check if it contains air

check if it contains the item ur trying to give to them and if its not full
and if both are false drop it on their body

Thats how i would approach it:
private void giveAmount(Player p, ItemStack is, int amount) {
is = is.clone();
is.setAmount(amount);
World world = p.getWorld();
p.getInventory().addItem(is).values().stream()
.filter(overflownItem -> !overflownItem.getType().isAir())
.forEach(overflownItem -> world.dropItemNaturally(p.getLocation(), overflownItem));
}
Look at the filter. There are several types of air now.
harsh totem
I don't think I need to do this.
If some items are not given the enter the hashMap and then it uses the for loop to drop the items in the hashMap at the player

So you need to use Material#isAir to be sure.

Add this to your stream:

Add a safeguard at the top of your method:

World world = p.getWorld();

This enforces the constraints of the method.

Hey guys, so i'm using a quite funky system for the chat, it relays messages from discord to players, relay player messages from a server to another (of the bungeecord network) with some funky pluginmessaging kind of feature, etcetera...
Anyway, what is sure is that there ain't no proper "chat", the message is caught, cancelled, formatted, and rebroadcasted. (not directly formatted for some difficult to explain reasons)
Whether this is a bad design and should be rewritten is not the purpose of my question though, I am just wondering if it will still work in 1.19, because i've been hearing they are completely changing the chat, and that the player messages have to be intercepted by their server first???
I'm a bit confused honestly by what is really going to be affected in the chat, but can I be relieved that despite all the weird implementations I've mentioned, it will still work?
misty current
if you are referring to the new chat encryption that is coming out, it will be fine because messages are decrypted on the server end, of course
vivid cave
ok so sole change, messages are just going through an encryption process but nth changes server side?
lost matrix
The whole packet communication between client and server is currently encrypted using AES anyways.
You wont feel a change unless you fiddle with raw packets before the decryption happens. And nobody does that really.

yea, unless you want to MIDM lol

Bad news: You cant extract the value without damaging the entity in the first place.
The best i could find is the method:
EntityDamageEvent handleLivingEntityDamageEvent(Entity damagee, DamageSource source, double rawDamage, double hardHatModifier, double blockingModifier, double armorModifier, double resistanceModifier, double magicModifier, double absorptionModifier, Function<Double, Double> hardHat, Function<Double, Double> blocking, Function<Double, Double> armor, Function<Double, Double> resistance, Function<Double, Double> magic, Function<Double, Double> absorption)
In CraftEventFactory. But you would have to copy/paste a ton of stuff from LivingEntity#hurt(DamageSource source, float amount) in order to call this event.
I mean if you want to take one or two days then you could probably skim this method and recalculate the damage that would have been dealt. But this is only true
for this exact version then.
misty current
that's a lot of parameters
it is pretty weird that they require you to add all this stuff when you could most probably get them from the entity itself(like absorption hearts, potion effects)
don't feel like its worth it tho, also i'll probably do some custom damage stuff so unsure if i'll need it at all
but useful to know, thanks

So first of all:
Bukkit.getMessenger().registerOutgoingPluginChannel(MY INSTANCE, "BungeeCord");
This should be called once in the onEnable.
Ok. Now the first utf input from a BungeeCord message is always the sub-channel.
So your servername variable contains "GetServer" every time you receive the server message.
ByteArrayDataInput in = ByteStreams.newDataInput(message);
String subChannel= in.readUTF();
if(subChannel.equals("GetServer") {
String serverName = in.readUTF();
System.out.println(serverName );
}
When you read something from an ByteArrayDataInput, the byte pointer moves further into the message.
So every time you read something, you get the next message.
Example:
[0, 3, 3, 9, 2, 4]
|
readByte -> reads '4'
[0, 3, 3, 9, 2, 4]
|
readByte -> reads '2'
[0, 3, 3, 9, 2, 4]
|
readByte -> reads '9'
And so on.
sage merlin
how do i create a java project with nothing in it no api no nothing just plain java
lost matrix
For your output:
You can only send to one single sub-channel when you send a message.
For example "GetServers"
out.writeUTF("GetServers");
And after that you need to send the message because there are no expected arguments.
So the Proxy receives "GetServer" and responds with a list of all servers.
This can then be read in the listener using:
ByteArrayDataInput in = ByteStreams.newDataInput(message);
String subChannel= in.readUTF();
if(subChannel.equals("GetServers") {
String[] serverList = in.readUTF().split(", ");
System.out.println(Arrays.toString(serverList));

You are getting into the realm where writing a BungeeCord plugin might be the better approach.
Then you can define custom channels, messages and responses.
2 different plugins. One is installed on bungeecord and one is installed on spigot.
Then those two communicate via the messaging channel.
You can also compile one jar that can be deployed on both types of servers.

it happens when I have like 4 people in the server as well even when its not very overloaded
I have no idea why tho
dusk flicker
yep Paper has an armor update event

this ones worked good for me.

I would recommend either use Paper's event, or that lib Epic sent
Rather than running that check that fast (Which you really wouldent need to do it that fast, 20 times a second would probably still be sufficient)

50 times per seconds was from 50players each second

This is odd to me as I haven't had this issue before. I just tested your exact code and it gave me the same results. My best guess is that it's grabbing the default option from the internal config that's included with the jar, but I'm unsure as to why.

for some reason Build Artifacts doesn't make a plugin jar for me. why is that?

Because the config now looks like this, but is reading from the internal jar.

why does it say unloaded world: avalon as well even when my newWorld is avalon
and it doesnt even unload them

for some reason `Build Artifacts` doesn't make a plugin jar for me. why is that?
You need to set up an artifact first, go to project structure, artifacts, click the plus sign in the top left and select JAR from modules with dependencies
ivory sleet
gradle isnt supposed to work with artifacts
frail sluice
oh. that makes sense.
is there any alternative? it would be really helpful to have the jar directly in the plugins folder
ivory sleet
yeah
frail sluice
may I know what is it?

Is there also a way to do that with maven?

This would be my primitive approach:
https://gist.github.com/FlorianMineCrypto/109771d6b1906cc8788e012b792f652a
Creating a ItemSet item is as simple as:
ItemStack bardHelmet = new ItemStack(Material.GOLDEN_HELMET);
ItemSetHandler.markItemAsSetItem(bardHelmet, ItemSetType.BARD);
And checking for a type is as simple as:
ItemSetType setType = ItemSetHandler.getFullSetType(player);
Because for maven they say you don't want to change output dir. Right now I just run an artifact as well as maven on build to copy
frail sluice
https://www.spigotmc.org/wiki/build-you-spigot-plugin-with-gradle-groovy/

So, doing it manually seems to work. Not sure why it grabs the internal file instead of the one from disk to be cached, but if you do it this way, then you shouldn't have that issue.
I'm not sure where the disconnect is, as this is what those methods do internally.

how do I add a dependency from mavenCentral to my plugin? just adding it to the build.gradle doesn't work for me
crisp steeple
mavenCentral()
frail sluice
yea, obviously. but it doesn't add it to the jar

idk then, i dont usually use gradle

So I had a question
I am coding something that makes it so that certain players have certain items
So for example, let's day Bob has a special hoe
What I want to be able to is like /hoeholder
And then it would show who has it, even if they are online
kind hatch
Loop through every player, check if their inventory contains the hoe and return the players that do.

After unloading the world you need to wait a second or so until everything is written to disk.
You can also constantly check if the file has any filehandles open.

I am trying to send a request to some external API but I get IllegalStateException: zip file closed. I believe its related to URL caching? how can I fix that?
eternal oxide
disable AI if it has any or disable gravity
midnight shore
you could teleport it to the spawn when it spawns so you'll disable every offset
eternal oxide
are you actually spawning it or dropping it?
dropping has a random element
spawning doesn't
using this you can spawn it and copy any meta/data to it in the Consumer https://hub.spigotmc.org/javadocs/spigot/org/bukkit/RegionAccessor.html#spawn(org.bukkit.Location,java.lang.Class,org.bukkit.util.Consumer)

To prevent embeds.

Restart, don't reload
frail sluice
every single time? while developing?
eternal oxide
yes, unless you are specifically testing reload
frail sluice
world loading takes up some time though
it'll make developing workflow much inefficient
lost matrix
You can optimize it down to 20-30ms if you have an nvme
eternal oxide
do you get the error when doing a fresh start?
waxen plinth
every single time? while developing?
It doesn't have to be every single time
Reloads can save you lots of time in testing
But the error you're showing is the result of a reload
It happens sometimes

Hi, how can i disable the render of the off-hand item for other players? i know i'll have to use packets but could someone help me with them?
crisp steeple
it depends, if you're going to use 2 completely seperate plugins on one server you would probably have to use plugin messages to communicate with them, another approach would just be to merge them together and make an api for accessing them both simultaneously
did you make this BanManager?
if so, you could use plugin messages
or make an api for it like zacken said
radiant cedar
does having every world created when server is enabled a bad idea
radiant cedar
but does it change ram usage
after they are all created
or does that just depend on if they are loaded or not
left swift
redis pubsub should be running on a separate thread either way
pubsub yes, but ComplementableFuture#get probably no, but it has timeout (4 sec in my case), so I'm asking if should I use separated thread for the get method.

pass the instance of your main class into wherever you're trying to use it
granite owl
pass the instance of your main class into wherever you're trying to use it
thats what i did before
public static void registerRecipes(main plugin)
{}
crisp steeple
so why did you change it then?
granite owl
my main class only contains the bukkit callbacks themselves
and then passes the vars to the actual functions
crisp steeple
what
granite owl
like this
public void onEnable()
{
Bukkit.getServer().getPluginManager().registerEvents(this, this);
Items.registerRecipes(this);
}
yes but you should try to avoid static abuse

do I need to do a scheduler to delay it ?

dont make static listeners

in this case i think it is
granite owl
almost all take manipulation in
crisp steeple
some are sure, but it just depends on the event
granite owl
whether its to cancel the event
or to relocate its destination
@trail oriole ur answer
sure
crisp steeple
do not use static listeners 🙃
trail oriole
agreed
crisp steeple
bruh what is User
crisp steeple
lol
granite owl
gl guys last time i didnt use a static context to outsource the events and wrote everything in the event method itself, it got too messy
you can write thousands of different functionalities into one and the same function
i wont
granite owl
but creating instances of functions that have only one purpose isnt?
crisp steeple
"User" seems like a very good example of a class that definitely should not be static
you would want instances of each individual User
granite owl
also funny that u call me out for passing the event as parameter for certain methods
but i suppose you are aware that u dont pass the object
but only a pointer
xD
right?
crisp steeple
of course it can, in this case it definitely is not
granite owl
otherwise i couldnt even cancel the event
crisp steeple
static should never be used as an event handler
