code pls.

What do you want to achieve?

Ok. So for saving you probably want to upsert.
Upsert means -> Insert but if key exists then update

[paper geyser]

but ig I could just have it do the actually variables? idk why I hardcoded it

[old sun]

well I’m sorry but just shut ur trap then would u

[paper geyser]

alright! thanks will look into it

[old sun]

sheesh so annoying

[paper geyser]

much appreciated thank you smile

[old sun]

Happy now 🙂

[paper geyser]

id like to share

that the issue that I was struggling with for 2 hours was because I had this line of code

final static String INSERT_QUERY = "INSERT INTO playerinfo (UUID,MANA,MAXMANA,MANAREGEN) values(?,?,?,?)";

lol

thought that was funny

anyways

[opal juniper]

how to encode itemstacks in b64?

wait nvm

needed to scroll xD

[lost matrix]

Just pipe a BukkitObjectOutputStream into a byte[] and let it be encoded in Bas64

[opal juniper]

ok

[lost matrix]

Something like this:

  public static String itemStackToBase64(final ItemStack item) {
    final String line;
    final ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    try (final BukkitObjectOutputStream dataOutput = new BukkitObjectOutputStream(outputStream)) {
      dataOutput.writeObject(item);
      line = Base64Coder.encodeLines(outputStream.toByteArray());
    } catch (final IOException e) {
      e.printStackTrace();
      return null;
    }
    return line;
  }

[opal juniper]

thanks

saved me from stack overflow

what is the best way to get back to ItemStack

cause the ItemStack#deserialise takes a map

not b64

[eternal night]

the bukkit object input stream ? 😅

[opal juniper]

myea

but how do i get object from it

final ByteArrayInputStream inputStream = new ByteArrayInputStream(Base64Coder.decodeLines(base64));
final BukkitObjectInputStream dataInput = new BukkitObjectInputStream(inputStream);

damm

im dumb

[eternal night]

I think ObjectInputStream#readObject

[opal juniper]

yep

idk how i missed that

help

[regal moat]

help

[lost matrix]

This plugin will be quite hard to write as the movement of falling blacks doesnt seem fully server authoritative:

[paper geyser]

you could do it better with command blocks

[lost matrix]

No

Fks up your performance

[paper geyser]

fair

probably bad option for servers

[lost matrix]

You need to do that with packets and some NMS

[paper geyser]

but i've seen it smoother with command blocks at least

[paper geyser]

yeah this is probably your best bet

[lost matrix]

Let me try a quick setup

[quaint mantle]

Why would command blocks Change anything?

[paper geyser]

im not really good with command blocks but

it goes off 2 ideas

1. I've seen command blocks do a good job with this exact thing
2. I trust smile's statement that the falling block option wouldn't work the way it's desired

but the command block option presents issues for server side things

[quaint mantle]

They (the commands) are not sent to the client

[paper geyser]

mhm

[quaint mantle]

So If it works with command blocks it will also work with plugins

[paper geyser]

probably

[regal moat]

i feel like you could turn off gravity for falling blocks?

[eternal night]

turning off gravity prevents an entities velocity from being applied tho

it is a shitty system

[regal moat]

huh

[eternal night]

oh you don't use velicity

you just teleport

then yea

[regal moat]

can you just send the code you are using right now? i can just modify it.

[regal moat]

well i want to throw the block, but i can easily turn it on again when i try to throw it

yeah

[lost matrix]

This seems to work and is packet based so the falling block doesnt get ticked.

[oblique pike]

Is there any way to get nearby tileentities?

[paper geyser]

:0 this is really smooth

do you guys mind if I nab it? (Core and Smile)

[regal moat]

Alright, can you send the code?

[regal moat]

well its for my WIP minecraft server. but since its WIP, sure

[paper geyser]

if smile ever sends the code to me

it will automatically run toString()

[lost herald]

Ok thanks

[supple elk]

if you do something like (EntityType.WHATEVER + "")

that might not be the same as .name() however so be careful

[lost herald]

Can it cause an internal irror?

[quaint mantle]

What does EntityType return?

[lost herald]

ingame

[quaint mantle]

If it returns a string then go for it, but I feel it does not

So you’d need to use .name

entity type is an enum not a function, it doesn't return anything :?

it's an instance of mcuteam

oh so I can't cast like that

[unreal quartz]

no

[supple elk]

ugh

[lost herald]

guys if i do that if statement do i need ((LivingEntity) entity)?

[unreal quartz]

i suppose the sethealth method is a member of livingentity, so yes

[supple elk]

what do I do instead then? I have a bunch of minigames, through which the teams earn points across

for each game I want to store information about each team, but I don't want to put that information in the team class as it's only used for the one minigame

[lost herald]

i mean this code doesn't run if the entity is not livingentity

[unreal quartz]

yes but the sethealth method is defined by the livingentity class so you must cast it to use it

[supple elk]

oh

I use a wrapper

that's what I do

I'm fucking dumb

Oh, i did not do state.update()

Solved

Where else do I put api questions?

[quaint mantle]

how can I check if a player has any inventory open?

[crude charm]

some php discord

[stiff topaz]

This is spigot related

Not php

Gets the inventory view the player is currently viewing. If they do not have an inventory window open, it returns their internal crafting view.

[quaint mantle]

Yes

[supple elk]

How can I sort a list of this class in order of sheep from highest to lowest

[oblique pike]

Check if it's not their internal crafting view

[quaint mantle]

isn't the internal crafting view the players own inv?

[oblique pike]

It is

[quaint mantle]

I wan't to check if the player has any inv open

also the own

[green forum]

Hello i'm trying to send two PacketPlayOutNamedEntitySpawn with same UUID in the GameProfile for spawn two NPC with same skin but just one is visible, someone know about this probleme ?

[vale cradle]

player.getOpenInventory() != null

[vale cradle]

player.getOpenInventory().getType() == InventoryType.PLAYER ig

[supple elk]

how is this possible...

every time change is set true it should then detect it

[ancient plank]

maybe because it runs through the for loops b4 reaching your if(change) part?

[supple elk]

yes but it's not like I set it false again

these events are spaced out

each change set true you can see in that screenshot is an entirely different run over of the for loop

anyway I fixed it by using an atomic

[regal moat]

help me please

help

[vale cradle]

bcs you declared the variable in the same scope

[supple elk]

why would that be a problem?

[vale cradle]

when the scope is called again, you'll have the variable false again

[regal moat]

can y'all help me, please?

[vale cradle]

Which NMS version are you using?

[supple elk]

how does that work?

I know it resets to false every time, that's the point

the problem is that I run code immediately after setting it to true

but for some reason it's been set to false again before that

[regal moat]

1.17.1

[supple elk]

I check immediately after it's set to true before it should have the chance to be set back to false

[vale cradle]

which event was being called from?

[regal moat]

the event works but the part i shared doesnt

it just

stuck midair

gravity is on for the falling block btw

[tardy delta]

is this something?

public class ActionBar extends BukkitRunnable {

    public ActionBar(Player player, String text, int seconds) {

help me please

[lost matrix]

What problem do you have?

[regal moat]

explained it

replied to it i mean

https://paste.md-5.net/yorajarima.coffeescript tryinna add velocity to a nms entity. its supposed to boost em up wherever i look at but no. wont work.

i also tried to add fallingBlock.show()

but it just made it dissapear

wait

i am trying something

[lost matrix]

The StaticFallingBlock class is completely packet based. That means setting the velocity of it wont cause the Block which is shown to a user to fly because the user doesnt receive the movement packets.
Also, the velocity is set using the setMot() method

[regal moat]

now i can drop the block

but not give it velocity

and the falling block just stays there

not turning into a block

[lost matrix]

Because its not actually there. The client only thinks its there.

The server doesnt know the block exists so it wont turn it into a block.

[regal moat]

oh

so using setMot() would fix it?

[lost matrix]

Nope

[regal moat]

?paste

[undone axle]

https://paste.md-5.net/

[regal moat]

https://paste.md-5.net/cohihebeda.cs

i am currently using this

[lost matrix]

Im also not sure if the packet approach is good here. You should probably just spawn a FallingBlock with velocity turned off and overwritten move() or tick() method to make it teleport to the users crosshair,

[regal moat]

wha

i am pretty new to nms 😅

[lost matrix]

Then this might be a very hard project for you.

[regal moat]

i like to challenge myself though

[regal moat]

what do i have to do here?

[lost matrix]

Eh. You can get creative with this.

Actually spawn the block in or do a bunch of logic yourself.

Spawn the block in and overwrite some stuff so it does what you want it to do idk

[tardy delta]

is there also something to edit the text of an actionbar?

[lost matrix]

What do you mean by "edit"?

[quaint mantle]

hi

[tardy delta]

change the text after it has been sent

like i want to use it to display the health of the player

[lost matrix]

Send a new message

[tardy delta]

ah just a new

[quaint mantle]

i want to change only sword displayname when player pickup it if the sword equals player name
i tried to use this code:

if (item.getType() == Material.DIAMOND_SWORD && item.getItemMeta().hasDisplayName()) {
            if (item.getItemMeta().getDisplayName().contains(event.getPlayer().getName())) {

                event.setCancelled(true);

            } else {
                normal.setDisplayName(ChatAPI.color("&eDiamond Sword"));
            }```

the code works but they don't change item name

if the sword don't equals player name it's change it to &eDiamond Sword

[lost matrix]

More code pls. Do you apply the ItemMeta to the ItemStack again?

[quaint mantle]

else cancel pickup

okay @lost matrix

yes i did

    @EventHandler
    public void onPick(PlayerPickupItemEvent event) {
        ItemStack item = event.getItem().getItemStack();
        ItemStack original = new ItemStack(Material.DIAMOND_SWORD);
        ItemMeta normal = original.getItemMeta();

        original.setItemMeta(normal);
        if (item.getType() == Material.DIAMOND_SWORD && item.getItemMeta().hasDisplayName()) {
            if (item.getItemMeta().getDisplayName().contains(event.getPlayer().getName())) {

                event.setCancelled(true);

            } else {
                normal.setDisplayName(ChatAPI.color("&eDiamond Sword"));
            }
        } else {
            return;
        }
    }```

oh

[tardy delta]

is there something like an .setCollidable(false) in the entitySpawnEvent?

[quaint mantle]

i forget to set item meta?

yes i did 🙂

[tardy delta]

😳

[quaint mantle]

Hello, guys!
I want to modify the BookMeta of a Book and Quill when the player opens it to provide a translated version of a text based on the client's language, but the book UI is first opened and then the Meta modified, no the changes are not noticeable until you reopen the book.

I tried force-closing the book by closing the inventory of the player and then using player.openBook(), but the Material needs to be WRITTEN_BOOK and i need it to be WRITABLE_BOOK.

Any ideas?

[chrome beacon]

Are you spawning the entity?

[tardy delta]

no naturally

[chrome beacon]

Aight dely that with one tick

[tardy delta]

but there is no such method

throws Exception

[quaint mantle]

i just forget to set ItemMeta thx btw ❤️

[chrome beacon]

Check if it's an instance of LivingEntity and cast

[quaint mantle]

last question is there anyway to update scoreboard with out flicker

[young knoll]

Prefix and suffix

[stone sinew]

Was this a response to me?

[rare cave]

try it

[tardy delta]

yes

[stone sinew]

That would require the method to be enclosed in a try catch... which is what I am trying to clean up

[lost matrix]

You want this only for checked exceptions?

[tardy delta]

or let the jvm handle the exceptions

[stone sinew]

yes posted an example of the code it runs in try catch

[rare cave]

its ok to have many try catch blocks

[stone sinew]

I know its ok to lol. But thats not the question

[tardy delta]

still collision..

[lost matrix]

Im this far right now:

@FunctionalInterface
public interface ThrowingConsumer<T, E extends Exception> {

  void accept(T t) throws E;

  static <T> Consumer<T> wrapper(final ThrowingConsumer<T, Exception> throwingConsumer) {
    return value -> {
      try {
        throwingConsumer.accept(value);
      } catch (final Exception ex) {
        throw new RuntimeException(ex);
      }
    };
  }

}

Let me make it a bit more modular...

Wait i should test if this works first...

[tardy delta]

💀

[chrome beacon]

You might need to disable collision for the player too

[tardy delta]

i did

on playerjoin

[lost matrix]

It works:

    final File targetFile = new File("test");
    final YamlConfiguration configuration = YamlConfiguration.loadConfiguration(targetFile);
    ThrowingConsumer.<File>wrapper(configuration::save).accept(targetFile);

[stone sinew]

That alot more code then just try catch though lol.

[rare cave]

hm

[lost matrix]

Its literally just one line

[stone sinew]

yeah I like that. Just thought there was maybe something like as long as a method name.

[regal moat]

@lost matrix i am totally confused with the materials. i can use #getMaterial() but that doesnt return org.bukkit.Material

im confused

[stone sinew]

I'll try to implement it. Thanks

[stone sinew]

I know why I wanted a method now.. I need to do multiple methods in the try catch... load/save/create all in 1 try catch which is why I did runnable

[lost matrix]

You can do all that in a consumer.

  @Override
  public void onEnable() {
    final File targetFile = new File("test");
    final YamlConfiguration configuration = YamlConfiguration.loadConfiguration(targetFile);
    ThrowingConsumer.<File>wrapper(file -> this.doRandomStuffToFile(configuration, file)).accept(targetFile);
  }

  private void doRandomStuffToFile(final YamlConfiguration configuration, final File file) throws Exception {
    // Do a bunch of stuff in here
  }

[tardy delta]

wew

[stone sinew]

Thanks. IDK if this is the route I want though.

wtf is this

[regal moat]

@lost matrix i am totally confused with the materials. i can use #getMaterial() but that doesnt return org.bukkit.Material

help

[quaint mantle]

this is a horrible dependency setup

shame on that developer

[quaint mantle]

code?

[hollow bluff]

I do have the correct repository but it doesnt find the dependency

[quaint mantle]

contact the dev

[fading lake]

does anyone have any idea how you'd go about hosting your maven artefacts on your own site?

[regal moat]

i have a EntityFallingBlock, and i need to get the material out of it

but that returns net.minecraft.world.level.material.Material

and not org.bukkit.Material

[tardy delta]

stupid actionbar doesnt work

[regal moat]

lmao

[regal moat]

@quaint mantle

[fading lake]

Material.valueOf(net.minecraft.world.level.material.Material#name) should work surely

unless the names are differennt

and since NMS Material and Bukkit Material do the same thing, I'd see no reason as to why they'd be different

but theres no direct way to get the bukkit one from the NMS one since bukkit is built on top of NMS, so NMS has no idea bukkit exists, hence it not being able to give an NMS -> Bukkit method

@regal moat

[fading lake]

anything we can help with?

[tardy delta]

uhh this is my code

public class ActionBar extends BukkitRunnable {

    private final Player player;
    private final String text;
    private int start = 0;

    public ActionBar(Player player, String text) {
        this.player = player;
        this.text = text;
    }

    @Override
    public void run() {
        start++;
        Utils.sendActionBar(player, text);
    }
}

and inside the playerjoin i use new ActionBar(p, sometext).run()

[dusk flicker]

Why are you creating an object for it?

[lost matrix]

Dont. You need to schedule this instance using the BukkitScheduler

[fading lake]

Ah, can I see where you attach ActionBar to the scheduler, and show is the code to Utils#sendActionBar

[tardy delta]

public static void sendActionBar(Player player, String message) {
        player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(message));
    }```

[fading lake]

and the scheduler attachment?

[tardy delta]

huuh

[fading lake]

basically wherever you ran ActionBar bar = new ActionBar() you need to put something like Bukkit.getScheduler().runTaskTimer(plugin, () -> bar.run());

[tardy delta]

oh

[lost matrix]

lol...

[tardy delta]

inside that class?

[fading lake]

its one way to do it lmfao

[lost matrix]

Thats like double wrapping

Its already a BukkitRunnable

[fading lake]

I'm half asleep, takeoverpls I can't think straight

but that'd work anyhow

[lost matrix]

new ActionBar().runTaskTimer(plugin, 1, 1);

[quaint mantle]

No

[dusk flicker]

I still think that a object for this is overkill but it works

[tardy delta]

so something like this?

public void run() {
        Bukkit.getScheduler().runTask(Main.getInstance(), () -> Utils.sendActionBar(player, text));
    }

[fading lake]

OH YEAH

no

[tardy delta]

😳

[quaint mantle]

Wtf

[fading lake]

do what smile did

essentially

[quaint mantle]

Then get rid of "extends Runnable" please

[fading lake]

forgot how the scheduler worked for a sec there

the extends runnable is what allows him to attach it to the scheduler in the way he's doing kt

@tardy delta you good now?

[tardy delta]

uhh i'm reading

[lost matrix]

If he does that then he wont be able to schedule it. Extending BukkitRunnable here is correct.

[quaint mantle]

Was replying to an earlier message

I blame my highly unstable net

[tardy delta]

and why not runTask() instead of timer?

to wait one tick?

[dusk flicker]

I believe the idea here is to make it go on for a set amount of time

[regal moat]

that gives out an error. but Material.valueOf(String.valueOf(fallingBlock.getBlock().getMaterial())) doesnt

[ivory sleet]

Wth

[regal moat]

i have no idea

[ivory sleet]

Hmm yeah I can tell

[regal moat]

what can i do

in this situation

[ivory sleet]

What are you trying to do?

[fading lake]

does it work though 👀

[ivory sleet]

No it won’t

Unless Material::toString calls Material::name

[quaint mantle]

Unless the Enum member declarations Match up

By default it should (for toString = Name)

[fading lake]

afaik, all enums toString return the name?

[ivory sleet]

Yeah Idk if it’s overridden or something

[fading lake]

at least they always have for me

oh possibly

[quaint mantle]

ToString can be overriden

Name cannot

[fading lake]

whats the error when you try to use name?

[ivory sleet]

I thought any derivative of the Enum class by default just returns its garbage value

[fading lake]

yeah, but I dont see why it would be, its worth checking though

[quaint mantle]

Lemme see

[fading lake]

I'd be able to test it but I'm not at my PC

[quaint mantle]

No https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/lang/Enum.java#L150

[ivory sleet]

Hmm alright good to know

[regal moat]

Provided: Material```

@fading lake

[quaint mantle]

Enum#name ALWAYS returns String

[regal moat]

i am using intellij

[fading lake]

Material#name doesnt return Material

[quaint mantle]

Then fuck IJ - though I think you Just plainly messed up

[regal moat]

so what should i do here

[quaint mantle]

Make Sure you call .name

[fading lake]

could you take a screenshot of the error?

and what the code is causing it?

[quaint mantle]

(is NMS Material even an Enum?)

[fading lake]

oh that could be it

uh oh

[quaint mantle]

?stash

[undone axle]

https://hub.spigotmc.org/stash/

It isn't

Nms has moved away from enum representation for a while

[fading lake]

whats the point in that

[quaint mantle]

Mods

[fading lake]

?

why cant mods use enums

[quaint mantle]

Converting enums into registries is a PITA

[fading lake]

sorry, whats a PITA

[quaint mantle]

Especially If you have the kind of insanity that the Bukkit Material Enum has

Pain in the ass

[fading lake]

ah

not me googling it and it returning results for pita bread

Hello! I have a problem with my local maven repo, after built BuildTools. That is, when I add as a dependency in IntelliJ(as a library), I can't see its commets. Just like it make library file simply small and has no comment, and some of variable show only var0, var1, var2, etc. It is hard to read and follow the library. How to deal with that?

Here is example:

• original: https://ibb.co/K0YmkcH

[eternal oxide]

did you add javadocs to your pom?

[rigid otter]

• what I see in IntelliJ: https://ibb.co/DY7ZshB

[ivory sleet]

Yeah

[quaint mantle]

@fading lake

[ivory sleet]

You’re depending on a decompiled jar just like that? Not a maven artifact dependency or anything like that.

You probably want to add the respective sources jar to your classpath

[rigid otter]

Ohh

[fading lake]

player.setExp(Math.max(0, player.getExp() - сумма чтобы взять));

So we need to add a sources jar to the classpath which contains all the classes from the dependency but not compiled to class files (they’re still .java files)

потому что вы берете больше опыта, чем у них

[rigid otter]

For me, I don't have that javadoc, just jar

[quaint mantle]

no

[eternal oxide]

add it and it will be pulled from the spigot repo

[rigid otter]

Then it show an error

And library is lost

[fading lake]

ошибка говорила, что вы пытались установить их опыт на -1394.0625

[eternal oxide]

did you fill in the version?

[rigid otter]

Filled

[quaint mantle]

Yes, I have level 40

[eternal oxide]

it works fine, you have to have one for the spigot-api and one for the javadocs

[rustic gale]

so how do i make it so when i change PlayerGuilds of an instance, the original player guilds also change? also ty for the uuid tip ill change it rn

[fading lake]

пытаться player. setTotalExperience(Math.max(0, player.getTotalExperience() - сумма чтобы взять));

[vale ember]

please help, i need to replace all '&#(a-fA-F0-9)' with ChatColor.of("#(a-fA-F0-9)")

[rigid otter]

It still doesn't work for me

[eternal oxide]

What isn't working about it?

[rigid otter]

Still the same as before

[eternal oxide]

have you manually added some other jars?

[rigid otter]

What others?

[quaint mantle]

this simply resets the experience scale

[eternal oxide]

It works perfectly if you've not added somethign manually ```java
/**

• Represents a player, connected or not
  */
  public interface Player extends HumanEntity, Conversable, OfflinePlayer, PluginMessageRecipient {

  /**

  • Gets the "friendly" name to display of this player. This may include
  • color.
  • <p>
  • Note that this name will not be displayed in game, only in chat and
  • places defined by plugins.
  • @return the friendly name
    */
    @NotNull
    public String getDisplayName();```

that is what I see for Player

[rigid otter]

Yeah, for me don't😔

what is the type of a function function or whatever is used in java for callbacks? specifically o want to send a lambda expression to a function to call when finishing something

[quaint mantle]

how to take experience from players?

[rigid otter]

Only this

        <dependency>

Consumer<T> for defining functionality for later usage.
Callbacks should be done using CompletableFutures or the Future API in general.

[fading lake]

что показывает player.getTotalExperience() - сумма чтобы взять

[eternal oxide]

Thats all that is in your pom. You have something else as you showed us a screen of some decompiled jar

[lost matrix]

Add negative experience

[lost matrix]

total experience is just for statistical purpose

[rigid otter]

What do you really mean?

[quaint mantle]

it doesn't work, it lowers the level, but it doesn't show. as a result, the bug is broken and it will no longer be possible to issue a level

[eternal oxide]

Your first and second screenshot you showed us

What IDE are you using?

[rigid otter]

I'm using IntelliJ

do all the dependencies show as fine in Intelij? No red underscores
