@young knoll Im pulling my hair out. Doesnt matter what i try, my work directory refuses to include moj mapped files for this class.

Modify the outgoing ping response packet
Everything that maps from X to Y should have a dedicated class which handles this relation.
And managers are a simple solution for that.

Try the damage event

Yes, the damage event returns an ENTITY_EXPLOSION I believe and there is knockback and damage, but no particles or block damage
also I don't want to cancel out ENTITY_EXPLOSION and even if I did, I also don't want the knockback. At this point, the only really viable solution is to go back in time and remove the skull
worthy yarrow
i know it can be done somehow
If I had to guess, it has to do with packets, intercept the sound packet from damage entity event or something and just don’t send it to the player

What version?
tranquil badger
What version?
Latest
echo basalt
Then it's pretty simple
You don't need data watchers
Although it'd be nice to have entity data
In short, every nms Entity has a "DataWatcher" (whose name is actually SynchedEntityData)
It contains a few fields, which have explicit types and default values
And each entity class (and its parents) define fields
For example the field 0 is of type byte and it's just a bitmask for visibility, glowing etc
Before 1.19 you had to create a whole data watcher (For packet entities this was done by just creating a new entity, assigning values and getting the data watcher) as the packet needed it
After 1.19 it's just a List of data values
If you're using ProtocolLib, it's a List<WrappedDataValue>
These data values are basically just a class that contains
- Their ID (int)
- Their Serializer (basically data type)
- Their value
For ProtocolLib, creating such list is quite trivial:
List<WrappedDataValue> list = List.of(
new WrappedDataValue<>(0, Serializer.Registry.get(Byte.class), (byte) 0x40)
)
With NMS you just get the entity's SynchedEntityData and call either packDirty (Returns a list of every value that has changed since the last packDirty call) or getNonDefaultValues (self explanatory)
That's about it
tranquil badger
I'm not using protocolLib, it asks to pass a datawatcher, how would I use that wrappeddatavalue instead
tranquil badger
Let me get to PC

I work on multiple devices and don‘t want to redownload the server every time. I basically have the eula, the server jar and some start scripts on my repo.

I just want to know if it‘s only the spigot.jar that‘s not to be destributed. Bc then i‘ll have to .gitignore it once i release the plugin.

How would i use it to display a constant actionbar (like in hypixel skyblock)?
remote swallow
use a scheduler or something to send a new action bar every tick or a few ticks

How would i update it tho?
I would create a Buffer. So a String for each player. Then send this buffer every 2 seconds, and when it updates.
So your task just sends whatever is in the buffer, and when the content changes, then you immediately send this update.
There are a few more optimizations you could do, but this should be enough.

Can you provide an example pls? Sry im new to this

Do you guys know how to get locations of corners from blockdisplay
That is quite tricky, depending on what transformation you applied to the display.
eternal oxide
it should still have a bounding box
lost matrix
Can you provide an example pls? Sry im new to this
Start by writing a manager class which keeps track of your buffers. Let it contain a Map<UUID, String> to keep it simple.
It should map players UUID to their buffered String.
Make sure to make the Map private and final, and dont have a getter or setter for it.
Just methods like
public void addPlayer(UUID playerId)
public void removePlayer(UUID playerId)
public void updatePlayer(UUID playerId, String content)
public void sendBuffer(UUID playerId)
lost matrix

The AABB of block displays is infinitely small iirc
eternal oxide
I thought it would be all encompasing, even though it has no collision
coarse trout
doesnt work
young knoll
Nah the bounding box is size 0
For all 3 display entities
You’d have to create a base vector for each corner and then apply the transformations to them
coarse trout
now i got public List<Location> getBlockCorners(Location location) {
List<Location> corners = new ArrayList<>();
// First
corners.add(location);
// Second
corners.add(location.clone().add(location.getDirection().clone().multiply(1)));
return corners;
}

Again, we need to know what transformations you applied. Otherwise this only works for a very specific case.
coarse trout
i dont know what are talking about but
BlockDisplay blockDisplay = location.getWorld().spawn(location, BlockDisplay.class);
blockDisplay.setBlock(Material.WHITE_WOOL.createBlockData());
lost matrix
Alright so no transformations at all. In that case just get the Location, add (1, 1, 1) to it and span a BoundingBox on those two vectors.
This will give your the corners of your display.
lost matrix
i mean block display can be rotated
And scaled, and translated.
You can literally create a 100x100 stone block if you wanted to

How can I send message to player when he step into dropped block that were dropped from player by plugin? I have created a pee plugin and I need to send message to player when he step into dropped block like. You have step into player's pee.

Why does those logs are scaled smoothly but when it comes to updating their location it is rough?
FluentApi.tasks().taskLater(() ->
{
//Scaling
Transformation transform = display.getTransformation();
transform.getScale().set(0.3f, 0.3f, 0.3f);
display.setTransformation(transform);
}, 20);
FluentApi.tasks().taskTimer(60, (a,b) ->
{
//moving
Transformation transform = display.getTransformation();
transform.getTranslation().add(0.2f, 0, 0);
display.setTransformation(transform);
}).start();
private BlockDisplay createBlockDisplay(Location spawnLoc, Material material) {
BlockDisplay blockDisplay = (BlockDisplay) spawnLoc.getWorld().spawnEntity(spawnLoc, EntityType.BLOCK_DISPLAY);
blockDisplay.setBlock(Material.OAK_LOG.createBlockData());
Vector3f translation = new Vector3f(0, 0, 0);
AxisAngle4f axisAngleRotMat = new AxisAngle4f((float) Math.PI, new Vector3f(0, 1, 0));
Transformation transformation = new Transformation(
translation,
axisAngleRotMat,
new Vector3f(1f, 1f, 1f),
axisAngleRotMat
);
blockDisplay.setInterpolationDuration(25);
blockDisplay.setTransformation(transformation);
blockDisplay.setGlowing(true);
FluentApi.events().onEvent(PluginDisableEvent.class, pluginDisableEvent ->
{
blockDisplay.remove();
});
return blockDisplay;
}
Simplest way would be PlayerMoveEvent and check if the to-location is within this block but the from-location isnt.

Try setting the interpolation before translating as well

IDK, this part is example code from Spigot Forum

Im heading out for a walk now. Try using a teleportation interpolation and teleport the display.
young knoll
You should be setting the entire transformation at once
Otherwise you’ll override any previous interpolation in progress
gleaming grove
to prevent that I've set setInterpolationDuration every 25 ticks and taskTimer every 60 ticks, so it should not override, right?

It’s a funny story or not
They maked me somehow a server jar that run my slimeworldmanager and my spigot
Because they don’t have a functionality for custom startup parameters

id love to know what you are even running
i cant find any of those git hashes in the past few years
oh i think ive found it
all the way back in 2016
so its 1.8.8 that i have a feeling is old old so you should update

1.8.9 does not exist as a server version
1.8.9 is a client only version with protocl compat to 1.8.8 servers

Should i try with 1.8.8?

you are on 1.8.8

1.8.9 does not exist in spigot

I used api for SQL and lamp api and now plugin size is 13mb and I can't upload what should I do
remote swallow
use the libraries feature in plugin.yml for stuff thats on maven central
tender shard
- minimize the .jar (both gradle's shadow and maven shade support that)
if that's not enough: - use plugin.yml "libraries" feature if your stuff is on maven central and you're supporting 1.16.5+ only
otherwise - use libby or sth similar
alternatively just upload your plugin to another site (external download)

Is this application of pdc correct?id recommened to cache the keys, and you can use NamespacedKey.fromString("key:value") to make it easier
but the rest looks fine and a correct use of it
worthy yarrow
flat file prolly fine for that yeah?
remote swallow
by cache the keys i just mean final/static final variable
worthy yarrow
oh thought you meant like save
remote swallow
its easier to create them in 1 place incase you do ever want to change the key in future
worthy yarrow
Gotcha
The level however shouldn't be final correct? as I've got a task that'll increment xp every second, level is decided by: (BASE_XP + XP_INCREMENT) * level
Or rather the increment increase per level is decided that way
remote swallow
the values dont matter, just the key
worthy yarrow
Ah right
I'm dumb
private static final String chickenPetKey = "chicken_pet_key";
private static final String chickenLevelKey = "chicken_pet_level_key";
...
@Override
public ItemStack petItem(){
NamespacedKey chickenKey = new NamespacedKey(CoolPets.getPlugin(CoolPets.class), chickenPetKey);
NamespacedKey levelKey = new NamespacedKey(CoolPets.getPlugin(CoolPets.class), chickenLevelKey);
ItemStack chickenPet = new ItemStack(Material.CHICKEN_SPAWN_EGG);
ItemMeta chickenPetMeta = chickenPet.getItemMeta();
chickenPetMeta.getPersistentDataContainer().set(chickenKey, PersistentDataType.STRING, getPetId().toString());
chickenPetMeta.getPersistentDataContainer().set(levelKey, PersistentDataType.INTEGER, getPetLevel());
chickenPet.setItemMeta(chickenPetMeta);
return chickenPet;
}```
Look fine?The naming could prolly be better, but if it looks fine that's the goal
tender shard
why not just store the NamespacedKey?
public static final NamespacedKey CHICKEN_PET_KEY = NamespacedKey.fromString("myplugin:chicken_pet");
Well I thought that too, ig this is just easier
But also it might have been implied and I missed it
Is there a reason you did "myplugin:chicken_pet"?
tender shard
you can either do "namespace:key_name" (first method) or just use "key_name" and provide the plugin instance (second method)
doesn't really matter
i prefer first one because then you don't need any instance and can just use static final fields without having to dependency inject anything or getting the instance somewhere else
worthy yarrow
private static final NamespacedKey chickenPetKey = NamespacedKey.fromString("CoolPets:chicken_pet_key");
So this is fine?
worthy yarrow

hey there, i'm having problem with getPersistentDataContainer method. Basically my ide (Intellij) tells me that this method does not exist for player or itemMeta and refuses to compile the plugin... how can i fix it? i tried changin spigotAPI version in maven file but that didn't really get me anywhere...
this is the code:
public static void WritePlayerPDC(Player player, String key, PersistentDataType type, Object value){
NamespacedKey nKey = new NamespacedKey(MineconomiaCore.getPlugin(MineconomiaCore.class), key);
PersistentDataContainer pdc = player.getPersistentDataContainer();
pdc.set(nKey, type, value);
}

import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.persistence.PersistentDataContainer;

why is vaultapi even importing spigotapi in the first place?
ancient plank
just vault things
tender shard
why is vaultapi even importing spigotapi in the first place?
it's a transitive dependency. it's just how maven works. you have two options:
- Move spigot-api up yuorself (as you did)
or - Tell maven that you only need vault, but no transitive dependencies of it (since nobody would use vault without adding spigot-api themselves to pom)
(either using a filter, or simply using <excludes> inside vault's <dependency>
but if you think about it, it only makes sense that adding vault also adds spigot as dependency, how else would you be ever able to use Vault in your project otherwise?
vault could ofc also declare spigot-api to be an <optional> dependency, that'd probably be the best solution
