Did you just use 'b&' as short for banned
yes

what did happen to magma

did he ping wiz one too many times
tbh given the lack of explanation from the mods it's probably a bullshit reason
aka once

Well given it's wiz it probably was
ping him and ask 

that's a cancerous name
look who's talking
at least mine's legible
¯_(ツ)_/¯
inb4 wiz
especially given your username
:^)
definitely one lurking
which only proves my point about magma tbh
lemme guess they changed ur nick and you reset it
they ain't telling cuz they can't backup
then you got kicked
:>
interesting
no message what so ever
so it was wiz
nice
wow

from the amount lazyness you can tell which mod it was

wonder why
Waddafuq
perhaps the new username tells you why
but I'm just here to get a few helpful tips so I'm not fixing it
does waterfall work with various IP's?
that'd be fun
finish him off wiz 
I have a helpful tip
wiz did say he was going to bed, not that he was going to sleep.
inb4 he's lurking on his phone.
Change your name to be less obnoxious if you don’t want want to get kicked :aaa:
alright any suggestions?
How about „accursed shield“? 
I think this works out nicely

yesterday we dipped into 10 tps with 8 players lol
all I needed to do was stop limiting NPC spawns ;]
8tps, yis no issue
it wasn't because of 1.14 tho lol
i wish you werent
yuck


Hello world
Hello world but it's done via particles in the air.
I'm going to die of old age before I figure out how to make NPCs sleep in sponge
it generates a plot of land that you can't use because it's too buggy
make me a sandwich
wait no you're not a wamen
only wamen make sandwiches, and that's the only thing they do
tf is going on here
sandwiches 
do i need to kick someone first thing in the morning
you would've done it anyways
wiz you don't need to meet your daily kick quota first thing when you wake up
i do if city is gonna be like that

isn't he like that every day
is that an argument for kicking him?
kenny was talking bout ur ass
whatever you want it to be


no I did indeed mean city
rip
leaf I have a project for u
yes
yikes
learn sponge and figure out how to make their retarded NPCs fucking go into the sleep position

Impossible project
from what I can tell it's kinda just not possible
oO
here's the mega big brain pro tip about mc
Killem and they go night night ?
if ur fucked and don't know what method does what u want
find some piece of code that obviously does it
They use a dummy player alternative that doesn't extend EntityPlayer so I can't send the SPacketUseBed packet.
it has an entityid however
for sleeping it's probably some bullshit in player interact handling
so follow the code using that packet
the thing tho is players can just create the packet
I literally cannot create the packet with their npc class
it'll use some method to get the player to sleep
what
it's legit some big brain retardism
public SleepResult trySleep(BlockPos bedLocation) {
SleepResult entityplayer$sleepresult = super.trySleep(bedLocation);
if (entityplayer$sleepresult == SleepResult.OK) {
this.addStat(StatList.SLEEP_IN_BED);
Packet<?> packet = new SPacketUseBed(this, bedLocation);
this.getServerWorld().getEntityTracker().sendToTracking(this, packet);
this.connection.setPlayerLocation(this.posX, this.posY, this.posZ, this.rotationYaw, this.rotationPitch);
this.connection.sendPacket(packet);
CriteriaTriggers.SLEPT_IN_BED.trigger(this);
}
return entityplayer$sleepresult;
}```
@static badge

it's literally just send the packet and move to bed
super.trySleep(bedLocation)
can't
it's not an EntityPlayer or EntityPlayerMP
so even if I could call it, I don't have an EntityPlayer to pass into the packet's constructor
sending the packet anyways wont do anything
Er, wut r u tryna do?
make an npc sleep
make NPCs sleep in sponge
Sleeping is some property on the entity
probably a datawatcher field...
tbh i much prefer npcs that arent players
that causes no shortage of bullshit in bukkit stuff
EntityHuman extends EntityCreative
Human extends Humanoid extends Living
yeah I'd prefer it if I could make it do everything that I want
instead of spending 5+ hours trying to make them fucking sleep 
it's a pose
public void entitySleep(BlockPosition blockposition) {
if (this.isPassenger()) {
this.stopRiding();
}
IBlockData iblockdata = this.world.getType(blockposition);
if (iblockdata.getBlock() instanceof BlockBed) {
this.world.setTypeAndData(blockposition, (IBlockData) iblockdata.set(BlockBed.OCCUPIED, true), 3);
}
this.setPose(EntityPose.SLEEPING);
this.a(blockposition);
this.d(blockposition);
this.setMot(Vec3D.a);
this.impulse = true;
}
there
Player NPCs in Bukkit aren't even that baddddd
you can also follow methods like isSleeping
except you go backwards
wat writes to this
aren't that bad
you know citizens replaces the tracker entry
nothing related to poses in EntityLiving or EntityLivingBase
(which is what that latest comment on the tracker pr is about)
Coz it's all the way at the top
leaf what class is that method on
there's fuck all for beds or sleeping in EntityLiving or EntityLivingBase
this is 1.12 so might be diff
but like
0
u lokin for a NSFW channel der?
ok
Vic u suck
leaf ur retarded
well vicarino
do the same thing I did
We're on spigot mappings, we're not gonna fire up sponge stuff :L
yeah ik
EntityLiving might be EntityInsent
find what sets it to true
there is a isPlayerSleeping on EntityLivingBase
it's hardcoded to always return false
it's overriden
yes
so it's not always false
but not by anything Human extends
someone else bitched about this like a year ago
think I'm gonna bitch about it again
nothing's gonna be done about it because they're working on 8
but
¯_(ツ)_/¯
just use bukkit instead u noob
and do stuff like replacing tracker entries 
ezpz lemon sqez
what if
no
I use mixins and just fuck with it
you didn't use sponge
ur retarded
yes
also I don't use citizens because I got paid to make my own npc shit and it's running very nice indeed
tbh this bullshit is why I'm over here in bukkit land
ngl there's been so many times I wish I could just patch my way through
god fuck
imagine writing something for the server
and receiving reports of it breaking fucking mixins
fuck
hire me
plz update our shit to 1.15 I pay u $1/h
that's 3 weeks of pay
lol yeah I make like $1000 every minecraft version just for updating nms in our npc framework
this fucking thing
i stg if making the npc sit is making it invisible / not spawn
oh I forgot to uncomment something
haHAA I LOVE THIS
Höt
this plugin would've been done like
in 2 hours tops if I could just make these fucking things lie down
IT'S NOT EVEN SITTING
ah yes the key only works on doggos
just rotate 90 degrees 
whatever time for plan b
I was gonna make a death corpse plugin but instead I'll just make it so the phantom entity attacks the player and the player has to kill it to get their shit back
fuck the players
make it a chest
no fuck chests
do u know how many graveyard / death chest plugins and mods there are
and the reason there's no phantom one is cuz that's retardo
ur retardo
ur retardo
ok how do I make this piece of shit attack me
waiting
????????
phantom npc as in
not real u retard
Human npc = (Human) location.getExtent().createEntity(EntityTypes.HUMAN, location.getPosition());
THAT'S NOT A PHANTOM REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
ur pepega
such an epic emote
lmao
Ima become a professional singer
me: is sad PlotSquared gets no contributions
our code: https://github.com/IntellectualSites/PlotSquared/blob/v4/Core/src/main/java/com/github/intellectualsites/plotsquared/plot/commands/ListCmd.java
I don't know how the fuck this plugin even manages to start

pure luck?
probably, yes
i fell into depression, city
that's fucking it
i'm gonna quit programming and become professional welder
😠
programming is for rarts anyway
not stealing the outdated emote
Dark, is rtp working yet?
man idk what i'm supposed to do with that method lmao
is it out of proportion
it's too tall
i've heard that before
no you havent
might need to actually be 64x64 to make it align correctly
no i havent 
Why you gotta do me like that Z
pretty fucking cancerous
stupid? yes
How long does it usually take for premium resources to be approved
Would work? also yes
unicode is amazing
I should probably post plotsquared soonish lel
just some random guy who got into a big pedantic argument with some people about whether linux has threads or not
does linux have threads
I mean, it clearly has analog

idk if they're technically pedantically threads, I'd have to do some C shit and look at the kernel abi
no one wants that
C bad
they're called pthreads
there you go
no idea if that guy had any idea what he was talking about
but he took it very seriously
told people to go look

yeah tbh that's the dumb lore story about losing an eye
walking into a door is a better story tbh
leaf can u walk into a door
may you please walk into a door until you cease consciousness
no that'd be retarded
ur retarded because u did it

yay, ps has been papified
cringe
city you know i haven't seen you so happy in a long time
you should code more clearly

is that good for our well being tho
so i should be paid less cuz i work more? What logic is this
tbh this has sorta made me less depressed lmao
which is weird because plotsquared has the opposite effect on most people
now imagine actually working with p2
what smartness?
it's prolly your fat belly blinding him
oy, dont insult my belly
I will insult your belly whenever I want
belly abuse!
why the fuck would you return a pair of a boolean and an int if you can just return the int and check somewhere else
^^
especially since this causes stupid boxing
yes boxes are stupid
wtf is that
it returns a boolean and a count
and the boolean is just false if its 0?
so why not just return the count?

cuz he's retarded
overthinking it :p
z literally unable to read 2 messages above
we've covered this already
pliz don't randomly paste code with the comment "if someone wants to cringe"
send code if you genuinly want tips or have something actually awesome to tell
just makes me think of devon
bruh what, so he's going to give me shitty pay to then sell the plugin I MADE on mcmarket 

But if they're apparently able to implement customers suggestions themselves, then, why do they pay others to do it for them...?
good lord the more I look at that paste the more I sit here and wtf
cant do this to myself
closes tab
what in the fuck is that
deletes my browser
he's got no class 
lol
WTF IS k FOR
usually to make words
you apparently not
reee
why is the method final
steal the cake while they're distracted
yea z was right, time to close
Are plugin updates for premium resources also manually verified on spigot, or just the initial upload?
just initial

what a system 
time to release a good plugin then swap it out for a shitty clear chat
cuz that'll make a good minecrafter
dev.bukkit.org 'checks' all files
Are there any existing open-source Paper web api's you guys can share?
Some sort of REST API which can interact with the server get stats execute commands etc..
there was an older plugin that did that but I think it was broken
Doesn't have to be a plugin.
I saw a newer post about someone writing a similar plugin in r/admincraft but now I cant find it
if you want server stats it will have to be some sort of plugin involved
even if it just exposes itself over rcon
I just want to see how I can connect to it so I can write my own. Preferably not in Java since I've never used it though.
without touching java you're limited to just interacting with the server over rcon
Gotcha, maybe I could make an API to just interact with the database -> to get leaderboards and so on.
And some basic stats via rcon - online time, online players etc.
if you find some plugin that does that lifting for you and exposes that information via json or some other restful system, that may also give you more than rcon while still letting you avoid touching java directly yourself
I just cannot find that post
Going to dig a bit deeper myself as well. Hopefully there's something along these lines still maintained.

I know its new so Im not sure how extensive it is yet
there's a GH link in there that may be more up to date
I just stumbled on that a couple min. before u sent it.
Looks ~3 years old 6 months ago last update. But it does even more than what I need it for.
So should be good I'll defo. try it out.
Thanks @upper flicker
the one I linked has a commit in the last 7 days so idk if its quite the same
I know there was an older one that was more extensive, that might be what you found
not sure if it works on newer versions of the game but always worth a try
ahh that's true, I'm looking at another one, sorry
I need something a lot more minimal than the one I found https://github.com/Valandur/Web-API
Thanks @upper flicker
not being able to do shit because it freezes every time you edit files is very lit
eeermmmmmm
that ServerTap
smells unsafe as fuck
as this is very likely not executed on a main stream, no?
why unsafe
getonlineplayers is explicitly safe, all the attribute gets there may be stale but shouldn't error?
i think even if the player disconnects while those are happening the player is still intact, just the connection isn't (which none of those use)
oh wait, get address might
I just set it up
just contradicted myself cuz i didn't read fully
seems to work well, but he's mentioned it's not ready for use yet so I'm assuming a lot will be updated
(or it will never be touched again)

If you want to code, below may help: getServer().getOnlinePlayers();. OR Bukkit."
.jd
getonlineplayers is pretty much the only method in the bukkit api that explicitly talks about thread safety
the jd is kinda confusing but if you look at the impl it returns a COWArraylist
Any use of this collection from asynchronous threads is unsafe.
ah hm
fair
BUT STILL MUH IMPL DETAIL
that's illegal
:^)
Normal and immediate iterator use without consequences that affect the collection are fully supported
so yea the only issue i can see with the code above is that if the player DCs while iterating, player.getAddress().x might error somehow
unsure if the connection is nulled or broken or what but, potential issue there

sure, with some practice
but we call them jejemons
but it gets worse
much worse
let's see...
"Kamusta ka?" is "How are you?" in Tagalog.
But in Jejemon Tagalog: "mUsZtAhKa"
hf :)
it's actually reached creole language status
which is terrible
jejemoms
Lol :P
it is inspired by pokemon afaik
to be clear
they don't call themselves jejemons
people who don't like them do
these are people that speak "Jejenese", so we say they are "Jeje" - "mons"...
Jeje monsters
😂
Lol
and yes unfortunately, jejenese is now an official ISO recognized language :/
creole :/

i just use CLI.
i have used IJ's to roll back some local file changes but not to push or commit or anything.
I always do that via CLI
o, didn't know that you could stage specific lines, etc
am kinda glad I didn't know that, somehow I feel that would cause some headaches for myself
makes a commit for each line in diff
makes it very easy to end up in a state where the commit is missing changes or has other unrelated changes in it

Ha
PHP books suck, outdated and honestly trash.
honest answer, the php docs. just read them cover to cover.
Both answers were honest
Partially.
php is really easy :/ the 'hard' part, if you call it that, is it's random as FUCK globally namespaced functions that you have to learn
so yes, php docs
lots of alcohol
Tears of PowerShell.
i actually knew a guy who said linux was hard but there he was typing fucking powershell commandlets
like nobody's business
Years of scouting StackOverflow I bet.
he walked in the office every day like that
At some point you start memorizing.
1/2 the time, you have no clue what the fuck you're doing.
And you're amazed it works
i'd ask him for something every now and then and he'd be like "o yea i wrote a 6000 line powershell script for that last year let me find it in the network drive"
i think i actually screamed
i miss that guy
I need that type of dedication in my life tbh
he was married actually
we're talking about windows sysadmins are we not
Yes we are, but on the same topic of complexity
he was a married windows sysadmin, not a dev
I know.
Yes.
I'll try haha.
id first start by questioning your sanity
as to why exactly you desire to learn php
secure a therapist early for your inevitable mental breakdown
and start drinking a lot of coffee, until you get heart palpitations
Alcohol is cheaper than therapy
then you will be a php dev
so i just found out you still drown even with your face above water when you're swimming lol
thank god minecraft is so realistic
imagine if you could swim without drowning
even the inventor of php said in one of his talks that he wondered why people used it, he only made it for himself at first and waited for a real solution then everyone started using it so he kept maintaining it and now it's just the monstrosity we know today
its a lot better than it used to be
PHP is a language that really shouldn't be used for backend, but since there is no alternative everyone just kinda stuck with it
here we go again with the php hate lul
wdym no alternative
any language can be used in backend my boy
i use java
php is better now, ill agree dark
im talking early days
Sure, you can, but PHP is fucking fassstt
its faster than you for sure 🙂

Hey- does anyone know why my pex prefixes dont show up?
depends on what chat plugin you are using
I'm not- lol
Is there a better plugin for permissions, essentials and prefixes?
luckperms
Luckperms
no
luckperms does perms.
it lets you set a prefix, but you still need a chat plugin
such as deluxechat
then placeholderapi to do prefixes in the chat plugin
and essentialsx for essentials
that's the pretty standard setup
hm. Can't find deluxechat- does essentialschat work?
any chat plugin that supports placeholder api will work
essentialschat is ANCIENT
do not use that
my lord
haven't heard that shit in forever
https://www.spigotmc.org/resources/deluxechat.1277/
deluxechat is right there, it's $7.50 though.
im sure there are free ones
look for placeholderapi (abbreviated papi) support
does essentials have a chat module...?
years ago wiz
Essentialsx?
it's fucking ANCIENT
but it still works
also prefix/suffixes aren't papi related
reeeeeeee
and yea, EssX chat works fine
what have you done
luckperms prefixes can be retrieved with papi
change it back
thats why i brought it up
yes, but they are also just natively supported through vault
oh well, nice
why would you need a placeholder api if you have a chat api already

given this problem
If a ball is thrown into the air with a velocity of 33 ft/s, its height (in feet) after t seconds is given by
y = 33t − 16t^2. Find the velocity whent = 1.
i just used the former formula and it worked
but they wanted me to use the latter
what's x and a in that case? :/
what's x in the first formula
getX() done
using the first formula:
33(x+h) - 16(x+h)^2 - (33x - 16x^2)
33x + 33h - 16(x^2+2xh+h^2) - 33x + 16x^2
cancel out 33x
33h - 16x^2 + 32xh + 16h^2 + 16x^2
cancel out 16x^2
33h - 32xh + 16h^2
factor out h
h(33 - 32x + 16h)
cancel h (its all divided by h)
33-32x+16h
plug in h (approaching 0 so remove)
33-32x is the derivative of 33x-16x^2
but what do i do with the 2nd formula :/
it burnsss
i need leaf
f from x and f from a ?
velocity is the rate of change of the height, so if you derivate y, you get v
why do you need lim for that?
that formula can be used to find the derivative
yeah but how do i use it. i know the 1st one
but they expected me to use the other one
the other wat
lim h->0 (f(x+h)+f(x))/hto take a derivative but i don't really understandlim x->a (f(x)-f(a))/x-awhich should be the same thing...
ohhhh, that formula is just a way to define what a derivative is, reading it helps I guess
ye they're basically the same thing
a number
like how do i plug that in
a is the point you're interested in
do i just do the same thing
take the limit
like if the equation im derivating is y = 33t-16t^2
then, for lim x->a (f(x)-f(a))/x-a do i just 33(x)-16(x)^2-33(a)-16(a)^2/x-a
like i do for the x+h variant
cuz if so i dont see how i will end up cancelling
give me 10 seconds and i'll help you
you set a to the point you want to get the derivative of
so for this problem
If a ball is thrown into the air with a velocity of 33 ft/s, its height (in feet) after t seconds is given by y = 33t − 16t2. Find the velocity when t = 1.
then a is 1?
ye
and i just leave x in there
and i should get the same result as if i used the other derivative formula
yes
ok
I was fine with math until they introduced letters
yeah idk i didnt get the same answer lmfao
what'd you get
could it be +17 instead?
i already know the derivative using the other formula
it is 33-32x
i should get the same exact thing with this formula
ok so
i've gotten here
(33x-16x^2-(33(1)-16(1)^2)/x-1 when plugging in 1 for a... which literally just becomes (-16x^2+33x-17)/(x-1) top factors to -(x-1)(16x-17) cancel denom you get -16x+17
and yea trig was right, +17
but that's still not the same is it
what the fuck it is
im so fucking done with math
I am starting to really like the worldedit API 😛

well too many forks out there

@ please
@please
so, i finally tried the coca cola energy drink and have formed a solid opinion about it
e n e r g y
to me, it tastes like someone put big chew bubblegum in a coke and let it sit for a few days, then strained the liquid out into a can
not good

Yea, I tried one, it was pretty eh
original coke is where its at
