i want to get inventory items from config any method?
@frigid ember create your own (de)serializer or use an existing one
vernal spruce
Doesnt config api have getItemstack now? Why not use that
torn robin
@frigid ember what have you tried?
median swift
sturdy oar
?
frigid ember
i tried to loop
zinc ingot
its fine
sturdy oar
why are you not doing new ItemStack(Material.valueOf(this.plugin.getConfig().getString("GUI.item"))) ?
frigid ember
i need to allow users to make more item stack
sturdy oar
then you need object serialization
frigid ember
can you explain me please
sturdy oar
something like
GUI:
- item: STONE
lore:
- 'Message'
- 'Other Message'
amount: 6
enchanted: false
- item: RED_STAINED_GLASS
lore: []
amount: 6
enchanted: true
something like this
will require YAML Deserialization\Serialization
sturdy oar
look at ConfigurationSerializable
sturdy oar
then learn YAML I guess
I can give you an example from my code but it's probably not the best to follow
frigid ember
so i think it will register flags i guss
hot girder
final everywhere
frigid ember
hmm
hot girder
I use final only when is required
frigid ember
private final List<ItemStack> items = new ArrayList<>();
private ItemStack head;
private ItemStack chest;
private ItemStack legs;
private ItemStack boots;
public SInventory(Map<String, Object> config) {
List<ItemStack> items = (List<ItemStack>) config.get("inventory");
for (ItemStack item : items) {
if (item != null) {
this.items.add(item);
}
}
this.head = (ItemStack) config.get("head");
this.chest = (ItemStack) config.get("chest");
this.legs = (ItemStack) config.get("legs");
this.boots = (ItemStack) config.get("boots");
}
public static SInventory valueOf(Map<String, Object> config) {
return new SInventory(config);
}
public static SInventory deserialize(Map<String, Object> config) {
return new SInventory(config);
}
@Override
public Map<String, Object> serialize() {
Map<String, Object> back = new HashMap<>();
back.put("inventory", this.items);
back.put("head", this.head);
back.put("chest", this.chest);
back.put("legs", this.legs);
back.put("boots", this.boots);
return back;
}```whill this work?
naive goblet
why are you not doing
new ItemStack(Material.valueOf(this.plugin.getConfig().getString("GUI.item")))?
Material#matchMaterial() over valueOf?
hot girder
deserialize items using ItemStack.deserialize
and serialize using ItemStack#serialize
hot girder
Idk what is the difference between Material.matchMaterial and Material.valueOf
valueOf is the Enum default method
sturdy oar
valueOF needs exactly to be the name
matchMaterial tries to match without being equals
frigid ember
thanks for your help it worked
sturdy oar
no way
frigid ember
??
oof dosnt works it opened plane inventory no items LOL
no errors tho
@sturdy oar i understand now you mean `
sturdy oar
don't ping plz
frigid ember
- ==: org.bukkit.inventory.ItemStack
type: STONE
- ==: org.bukkit.inventory.ItemStack
type: BLAZE_POWDER``` if a config looks like this and we need to deserialize it right?You can remove "==: org.bukkit.inventory.ItemStack"
frigid ember
- item: STONE
lore:
- 'Message'
- 'Other Message'
amount: 6
enchanted: false
- item: RED_STAINED_GLASS
lore: []
amount: 6
enchanted: true``` i need to covert this to java codeit says null
hoary parcel
You need the == so that bukkit knows which class to deserislize
frigid ember
hmm i will try
sturdy oar
is there any non-official way to bypass Minecraft's max book length?
hot girder
You need the == so that bukkit knows which class to deserislize
@hoary parcel yea, but is possible use ItemStack.deserislize
so, == is not necessary
hoary parcel
More effort
frigid ember
for (Map<String,Object> itemlist : data.getMapList("itemlist")) {

I've done some of the tests for https://wiki.vg/Protocol#Entity_Velocity but it seems has a delay.
In my localhost it has delay between 40-55 which is server tick rate but it's not the same result for my dedicated.
Is the velocity packet communicate server which cause delay?

packets will be delayed from chunk sending hogging up the queues.
chrome edge
Is it same for all of the packets?
timid valley
yes
we spoke to mojang a few days ago about that to help improve the issue
its on their list now
chrome edge
I'm happy to hear that. Minecraft code will be better soon thanks god
timid valley
and mojang has hired someone to specifically look at reworking the network
chrome edge
So mojang has started to listen minecraft server community. It's great
timid valley
yes, Helen, the community manager, has been doing great things 🙂
Paper teams been working with Mojang to identify a lot of issues we've fixed to get fixed in Vanilla
todays snapshot is another result of those discussions
chrome edge
Thanks for that and good luck! I'll try to support paper and spigot for that. You guys have done a lot of things for the community. I'm really happy for that.
sturdy oar
is Spigot working with Mojang as well
timid valley
in the talks we have, no. but md5 does have other connections to them, but i dont know how much discussion they have.
chrome edge
I don't know the details but I think yes. If you consider, spigot team found a lot of bugs.
Aikar is there any async update for the future?
Like performance for servers and game
timid valley
yes, but far far future lol
mojang does want to get rid of the concept of a main thread
id expect at most per-world threads though
chrome edge
finally lol
timid valley
while it is possible to divide up a world into multiple threads (I've designed the solution already), its a much more ambitious project
if it wasn't for plugins, I could of done it already 😛 plugins is what makes it hard
chrome edge
Oh that's interesting. I've done some process before the mojang lol
harsh anvil
shouldve just thrown the whole notch crap out of the window and make minecraft 2.0

that prob would of been worse. at least now their usage of streams isnt deep enough that they can be reverted

paper basin
anybody available to give some help with packets?
I'm currently listening to an incoming packet from the client with this code:
@Sharable
public class DropHandler extends ChannelDuplexHandler{
DropHandler(){}
public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception{
if (msg instanceof PacketPlayInBlockDig) {
PacketPlayInBlockDig packet = (PacketPlayInBlockDig) msg;
if (packet.d() == EnumPlayerDigType.DROP_ITEM) {
// more code
return;
}
}
super.channelRead(ctx, msg);
}
}
// Main code:
ChannelPipeline pipeline = ((CraftPlayer) p).getHandle().playerConnection.networkManager.channel.pipeline();
pipeline.addBefore("packet_handler", "drop_handler", new DropHandler());
However, after executing the code if the right packet is received, the minecraft server stills handle this packet even with the return; statement in the code.
Anybody have got an idea of why doesn't it work and how to fix this?
timid valley
i think you gotta throw some special exception
worn temple
depends on size and what you are doing
paper basin
uh
no way to do this in a... cleaner way? x)
frigid ember
while(it.hasNext()) it.next() or a foreach array
timid valley
performance wise prob identical. iterator has a small allocation each invocation though
timid valley
so if its super hot, using random accesse optimized loop avoids any allocations
worn temple
a stream is even better than iterator or array
timid valley
your better off writing a proper plugin for it @paper basin this is wrong approach. itll create desync
worn temple
Or even, reactively processing, but not really possible on bukkit without resyncing
paper basin
I just need to know if the player drops the whole stack or only one item
timid valley
??? your listening to block dig packet
there is a PlayerDropItemEvent
or something like it
paper basin
yup, this is the one which handle drop
chrome edge
._.
frigid ember
aikar is that u irl
paper basin
PlayerDropItemEvent does not gives the stack size unfortunately :/
timid valley
registering packet handlers to do stuff you should be able to do by api is silly
you can do .getItem().getAmount() ?
paper basin
what if it was a stack of only one item?
I want to know if it's CTRL + DROPKEY or DROPKEY
but you're right, it should be in the API, I will create a request
timid valley
InventoryInteractEvent
paper basin
no, from the game, not from the inventory 😅
timid valley
talking about Q rigth?
paper basin
yup
timid valley
is that really a block dig packet? wtf
paper basin
yup x)
this is also why PlayerInteractEvent is called when you drop an item
because every single PacketPlayInBlockDig calls a PlayerInteractEvent
that's a Spigot bug which has been reported for a long time
timid valley
yeah hmm no event for this
or well, the event that fires doesnt receive the boolean that expressed intent

@thorny isle index out of bounds. the list its checking is empty
Also, please post it on pastebin, or the official hastebin instance
An ad filled rehost is pretty questionable

@thorny isle index out of bounds. the list its checking is empty
@worn temple
I assume by that response you aren't a programmer and didn't code the plugin. Contact the plugin author as this is a code issue
thorny isle
im a plugin author but I'm new and I don't know what you mean
frigid ember
Hey guys, if I do
p.getInventory().addItem(Const.NETHER_STAR);
and I have the itemstack as static and final in a seperate class, would this be misuse of static?
thorny isle
Do you want someone to give "Nether star"? @frigid ember
worn temple
Whatever list is being accessed com.macioszektv.brushextreme.Main.onCommand(Main.java:33) on that line, is empty, and you are trying to retrieve the first item in it. since nothing is in the list, it is an out of bounds exception: https://www.geeksforgeeks.org/understanding-array-indexoutofbounds-exception-in-java/
Yeah, its static abuse
frigid ember
@worn temple if I put it in an enum would that be static abuse as well?
worn temple
@frigid ember Make a static method that instantiates a new itemstack
thorny isle
Whatever list is being accessed
com.macioszektv.brushextreme.Main.onCommand(Main.java:33)on that line, is empty, and you are trying to retrieve the first item in it. since nothing is in the list, it is an out of bounds exception: https://www.geeksforgeeks.org/understanding-array-indexoutofbounds-exception-in-java/
@worn temple Line 33 is:
Player target = Bukkit.getPlayer(args[0]);
since you don't care about state, its technically fine
@thorny isle args array is empty.
thorny isle
I would like when i write a command without args, it shows usage
worn temple
Well, you're trying to get the player by the args, so don't do that?
If you are so new to java that you do not understand these basic concepts, I highly highly recommend you take a step back and learn, at least the basics of, java and then come back to spigot/bukkit. Here is a great resource for learning: https://www.mooc.fi/en/
timid valley
@frigid ember this is the worst community to ask about static use. it's fine to do that, however id name the class something more useful than Const, but also do .clone() before adding to inventory as you dont want multiple inventories linking to the same itemstack
otherwise it runs risk of amount changing affecting everyone who has a copy
timid valley
but, your not gonna get much benefit if its just a plain nether star vs new ItemStack(Material.NETHER_STAR)
worn temple
Hell, my early plugins are chock full of static abuse
timid valley
but if you're configuring lore and such too, then yes it's good to store templates as ready to clone items
tiny dagger
they're probabily fine for inventories of type gui too 🤔

Theoretically it should be
leaden girder
Got any ideas?
naive goblet
Could you give more context for your scenario?
frigid ember
how do i give plugins permissions to my friends in my hamachi server

I guess you kind of want to rearrange and manage indexes in a list

idk how permissionsex work at all
frigid ember
can u send me the link? for 1.15.2
leaden girder
I have different upgrades for my hoe plugin and I would like the upgrades and levels of those upgrades to show up in the lore. I don't want to individually add each upgrade and level in the lore so I just wanted to grab the levels through the placeholder but I would need to have multiple lines
naive goblet
You’d have to start with comparing the list before transforming the placeholder to after
And then take action to the changes
frigid ember
why didnt java not make a string a primitive datatype
strange grove
subtle blade
because it's not primitive
naive goblet
Its really just an array of chars
subtle blade
It's almost one of those special cases because its literals make it seem kind of like a primitive
naive goblet

Only... it's not lol

Strings are just a sequence of chars and it’s immutable

Hii can someone help? Pls i recently did a Network, once i already connected all server i had a problem in My survival server because i can’t do /spawn, when i try it just appear a message “You do not have permission to execute this command” i guess is sth in the bungee config, i already set spawnpoint in survival and tried with op and without op
naive goblet
Do you have a permission plugin?
marble valve
In Survival, yes i use GroupManager, actually, without network i mean, Survival as a single server worked perfectly, without problems but once i connected it to bungee, the trouble appeared
naive goblet
Is /spawn a bungee command or what?
marble valve
Is a /spawn command from essentials but it seems like bungee don’t allow players to use the command
I mean in Survival, i use essentials and in this server, i can’t use it because bungee don’t allow me idk why

c# string is primitive
@subtle blade
and @naive goblet
in c# you can do
string a =“a”;
if(a == “a”) {
}```ik
subtle blade
Strings are classes in C#
frigid ember
primitive
subtle blade
They too are immutable
tiny dagger
in java works too tho
frigid ember
== is conparing instances
frigid ember
why didnt java do it
subtle blade
frigid ember
would u want it
subtle blade
Not really. Serves for confusion
tiny dagger
no
frigid ember
instead of abandoning it and continuing windows edition they maintain and update it still in java
tiny dagger
java is probabily what made them so popular lol
how much of minecraft did you played before using mods?
exactly
tiny dagger
java was used before too 🤔
naive goblet
Skip it python ftw

They have a team at Microsoft dedicated to the Windows version

Mojang will remain on Java, as they should

According to stackoverflow java is 3rd most popular programming language
frigid ember
so?
naive goblet
No need to switch it out yet
frigid ember
im talking about whats better
tiny dagger
c++ and python are the other 2 i guess
naive goblet
Better in what way?
tiny dagger
then go use that :p
frigid ember
?
for game modding c# would be best
or game deving c# is better than java
use opengl and ez
if one wants to make plugins one is forced to using java, as mc server is java, mc isnt even open src, this is terrible
choco: “i dont use anything thats not open src”
alao choco: plays mc
subtle blade
You're not forced to use Java
subtle blade
Bukkit is designed to allow for plugin loading in different languages. You just have to be willing to implement it
frigid ember
java is best option for mc currently
subtle blade
Also, LWJGL is a library for Java to interact natively with OpenGL so I don't understand your concerns
A large majority of that library is native methods
subtle blade
It really isn't
frigid ember
c# inbuilt libs are better
subtle blade
C# has its flaws as well
frigid ember
name one
compared to java
its nice not having to use a method to compare strings imo xd
“a” == “a”
naive goblet
why have that
tiny dagger
this is how java works deal with it
naive goblet
easier to seperate reference comparison to a value or content comparison. If you're going to compare languages do it in a factual way
naive goblet
Well I shouldn't perhaps say too much as I don't code in C# but go with what u like idc
naive goblet
ur factual arguments 😫
naive goblet
why would i

so basically you looked on some stuff c# does and based on that you already made your opinion?
good to hear
frigid ember
?
worn temple
@frigid ember in java .equals is a value comparison, but == is an instance (memory location) comparison. so, while == could be "faster to type" its wrong.
timid valley
ChocoToday at 4:23 PM
They have a team at Microsoft dedicated to the Windows version
ChocoToday at 4:24 PM
Mojang will remain on Java, as they should
@subtle blade this is not true. Literally was just said a few days ago (in private) that the teams are united now. each dev when they add a feature, they add it to bedrock and java at same time, both platforms are unified now in development.
worn temple
No, its only correct if you actually want instance comparison
naive goblet
Lol like that shortcut is saving ur life
subtle blade
Unified in development, absolutely
There are still two teams working on the two differing projects
frigid ember
get yo facts ryte
timid valley
It's not separate teams. The same developer adds it to both bedrock and java.
straight from mojangs mouth.
frigid ember
i thought so
subtle blade

String a = new String("a");
String a1 = new String("a");
a == a1; //false
a.equals(a1); //true

timid valley
Finally got automated testing setup, hiring people with dedicated roles to improving existing elements
worn temple
Its the same in C#
frigid ember
no
worn temple
frigid ember
you don’t kno c#
worn temple
I do tho
worn temple
In c# its not instance, its reference comparison, but they can be differing just like in java
frigid ember
i didnt say String i said string btw
timid valley
@frigid ember don't rely on it. relies on jvm interning common strings
tiny dagger
i think "a" == "a" is true in java too
frigid ember
i said string
worn temple
Again, its value vs instance for java, and value vs reference for c#.
worn temple
In both cases, while most times it may be the same, it is actually different
naive goblet
Retrooper I mean personally I’d probably try out C# if I were to develop a game as it’s confirmed to be better. So fair enough
frigid ember
🙂
I don’t have time to preach all pros im glad u realized tho
a game was an example
naive goblet
Idk rlly know much about C# and tbf this comparison discussion is really unnecessary
frigid ember
ok
worn temple
@tiny dagger "a" == "a" is only true because "a" is cached in the String constant pool. If you did new String("a") == new String("a") it'd be false. This is the same for java and C#
tiny dagger
i feel like someone is gonna get hypixel threats again 👀
worn temple
Still applies
naive goblet
If C# has the == that replaces .equals() use it? Nothing more nothing less why even debate about it
worn temple
yes, string is primitive, and String is class. its still the same thing
obtuse rose
"a" == "a"
Sometimes true, sometimes false, depends on caching
you'll see some code kinda work using == in Java
but you absolutely shouldn't
worn temple
== and .Equals are not the same. It will not always be true. 99.99999% of the time, yes, it will be, but it depends on caching
its referential
sturdy oar
String a = "bruh"
String b = a;
assert(a == b) : "bruh ur java broken";```this is what string == string is for
frigid ember
im coding c# dude
sturdy oar
smh Microsoft Java
worn temple
Its the same in C#, it's usually true, but not always
frigid ember
microsoft owns mc
native shore
wtf
frigid ember
¯_(ツ)_/¯
worn temple
Where as .Equals is always true
because you are doing referential vs value comparison
native shore
You dont compare Java Strings with ==
frigid ember
who said java
sturdy oar
nobody said that
worn temple
I never said always false or always true. its a different type of comparison, because it relies on caching, it can be true or it can be false
sturdy oar
I actually compare them character by character smh
subtle blade
man this discussion is going literally nowhere lol
naive goblet
^
worn temple
.Equals is always always correct because it does a value comparison not instance (for java) or referential (for C#)
native shore
who said java
literally the code block a few messages above yours..
String = Java
string = C#
worn temple
@subtle blade I know. People just don't understand the underlying principles of why these two options exist.
@native shore string is just the primitive in c#, but String also exists just like in java there is boolean and Boolean
timid valley
does it a lot smarter than that lol
sturdy oar
yeah I don't look smart
worn temple
No, it does bit logic on it, no need to go down to chars, it compares the raw bits @sturdy oar
tiny dagger
you saw nothing 👀
sturdy oar
let me delete
obtuse rose
I think Java compares hash of the strings?
sturdy oar
well first it checks the length i guess
tiny dagger
yea
naive goblet
@frigid ember I might sound dumb but does all primitives in C# have wrappers?
timid valley
just open it in your IDE and look
the codes right on front of you if you have IDE open
tiny dagger
memory length hash otherwise a for loop to check it 🤔
sturdy oar
oh yeah it actually checks length first
obtuse rose
ofc you need to check length first 😛
naive goblet
So C# has String and string and Java only has String 🤨
sturdy oar
it does compare character by character
obtuse rose
public boolean equals(Object anObject) {
if (this == anObject) {
return true;
}
if (anObject instanceof String) {
String anotherString = (String)anObject;
int n = value.length;
if (n == anotherString.value.length) {
char v1[] = value;
char v2[] = anotherString.value;
int i = 0;
while (n-- != 0) {
if (v1[i] != v2[i])
return false;
i++;
}
return true;
}
}
return false;
}
It makes some sense but I mean does it matter if it’s a prim or not
tiny dagger
afterall a string is an array of chars
frigid ember
imo it should be prim
timid valley
string will prob become a valuetype in vahalla in 40 years
naive goblet
¯_(ツ)_/¯
sturdy oar
the hell is Valhalla
tiny dagger
a new assassins creed game fendi
timid valley
worn temple
in java == actually compares the memory location, an instance comparison. Because of caching, that memory location can be the same for multiple strings. so "a" == "a" would be true since its cached in the constant pool and new String("a") == new String("a)" would be false. Whereas .equals will compare the actual values of the strings (or objects) so both examples would return true because the instancing doesn't matter.
C# is similar, == is a referential comparison. so whether both objects/primitives in question reference the same thing (similar to instancing, but slightly different at the low level), while .Equals does a value comparison.
obtuse rose
why do you want primitive string?
worn temple
@sturdy oar They are the same thing in basically all respects.

Javascripts comparisons are much different because its weakly typed.

Only 3.

PhP has ===
worn temple

always prefer === in JS, == just .toStrings() both sides

so == can really hurt performance if toString() is heavy

how do i remove my name so the server thinks im joining for the first time?
i think it's throwing new people in the wild instead of server spawn and i need to confirm it

delete your playerdata from the main world
join
to find your uuid
then find your_uuid.dat in the world
tiny dagger
yeah
naive goblet
Just the main world?
frigid ember
couldnt find the file
tiny dagger
frigid ember
well its supposed to spawn in a different world then you warp to the main
ty
i found it
naive goblet
Idm the player data should still be stored in the level worl
frigid ember
yeah theres no playerdata saved in the multiverse worlds i guesds
here's hoping it works
tiny dagger
then you haven't deleted it from main world
frigid ember
no i did
worn temple
Gotta delete the player data from the playerdata folder, also have to go through any plugins (like essentials) that stores additional player data.
worn temple
Also, never ever ever ever use /reload. that's for developers only and should never be used in production
frigid ember
would it possibly take a complete restart to change it?
worn temple
Well, you need a complete restart for plugins. Full /stop and then start.
frigid ember
yeah but its not a plugin file
As someone who's already taken some courses in Python, would you guys recommend TheNewBoston for Java tutorials?
worn temple
But again, you need to go through all your plugins and make sure if any of them store player data, to remove your data.
naive goblet
Reload is nice
worn temple
Again, even if not a plugin, never ever ever use /reload
Its literally only meant for developers
naive goblet
Would be even nicer if plugins used onEnable properly
frigid ember
what problems can it cause?
naive goblet
And onDisable

memory leaks, bad shutdown of plugins, mishandling of so many things.
@naive goblet Its not plugins not using it correctly, its the fact that it fucks with the classloader.
Doesn't matter if you use onenable/disable correctly, it still breaks a ton of shit
naive goblet
Oh nvm I was thinking of plug man
worn temple
because classloaders
and fuck plugman, even if you want to mess with classloaders, don't use plugmans, at least use BileTools as it gives plugins a chance to attempt to shutdown correctly, verses plugman which just completely wipes the classloader
frigid ember
why did spigot change inventory gui system
naive goblet
Did they?
frigid ember
yea
TheNewBoston? Recommended?
unloas, load, restart
plugins
all there
and open src
worn temple
But plugman and bile are and other plugins similar to them should only ever be used by developers. They are not meant for production servers or server owners that don't develop plugins.
naive goblet
That’s true
frigid ember
beuh
naive goblet
Still useful
worn temple
It does some seriously fucked up things with the classloader and can break so damn many things.
naive goblet
Weird it didn’t do it for me
frigid ember
ok nvm ig lol
worn temple
I'm not hating, its a solution to a problem that doesn't exist.
frigid ember
then u fix it
worn temple
Just stop the server and restart it.
frigid ember
fork it
naive goblet
Plugman works fine with anything except for the plugins that doesn’t have a proper onDisable
frigid ember
not all big servers can do restarts
worn temple
@frigid ember Yes, let me just rewrite all of java's classloading system. That's what the issue is, its java's classloading combined with how bukkit loads plugins. Its not something to jut "rewrite"
worn temple
its server owners being too lazy to stop their server properly because of a lack of understanding of the JVM.
frigid ember
i told u
ugh there's so many plugins that could be holding uuids. im suprised it didn't treat me like a new player in any way by just deleting the playerdata file
worn temple
Well yeah, @frigid ember because plugins need to hold their own data and can't read and write to the player data files like that lol
But that's why, while the server itself will think you have joined for the first time, whatever plugin is handling teleporting new players isn't because it relies on its own data
naive goblet
I swear ur laughing out loud rn
worn temple
nah, actually little aggravated because I can't figure out a networking issue.
naive goblet
Ok gl ig
worn temple
¯_(ツ)_/¯
frigid ember
new idea
worn temple
Think its actually on discord's end.
frigid ember
anyone want to do me a favor and pop on my server for 2 seconds?
see where it spawns you?
i changed a suspect plugin
but its only been reported once
naive goblet
Can’t rn
naive goblet
Well I’m going to use plugman even more now
naive goblet
Yep
naive goblet
Never got any memory leaks or some stuff being messed up
frigid ember
yup
can anyone pop on for just a sec. 2min thing
i mean the value i changed was TeleportNewbies: true to false
thats probably it
naive goblet
Why not use EssentialsSpawn?
Doesnt that teleport u into a specific world regarding other stuff
frigid ember
i am using Wild
naive goblet
Wth is that
frigid ember
and i think either multiverse or essentials was set up to start you off at spawn
i mean it worked before
but wild i've installed awhile after
its /wild
so i think it was throwing newbies at random places
naive goblet
Config wild then

Would a TreeMap descendingMap sort the map on keys, highest to lowest?
odd knoll
Pretty sure a tree map goes lowest to highest. I'd recommend testing incase I'm wrong and if it does, you can reverse it using Collections.reverseOrder().
odd knoll
No..
red kernel
Nope it wouldn't
odd knoll
Like, Maps.newTreeMap(Collections.reverseOrder())
Different people have different ways, some prefer using new TreeMap styling, so you could do that instead, but that's the gist.
@wanton magnet I'd suggest just thinking of something basic you'd want to do, changing some mechanics or making your own and then exploring what you need, what you can do with it. Pick something where you'd need some events and then maybe to mess with some items. I always find experimentation can be the fastest way to learn.
tiny pebble
Anyone know where I can find out how to apply ItemMeta to an item? I'm just doing a simple sort of thing like giving a stick to someone though I want it to have specific properties.
odd knoll
Can't personally say I've watched any, but apparently The Source Code's are good.
dusty topaz
ItemStack#setItemMeta()
tiny pebble
Thanks 😛
ashen stirrup
I'm confused on Collections.reverseOrder() - the demonstrations I found online all use ArrayLists etc.
odd knoll
I'm getting sooo confused with my own code here.
I don't get how this is even working.
Ok, I'd recommend waiting for someone else that might have used TreeMaps a bit more.
ashen stirrup
I just need the values to be descending.
naive goblet
TreeMap<K, V>#descendingMap() ?
ashen stirrup
My question was just if descendingMap sorts on Values
dusty topaz
descendingMap()
Returns a reverse order view of the mappings contained in this map.
java.lang.IllegalArgumentException: Meta of class tanku.dev.commands.customitems.WhackerStick$1 not created by org.bukkit.craftbukkit.v1_15_R1.inventory.CraftItemFactory
Sadly I do get this error when applying the ItemMeta. I've tried several ways to apply it but it may just be an error in my Java knowledge, not sure. I know that it says it isn't created by CraftBukkit, but then how else would I get custom properties 🤔
ashen stirrup
When I try to initialize the players HashMap with descendingMap, it makes me change the map to a NavigableMap .
dusty topaz
@tiny pebble are you making your own ItemMeta lol
tiny pebble
At first I was trying to yes, as I thought that was the way to fill out what properties I want haha
tiny pebble
ItemStack whacker = new ItemStack(Material.STICK);
whacker.setItemMeta(new ItemMeta() {//all the itemmeta methods});
I'm sure it has to do with the fact that I did new ItemMeta(), though I tried doing it in a separate class as well. Guess I just don't understand ItemMeta
dusty topaz
ItemMeta is an interface
worn temple
oh god, don't do new ItemMeta().
dusty topaz
you use ItemStack#getItemMeta
worn temple
^
its not so much not understanding ItemMeta. Its understanding what an interface is. And in this case, how to obtain an itemmeta object
tiny pebble
Ahha alright, so it was indeed my Java knowledge
Yeah, I have a lack of understanding on what an interface is sadly, though I've read up and am learning 😐
worn temple
https://www.mooc.fi/en/ < great resource for learning java. I believe the first lesson has a whole section about interfaces and inheritance. (I mean, I know it covers it, just dunno how far in it is)
tiny pebble
Ah neat. I've had some good resources about learning Java though none ever told me the difference between an interface and a class, kinda lame
sturdy oar
is using ternary operator to avoid if condition fine?
like i gotta increase this counter value by 1 if a condition is true
so i do something like counter += (condition) ? 1 : 0
worn temple
ternary operator is just a shorter way of writing out a conditional that can affect a variable. so its fine.
raven robin
Fendi, that's fine, as long as you know what you're writing.
sturdy oar
i guess I know 😅
raven robin
So do people here use MCDev? I'm trying to use a Redirect in a Mixin, and though the plugin used to verify the target field, I can't get it to do it anymore. Does anyone know how to make it validate that field?
sturdy oar
MCDev? you mean the IntelliJ Plugin?
raven robin
Yep
sturdy oar
yeah I do use it indeed
worn temple
not really super needed if you don't mind setting up the boilerplate
sturdy oar
i have no time to write pom.xml tbh
raven robin
Fendi, can you get it to validate the "target" field in a redirect statement?
sturdy oar
sorry can't help you
worn temple
I just copy it from other projects of mine
sturdy oar
i don't know what you mean lol
I just basically use that plugin to generate listeners and configs
worn temple
You can just make your own template project with IJ now
sturdy oar
you mean a maven archetype?
raven robin
Like this: @Redirect(method="spawnEntities", at = @At(value = "INVOKE", target = "Lnet/minecraft/entity/mob/MobEntity;initialize()V"))
worn temple
No, like a legit full on project template.
worn temple
I have no idea what you are doing tbh.
Haven't used it since it was pretty early and was just reducing manual work on boilerplate
raven robin
I'm trying to write a Mixin.
worn temple
annotations are pure java, I just have no idea what the point of this is

neat orbit
Hi. I run a Minecraft server with Multicraft Spigot and it takes more than 7 seconds for Joining World and to be able to join the server, what affects the span of login. It should only be 1 second at most
worn temple
SpingBoot. Its annoying when you start, but once you understand spring well, its amazing
sturdy oar
Wasn't Spring for web development
raven robin
I'm writing a Fabric mod, but since Spigot uses Mixins, I thought you guys might know something about this.
sturdy oar
or I remember something else
worn temple
Yeah, it is, I use spring for web dev. Just showing an example of something that uses annotations heavily.
The Android API also uses it a lot
sturdy oar
Aikar's ACF uses lot of annotations
worn temple
@raven robin Honestly, you're way better off going to the fabric help server. Not sure why you started here tbh.
@neat orbit So so many things can effect login time: mods, resource packs, auth, connection speed, location, etc etc.
So, no, it shouldn't be "only 1 second at most" Its completely dependent on so many different working parts.
Its kinda like how a spigot server with no plugins can boot really fast, but a spigot server with many plugins will take longer to boot. Its just the nature of interconnected dynamic systems.
raven robin
Nova, I did start there; I just didn't get a response. I went here because I thought you'd be familiar with Mixins and/or the plugin.
worn temple
Its been so long since I've used that IJ plugin, it only reduced boilerplate at the time. ¯_(ツ)_/¯
sturdy oar
I mean the thing that I was trying to say , is that like ""default"" java looks better usually to me
or maybe it's just me not being able to use stuff properly , idk.
like I prefer the right way here for example
worn temple
I mean, depends heavily on what you define as "default" java. Like this reactive code: https://owo.oooooooooooooo.ooo/i/nmik.png
tiny pebble
so... is it right to have all of my properties filled out in a separate Java class that implements ItemMeta? and if so, how would I thus apply those properties to my itemstack?
I mean I got ItemStack.setItemMeta(), and I know getItemMeta just returns the current ItemMeta of the item...
ahha, sorry about these questions. i know i'm a bit new but this is how i'm going to learn (meaning i'm going to learn through plugins etc), so if you don't want to answer you don't have to 😛
worn temple
Don't make your own class that implements ItemMeta.
You aren't understanding how inheritance and interfaces work.
worn temple
Just retrieve the ItemMeta with ItemStack#getItemMeta()
tiny pebble
my main misunderstanding there is what would go in the ()? i'm just confused how i would state the properties i want basically
worn temple
Methods do not always need parameters
tiny pebble
then i guess re-wording my question, how would i state the properties just in general using ItemStack#getItemMeta()?

@raven robin Spigot does not use Mixins at all. That system was created for Sponge. You may have some luck asking Sponge too if Fabric is inactive atm.
tiny pebble
Is it possible to edit the size of every mob via Spigot? Either by editing hitbox/model or the genuine size (other than slime/magma), even if severely difficult?
tiny pebble
😛
timid valley
@tiny pebble all that does is adjust their collision boxes, the size internal that is
theyll appear same on client
tiny pebble
so i could change their collision boxes server side, and then use a resource pack to change the model?
zinc ingot
it won't change the interaction of the player with the mob
timid valley
good luck, not sure if thats possible client side

@fathom shard right click it in the hotbar (as in their inventory is open), or right clicking with the item in hand?

Possible that diamond character is messing it up then

frigid ember
@worn temple
Player target = Bukkit.getPlayer(args[0]);

if I do this and check for null, but if the player is offline and I do

will this cause errors?
worn temple
It will only error if the args array is empty OR if you attempt to get the display name if it is null (IndexOutOfBoundsException and NullPointerException respectively)
frigid ember
When can the display name be null?

Its marked @NotNull so it can never be null

You got it working for the island display did you not?
frigid ember
No, that's from the server I'm trying to copy
And I can't find this character anywhere
worn temple
You probably just need to escape it as a code rather than include the actual symbol.
That symbol could be the benzene ring \\U23E3
The symbol you're currently using I assume is \\U25C8
Just include it in your string like: https://owo.oooooooooooooo.ooo/i/tjsa.png
I'm gonna keep looking for the symbol you're trying to find tho
opal bay
that's one hell of a tld
worn temple
The TLD is just ooo

just the power domain https://en.wikipedia.org/wiki/.OOO
opal bay
that's some power
worn temple
@frigid ember yeah, can't seem to find the symbol, but this one will probably look better anyway: https://www.compart.com/en/unicode/U+29F0
Include it in your string like so: \\U29F0
Don't remove the double slashes

also banning stone on the server is a bit extreme

Lmao, it's just an example

Also seriously don't advise the first one because of the forcing of cancellation
frozen cedar
We were comparing it to if around if around if
subtle blade
You force it to true, then force it to false
If another listener cancels it at a lower priority, you're going to break compat
More often than not you don't want to setCancelled(false)

I've developed a plugin that allows players to ride and control Ravagers. When riding, the player that is mounted to the Ravager cannot see the Ravager match the rotation of the player - it resets to a neutral position (possibly yaw and pitch 0,0.) However, when another player watches the player riding a Ravager, they can see the Ravager rotating just fine. I presume this is a packets issue but I have yet to figure out why this is happening. If you have any insight, I would greatly appreciate it. Thanks!

There's definitely some way of NMSing the function

That’s gonna be deep in the server logic

You’re gonna have to do some bytecode manipulation or actually mod the spigot

I've hacked the permissions before to add wildcard support in my perm plugin
I just made a custom permissionsbase that extends the API one and injected it into the player
nimble stump
But there isn’t going to be an API injection you can do there
It’s gonna be hard coded in a method somewhere
pastel fox
Ah heck okay ty
In that case, annoying but I'll just set the actual blocks to air and send fake block changes to the players who can't pass through
I was hoping for an easy way to avoid that because I'll have to store and keep updating the original block data
