What

[reef wind]

so you are putting in the jar and then reloading/restarting?

and nothing happens

[quaint mantle]

show your exported jar in the plugins folder

🤸 🏌️

🦽

[reef wind]

I just need to ask in case you are stupid, you are reloading/restarting the server right?

[woeful prawn]

Does anyone know how I can make an itemstack where the item (say a wooden pickaxe) has the nbt tag "canBreak ___" in spigot?

[quaint mantle]

search spigot nbt api

[reef wind]

?google

[undone axle]

Google your question before asking it:
https://www.google.com/

[woeful prawn]

I did, like for the past like hour

and I couldn't find anything, so I thought I'd ask

[reef wind]

I found it 1st result

[quaint mantle]

.

it has to be .jar

[reef wind]

I doubt that (first result) https://www.spigotmc.org/threads/tutorial-the-complete-guide-to-itemstack-nbttags-attributes.131458/

[quaint mantle]

why tf is it uppercase

in spigot it does apparently

[hasty prawn]

Clearly it does

[reef wind]

lmao

[willow widget]

Hey, I used to follow a tutorial that used

onCommand(I dont remember this part){
  if(label.equalsIgnoreCase("mycommand")){
//  do something
  }
}

After learning some other things non spigot related I wonder if this is the right way to write the code for a command (i.e. the right way when talking about api docs), can someone confirm? (:

[quaint mantle]

correct

[quaint mantle]

no

setting the command executor removes that if statement

getCommand("hi").setExecutor(new MyCommand());

[woeful prawn]

Glad that was you first result, my many results led me down this rabbit hole:
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/ItemStack.html
https://www.spigotmc.org/threads/play-effect-block-break-with-itemstack.382802/
https://bukkit.org/threads/setting-item-durability.351123/
https://hypixel.net/threads/bukkit-spigot-adding-and-checking-for-nbt-tags-on-items.383877/
... and more
(a list of a few of my tabs so far)

[willow widget]

I was about to ask that lol

[quaint mantle]

codedred right?

[willow widget]

then MyCommand()is what the command is gonna do?

[reef wind]

next time search "x spigot"

[willow widget]

yup lol

[quaint mantle]

he promotes bad practices and shit code

[reef wind]

youtube videos are a shit way to learn

[quaint mantle]

but sometimes hes useful

google > youtube

docs > youtube

[woeful prawn]

Thanks for tip, that is not what i searched, I don't remember exactly, but it was something along the lines of "spigot java x"

[willow widget]

Yeah, for what I've read/learnt/everything tutorials are bad bc of bad practices and other stuff

[reef wind]

youtube videos teaches bad practice they are a lot of the times outdated and they usually don't even know what they are doing.

[willow widget]

I was new to coding overall when I saw those vids so I didn't know how to read docs at all lol

[reef wind]

using docs and google is the only option

[willow widget]

mhm, they also have their own coding style and other stuff which is personal but try to teach as a lesson sometimes

[reef wind]

change api in yml to 1.17

[quaint mantle]

then you have a startup error

[reef wind]

the latest api is for 1.17 (but works for 1.17.1)

[quaint mantle]

major.minor

[willow widget]

When making a command this way how do I pass the same args used in onCommand()?

I mean... how'd I get the sender and that stuff? ||(again... I'm kinda rusty so I don't remember how it worked hehe)||

[reef wind]

? what imagine provided just makes the command execute that, you don't need to provide arguments there.

/command(hello) args(..)

the arguments is not the command (if I understand you correctly)

[willow widget]

Then how'd the MyCommand method be written to get the sender and args?

[reef wind]

if I make the command "hi <x>" respond with x I just pass "hi" in getcommand

[willow widget]

I mean...
when you use onCommand() you get the (label, sender, args, etc) stuff, how do I code that part when using .setExecutor(new MyCommand());?

[reef wind]

not the arguments

[reef wind]

what are you talking about?

[willow widget]

aaaaaa

I'm just trying to figure how to get the sender and args lol

oh wait

MyCommand() is a class which extends something to get all the args and stuff??

[reef wind]

Command

 public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        
        sender.sendMessage(args[0]);
}

Main

this.getCommand("command").setExecutor(new ClassName());

that is an example of how it would look

[willow widget]

yeah but where is that ReloadConfig() part? xd
I just don't completely understand that, but I think ReloadConfig() is a class and the onCommand() is inside that class?

that kinda sounds like an enemy more than a friend hehe

[reef wind]

the class

[willow widget]

so yeah... that's the class and the onCommand() is inside that class?

[reef wind]

yes.. methods goes in classes..

[willow widget]

yeah... I was used to do onCommand() inside my main class, that's why I was confused lol

[reef wind]

that will make your main file gigantic and a mess, don't do that.

how do you even manage that? skript is like plaing english.

no

just use getCommand()

getCommand().setExecutor() will execute the command

[willow widget]

Yeah that's why I'm asking all of this hahaha

[reef wind]

use this for your commands

what are you on?

just set the executor in main and make aliases in plugin.yml

you don't need some custom command handler

[quaint mantle]

/ConstantConditions/

[vast sapphire]

I don't know how to work with configs that well

How would I write a hash map to the config

[native nexus]

ConfigSections work similar to hash maps in theory

[stone sinew]

Using bukkit serialization...

Map.entrySet().forEach(entry -> {
    String s = entry.getKey();
    Location l = entry.getValue();
    config.set(s, l);
});
saveConfig();

A bit cleaner but more methods to make your own seralization.

// Save to config
public Location stringToLocation(String s) {
    String[] data = s.split(",");
    if(data.length < 4) return null;
        
    Location loc = new Location(Bukkit.getWorld(data[0]), Double.valueOf(data[1]), Double.valueOf(data[2]), Double.valueOf(data[3]));
    if(data.length == 5)
        loc.setYaw(Float.valueOf(data[4]));
    if(data.length == 6)
        loc.setPitch(Float.valueOf(data[5]));
    return loc;
}
    
public String locationToString(Location l) {
    return l.getWorld().getName()+","+l.getX()+","+l.getY()+","+l.getZ()+","+l.getYaw()+","+l.getPitch();
}

Map.entrySet().forEach(entry -> {
    String s = entry.getKey();
    config.set(s, locationToString(entry.getValue()));
});
saveConfig()

// get from config...
ConfigurationSection cs = YamlConfiguration.getConfigurationSection("");
cs.getKeys(false).forEach(path -> map.put(path, stringToLocation(cs.getString(path))));

[native nexus]

private final Map<String, Integer> data = new HashMap<>();

public void deserialize(FileConfiguration configuration) {
    ConfigurationSection section = configuration.getConfigurationSection("data");
    if(section != null) {
        for(String key : section.getKeys(false)) {
            data.put(key, configuration.getInt("data." + key));
        }
    }
}

public void serialize(FileConfiguration configuration) {
    for(Map.Entry<String, Integer> entry : data.entrySet()) {
        configuration.set("data." + entry.getKey(), entry.getValue());
    }
    // Save Config here with (saveConfig() or custom config)
}
``` Simpler example

[stone sinew]

read the top half of my message lol

[ionic dagger]

Would a 1.15 plugin coding tutorial work for 1.16

Or are there major differences between the two versions

[vast sapphire]

Thanks, i'll try it

[quaint mantle]

public Location deserialize(ConfigurationSection cs, String path) {
    if (cs.getLocation(path) != null) {
        return cs.getLocation(path);
    }
    return new Location(
        cs.getInt(path + ".x"),
        cs.getInt(path + ".y"),
        cs.getInt(path + ".z")
    );
}

[stone sinew]

Shouldn't be any different besides added nether materials

[ionic dagger]

What abt 1,17

[stone sinew]

No world?

[stone sinew]

I've seen no difference aside from needing to change to java 16 to run the server

[vast sapphire]

ConfigurationSection cs = ConfigurationSection.get("locations"); Non-static method 'get(java.lang.String)' cannot be referenced from a static context

[ivory sleet]

The api is generally made to support older and newer versions tho with that being said there’s no guarantee

[stone sinew]

ConfigurationSection cs = YamlConfiguration.getConfigurationSection("") change yamlconfig to what ever your yaml variable is.

[reef wind]

don’t watch YouTube tutorials

[ionic dagger]

So what do u suggest

[reef wind]

docs and google

[native nexus]

You get it from a FileConfiguration

[reef wind]

@ionic dagger

learning from videos is not an option

[ionic dagger]

I was just gonna use codedreds 1.15 vids as an intro and use my Java class in school to continue it

[ivory sleet]

I’d argue for that YouTube tutorials can be good as they might show a concrete way of addressing a problem however 99% of the YouTube tutorials miss a good solid code architecture, so yeah rather just understand the concept than copy pasting.

[native nexus]

Wait... is that a capitalized Variable...

[stone sinew]

Depends what he is using... He might be using YamlConfiguration he might be using FileConfiguration

[reef wind]

definitely not him

He teaches bad practice just like imagine said

Like I said earlier

youtube videos teaches bad practice they are a lot of the times outdated and they usually don't even know what they are doing. +they take more time to follow

[ivory sleet]

@ionic dagger do you have Java experience which is not directly derived from spigot related sources?

[vast sapphire]

so from what i'm understanding, this goes into onEnable() ```java
hash.entrySet().forEach(entry -> {
String s = entry.getKey();
getConfig().set(s, locationToString(entry.getValue()));
});
saveConfig();

    // get from config...
    ConfigurationSection cs = getConfig().getConfigurationSection("locations");
    Objects.requireNonNull(cs).getKeys(false).forEach(path -> hash.put(path, stringToLocation(Objects.requireNonNull(cs.getString(path)))));

        hash.entrySet().forEach(entry -> {
            String s = entry.getKey();
            Location l = entry.getValue();
            getConfig().set(s, l);
        });```

[reef wind]

thanks for blocking my view

[stone sinew]

Only need

ConfigurationSection cs = getConfig().getConfigurationSection("locations");
cs.getKeys(false).forEach(path -> hash.put(path, stringToLocation(cs.getString(path))));
``` in onEnable because thats when you're loading from the config.

[stone sinew]

Make sure to read my message cause it looks like you just copied and pasted everything lol

[ionic dagger]

I took an intro to Java last year, and before that I was doin vbnet and py

[stone sinew]

There are 2 different ways of loading and saving data in that message.

[ivory sleet]

Interesting, what level are you at would you say?

[ionic dagger]

For Java? Not too high, I forgot most of it since I went back to py over the summer

[ivory sleet]

Ah fair

Py’s object orientation is a bit too hacky imo

[native nexus]

I don't like python

[ionic dagger]

Me neither

It was weird to me

My teacher taught it weird

But do you have any links then for any docs or really anything I can use instead of the videos

[native nexus]

Universities are just bad at teaching programming languages.

[ivory sleet]

for Java

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[ivory sleet]

If you understand Java

?jd-s will get you going

[ionic dagger]

Thank you

[quasi stratus]

How would one make a message hoverable/clickable in chat? java player.sendMessage(ChatColor.translateAlternateColorCodes('&', "&r &e* &bUser Agreement"));

[stone sinew]

Anyone know if there is a way to disable the world loading messages in console? Like Bukkit.getWorld("WorldName", boolean displayMessages) (just example usage)

[native nexus]

https://www.spigotmc.org/wiki/the-chat-component-api/

[vast sapphire]

I copied over the method approach, do I put locationtostring where I want to add the location?

[stone sinew]

yes

[quaint mantle]

you can always catch sysout

hacky, but works

[stone sinew]

was hoping not to have to.

[quaint mantle]

try looking at stash

see what getworld calls

?stash

[undone axle]

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

[stone sinew]

it calls server.getWorld() But I'm only finding the interface class of Server

[ivory sleet]

Check CraftServer in CraftBukkit

[stone sinew]

Yeah checking it

[quaint mantle]

Im getting this error at

player.setPlayerListHeaderFooter(String.valueOf(new ComponentBuilder(bleepo.parseText(player, head.toString())).create()), new ComponentBuilder(bleepo.parseText(player, footer.toString())).toString());

And Im not sure why. anyone know?

[stone sinew]

private final Map<String, World> worlds;
public World getWorld(String name) {
    Validate.notNull(name, "Name cannot be null");
    return (World)this.worlds.get(name.toLowerCase(Locale.ENGLISH));
}
```Not seeing where it creates a world from `Bukkit.getWorld(String)`

[ivory sleet]

The same

It’s the CraftServer

Spigot uses Bukkit.setServer(server)

[stone sinew]

No I'm saying that method doesn't create a world... so I think I'm missing something...

All I found was
Bukkit.getWorld(String) -> server.getWorld(String) -> (World)this.worlds.get(name.toLowerCase(Locale.ENGLISH));
Where is the world created if its not cached?

[vast sapphire]

one more question, do I put this also where I want to define the location? I did that and it only spawns items 1 gen at a time.

                                        hash.entrySet().forEach(entry -> {
                                            String s = entry.getKey();
                                            Location l = entry.getValue();
                                            getConfig().set(s, l);
                                        });```

[stone sinew]

you should put it in onDisable

[stone sinew]

but modify it to use the correct methods.

[vast sapphire]

alright, config still looking like this ```yaml
locations: {}

[stone sinew]

if you are using the code above its because you are not setting it to locations path.

[vast sapphire]

I did here java ConfigurationSection cs = getConfig().getConfigurationSection("locations");

[stone sinew]

public void onDisable() {
    hash.entrySet().forEach(entry -> {
        String s = entry.getKey();
        Location l = entry.getValue();
        getConfig().set("locations."+s, locationToString(l));
    });
    saveConfig();
}

[quasi stratus]

                TextComponent user_agreement = new TextComponent(ChatColor.translateAlternateColorCodes('&', "&r     &e* &bUser Agreement"));
                user_agreement.setClickEvent(new ClickEvent(ClickEvent.Action.OPEN_URL, "https://bit.ly/halara-rules"));
                user_agreement.setHoverEvent(new HoverEvent(HoverEvent.Action.SHOW_TEXT, new Text("Click to view the User Agreement.")));
``` I apologize in advance I'm very new to this but I have no idea what i'm doing wrong here. No errors and the text simply does not appear in chat.

[stone sinew]

Where is the rest?

[quasi stratus]

I didnt send it to the user did i

[stone sinew]

Sending the message etc...

[quasi stratus]

I sure did apologize in advance lol thank you that solved it

[stone sinew]

👍

[stone sinew]

Any ideas? #help-development message

[native nexus]

Are you trying to create a world?

[quaint mantle]

Yo yapperyapps you got any clue?

[ivory sleet]

Can you rephrase?

[stone sinew]

Yeah I'm creating a world using Bukkit.getWorld() but based on the code I can't find where it actually creates the world.

[ivory sleet]

WordCreator

[hasty prawn]

As yes, love the WordCreator class

[stone sinew]

java.lang.NoSuchMethodError: 'void org.bukkit.entity.Player.setPlayerListHeaderFooter(java.lang.String, java.lang.String)'

[stone sinew]

Yeah I checked there but as I look through Bukkit.getWorld() it only calls what I show in that message...
Bukkit.getWorld(String) -> server.getWorld(String) -> (World)this.worlds.get(name.toLowerCase(Locale.ENGLISH));

[ivory sleet]

Yea

It’s a query method

Not a command method

[stone sinew]

So where does it get called from??? thats what I am looking for lol

[ivory sleet]

it?

[stone sinew]

sigh If I run Bukkit.getWorld(String) it runs return server.getWorld(String) and that returns return (World)this.worlds.get(name.toLowerCase(Locale.ENGLISH)); but no where through these methods is WorldCreator called

[ivory sleet]

No

It’s a getter

Not a loader

Not a command method

Not a creator

It is just querying the map

WorldCreator has the logic of adding stuff to the map

A function should only do one thing

[peak depot]

whats the problem

[stone sinew]

Ok.................................. IDK how else to explain the question...

If I run Bukkit.getWorld(String) where in the fuck is it calling WorldCreator because thats what I want to access to see if I can tell it not to send the world creation messages.

[ivory sleet]

It’s not calling WorldCreator

[stone sinew]

Exactly!

[ivory sleet]

That’s done somewhere completely else

[stone sinew]

Exactly!!!!!

[ivory sleet]

Because that’s not what it’s meant for

Jfc

[stone sinew]

So fucking where is it being ran!

[ivory sleet]

During the bootstrap process?

[stone sinew]

Is it accessible via the api or would I have to find my own way?

[stone sinew]

If this is the case might as well just remove from syst out

[ivory sleet]

Wym by accessible? There’s a maximum of three worlds that loads everytime the server bootstraps which is the default ones. iirc they’re loaded in CraftServer or if it was MinecraftServer or one of its derivatives. I don’t know where exactly because it goes extremely deep down. However the worlds are loaded at the time your JavaPlugin::onEnable is invoked if that’s what you mean by accessible.

[stone sinew]

I load a world via Bukkit.getWorld(String) that causes the console to output the world settings... I don't want the world settings to show in console

[peak depot]

like for what you need to even do this

[stone sinew]

not need, want.

[peak depot]

no like whats the pupurpose

[ivory sleet]

What’s the map implementation of that Map<String,World> worlds field

[stone sinew]

Was hoping I didn't have to listen to system out to clear it. Its purpose is because I don't want to see it ever time I start my server every 10 seconds.

[native nexus]

You could try log4j filter

[ivory sleet]

Oh at the start

[quaint mantle]

you can always disable it in bukkit.yml

[ivory sleet]

That’s not the implementation

That’s the field

Anyways imaginedev probably got your answer

[stone sinew]

Where?

Not seeing any paths relevant to logged world settings

[quaint mantle]

Ive tried everything that i thought may be wrong, And i still havent fixed it

i think its like debug-log: false

[ivory sleet]

Is the server version the same as you compile against

[vast sapphire]

@stone sinew when you're not busy, I am still in need of help here, I don't know how to save the locations to the config and the config only contains locations: {} https://paste.md-5.net/nivebasawa.java
Thanks for all of your help so far though.

[stone sinew]

Why do you keep adding Objects.requireNonNull(?

[vast sapphire]

to stop a nullpointerexception

[ivory sleet]

It doesn’t stop it

[stone sinew]

^^^

[ivory sleet]

It just re throws it actually despite the name

[stone sinew]

And since you are looping through the entry set it wouldn't be null unless you somehow added a null

[quaint mantle]

nullableValue;

if nullableValue == null: throw NPE

[vast sapphire]

ok

[stone sinew]

Also you are saving the config loading the hashmap then saving again, then loading the config....

And you are always copying defaults in your loadConfig

[stone sinew]

spigot.yml, server.properties and bukkit.yml all have any "debug" paths as false.

[vast sapphire]

ok now I save it after, i removed the extra saveConfig();

[stone sinew]

You are reading from a config you don't need to save it in onEnable (Unless you are loading its defaults)

[vast sapphire]

ok

[stone sinew]

public void onEnable() {
    ConfigurationSection cs = getConfig().getConfigurationSection("locations");
    cs.getKeys(false).forEach(path -> hash.put(path, stringToLocation(cs.getString(path))));
}

public void onDisable() {
    hash.entrySet().forEach(entry -> getConfig().set("locations."+entry.getKey(), locationToString(entry.getValue())));
    saveConfig();
}

I edited my message. You don't use "locations." in cs.getString() because its already in the configurationsection

[vast sapphire]

nothing is going into the config now

[vast sapphire]

same thing ```yaml
locations: {}

[stone sinew]

Let me see your updated code

[vast sapphire]

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

[stone sinew]

You are still copying defaults and then saving the config... you need to check if they are set already

[native nexus]

You just need to do saveDefaultConfig(); before you load anything.

[vast sapphire]

I did that

[vast sapphire]

nothing is in the config now

[hasty prawn]

So I'm having a really weird issue with a resource pack. I'm generating all the JSON files and such in code for the pack, and then zipping it and it can be immediately applied, or atleast in concept.

Although something seems to go really wrong when I zip it. It just will not apply the textures properly right out of the box. If I unzip the generated zip, everything works flawlessly, and if I re-zip the folder using just the standard Windows Send To ->, it still works.

I also know that Minecraft is able to atleast open the generated zip file, since it can still apply it, and the pack.png is properly set.

The zipped file sizes between the Generated and Windows are different too, with the only difference being that one of the JSON files is slightly larger in the Windows zipped folder.

This is how I'm zipping the resources https://paste.md-5.net/cugiduxava.java

[vast sapphire]

actually I got this ```yaml
locations: {}

[native nexus]

Is your map empty...?

Once you save it?

locations: {} normally means that yaml is aware that is is a collection of some sort.

[timber whale]

How do i check if a player has armor on

[quaint mantle]

how can I replace an object with another one for a few seconds when clicked in the GUI?

[native nexus]

Does anyone recommend using Guava Cache or is it quite hefty for Minecraft Servers?

I would rather have a simple library or class that can handle cache efficiently.

[lost matrix]

I would recommend Caffeine instead. Its from the guy that wrote the cache stuff for guava.
If you know what you are doing then such a cache can really help with the reactiveness of your
database access.

[native nexus]

Yeah just whenever I want to access my cache I was entries that are older than 5 minutes to be cleared.

[lost matrix]

Thats a really short period for a cache...

[native nexus]

Yeah I am doing pagination for an inventory.

What would you recommend normal periods to be?

[lost matrix]

Depends a bit on the data you want to cache and how high your request frequency is. But for offline player data i would go for at least 45 - 60m

Usually you want to keep most of your data in your cache. Only really old data that doesnt get accessed anymore should be kept out of it.
Even if you keep data of 10k users in cache, its size probably wont exceed 50 - 100MB. And who hasnt that much memory to spare.

[lost matrix]

Get his Equipment and check if every entry is null

[lost matrix]

Using a scheduler that replaces the object later again.

[earnest spear]

help me

plz

:<

[lost matrix]

Re-install mcdev

[earnest spear]

I have did the following things :-

1. Restarted intellij
2. reinstalled intellij and all plugins
3. Restarted my pc
   nothing helps :<

am gonna die fixing it

help save my life

[lost matrix]

The minecraft versions are retrieved via the internet. Maybe you have a firewall that blocks the fetching of those versions.

[earnest spear]

this?

[lost matrix]

idk. Some firewall.

[earnest spear]

McAfee

I have the McAfee firewall

[lost matrix]

Disable your firewalls for a min and then re-try

[earnest spear]

ok

[lost matrix]

Also if you can get a grasp of the error somehow then we know for sure.

[earnest spear]

It didnt work

still the same error

[lost matrix]

Try getting us the error. There must be a log somewhere.

[earnest spear]

Cant find anything

[lost matrix]

Did you find the log?

[earnest spear]

no

[lost matrix]

Do you have a project named Heart2 ?
Because this one causes a ton of errors.

[earnest spear]

yeah

[lost matrix]

Delete it from your IDEs view and copy the folder somewhere else.

[earnest spear]

ok

[quaint mantle]

Umm the website is not working properly, I just posted an update for my plugin and its not showing it and when I download its downloading older version.

[quaint mantle]

how can I stop the scheduler after replacing the item?

[lost matrix]

Just schedule it once. runTaskLater()

[quaint mantle]

how can this be done? and if I use the replacement again, will it work?

[rustic gale]

Why doesn't this runnable run? (i feel theres a super stupid mistake, I barely understand runnables)

Also this runnable is in my main classs

[vague oracle]

Try waiting 1 tick

[paper geyser]

whats an efficient way of checking when a player enters an area? I've thought of like on move, check if they're in an area but theres probably more efficient ways right?

[lost matrix]

If your check is really fast then on move is fine. If you plan on supporting a lot of players and willing to sacrifice some precision then you can also do distributed scheduling.

[lost matrix]

This should run. Did you properly export the jar? Does it show up when calling /pl ?

[rustic gale]

ill try rn

and i think i properly exported it

I just Built the artifact

in intillej

[lost matrix]

/pl

[rustic gale]

alr i will try the second my server restarts

yeah my plugin is there

oh wait im so stupid

[lost matrix]

plugin.yml?

[rustic gale]

i was doing this thru the console

so no players were online

[lost matrix]

...

[rustic gale]

welp

uh

sorry

alr yeah it works

interestly though it didn't work if there wasn't the 1 tick delay

ty for the help

[fluid cypress]

is there any extension/plugin or something for itellij that do stuff about minecraft plugins? for example, telling me when im not declaring a command in plugin.yml, with code snipets of api things, like a class that implements CommandExecutor or some other interface, or to be able create the "a minecraft project" with spigot/paper as dependency, and the package and the main class created already created? extending from JavaPlugin and all that stuff

and another thing that idr if i already asked, I guess i did but idk, do i really, even today, 2021, have to restart the server every time i make a minor change to a plugin? or is there a way i can my a plugin "reload safe"?

i mean, i know that using /reload in "production" is bad, but when developing too? do you all restart your servers bc of a typo in a string?

[eternal oxide]

yes

[fluid cypress]

what about the extension/plugin for intellij

[eternal oxide]

There is an extension to help creating plugins, but I'd never recommend it.

Learning how to do things yourself improves your skills.

[fluid cypress]

dont you use any extension? or did you create your own snippets or something

[eternal oxide]

and once you have learnt it take but a couple of minutes to throw a basic plugin framework together

I use Eclipse. No extensions nor code suggestions.

[native nexus]

@fluid cypress Yes there is I am using it right now

[fluid cypress]

how is it called

[lost matrix]

minecraft dev plugin

[native nexus]

You can search for the plugin in IntelliJ

[lost matrix]

But what you described sounds more like you want to write a custom sonar rule checker for yourself.
Regarding the restarts: You can set up your dev environment allowing hot swapping. So making minor changes will be seen live without reloads needed.

[fluid cypress]

im using it, and since i installed it, it no longer tells me that the plugin class is not being used or that event listener methods are never called, which is good, but it does nothing about undeclared commands in plugin.yml. it wouldnt be too do that, and i would avoid having to use Objects.requireNonNull and some server restarts

[lost matrix]

The mc dev plugin mainly helps you set up a project with all dependencies and a plugin.yml including a main class which extends JavaPlugin already.

[fluid cypress]

yea, i have to see about that

[fluid cypress]

what do you mean with "allowing hot swapping"

you mean using a config or something

[quaint mantle]

how do I check if the inventory is full?

[lost matrix]

Hot swapping means you can program and see your changes right there in the running server without having to stop it.

[quaint mantle]

@lost matrix

how do I check if the inventory is full?

[lost matrix]

I dont think you want to check if an Inventory is full. You would rather know if a certain ItemStack can fit in the Inventory, right?

[quaint mantle]

yes

[fluid cypress]

i have never heard of that, is that a java thing? or an intellij thing

[quaint mantle]

I need to place an item in the inventory and if there is no space in the inventory, do not place it. if there is the same item in the inventory, put

[fluid cypress]

using the debugger, right?

[lost matrix]

Thats a java thing. Not very common and has some limitations. Its only useful for minor changes.

[lost matrix]

Are you fine with adding items and dropping those that dont fit on the ground? Because thats the cheapest way of handling inventory overflow.

[quaint mantle]

no

[lost matrix]

Then there are 2 approaches:
Lazy but more expensive: Clone the inventory and check if it overflows when you add an ItemStack
Labour intensive, complicated and error prone but possibly cheaper: Write your own method that iterates over the entire Inventory and keeps track of how much you could theoretically fit into the inventory.

[quaint mantle]

Check if inventory contains air

на русском пиши)

[lost matrix]

No

[quaint mantle]

Why no

[eternal oxide]

Inventory#addItem returns a Map of anything that won;t fit.

[quaint mantle]

Потом

Ah ya

You can

[lost matrix]

1. It might just contain a slot that is null
2. There could be a stack of that type which could still fit the items he is about to add

[shut plaza]

main: com.minco.plugin.mplg.Main
name: MyPlugin
version: 1.0
author: me
description: "An Example plugin"
commands:
    ping:
        description: "Ping Pong"

Why not working? (1.17.1)

[quaint mantle]

L

[lost matrix]

But it adds the items already. And reverting that is not really possible.

[eternal oxide]

doe he need to revert?

[lost matrix]

He wants to not add the items if they dont fit completely

[eternal oxide]

ah

[shut plaza]

h e l p

[lost matrix]

Honestly there should be a method for that in Inventory like Inventory#canFit(ItemStack...)

[eternal oxide]

I'd probably go with the addItem (one stack at a time). If they don;t fit, take the returned from what you wanted to add, then remove what was added.

[lost matrix]

What does the console show if you try to start with your plugin installed?

[shut plaza]

eclipse

[lost matrix]

Sounds ew.

[eternal oxide]

probably easier than checking for space

[lost matrix]

I would just clone the inventory, add the items and see if there is overflow. Then return true or false.
Thats the lazy way of checking if an Inventory can fit certain items.

[quaint mantle]

I'm using that

[quaint mantle]

это что?

[eternal oxide]

I guess, so long as you are not doing it often

[quaint mantle]

🤦

[lost matrix]

Yeah but he doesnt want to drop the items on the ground

[quaint mantle]

No, he can delete dropItemNat ..

[quaint mantle]

можно позвонить?

Just for

[quaint mantle]

Nah

сказать, что именно нужно

Text

[lost matrix]

But then he possibly deletes one half and just deletes the other half. Thats stupid.

Then you dont need to drop them in the first place lol

[quaint mantle]

No

Sec

[lost matrix]

Oh you mean in the pickup event

[quaint mantle]

I have all the resources placed in the chest, if there is no place there, they are thrown next to the entity

[lost matrix]

I think he doesnt want that

[quaint mantle]

I showed him just a for

that is, how to get those elements that did not fit into the inventory

I need to check if there is no space in the inventory but there is the same item that I want to add, add it. if there is no such item and the inventory is full, do nothing

Мне нужно проверить, нет ли места в инвентаре, но есть тот же товар, который я хочу добавить, добавьте его. если такого товара нет и инвентарь заполнен, ничего не предпринимайте

Inside my for , just set item.remove();

See if your plugin.yml got exported with the jar. You can just open it with 7zip

if plugin.yml had not been exported, there would have been another error

That is literally not what he wants.

Like Invalid Plugin.yml

[quaint mantle]

He said me in our lang

@lost matrix

how to do it?

Learn java

[shut plaza]

yes

[lost matrix]

You need to write a method for that. Its a bit complicated, logic wise. Give it a try and if you dont figure it out ill provide you with some help.

[quaint mantle]

and what's the problem?

I said him using Visual Bukkit, cuz he don't know Java, and he don't want learn java

||(https://www.spigotmc.org/resources/visual-bukkit.76474/)||

[lost matrix]

That would be ambiguous behavior. Does the client need both permissions? Does he only need one of those two?

[lost matrix]

I would rather just not work with plugins than using this kind of garbage.

[quaint mantle]

I started writing plugins for Minecraft with Visual Bukkit

¯\_(ツ)_/¯

[lost matrix]

Im actually not sure. The only reason could be that your installed jar does not contain the content you provided us with.

[quaint mantle]

so I don't think that this is garbage, for beginners it will go just right

[lost matrix]

Probably

[quaint mantle]

✌️

[lost matrix]

Compile again and make sure that your newest plugin version is in the plugins folder. Then open the jar and look inside the plugin.yml to make sure the command is actually in there.

where to find the item names for different color wool in 1.8

Hm. I guess you could send players different Advancements packets based on certain conditions when they join. The client asks the server what types of advancements are active.

the nbames from 1.17 no work

[lost matrix]

Deep in the archives of some forum posts or very old javadocs. 1.8 support was dropped over half a decade ago. Update.

Ive given you all the infos you need.
You need to iterate over the inventories content and count up the amount of items you can fit in there by
either checking if the slot is null or if the ItemStack isSimilar and still has space.

You wont get more than this:

    final int amountToAdd = itemStack.getAmount();
    final int spaceForItem = 0;
    final int maxStackSize = itemStack.getType().getMaxStackSize();

    return false;

okay, thanks

[quaint mantle]

can I have a little more?)

🤦

ya dolboeb

Of course

[lost matrix]

Nope.
Check if the slot item is null or air -> then add the maxStackSize to spaceForItem
else -> Check if slotItem is similar to itemStack -> then add the (maxStackSize - slotItem.getAmount()) to spaceForItem
Return true if spaceForItem is bigger than amountToAdd

oh was it broken for a version?

hm

let me check

[lost matrix]

No idea.

[tawdry cedar]

I think you just have to remove people from the bossbar

Not entirely sure though

But try that I guess

[torn shuttle]

seems like this specific test environment is on paper 100 for 1.17.1 for whatever reason

I can test on vanilla spigot in a second if that changes anything

[lost matrix]

But setting it invisible should work. Thats expected behavior.

[torn shuttle]

setting players won't work for me because that's dynamic and I really don't want to keep a task up just for this

man what am I typing today

[lost matrix]

Did you test the visibility in a discrete invironment?

[torn shuttle]

wdym

you think it might be plugin interference?

[fluid cypress]

this is executing the else part, even when passable blocks is clearly greater than 2, and safeBlocks definitely contains END_STONE at the index 20

[lost matrix]

Ill test it for you real quick

  private BossBar bossBar;

  @Override
  public void onEnable() {
    this.bossBar = Bukkit.createBossBar("§cTest", BarColor.BLUE, BarStyle.SEGMENTED_10);
    Bukkit.getScheduler().runTaskTimer(this, () -> this.bossBar.setVisible(!this.bossBar.isVisible()), 10, 10);
    Bukkit.getPluginManager().registerEvents(this, this);
  }

  @EventHandler
  public void onJoin(final PlayerJoinEvent event) {
    this.bossBar.addPlayer(event.getPlayer());
  }

[fluid cypress]

block.getType() should return END_STONE

so, what is happening? i cant see it

[torn shuttle]

you know I somehow suspect this is only happening for dragon specific boss bars and I can test that right quick

[lost matrix]

If the boss fight is going then im not sure if you can make the BossBar invisible.

[torn shuttle]

it's failing to hide even on the first tick

[lost matrix]

Works as expected

[torn shuttle]

can you try to do that specifically for the dragon

yeah confirmed

works for my custom boss bar

but not the dragon

well this is fun

[tawdry cedar]

Then you’re properly just gonna have to remove the player and add them back again :/

[lost matrix]

Then the active boss fight prevents the hiding of the bar

[torn shuttle]

so what, remove everyone on every tick?

[wispy monolith]

How do I check for an item by another plugin?

[tawdry cedar]

Have you tried printing out the value of passableblocks before the statement?

[wispy monolith]

I wanna make an if statement for an item not in my plugin

How?

[lost matrix]

Sysout the amount of passable blocks before the conditional statements

[wispy monolith]

Can I do it or not?

[tawdry cedar]

What’s the other plugin

[tawdry cedar]

Depends

[fluid cypress]

no, but could the debugger be wrong? its the second time i use it in intellij, idk how good or bad is it

[wispy monolith]

KitPvP

[tawdry cedar]

Uh can’t say I’ve used it before lol… I just System out print to the Minecraft console

[tawdry cedar]

Do you know if they have like an API or anything?

[lost matrix]

Usually its quite good. But you should def encase all blocks in brackets just to be sure. Its also enforced by almost any java code style.

[wispy monolith]

I don't think so. Ig they use spigot api only

[tawdry cedar]

Send a link to their spigot page

[lost matrix]

so

if() {

} else {

}

[tawdry cedar]

Also are you using maven @wispy monolith

[wispy monolith]

Yup

[tawdry cedar]

See if they have a maven repo and add the KitPvP plugin as a dependency

[fluid cypress]

its not printing it when it should, does it have a delay of a couple of frames or something like that?

i dont know whats happening, the thing i see in the console is totally different from the debugger

like, the debugger says passableBlocks is 12, but the console says its 8, and its still failing the condition

ill do the bracket thing

[torn shuttle]

I can't even make the boss bar invisible when the boss dies, sadface

[lost matrix]

Tha fk are you doing there?

[fluid cypress]

println should be instantaneous or not?

[lost matrix]

Yes. Its a blocking call to stdout

[torn shuttle]

even #removeAll() isn't working, this is really annoying

[lost matrix]

F

[fluid cypress]

wtf is wrong with this thing

[torn shuttle]

especially since if you #remove a dragon the boss bar just stays up

very cool

[lost matrix]

The only reason why the conditional statement could be false is if the collection you call contains() on doesnt have the Material in it. (If we can believe the debugger)
Did you check what type is actually produced by block.getType() ?

Oh yeah you did. Its END_STONE

[fluid cypress]

it was endstone on the first screenshot i send

now it could be anything

[lost matrix]

Just dig the player a hole to make some space XD

[fluid cypress]

maybe something is wrong with what im doing: im using paper for the sv and the paper api, im using maven to compile the jar, and the steps i followed to debug this thing were spigot as debugger, not the ide https://www.spigotmc.org/wiki/intellij-debug-your-plugin/

also i click the build project button, besides the package script from maven, just in case idk

[torn oyster]

On the bungeecord PluginMessageEvent, how do I get the serverinfo of the server that sent the plugin message?

[torn oyster]

is it e.getSender()

or whatever

cuz thats a connection

[lost matrix]

Yes.

[torn oyster]

how do i get serverinfo from that, then?

it returns a Connection

[lost matrix]

Check if Connection is instanceof Server. Then cast to Server.

[torn oyster]

oh lol

[fluid cypress]

Also, im using paperlib that does some things async when running on paper, but that code is running on the main thread, so, i dont think thats a problem

[lost matrix]

From there just use Server#getInfo()

[lost matrix]

I honestly didnt bother setting up a debug environment for my spigot/paper projects so i dont know what the implications of remote debugging are.

[lost matrix]

But if both, sysout and debugger, tell you that the space is bigger than 2 but the condition still fails then you got other problems. Mind sharing more of your code?

[rigid otter]

Hello! How can I get face of a sign? Face that contains text

[lost matrix]

Sign implements Rotatable

[lost matrix]

1. Get BlockData
2. Check if instanceof Sign
3. Cast to Sign
4. getRotation() from Sign

Be careful there are 2 Sign classes. You need org.bukkit.block.data.Sign

[rigid otter]

Ok thank you!

What about getting block which is wall sign attached to?

[lost matrix]

Same thing just with org.bukkit.block.data.WallSign
It implements Directional so you get the BlockFace using getFacing()

[rigid otter]

Ohh thanks!

[eternal oxide]

You could just check if BlockData is Attachable, then getAttached

oh I guess not

Sorry thats for trip wires and things

[quaint mantle]

@lost matrix

it didn't work out

public boolean isFullPlayerInventory(Player player) {

} else {

[lost matrix]

Nope. Not even close.
Start from here:

  public static boolean canFit(Inventory inventory, ItemStack itemStack) {
    int amountToAdd = itemStack.getAmount();
    int spaceForItem = 0;
    int maxStackSize = itemStack.getType().getMaxStackSize();

    for (ItemStack slotItem : inventory) {
      
    }

    return false;
  }

Then follow this:

Check if the slot item is null or air -> then add the maxStackSize to spaceForItem
else -> Check if slotItem is similar to itemStack -> then add the (maxStackSize - slotItem.getAmount()) to spaceForItem
Return true if spaceForItem is bigger than amountToAdd

[quaint mantle]

Okay, I'll try

[torn shuttle]

huh I just realized that the top google result for my issue is a post I made in 2018 covering what I just recreated now

completely forgot i did that

[vague oracle]

Why do you want to check if its full? Do you not want to add some items and leave the rest?

[lost matrix]

Because possibly incinerating have of a players rewards is a bad idea.

[tidal skiff]

how do i use e.disallow() with AsyncPlayerPreLoginEvent? im tryna make it so it kicks them but idk what it means by 'Result' and then string

the result part

ik what the string is

[vague oracle]

You are just setting the result reason, either whitelsit, ban, full and so on

[lost matrix]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/AsyncPlayerPreLoginEvent.html#disallow(org.bukkit.event.player.AsyncPlayerPreLoginEvent.Result,java.lang.String)

The String is the message.

[tidal skiff]

yep

alr so do i just put 'kick'

[vague oracle]

Put what ever you want it to be

[tidal skiff]

im still confused what it wants

does it want a string?

what is a Result

[vague oracle]

(AsyncPlayerPreLoginEvent.Result, String)

an enum

[lost matrix]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/AsyncPlayerPreLoginEvent.html#disallow(org.bukkit.event.player.AsyncPlayerPreLoginEvent.Result,java.lang.String)
Read the javadocs

[tidal skiff]

its so useless

i still have no idea what to do

[vague oracle]

Its not hard

event.disallow(AsyncPlayerPreLoginEvent.Result.KICK, "Kicked")

[tidal skiff]

oh

it just said blahblah.Result, String idk what it wanted me to do

ty

[vague oracle]

Its says AsyncPlayerPreLoginEvent.Result because its an inner enum inside the AsyncPlayerPreLoginEvent class.

[fluid cypress]

System.out.println("safeBlocks.contains(Material.NETHERRACK): " + safeBlocks.contains(Material.NETHERRACK));

[quaint mantle]

@lost matrix

public static boolean canFit(Inventory inventory, ItemStack itemStack) {

    return false;
  }
}

[fluid cypress]

its all Material

[quaint mantle]

2 and 3 did not understand

[lost matrix]

And collection class?

[fluid cypress]

List

[lost matrix]

Use an EnumSet

[torn oyster]

how do i make a getter using plugin messaging

like how do i do like

[fluid cypress]

the only thing i can think of is, im getting the list, and im using the contains method later, but if that was the problem, the thing printed in the console should be empty or different

[torn oyster]

getServerCount(server)

[lost matrix]

Super weird that this doesnt work. But try an EnumSet

[fluid cypress]

why?

[torn oyster]

and make it return an int

[fluid cypress]

is there something wrong with lists?

[lost matrix]

Much much faster than anything else. And its reliable.

[lost matrix]

Usually not. It only scales O(n) for contains.

[torn oyster]

how do i make a getter using plugin messaging
like how do i do like
getServerCount(server)
and make it return an int

[lost matrix]

Set yields a better performance and EnumSet even more so.

[fluid cypress]

ok, ill do that

but

this cant be happening

unless java is broken

Lists are from java, i mean, its not even my own collection class or something

[lost matrix]

Do you use openj9 or some other jvm fork?

[fluid cypress]

i use openjdk

[lost matrix]

Then there should be no problem.

[lost matrix]

Bukkit has a plugin message for that:
https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/#getservers

You need to listen for +send a message

[torn oyster]

no like

i have a send

and a receive

how do i do like

public int getMinigamePlayersLeft(server) {
    return blahblah;
}```

[lost matrix]

Dont. If you do that then you will produce massive lag.

[torn oyster]

then

how

how would i do this most efficiently

[lost matrix]

public void acceptMinigamePlayersLeft(Server server, IntConsumer consumer) {
  
}

delegate the function via a consumer

[torn oyster]

    public void findGame(ProxiedPlayer p, String minigame) {
        p.sendMessage(ChatColor.GREEN + "Server found!");
        
        List<ServerInfo> waitingServers = new ArrayList<>();
        for (ServerInfo info : foundServers.get(p)) {
            if (getMinigameState(info, not a real method yet).equalsIgnoreCase("PRE_GAME")) {
                waitingServers.add(info);
            }
        }
    
        matchmaking.remove(p);
        foundServers.remove(p);
    }```

how

idk

[lost matrix]

Pls describe your setup. Are you writing a plugin for BungeeCord or Spigot or both? What exactly are you trying to do.

[fluid cypress]

how do i create an enumset?? i get 'EnumSet' is abstract; cannot be instantiated

EnumSet<Material> test = new EnumSet<>();

i dont remember too much about abstract classes

[torn oyster]

thats on a bungee plugin

both

[lost matrix]

EnumSet.noneOf(Material.class) for example

[torn oyster]

im trying to make a matchmaking thing

minigames

[lost matrix]

Thats a bit complicated.
You need to take a really object oriented approach for this or it will be a mess.

[lost matrix]

The proxy should hold game instances which the servers can register. Then the servers can send users to those game instances. When the queue us full, the proxy sends all players to the right server instance and starts the game.

[tight sluice]

hey guys ehh I'm fairly new to making plugins and I'm having trouble with dealing with packets
I'm trying to set the items in a inventory created with packets with the help of protocollib
but I can't seem to find a way to set a specific slot in that inventory to an item

[lost matrix]

The actual implementation strongly depends on your game setup and can get quite complicated fast. Be sure you know how to properly handle async requests and know
how to forward methods using Consumer<>

[native nexus]

Why would you need to set items in an inventory with packets...?

[lost matrix]

How much java experience do you have?

[tight sluice]

I don't actually know but I figured that it would be harder for players to like uhh dupe I guess with a fake window

[lost matrix]

[tight sluice]

I know the basics but not really much

[lost matrix]

The only reason why you would want packet based ItemStacks is so multiple people see the same ItemStack differently.

[lost matrix]

Dont tinker with packets. If you properly use the API then dupe save GUIs are possible.

[native nexus]

The biggest purpose of ProtocolLib is for a player to see what other players don't see

[tight sluice]

I still kinda want to know how what I wanna done should be done even if I don't really need it now...

I kinda figured out that I'd just need to do this

        PacketContainer pc = main.pm.createPacket(PacketType.Play.Server.WINDOW_ITEMS);
        pc.getIntegers().write(0,1);
        List<ItemStack> l = new ArrayList<ItemStack>(0);
        l.add(new ItemStack(Material.GLASS_PANE, 1));
        pc.getItemListModifier().write(0, l);

for adding items

[lost matrix]

Packets are not part of the API. So if you want to do that then you need to look at the protocol specification:
https://wiki.vg/Protocol#Window_Items

[torn oyster]

i just wanna know how to do a get system with plugin messaging, i have all the other stuff down

it works

[tight sluice]

but that only add items like uhh in order I guess?

[native nexus]

@lost matrix Have you worked with MongoDB much? If so would you recommend the POJO approach or just plain old documents?

[tight sluice]

I did look at it but can't really figure out how I should do it if say, I wanna set the 3rd slot of an inventory to something else without messing with the first 2 slots

[quaint mantle]

@lost matrix

[tight sluice]

having the first 2 itemstack in the list set to null just kicks the client

[reef wind]

Pojo is great.

[lost matrix]

The list you send has to line up with the inventory slots. If you want to make spaces then you need to add null entries in the list

[tight sluice]

and setting it to air removes the first 2 items

[quaint mantle]

@reef wind

[reef wind]

stop

[torn oyster]

hey prouddesk

[reef wind]

I won’t help you again, last time was a pain and you didn’t even listen. @quaint mantle

[torn oyster]

me?

oh

lol

[tight sluice]

https://imgur.com/a/av4rlQb
this happens tho if I set it to null

[lost matrix]

I really like document based databases for minecraft servers. The simple Data -> Gson/Jackson -> MongoDB approach works great for arbitrary data.

[reef wind]

It’s a nullpointer

[native nexus]

Yeah for sure, I have a soft spot for NoSQL databases

[lost matrix]

Uhm. Try adding air ItemStacks then.

[tight sluice]

that simply removes the first 2 items

[torn oyster]

do you know how to make a method that gets a plugin message value
like if i made a custom plugin message thingy that gets a value from a server and returns it instantly
for example
i have a value which is 7 on my spigot pluign
i want to be able to do like getValue(Server) on my bungee plugin and instantly get the int using plugin messaging
is this possible? if so, how can i do it

[tight sluice]

do I have to resent the whole inventory if I just wanna change say the 3rd item?

[quaint mantle]

@reef wind

[lost matrix]

This will block and fk up your server

[torn oyster]

is there a way around it

how do i make a way around it

[lost matrix]

No. There is a different packet for that.

[tight sluice]

cause the packet works with like only 1 item on the list

[quaint mantle]

it didn't work

[lost matrix]

delegation

[reef wind]

[ivory sleet]

?kick @quaint mantle English thanks

[undone axle]

Done. That felt good.

[fluid cypress]

but i want a set

[lost matrix]

Then use a Set...

[fluid cypress]

omg i literally hate java, its so unconsistent

the clone method doesnt exist on a Set

i mean, its private

also, the Set class is abstract

[lost matrix]

https://docs.oracle.com/javase/7/docs/api/java/util/HashSet.html#HashSet(java.util.Collection)
new HashSet<>(map.keySet())

[fluid cypress]

HashSet?? what is that

ok thanks

[lusty cipher]

the most common implementation of a Set (as Set is just an interface)

[lost matrix]

A hash based set.

Basically the key arm of a HashMap

[fluid cypress]

thats another question, why its always List x = new ArrayList instead or ArrayList x = new... or List x = new List, or Map<> x = new HashMap instead of Map = new Map

i mean, why is the type

different than the constructor

[eternal night]

In OOP you usually want to be as abstract as possible when defining variables

A var of type list can hold an array list, a linked list, or any other implementation straight from hell

[lost matrix]

List is the interface and ArrayList is the implementation. There are several implementations for List with very different properties.

List<String> someList = new ArrayList<>();
List<String> someOtherList = new LinkedList<>();

Both viable but with different properties

[lusty cipher]

because realistically, you don't really care for what implementation of the type it is. List is enough, as you most likely just want to access methods like add, size etc.

[fluid cypress]

mmm

right, the List interface is just telling "this object will have this shape, this structure"

thats why its green, its an interface

but, then i could be able to do ArrayList x = new ArrayList<type>()

[ivory sleet]

Liskov substitution principle (:

[fluid cypress]

idk, its confusing, im tired af, i need to sleep

[lost matrix]

If it was bordeaux it would still be an interface...

[ivory sleet]

🥴

[lost matrix]

But right

[torn shuttle]

so wait even using nms the only real way of stopping boss bars from active dragons from being sent is to prevent the packets from being sent?

maybe if I ignore this issue it will go away

[lost matrix]

Just listen with plib and bash the packets away

chose one player at random and just delegate all that trash to him. See how his client handles all that.

[torn shuttle]

this is so cursed

[lost matrix]

Actually that sounds like a fun plugin. Randomly shuffling packets to random players.

[torn shuttle]

mine4packets

every block you mine you get a random packet

[fluid cypress]

btw i found the safeBlocks.contains problem. yes, it was a list of strings, not material, being casted to material when reading from the config in a lot of nested for loops

so dont worry guys, java isnt broken

but my question is

how can i cast a string to material??

without a runtime exception or something

[torn shuttle]

^

[lost matrix]

String -> Enum
Enum.valueOf(String)

[torn shuttle]

how can I cast bad code to good code

[native ruin]

I'm having a problem getting my plugin to work on the server.
Logs say the error is in plugin.yml
More specifically at the " main"
I've read the documentation but I can't seem to make it work
Right now it is

main: xceing.plugin.main
main:[packagename].[main class name] 

[fluid cypress]

i mean, im not asking how to do it, im asking how can a just cast string type to material type without an error

or youre saying that java does that automatically?

[torn shuttle]

try catch is your friend

[reef wind]

the error would be helpful and also is the main class located there?

[native nexus]

Material.matchMaterial(string) ?

[fluid cypress]

im asking WHY isnt it throwing an error when i do (Material)String, im not asking how to do it correctly, i already fixed it

[lost matrix]

You cant randomly cast stuff around. You need to get the Enum from the String by using Enum.valueOf(String)
In Material its safer to use Material.matchMaterial(String)

[native ruin]

It is located in that package and extends Java plugin

[reef wind]

what is the error?

[native ruin]

Cannot find main class

[reef wind]

the it’s not located there

[lost matrix]

That is just weird. Maybe you have a try catch block that just doesnt print the stack trace

[fluid cypress]

ive been using Material.getMaterial, whats the difference?

[native nexus]

Read javadocs

[ivory sleet]

Doesn’t throw

[lost matrix]

matchMaterial is safer in regards to parsing String which might not be in the Material enum

[native nexus]

Javadocs is your best friend
