random thought: isn't it possible to optimize Math.abs by removing the flag bit, instead of doing an if statement, effectively making it a branchless method

random thought: isn't it possible to optimize Math.abs by removing the flag bit,...
the flag bit?
grave mason
echo basalt
the flag bit?
for signed numbers, there's just a bit saying if it's negative or not
grave mason
https://paste.jeff-media.com
echo basalt
unsigned numbers use that bit to extend the number's max value
grave mason
can this be a problem?
echo basalt
basic example:
ubyte (255) is -127 (byte)
ubyte (128) is 128 (byte)
00000001 -> 1
10000001 -> -1
00000010 -> 2
10000010 -> -2
for natural numbers, the left-most bit indicates if it's negative or not
so my theory is that we can just set that bit to 0
instead of doing an if statement
theoretically it should be faster when interpreted in assembly
but tbh javac probably does that automatically

people do it in funky ways in assembly
tender shard
It's an anvil inventory, no?
it's a normal inventory that has "anvil" as inventory type. so no, it cannot break or sth
tranquil viper
Alright thanks!
echo basalt
like subtracting one, comparing both versions and then having fun
echo basalt
tender shard
system scope is very bad practice and then having it inside the basedir is even worse
tender shard
bitmask or something
i doubt that you'll find a faster way than the builtin Math class
java isn't C
echo basalt
I mean yeah but bit math operates the same
tender shard
as said, how would you even find out whether the number is positive? it's not like you could do "boolean isNegative = isLeftMostBitOne()" in java

you can get it from Runtime

Runtime.getRuntime().totalMemory() is the allocated amount
Runtime.getRuntime().freeMemory() gets the amount left

you can greate a generic array with reflection
grave mason
Is there a way to spawn a dropped item client side? 1.18.2
tender shard
Array.newInstance
but
it requires you to have the class
which you don't have in a generic method
so you'd also need to pass the class to your method
e.g. like this:
public <T extends ConfigurationSerializable> T[] deserializer(Class<T> clazz, String base64) {
then you can create your array like this:
T[] items = Array.newInstance(clazz, size);
it's not possible without casting the class, because of type erasure
if you don't wanna pass the class, all you can do is to use an Object[] instead of T[]
alternatively, you could pass an array of the expected return type
lethal python
is there a way i can store data associated with a player without making a hashmap or using a database
is there a built in way of storing data in the player
tender shard
alternatively, you could pass an array of the expected return type
anway, you have to pass SOMETHING. otherwise java simply cannot know the class of T
tender shard
is there a built in way of storing data in the player
yes, sure
tender shard
is there a built in way of storing data in the player
PersistentDataContainer
lethal python
woah
tender shard
Player#getPersistentDataContainer
tender shard
as persistent as something can be I guess
it gets saved in the world files
like at the same place where it stores your inventory, your health, your food level, etc
tender shard
"a bit"
lethal python
u can add stuf to
tender shard
yeah but it uses "NamespacedKeys" as key
a NamespacedKey is in the format "pluginname:variablename"
lethal python
i've used a namespaced key for something already
tender shard
chilly fox
Hi
lethal python
so i could store an INT in the player if i wanted to
tender shard
sure
tender shard
tiny example:
String surname = "Alex";
PersistentDataContainer pdc = player.getPersistentDataContainer();
NamespacedKey surnameKey = new NamespacedKey(myPlugin, "surname");
pdc.set(surnameKey, PersistentDataType.STRING, surname);
NO
internally PDC uses NBT anyway
lethal python
lol
lethal python
oh ok
so right now in my plugin i've got a hashmap to keep track of what players have a gui open
i will use this instead
this solves a lot of problems
cause now i can get data about the player in every event
tender shard
why would you need to store that persistently though?
hexed hatch
Honestly I think a hashmap is a better approach if you're tracking guis
tender shard
player's dont have GUIs open across server restarts
hexed hatch
because you don't need to be modifying the player's nbt object and guis being open don't need to be persisted
lethal python
i need to keep track of who has what ID open
hexed hatch
hashmap can do that fine
tender shard
anyway, to store a single integer on the player object, PDC is perfect for that
lethal python
ok thank you
minor otter
How could I get the value of a custom item tag of an itemstack
Like I want to give myself some random item in game like stone{test:1} for example and get that value through code
tender shard
are you talking about NBT tags?
drowsy helm
nbt
minor otter
yes
tender shard
is there a reason why you don't use PDC tags instead?
NMS is not part of the API and it requires you to either use NMS or a third party library (which will also use NMS)
minor otter
Can you give yourself an item with a PersistentDataType in game?
tender shard
hm in theory yes
PDC is simply also just an NBT tag called "BukkitValues" or "PublicBukkitValues"
so basically something like
stone{BukkitValues:{"myplugin:test":1}}
minor otter
makes sense to me, ill try it out
tender shard
then you can get the item's PersistentDataContainer and then get the value associated with the namespacedkey "myplugin:test"
or as said, you simply use NBTAPI
which is probably easier in this case but you'd have to rely on a third party library
minor otter
how would I stop this from potentially providing a nullpointerexception?
tender shard
you checked "has" so it can never throw an NPE
alternatively, use "getOrDefault"
but in this case, you can safely ignore that warning
minor otter
I thought so but the warning kept persisting to I decided to ask ๐
tender shard
btw the NBT tag for the PDC values on items is called "PublicBukkitValues"
minor otter
okay ill try it out in game real quick
tender shard
tender shard
to get rid of the warning, you could also do something like this:
Integer myValue = pdc.get(...);
if(myValue != null) {
doYourStuff();
}
the NPE can happen when you try to turn an Integer into an int
but if you treat it as Integer instead of int, you can do a nullcheck yourself
tender shard
Can anyone help with this?
why aren't you using mojang mappings?
tender shard
what MC version are you using?
grave mason
1.18.2
tender shard
mojang mappings allow you to use the proper names instead of method names like "a.b" etc
btw I think the method you're looking for is "setDisplayName" and not "setCustomName"
grave mason
This is the only what shows up
tender shard
hm okay then the method is probably named "c" or "b" or "x" or sth
so yeah I definitely recommend mojang mappings
then all methods and fields will suddenly have proper names
tender shard

grave mason
do i need to run that buildtool thing?
tender shard
yes
the "--remapped" part is the important thing
if you wouldn't have to do it, it wouldn't be in the blog post ๐
grave mason
i never got that buildtool to work
tender shard
you just download the .jar
then you open a command prompt in that folder
and then you just enter "java -jar BuildTools.jar --rev 1.18.2 --remapped"
and then you can get a beer because it takes like 5 minutes
this explains in detail on how to run buildtools https://www.spigotmc.org/wiki/buildtools/
but basically it's just "download, open command prompt, enter the command, wait, done"
grave mason

hexed hatch
too bad
tender shard
you learn nms just for it to break in the next update
unless you use mojang mappings
hexed hatch
that won't work
lethal python
only because of bukkit
tender shard
what if i want to send someone an inventory that's 9 rows big
then you can do Bukkit.createInventory(null, 9)
delicate lynx
forgot mojang mappings exist lol
lethal python
mfnalex i was told that didn't work
tender shard
of course it works
lethal python
like it didn't let you send more than the double chest size
tender shard
true but 9 is less than 54
oh
you said rows
sorry my bad
yeah that won't work
lethal python
you used to be able to though
tender shard
no
lethal python
and now with custom font textures it would be SO good to be able to make 9 row inventories
delicate lynx
I don't think that was ever possible?
hexed hatch
actually it was possible to some extent
tender shard
it was ALWAYS a multiple of 9 and max 54
lethal python
no
hexed hatch
wrong, it was possible
lethal python
you used to be able to make glitched inventories
tender shard
when?
lethal python
with more rows
hexed hatch
and it bled out of the inventory texture space
lethal python
ye
delicate lynx
oh with triple chests?
tender shard
when?
hexed hatch
if you forced 3 chests together, you could get a larger inventory
lethal python
gizmonster can you imagine making a custom font texture for that
and implementing triple chests as a plugin
tender shard
hm didnt know that
lethal python
well, can nms do it?
lethal python
i will have to learn it
hexed hatch
do it
hexed hatch
if you get me a beer sure
tender shard
"wireless pissing" that would be great
tender shard
if you get me a beer sure
I already asked for a beer myself in #general a second ago lol
delicate lynx
1.13 fixed triple chests
tender shard
1.13 fixed triple chests
then it makes sense that I claimed it wasnt possible because I only started in 1.13 lol
delicate lynx
they only spawned in dungeons, so they were kinda not known to a lot of people
lethal python
1.13 fixed triple chests
on what level are they fixed, could i still technically send a player a 7 row inventory?
delicate lynx
that I have no idea
1.13 added chests to be placed next to each other, so not sure what they exactly did
lethal python
oh in that case
hexed hatch
let me see if they still exist in the current version
lethal python
probably a lazy fix
hexed hatch
one moment
hexed hatch
because the hybrid chest could still be possible to force into the game
lethal python
if it is i am totally gonna use this
tender shard
I miss the beta 1.3 days
hexed hatch
gizmonster are u gonna do nms o_o
maybe we'll see it's a long life

grave mason
I runned that Buildtool thing but what do i need to do with that spigot-1.18.2.jar ?
grave mason
why did i build it ?
tender shard
to get it installed to your local maven repository
buildtools already did that for you
you can now just copy paste the pom.xml stuff from the blog post
and then you have mojang mappings
lethal python
what did you try
tender shard
they used google
hexed hatch
debug stick, putting a left or right state chest on the side of a double chest used to make this occur
hexed hatch
and while it's been patched since the debug stick's introduction
lethal python
if it's possible to force the glitched ui to appear if you somehow create an inventory that's 63 big
hexed hatch
I guess I could dig around nms
delicate lynx
honestly it's not even a bad idea to try with, trying to get a custom GUI
lethal python
also another question, where is a players enderchest inventory stored
delicate lynx
in their playerdata
hexed hatch
just in their player nbt file
lethal python
ok
hexed hatch
but it's completely accessible via the spigot api so don't do anything stupid
hexed hatch
of course you are
delicate lynx
titles can't be changed after creation
hexed hatch
pretty sure the title is not changeable but I could be wrong
lethal python
can i replace the enderchest inventory with a different inventory
grave mason

minor otter
But I also see no erros in logs or in intellij
tender shard
please try the latest version of your plugin and let me know if it prints the message

the code you sent is fucked up anyway
you are casting your listener's "this" to plugin
that cannot work
you definitely have got console errors
ClassCastException
public class PlayerJoinRun implements Listener{
NamespacedKey key = new NamespacedKey((Plugin) this, "test");
"this" is not a Plugin
"this" is a PlayerJoinRun instance
you probably got an exception in console when you plugin enabled
grave mason
yeah that's a bit complicated
Then it becomes almost impossible for me
tender shard
Then it becomes almost impossible for me
what do you need NMS for anyway?
grave mason
I wanted to drop an item that is client side
To like preview something
If you know what I mean :-)
tender shard
okay why does it need to be client side?
if it really must be 100% client side, it indeed requires NMS
grave mason
okay why does it need to be client side?
Because each player can choose a different item
tender shard
that's no problem in theory, you can spawn different items and show them only to certain players
Entity#hide
or was it Player#hideEntity?
one of those
grave mason
Can you hide a entity for a specific player?
tender shard
(it's draft api though)
that means it's basically the opposite of deprecated lol
basically it means "not 100% finished yet"
but it'll work fine and it also won't change
so it's fine to use
minor otter
you definitely have got console errors
idk whats up with console I didnt get any errors
tender shard
you did get errors

yes https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#hideE...
But here i have not "hideEntity"
tender shard
you did get errors
scroll up
tender shard
But here i have not "hideEntity"
hideEntity is a method declared for Player, not Entity
tender shard
np
tender shard
yes, true. of course you can use NMS instead but NMS is really a pain in the ass
let me show you my code that I use for "fake entities"
check out the "createHologram" method
and the "showEntityToPlayer" method
grave mason
Ah thanks i will check tomorrow
tender shard
oki
grave mason
Then I have to constantly update it for every player
And if i do it on the other method, if there are like 100 players online then there are like 100 dropped items
And then for everyone needs to be updated
To hide
tender shard
yeah true. in this case NMS is better. I thought you had maybe 4 or 5 different items
anyway, I know it's a pain in the ass to switch to remapped but once you've done that... your code will always work in future versions
no need to adjust it for every update etc
grave mason
True
tender shard
you just have to rename all your class references once
e.g. PacketPlayOut.... is now always Clientbound...Packet
grave mason
But most of time i see spigot forum with code

I suggest to just look at the net.minecraft.network.protocol package or what's it called
most packets have a self explaining name

I have a command and i wanna have tab completion for it's subcommands
tender shard
you can create a new class that implements TabCompleter
or make your commandexecutor implement that
quaint mantle
it does
tender shard
similar to onCommand, there's a onTabComplete method
then from that, you can just return a List<String> with the tab completions
quaint mantle
and i register all that with CommandMap?
tender shard
you do not need to mess with any commandmap at all
quaint mantle
yea but it makes command handlers easier
paper viper
what
tender shard
public void onEnable() {
getCommand("test").setExecutor(myCommandExecutor);
getCommand("test").setTabCompletor(myTabCompletor);
?
are you talking about the PluginManager's SimpleCommandMap?
quaint mantle
yes
tender shard
you shouldn't touch that unless you have good reasons to do so
and registering a normal command + tab complete definitely is not a good reason
because you can easily do that without reflection
quaint mantle
```java
public void onEnable() {
getCommand("test").setExecutor(myCommandExecu...
so i should just do this then?

yes of course

tender shard
no idea why you thought about touching the commandmap
tender shard
any1? <:YEP:916138227226783775>
I have no idea but
what exactly are you trying to do?
quaint mantle

that must have been one hell of a shitty tutorial tbh
tall dragon
what exactly are you trying to do?
i am trying to allow cows to spawn without any grass
tender shard
hmmm
I'm bored anyway so I'll just dig through some NMS, maybe I'll find something useful
tall dragon
the lil piece of code is bassically all it took for 1.8 :/
tender shard
only thing I found yet is the static checkMushroomSpawnRules method
tall dragon
and some code to replace the entity
tender shard
so Mob has a "checkSpawnRules" method
the BaseSpawner checks that method before spawning anything

Anyone know a working custom skull API that works in 1.18.2?
tender shard
tall dragon
thats annoying me
next zinc
jesus that was quick
tall dragon
so how will i go about to change that 
tender shard
jesus that was quick
yeah because it's from my lib lol
next zinc
Lmao
tender shard
so how will i go about to change that <:Hmmm:671947816574386238>
yeah well
I don't think you can
next zinc
tysm
tender shard
np
tender shard
yes, there's events for spawners when they attempt to spawn stuff
but you cannot simply override this method
it's now a static method in the ANimal class itself
tender shard
well thanks for looking into it anyway ๐
np, maybe I'm overlooking something but I fear it's not as simple as it was in 1.8
tender shard
Is there a way to use the library by getting a jar of it?
well normally you should just add it to your pom.xml or build.gradle
but sure you can also just download it
1 sec
next zinc
never was able to get that working on eclipse
tender shard
tender shard
never was able to get that working on eclipse
yeah eclipse's maven integration is shitty

well thats a first for me. where a newer version restricts me from doing something that was once possible
next zinc
tysm
tender shard
I 100% recommend trying out intelliJ, you won't regret it
next zinc
I used it once
tender shard
and also directly switch to maven
here's a blog post I wrote to get a working setup with intellij + maven
next zinc
but that was a long time ago and used eclipse more so I decided to stick with it but since I'm using more libraries and such now I might just do it
tender shard
once you got that working you never wanna go back to eclipse + "build artifacts"
next zinc
lmao
tender shard
I also used only eclipse back in the days
and I hated maven because I couldnt get it to work in eclipse
then one day I simply tried intelliJ
i hated it because I had no idea about maven
then someone explained it to me and since then I never opened eclipse again lol
tall dragon
i used eclipse for 2 hours. and i was done with it, downloaded intellij never looked back
paper viper
coming back, i realize how much I fucking hate both maven and gradle because of how inconveinant they are
tender shard

yeah the more libraries etc you use, the higher is your need to use maven or gradle lol
tender shard

lol good one
paper viper
it exponentially gets slower the more libraries you add
next zinc
Eclipse just seems easier to use at first to me hence why I stuck with it
paper viper
compared to the golang built in package system its so much worse

I also have a university email address but I am too lazy to renew it before the last minute of the license has been used lol
in fact I have an unlimited amount of university email addresses

I tried intellij I hated it and never looked back
Ofcourse I'm in the minority I'm sure it's probably ok when you get used to it

what are you trying to do?
next zinc
I basically want to set an ItemStack as a custom head
tender shard
you want to place it in the world?
or you want to get an ItemStack with a custom texture into an inventory etc?
next zinc
I want to be able to give a player a customized player head
and them have it in their inventory
tender shard
okay so SkullUtils.getHead("someBase64String") gets you an itemstack
then you can just do player.getInvenotry().addItem(...)
next zinc
So I don't gotta do any fancy initalization?
tender shard
nooo those are all static methods
next zinc
that makes life so much easier
next zinc
tender shard
exactly
tender shard
ItemStack head = SkullUtils.getHead("eyJ015135af....");
tender shard
np
btw since you don't use maven - you have to "shade" the lib into your plugin. Not sure how that works in eclipse without maven
you basically have to tell eclipse to "put the library into your .jar" lol
with maven that's only like one additional line, but not sure how it works in eclipse without maven
next zinc
Usually putting the jar into the build path works
tender shard
oh oki
tender shard
alrighty
next zinc
Thats strange
The string is causing an error
The method getBase64Texture(SkullMeta) in the type SkullUtils is not applicable for the arguments (String)
tender shard
what's your code?
as said, it works like this:
ItemStack myCustomHead = SkullUtils.getHead("afwuawfkuawfgkawfu (the base64 string)");
ItemStack fCore = SkullUtils.getBase64Texture("eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzc1YmNhMWFmNWNiMTU1N2MxNzk0ZDIzZDkwN2RmMTE1OTMyMGUxNGViYTA1ODFjMjUxODdkYmViMjJiYTJjYyJ9fX0=");
getBase64Texture is to extract the base64 texture from an existing skull
tender shard
```java
ItemStack myCustomHead = SkullUtils.getHead("afwuawfkuawfgkawfu (the ba...
do it like this
tender shard
ItemStack fCore = SkullUtils.getHead("eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzc1YmNhMWFmNWNiMTU1N2MxNzk0ZDIzZDkwN2RmMTE1OTMyMGUxNGViYTA1ODFjMjUxODdkYmViMjJiYTJjYyJ9fX0=");
the first method is to convert fCore back into the base64 string
so basically the opposite of what you want
tender shard
```java
ItemStack fCore = SkullUtils.getHead("eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybC...
just do this ^
tender shard
yeah it's a bit misleading but actually it makes sense
you want to GET a head FROM base64, so you use getHead
next zinc
Didn't realize base64 was the value so that makes sense now
tender shard
if you want to to do the opposite - get a BASE64 FROM a head, you'd use getBase64Texture
tender shard
Didn't realize base64 was the value so that makes sense now
oh yeah base64 is the weird string lol
tender shard
my bet is - you'll get a ClassNotFoundException because eclipse didn'T shade it ๐
let's see
tender shard
?paste it
undone axleBOT
tender shard
?paste the complete log
undone axleBOT
undone axleBOT
tender shard
yep you have to tell eclipse to "shade" that library
no idea how that works
as said I only use maven to handle that automatically
I think instead of "Add jar" you have to use "Add external jar"
next zinc
I hope so
tender shard
if not, this is the proper time to switch to maven ๐
tender shard
๐
it's really not complicated
in fact it makes your life so much easier
it's only complicated the first 30 minutes
next zinc
true
tender shard
I still remember when someone wanted to talk me into maven
next zinc
better to set it up and be easy afterwards I guess then pure pain
tender shard
and I was like "ugh what a bullshit"
next zinc
I know that maven is super useful and good
I just know that its not something im knowledgable in
which I guess I don't like very much lmao
tender shard
yes I know that feel. someone once converted one of my plugins to a maven project
and I was so upset because I didnt understand anything about it
thank god this dude took much of his time to explain it to me
next zinc
That dude was insanely nice
tender shard
but there you can see that I also didn't get maven to work properly with eclipse
when I swithed to intelliJ, everything was simply working lol
next zinc
yeah
tender shard
I was totally unfriendly to him at first lol
I was so upset that it didnt work
in my view, he changed something and then everything stopped working lol
little did I know that it was mine and eclipse's fault lol
tender shard
well
next zinc
at least from when I first used it
tender shard
left and right are some menus and in the middle there's your source code lol
not sooo different ๐
tender shard
I recommend that you create a totally new project
and just write a tiny plugin
just to get started with maven
then when you got that working, you can copy/paste your current project into it
next zinc
Smart
Woah
wait
in plugin.yml author is supposed to be in quotes
I have never done that
tender shard
doesn't matter
next zinc
o ok
next zinc
got it
and for the main import if I made my group id io.github.darkenedfusion I would import main as:
io.github.darkenedfusion.HelloWorldPlugin
yes, that looks good
your package names does NOT have to match your maven groupID but it's quite common to use matching names
tender shard
if I was you, I would use the following names:
groupId: io.github.darkenedfusion
artifactId: HelloWorldPlugin
main class name: io.github.helloworldplugin.Main
next zinc
why remove the darkenedfusion part?
next zinc
ah
gotcha
ok then its basically the same as eclipse for getting the main class
just wanted to be extra sure so I don't spend a decade figuring out why it wouldn't work and having to find that
tender shard
normally your package name should be something like "yourname.projectname.Main" or similar
some people would argue that "Main" is not a good name for the main class but lets just ignore this for now
next zinc
So once you have all of that, thats pretty much it?
tender shard
the huge advantage when using maven is: when you want to add for example my library, all you have to do is to add the URL to my repository to <repositories> and the name and version of the library in <dependencies> and that's basically it lol
next zinc
Yeah
I see so many libraries have that maven thing
so it limited my choices when there was no jar
tender shard
tbh any library that does NOT provide a maven artifact is probably shitty
next zinc
noted
The Skull Manager that I had before was a file that I found
worked perfectly but I dont remember it having a maven implementation
nvm it did
guess there just was another way of implementing it
tender shard
you can always also just directly download the .jar files from the maven repository
like the file I sent you was just a link to the file that maven would have downloaded automatically
but maven can also handle stuff like "include that library in your final plugin .jar" etc
next zinc
ah
tender shard
that's called "shading"
for example you have the spigot api. you add that as dependency but obviously your plugin should not actually include spigot
because the server already has the spigot .jar
but my library, you must include that in your .jar because the server doesn't have it yet
and yeah that's called "shading" - adding libraries and also putting them into your .jar
tender shard
it's quite important. there are libraries that you can use without shading - when that library is a standalone plugin
for example WordEdit - you can use that without shading because that pugin is installed on the server already
but other stuff aren't a plugin and your plugin has to "bring it along"
but yeah I highly recommend that you just follow that blog post and create a really simply "Hello world" plugin. like something that says "hello player" when you joined. once you got that going with intellij + maven, we can convert your existing plugin to work with maven. it'll only take like 5 minutes
tender shard
it's at "<projectFolder>/target"
tender shard
yep lol
next zinc
only slight thing I can think of
tender shard
it's a bit weird to setup because you need the pom.xml but after that, just double click "package" and that's it
next zinc
since in eclipse when I exported the file it went directly into my servers plugin folder
dang
tender shard
oh wait
you don't have a <build> section in your pom yet
one second I'll send an example
next zinc
I do
I think
<?xml version="1.0" encoding="UTF-8"?>

<version>3.2.2</version>
<configuration>
<outputDirectory>C:\mctest\plugins</outputDirectory>
<finalName>Test</finalName>
</configuration>
</plugin>
</plugins>
should look like this then
this will save it at C:\mctest\pugins\Test.jar
next zinc
the group and artifact thing dont change right?
tender shard
you mean when you choose a custom folder for it to build?
no that has nothing to do with each other
tender shard
you can basically choose ANY group and artifact ID, it would never affect your final plugin jar
group id and artifact ID are more like "meta data"
you only have to worry about those if other stuff uses your plugin as library
tender shard
perfect ๐
okay now the tricky part is to turn your existing project into a working maven project
next zinc
I mean it seems simple enough now
tender shard
since you used eclipse, your whole build setup is probably "messed up" from mavens perspective
next zinc
I hope
tender shard
if you like, you can just upload your whole project to github and I'll turn it into a structure that maven undertsands
tender shard
sure, no problem
next zinc
Doesn't intelliJ have an auto update github thing as well?
tender shard
of course
next zinc
awesome
tender shard
btw if you are looking for sth and cannot find it:
press shift twice quickly
it opens a menu where you can enter ANYTHING and it'll show you where it is
tender shard
when I tried intellij the first time, I hated it because I couldnt just do File -> Export .jar
next zinc
I might've accidently deleted the plugin file
tender shard
huh
the plugin file? or the source code
if you accidently deleted the source code, that's... fucking inconvenient lol
tender shard
๐
next zinc
the source folder somehow ended up going into my plugins folder
which I mistuck as some random plugins config folder
Alright
Prepare for the most professional looking code you've ever witnessed
tender shard
lol np
can you give me write access for a few minutes?
I'm too lazy to fork it and do a pull request
my github name is mfnalex
next zinc
I totally know how to do that
tender shard
did you add any dependencies besides spigot api?
next zinc
only other thing was ur jar file
tender shard
oki perfect
okay so I'll quickly explain what I'm doing
first of all, your code has to be in src/main/jave
right now it's in a folder called PheonixNetwork
maven wants it to be in src/main/java though
your plugin.yml has to be in src/main/resources
the rule basically is:
all files etc go to resources, and all source code goes to java folder
then I'll just create a pom.xml
and basically that's it
next zinc
Seems simple enough
So whenever creating a new project
put the spigot file in the resources folder
tender shard
oh and I'll adjust your package name
right now you use io.github.DarkenedFusion
but you probably will do another plugin sometime
so package name should rather be io.github.darkenedfusion.<pluginname>
next zinc
So that will fetch the plugins name without me manually typing it?
next zinc
so just placeholder text
next zinc
kk
tender shard
ok check out this
as you can see, spigot has <scope>provided
that means, we do not need to shade spigot because the server already runs it anyway
however my library is <scope>compile
that means maven will actually include my library in your plugin
that's the shading thing I told you about
tender shard
seems to be working, one sec
next zinc
๐
tender shard
ok I opened a pull request on github
just accept that and now your github repo is ready to go
did you upload the code using intelliJ?
next zinc
I uploaded it with eclipse
tender shard
ok
go to your repo on github, then accept my pull request
basically you have to merge it
tender shard
okay now, do this in IntelliJ:
File -> New -> Project from Version Control
then paste your github URL: https://github.com/DarkenedFusion/PhoenixNetwork
and baaam, now you should have a working maven project in intelliJ
and yeah you can build it by double clicking on maven -> package
oh btw that's something I also would like to explain:
in the maven menu, you have things like "clean", "compile", "package", etc
clean basically means "clean up the whole build folder".
"compile" means "compile all java files" but then you only have a bunch of compiled files, not a wokring plugin
"package" however is the same as "compile" but it also puts everything into a .jar file and includes all the libraries (the "shading part")
so if you want to get a working jar, "package" is the thing you wanna use
package = compile + include needed libraries + put it into a .jar file
next zinc
Interesting
