does the plugin use shadowJar?

does the plugin use shadowJar?
is that like a gradle thing or smthng?

For example, my IntelliJ automatically copies my build jars into the plugins folder, even if the server is running.

I just copy pasted it from my other project
tender shard
btw you manually changed the outputDirectory in line 53
that's not a good idea
you should use the maven-jar-plugin to change the final output .jar

like this:

<artifactId>maven-jar-plugin</artifactId>
<version>3.2.2</version>
<configuration>
<outputDirectory>C:\mctest\plugins</outputDirectory>

because you might have other goals / executions / plugins that alter the .jar made by the specialsource plugin
only the maven-jar-plugin should be reponsible for moving your final .jar

your world folder has a "session.lock" file

k so
after a server restart everything works fine
i unload world
i load world

i unload again
load again and Exception
after unloading/loading once i can restart server and it works once more

since it only happens once on startup

its just gross
you shouldn't need to reflectively get all extending classes for a kit plugin, when its likely all in their project anyways

sounds like a fucked up design but easily possible
- get all class names from your plugin .jar like this https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/com/jeff_media/jefflib/ClassUtils.java#L122

i just wrapped it (goals, navigation control, ...) in interfaces myself so I can use it "without NMS" on spigot-api: https://github.com/JEFF-Media-GbR/JeffLib/tree/master/core/src/main/java/com/jeff_media/jefflib/ai

It may be ugly but I was too lazy to call register on like 70 classes
No
tender shard
well
tall dragon
yeaa i once had a plugin where i had to register like 80 classes too. i used annotations there
tall dragon
and just found all annotated classes
tender shard
and if you have NMS questions, people here will answer it
but there are no javadocs or anything for NMS
you can do that if you use spigot, of course
which one I sent you isnt a class
the GOal thing?
as I said, spigot-api does not include any NMS
young knoll
It's not in the api

you have to use spigot instead of spigot-api
I literally wrote a blog post about spigot vs spigot-api like 10 minutes ago lol https://blog.jeff-media.com/bukkit-vs-spigot-api-vs-craftbukkit-vs-spigot/

the blog post wouldnt have 100 lines of text if that'd be all you need
tall dragon
time to use maven then
tender shard
Gradle?
tender shard
Then you have to run the specialsource plugin manually
heady spruce
why?
tender shard
Or learn how to make ant run arbitraty jar files over your build
tall dragon
tender shard
Okay then you gotta translate the specialsource plugin part into some kind of „exec“ thing that runs it manually
Its explained in the 1.17 announcements how to run it manually
You can also use the obfuscated names if you prefer that
But then your code will break on every update
And methods woll be called „a“, „b“, etc
tall dragon
still dont rlly understand why mojang obfuscates at all
tender shard
https://stackoverflow.com/questions/1965055/pass-a-command-line-argument-to-jar-in-an-ant-script you can use this to run the specialsource jar directly

only to release a map

You should rather use the one from your maven repo
1 sec
the .jar you should use is
~/.m2/repository/org/spigotmc/spigot/1.19.2-R0.1-SNAPSHOT/spigot-1.19.2-R0.1-SNAPSHOT-remapped-mojang.jar
or 1.19 or whatever
don't forget that you still must remap it manually after you compiled your .jar
second post, headline "NMS"
basically, download this https://repo.maven.apache.org/maven2/net/md-5/SpecialSource/1.10.0/SpecialSource-1.10.0-shaded.jar
and then run this (with 1.17 adjusted to your actual version) on your .jar after you compiled it:
java -cp $HOME/.m2/repository/net/md-5/SpecialSource/1.10.0/SpecialSource-1.10.0-shaded.jar:$HOME/.m2/repository/org/spigotmc/spigot/1.17-R0.1-SNAPSHOT/spigot-1.17-R0.1-SNAPSHOT-remapped-mojang.jar net.md_5.specialsource.SpecialSource --live -i $PLUGIN.jar -o $PLUGIN-obf.jar -m $HOME/.m2/repository/org/spigotmc/minecraft-server/1.17-R0.1-SNAPSHOT/minecraft-server-1.17-R0.1-SNAPSHOT-maps-mojang.txt --reverse
java -cp $HOME/.m2/repository/net/md-5/SpecialSource/1.10.0/SpecialSource-1.10.0-shaded.jar:$HOME/.m2/repository/org/spigotmc/spigot/1.17-R0.1-SNAPSHOT/spigot-1.17-R0.1-SNAPSHOT-remapped-obf.jar net.md_5.specialsource.SpecialSource --live -i $PLUGIN-obf.jar -o $PLUGIN.jar -m $HOME/.m2/repository/org/spigotmc/minecraft-server/1.17-R0.1-SNAPSHOT/minecraft-server-1.17-R0.1-SNAPSHOT-maps-spigot.csrg
or switch to maven and let it to all those things automatically for you
but as said, you can also put this in your ant script somehow, I sent you a link above
$PLUGIN.jar is obviously your plugin's jar name
tender shard
the .jar you should use is
```
~/.m2/repository/org/spigotmc/spigot/1.19.2-R0.1-...
here
~ is your home folder
the .m2 folder might be hidden

i wonder why md_5 didnt upload the newest specialsource to central

young knoll

vocal cloud
Husbandry involves breeding?
tender shard
you should now see the Goal class if you properly added the remapped .jar to ant
well just a tiny example, this will make all freshly spawned zombies move to 0, 64, 0
public class Test extends JavaPlugin implements Listener {
private static class MyGoal extends Goal {
private final Mob myMob;
public MyGoal(Mob myMob) {
this.myMob = myMob;
}
@Override
public boolean canUse() {
return true;
}
@Override
public void tick() {
myMob.moveTo(0,64,0);
}
}
@EventHandler
public void onSpawn(EntitySpawnEvent event) {
if(event.getEntity() instanceof Zombie) {
((CraftZombie)event.getEntity()).getHandle().goalSelector.addGoal(0, new MyGoal(((CraftZombie)event.getEntity()).getHandle()));
}
}
I swear, it's like they're targetting me specifically lol, the NMS stuff that I use, although obscure, is changed like every other update
it's crazy
I always need to change the methods that i'm reflecting
tender shard
that's why you should use remapped-mojang instead
young knoll
everything in data will be json
tender shard
in 99% of cases, just adjust the version in the mappings, and done
young knoll
It's all datapack stuff
tender shard
tick() is what actually does anything
canUse() is there to actually start your custom goal
canUse is necessary
without canUse, it wouldnt even compile
tick() isn't neccessary, but it's the method that gets called every tick while your custom goal is active
you should normally use start() and stop() instead for pathfinding
gray merlin
But isn't NMS included in the server?
tender shard
ofc it is
young knoll
Yes
tender shard
yes, because canUse is abstract in Goal
gray merlin
Then wouldn't the server need the mappings too?
young knoll
That is how an abstract class works
tender shard
Then wouldn't the server need the mappings too?
no, the server uses spigot mappings. the whole remapping thing is to turn your mojang-mapped code into spigot-mapped code, so the server can understand it
it adds the goal to the entity if it's a zombie?
kinda, yes
i dont know if it works if it's too far away from 0,64,0
just go to 10,64,10, spawn a zombie there and it should work
gray merlin
no, the server uses spigot mappings. the whole remapping thing is to turn your m...

No

1.17+
gray merlin
Ah I see
In that case i'll finish everything up with the normal mappings, push it, and make a new commit with mojmaps
thanks
young knoll
why dont we have nms in spigot api
Spigot API doesn't depend on NMS?
quiet ice
why dont we have nms in spigot api
Because NMS is ARR?
tender shard
IIRC the mappings are available since 1.15 or so, but there's no remapped version for spigot until 1.17+
quiet ice
Spigot API is (L-)GPL, and everyone knows what happens if you mix LGPL and ARR code
young knoll
I still don't know how to use SpecialSource with gradle tbf
tender shard
using maven is by far the easiest for this since spigot itself uses maven, so md made a remapping plugin for maven
tender shard
I still don't know how to use SpecialSource with gradle tbf
well you could just make gradle run the specialsource .jar manually
or use paperweight
quiet ice
Although really converting it to gradle should be a piece of cake
gray merlin
Oh, the method I was using, that caused the mojmaps conversation, seems to have been doing the exact same thing as a ctor that existed, and I happened to have a reflection for that ctor. I was under the impression they they did different things, but no.
pain.
quiet ice
Gradle is groovy
young knoll
(Or kotlin)
quiet ice
(Or kotlin)
It's more like a deranged child between kotlin and groovy imo
young knoll
I tried to use the kotlin version for a bit
quiet ice
Although I never used kotlin myself, so it could actually be kotlin
young knoll
It is so hard to find any documentation on it
quiet ice
It's hard to find any documentation on anything concerning gradle
young knoll
Kotlin is still 100x harder than Groovy in that regard
The best way to learn is to just dig through it
hasty prawn
Once you have Mojang Maps and if you know Java pretty well you can figure out the NMS stuff pretty easily

IE wtf is (X instanceof Object instance) referred to as

I thought it was just pattern variable
ivory sleet
oh the variable part is presumably called that ye
young knoll
Either way, best new feature imo :p
hasty prawn
Agreed ^
ivory sleet
agree apart from structured concurrency
young knoll
Structured who what
tender shard
it's quite easy. You can just define a name for it to aumatically cast
public boolean isEglibleEntity(Entity entity) {
if (!(entity instanceof Slime slime)) {
return false;
}
return slime.getSize() <= config.getMaxSize();
}
no need to do Slime slime = (Slime) entity
basically it only allows you to write one line less
ivory sleet
basically a paradigm that tries to address the developer's control over concurrent running code, like error handling
young knoll
People are always talking about fancy new/upcoming features like foreign memory api
And my smooth brain is just here like “Records cool”
hasty prawn
mfw I only use records when IntelliJ tells me to
young knoll
Listeners aren’t really a part of java itself
They are a spigot api thing, but other apis also use them
ivory sleet
People are always talking about fancy new/upcoming features like foreign memory ...
listeners?
I mean sort of
worldly ingot
Java makes use of the concept of listeners, yes. Though there's no "listener api"
They're generally referred to as callbacks
young knoll
Ah right
young knoll
Basically the server just invokes your listener method when certain things happen
Via evil reflection
ivory sleet
well, java does use observer/subscriber based callback patterns internally and somewhat externally also in the jdk
worldly ingot
Via evil reflection
Almost wonder if it's worth migrating to use method handles
ivory sleet
nah
worldly ingot
Curious what the performance benefits would be of that
ivory sleet
reflection is going to get reimplemented with method handles
young knoll
Heh Runtime code generation
hasty prawn
Let Paper figure that out 
ivory sleet
if that didnt happen already
and not all method handles are faster than reflective invocations
only if you do it correctly with the right method handle and strategy like iirc lambda meta factory
worldly ingot
<https://download.java.net/java/early_access/loom/docs/api/jdk.incubator.concurr...
I'm actually not a fan of this API by the way. Maybe I'll find good use for it but I find its cases are going to be niche and very specific
What I do like however is that those docs make use of the snippet tag
Which is neat :) First time I'm seeing them in action
ivory sleet
yeah
young knoll
Nothing wrong with a niche api
ivory sleet
well, apparently people have been complaining about unstructured concurrency
worldly ingot
Not at all. I just can't see myself using it
Actually, no, I can think of a case or two
ivory sleet
I think one nice usecase is when u want a thread per user (websocket or sth), subsequently not having to rely on sth like netty to make an application scalable
worldly ingot
Netty will hopefully make good use of these
ivory sleet
yeah 
fluid finch
I can't seem to manage to add a poison effect to an entity
the wither effect works perfectly fine
young knoll
What entity
tender shard
yeah for undead things, you'd need healing instead
round finch
zombie will be healed by poison
tender shard
yeah it's the other way around for them
healing potion makes damage on undead and poison makes them "healthy"
young knoll
Pretty sure that’s only for instant damage and instant health
Whereas they are just immune to poison
fluid finch
nah regen works as poison on em
gray merlin
Can we do worldgen with spigot?
young knoll
Undead
Zombies are undead mobs, harmed by the status effect Healing, healed by the status effect Instant Damage and are unaffected by Regeneration and Poison. The wither does not attack zombies. Zombies are affected by the Smite enchantment.
According to the wiki
Side note I miss pre fandom wiki
gray merlin
and are unaffected by Regeneration and Poison

Yes
The api for worldgen is somewhat basic, but you can also use NMS

yea that probs needs nms. however, disconnecting someone removes them from the server, and you need to keep them there to make them think theyre still online.
the only idea i have is to do some network bullshit to 'remove' them from the view of other players and simulate the server around them
so that anything they do gets done to a simulated copy
fleet comet
so that anything they do gets done to a simulated copy

Error Fixed
dim bronze
If I mention it every so often maybe someone will give it a try
but if you've only just learned java then it's probably not the right way to go
dim bronze
does that code actually get run? maybe it's stopping execution before it gets to that line
reef lagoon
It does get run, because 10 lines later there's horse.setColor(Horse.Color.BLACK); which does work
wary topaz
Is there any way to save the current player you are messaging to a variable?
dim bronze
is the horse tamed?
reef lagoon
I set an owner but I don't know if it does the trick, lemme see
dim bronze
haven't checked but maybe a horse can't have a saddle unless it's tamed
I imagine that's the problem
dim bronze
this is why people say learn the language before you jump into spigot. A map is a relatively simple data structure you should be aware of
wary topaz
Oh like a string?
shut field
Oh like a string?
not a string
wary topaz
Similar
shut field
map is not similar to string
reef lagoon
I imagine that's the problem
Yep it was, thanks
opal juniper
map is not similar to string
it is a data structure 
shut field
it is a data structure <:thinksmart:497966651623604225>
but not a similar data structure
wary topaz
they allow you to create a relationship between 2 objects
I cant find it in the spigot javadocs
dim bronze
in this case you could 'map' the player that ran the command to the player they want to message
dim bronze
it's because its a part of java not spigot
shut field
does anyone know how to read when the recipe book is open, and to set a recipe unavailable
smth to do with packets, I'd think
dim bronze
smth to do with packets, I'd think
I can't see any need for the server to be aware that the player has their recipe book open, so I doubt a packet is sent
Nevermind, I am incorrect
https://wiki.vg/Protocol#Update_Recipe_Book sounds like the right packet
wary topaz
dim bronze
its a bit like an array in the sense it will hold many of those relationships
so 1 to red isn't the only thing it can hold
wary topaz
I just need it to hold 1 thing though
shut field
to get the String you would do hm.get(int);
dim bronze
what about when more than 1 player messages someone?
dim bronze
yes, but you won't be the only player on the server. If more than one person runs the message command your plugin needs to keep track of who each person is messaging
if that isn't the case then there's no need for a map, just a simple Player variable for the person that the player is speaking to
wary topaz
oh
So what should I put in it?
public LastMsg(String user) {
this.user = user;
this.lastReceived = null;
this.lastSent = null;
}```
Cant I do that?Like I said, before jumping into plugin development, I'd get a good grasp of not only the syntax of java, but also how to 'think in code' to know what to write to get the computer to do what you need it to do, which will involve learning data structures like maps, lists etc.
dim bronze
```
public LastMsg(String user) {
this.user = user;
this.lastRec...
that is an option
wary topaz
Than I'll use that.
dim bronze
although I wouldn't keep track of players by their name
shut field
https://wiki.vg/Protocol#Update_Recipe_Book sounds like the right packet
is it fair to use a onPacketReceiving event for this?
i don't rlly know how to differentiate between different packets
dim bronze
yes, I would imagine so, I haven't worked with protocol lib in a while so I can't remember exactly how it deals with things
actually, you may not be able to use that packet
it's clientbound meaning the server sends it to the player
this is the one you want, and yes you'd use a receiving packet listener
sorry for sending wikivg links, it's how I've always checked it, but I know people don't like them because they make their own names for things
shut field
cool, thx
dim bronze
is there a reason you aren't using maven or gradle?
yes, but why are you using it over maven, it would make this a lot easier as the tools already exist
never used it so I can't help sorry. I imagine you are just giving it the commands to run manually, and I haven't used special source manually
I think most people saying to use ant these days are satirical. irrc you can use ant inside of maven if there is something specific you need

but if you are developing with the 1.12 api, then you want the 1.12 nms jar
dim bronze
what's the exact error?
@civic apex
ah, I don't think you should be deleting the session lock, that should get deleted when the world is unloaded as there is no need for it to be locked
civic apex
<@575028253278863369>
java.nio.channels.ClosedChannelException: null

what code is on the line the exception is thrown on

dim bronze
hmm figured so

Did you run both commands?

Reflection doesn't seem to support mojmappings does it?
hasty prawn
It doesn't
Use mojmaps to figure out what to do and then go back and change the names to Spigot's maps

In that case i'll finish everything up with the normal mappings, push it, and ma...
I was skeptic that it would, but I still tried, thus why I did this
I'll just revert everything back now, then. Thank you guys for the confirmation

unloadworld
just so we are clear, are we talking about your unloadWorld method, or boolean success = Bukkit.getServer().unloadWorld(world, save);
If we are talking about your method, which line specifically

that line
dim bronze
when do you get the location? is it tied to the old world?
dim bronze
is the world correctly loaded after the first unload?
civic apex

its correctly loaded as in i can join it yes

whats the exception when session.lock isn't deleted
this has me stumped honestly
civic apex
whats the exception when session.lock isn't deleted
lemme look at logs
dim bronze
I don't think deleting session.lock should be a solution to anything
that's your error exactly, this does not exist in a static method. You need to pass that skull texture to your method
civic apex
lemme look at logs
OverlappingFileLockException
IllegalArgumentException and NullPointerException were also thrown dont remember exactly when
fleet comet
Is there any videos I can watch to get to know NMS
dim bronze
dont just blindly copy and paste. try to understand whats happening. In this case, all that needs to change is base64Str to be the string of the texture you want to put on the head
dim bronze
IllegalArgumentException and NullPointerException were also thrown dont remember...
this is all happening on the main thread yes?
I presume so otherwise the teleports wouldn't work
civic apex
this is all happening on the main thread yes?
i think so
dim bronze
you dont call Scheduler#runTaskAsyncronously
civic apex
i remember calling stuff async, but i dont think its related
civic apex
you dont call `Scheduler#runTaskAsyncronously`
not rn
dim bronze
that looks more like hex than base64, where is it from
yes, it is
looks good to me, now you just need to set the heads owner to the gameprofile
yes,
no, theres a separate method for setting gameprofile owners
or at least there is now, back in 1.12 you need to use reflection
dim bronze
not rn
stumped at the moment. Trying to understand that error if nothing is running asynchronously as the lock should be held by the main thread and released when you want to unload it. This is definitely a more meaningful error than the last one, and by just deleting the lock seems to open you up to more problems.

if i delete the lock only one exception gets thrown, but if i dont both that and the OverlappingLockException get thrown
dim bronze
I imagine the ClosedChannelException is a result of the lock
so just deleting the file is getting rid of the meaningful error
civic apex
so just deleting the file is getting rid of the meaningful error
yes but ClosedChannelException always gets thrown
except (iirc) if i save when unloading in which case i think it just crashes

it probably isn't remapping as you think it is
there's no need for the setOwner call at the top now because the gameprofile is doing it for you. When you initialise profile, try give it the name of an empty string rather than null, maybe it doesn't like the fact the player has a null name (second arg)
GameProfile profile = new GameProfile(UUID.randomUUID(), "");
oh no
does it have the custom name?
This is 1.12
pretty sure its gameprofile

I have multiple versions for my plugin, across many versions, but when publishing, it only allows me to add one file. How would I add all the versions?
And categorize it across the versions (1.7.10 - 1.19)
dim bronze
that texture isn't valid
it doesn't point to a skin
no its not too long
if you convert from base64 -> ascii you get this json
{"textures":{"SKIN":{"url":"http://textures.minecraft.net/texture/57ccd36dc8f72adcb1f8c8e61ee82cd96ead140cf2a16a1366be9b5a8e3cc3fc"}}}
that url is 404
no
that's hex
the base64 value of the texture property contains the whole result from the skin server
which is that json
but for whatever reason that skin was deleted from the servers
@quaint mantle are you still using ant?
send your code for remapping
script
same thing 🙃

You using reflection?
Reflection is a java feature
but alright you're prob not using it then
dunno then

I have multiple (MC) Versions for my plugin, but spigot only lets me upload one file; How do I upload all the versions and categorize them?

you'd have to upload them separately afaik. is there a reason they cannot be 1 file?

Let's see...
NMS, Different APIs, Different functionalities in many GUIs, different events...

you can shade them all into 1 jar no?
you just need 1 core api and it doesn't matter how different the implementation is in each of the modules, just make sure the right module is used as the implementation and shade them all into your plugin jar

Perhaps using ant wasnt the wisest of all choices?

perhaps

trying to put https://minecraft-heads.com/custom-heads/blocks/51088-ore on a skull, any idea how?
doesnt have a player name
dim bronze
what version
arctic moth
skullmeta doesnt have the textures thing i believe

did you remap
dim bronze
i reckon you just bite the bullet and spend 5mins setting up maven instead

pretty sure you have to do PlayerEvents.MyGoal
