I can't believe c# doesn't have a single line random number generator

#

this is a betrayal of the highest order

mortal hare
#

I'm pretty sure JavaPlugin class just uses its own classloader's getResourceAsStream in this method internally

#

that's just an alias

#

iirc

manic furnace
#

How does sqlite Work? Is it a server like MySQL?

torn shuttle
#

it's very, very similar to mysql

vagrant heath
#

Disagree

#

One is a real database, the other one is filebased

#

@manic furnace i assume the not being a server is what you are asking

manic furnace
#

OK so MySQL is a real database?

quaint mantle
#

Yo

vagrant heath
#

Yes

#

Or rather a real database server

#

They are both databases

quaint mantle
#

I want to make a gui and if the next that is here, there must come a new gui

#

How

manic furnace
#

So which one is better in performance?

vagrant heath
#

Depends on what you need

manic furnace
#

A lot of interactions

quaint mantle
vagrant heath
#

In different threads?

ivory sleet
#

CoderTheDuggy, I’d certainly say that mysql/postgre is much more powerful

manic furnace
#

Ok

vagrant heath
#

^

#

But it may not be the tool for the job

#

Your use case would be good to know

quaint mantle
#

I want to make a gui and if the next that is here, there must come a new gui Guys, how

vale ember
#

if the server is not so big sqlite is the best choice

#

it's far more simple

vagrant heath
#

Sqlite is great for internal storage

#

As you dont occupy any ports and network

#

Just disk read and write bandwidth

#

Lq how about an inventory?

vale ember
vagrant heath
#

A reasonable assumption for sure

manic furnace
#

So it's just like writing to files?

vagrant heath
#

Sqlite is literally you writing to a file

#

Its just abstracted away through some library

#

You could just as well write a txt or json, but sqlite is faster and nicer to work with

manic furnace
#

Ok because in the moment i am using files lol

#

OK i add both options to my plugin so the user can decide

vagrant heath
#

Json and txt are kinda write only, for an edit you read, change and write, right?

manic furnace
#

Yes

vagrant heath
#

Thats ok for settings

#

But not for active data

mortal hare
vagrant heath
#

It really doesnt matter which sql server

#

Let's not devolve into a religious war on sql servers

#

Alltough im on mariadb side as well

#

@quaint mantle have you looked for any libraries? Im sure there is good spigot UI libraries

#

anyway, I didnt even get to ask my question yet:

I am trying to:
interfere with dispenser events and stop it from dropping its item. Not like cancelling the event, but just like empty buckets pick up water without throwing the bucket on the floor

spiral bramble
#

sql.execute("CREATE TABLE IF NOT EXISTS ?fluxcredit (uuid VARCHAR(225),username VARCHAR(225),credits INT) ENGINE=INNODB;", "fluxcore_");

This should replace the ? with fluxcore_ in the string correct?

blazing scarab
vagrant heath
#

Im gonna assume JDBC?

#

And no, im pretty sure you can only have lonestanding ?

#

else you are back to funny SQL injection

#

wait no JDBC looks different

uhm

#

thats like

#

the best way to stop movement

#

but i prefer potion effects

#

so players dont get that draggin effect

mortal hare
#

set walkspeed to 0

#

and cancel event

onyx fjord
#

that works too yea

vagrant heath
#

LQ you are trying to make a GUI, have you looked for any libraries that may accomplish that? If not, may I recommend looking into how to open inventories for players and getting info from them?

#

Because "it needs to make new GUI" does not really provide any info whatsoever

#

string concatenation?

#

if prefix is player controlled its over

tender shard
#

so? if the admin decides to inject sql into their own database, it's their fault

#

the admin literally has 100% control over the DB anyway

vagrant heath
#

the usecase wasnt clear to me there

#

but yes

tender shard
#

seems like prefix is sth like "wp_" used by wordpress by default

#

if an admin decides to use db-prefix: "prefix; DROP DATABASE asd;" it's a bit stupid but not really a security concern because obviously they have the credentials anyway

gritty urchin
vagrant heath
#

Why not just `sql.execute("CREATE TABLE IF NOT EXISTS ? (uuid VARCHAR(225),username VARCHAR(225),credits INT) ENGINE=INNODB;", prefix+"fluxcredit");

gritty urchin
#

literally lags when i turn my head

warped panther
#

use anvil gui to take a string

vagrant heath
#

or would that not work

vale ember
#

well i am using playermoveevent and it don't lag

gritty urchin
#

or try to move

#

infinite lag back

tender shard
gritty urchin
#

when i try and move my head

#

it spazzes out

spiral bramble
vagrant heath
#

I wasnt sure

tender shard
#

well don't blindly cancel the event, but only cancel it if the x,y,z has changed

sharp flare
#

Thats an easy hash map cancellation

tender shard
tender shard
vagrant heath
#

just adding the string outside of the template?

manic furnace
#

When i write a program to use SQL, can I use it in MySQL and PostgreSQL?

vagrant heath
#

generally no

mortal hare
#

Different SQL engine syntax could be different

vagrant heath
#

practically no

spiral bramble
mortal hare
#

but for example MariaDB and MySQL are inter-compatible generally with each other

sharp flare
#

If the player moves, from the last location saved in a hashmap then tp him back or just cancel the event for Christ sake

vagrant heath
#

SQL norms are a mess, and you are going to be using two completely different engines anyway

tender shard
# 
    @EventHandler
    public void onMove(PlayerMoveEvent event) {
        if(!isFrozen(event.getPlayer())) return;
        if(!hasMoved(event.getFrom(), event.getTo())) return;
        event.setCancelled(true);
    }
    
    private static boolean hasMoved(Location loc1, Location loc2) {
        return loc1.getX() != loc2.getX()
                || loc1.getY() != loc2.getY()
                || loc1.getZ() != loc2.getZ();
    }
#

no map or anything needed

#

sometimes adding backticks ` helps for column names

tender shard
#

if you want to use ?

#

preparedStatement.setString(1,prefix+"fluxcredit");

blazing scarab
vagrant heath
#

its not JDBC

blazing scarab
#

Much much cleaner

spiral bramble
blazing scarab
#

pretty sure that uses prepared statements

tender shard
#

oh you're using some lib. if that's an example from its docs, it probobably already uses prepared statements

spiral bramble
#

^^ Its open source, just checked and it does use PreparedStatements

vagrant heath
#

what sql server do you have?

tender shard
#

hm maybe prepared statements don't work at all with table names

spiral bramble
tender shard
#

however I wouldn't worry about it. since the table name cannot be changed by user input, no prepared statements needed

tender shard
#

you can totally just insert the tablename yourself as long as it's not consisting of ANY player input

vagrant heath
#

depends on what weird stuff the library does, if it goes through jdbc you are right

midnight shore
#

Hi guys, I have a String which is actually a List of string translated to a string, (Example: I have List that contains A and B, my String will be "A☇B" [As "☇" is the symbol that defines an end of a string and the start of another one]). How can i retranslate this into a List? is there any way to break it into other strings for every "☇" symbol that it contains?

Hope you understand.

vagrant heath
#

.split

tender shard
# 
"CREATE TABLE IF NOT EXISTS `" + prefix + "pluginname`;"```  is 100% fine to use
spiral bramble
vale ember
#

"I want to make a gui and if the next that is here, there must come a new gui" huh?

midnight shore
quaint mantle
vagrant heath
#

as a player can only have one inventory open

quaint mantle
#

Nooo

vagrant heath
#

and spigot UI is mostly implemented as inventory

#

spigot can not run code on the client

vale ember
#

and chest as first

vagrant heath
tender shard
#

I guess they just want to have a paginated GUI

vagrant heath
#

(also then you could just split the chest in half lol)

vale ember
spiral bramble
# 
if (date == 15-02-222) {add stone}
if (date == 16-02-222) {add cobblestone}

Thats my only guess to what you want?

vagrant heath
quaint mantle
#

But the gui must change, they dont need to open 2 inventory's but if the command is ./shop and they use ./shop 15-02-2022 23:59 She wil get GUI 1. And if they run 1 time more round 16-02-2022 00:00 She will get Gui2

vagrant heath
#

then just check the date?

quaint mantle
#

😂

vagrant heath
#

I dont get your usecase

#

you want to show different things at different dates

#

is my only guess

#

then get todays date and show different things

spiral bramble
# quaint mantle But how

LocalDateTime now = LocalDateTime.now();
EDIT - This will return the date-time of the local machine the server is hosted on

tender shard
#

get current date, check if it's date X, show item X, if it's date Y, show item Y, where's the problem?

quaint mantle
vale ember
#

you should have something like map with date as key, and item as value, and depending on the commands argument get right item, create inventory, put item in it, open inv for player

#

nothing hard

midnight shore
vale ember

if you know basics

I have a gui system

midnight shore
# vagrant heath ohhhh

I can only save a STRING type. But i want to save a List of strings! The only way i can think of is by adding them into one single string using some symbol to define a string end end a string start. (I'm saving this to a PDC so i cannot even modify it to use the Array)

spiral bramble
ivory sleet
#

Custom PDC type?

vale ember
# quaint mantle Yes

you create a map Map<Date, ItemStack>, in command, you create inventory, get right item from that map, put it in inventory, open it for player

quaint mantle
vale ember
#

if you use plain inv

vagrant heath
#

ok lemme check again: you want to turn a List<String> into a String?

vale ember
#

if you have gui system it depends

Can you guys send a example

blazing scarab
quaint mantle
vagrant heath

no because your usecase is not clear at all

blazing scarab
#

The split method has a problem: it breaks when you have a string which contains the separator

vale ember
vagrant heath
spiral bramble
# quaint mantle ?

Seeing you're editing a 'ShopPlugin' project, I'm assuming you want different items to appear in the shop on different days?

blazing scarab
#

The lib i sent avoids that problem by storing string array efficiently as bytes

quaint mantle
vale ember
ivory sleet
#

Or stick with a custom pdc type like gepron1x suggested

quaint mantle
#

I Have a tread

tender shard

guys we already have a thread for the string list pdc thing

#

I'd use nbt, I just hate PDC

because nbt is a good format lol

BLOCK_MARKER?

vale ember
#

/Lqrss no offence, that's just super basic java, not spigot

tender shard
mortal cedar
#

and this has a BlockData to determine whether it is barrier or light effect?

tender shard
#

IIRC Particle has a method getDataType

mortal cedar
#

okay I'll try to figure it out

#

thats enough info for me ^^

tender shard
# 
    @EventHandler
    public void onMove(PlayerMoveEvent event) {
        //System.out.println(Particle.BLOCK_MARKER.getDataType());
        event.getTo().getWorld().spawnParticle(Particle.BLOCK_MARKER,event.getTo(),5, Bukkit.createBlockData(Material.GOLD_BLOCK));
    }

tender shard
#

np 😄

#

it's a bit annoying that the particle javadocs don't show the actual particle data class

so you always have to print out Particle.WHAT_EVER:getDataType() to know what it actually needs

Ok so my usecase: custom dropper behaviour, I want to not drop a bucket when there is a cauldron in front and instead get the water into the bucket

#

I already have the water level in the cauldron and all that, but the event does not differ between dropped and not dropped items

vale ember
#

what if you cancel the event and dispatch a new one with same data? i think it won't affect vanilla

vagrant heath
#

yeah cancelling is probably the way to go then

#

just means I need to implement the noise and smoke custom

#

but that clears up my understanding of events, thx

alrighty

spiral light
#

oh nice some fancy changes i can see there

vagrant heath
#

ok yikes

#

when a bucket is dropped the velocity is the items velocity.
when a bucket is not dropped but it collects water the velocity is the block position

#

thx mojang or MS or whoever

sleek pond
#

What

vagrant heath
#

depending on if there is water in front of the dispenser or not, it either drops the bucket item or just fills it, yes?

sleek pond
#

Right

vagrant heath
#

and if it fills it, then the event information on the dispensed item velocity is instead the coordinates of the block it picks up

sleek pond
#

And so what's the problem

vagrant heath
#

it cursed

#

and doesnt make any sense at all

sleek pond
#

Picking something up shouldn't even have a velocity

spiral light
#

probably

sleek pond
#

And I can't think of a usecase where you'd want to use that velocity

vagrant heath
#

yes, so why microsoft

#

but I figured out how to do my stuff

spiral light
#

the api is not microsoft O.o

vagrant heath
#

i mean i dont know when stuff was written

#

oh wait team is still mojang, right?

#

my bad

spiral light
#

what ?

vagrant heath
#

turns out the smoke and sound doesnt disappear when I cancel the event (?)

#

i dont understand dispensers in spigot

#

if anyone ever figures out how dispensers work please message me

spiral light
#

the stuff written in the api is not mojang or microsoft... its mostly md_5 or the army of helping developers behind him ?

if someone who made the event thought its a good idea to set the velocity to the blocks location when its a bucketfill-event it wasn't microsoft or the nms code at all

spiral light
vagrant heath
#

but I guess I gotta decompile and look whats going on if I really want to find out

finite inlet
#

HI! Have never gotten this issue before but tried setting up a server to test a plugin im working on, anyone knows why I get this error when running my bat file?

\Servers\1.18.1 Bungeecord\Servers\Lobby>java -Xmx1024M -Xms4024M -jar server.jar nogui
Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size
tender shard
#

and the min ram to like 4GB

#

obviously 4 is more than 1

#

you probably confused Xmx and Xms

#

(although tbh the error message is quite obvious on what the problem is 😛 )

finite inlet
#

Wait what, I thought I changed that well thanks

wet breach
#

not sure why you would need to decompile it lol

#

also items are a type of entity and thus can have velocity

vagrant heath
#

im complaining about the case where no item is dropped

#

like when a bucket picks up water

#

then instead of the velocity it is somehow the coordinates

#

not that it matters for my usecase, its just really really weird

#

Ok another question, I just noticed that Dispenser doesnt extend Block, so my casting approach obviously wont work. How do I go about getting a container from a Block?

tender shard
#

not Block

vagrant heath
#

yeah just arrived at that as well

tender shard
#

Dispenser dispenser = (Dispenser) block.getState()

vagrant heath
#

thx

neon nymph
#

Does bungee use offline or online UUIDs?

spiral light
#

depends on settings i guess

neon nymph
#

What settings?

dusk flicker
#

If bungee is online or offline

#

That setting

spiral light
#

online_mode: true or false

neon nymph
#

Oh, bungee also has that option huh

dusk flicker
#

Yep

wet breach
neon nymph
#

Never knew. Thought online mode should always be false

#

I'd assume that's for the actual servers now

dusk flicker
#

On the spigot servers it has to be off for using bungee

#

For online mode tho it has to be the default of on in bungee

#

texturepack on github lol

finite inlet
#

yeah, but how would I get the server download the github repo, zip it and then replace the old one? 👀 Any tips on what I should read for this?

vagrant heath
#

there is 2 routes in front of you

#

1 is git clone shell script of death

wet breach
tender shard
#

github has a download zip function

#

it automatically zips the whole repo

wet breach
#

there is that too

tender shard
finite inlet
#

alright! Thanks!

tender shard
#

so you can basically just provide that link as resource pack url

vagrant heath
#

if teh whole repo zipped is what you want then http get for that zip it is

#

otherwise im sure there are some git wrapper libraries

tender shard

#

yep! That will work 😄

I have a question for which I sadly think I know the answer. When canceling a BlockDispenseEvent the inventory im accessing is already missing the correct items (this is what I want). However due to me canceling the event the item is added back after my event handling is done. is there any way to prevent this?

tender shard
#

you could manually remove the item after the event

Hello, I'm not sure I'm in the right place, despite hours of research, I can't find a solution, so here's my problem; the server can't find my main class when I use Cauldron API, while with a Bukkit server, the plugin works perfectly. What should I do?

There are no performance gains from 1.8.

well no shit it'd perform better, theres way less stuff on 1.8

thats a pretty unfair comparison considering the feature difference

Modern iterations of the JVM have improved bytecode, probably new JIT optimizations, and a bunch of different, more optimized GCs than the basic CMS.

For reading

Quick question here, I'm trying to modify a block from a certain world onEnabled. World is not loaded so I went to world load event. It still appears as if the world is null even tho it is on the WorldLoadEvent and it is that exact world. How do I wait for the world to finish loading or I just schedule the task? If I do, how long should it be or that changes?

Concurrency and not relying on EOT

i am still getting if you left click midair it is erroring

You cannot write the size because the underlying collection may change, so that is the second-best guess
Idk, you probably could do better things, I know

Fine, EOF

I get the idea behind the whole byte separator thing

(and also likely more efficient since it allows you to create a collection with an initial size)

Hi guys is there any way to get a random stone block in ChunkLoadEvent?

iterate over all blocks in the chunk below y=59 and check if they are stone, if one is stone select a random number using Math.random() and check it to a certain value, if its below the value return the stone block

Casting to Playe there does nothing because getPlayer already returns a player.

Your first condition reads as "if getState returns not not null" which can be simplified to just "if getState reurns null"
and would therefor always throw a NullpointerException. getClickedBlock() will also sometimes be null leading to another
NullpointerException.

Dont use deprecated methods. They are deprecated for a reason and have a replacement.

Your e.setCancelled() calls make no sense. Also your intendation is abysmal and makes this really hard to read. Use ctrl + alt + L to auto format your code.

also they are casting the block to sign

and then 10 lines later check if it's actually a sign

I mean

#

as long as you adhere to the interface its fine?

You might be thinking that it is premature optimisation, but I don't quite enjoy having a GC intervall of 14 secs on an empty server after it runs for an hour

#

cant you adjust that with a jvm arg presupposing one exists

wtf are you doing that there's so much to clean up to

I have an issue,

My scoreboard doesn't wanna update and its in a bukkit runnable and set for the on join method, So im just curious, how can i fix this?

#

This is my code

How to cancel Villager interact event so inventory wouldnt show

quiet ice
# 
    @Nullable
    public PlayerAttachedScore getOwner(@NotNull UUID world, int x, int y) {
        return leaders.get(new WorldPosition(world, hashPositions(x, y)));
    }

Once for every chunk every 5 seconds is (for a reason I cannot understand) fast but (for a reason I understand) taxing on GC

That is not the default eclipse font

manic crater
#

well i never touched it so idk

#

anyway

quiet ice
#

That is just the absence of antialias

tender shard
#

well what do you expect your code to do

manic crater
#

moving past that, do you know why the bukkit runnable wont refresh the scoreboard?

manic crater
tender shard
#

your runnable doesn't do anything useful besides setting the same scoreboard to the player all the time

....

tender shard
#

all you do is "player x uses scoreboard y" every time

manic crater
#

i thought resetting it refreshes it?

tender shard
#

what do you mean with "refresh"?

manic crater
#

like okay

tender shard
#

you never change any values on the scoreboard

so I have no idea what you want to be "refreshed"
