probably shift + the key left of backspace

hm

how do I know if methods are intensive?
looking at how many lines of code it has :kek:?
or nanoTime?

ivory sleet Mar 23, 2022, 9:18 PM

#

lines wont tell u that much

muted sand Mar 23, 2022, 9:18 PM

#

:(

ivory sleet Mar 23, 2022, 9:18 PM

#

but I suggest benchmarking

#

which can be done in combo with unit tests

#

if you for instance use mockbukkit

#

altho if u use paper (which if i remember you do) then eventexecutors are generated by asm or sth iirc

tender shard Mar 23, 2022, 9:18 PM

#

spring minnow no

The basic Italian keyboard layout as shipped with Windows 7 has no way of typing the backtick (`) or the tilde (~)

#

You can use Alt + 96

ivory sleet Mar 23, 2022, 9:19 PM

#

so being afraid of playermoveevent lag is the least of your concerns

muted sand Mar 23, 2022, 9:19 PM

#

ivory sleet altho if u use paper (which if i remember you do) then eventexecutors are genera...

asm? what's that?

grim ice Mar 23, 2022, 9:19 PM

#

No

#

Well

#

Actually nvm yea

muted sand Mar 23, 2022, 9:20 PM

ivory sleet so being afraid of playermoveevent lag is the least of your concerns

i'll go see what eventexecutors have. thanks!

    public static UUID getUuidFromName(final String playerName) {
        final Player player = Bukkit.getPlayerExact(playerName);
        if(player != null) return player.getUniqueId();
        final Optional<UUID> uuid = Arrays.stream(Bukkit.getOfflinePlayers()).filter(offlinePlayer -> {

this get's the UUID without deprecated methods lol

aight ty xD

#

sec lemme read trough it

tardy delta Mar 23, 2022, 9:27 PM

#

is Bukkit.getOfflinePlayers and array?

granite owl Mar 23, 2022, 9:27 PM

#

all players who have connected once are mapped

#

@tender shard teye ill apply that tomorrow, tbh its like 4-5 years ago since ive worked with the bukkit/spigot api

tall dragon Mar 23, 2022, 9:29 PM

#

tardy delta is Bukkit.getOfflinePlayers and array?

yes

do any of u guys know why @p doesnt work on my server anymore

tardy delta Mar 23, 2022, 9:29 PM

ah thats why

verbal mauve Mar 23, 2022, 9:30 PM

#

been trying to get around the issue but i cant have players teleport to towns with command blocks now and idk if theres a plugin to make @p @r and all that work

can you block the "respawn point set" message or messages like it using a plugin

give lib ideas

maiden thicket Mar 23, 2022, 9:32 PM

replace the last line with uuid.orElse(null)

ez

desert musk can you block the "respawn point set" message or messages like it using a plugin

i'm going to take this as a no

maiden thicket replace the last line with uuid.orElse(null)

orElse is NotNull

maiden thicket Mar 23, 2022, 9:33 PM

tender shard orElse is NotNull

yes

#

u can put null

in the parameter

oh I thought they were using guava's optionals

maiden thicket Mar 23, 2022, 9:34 PM

#

oh lol

#

no stream returns java optionals

tender shard Mar 23, 2022, 9:34 PM

#

in guava somehow null is not allowed in orElse lol

maiden thicket Mar 23, 2022, 9:34 PM

#

yeah i dont use guava except for things i cant remember right now

#

oh right

#

guava comes with Maps and Lists

#

iirc

tender shard Mar 23, 2022, 9:35 PM

#

yeah I was confused because I always use Enums.getIfPresent, and that doesn't accept null

maiden thicket Mar 23, 2022, 9:35 PM

#

ah yeah

#

i think for enums i check using apache commons io

#

its like EnumUtils.isValidEnum

hey so im using this tutorial [https://bukkit.fandom.com/wiki/Developing_a_World_Generator_Plugin] to learn world gen, and in the tree populator section they said to add this method to the main custom chunk generator class:

    @Override
    public List<BlockPopulator> getDefaultPopulators(World world) {
        return Arrays.asList((BlockPopulator)new TreePopulator());
    }```so i did that, but it doesn't seem to do anything and the `BlockPopulator` is gray in my IDE

quaint mantle Mar 23, 2022, 9:38 PM

#

grim ice idk html or css or js or python

thats sad

learn it with mimo 👍

#

cool app

grim ice Mar 23, 2022, 9:40 PM

if you learn languages with apps you're not learning anything

js is very similar to java so should be easy to pick up

what is the treepopulator supposed to do?

lean gull Mar 23, 2022, 9:47 PM

make tree on world

    @Override

        if (random.nextBoolean()) {
            int amount = random.nextInt(4) + 1;  // Amount of trees

                int Z = random.nextInt(15);
                int Y;
                for (Y = world.getMaxHeight() - 1; chunk.getBlock(X, Y, Z).getType() == Material.AIR; Y--)
                    ; // Find the highest block of the (X,Z) coordinate chosen.
                world.generateTree(chunk.getBlock(X, Y, Z).getLocation(), TreeType.TREE); // The tree type can be changed if you want.
            }
        }
    }```

#

imma be honest idk what im doing im just copying the code from the tutorial

grim ice Mar 23, 2022, 9:49 PM

#

then understand it

tender shard Mar 23, 2022, 9:49 PM

#

why are you overriding the old deprecated method?

#

try to use the proper method instead

#

    public void populate(@NotNull WorldInfo worldInfo, @NotNull Random random, int x, int z, @NotNull LimitedRegion limitedRegion) {
    }

lean gull Mar 23, 2022, 9:49 PM

#

wat u mean?!?!?

#

i did proper method >:O

quaint mantle Mar 23, 2022, 9:49 PM

#

tender shard try to use the proper method instead

the new method looks weird

tender shard Mar 23, 2022, 9:49 PM

you should use the correct one instead

#

@tender shard you should update it

that has nothing to do with world generation / blockpopulaters

quaint mantle <@!632994436401594368> you should update it

I have never done anything about world gen lol

lean gull Mar 23, 2022, 9:51 PM

#

i know i'm gonna get ratio'd and 1 million no's but can someone teach me how to do world gen then

tender shard Mar 23, 2022, 9:52 PM

#

I already told you

#

override the proper method

lean gull Mar 23, 2022, 9:52 PM

#

who told me when what why

#

yeah but then i have to change the code and idk how to do that

tender shard Mar 23, 2022, 9:52 PM

#

then print out some text in that method to see if it actually gets called

tender shard Mar 23, 2022, 9:52 PM

#

lean gull yeah but then i have to change the code and idk how to do that

well just look at the parameters

#

obviously you get an instance of WorldInfo, Random, and a LimitedRegion

#

and also x,z but you can ignore that

#

and then, well, obviously you can use the LimitedRegion to change blocks

lean gull Mar 23, 2022, 9:53 PM

#

btw this is not what im tryna do, i don't want to replace the main world of the server, i wanna make a customizable generator where it generates a different world than the main one with like presets and sliders and whatnot

tender shard Mar 23, 2022, 9:58 PM

#

ugh

#

since when does discord support forms

tall dragon Mar 23, 2022, 9:58 PM

#

🤷‍♂️

tender shard Mar 23, 2022, 9:58 PM

#

this is awesome

#

finally I can make people actually force to tell me the name of the plugin they opened a ticket for

tall dragon Mar 23, 2022, 9:59 PM

#

does it support set answers?

#

like where u can choose from 4 answers

tender shard Mar 23, 2022, 9:59 PM

#

only Text fields and paragraph fields

tall dragon Mar 23, 2022, 9:59 PM

#

aw

#

still thats pretty cool

tender shard Mar 23, 2022, 10:00 PM

#

well at least my ticket bot only supports text and paragraph

#

maybe discord actually supports more

hybrid spoke Mar 23, 2022, 10:00 PM

#

can you spam people with it?

#

so there is no escape?

tender shard Mar 23, 2022, 10:00 PM

#

haven't tried, already removed it again lol

#

I'll do some testing tomorrow then change my ticket stuff to ask some questions first

grim ice Mar 23, 2022, 10:01 PM

#

so uh i wanna make a train sort of thing

#

so multiple minecarts followed by each other

#

in the front theres a player that can move all the carts with the keys (w,a,s,d)

#

any ideas?

tender shard Mar 23, 2022, 10:04 PM

#

sounds complicated

#

I don't have any idea lol

desert musk Mar 23, 2022, 10:06 PM

#

reasking this question for the last time: can you suppress minecraft's messages to a player such as when you right click a bed and it says "Respawn point set"

tender shard Mar 23, 2022, 10:06 PM

#

desert musk reasking this question for the last time: can you suppress minecraft's messages ...

I don't think so, it's client sided

desert musk Mar 23, 2022, 10:06 PM

#

alright i see

tender shard Mar 23, 2022, 10:06 PM

#

maybe you can cancel the interact event?

desert musk Mar 23, 2022, 10:07 PM

#

yeah but wouldn't that disallow them from sleeping?

tender shard Mar 23, 2022, 10:07 PM

#

you can make them sleep manually

desert musk Mar 23, 2022, 10:07 PM

#

how's that

#

do tell me because this is something i've been trying to figure out for a while

tender shard Mar 23, 2022, 10:07 PM

#

Player#sleep

desert musk Mar 23, 2022, 10:08 PM

#

what does that refer to?

#

i'm new to plugins

#

oh i see what you're saying

tender shard Mar 23, 2022, 10:08 PM

#

Player has a method sleep(Location, boolean)

desert musk Mar 23, 2022, 10:09 PM

#

ok

#

so you cancel minecraft's default event and just make your own sleep thing

#

smart

tender shard Mar 23, 2022, 10:09 PM

#

exactly

#

but I havent checked if that actually suppresses the message

#

one sec

desert musk Mar 23, 2022, 10:09 PM

#

probably would

tall dragon Mar 23, 2022, 10:09 PM

#

tender shard maybe you can cancel the interact event?

doesnt that still set the respawn point?

#

as would happen when you try to sleep at day?

desert musk Mar 23, 2022, 10:09 PM

#

not when you just cancel the right-click event

tender shard Mar 23, 2022, 10:10 PM

#

cancelling the event still prints a message

desert musk Mar 23, 2022, 10:10 PM

#

hm

#

nvm

#

feel like this is basic enough to be a gamerule

#

bedsSetSpawn

worldly ingot Mar 23, 2022, 10:11 PM

#

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBedEnterEvent.html

#

Should be able to cancel that instead

tender shard Mar 23, 2022, 10:11 PM

#

yeah but that doesn't prevent the "Respawn point set" message

desert musk Mar 23, 2022, 10:11 PM

#

but what if they don't enter it

tall dragon Mar 23, 2022, 10:11 PM

#

@desert musk do you just want to remove the message?

#

or the respawn being set as well

desert musk Mar 23, 2022, 10:11 PM

#

the respawn being set as well

#

but i conceded and decided that I could just hack in a way to sloppily reset the player's spawnpoint when they enter bed

#

but i want a more concise approach

worldly ingot Mar 23, 2022, 10:12 PM

#

There's also this, https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerBedLeaveEvent.html#shouldSetSpawnLocation() if you just want to cancel the bed setting the player's spawn

desert musk Mar 23, 2022, 10:12 PM

#

it should be simple, right?

#

oh hell yeah

#

why couldn't i find that??

#

what magic are you using

worldly ingot Mar 23, 2022, 10:12 PM

#

I don't know if that also does it when a player clicks a bed during daytime, but it might get called?

tall dragon Mar 23, 2022, 10:12 PM

#

actually @desert musk u think u can use PlayerBedLeaveEvent

desert musk Mar 23, 2022, 10:12 PM

#

probably

worldly ingot Mar 23, 2022, 10:12 PM

#

desert musk what magic are you using

desert musk Mar 23, 2022, 10:13 PM

tall dragon actually <@!295573753604341760> u think u can use PlayerBedLeaveEvent

really?

tall dragon Mar 23, 2022, 10:13 PM

#

tall dragon actually <@!295573753604341760> u think u can use PlayerBedLeaveEvent

u can set setspawn to false i believe

Hey guys, what's the right way to use external libraries in your plugin? Specifically, I'm trying to use Apache Cayenne ORM for persisting my data, but its dependency injection mechanism fails when I try to initialize it and execute a sample insert query. I do this in my onEnable hook. It's weird because everything works fine when I try and execute the plugin's jar through the main method, so it must be some runtime quirk of Spigot. I'm using maven-shadow-plugin to package deps into my jar. It seems that, somehow, the initialization code for the DI system is not executed and it has no instances to provide...

true lol

tender shard Mar 23, 2022, 10:53 PM

I think the reason is that

an ItemMeta object doesn't exist

it simply wraps around the NBT stuff etc

so it gets created once you need one

I guess

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

#

It's needed when the types aren't known on the called method ;p

#

That method for example, https://guava.dev/releases/23.0/api/docs/com/google/common/collect/ImmutableMap.html#builder--

#

Static method, declares types K and V, but no args to help imply what K or V is

tender shard Mar 23, 2022, 11:58 PM

yeah makes sense

very weird to read though, I agree lol

#

Just wait until you learn that this is valid as well,

public final class Main {

    {
        this.print("Hello!");
    }

    public void print(Main this, String message) {
        System.out.println(this.getClass().getName() + ": " + message);
    }

}```

Not to my knowledge. That's calculated by the client last I recall

i saw a server do it once im pretty sure

but maybe with packets

#

since it was player specific too

worldly ingot Mar 24, 2022, 12:01 AM

#

If there is a packet for it, I'm unfamiliar with it

young knoll Mar 24, 2022, 12:02 AM

#

worldly ingot Just wait until you learn that this is valid as well, ```java public final class...

That’s just explicitly declaring a parameter that is always there isn’t it

worldly ingot Mar 24, 2022, 12:02 AM

#

Yes

#

So you can annotate it

#

akin to Python's self that needs to be declared in every single method definition. It doesn't imply. Java does

young knoll Mar 24, 2022, 12:04 AM

#

Can’t you also declare arrays in some weird ways

#

Like public int numbers[];

worldly ingot Mar 24, 2022, 12:04 AM

#

Yeah that's valid afaik, though that's just a preference thing

#

C style

#

You can also do jagged arrays. private final int[][] array = new int[3][];

#

Java has some nice oddity features that rarely get used PES_Hypers

young knoll Mar 24, 2022, 12:06 AM

#

Wait how does that work

worldly ingot Mar 24, 2022, 12:06 AM

#

It's an array of variable-sized arrays

#

private final int[][] array = {
    new int[] { 1, 2, 3 },
    new int[] { 4, 5, 6, 7, 8, 9 },
    new int[] { 10 },
};```

#

If that's any help

young knoll Mar 24, 2022, 12:07 AM

#

I see, so you don’t have to define the size of the second array

worldly ingot Mar 24, 2022, 12:07 AM

#

Mhmm

quaint mantle Mar 24, 2022, 12:09 AM

#

tender shard whoa who knew that this is valid syntax? ```java Rocket<String> rocket = hasRock...

// rust translation
let rocket: Option<Rocket<String>, _> = if has_rocket { Some(Rocket::new()) } else { None };

#

or

#

let rocket = if has_rocket { Some(Rocket::<String>::new()) } else { None };

worldly ingot Mar 24, 2022, 12:46 AM

#

lavish hemlock Is there a benefit to reactive programming in Spigot?

You mean like making use of ReactorCore? Likely not. A lot of Bukkit is designed to be operated on the primary server thread, and anything that needs to be asynchronous (like IO and whatnot) can be done with the scheduler. Bukkit doesn't really design anything around asynchronous behaviour outside of events specifically labeled as async, and even that's fairly trivial

#

Unlike Discord APIs that make use of reactive programming patterns because most operations require some query to Discord's REST API

cobalt tinsel Mar 24, 2022, 12:51 AM

young knoll Check the block at the players location

like this?

Sup weebs.

So, I'm trying to get a specific a specific day every year via the following

    private long computeDelayUntilNextStart() {
        LocalDateTime localNow = LocalDateTime.now();
        ZoneId currentZone = ZoneId.systemDefault();
        ZonedDateTime zonedNow = ZonedDateTime.of(localNow, currentZone);
        ZonedDateTime zonedNextTarget;
        MonthDay monthDay = holiday.getMonthDay();
        zonedNextTarget = zonedNow.withMonth(monthDay.getMonthValue()).withDayOfMonth(monthDay.getDayOfMonth())
                .withYear(zonedNow.getYear() + 1);
        Duration duration = Duration.between(zonedNow, zonedNextTarget);
        return duration.getSeconds();
    }

The issue however is... what would be the best way to get the day after without copying the method.
Just return a hash-map with both values or what? This would be used for events that should only last a single whole day

young knoll Mar 24, 2022, 3:42 AM

#

So you want to return both the time stamp for the day itself and the day after

vagrant stratus Mar 24, 2022, 3:43 AM

#

Yes, two different executors.
One to handle starting, one to handle stopping.
I however can't really think of a good way of handling it properly lol

young knoll Mar 24, 2022, 3:43 AM

#

Can’t you just return an array

vagrant stratus Mar 24, 2022, 3:44 AM

#

true. I'll probably have to handle the scheduling differently in any case... hmm

#

public void startExecution() {
        Runnable startRunnable = () -> {
            // some code here, no spoilers!
            startExecution();
        };
        long delay = computeDelayUntilNextStart();
        executor.schedule(startRunnable, delay, TimeUnit.SECONDS);
    }

#

Is how I'm doing it currently 😂

wet breach Mar 24, 2022, 3:46 AM

#

localdate.plusDays(1);

#

change the one to whatever is 1 year + 1 day

#

anyways not hard to get the next day

#

or which ever day 🙂

vagrant stratus Mar 24, 2022, 3:47 AM

#

oof, still doesn't help with how I should handle the runnables though 🤔

wet breach Mar 24, 2022, 3:47 AM

#

well at least you don't have to repeat your code

#

which is what you asked originally

vagrant stratus Mar 24, 2022, 3:48 AM

#

I guess only have the end runnable call startExecution again? 🤷‍♂️

wet breach Mar 24, 2022, 3:49 AM

#

you can have a task or runnable self cancel or self reschedule

vagrant stratus Mar 24, 2022, 3:49 AM

#

oh?

wet breach Mar 24, 2022, 3:49 AM

#

generally works most of the time

vagrant stratus Mar 24, 2022, 3:50 AM

#

How would I go about that?

wet breach Mar 24, 2022, 3:50 AM

#

anyways if a condition is met before the runnable completes or if you just want it to keep getting rescheduled you put the code to schedule the runnable initially at the end of the runnable

#

if that method is located outside of the class where that runnable is at, then you need a method in that class that is static capable of doing it

#

so that the runnable can still invoke it

vagrant stratus Mar 24, 2022, 3:51 AM

#

It would all be in a single class, so that's not an issue

wet breach Mar 24, 2022, 3:51 AM

#

then yeah shouldn't have any issues then

#

this is one of the few times where statics are handy

vagrant stratus Mar 24, 2022, 3:54 AM

#

    private long[] computeStartAndEndDelays() {
        long[] delays = new long[2];
        LocalDateTime localNow = LocalDateTime.now();
        ZoneId currentZone = ZoneId.systemDefault();
        ZonedDateTime zonedNow = ZonedDateTime.of(localNow, currentZone);
        MonthDay monthDay = holiday.getMonthDay();
        ZonedDateTime zonedNextTarget = zonedNow.withMonth(monthDay.getMonthValue()).withDayOfMonth(monthDay.getDayOfMonth()).plusYears(1);
        delays[0] = Duration.between(zonedNow, zonedNextTarget).getSeconds();
        delays[1] = Duration.between(zonedNow, zonedNextTarget.plusDays(1)).getSeconds();
        return delays;
    }

Yea?

#

though.. that does mean it would still have to re-call the method..

wet breach Mar 24, 2022, 3:55 AM

#

where is the code that schedules the runnable?

#

or is that what we are not looking at yet

vagrant stratus Mar 24, 2022, 3:56 AM

#

vagrant stratus ``` public void startExecution() { Runnable startRunnable = () -> { ...

separate method.

vocal cloud Mar 24, 2022, 3:56 AM

#

Could make yourself a pair util

#

wet breach Mar 24, 2022, 3:56 AM

#

delays[][] would work

vagrant stratus Mar 24, 2022, 3:56 AM

#

vocal cloud Could make yourself a pair util

true, but it would still have to be self-updating & self-running.

wet breach Mar 24, 2022, 3:57 AM

#

since you only have 2 items, you can do it with a single array 🙂

#

well technically it is still 2, but just one object

vagrant stratus Mar 24, 2022, 3:58 AM

#

i.e. once one scheduler is finished, it's re-scheduled for the next time.
The fun part however, is this is setup for a specific day only, which means starting & ending that day or at least the beginning of the next lol

#

I can easily half-ass it by breaking DRY and doing an extra method, but I wanna try to make it as clean as possible lol

        delays[1] = Duration.between(zonedNow, zonedNextTarget.plusDays(1)).getSeconds();

    }

Would be following it, however having two methods with almost the exact same code but with a .plusDays(1) breaks it

wet breach Mar 24, 2022, 4:05 AM

#

so use a different api

#

there is like 5-6 different ways you could do this I believe before resorting to some outside API lol

I'm not resorting to an outside API though lol

#

I'm using java API

I could probably find a dependency, but I don't want to add a bunch of dependencies if not needed

wet breach Mar 24, 2022, 4:07 AM

but if this is a task that is delayed by days

#

wouldn't the code I used work without needing all the extra stuff you have?

#

I mean, not sure why the time zone even matters here, if its local anyways

vagrant stratus Mar 24, 2022, 4:09 AM

#

Removing the time-zone in this case removes only two lines of code. It would still leave the need for an array lol

wet breach Mar 24, 2022, 4:10 AM

#

sure, but remove everything you don't need

#

and why do you need an array anyways?

vagrant stratus Mar 24, 2022, 4:10 AM

#

two delays, two different executors. One for starting & one for stopping, seeing as it's a single day thing and must end at the end of the day

wet breach Mar 24, 2022, 4:11 AM

#

you don't know how many seconds in a day?

#

well I guess some people don't have it memorized

vagrant stratus Mar 24, 2022, 4:12 AM

#

Meh, i could just add it to the initial delay but either way I'd still have to deal with two delays and two executors lol

wet breach Mar 24, 2022, 4:12 AM

#

anyways, if you do a lot of networking and dns stuff you get accustomed to knowing how many seconds in 1-2-3 days

#

same with milliseconds

#

why do you need a delay for stopping?

#

86400000ms in a day
86400 seconds in a day

#

in case you were curious

vagrant stratus Mar 24, 2022, 4:14 AM

#

What happens is a single day thing, which means it shouldn't last more than a single day. This means there'd have to be some way to stop it after said day is up

wet breach Mar 24, 2022, 4:14 AM

#

idk what we are stopping

#

but you only need 1 runnable for this

vagrant stratus Mar 24, 2022, 4:14 AM

#

Could be anything, in this case a specific event that should only last a single day

wet breach Mar 24, 2022, 4:15 AM

#

create a condition in the runnable that would return true only when you want said runnable to stop. If condition is met, runnable cancels itself

#

in this case, compare the time

#

if the time reaches a day, stop

#

you know when you started it, and you know already with math when 1 day from that time is.

vagrant stratus Mar 24, 2022, 4:16 AM

#

sure, but the Runnable runs once per specified day.
I could use a while loop, but that's a lot of pointless code execution

wet breach Mar 24, 2022, 4:16 AM

#

vagrant stratus sure, but the Runnable runs *once* per specified day. I could use a while loop, ...

that is fine? Not sure why that would affect the stop condition then if the whole point is to not have the task last more then a day

#

if the runnable isn't running who cares, its not running lol

vagrant stratus Mar 24, 2022, 4:17 AM

#

That my dude is a full 24 hours of non-stop loop just to check to see if it should end

wet breach Mar 24, 2022, 4:17 AM

#

Why would it be looping unnecessarily?

vagrant stratus Mar 24, 2022, 4:18 AM

#

If we're using a single Runnable that runs once per specified day, we'd need a loop to see when it should end

wet breach Mar 24, 2022, 4:18 AM

#

you already said you want it to end when a day has elapsed

#

however I assume the task shouldn't last that long

#

so you can have 2 conditions

vagrant stratus Mar 24, 2022, 4:19 AM

#

It should however, in this case it would be used for a day long event lol

#

i.e. entire day

wet breach Mar 24, 2022, 4:19 AM

#

ok then....I don't see the problem

#

the runnable is going to be looping

#

anyways

vagrant stratus Mar 24, 2022, 4:19 AM

#

No

#

It runs once, then sets a new delay for when it should be ran again

#

All the runnable does is handle starting the event

lavish hemlock Mar 24, 2022, 4:22 AM

#

It's part of the enterprise API, you'd need to import it via your buildsystem

#

Don't use javax.json anyway

#

Use Gson

#

(you don't need to import Gson as a dependency manually either since it's a dependency of MC)

wet breach Mar 24, 2022, 4:23 AM

#

vagrant stratus All the runnable does is handle starting the event

then you are going to want something like this then

#

ScheduledExecutorService executor = Executors.newScheduledThreadPool(2);
Future future = executor.submit(new LongRunningTask());
executor.schedule(new Runnable(){
    public void run(){
        future.cancel(true);
    }
}, 1000, TimeUnit.MILLISECONDS);
executor.shutdown();

vagrant stratus Mar 24, 2022, 4:24 AM

#

Cool, however both the stop and start have to be given new delays for the next time they should be run, not shut down entirely

wet breach Mar 24, 2022, 4:25 AM

#

then tweak it

vagrant stratus Mar 24, 2022, 4:26 AM

#

This would be for things like birthdays and such.
So the executor has to be ran once a specified day with a way to start/stop the event without doing some loop constantly, and then re-scheduled for the same day the following year.

wet breach Mar 24, 2022, 4:30 AM

#

well, unless you plan to not have the application ever quit, then you could just use a single task for that

#

otherwise, you are going to need to save the day it is supposed to run and have some function method upon load up that checks the day

vagrant stratus Mar 24, 2022, 4:31 AM

#

These would be started every plugin startup

#

and I know that lol

wet breach Mar 24, 2022, 4:31 AM

#

then this thing isn't really an issue

#

not sure why you are making it seem like it is harder then it really is

vagrant stratus Mar 24, 2022, 4:32 AM

#

Yea?
I'd still need some way to stop it when needed, shockingly servers can run ages without being turned off

wet breach Mar 24, 2022, 4:32 AM

#

true, so the easiest way is to make use of an event in the server that doesn't happen often

#

like, day night cycle, where every so often you check the day of the actual host

vagrant stratus Mar 24, 2022, 4:33 AM

#

or..i just use schedulers and don't go about it in a hacky method that could result in things start/stopping at the wrong times

wet breach Mar 24, 2022, 4:34 AM

#

it won't?

vagrant stratus Mar 24, 2022, 4:34 AM

#

and it's still unnecessary checking, seeing as the day/night cycle would have no purpose other than this specific use case

wet breach Mar 24, 2022, 4:35 AM

#

and?

#

not sure why that would be a problem

vagrant stratus Mar 24, 2022, 4:35 AM

#

I don't want to do unnecessary stuff when there's a better solution

wet breach Mar 24, 2022, 4:35 AM

#

solves your issue of having an unnecessary task scheduled that only runs once a year or something

vagrant stratus Mar 24, 2022, 4:36 AM

#

and instead I'm doing multiple unnecessary checks a day instead 🙂

wet breach Mar 24, 2022, 4:36 AM

#

as if the day night cycle stops?

vagrant stratus Mar 24, 2022, 4:36 AM

#

It still has to pick a specific point in the cycle to check

wet breach Mar 24, 2022, 4:37 AM

#

event only gets thrown when the cycle completes

There’s an event for that?

wet breach Mar 24, 2022, 4:38 AM

you are only using the event to schedule a task because the event is predictable

That's still more and more unncessary calls 😄

wet breach Mar 24, 2022, 4:40 AM

I guarantee you, the event is more optimal then scheduling a task or two, that do nothing except on a specified day whenever that day is

vagrant stratus Mar 24, 2022, 4:40 AM

#

There could easily be 100s of checks every 20-ish minutes

wet breach Mar 24, 2022, 4:41 AM

#

72

#

the check is a native call

#

since that is what Java would use

#

and adds no extra resources to it

vagrant stratus Mar 24, 2022, 4:41 AM

#

Dude, the limit depends on how many events there are

wet breach Mar 24, 2022, 4:41 AM

#

since your method only compares the current time with the time you want to run something, if they don't match

#

don't do anything

wet breach Mar 24, 2022, 4:42 AM

#

vagrant stratus Dude, the limit depends on how many events there are

there is 72 day night cycles in a 24 hour period in minecraft

#

the event doesn't get ran if someone changes the time either

#

since the way MC commands work, it rewinds time, not make it go forward

#

but that isn't really relevant because a 1 line method isn't resource intensive to begin with

vagrant stratus Mar 24, 2022, 4:42 AM

#

Cool, so 72 times + however many other calls that need to be made.
Bare minimum it's still 72 unnecessary calls

wet breach Mar 24, 2022, 4:43 AM

that don't add much to the resources, not exactly what you are worried about here o.O

TimeSkipEvent *

young knoll Maybe I should do some PRs again

make one for day/night changes 🙂

young knoll Mar 24, 2022, 4:53 AM

#

What exactly would that entail

wet breach Mar 24, 2022, 4:54 AM

#

basically would just at certain tick intervals, throw the event because it is day or it is night

#

or full mc day completed one of those

#

I mean the server already keeps track of that so not like much needs to be added except that an event gets thrown lol

young knoll Mar 24, 2022, 4:55 AM

#

Yeah full day competed should be easy

wet breach Mar 24, 2022, 4:55 AM

#

since the day/night cycle is pretty regular it would just be a handed utility in the server you could use instead of scheduling stuff

#

since that event would happen at regular intervals that would be predictable 🙂

young knoll Mar 24, 2022, 4:56 AM

#

Yeah

#

Gotta figure out where to inject that tho

vagrant stratus Mar 24, 2022, 4:57 AM

wet breach Mar 24, 2022, 4:57 AM

young knoll Gotta figure out where to inject that tho

might help to use the api method that lets you get the time in MC

could be implemented in the server where you might need to inject into

young knoll Mar 24, 2022, 4:57 AM

True

#

Thankfully IDEs are magical and can find usage

vagrant stratus Mar 24, 2022, 4:58 AM

guess I could just half-ass it and wait for the maybe eventual PR that's like Yo, fix this shit

#

lol

vagrant stratus Mar 24, 2022, 5:00 AM

vagrant stratus Mar 24, 2022, 5:02 AM

#

wet breach I mean, not sure why the time zone even matters here, if its local anyways

Use ZonedDateTime class to handle Time Zone specific calculation including Daylight Saving issues.

ZonedDateTime is an immutable representation of a date-time with a time-zone. This class stores all date and time fields, to a precision of nanoseconds, and a time-zone, with a zone offset used to handle ambiguous local date-times. For example, the value "2nd October 2007 at 13:45.30.123456789 +02:00 in the Europe/Paris time-zone" can be stored in a ZonedDateTime.

wet breach Mar 24, 2022, 5:04 AM

I know what it is for. Just don't think time zone matters, unless this is something the user can schedule?

vagrant stratus Mar 24, 2022, 5:04 AM

#

Might allow it

wet breach Mar 24, 2022, 5:04 AM

#

if this isn't something the user schedules then the time is always local to the application

vagrant stratus Mar 24, 2022, 5:05 AM

Kinda need something that works first before allowing it to be configurable..

vagrant stratus Mar 24, 2022, 5:54 AM

Guess I could also just reset the list of active events every day, regardless of if there's one running or not lol

#

Can't really think of a better method xD

wet breach Mar 24, 2022, 6:13 AM

#

with something like this, I would probably just utilize the OS

#

linux already has a system in place for such things

#

windows does too but a bit more pain to access

#

setup a cron job while the application is alive, if its shutting down remove the cron job

vagrant stratus Mar 24, 2022, 6:15 AM

Cool, doesn't deal with the java code...

#

I'm pretty sure you forgot that part when writing that response

wet breach Mar 24, 2022, 6:21 AM

#

I didn't forget about cron jobs lol

#

most people just want something in code so I generally provide to facilitate that

vagrant stratus Mar 24, 2022, 6:21 AM

#

cron jobs don't run java code afaik 😉

wet breach Mar 24, 2022, 6:21 AM

#

personally I am all for dropping out of java if there is something better while also being able to use it from java

wet breach Mar 24, 2022, 6:25 AM

#

vagrant stratus cron jobs don't run java code afaik 😉

not directly no

#

but you can make use of unix sockets however which both can access

#

for old java versions similar thing would be using memory mapped file to communicate with each other

#

with unix socket you are always listening for input

#

cron job sends input, voila you now do something

vagrant stratus Mar 24, 2022, 6:26 AM

#

...so...an even hackier way

wet breach Mar 24, 2022, 6:27 AM

#

it isn't an hack

vagrant stratus Mar 24, 2022, 6:28 AM

#

Compared to pure java ways yes

wet breach Mar 24, 2022, 6:28 AM

#

don't see why it would need to be pure java

#

just because you drop out of a language doesn't mean it is a hack

#

cron just invokes commands at specidied times, which can include bash scripts

#

bash supports using utilities to connect via a socket even unix ones

#

java supports unix sockets since Java 17

#

there is no hack in that, you didn't change how either of them work

#

all I did was identified a medium in which both could communicate with each other

#

and there is 2

#

unix sockets or memory mapped files

#

which memory mapped files are actually designed to be used by more then just the process that created it

vagrant stratus Mar 24, 2022, 6:31 AM

#

(of a piece of computer code) that provides a quick but often badly designed solution to a problem, allowing the user to continue working until a better solution can be provided. It's just a hacky workaround.

wet breach Mar 24, 2022, 6:31 AM

#

I don't see how it is badly designed

#

cron jobs are native to linux, its like saying lets not use cruise control in a car because you can just push the gas yourself

smoky oak Mar 24, 2022, 6:32 AM

#

all temporary workarounds just become permanent at some point

vagrant stratus Mar 24, 2022, 6:32 AM

I'd have to do extra work to support windows, and it means I'd have to test on both OS's

wet breach Mar 24, 2022, 6:32 AM

#

it doesn't need to be temporary, cron job is built into linux, specifically designed to do something at a specified time

#

in this case all you need it to do, is just tell the java process hey do something

golden kelp Mar 24, 2022, 6:33 AM

unix socket

#

this is something implemented in many programs

where they use unix socket or memory mapped file for timed events

from the OS

#

anyways, its your application 🙂

#

not that I use it anyways, just this is the primary reason I don't use other people's stuff as well. I wouldn't bother holding an object for something that will happen 1 year from now

#

it is just a waste

#

you have the OS that already checks the scedule/tasks and it probably will do it more efficiently then the JVM itself

#

and you are not wasting space with a useless object for however long

vagrant stratus Mar 24, 2022, 6:42 AM

wet breach it is just a waste

You could say the same for your idea, since the socket would have to be running all the time.

Vault does a lot though that would require being such

vagrant stratus of course, however it's still a `proper` lib 😉

proper libs don't do anything on their own

#

library is different from an API

vagrant stratus Mar 24, 2022, 7:15 AM

#

some libraries do have to load spigot stuff though 😄

wet breach Mar 24, 2022, 7:15 AM

#

yes and they can when a plugin needs it

#

said plugin would grab an instance of the library which then allows it to do such

vagrant stratus Mar 24, 2022, 7:15 AM

#

or they just be a plugin and load that stuff on load that way a plugin isn't waiting for that to all be initalized

wet breach Mar 24, 2022, 7:16 AM

The it isn't a library in that case

not a proper one anyways

As the name implies, it is the Base for making a plugin

ok , so i should get the door in this way?

and then use BlockState?

yes, because then its a matter of doing door.setOpen(boolean);

I do recall there sometimes being some weird bugs with doors requiring to set the halves XD

You need to cast to bisected and get the other half that way
