@south shoal you haven't imported anything

@south shoal It's not an error, it's a warning cause you're launching a task useless (TIP: hover the message to see the errors etc)
south shoal
I have used ctr + shift + o more than once (using eclipse)
sturdy oar
Also I quickly looked at your code
silk bane
it's a bit of an error because none of the symbols are defined because he has one import
sturdy oar
you're missing override annotations

@silk bane This is imported nah?
sturdy oar
@undone narwhal forr PVP and around 50 plugins and 200 players
@pastel igloo ?
silk bane
what is?
south shoal
So what do I need to do?
silk bane
oh maybe class names are just highlighted red
undone narwhal
@pastel igloo You can then use a fork that remove entities mechanics or reduce it. Paper is really enough but I don't really know the others, have to take a look
silk bane
interesting design choice
undone narwhal
Yep konsolas, if the class weren't imported, the methods would be red
sturdy oar
Paper can probably handle 200 players with proper optimization.
Note that this doesn't mean to just throw in aikar's flags and set every value in the configs to low expecting to automatically get 20.00tps 24/7
undone narwhal
or underline
silk bane
the whole thing would probably be red
undone narwhal
Paper and configure it to remove entity mechanics and other uneeded stuff (hoopers, etc)
sturdy oar
I mean if he told it's a pvp server there will actually not be a lot of entities
which helps the server a lot
undone narwhal
For sure
But in my case I prefer disabling entities in that kind of server, then the server will (I hope) totally not calculating for entity spawning or other stuff

is it better ro ask development questions here or on a forum thread?

yes

yeah I want to call Server.Spigot.restart() but get a compiler error "Error:(54, 26) java: non-static method restart() cannot be referenced from a static context" Although Server.Spigot is static and my context is non-static... which is extremely confusing
undone narwhal
restart method is part of a Spigot instance, so you can't call it statically
shut ember
ah, thank you so much
I was utterly confused, because it didn't even seemed to be right calling the class directly
also I would like to use the same CommandExecutor for two different commands
but it does not work as I intended
public void onEnable() {
Commands cmds = new Commands();
this.getCommand("one").setExecutor(cmds);
this.getCommand("two").setExecutor(cmds);
}
you can't ?
you'll need to register aliases in the plugin.yml
or make two separate classes
shut ember
oh okay, thats news to me, thank you!
sturdy oar
pro tip
i don't want to advertise this every 5 seconds but...
ACF library is real good for managing commands
shut ember
found the corresponding wiki page
I don't think I'd have any use for ACF atm, but I made a note to use it later on, if the project grows
sturdy oar
well i was kinda forced to use it
the onCommand method simply was getting too complex without it
south shoal
so how can I update a scoreboard every sec
sturdy oar
you use a BukkitScheduler that runs every 20 ticks
south shoal
and how would that look?
sturdy oar
plugin.getServer().getScheduler().runTaskTimer(plugin, () -> {
//your task here
}, 1L, 20L)
so a //Your task here needs to ve a void
south shoal
so put that in the void onEnable
sturdy oar
i have no idea what are you trying to achieve 🤷♂️
that is just how to do a repeated task
south shoal
hahah me iether
sturdy oar
🤦
keen compass
@shut ember you can use subcommands if you only want 1 command class
shut ember
how though? @keen compass
keen compass
give me a sec to show you an example
sturdy oar
yeah i hope you're not going to have a different command for each subcommand
you basically have to work with the args passed by onCommand
sturdy oar
or use ACF 🧠
keen compass
don't have to exactly do it that way, it is just an example in how it can be done
shut ember
Subcommand like
/command subcommand
/command subcommand2
balmy sorrel
Hey, do you know any idea how to add a list of bans in a plugin?
sturdy oar
what does that mean
shut ember
because I mean like
/command1 arg1 arg2
/command2 arg1 arg2
sturdy oar
you can do subcommands by checking the array of strings passed by onCommand
shut ember
that's what I am doing
sturdy oar
gg
keen compass
well the classes I linked to do exactly that
shut ember
I have two commands with the same syntax but different outcomes. They are bonded because they trigger a scheduler of which only one can exist at a time, so I assume I have to work with the aliases. Or how else would I be able to find out if the scheduler is already running?
keen compass
only thing is, they are separated into their own class to make it easier to tell which is which
instead of them all being in the same class
south shoal
oke explanation about my code
RED > Scoreboard on the right of your screen
GREEN > Luckperms prefix gethering
BLUE > eco gethering
ORANGE > Date and time gethering
keen compass
@shut ember assign the scheduler to an int to get its id
this way you can always check to see if the scheduler is running
south shoal
and how can I make it that the time eco and rank get a update very sec
south shoal
hhaha ok
keen compass
put the date and time in its own thread and then access it when you need it @south shoal
shut ember
i can assign the scheduler to a var when using the same class for issuing both commands (what I am currently doing)
but how can I callthe id from another object (?)
@sturdy oar I can help you with SQL if you like
keen compass
make the ID available to the class via a method
sturdy oar
i'd like that
south shoal
The time and date need to shown all the time
sturdy oar
but it's kinda not easy stuff
shut ember
no prob, I like puzzles
sturdy oar
if you want to help i can write a full explaination on what I'm working on
keen compass
@south shoal that is fine, you can still have its own thread to be updated. Use a method in your scoreboard area to get it.
shut ember
that could help
sturdy oar
ok it'll take few mins let me write it well
keen compass
and then you could just use a runnable to get it every so often
south shoal
and how would that runabel look like?
keen compass
just like any other? o.O
south shoal
hahah
keen compass
I don't do much with scoreboards so I can't really tell you what methods to make use of really
I am not a particular fan of scoreboards
sturdy oar
I have this table which has the current rows:
player_uuid of type CHAR(36), player_name of type CHAR(16), and three rows of type integer called (flags_ipv4, flags_domains, flags_words). The uuid of the player is of course the primary key of my table and is unique. However the usernames and the flags are only not null. What my plugin does is listen for whenever one of does flags gets triggered from in game, and as soon as the flag gets triggered an sql query on the database should increase the correspondent flag on the database. This sounds pretty simple however there's this issue: if the player is online and already present in the DB, i just need to increase that specific flag by +1 , but if the player has never joined i need to add him with that flag set to 1 and initialize all of the other flags to 0 (I have access to username and UUID so that's not the issue).
I've currently only figured out how to do the part where the player is online and already present in the db
This isn't spigot related support at all , so i don't expect to get help.
keen compass
so your issue is if they are not in the DB?
sturdy oar
yeah, because i don't know how I would set every OTHER value than the flag to increase to 0
shut ember
first I would query
SELECT flags_ipv4, flags_domains,flags_words FROM tablex WHERE player_uuid='uuid'
If youz get an empty set you can initialize it
and everything else you can update pretty easily
I am not 100% sure but I think the empty set will be null
sturdy oar
my latest attempt was setting the integers as nullable, and using a null check to set them to 0 when null (indicating the player has never recieved those flags before), but I don't think that was a good idea
gleaming helm
Make sure you use a prepared statement ^^^^
keen compass
to also aide you, can use the api methods to check if the player has played before as well on the server
balmy sorrel
Does anyone know how to make a kind of list of bans ?, and with a command that list comes out?
gleaming helm
That doesn't necessarily correlate to if the user is in the database
@keen compass
sturdy oar
yeah Kevin_ im using IDB repository from Aikar so i don't have to make prepared statements, the lib does everything for me
sturdy oar
to also aide you, can use the api methods to check if the player has played before as well on the server
@keen compass lol i didn't think of that
that might actually make things much easier
i'll have two different statements
keen compass
@gleaming helm maybe not, but it makes it easier to know if an insert if exists statement should be ran though
gleaming helm
No it really doesn't
gleaming helm
You still have to check
And you can reset your player data
And not the database
and cause massive problems
keen compass
@sturdy oar should just add everyone that joins with 0 values
sturdy oar
yeah
gleaming helm
That's the dumbest thing I've ever heard when you can just check if it exists
Or even do an upsert
shut ember
to verify if the entry is present you can either do this:
https://javarevisited.blogspot.com/2016/10/how-to-check-if-resultset-is-empty-in-Java-JDBC.html
Or you count the results (which you should if you only query for one result)
https://stackoverflow.com/questions/2763659/how-do-you-access-the-value-of-an-sql-count-query-in-a-java-program
gleaming helm
Just do an upsert lmfao
balmy sorrel
Does anyone know how to make a kind of list of bans ?, and with a command that list comes out?
gleaming helm
Is your goal to either update or insert if it doesn't exist?
Use an if statement in mysql
SQL is a turing complete language
sturdy oar
well it's SQLite im using , although it's pretty much the same
gleaming helm
Still query language is SQL
Which is a turing complete language
That (as turing complete languages do) supports branching
keen compass
With some small exceptions to certain SQL things though
shut ember
@balmy sorrel what exaclty do you mean with a list of bans? Your own list? another plugins list?
keen compass
sqlite has some things not quite the same with MySQL
sturdy oar
sqlite even breaks between spigot versions to be fair
gleaming helm
The query structure is the same @keen compass
balmy sorrel
My own list @shut ember
keen compass
to an extent it is, depends on your query is done. For instance sqlite has a couple different data types that are different
keen compass
so in regards to say creating a table, the query is not the same
shut ember
@balmy sorrel I think you need a multidimensional array//list and a storage layer. ?
sturdy oar
java 32bit
gleaming helm
But it's still SQL. The query language is still the same, and the base query features are still the same. And turing completeness, which is my entire point, is definitely a base query language feature.
sturdy oar
🤦
sturdy oar
you hava java32 bit
wind dock
Damnit
sturdy oar
i bet my ass on it

Anyways, depends on how your servers are setup. I usually keep track of all players that have played regardless of the server and regardless if its a new server in the network
balmy sorrel
@shut ember I just need a command, for example / banlist to say in the chat the list of bans and the reason
sturdy oar
why the hell jdk 13 lol
keen compass
This way, I don't have to run unnecessary queries, I always know if a player should be in the DB or not. Of course there is exception checking which is where depending on what happened the DB gets fixed 😉
sturdy oar
i'll check upsert on some tutorial online
gleaming helm
And inside code different logic for if it exists or doesn't exist
No error checking necessary
keen compass
Except, depending on how many records there are, isn't always optimal to do
wind dock
whats the website to download java 8 from
sturdy oar
the thing with adding whoever joins into the database, creates the issue that the database gets massively big without a proper reason
and i want to avoid it
gleaming helm
You should be using indexes
If you're not using indexes and PKs properly
Please stop fucking using sql
keen compass
the fastest method I know of aside from just having functions already on the DB server, is using Insert Except if you have large amount of records
gleaming helm
No
You misunderstand me
You do realize
You can write an if statement
inside of a query
Correct?
shut ember
@balmy sorrel so you need a plugin or are you developing one? Sounds like the first
keen compass
Yes I know
gleaming helm
Good
So it's settled
The fastest method with the lowest query velocity
Is to write a single query to the DB
That performs a different action depending on
If the user is already in the DB or not
And if you're using indexes properly
The size of the DB doesn't matter
keen compass
Or just already know which should be ran before hand 😛
gleaming helm
And if you're not using indexes, your query length will be the same either way
How you going to know without checking the database
shut ember
which is impossible if you don't know your data beforehand ^^
wind dock
https://www.oracle.com/java/technologies/javase-jre8-downloads.html is this the website

Do I need other exploit fixer such as "CustomPayloadFixer" with this plugin https://www.spigotmc.org/resources/2ls-exploitfixer-professional-server-antiexploit.62842/ or not?
keen compass
because the servers know if a player has played before on the network the moment they join. Therefore an insert isn't required unless for some weird reason they were not added before
balmy sorrel
It is my first plugin, and I want to implement the list of bans in my plugin, and I am saying how to do it @shut ember
gleaming helm
And do some reading first
keen compass
which generally shouldn't happen but because it is a rare case I just catch the exception
and fix it from there
gleaming helm
That is such a terrible idea
gleaming helm
To any reasonable person who knows how to properly write SQL queries
Also
Just so you know
I run a relational SQL database at work with more than 1 billion rows
The average query time
keen compass
that is fine
keen compass
your solution isn't the only one
gleaming helm
SQL can handle very VERY large row counts
keen compass
never said it couldn't
gleaming helm
Assuming you're indexing properly
sturdy oar
I'll try to post my sql whenever i've finished writing it so you can tell me if i've done it right
gleaming helm
A check to see if a row exists
Is something sql does ANYWAYS when you're inserting with a unique constrained key
Which you should be doing if you're using a UUID as a PK
(Well... which you are doing, because the PK is uniquely constrained)
keen compass
But, I don't do inserts all that often unless someone is new to the network is the thing
all the queries are fetches
gleaming helm
Yeah easy, so you just fetch the row and if you get no row you assume some defaults
Don't even need to write your defaults to the DB
keen compass
I don't even do that
I don't bother fetching a row if they never played on the network
shut ember
@balmy sorrel sender.sendMessage("message");
gleaming helm
How do you know they've never played
pastel igloo
oh okey
gleaming helm
Oh right
By using some potentially ephemeral player data file
That sounds REAL robust
keen compass
My setup keeps track if a someone new connects to the network. I don't use the player data file on the servers
why access player data files when it I can have it centralized?
So before a player even gets to a server, the data for if the player has been on the network before is already available to said servers
keen compass
no
gleaming helm
Wasn't the whole point to not make database calls?
keen compass
I don't make a database call for it
keen compass
I guess the servers player data way is magic too for you
guess there is no other ways
because you can't fathom other methods XD
gleaming helm
If you don't handle a playerdata file. And you don't make a database call. How the hell do you reliably replicate the data to all nodes in the cluster? I mean... can't possibly be reliable at all
shut ember

You don't need an account

gleaming helm
Except I want to use java 11 features and I can't and it's balls
shut ember
me too
gleaming helm
You do realize that java is fully backwards compatible right?
sturdy oar
unless the plugin is real retarded
gleaming helm
If a plugin doesn't work on java 11 it's because the person who wrote it is mentally retarded
shut ember
^
keen compass
@gleaming helm symlinking a file that all servers have access to for reading is a thing first off, even if not on the same system. Second, you can use plugins on the network to communicate with each other, and only one of those really needs to keep track of the data. Essentially I just the concept of what the servers do, and just have it in a central place.
sturdy oar
If a plugin doesn't work on java 11 it's because the person who wrote it is mentally retarded
@gleaming helm some have been found
it's better to delete them lol
keen compass
Most that don't work is because of reflection
reflection changed after java 8
starting with Java 11
keen compass
It was removed
Well it isn't so much removed
but it was changed in how it was done
How it is done now in Java 11 higher respects security
sturdy oar
i think now trySetAccessible has been set as preferred over setAccessible
shut ember
I assume you guys use openjdk?
keen compass
I use oracle JDK but I do also use openjdk since the CI hates oracle JDK
sturdy oar
@shut ember I'm a proud user of GraalVM
keen compass
requires a license to use Oracle JDK unless what you are using it for isn't for commerical purposes @shut ember
shut ember
haven't been able to set it up right on windows and am too lazy to properly set up any server fpr it
@keen compass it isn't commercial

you are removing it from the list at the same time you are trying to read it

Has someone here already used Factions API?
keen compass
many people have
just don't expect welcoming comments though
as many tend to dislike it
undone narwhal
Yeah for sure
keen compass
but feel free to ask your question anyways 😛
undone narwhal
Just wanna know if there is a method or kinda custom event thrown when the player move and enter in a faction or in a warzone region etc
Or if I've to check on the playermoveevent lol
keen compass
since it uses worldguard, you can just listen for worldguard region events
undone narwhal
Really? Awesome. Didn't know that it used WG
keen compass
yep that is how it makes its regions and what not
but Worldguard throws an event when players enter and leave regions
shut ember
so I am back to my drawing board.
I tried to use the alias-key in plugin.yml, but that didn't work as intended.
my Goal:
Have two commands with the same argument interface, but doing different things:
/broadcast -time 12 -comment "hi" -asConsole
/log -time 12 -comment "hi" -asConsole
(examples)
I don't want to have messy code and fix one detail on the argument handling in multiple classes. There has to be a simple way.
keen compass
since the root command name is different
just use 2 command classes
not really an issue to register 2 commands in the onEnable()
just make a method class that both use
this way your command classes are small and just execute the same methods
shut ember
a method class 🤔
keen compass
yep, a class or even in the main class, that both call but it does the same thing but differently depending on which command was ran
just have it take in the argument of the command name
shut ember
sounds reasonable. Could input the args[] and output a results[]
keen compass
public void commonMethod(String command) {
if(command.equalsIgnoreCase("broadcast") {
//do something
} else if (command.equalsIgnoreCase("log") {
//do something else
}
}
then in your command classes, you can execute that method
so command classes stay small relatively and both share common code
without duplicating it
but its however you want to do it as well. Just an example after all 😉
could even make it a boolean method if you want to check to make sure it ran fine
alright, now I am off. Have fun everyone 😄

How are you supposed to spawn a falling block?
I have a location and a block
sturdy oar
@keen compass I think something like this should work, although i'll need to use String.format of course
gleaming helm
Yeah that's perfect
(Don't use String.format, use a prepared statement. Even though it's difficult to SQLi in this instance, it's better and faster to use a prepared statement because the database can cache the query)
(And don't think it isn't possible to SQLi this. In an exploit chain in which the user has control over your server side username, possibly through a bungeecord exploit or similar, they can insert illegal characters and execute queries on your DB.)
sturdy oar
i can't use prepared statement everywhere sadly
gleaming helm
Why not?
sturdy oar
however i am 100% the input is sanitised
gleaming helm
For that best practice is to write n separate queries to increment the fields separately
gleaming helm
Yeah make a different query for each flag you're incrementing

and do a switch over the flag i'll need to use*

hide the armor stand from that specific player
only admins get to see it
not the random passerby

you need to spawn that holograms with nms

how so?
tiny dagger
i was hoping you knew because it isn't short to explain

Is there a way to force an item to craft and add to players inventory instead of clicking on the result slot?

If a server was running version 1.13, is there a way to allow 1.14 and 1.15 clients to join? I've seen some servers where that is possible but I don't know if it can be done on spigot
undone narwhal
You can use ViaVersion plugin (but I strongly recommend you updating your server to 1.15.2 as many security and other impovements are made, don't bring back the version conversation now ^^)

This is me so much painful giving the ViaVersion stuff Fendi 😢

Benchmark it yourself
balmy sorrel
which of all the classes? @undone narwhal

wtf why are you compressing 50 chars string
frigid ember
is there sth faster than gzip
gleaming helm
And realistically speaking data is SOOO CHEAP
frigid ember
i saidnan example
gleaming helm
And GZIP's dictionary will likely result in very minimal compression ratios possible
I wouldn't even bother compressing that data

still a small amount to be honest

lets say i have a complex model

you need 1 million 1kb files to equate to 1 gigabyte
frigid ember
do u recomend compressing
sturdy oar
not for that size order
gleaming helm
Oh oh you're compressing models for your game?
frigid ember
im jist imagining
gleaming helm
Well you're only going to decompress once so
frigid ember
some small optimization
gleaming helm
It's not a huge deal
frigid ember
on start up
undone narwhal
@balmy sorrel your plugin.yml, onEnable and one of the command class please
balmy sorrel
ok

it compresses to ancustom format
sturdy oar
Optimizing something that small could even just increase the total load
frigid ember
and can decompress and read that
undone narwhal
Thanks
gleaming helm
That's really just quite dumb tbh
frigid ember
why
gleaming helm
You're fussing about 1kb
gleaming helm
you need millions of files of that size to make a difference
OBJ files are quite small, but they're also quite easily compressible
Not a lot of entropy
frigid ember
how do i compress it
gleaming helm
With. GZIP.
frigid ember
why should i not then
gleaming helm
Or your favorite algorithm.
frigid ember
u just said dont
sturdy oar
Retrooper
gleaming helm
Well
frigid ember
??
gleaming helm
It doesn't really matter
sturdy oar
this is an XY problem tbh
gleaming helm
^
frigid ember
why
sturdy oar
what are you even compressing
gleaming helm
It's annoying as fuck to go back and forth with you
Because you exclude useful details
About your poorly worded questions
keen compass
the only reason you should be compressing something is because you intend to send it over the network
keen compass
if its just going to remain on the same hardware it originated from no point in compressing it
balmy sorrel
@undone narwhal I have things in Spanish because I speak Spanish, if you don't understand something tell me and I will tell you what it means without any problem
gleaming helm
@keen compass Or your file is so large that you're concerned about it taking too much space on cold storage
keen compass
@gleaming helm that is true too but that isn't very common though usually lol
frigid ember
donf
gleaming helm
Because your files are tiny
frigid ember
bruh
undone narwhal
@balmy sorrel Perfect, don't worry French can understand mainly Spanish
frigid ember
storage aint free byw
gleaming helm
@keen compass My uncompressed database backups are more than 30gb, compressed they're closer to like 2
Storage is REALLY FUCKING CHEAP
these days
sturdy oar
If you want a minecraft related example of compression, go look at how the server handles and compressed unused logs into .tar.gz
frigid ember
u said its free
gleaming helm
There are better examples
frigid ember
cheap isnt free
sturdy oar
well that is a proper example , where compression may actually be useful
gleaming helm
Let's calculate
frigid ember
@keen compass My uncompressed database backups are more than 30gb, compressed they're closer to like 2
@gleaming helm why shouldnt i then
i dont see myself losing anyth
gleaming helm
Google's data storage system
Which is "expensive" with respect to industry standards
keen compass
you are just wasting cpu cycles over little gains if any at all
gleaming helm
Charges $0.026 per gigabyte-month
frigid ember
having smaller sized files
gleaming helm
You have 1 kilobyte of data
silk gate
why wouldnt you compress backups
gleaming helm
0.026/1e6 is a REALLY small number
frigid ember
Charges $0.026 per gigabyte-month
@gleaming helm expensive asf jk
keen compass
fyi, depending on the block size on the HDD, compressing it smaller the 1KB isn't going to change that it will still occupy 1KB of space
frigid ember
he said 1kb
gleaming helm
1000 bytes you said
gleaming helm
So give a more reasonable example so we can assist you better
keen compass
well my comment still is valid
gleaming helm
Because the file size actually matters
frigid ember
a char is 2 nytes
sturdy oar
@gleaming helm He still hasn't given any info about what he needs to compress... im out to be honest
frigid ember
bytes
gleaming helm
Yeah same
frigid ember
i said complex models
gleaming helm
Give some info or I'm out
gleaming helm
Dude you're so entitled
frigid ember
i gave info
sturdy oar
what does blender even have to do with spigot plugin development lol
keen compass
by default windows uses 4096 bytes for block sizes, so even if you comressed smaller then that, your file still takes up 4096bytes of space since it has to occupy a block.
frigid ember
ok
keen compass
linux it is different, don't remember what the default block size is for ext4
and then Mac's have a different assignment as well lol
either way though, if you are dealing with files that are no more then say 10MB or so. probably shouldn't worry about compressing it. Unless you really are dealing with millions of files
keen compass
I mean, still probably shouldn't worry about it unless you are going to send it over the network
frigid ember
i do actually
keen compass
but then you just compress it at the time you are going to though
frigid ember
the derver will send to clients
gleaming helm
So you're now telling me that you're sending .obj files real time
That is about the dumbest idea I've ever heard
keen compass
anything sent over the network is real-time
gleaming helm
Yeah it sends a byte representation of the world state
frigid ember
why cant i send world data
keen compass
you can, just not particularly wise to send game models over the network as is lol
frigid ember
lol
i said server sends to client
ok so i am pretty new to this, and this might be a stupid question, but is it possible to reduce tps lag by making players invisible?
keen compass
@frigid ember on a hub server that actually can help with client lag, but not server lag

sturdy oar
i would need an opinion
frigid ember
what
sturdy oar
Well i'm generating a sphere
gleaming helm
@frigid ember you can't figure out why cosine needs a paremeter so shut up lol
ok
Lemme guess, you want to determine a "grid" of points around the sphere?
gleaming helm
Ping when you're ready
keen compass
@frigid ember I just don't really care why someone wants to do something lol. If someone is going to make something and its not an optimal way, well then so be it. Who is it for me to correct everyones software 😛
gleaming helm
Or just DM works too
keen compass
have to learn at some point XD
frigid ember
also him when u dm:
gleaming helm
This is after me unsuccessfully explaining the unit circle
frigid ember
😂 lmao
gleaming helm
After about 30 minutes of attempting
And not because my explaination is bad
Because I know of at least one other person here who also knows why the cosine function take a parameter
Who failed to explain it
In a way you would understand
keen compass
Oh there was math earlier o.o
gleaming helm
And him essentially acting entitled to responses
sturdy oar
@gleaming helm So I've worked on this small library a lot, however i've never made anyone actually good give an opinion to it. How i generate a sphere is done this way:
I generate a circle which stands on the (minecraft) Y axis. I then calculate a set of points that make up half a circumference. From that half circumference i loop through each point and make another circle on the X and Z axis at the height of the picked point. This goes until the bottom is reached and I have a full circle. A shitty image is attached:
gleaming helm
mmm no
well from what I'm understanding you want to do
I don't really understand
What exactly are you trying to do?
sturdy oar
A sphere from the center
gleaming helm
Are you trying to create a grid of points that lie on a sphere?
naive goblet
You’re trying to make a sphere starting from top to bottom formed like a spiral
frigid ember
noice wats the lib
sturdy oar
I have made this so far, however i don't know if there is a less CPU expensive calculation
naive goblet
Oow
gleaming helm
The best way to do it is
So first create all of the circles
On the Y axis
And like cache the radius and Y position
And then for each of those circles calculate the x and z position
gleaming helm
Also just so you know you can spawn particles async (at least on paper)
sturdy oar
of course i do
gleaming helm
So you can run all of your calculation async
sturdy oar
anyway the particles was just a visualization sample
gleaming helm
Although it really should be quite fast to calculate either way
sturdy oar
the library isn't bound to spigot at all
tiny dagger
vectors instead of sin/cos 👀
sturdy oar
gleaming helm
Vectors still use sin/cos under the hood lmfao
And if you use vectors you're recalculating either x, y, or z
So that's actually a lot slower
tiny dagger
not that kind of vectors
keen compass
if you want to optimize, just know you only need to iterate 1/8th of the sphere and can then just mirror it. Depending on what you are doing
sturdy oar
is mirroring worth it'
tiny dagger
the calculation spread across ticks 👀
gleaming helm
^
That true
Spreading out the calculation doesn't make it any faster
Just hides the problem
sturdy oar
I also avoided using any stream
keen compass
mirroring doesn't really take any processing. Just need some basic math to know all the other points once you know where 1/8th of the sphere is at
gleaming helm
Actually generating the 8th sphere thing isn't really super effective. The standard java trig functions cache values
And will mirror them appropriately
keen compass
ah yeah
tiny dagger
calculate the sphere loc then just offset it??
gleaming helm
That also doesn't help at all @tiny dagger
You're still executing 3 additions per point
sturdy oar
The sphere is the hardest one i had to do so far
keen compass
once you actually learn the tricks to it though
you will find that it really isn't all that hard lol
and easy to optimize XD
keen compass
well then you will retain that knowledge even better then
frigid ember
yea
undone narwhal
We don't really learn how to make a sphere, and in most case we need something else cause it's too heavy
frigid ember
cos of this virus all school sht delayed
keen compass
but, all you need to know is where the center of the sphere is going to be at, and then you should already know the radius. which is how large it extends out and upwards
sturdy oar
yes radius and center is all i have, and all I need
keen compass
and then its just some math to get the 1/8th of the sphere slice
undone narwhal
Retrooper, you can learn math online like dumbly fast
frigid ember
not fast
keen compass
once you have that slice, mirroring is just rotating it
sturdy oar
well not really
frigid ember
takes time
sturdy oar
remove the fast part
frigid ember
and understanding and its not easy
sturdy oar
you can't simply skip the whole math that comes before
frigid ember
its not like watch a video and i instantly get it
we are different people and differently too
sturdy oar
Everyone should kinda stay on his level and master what he can do currently
there's no need to push too far
frigid ember
yeah
undone narwhal
In my mind, if you have the computer logic math a ridiculous easy
frigid ember
i didnt learn those trigonometric functions yet ik basics alr but kevin is just making fun
keen compass
not everyone grasps trigonometry if there isn't anyone to really address their questions. Sure you can watch a video but its not like you can just pause the video and just ask someone on the spot a question in regards to what you are learning XD

computer logic?

It's a stretch to say you know the basics

Google exists though lol
frigid ember
then dont make fun
keen compass
remembering formula's for certain things makes it a whole lot easier to do things with math 😛
