I just realized tonight that you can do switch expression variable initializations in Java 😂

#

Was on Java 8 for too long and then went to Kotlin

dusty frost Aug 24, 2022, 3:40 AM

#

Switch expressions 😌

errant kraken Aug 24, 2022, 8:26 AM

#

So I am extending an abstract class and I have this method ```
@Override
public void join(Player player) {
joinPlayer(player);
}

Is there a way to somehow call joinPlayer (which is also a method in the abstract class) every time join is called instead of having to manually call it in the child class like this?

#

I am basically trying to create some default functionality alongside whatever the dev wants to add later

sterile hinge Aug 24, 2022, 8:39 AM

#

well whenever a method is overridden, you lose the default behavior as long as super.<method>() isn't called

#

is it possible that generating only for example 8 chunks with vanilla word generation and anything else is just air

#

like can i achive this with a plugin or need to make changes in server jar

#

its like skyblock generation actually

#

i guess thats works too

loud sorrel Aug 24, 2022, 11:39 AM

#

so you wouldn’t be able to prevent block generation on the first run because the world is generated before the plugin is initialized. but, i did see someone delete chunk files

#

you could also just use worldedit if u need to do it once

nimble vale Aug 24, 2022, 11:39 AM

#

i can make it once but it needs to be like unlimited* amount of that chunks

#

i also need to change the world generator to make it only a specific biome etc etc

#

i don't really know where to start

hoary scarab Aug 24, 2022, 11:57 AM

Create void world, select chunk, create chunk generation, load chunk.

Also if you're trying to do this like skyblock you're gonna need a method to get a new location somewhere in the world.
Easiest would be checking if x >lastX z<lastZ and so on. I think bentobox uses this check if you want to look at their code it's open source.

nimble vale Aug 24, 2022, 12:03 PM

#

is it possible to load only a chunk with a worldgenerator

#

like there will be a space between them

hoary scarab Aug 24, 2022, 1:18 PM

#

I'm sure you can set a chunks generator and run chunk regen. (I could be wrong though. Testing required.)

is there an event for checking when the placeholder value is change in PlaceholderApi

lyric gyro Aug 24, 2022, 1:26 PM

#

no

#

PAPI is entirely based around polling the value of a placeholder, it's more of an "evaluate this expression" kind of thing

#

@kind granite thoughts?

tropic pasture Aug 24, 2022, 1:32 PM

okay thanks

hope it exist Xd

What do you want to track though?

#

You’re probably better off checking it from the original plugin or just regular events instead of checking when placeholders change

tropic pasture Aug 24, 2022, 2:35 PM

#

yes but if there is an event for it, i can do just check the placeholder change event instead of checking every plugin and get the api from that plugin

is it possible to check if a mob can get to another mob
for example if the zombe is in a 2 block hole the answer is false
if it has a block over it's head and in a 1 block cage
false
but it there is nothing restricting it and if the player were to go afk the zombie could attack the player
the answer is true

Quick question, there is the PlayerPortalEvent whoch detects when the players enters the portal, but does that include the animation or not (if in survival)? If it does include the animation, is there an event for when the player "touches" the portal?

worn jasper Aug 25, 2022, 8:48 AM

That means PlayerPortalEvent doesnt include the animation?

proud pebble Aug 25, 2022, 9:13 AM

Like %stats_[arena]%

can replace anything on [arena]

dusky harness Aug 25, 2022, 11:33 AM

#

hybrid dome is there any way to make the placeholders dynamic?

yes - the only thing PAPI checks for is that stats is what you specified

hybrid dome Aug 25, 2022, 11:36 AM

#

dusky harness yes - the only thing PAPI checks for is that `stats` is what you specified

can you give me an example?

dusky harness Aug 25, 2022, 11:36 AM

#

hybrid dome can you give me an example?

uhhh
can you show me your current code first?

#

and I'll show you from there

hybrid dome Aug 25, 2022, 11:36 AM

#

dusky harness uhhh can you show me your current code first?

i didn't writte anything

please don't angry me

dusky harness Aug 25, 2022, 11:37 AM

#

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/PlaceholderExpansion#with-a-plugin-internal-class

#

^ example

dense drift Aug 25, 2022, 11:37 AM

#

you have a String parameter on the onRequest method

#

that's everything you have after stats_

dusky harness Aug 25, 2022, 11:37 AM

#

this

hybrid dome Aug 25, 2022, 11:37 AM

#

i mean

#

a dynamic placeholder

dusky harness Aug 25, 2022, 11:38 AM

#

that is dynamic

hybrid dome Aug 25, 2022, 11:38 AM

#

that's too much case

#

i am bad at explaing

#

sorry

#

i want to check stats from players from a random arena

#

i can't create all placeholders for them

#

then i want to create %stats_[arena]%

dusky harness Aug 25, 2022, 11:39 AM

#

I don't know what method you use to get status from players from an arena

hybrid dome Aug 25, 2022, 11:39 AM

#

to show a stats from that arena

dusky harness Aug 25, 2022, 11:40 AM

#

so unless I know I can't say much besides that params will give you [arena]

#

all PAPI controls is that first part

#

stats

#

if the placeholder matches %stats_PARAMS%, it gives it to your method (onRequest)

hybrid dome Aug 25, 2022, 11:41 AM

#

ok, i want to create placeholders like ajleaderboard (that is what i want from the start, sorry for bad explaining)

dusky harness Aug 25, 2022, 11:41 AM

#

dusky harness so unless I know I can't say much besides that `params` will give you `[arena]`

I don't know how your plugin is setup

#

it depends on each plugin

hybrid dome Aug 25, 2022, 11:42 AM

#

i have a variable

#

to get the arena stats

#

but it is required

#

the arena name from the placeholder

dusky harness Aug 25, 2022, 11:43 AM

#

what is the variable type

hybrid dome Aug 25, 2022, 11:43 AM

#

dusky harness what is the variable type

int

dusky harness Aug 25, 2022, 11:43 AM

#

okay but what variable do you store arena stats in

hybrid dome Aug 25, 2022, 12:24 PM

#

a value of a config path

hybrid dome Aug 25, 2022, 12:24 PM

#

dusky harness okay but what variable do you store arena stats in

dense drift Aug 25, 2022, 2:28 PM

Also make sure you've registered your event. Hmu if it works/doesn't work.

granite hound Aug 25, 2022, 10:52 PM

#

ok

granite hound Aug 25, 2022, 10:56 PM

warm steppe Also make sure you've registered your event. Hmu if it works/doesn't work.

do i have to register it in my main or in this class?

warm steppe Aug 25, 2022, 10:56 PM

#

Main

granite hound Aug 25, 2022, 10:57 PM

#

also i mod c# unity games and i know you have to call from main is that here too?

warm steppe Aug 25, 2022, 10:57 PM

#

You get your PluginManager instance and register your event with #registerEvents(Listener, JavaPlugin);

#

d;PluginManager#registerEvents

uneven lanternBOT Aug 25, 2022, 10:58 PM

org.bukkit.plugin.PluginManager#registerEvents

void registerEvents(@NotNull Listener listener, @NotNull Plugin plugin)```

Description:

Registers all the events in the given listener class

Parameters:

listener - Listener to register
plugin - Plugin to register

how expensive is the call to this method?

}

granite hound Aug 25, 2022, 11:00 PM

#

warm steppe You get your PluginManager instance and register your event with `#registerEvent...

do you mean like this? @Override
public void onEnable() {
// Plugin startup logic
void registerEvents(@NotNull
Listener this,
@NotNull
JavaPlugin ActivateTrap)

warm steppe Aug 25, 2022, 11:00 PM

#

hmm, not quite

#

you need to pass your event (listener) instance (new ActivateTrap())

#

and for the second parameter you can use this keyword

granite hound Aug 25, 2022, 11:02 PM

#

ok so like this @Override public void onEnable() { // Plugin startup logic void registerEvents(@NotNull Listener (new ActivateTrap()), @NotNull JavaPlugin this)

winged pebble Aug 25, 2022, 11:02 PM

#

Still not quite

#

Bukkit.getPluginManager().registerEvents(new ActivateTrap(), this);```

#

khem..., ;, khem...

yo , so ive been trying to create something using an external API that has almost no documentation (savage factions) and I have been trying to find a way to find out if the target block is in a Wilderness / warzone chunk

#

can anyone help the api literally doesnt say anything

Getting the faction

#

its right there

#

wilderness and warzone are both factions

unborn ivy Aug 26, 2022, 9:58 AM

proud pebble Getting the faction

so how can i make it only identify wilderness/warzone

nvm

proud pebble Aug 26, 2022, 9:59 AM

unborn ivy so how can i make it only identify wilderness/warzone

i would assume Faction would contain something to identify it by

hey guys i want to make a deathrun game and the trap activator works but i want to make a basic trap that the red blocks dissapear and the green stay so red and green concrete but i want it to only be in the single area is that possible to select a radius or do i have to specify every blocks coordinate? also would it be possible to make it so you can set the traps up in game as the game will have multiple maps

edgy lintel does persistentdatacontainer essentially a multiversion nms data storage api?

pretty sure PDC stores the tags as nbt tags under the bukkit namespace. so if your question was meant to say is instead of does, I guess the answer is yes

yes i was having a brain malfunction after heavy bombarding of nms management

dense drift Aug 26, 2022, 11:26 AM

is bukkit's NBT implementation

edgy lintel Aug 26, 2022, 11:27 AM

#

broken elbow pretty sure PDC stores the tags as nbt tags under the bukkit namespace. so if yo...

so the storage is in bukkit data yml or inside the nbt

#

ohh alr so its still stored in minecraft nbttag

dense drift Aug 26, 2022, 11:27 AM

#

nbt, but you can't edit any tag you want

edgy lintel Aug 26, 2022, 11:27 AM

#

oh alr got it

broken elbow Aug 26, 2022, 11:27 AM

#

it is stored wherever NBT tags are stored

#

since they're nbt tags

#

in the end, just with the bukkit namespace

hey guys i have a question i made it so that when right clicking green glass with slime ball it kills you but i want to activate traps but to do that first i need to be able to make it so that they have different triggers so when i click one green glass with a slimeball something will happen but when doing the same but on a different glass its still green glass but just in another place i need something else to happen does anyone know a way to do that?

you make a an object

#

that contains all the information you need with the event

#

for example

granite hound Aug 26, 2022, 12:10 PM

#

merry knoll that contains all the information you need with the event

Sorry I meant if I needed to make an event for the different traps

merry knoll Aug 26, 2022, 12:11 PM

#

depends, i would make an event for all trap triggers

#

so you can listen to it

#

and go like (redblocktrigger -> fire trap)

#

you can also use the bukkit event system

granite hound Aug 26, 2022, 12:12 PM

#

Ok and the problem is that it should all be green glass but should do different stuff

merry knoll Aug 26, 2022, 12:12 PM

#

okay so then you do this instead

granite hound Aug 26, 2022, 12:12 PM

#

So green glass but there are multiple green glasses but they do different stuff

merry knoll Aug 26, 2022, 12:12 PM

#

then create a type enum

#

and make your event object have a field with the type

#

so you can check what kind of green grass triggered your event

#

then on your listener

#

you can go

#

switch(type)
case ArrowTrap
case FallTrap

#

etc

#

or another approach is to create an event for each trap type

#

so you just listen to ArrowTrapTriggeredEvent

#

// do logic on arrow trap trigger

#

probably cleaner

#

but i would make an event interface that shares the triggering block and such

granite hound Aug 26, 2022, 12:14 PM

#

merry knoll etc

Ok because the trap types are specified to the area but the traps have different areas in the map too as there are multiple of the same traps but just with other activor green stained glass blocks

merry knoll Aug 26, 2022, 12:15 PM

#

you pass all those in the event object

#

give me a second, i will give you an example

granite hound Aug 26, 2022, 12:16 PM

#

Thanks

merry knoll Aug 26, 2022, 12:21 PM

#

public abstract class TrapTriggeredEvent {
    private final Block  triggeringBlock;
    private final Player triggeringPlayer;

    public TrapTriggeredEvent(Block triggeringBlock, Player triggeringPlayer) {
        this.triggeringBlock = triggeringBlock;
        this.triggeringPlayer = triggeringPlayer;
    }

    public Block getTriggeringBlock() {
        return triggeringBlock;
    }

    public Player getTriggeringPlayer() {
        return triggeringPlayer;
    }
}

#

your generic trap event

#

public class ArrowTrapEvent extends TrapTriggeredEvent{
    public ArrowTrapEvent(Block triggeringBlock, Player triggeringPlayer) {
        super(triggeringBlock, triggeringPlayer);
    }
}

#

a specific trap event

#

and while listening, you do it bukkit style

#

public class ArrowTrapListener implements TrapListener {

    @Override
    public void onTrapTrigger(ArrowTrapEvent event) {
        // do stuff
    }
}

#

this is how i would probably do it

#

@granite hound

granite hound Aug 26, 2022, 12:25 PM

#

thanks

merry knoll Aug 26, 2022, 12:25 PM

#

obv you change the paramaters and fields

#

to match what you need

granite hound Aug 26, 2022, 12:26 PM

#

yeah i should change my the code in super() right?

merry knoll Aug 26, 2022, 12:27 PM

#

super calls TrapTriggeredEvent constructor there

#

since the specific event is extending it

#

you put the shared stuff into the trap triggered event

#

and specific stuff into the specific events

#

if you only have a type that changes

granite hound Aug 26, 2022, 12:28 PM

#

ok

merry knoll Aug 26, 2022, 12:28 PM

#

between traps and no other info changes, then you dont need the different event approach imho

#

i would just make an enum in that case

granite hound Aug 26, 2022, 12:28 PM

#

so in trap triggered the triggerblock should be set to glass

merry knoll Aug 26, 2022, 12:29 PM

#

no, you are not setting any of those by hand

#

your producer is creating these objects

#

dynamically as they happen

granite hound Aug 26, 2022, 12:29 PM

#

ok

merry knoll Aug 26, 2022, 12:29 PM

#

producer example is in the link i posted

#

above

granite hound Aug 26, 2022, 12:31 PM

#

shouldnt this line be this.triggeringBlock = GREEN_STAINED_GLASS;?

#

right

merry knoll Aug 26, 2022, 12:32 PM

#

no

granite hound Aug 26, 2022, 12:32 PM

#

ok

merry knoll Aug 26, 2022, 12:32 PM

#

GREEN_STAINED_GLASS doesnt even exist

#

its a Material.GREEN_STAINED_GLASS

#

and a material is not a block

granite hound Aug 26, 2022, 12:33 PM

#

ok because my activator works but currently when you click it with a slimeball you just die

merry knoll Aug 26, 2022, 12:34 PM

#

you can do what you want to do simpler with just if else / switch cases

granite hound Aug 26, 2022, 12:43 PM

#

merry knoll you can do what you want to do simpler with just if else / switch cases

broken elbow Aug 26, 2022, 1:55 PM

conflictsWith doesn't return a list it returns a boolean

you're supposed to check what the other enchantment is and return true/false depending if they conflict or not

#

also conflictsWith can accept a list of enchantments yes

#

there's 2 methods

I mean it requires a enchantment and ig it accepts a List of Enchantments as well

you either wrap the whole thing in another while

or you call the function again

from the function

so it recursively repeats

how do i call the function again?

how will my brain ever grasp what is happening

torpid raft or just add an ``` if contador == 5) contador = 0 ```

thank you

i also added a blank sout at the end

just to make things a little bit less confusing

#

but

#

now it's counting only up to 4

#

what do i do

ill just increase the while by one

now it's working

its spigot

#

and what do you mean built in ways

winged pebble Aug 26, 2022, 8:18 PM

#

The exact same way that bukkit does events

#

You just have your custom event that is fired when it happens, and your Listener that works the exact same way as the other events

granite hound Aug 26, 2022, 8:21 PM

#

You have them as private

winged pebble Aug 26, 2022, 8:32 PM

#

granite hound also for some reason the triggering block and player have private access but eve...

What do you mean by this

#

As that's not the right Block

#

And your class needs to extend bukkit's Event

granite hound Aug 26, 2022, 8:35 PM

#

ok so i changed that but where are they set private?

granite hound Aug 26, 2022, 8:36 PM

#

winged pebble You have them as private

also where should i do Bukkit.getPluginManager().callEvent(<your event here>)? in my main or in my activatetrap?

winged pebble Aug 26, 2022, 8:37 PM

#

When you want the event to be fired

granite hound Aug 26, 2022, 8:37 PM

#

when they right click with a slimeball on green glass oooo

#

yeah

#

its the activate

#

but do i still need new ArrowTrapEvent(); then?

winged pebble Aug 26, 2022, 8:39 PM

#

Well as it stands, I see no reason to have that class, it doesn't add anything different than the TrapTriggerEvent

granite hound Aug 26, 2022, 8:41 PM

Does anyone know if it is doable to store T as a variable in Java?
I currently have this method:

public <T> T getFavicon(Function<BufferedImage, T> function) {
    return function.apply(image); // image is a BufferedImage instance
}

And I want to change it so that it would return T directly if it already has made it before.
Like something similar to f.e.

public <T> T getFavicon(Function<BufferedImage, T> function) {
    if (cached != null)
        return cached;

    return (cached = function.apply(image));
}

What did you change it to

Bukkit.getPluginManager().callEvent(ArrowTrapEvent);

winged pebble Aug 26, 2022, 8:47 PM

You have to pass in a variable

lyric gyro Aug 26, 2022, 8:47 PM

#

just watched a java tutorial and I didn't really understand. Can someone help me understand this code? please ```class theThread implements Runnable{

String name;
Thread t;

theThread(String name){
    this.name = name;
    t = new Thread(this, name);
    System.out.println("Created New Thread: " + t);
}

public void run() {
    try{
        for (int i = 5; i > 0; i--){
            System.out.println("Thread: " + t + " " + i);
            Thread.sleep(1000);
        }
    }catch (InterruptedException e){
        System.out.println(e);
    }

    theThread2.t.start();
    theThread3.t.start();



}

}```

granite hound Aug 26, 2022, 8:49 PM

#

also @winged pebble if i do it from activatetrap would i still be able to make it so on some green stained glasses when clicked with slimeball it activates a arrowtrap but then on another its for example a parkourtrap?

winged pebble Aug 26, 2022, 8:50 PM

#

I have no idea

#

Probably though

somber gale Aug 26, 2022, 8:51 PM

#

winged pebble Where does T come from?

In my case is it just in the function itself and is defined by whatever the function would return.

granite hound Aug 26, 2022, 8:51 PM

#

because now it activates it when pressed with a slimeball but i want the same to be done but have a different result depending on what the glass should be assigned too

somber gale Aug 26, 2022, 8:51 PM

#

I chose this as it allows me a single method to convert a BufferedImage to any Favicon object using their factory methods

granite hound Aug 26, 2022, 8:52 PM

#

winged pebble Probably though

i dont think so do maybe that was why the 2 other scripts where needed?

winged pebble Aug 26, 2022, 8:52 PM

Well if you want to implement a cache system, then you'd need to pull the generic out to the class level instead

#

As the type is no longer determined by the input to the function

granite hound Aug 26, 2022, 8:55 PM

#

winged pebble Well I don't really understand your scenario tbh

do you know the minigame deathrun previously seen in the hive and now only on bedrock?

winged pebble Aug 26, 2022, 8:55 PM

#

I highly suggest you look into some Java tutorials btw

granite hound Aug 26, 2022, 8:55 PM

#

ok

winged pebble Aug 26, 2022, 8:55 PM

#

There are a lot of things you're messing up on by not knowing java/oop basics

#

Let me see if I understand what you are trying to do

#

You want to listen for when the player uses a slimeball on a block, depending on the type of block, it will create a certain type of trap?

granite hound Aug 26, 2022, 8:57 PM

#

winged pebble You want to listen for when the player uses a slimeball on a block, depending on...

nope

#

its the same block and the same item but a different type of trap

winged pebble Aug 26, 2022, 8:57 PM

#

How are you going to differentiate what kind of trap they are trying to make?

granite hound Aug 26, 2022, 8:57 PM

#

the glass is in front of the area where the trap should be

#

i was thinking of connecting them

merry knoll Aug 26, 2022, 8:58 PM

#

winged pebble How are you going to differentiate what kind of trap they are trying to make?

i was the one that gave him that code as example

winged pebble Aug 26, 2022, 8:58 PM

#

Okay, so basically what I said, but slightly different

granite hound Aug 26, 2022, 8:58 PM

#

yeah

merry knoll Aug 26, 2022, 8:58 PM

#

idea was that he would extend the generic event with the different trap types

granite hound Aug 26, 2022, 8:58 PM

#

because i also need to set the areas that the trap cover

granite hound Aug 26, 2022, 8:59 PM

#

merry knoll idea was that he would extend the generic event with the different trap types

also btw thanks a lot for helping

winged pebble Aug 26, 2022, 8:59 PM

#

Well you're going to have to use the interact event to determine which kind of trap they are making

#

I don't see a lot of benefit in making an event for the creation of the trap though, as interact pretty much does what you need

merry knoll Aug 26, 2022, 9:00 PM

#

i would personally just make different trap events and fire them as needed

winged pebble Aug 26, 2022, 9:01 PM

#

I don't see the benefit of that

merry knoll Aug 26, 2022, 9:01 PM

#

as they get triggered

#

its cleaner since logic goes into different classes then

winged pebble Aug 26, 2022, 9:01 PM

#

The interact event is going to do all the heavy lifting

merry knoll Aug 26, 2022, 9:01 PM

#

yeah obviously

#

but you avoid a big class

winged pebble Aug 26, 2022, 9:01 PM

#

Making separate events for each type of trap is overkill

#

Not really

lyric gyro Aug 26, 2022, 9:01 PM

#

lyric gyro just watched a java tutorial and I didn't really understand. Can someone help me...

this

winged pebble Aug 26, 2022, 9:01 PM

#

The interact just says oh, you want this type of trap boom it's made

merry knoll Aug 26, 2022, 9:02 PM

#

lyric gyro just watched a java tutorial and I didn't really understand. Can someone help me...

stay away from threads

#

until you have a bit more experience

winged pebble Aug 26, 2022, 9:02 PM

#

Whereas creating a separate event to fire just creates another step

merry knoll Aug 26, 2022, 9:02 PM

#

getting into concurrency will just make it mroe confusing

lyric gyro Aug 26, 2022, 9:02 PM

#

merry knoll until you have a bit more experience

threads arent that hard

#

I managed to do somethings with it

merry knoll Aug 26, 2022, 9:02 PM

#

concurrency and thread safety is

#

i highly doubt you managed to cover for race conditions

lyric gyro Aug 26, 2022, 9:02 PM

#

but I don't understand how that code works

lyric gyro Aug 26, 2022, 9:03 PM

#

merry knoll i highly doubt you managed to cover for race conditions

whats that

#

im just watching the playlist in order

#

not skipping anything

merry knoll Aug 26, 2022, 9:03 PM

#

when you have multiple workers

#

editing a variable becomes an issue

#

since its state is not guaranteed

#

translation is

granite hound Aug 26, 2022, 9:03 PM

#

yeah but the problem is that there will be multiple maps and there will be multiple of the same trap in the same map so it would be nice to make it be simple to set up what the area of the trap is with worldedit or some other plugin or something so you can link your trap area you selected with a green glass or something?

merry knoll Aug 26, 2022, 9:04 PM

#

lets say you got an int a = 0

#

and you have two threads increasing its amount by 1

#

1000 times each

#

at the same time

#

you would normally expect the end result as 2000

#

but you will get a number between 1000 - 2000 each time

threads is a bit after that

winged pebble Aug 26, 2022, 9:05 PM

this

lyric gyro Aug 26, 2022, 9:06 PM

#

can someone explain the code though

#

what is it doing

#

how

#

why

#

whats the purpose

merry knoll Aug 26, 2022, 9:06 PM

#

your first class is expanding runnable

#

meaning that it is a class with a function in it

lyric gyro Aug 26, 2022, 9:07 PM

#

runnable being an interface

#

correct?

winged pebble Aug 26, 2022, 9:07 PM

#

Yes

merry knoll Aug 26, 2022, 9:07 PM

#

that function is the run() method

#

yes

lyric gyro Aug 26, 2022, 9:07 PM

#

a function is?

winged pebble Aug 26, 2022, 9:07 PM

#

public void run() {
}

lyric gyro Aug 26, 2022, 9:07 PM

#

thats basically a function?

merry knoll Aug 26, 2022, 9:07 PM

#

yes

winged pebble Aug 26, 2022, 9:07 PM

#

that is a function

lyric gyro Aug 26, 2022, 9:07 PM

#

just a method

merry knoll Aug 26, 2022, 9:08 PM

#

what an interface does

winged pebble Aug 26, 2022, 9:08 PM

#

a method is a function that belongs to a class

merry knoll Aug 26, 2022, 9:08 PM

#

is define a default template

lyric gyro Aug 26, 2022, 9:08 PM

#

i know what an interface does

#

dw i understand interfaces

merry knoll Aug 26, 2022, 9:08 PM

#

okay, then thats basically it

lyric gyro Aug 26, 2022, 9:08 PM

#

my biggest question is with t

#

what is t

#

and what is it doing

icy shadow Aug 26, 2022, 9:08 PM

#

t is the Thread

winged pebble Aug 26, 2022, 9:08 PM

#

it is the field inside of the class

icy shadow Aug 26, 2022, 9:08 PM

#

yeah

merry knoll Aug 26, 2022, 9:08 PM

#

its a thread

lyric gyro Aug 26, 2022, 9:09 PM

merry knoll Aug 26, 2022, 9:09 PM

it breaks convention

That depends on experience tbh, it is doable though

#

jk

merry knoll Aug 26, 2022, 9:10 PM

#

with stacktrace

#

so up to you honestly

#

KEKW

lyric gyro Aug 26, 2022, 9:11 PM

#

ok so

#

now I know that t is just a thread

#

but

winged pebble Aug 26, 2022, 9:11 PM

#

It just makes it easier to read code faster

merry knoll Aug 26, 2022, 9:11 PM

#

imagine a thread

#

as a worker

lyric gyro Aug 26, 2022, 9:11 PM

how does it have access to other threads

#

It doesn't

lyric gyro Aug 26, 2022, 9:11 PM

#

how does it know

granite hound Aug 26, 2022, 9:11 PM

#

winged pebble That depends on experience tbh, it is doable though

ok because im going to work on my java better but i plan to do this after i got this pulled off as its not that much anymore besides that and i want it off my mind

lyric gyro Aug 26, 2022, 9:11 PM

#

what other threads are doing

merry knoll Aug 26, 2022, 9:11 PM

it doesnt

winged pebble Aug 26, 2022, 9:13 PM

#

Normally, code executes from top to bottom, when you introduce concurrency, you start to have branches

icy shadow Aug 26, 2022, 9:13 PM

#

in modern java you dont tend to use the Thread class directly anyway, there are much more modern patterns for handling concurrency

merry knoll Aug 26, 2022, 9:13 PM

threads are extremely useful, but you need to know what you are doing

granite hound Aug 26, 2022, 9:13 PM

icy shadow Aug 26, 2022, 9:18 PM

it's a meme

granite hound Aug 26, 2022, 9:18 PM

#

o ok

merry knoll Aug 26, 2022, 9:18 PM

#

its way better than java

icy shadow Aug 26, 2022, 9:18 PM

#

ehhhhh

#

we'll have to agree to disagree on that one

merry knoll Aug 26, 2022, 9:19 PM

#

the amount of publics and statics i avoid typing

lyric gyro Aug 26, 2022, 9:19 PM

#

fun

#

is the name of one of the commands

icy shadow Aug 26, 2022, 9:19 PM

#

merry knoll the amount of publics and statics i avoid typing

companion object 🤓

lyric gyro Aug 26, 2022, 9:19 PM

#

imagine writing "fun"

#

while enraged that your program didn't work

merry knoll Aug 26, 2022, 9:19 PM

#

just object usually if you want static access

cinder forum Aug 26, 2022, 9:19 PM

#

lyric gyro yeah fuck kotlin too

just RIIR!

granite hound Aug 26, 2022, 9:20 PM

#

granite hound hey should i use worledit or some other plugin like a flags plugin or something?

hey what you guys think i should use? i think either worldguard or standalone fawe/worledit

icy shadow Aug 26, 2022, 9:20 PM

#

worldedit is the de-facto standard

lyric gyro Aug 26, 2022, 9:20 PM

#

so I came here asking what de code doin

#

and all i understood was

#

"t is a thread"

icy shadow Aug 26, 2022, 9:20 PM

#

t is a thread, yes

merry knoll Aug 26, 2022, 9:20 PM

#

okay best way to explain is this

#

you are creating multiple workers

#

that do stuff on their own

#

did discord crash or was that my internet lmao

lyric gyro Aug 26, 2022, 9:22 PM

#

merry knoll did discord crash or was that my internet lmao

nope

#

that was me too

#

anyways

#

thats usually what a worker do

merry knoll Aug 26, 2022, 9:22 PM

#

merry knoll that do stuff on their own

then you print a number from each

icy shadow Aug 26, 2022, 9:22 PM

#

discord bad

lyric gyro Aug 26, 2022, 9:23 PM

#

icy shadow discord bad

fucking api

#

wrote on python

merry knoll Aug 26, 2022, 9:23 PM

#

which is fine since as you can see the number is exclusive to one thread

granite hound Aug 26, 2022, 9:23 PM

#

also how do you import a reference in intellij?

merry knoll Aug 26, 2022, 9:23 PM

#

import a reference?

granite hound Aug 26, 2022, 9:23 PM

#

also fawe works too right?

icy shadow Aug 26, 2022, 9:23 PM

#

huh?

merry knoll Aug 26, 2022, 9:23 PM

#

dependency you mean?

granite hound Aug 26, 2022, 9:23 PM

#

yeah

merry knoll Aug 26, 2022, 9:23 PM

#

fawe i would stay away from

granite hound Aug 26, 2022, 9:23 PM

#

sorry visual studio c#

icy shadow Aug 26, 2022, 9:23 PM

#

fawe has nothing to do with worldguard

#

what

merry knoll Aug 26, 2022, 9:23 PM

#

it multi threads world edit

granite hound Aug 26, 2022, 9:24 PM

#

i mod slime rancher

merry knoll Aug 26, 2022, 9:24 PM

#

without giving any flying fucks about thread safety

granite hound Aug 26, 2022, 9:24 PM

#

ok ill just use normal worldedit for making the areas

cinder forum Aug 26, 2022, 9:24 PM

#

merry knoll it multi threads world edit

rust have fearless multi threading!

nokotlin

lyric gyro Aug 26, 2022, 9:24 PM

#

what is t.start btw?

merry knoll Aug 26, 2022, 9:24 PM

#

it starts the worker

lyric gyro Aug 26, 2022, 9:24 PM

#

and why is our variable t in the middle of it?

merry knoll Aug 26, 2022, 9:25 PM

#

you are telling the worker go start working

lyric gyro Aug 26, 2022, 9:25 PM

#

variable no

#

i mean thread

lyric gyro Aug 26, 2022, 9:25 PM

#

merry knoll you are telling the worker go start working

move your lazy ass and run the code

merry knoll Aug 26, 2022, 9:25 PM

#

yes

granite hound Aug 26, 2022, 9:25 PM

#

i think to start the specific worker?

merry knoll Aug 26, 2022, 9:25 PM

#

threads are simple when they are contained

lyric gyro Aug 26, 2022, 9:25 PM

#

and why is t

#

in the middle of it

merry knoll Aug 26, 2022, 9:25 PM

#

issues start happening when they have to interact with objects

#

between each other

lyric gyro Aug 26, 2022, 9:26 PM

#

so they work separately?

#

if they interact with eachother

#

something goes wrong

icy shadow Aug 26, 2022, 9:26 PM

#

bro weve said about 10 times that they DONT interact with each other

lyric gyro Aug 26, 2022, 9:26 PM

#

oh

#

ok

icy shadow Aug 26, 2022, 9:26 PM

#

they are all completely separate "processes" in this case

merry knoll Aug 26, 2022, 9:27 PM

#

lyric gyro so they work separately?

since that code is using the thread inside the runnable its making it confusing probably

#

basically you give the thread a runnable (aka a task)

#

and it runs it

granite hound Aug 26, 2022, 9:28 PM

#

also i have this event ArrowTrapEvent = me.gielhauglustaine.deathrun.ArrowTrapEvent; for this Bukkit.getPluginManager().callEvent(ArrowTrapEvent);

merry knoll Aug 26, 2022, 9:28 PM

#

i think i have to give you an actual use case

#

so you get why they are used

#

lets say you have a game and that game needs to get data from the web or a database

lyric gyro Aug 26, 2022, 9:28 PM

#

i still dont understand why is t there

#

did yall explain why

icy shadow Aug 26, 2022, 9:28 PM

#

do you understand oop?

lyric gyro Aug 26, 2022, 9:29 PM

#

what the fuck is an oop

icy shadow Aug 26, 2022, 9:29 PM

#

that's a no lol

#

object oriented programming

granite hound Aug 26, 2022, 9:29 PM

#

object oriented programming

lyric gyro Aug 26, 2022, 9:29 PM

#

oh

#

yes

#

well

icy shadow Aug 26, 2022, 9:29 PM

#

you should get a grip with that before even attempting thread stuff

merry knoll Aug 26, 2022, 9:29 PM

#

icy shadow do you understand oop?

i tried saying you need oop first before jumping into threads but they seem a bit focused on threads

lyric gyro Aug 26, 2022, 9:29 PM

#

Im learning java

icy shadow Aug 26, 2022, 9:29 PM

#

yeah

#

threads are very late-game

lyric gyro Aug 26, 2022, 9:29 PM

#

of course

icy shadow Aug 26, 2022, 9:29 PM

#

you really dont need to worry about that shit rn

lyric gyro Aug 26, 2022, 9:29 PM

#

I know the basics of java

#

dont worry dude

#

I know the basics of java

merry knoll Aug 26, 2022, 9:29 PM

#

if you dont know what "oop" stands for

#

trust me you dont

icy shadow Aug 26, 2022, 9:29 PM

#

event ArrowTrapEvent = me.gielhauglustaine.deathrun.ArrowTrapEvent;
I can't think of a way this is valid code

granite hound Aug 26, 2022, 9:30 PM

#

yeah intellisense said i needed to do that

lyric gyro Aug 26, 2022, 9:30 PM

#

Object oriented programming, means that most of the things you are going to do revolve about objects you create and then run. Is this correct or im stupid

icy shadow Aug 26, 2022, 9:30 PM

#

i highly doubt that

merry knoll Aug 26, 2022, 9:30 PM

#

lyric gyro i still dont understand why is t there

t is the thread dud

#

they made it confusing for you

#

since they combined runnable with the thread

#

a thread takes a runnable and runs it

#

your runnable class has the thread thats running it

#

as a field

#

thats it

granite hound Aug 26, 2022, 9:31 PM

#

well it did event ArrowTrapEvent but it has to equal something right?

lyric gyro Aug 26, 2022, 9:31 PM

#

merry knoll t is the thread dud

https://imgur.com/a/d1yrPGV BUT THESE are different THREADS

merry knoll Aug 26, 2022, 9:31 PM

#

yes

icy shadow Aug 26, 2022, 9:31 PM

#

yes

merry knoll Aug 26, 2022, 9:31 PM

#

thats why we keep saying

#

you need to learn oop

icy shadow Aug 26, 2022, 9:31 PM

#

and each of them has a different t

#

because they are different objects

merry knoll Aug 26, 2022, 9:32 PM

#

they are different instances of theThread class

yall did not respond

lyric gyro Aug 26, 2022, 9:32 PM

#

merry knoll you need to learn oop

what else do i need to learn

icy shadow Aug 26, 2022, 9:32 PM

#

it's a pretty surface-level description

#

but it's not wrong per-se

granite hound Aug 26, 2022, 9:33 PM

#

icy shadow > `event ArrowTrapEvent = me.gielhauglustaine.deathrun.ArrowTrapEvent;` I can't ...

what should i change it too?

merry knoll Aug 26, 2022, 9:33 PM

#

lyric gyro what else do i need to learn

okay you basically need the grasp the idea

#

around instances

lyric gyro Aug 26, 2022, 9:33 PM

#

objects

merry knoll Aug 26, 2022, 9:33 PM

#

when you use the keyword new

lyric gyro Aug 26, 2022, 9:33 PM

#

right? at this point i dont even know anymore

merry knoll Aug 26, 2022, 9:33 PM

you create a new instance
