eternal oxide
eager turtle
okay i think i solved my issue. for whatever reason canceling EntityExplodeEvent does the mobs from taking damage
so i just set a dumby NPC i have on my server to be the cause of the explosion
then in EntityDamageByEntityEvent i check if its that entity and cancel
eternal oxide
you could just set a flag on teh exploding entity itself
eager turtle
problem is, that NPC might despawn if i go to a diff world
eternal oxide
?PDC
eager turtle
you could just set a flag on teh exploding entity itself
oh yes i didnt explain that part
eternal oxide
wake up CafeBabe
pseudo hazel
?pdc
pseudo hazel
case sensitive
eternal oxide
lol case sensitive
eager turtle
for most cases that would work, but i have a very specific case where the player themself causes the explosion. they jump in the air and when they land it creates an explosion
eternal oxide
doesn;t matter
the explosion you spawn IS an entity
you set a flag on IT not on the cause
eager turtle
yes but i need to set the source entity
eternal oxide
for blame yes, but not for the damage logic you wan tto apply
spice burrow
hmmm this works sort of. it's the effect i was looking for but unfortunately like you said at range it becomes inaccurate because the players location stays static
i think i may essentially do this exact same thing just using packets and adding the item manually
eager turtle
for blame yes, but not for the damage logic you wan tto apply
im pretty sure its the same entity used for e.getDamage() i just checked it
pseudo hazel
well yes, but if its not loaded, how does it take damage
or am i misunderstanding
but it shouldnt really matter
all info you need can be saved in the explosion
then it doesnt matter who done it
eternal oxide
teh getEntity in teh EntityExplodeEvent will always return the exploding Entity
set a pdc flag on that when you create it
detect it in teh explode event
the source you set will be available in the damage event
eager turtle
heres the whole thing. a trident can be thrown and cause an explosion. a throwing tnt can be thrown and cause an explosion using createExplosion and passing in the trident and tnt entity as the damage sources. I have metadata attached to those two entities so i can ignore the damage in EntityDamageByEntityEvent and apply my own damage. I do this because these weapons can be upgraded and I want to increase or decrease damage. The problem is the player themself can cause the explosion by jumping in the air and landing. So if i set the player as the damage source entity then i run into issues. Because I can check if the damaging cause is an explosion then check if its the trident or tnt with my meta data were the damaging entities and cancel. But if I do damage cause Explosion and get the damager and its a player, well i dont think i can cancel that because a player setting off TNT normally in survival would be linked to the damager and i dont want to also cancel that. but maybe the damager would be the TNT that was set off
eager turtle
set a pdc flag on that when you create it
this could work but with a special metadata instead since its temporary
at least better than using my dumby npc
now that i think about it more, does a player setting off a standard TNT in survival and it killing someone even count as their kill? should it
eternal oxide
normally no
eager turtle
i guess i gotta test it
if they throw a fireball they wouldnt normally be the damaging entity either i assume
i guess that could maybe work
eternal oxide
Normally no, as thats not vanilla mechanics
you can via teh API though by setting the source
eager turtle
ah okay, well id probably just use metadata on the fireball to circumvent that anyways
eternal oxide
Note setting teh source is setting the damage source not the explosion source
eager turtle
so as it stands i will do damageCause = explosion, then check if its my trident, tnt, or player. Then cancel
eternal oxide
with thrown fireballs, it's usually a launched projection so it has a shooter
eager turtle
damn yeah
but a projectile right? or still explosion i guess if its not a direct hit
regardless, in EntityDamageByEntityEvent the damager() would still just be the fireball
it should never be the player if its an explosion
eternal oxide
with launch you use a disguised projectile, then cause the explosion on hit
chrome beacon
If the trident is what explodes then it would make more sense to put that as the entity
also it's preferable that you send text as text

Hi, how can I change the size of the armorstand (the hitbox)
chrome beacon
For what purpose are you trying to change it
eager turtle
If the trident is what explodes then it would make more sense to put that as the...
yes
but the player themself can do a special move where they jump in the air and land on ground causing an explosion
dusty nexus
For what purpose are you trying to change it
Is it possible ?
eager turtle
so if i pass them in ill be checking for the player anyways with that part. so i just set the player as the damager for all types
eternal oxide
Is it possible ?
depends on how you want to change it
dusty nexus
Just the hitbox
chrome beacon
Is it possible ?
You can change it on the server, not the client
eternal oxide
change how? Bigger, smaller?
dusty nexus
smaller
eager turtle
as far as im concerned there will never be a case where theres an explosion and the player is the direct damager entity. except for where i explicity say to in my code
so i cancel that
and it works great now

can u show me?
eager turtle
If you really wanted to use an armor stand without a hitbox, then your answer is nms (sending packets)
grim hound
You'd need to override the internal hitbox (probably each time it's refreshed)
eager turtle
I think using the scoreboard you can at least get one under
grim hound
And send refresh hitbox packets (dunno what that is)
dusty nexus
I think using the scoreboard you can at least get one under
Nah player's name can't be with hex colors
Thats why I'm trying this way
eager turtle
Yeah i think you gotta go with nms, unless you can attach a TextDisplay to a player
But i dont think those are entities they cant be mounted you would have to update the location basically on playermovement which can be slow to do for every player
TextDisplays are 1.20.6
Havent used them yet they might be easily attached to an entity dunno
dusty nexus
The addPassenger is smooth asf and I need a same result to place the armorstand above the player
eager turtle
And now that i think about it, with nms youd still have to teleport the armor stand to the players head on movement probably
pseudo hazel
arent text displays 1.19.4 or whatever?

dusty nexus
lm see
blazing ocean
you might have issues with teleportation, not sure how spigot handles that, paper doesn't directly allow you to without a flag that's all i know
eager turtle
True if its a passenger. But he said he wants to use passenger anyways
So hes prob accounting for that or should at least
blazing ocean
spigot doesn't have that flag but it should tp i think
cross-world might not
blazing ocean
What about on death?
unmount and then mount on respawn
blazing ocean
Does it stay as passenger
nope

it looks really bad too

So @dusty nexus think of these edge cases when you do passenger

eager turtle

Ye
dusty nexus
ye
blazing ocean
the nice thing is that you can just do Player#hideEntity
oh also gamemode switching!!
important
eager turtle
My server never got big enough to notice a delay i just read to never use playermovement if theres another way
I have one check for it and its to raise the void height
Actually wait
I changed it to a runnable
blazing ocean
I changed it to a runnable
every tick tp it??
eager turtle
Every tick i check their Z value and if its like below 40 i kill them
blazing ocean
Every tick i check their Z value and if its like below 40 i kill them
okay but that's unimportant here and pretty sure you mean y
eager turtle
Cause i made a skylands map and dont want to put the islands close to the void and have it look all shitty and dark
Yeah i was just saying i avoid playermovent at all costs if theres a better way
And right now text display as passenger is the way
blazing ocean
I changed it to a runnable
i still do it with the move event tho
eager turtle
I mean if it works it works
blazing ocean
I mean if it works it works
should be better than a task
as it doesn't check every tick
blazing ocean
Its not every tick i do every 10 or so
pretty sure playermoveevent triggers at least every 4 ticks
eager turtle
Probably more actually like 20
blazing ocean
as it's 5x/second if not moving
blazing ocean
Yeah and at most how many?
wdym? every tick ig
eager turtle
Yeah
blazing ocean
only if the player is moving
eager turtle
It could maybe send an event multiple times per tick
If they are sporadically moving
blazing ocean
It could maybe send an event multiple times per tick
nope
eager turtle
At least for my case its not necessary
Ah okay i dont really know what constitutes as an event for that
pliant topaz
This might not be an ideal solution for my problem (certainly a bad solution xd) but it's been the only thing preventing me from finishing for around a month now, and it's really unmotivating i gotta say, so I've come up with another solution.
As the data needed to be stored isn't much, it's possible to store it in localizedName. Ik this is a bad thing to do, but as I already have ways of identifying items which would use that, I could grab the real localizedName, as I would seperate the data with another character I won't use otherwise. The data could then be split by, for example double underscores so I get all seperate pieces of data.
The actual problem I had with PD I'll leave for future me to solve, maybe when I'm more experienced with PDCs as this was the first real time working with them
blazing ocean
Ah okay i dont really know what constitutes as an event for that
check out ServerGamePacketListenerImpl
eager turtle
Huh insteresting never seen this. And now that i think about it more itd be impossible to send an event multiple times per tick that doesnt even make sense logically. Im tired lol
Well basically i use runnable cause i only need to check every 1-2 seconds. For something more involved like a second nametage obviously playermovent is the best itll get
But of course we got text displays now
So add that thing as a passenger and go wild
eager turtle
This might not be an ideal solution for my problem (certainly a bad solution xd)...
What are you trying to do exactly. Give a broad overview of the start and end goal
Often the solution you are already implementing could be flawed and there might be a better way to do it overall
So if you just give a general statement with some examples of edgecases im sure we can come up with a solution here
pliant topaz
So I basically have 'Tool' items which can have up to 3 upgrades and theoretically unlimited abilities. Upgrades and abilities are stored in enums, which hold all the data (identifying name). These names get converted to integers acccording to what value I gave them, and from that I store it in an integer array for storing in PDC
My end goal is that this works flawlessly and would work for every item
But somehow even when I overwrite this data, It still shows the already modified one, which is from a different item
lmk if u need any other information (I'll be away now bc RL's calling lmao)
important code pieces are found in replies from the messages if u go through the replys
eager turtle
Heres an idea for what I think you are trying to do. You want special items on your server? Create a java class called Weapon and use that to store an item and any special attributes about it such as material, damage amount, name, methods that do special abilities, upgrade values in arrays, etc. Then create an Enum class which will store the WeaponType, like THORS_HAMMER for example. Add this enum as another field inside of your Weapon class. Now when you want to give a player a special item, you simply create an insance of your Weapon class (which will create the item) and then give that item to the player. When you create the actual item inside of the Weapon class, attach a PDC to it that stores the WeaponType Enum you made earlier. Then whenever a player uses that item such as for a BlockBreakEvent, you can do item=e.getItemInMainHand() or whatever it is and then simply retrieve the PDC from that item. Then you get the WeaponType from the PDC you stored earlier. And now you know the exact Weapon they are using. Keep in mind you will only know the type at this point. But if you are being a smart programmer and storing your Weapon instance you made earlier to give to the player, you can simply say okay I know hes using THORS_HAMMER so im going to go retrive that Weapon instance I made earlier so I can get values from it I need.
I just read your last messages what i wrote should apply
You are going at it like a caveman, you need to use a wrapper like i suggested. The Weapon class will be your wrapper
If you need any help with direct implementation @ me

So I want to send data from lets say KitPvP to Hub
Using Bungeecord? I think theres a Bukkit Plugin Messaging Channel
quiet ice
the other alternative is that you consider the ips to be static and do a direct plain old TCP/UDP connection which is negotiated using a plugin message or via the configurations - but that isn't ideal compared to more stable solutions and also means that TCP/UDP port needs to be exposed in the first place

You could put something in their left hand

You could also just place an entity in front of them so they interact with that

The client know a lot of stuff. That's what hackers do. They use data that the client would normally not display and kinda adds an "overlay" over your screen to show you some secrets

in the early days u could even modify ur own inventory while in survival, thank god they made it serverside
zealous osprey
Because it's very hard to know exactly what the client should and shouldn't have. Most of the reasons also just boil down to make the server run more efficiently and not let players, blocks and entities in general appear out of thin air

yesn't.
Let's view the following example:
Two players are sperated by a stone wall, neither of the players can see each other. With your logic, the server shouldn't send the players any data about the other player. Well... that makes sense, but there are two issues:
- The server would need to do multiple checks to make sure that players that should be able to see each other actually do so. This issue gets worse the more players you have. 2 players is fine, the server checks if Player A can see Player B and Player B checks if they can see Player A. But you rarely are only 2 players. Now lets assume you are something like 16 players. That would be 16 checks per Player for a total of 256 checks. Depending how this check is performed, this might take a while.
- Player A walks a bit to the side, so far that Player B should be able to see them. Since the server will most likely check every tick if players can see each other, it'll take at worst 50ms before the server checks if the players can see each other. But don't forget that it will also take some time for the data to be sent to both players, maybe 20ms. At thins point a grand total of 70+ms have passed before players could see each other. On your screen it would seem like the player just appeared out of thin air. That's... shit.
Reasons like these just make it impractical to sanitize every bit of information that gets send to every client. It's far easier to just estimate that every player within X blocks should be informed about the player. Then the client does the calculations, therefore a lot of load is removed from the server.
zealous osprey
so latency > hackers
hackers can use latency to their advantage. There was an issue where hackers just didn't send movement packets to the server for a while and then spammed a bunch when they wanted to "teleport". Since the server was naive and trusted the players, it execute the "movements" one after another, effectively teleporting them to a destination.
I think paper and spigot might still have this issue, but in a very, very small amount. While you can't "teleport", you can move a very small amount, iirc
quaint mantle
Any thoughts what this kick means?
https://imgur.com/a/crash-RTrg2wc
zealous osprey
with the "moved too quickly" thingi
yeah, but there's also the opposite. If you sit in a minecart and still send movement packets, you get moved a very tiny amount. So you could just ride a minecart without tracks. This was once used to ignore protection rules for some protection plugins

omg im triggered, I am trying to use the translated texts for statistics for minigame purposes, but for some reason, while all other languages have 2 arguments for the player killed "entity" "2" times, some languages like french and spanish only have one argument
cuz the translator was lazy or something
so it doesnt read well since the actual mob you killed isnt in the translation in that case
but its only for about 13 json files
all the other languages have double arguments, like you would expect..
fair rock
Sure he was lazy? Not he was like: Do it on purpose to fuck someone up, that would be hilarious xd

yeah well they did it I guess
it is kinda funny
but its also kind of an unsolvable problem for me

True, sadge

I can cheese it a bit
it would just be You killed 2 " " (mob_name) which works for most languages, where " " is an empty placeholder and (mob_name) is after the translated part
works well enoug I guess

Anyone know an event for when primed TNT explodes, affecting (usually moving) other primed TNT?
I checked EntityDamageByEntityEvent, but it isn't called since the primed TNT doesn't deal damage to other primed TNT. I can't find anything else in the Spigot javadocs that may be fired in this situation.
Currently my solution is to check nearby entities for primed TNT on EntityExplodeEvent and manage them that way. But I'm wondering if there's a better way. If not, that's chill
young knoll
Does it call EntityKnockbackEvent
carmine mica
is TNTPrimeEvent not called?
young knoll
Should be, but that’s basically the same as the explode event
Just allows you to stop the explosion from happening

Not for my situation. I'm looking for when primed TNT affects other primed TNT rather than priming blocks

you're not shading it
show your pom.xml
drowsy helm
What java are people using to compile for latest mc plugins? 21?
17-21
wooden thicket
drowsy helm
yeah it's not being shaded
so basically during runtime, the library isnt available. Shading it puts the needed library (in your case postgres) inside your jar so it can use it
young knoll
Yes
drowsy helm
if it's not in the spigot runtime, yes
but there is an alternative with spigot
sec
fluid cypress
what is the easiest way to serialize an item stack into json? im using kotlinx.serialization btw
drowsy helm
look at the libraries section
basically spigot will load your library at runtime, rather than it being shaded in your jar

unless theres a lib out there, you will have to manually do it with an adapter
drowsy helm
is this the section
yes
wooden thicket
would it just go inside the pom file
drowsy helm
no thats inside your plugin.yml
if you don't want to shade it
If you do want to go the shading option, look into maven shade plugin
drowsy helm
for such a large lib like postgres i would use the plugin.yml alternative as it might be shared by other plugins
fluid cypress
unless theres a lib out there, you will have to manually do it with an adapter
there has to be

there has to be
does it have to be human readable?
fluid cypress
if not, at least, if i want to be able to not lose any information, what do i have to serialize? material, amount, enchantments, lore, idk what else
fluid cypress

no

I got one of those
drowsy helm
i just dont want to do it myself
can serialise to b64 or a binary blob
fluid cypress
i mean, unless i can convert Map<String, Object> to a json string somehow
fluid cypress
can serialise to b64 or a binary blob
what i want is to store it as json in a database, and then access it from javascript, and be able to get its name, enchantments, all of that
so it doesnt have to be readable
but it has to be json
drowsy helm
i mean you can still serialise it but it wouldnt be ideal
just make an adapter and manually store the variables, theres not that many
NBT, name, desc, stack size, material
thats about it
fluid cypress
for example if i do itemStack.toString(), its almost like what i want, just that its not json, its some other weird format
drowsy helm
are you using SQL or a no sql db
because if you use an ORM on your javascript side it will automatically get converted to json
fluid cypress
sql
drowsy helm
storing it as json in the db is just adding an extra layer of complexity
fluid cypress
because if you use an ORM on your javascript side it will automatically get conv...
not sure what you mean
you mean using ItemStack#serialize
and storing it as blob
and then an orm will magically convert it back to json?
drowsy helm
no
store it in a table as you would any other sql object
{
name: varcar(256),
desc: varchar(256),
etc..
}
fluid cypress
right
drowsy helm
then your ORM on the javascript side will convert it to json
drowsy helm
why..?
fluid cypress
so i dont forget stuff
drowsy helm
you're using a proprietary method to consume the data, expect there to be some manual work to get it working
fluid cypress
and bc i plan to use items adder and idk how does all that work
young knoll
Probably all in pdc
fluid cypress
you're using a proprietary method to consume the data, expect there to be some m...
but i mean, there is already a serialize method provided by spigot so, i dont know why it cant be json
drowsy helm
itemsadder doesnt add ontop of anything that spigot doesnt use
fluid cypress
you can even store that directly in a yaml iirc
drowsy helm
if oyu cover everything spigot does, it will work with items adder
fluid cypress
Probably all in pdc
i dont even know what that is
young knoll
Spigot has methods to convert it to yml
fluid cypress
and thats why i wanted to use an already existing serializer and not my own
young knoll
Which is a subset of json iirc
fluid cypress
Spigot has methods to convert it to yml
really?
young knoll
Yes
fluid cypress
which one exactly, i guess i can serialize it to yaml and then json
young knoll
ItemStack#serialize converts it to a map<string, object>
From there that gets converted to yml
drowsy helm
map it to a json object
young knoll
Various types
drowsy helm
can be anything
young knoll
Should be all primitives in this case though
and collections of primitives
(And string which technically isnt a primitive)
fluid cypress
ok but how do i create a string in yaml format from the Map<String, Object>
how does spigot do it
iirc you can do config.set("something", x)
drowsy helm
string is just the item path
fluid cypress
x being the Map<String, Object> serialized thing
drowsy helm
x is just the value which is always a primitive
all it does is iterate over the map and put the value where the path is
young knoll
Yeah you can stick the entire map into spigots yaml objects
It handles the rest from there
fluid cypress
ok, good to know, but how do i use that information to create a yaml string
fluid cypress
It handles the rest from there
yea, thats what i mean, how does it handle it
is there an easy way to go from those paths with their primitives
to a yaml string
drowsy helm
past that point, is where it uses snakeyaml
String.valueOf(x)
if its a primitive, valueOf will work
young knoll
You should be able to just String.valueOf anything that isn’t a collection or another map
fluid cypress
ok so the snakeyaml library is what can convert a Map<String, Object> into a yaml string?
young knoll
Yes
Gson might be able to deal with that map too actually
Assuming the meta in that map is already serialized, it should be all types gson is able to handle natively
wooden thicket
is this what you ment by shaded?
drowsy helm
is this what you ment by shaded?
have you decided whether you are going to shade it or use the plugin.yml
wooden thicket
have you decided whether you are going to shade it or use the plugin.yml
I'll use the plugin.yml
which was already provided to me
with mavern
drowsy helm
okay add
libraries:
- com.squareup.okhttp3:okhttp:4.9.0```
but with the lib you needin your plugin.yml
wooden thicket
plugin.yml is spigot, not maven
my apologies
I used a mavern plugin
to create it
it generated it
is what I meant
name: easylogin
main: com.pixelite.easylogin.Plugin
version: 0.0.1
api-version: 1.15
author: ("Rose")
commands:
register:
description: Creates an account

do I got red of the "-"
wooden thicket
okay thank you
I am not sure what I need though
I cannot find any tutorials on youtube
nor does it mention it
in the series
drowsy helm
the postgres library
wooden thicket
I've been following
drowsy helm
that you import in maven
drowsy helm
nor does it mention it
mention what
wooden thicket
mention what
libraries
wooden thicket
yes
well the tutorial I followed just assumed the watcher
already had it
and didn't provide any context
¯_(ツ)_/¯
i did find this though :p

Assuming the meta in that map is already serialized, it should be all types gson...
yea, Gson().toJson(itemStack.serialize()) works exactly like what i want, thanks

Read docs https://jd.papermc.io/paper/1.20.6/org/bukkit/block/Block.html#getDrops(). It’s not the drops that will drop from the block
It’s just potential drops as if it ran the loot table once.

Well spigots javadocs aren’t helpful for that method

In IntelliJ there is a feature where when there's a color in the name of something (like a class or method) it will show that color on the side of the line. Anyone know of a vscode extension that does something simmilar to this?
I'm remembering to when I used IntelliJ and it would show a color preview whenever I would use a Bukkit Color or something like that

that might of been from the minecraft development plugin on intellij? dunno if that adds it
not sure if someone made it for vsc
