so how did it get to 1.9
granite stirrup
then restrict it to less than 1.5gb
cant
sage swift
"the host is really generous"
cyan bluff
How can I check if a player has permissions for a specific command?
wraith rapids
you can't restrict it but it is limited
cyan bluff
(If the command is a string)
wraith rapids
literally what
granite stirrup
its stuck on this command java -Xms128M -Xmx1500M -Dterminal.jline=false -Dterminal.ansi=true -jar server.jar
sage swift
How can I check if a player has permissions for a specific command?
Player#hasPermission
cyan bluff
ah
wraith rapids
yeah that limits the heap to 1.5gb
cyan bluff
but like does it work for the command, or does it have to be in permission format
sage swift
you can also put the permission under the command in plugin.yml if you want to directly define it
wraith rapids
an off-heap memory usage of about .5gb is fine
there is nothing to worry about there
cold tartan
is there a way to get the way a player is looking in vector form?
sage swift
Location#getDirection
wraith rapids
any issues you faced "because" of that are either the host being shit or you going crosseyed
granite stirrup
nah the host is fine
wraith rapids
it clearly isn't
shrewd totem
idk java
wraith rapids
if your server crashes with an oom after overallocating resources
shrewd totem

paper viper
wot
granite stirrup
if your server crashes with an oom after overallocating resources
nah its just a limit put in by pterodactyl
quartz anchor
you mean something like Player#sendMessage?
wraith rapids
you aren't supposed to allocate all of your available memory to the heap with pterodactyl
your issues are caused by a misconfiguration
which is unsurprising
sage swift
just means you run the method on an instance of the object
wraith rapids
talk to the host about it
sage swift
vs . which usually references static methods
granite stirrup
you aren't supposed to allocate all of your available memory to the heap with pt...
im not doing that lmao
and i think thats default
quartz anchor
just allocate below the maximum memory
paper viper
doesn't really matter to me
lol
granite stirrup
you aren't supposed to allocate all of your available memory to the heap with pt...
pterodactyl does that
wraith rapids
your host has given you 1.5gb of memory
you have allocated 1.5gb of memory to the heap
granite stirrup
yeah but theres like a overhead bit
wraith rapids
your system memory footprint consists of more than just the heap
granite stirrup
so it can go over
wraith rapids
then the overhead given to you isn't sufficient
and needs to be increased
by lowering the heap allocation
granite stirrup
the overhead is like .5gb
wraith rapids
yes
quartz anchor
dude my jre uses more than 1.5gb even i only allocated 1gb
granite stirrup
lmao why
wraith rapids
because that's how native memory works
quartz anchor
get more memory then
granite stirrup
well yeah but this is just default settings in ptero
wraith rapids
that doesn't mean it's right
anyway, i'm done with this retarded argument
do what you will
wraith rapids
that is completely irrelevant
granite stirrup
yeah but plugins use memory lmao
wraith rapids
not really
quaint mantle
why does mongo keep wanting to import from com.mongodb instead of org.mongodb
quartz anchor
it just only uses the amount of allocated memory after all

granite stirrup
also tps is low on 1.16.5
quartz anchor
no it doesn't
wraith rapids
1.16 performs significantly better than 1.14
granite stirrup
1.16 performs significantly better than 1.14
no for me
wraith rapids
you have just configured your server like ass
quartz anchor
at least it's better than 1.13
granite stirrup
for some reason spigot 1.16.5 uses less memory
wraith rapids
yes, paper uses somewhat more memory
granite stirrup
but its still quite alot 1.11 GB
wraith rapids
1.13 performs better than 1.14 mostly because of villagers and entity ai changes
cold tartan
im getting this error when I added an event:
https://pastebin.com/JtkiiKZC
i have never gotten it before so im confused
wraith rapids
1.15 performs better than 1.14 mostly because of villagers getting fixed
quartz anchor
wraith rapids
1.12 performs better than 1.14 because 1.13+ uses the shitty overengineered chunk system
quartz anchor
look at Bedwars.java:27
cold tartan
wait how is it null
quartz anchor
the manager could be null
wraith rapids
1.16 has negligible performance degradations compared to 1.15 so it still performs better than 1.14
granite stirrup
idk how ptero calculates memory tho
quartz anchor
i need code to look at bruh
wraith rapids
it calculates it poorly
cold tartan
this is the code:
ScoreboardManager manager = Bukkit.getScoreboardManager();
Scoreboard board = manager.getMainScoreboard();```the numbers it shows are irrelevant
granite stirrup
yeah but cuz its a free server on this host the tps and ram usage is high on 1.16.5
thats why i was on 1.14.4
cold tartan
yep
quartz anchor
recompile it and restart your server
quartz anchor

the final approach is to use /rl

yo it must be some magic with /rl
or maybe your plugin load before scoreboard actually loaded
cold tartan
ok
so now, im getting a different issue

Currently I have this, I want to make it so that it responds with true if the player has access to the command and false if the player doesnt have access to the command/the command is invalid. So far it works, but it for some reason doesn't work with official minecraft commands. It only responds properly to plugin commands. Also, if the player isn't OP, then it returns false for all commands, even the ones they can do.
So I just need to figure out how to make it work for minecraft commands, and how to make it work for non-op players.

Basically, I'm trying to make a commandspy plugin. I have that part done, but I also want to make it so that the command appears green when the player has permission to run it, and the command appears red when the player doesn't have said permission. Also, if it isn't a command, then it's red.
I suppose checking if the command had run successfully would also work, but I don't know how to do that either.
sullen marlin
some bad plugins will check their permissions via code, so that will cause false negatives
but the vanilla commands should work
one problem with your code is it uses getmessage which includes all arguments

Your plugin is not already disabled when that method is invoked, however there are certain API calls which you can not access from it.

hm
lemme try something
the name of the folder with the config n stuff got all messed up

so imma try resetting it
i bet thats the issue

I also recommend you rename your class from Main
eternal oxide
Something relevant to your plugin. Usually the plugin name
eternal oxide
Main is for stand alone programs where their entry point is main
eternal oxide
Plugins are simply extensions of Spigot so have no Main

cause literally 99% of my plugin dont work now lol

lol

?paste your main

ah ok
eternal oxide
also, line 29 is accessing main before its been intialized
eternal oxide
other than that and it should be BlackListCommand implements CommandExecutor 🙂
eternal oxide
and fix your getConfig() 😉
tranquil viper
and fix your getConfig() 😉
where?
eternal oxide
in your BlackListCommand
config comes from Main
so you need to set it in your constructor
FileConfiguration message;
FileConfiguration config;
public BlacklistCommand(Main main) {
this.main = main;
this.config = main.getConfig();
this.message = main.getMessages();
}```ok
so ive been doing it the way i have it in there for the message
should I change it for all my classes?
eternal oxide
yes
eternal oxide
main is only initialized when your constructor is called, however the fields are initialized on class access, before the constructor runs
eternal oxide
so trying to access main in a field will result in main being null
tranquil viper
so trying to access main in a field will result in main being null
I have one final question for you
then im done for the day
cause ive been at this for a long time
what should I make FileConfiguration as
to save the file
because its null rn so im getting an error
and I cant save directly with FileConfiguration because its a static reference
eternal oxide
FileConfiguration fc = new FileConfiguration();
File file = new File( main.getDataFolder(), "data.yml");
fc.load(file);```np

Hey folks, I am trying to replace the items in player's hand/hotbar for a few minutes, then put them back in the same position they were before. To do so, I am trying to use the "extra slots" defined by Spigot, but it is not working as expected. Could someone please explain to me if this idea makes sense? I mean, what exactly are these extra slots? Can I use them as a "backup" inventory for items that I want to save?
vagrant stratus
Couldn't you store the UUID & item in a list and use Bukkit's scheduler or something similar?
worldly ingot
extra slots aren't additional slots
the "extra slots" are just what aren't armour slots or inventory slots
i.e. a player's crafting slots
lyric briar
Couldn't you store the UUID & item in a list and use Bukkit's scheduler or somet...
I could, I am just trying to find the safest way to replace the items
I mean, I don't want to lose what items the player had in hands if the server, for example, crashes.
lyric briar
extra slots aren't additional slots
Thank you for your answer
vagrant stratus
I'm not really sure 🤔
A hacky solution would be using a .yml file or similar... but that would end up with a lot of reading/writing..
If you wanna be 100% sure it'll survive a crash or something, you'd have to save it to a file of sorts
lyric briar
I see
I am writing a plugin about magic, they will use a wand (i.e. a stick) to switch between the magic mode (where the hotbar is full of spells) and the normal mode (minecraft items)
I don't to lose information about the normal mode
otherwise they would kill me
but thanks anyway

I'm sure I'd have something better, sadly I haven't had a reason to do that myself 😅

use https://gist.github.com/graywolf336/8153678 and store the resulting String to the players PDC. Clear it when you reset the inventory. Then you can easily check at login if there is data stored.
vagrant stratus
There's the better answer 😂

Hahaha, thank you Elgar!
eternal oxide
you could even strip it down to not bother with Base64 and just store the Bytes
lyric briar
Thats perfect!
Thank you so much
just one question
when I convert it to base64
does it save the lore
or just the item?
eternal oxide
Just be sure you call Player.save when you add or remove data to the PDC.
lyric briar
I mean, the metadata
eternal oxide
it saves everything
lyric briar
perfect, thank you!
blazing scarab
use <https://gist.github.com/graywolf336/8153678> and store the resulting String...

Hi all. I have a row of problems with my changing inventory.

in the scenarios:
- only ur plugin in the server, and you are testing it
- big server with like 20 plugins

- reload is ok ig
- just restart man
eternal oxide
It depends on how competent you are with OOP. Wether you designed your plugin to handle a reload

idk y
now i only use it in small amounts for being able to get a class' instance
and like util methods
keen kelp
am I dumb or is ```java
public void PublicMethodInMain()

}
cause if yes then I have no idea why I can't refrence it
eternal oxide
no
It all depends on how you are obtaining yoru reference to main
if you are using a static reference Main then no.
if you are using an instance, then yes
keen kelp
ok so what am I suppose to do if I want to call this method
eternal oxide
you pass a reference of your Main to whatever class needs it
keen kelp
like
package.name.main.PublicMethodInMain()
?
eternal oxide
no
Its called Dependency Injection. You often use it for command classes and event listeners.
keen kelp
main main = new main();//?
eternal oxide
Non DI listener = new MyEventClass(); With DI listener = new MyEventClass(this);
That is using DI to pass a reference of the current class to your listener
via its constructor
keen kelp
would that not create a new instance of main?
eternal oxide
using this? no
if you did new Main() it would, and your plugin woudl fail to load.

Its really simple and I already explained it to you
its something you REALLY need to understand to work with Java
keen kelp
ok

Do you know what a class constructor is?
eternal oxide
You don;t

How can I spawn CLOUD particle without the particle being "explode"?
keen kelp
for some reason I feel like DI isn't what Im looking for
eternal oxide
You are trying to access a method that exists in your Main from inside another class. DI is what you need
keen kelp
ok cool

Can i set the contents of an inventory whilst some1 is using it?

Can i set the contents of an inventory whilst some1 is using it?
yes
set contents, then inventory.update()

How do inventories work with crafting tables
they aren't linked to the block are they
summer scroll
I'm trying to spawn a particle that stays in place, but when I spawn it the particle "explodes"
player.spawnParticle(Particle.CLOUD, location, 1);
they are just random inventories
eternal oxide
How do inventories work with crafting tables
a WORK_BENCH Inventory is teh 3x3 crafting
opal juniper
a WORK_BENCH Inventory is teh 3x3 crafting
Yeah, but the inventory it opens has no relation to the actual crafting bench?
eternal oxide
I'm trying to spawn a particle that stays in place, but when I spawn it the part...
try one of the campfire particles
keen kelp
summer scroll
Alright, I'll try it.
eternal oxide
https://paste.md-5.net/sosuhupawu.java
ok, thats a basic class. It has no constructor and you create an instance of it by new AntiNaturalRegen()
keen kelp
https://paste.md-5.net/sosuhupawu.java
yes
eternal oxide
If you wanted to pass a reference of your Main to it, you would add a constructor like so... https://paste.md-5.net/luyewepexi.java
and you would instance it like so new AntiNaturalRegen(this)
summer scroll
try one of the campfire particles
Doesn't work, and it's giving me weird behavior, like the smoke will stays on the block.

Different particles have different animations. Depending on how you spawn it can affect where it spawns and moves
The spawn events are odd. Sometimes the values are locations, sometimes areas

Field modifiersField = Field.class.getDeclaredField("modifiers");
modifiersField.setAccessible(true);
modifiersField.setInt(reflectedField, reflectedField.getModifiers() & ~Modifier.FINAL);
In java 16 I get java.lang.NoSuchFieldException: modifiers
eternal oxide
yes
Adding the constructor like that and passing it a reference to your Main is called Dependency Injection. Passing references between classes
summer scroll
I want it to spawn exactly like this
eternal oxide
```java
Field modifiersField = Field.class.getDeclaredField("modifiers");

I'm pretty sure NNYa explained that yesterady. Thats impossible to do with current Java.
maiden briar
Yes, I have to find another way. I didn't know where the exception came from but now I know
eternal oxide
and the thing has to be same name?
name as in main? or the name of the constructor? main can be anythgin you like
eternal oxide
I know since main is just the "variable" name
you can do anythign like https://paste.md-5.net/odidajoquv.java
eternal oxide
I meant public "AntiNaturalRegen"
Yes, thats the constructor. Has to have the same name as the class
keen kelp
main screw wine it keep trying to open links instead of firefox
eternal oxide
What you pass to the constructor is DI. You can even have multiple Constructors which accept multiple references.
keen kelp
I saw this when I was trying to do the custom damage thing in the bukkit sauce code
I was confused as to what it was doing
this cleared up a lot thanks
eternal oxide
If a Class has no constructor you create an instance by new YourClass(). When it has a Constructor you can only instance it by matching the constructor signature.
So in your example you will only be able to create an instance of that Class by passing Main.
eternal oxide
it will expect you to put this inside its constructor
registerEvents(new AntiNaturalRegen(this), this)
or the other way around, I forget if the register takes plugin first or second
Second I think
keen kelp
it's the other way round
eternal oxide
fixed
eternal oxide
Main is your class name. main is a Field name
keen kelp
it says "this" is main but it expects Main
eternal oxide
this is a keyword that simply means this class instance
You are registering your events in your Main class?
keen kelp
yes?
eternal oxide
then this is correct
keen kelp
but it says required type is Main but provided is main
eternal oxide
Show me what you mean
keen kelp
public AntiNaturalRegen(Main main)
{
this.main = main;
}
this in the AntiNaturalRegen class
eternal oxide
Have you imported Main?
keen kelp
this is in main
getServer().getPluginManager().registerEvents(new AntiNaturalRegen(this),this);
and here
the "this" in (new AntiNaturalRegen(this)
is underlined
eternal oxide
Import Main to your Anti class
keen kelp
I see the problem
the code you gave me had the variable main as type "Main"
but since my main is "main" no capitcal M
it imported some other class
so the type was different
eternal oxide
oh, rename that. ALL class should be capitolized
keen kelp
public AntiNaturalRegen(Main main)
{
this.main = main;
}
just had to change this to (main main) and the variable
oh
eternal oxide
only package names, methods and fields should be camel case
keen kelp
Is it like an organization thing?
eternal oxide
Yep, coding standards
opaque mango
it's basically part of the java language specification's strategy to minimize name hiding
keen kelp
Intresting
opaque mango
*obscuring, not hiding
keen kelp
I have capitalized all my classes but for some reason past me just thought all lower case main is how it's suppose to be
eternal oxide
Standards vary by language
keen kelp
I learned java as my first language but since I didn't know what to do, i abandoned it for like 3 years and was pushed to learn C++
and recently came back because I want to make plugins
so a lot of basic knowledge was lost
I really should re-read all the books

player.spawnParticle(Particle.CLOUD, finalLocation, 5);
Is there a generic Event for a player moving an item between or in an inventory
eternal oxide
```java

Does your location have a direction?
summer scroll
Does your location have a direction?
I'm not sure, basically I spawn the particle on break event.
And get the location from the block.
eternal oxide
The "cloud" particle is normally After jumping into water while on fire in Bedrock Edition or an entity dies in Java Edition.
I bleieve it has a random trajectory set in teh particle
summer scroll
So I need somehow set the trajectory?
eternal oxide
You probably need to use a different particle
opal juniper
well.... its not what i asked 🤷
eternal oxide
So I need somehow set the trajectory?
try the poof particle
summer scroll
try the poof particle
Poof particle? which one, can't find it.
So there is no way to make the cloud particle stays in place?

:
@EventHandler
public void onItemMove(InventoryEvent event) {

Is it cause it is just the base class?
summer scroll
try using <https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.htm...
What should I put on the offset?
eternal oxide
zero
summer scroll
I already tried that.
And same thing.
player.spawnParticle(Particle.CLOUD, finalLocation, 5, 0, 0, 0);
not yet, i don't see that on the javadocs
it works lmao
by adding one more 0
thanks Elgar
summer scroll
and the last is the data, idk what that is
eternal oxide
extra - the extra data for this particle, depends on the particle used (normally speed)
high gulch
is there any worldedit plugin
summer scroll
randomness means like the particle would spread?

Is there a thing inside spigot to remove the spawn protection ?(i wanna do it inside my plugin)
eternal night
Nothing official I am afraid, you would have to use reflection to modify the value
tribal holly
huuu
eternal night
Yes but that isn't inside the plugin code
tribal holly
i don't wanna the user to change it by it self
i wanna pre-configur the server with the plugin
eternal night
it is not tho xD
tribal holly
what ??
eternal night
while not changing the file, they could very much modify the value in the nms.DedicatedServer
what prevents them from just modifying the variable the value is stored in once their plugin starts ?
am I missing something
smart
tribal holly
this is not an event from spigot
eternal night
no, no it isn't. There is nothing in the official spigot-api that allows you to do this
quaint mantle
hi guys, so I'm using Eclipse and I'm not able to implement ParticleLib with Maven into my project. Idk why when I try to compile it doesn't compile the ParticleLib into it...
eternal night
you will either have to a) modify the server.properties file and ask the server owner to restart or b) modify the variable the spawn-protection value is loaded into
eternal night
what boolean xD
tribal holly
canBuild
eternal night
oh, that value is calculated. Have you ever worked with reflection and the net.minecraft.server code ?

oooof

I think you are better off modifying the server.properties file from your plugin then
tribal holly
okay thx

can someone help me with this then please?

did you configure the maven-shade-plugin ?
quaint mantle
idk, what's that?

the maven plugin you need to actually compile/shade your dependencies into your jar

I have a Custom Inventory that i make when a player opens a crafting table. I am using this:
private Inventory inventoryMaker(InventoryHolder holder, Location location){
Inventory inventory = Bukkit.createInventory( holder, InventoryType.WORKBENCH,"G");
ItemStack[] contents = new ItemStack[10];
contents[0] = null;
for(int i = 1; i <= 9; i++) contents[i] = this.plugin.getItemFromTag(Objects.requireNonNull(location).getBlock(), "Slot"+i);
// ^^ Using RedLib to get contents from persistant block data
inventory.setContents(contents);
return inventory;
}
Which works, however i feel there is a problem with the holder as when i then try to get the block from the inventory it hucks a nullPointerError.
I am calling it like this:
event.getPlayer().openInventory(this.inventoryMaker(inventory.getHolder(), inventory.getLocation()));
But if i was to do this:
@EventHandler
public void onClose(InventoryCloseEvent event) {
event.getInventory().getLocation().getBlock();
}
It throws the null pointer on the getBlock()
wraith rapids
are you sure it throws it on the getBlock specifically
sleek dragon
how would I detect if a player clicked on one of the 4 crafting slots in their inventory? SlotType.CRAFTING seems to be for a crafting table only, and I don't know think InventoryClickEvent is called.
opal juniper
are you sure it throws it on the *getBlock* specifically
yeah
i removed it and it worked fine
wraith rapids
i suppose the inventory returns null as its location then
sleek dragon
couldn't you save the location/block when they first access it?
opal juniper
couldn't you save the location/block when they first access it?
To what?
And then what would i use as an identifier
sleek dragon
you're trying to get the crafting table block they right clicked right
opal juniper
Not really
wraith rapids
what are you even doing anyway
quaint mantle
you seem to also be missing your spigot-api ? xD
that's weird but the plugin works
....
opal juniper
So i am making a crafting table that has persistent item storage, however now i need it to work for multiple people at the same time. Because the crafting table inv is not a common one i am making a new inv and showing it to the player when they interact instead of the default one
This is the working example
wraith rapids
and the issue is
sleek dragon
meaning if I leave an item in the crafting table someone will be able to see it in the grid when they open it?
opal juniper
yeah
but if two players open the same one, it dupes the items
because i am just adding them to the inv
wraith rapids
instantiate a single inventory per block
opal juniper
Yeah, thats the idea
wraith rapids
and let the inventory handle maintaining its state over multiple viewers
Block -> Inventory map
populate the inventories on chunk load or whatever
opal juniper
oh, hmm
wraith rapids
or alternatively when the blocks are first clicked
eternal oxide
populate the inventory on access
wraith rapids
depends on how you're populating them
opal juniper
anyone know what this means tho
wraith rapids
doing it on chunk load may be more performant
sleek dragon
world gen issue?
sleek pond
anyone know what this means tho
corrupted something
opal juniper
yeah
sleek pond
i would guess either world or server jar
eternal oxide
even if you load the inventory from file (individually) the momentary lag of it populating will not be noticeable to the player.
opal juniper
its the server jar
wraith rapids
yeah, but having to check said file on every right click of every crafting table is noticeable to the server admin
eternal oxide
cached
wraith rapids
again depends on how you're populating it
opal juniper
I am using RedLib for it
wraith rapids
i don't know how performant red's txt lib is
opal juniper
It seems pretty amazing tbh but i haven't done any testing
wraith rapids
assuming it's just a Block -> data map too, it should be fine to do it on access
if it's slower, you'd want to load it in bulk on chunk load
opal juniper
what idk tho is why i am getting this error
wraith rapids
your jar is missing a class or the classloader is fucked
wraith rapids
what error are you talking about then
opal juniper

something is null
opal juniper
why the block is null
wraith rapids
the block isn't null
the location is null
the inventory you created doesn't have a location associated with it
wraith rapids
location.getblock never returns null
even if the block would be outside of the world
sleek dragon
lol thats why i was confused
opal juniper
But i thought that if you gave the inv the InventoryHolder it transferred data like that
sleek dragon
just store it when you first open it
wraith rapids
depends on the inventory; the workbench inventory probably doesn't
eternal oxide
Don;t create an Inventory, get it from teh Block. If you create a WORK_BENCH it will not work correctly as a crafting table.
wraith rapids
get the information directly from the holder I suppose
keen kelp
Guys so here is my config.yml, I've got all the create file and stuff done, but how do I load it in as a string array?

eternal oxide
```yaml
excluded-worlds:

thats a StringLIst

keen kelp
oh
wraith rapids
pretty sure the workbench inventory works even if you simply create it
eternal oxide

opal juniper
pretty sure the workbench inventory works even if you simply create it
no it doesn't
keen kelp
ok thanks
opal juniper
i just tried it
wraith rapids
well then you're kind of fucked
eternal oxide
the whole process is clientside
I'm not sure it gets linked to recipies
eternal night
valid
eternal oxide
I know furnaces won;t work like that, but I'm suspicious of crafting too
wraith rapids
does it create a new instance of the inventory for each player in under the hood then
opal juniper
does it create a new instance of the inventory for each player in under the hood...
yeah
eternal oxide
It might
keen kelp
config.getStringList("excluded-worlds")
and stringlist have .getstrings to convert to a string[] iirc?
wraith rapids
next thing to be uncertain of is how the clearing slots mechanic works
eternal oxide
No it returns a List<String>
wraith rapids
since normally, when a player closes the inventory, the slots are cleared
tribal holly
i take the spoon feed thx
opal juniper
since normally, when a player closes the inventory, the slots are cleared
yeah, atm i store the items in a blockdata hash
wraith rapids
the question is whether that happens when the last player viewing it has closed the inventory
or whather it happens when any player closes it
eternal oxide
Items shoudl drop to teh floor
eternal night
actually, wouldn't recommend xD
that field is final
jigsaw is gonna come for you
keen kelp
No it returns a List<String>
oh so like dynamic size right
eternal oxide
?paste
queen dragonBOT
wraith rapids
if it happens when any player closes it, you're kind of fucked, I don't see a reliable way of maintaining inventory state without flicker or jitter if that is the case
if it happens only once the last viewer closes it, you should be fine
opal juniper
the problem is that when a player closes the inventory i have it to clear the inv
wraith rapids
y
opal juniper
cause if not the items ended in the players inv
wraith rapids
in that case you're extra fucked
opal juniper
thats what i mean, sorry
eternal oxide
A workbench that returns items to the player (example) https://paste.md-5.net/apenoyizah.java
wraith rapids
i suppose the best you could do, then, is to have a separate inventory for each viewing player, and when any player mutates the contents of their inventory, reflect the changes in all of the other currently open inventories
kind of expensive, and going to result in some jitter, but based on what you've said I don't see any other way around it
opal juniper
i suppose the best you could do, then, is to have a separate inventory for each ...
thats what i was trying to do earlier
but i couldn't find a good event for the moving items
wraith rapids

you'll have to do some of the calculations of where stuff ends up at yourself for shift clicks

and a few others
sleek dragon
on the subject of crafting
how would I detect if a player clicked on one of the 4 crafting slots in their inventory? SlotType.CRAFTING seems to be for a crafting table only, and I don't know think InventoryClickEvent is called.
wraith rapids
i don't remember how the inventory crafting table works
a lot of stuff about the player's inventory is clientside
but going by common sense clicking those slots should still fire events
keen kelp
is there an event for player disconnecting
wraith rapids
eternal oxide
I just tested and a WORK_BENCH inventory thats not backed by an actual crafting table knows no recipes.
opal juniper
does the InventoryClickEvent fire late enough that i can do inventory.getContents() ?
wraith rapids
it fires before anything is actually modified iirc

What are some good items I could use for a back/forward in a paged inventory? I currently just use different shades of blue glass planes.

glass panes are generally fine
can always texture them to be actual arrows with a resourcepack

how do I store yml files in a folder within the plugin's folder if that makes any sense
lusty cipher
JavaPlugin#saveResouce and JavaPlugin#getResource @keen kelp
keen kelp
no I mean like a
eternal oxide
The File you create points to teh location
keen kelp
subfolder
wraith rapids
create a folder
lusty cipher
well just put the files into src/main/resources/subfolder
wraith rapids
then put the files in it
eternal oxide
just be sure to save your config using plugin.saveDefaultConfig() in your onEnable to be certain your plugin directory has been created
wraith rapids
there is no good way to extract an entire directory out of the jar though I don't think
eternal oxide
He's not on about resource files
wraith rapids
whot
keen kelp
No Im trying to do a player storage thing
wraith rapids
just create a directory
eternal oxide
Do as I just said
lusty cipher
he wants to store into plugins/YourPlugin/subfolder (for example)?
wraith rapids
it's not rocket science
keen kelp
yes
eternal oxide
when you followed that Tutorial earlier it would have had you create a File. new File( plugin.getDataFolder(), "filename.yml")
keen kelp
yeah?
opal juniper
How can you compare two ItemStack[]
eternal oxide
That defines where the file goes and what its name is
so when you have your fc you can fc.save(file)
keen kelp
how do I tell it to go into a subdirectory though
eternal oxide
you want it in a folder under your plugin folder?
keen kelp
yes
lusty cipher
How can you compare two ItemStack[]
ItemStack#equals
keen kelp
I was thinking each player has their own storage with the file name being their UUID
eternal oxide
File file = new File( plugin.getDataFolder() + SystemProperty("File.separator") + "subfolder", "filename.yml");
file.mkdir();```Arrays.equals
sleek dragon
cant seem to cancel a player putting an item into their crafting grid but I can cancel them taking something out of it
eternal oxide
however you will then have to call file.mkdir()
wraith rapids
File.separator btw :fingerguns:
eternal oxide
yeah, he can google that part 🙂
