once I reach a knockback of 18, it stops increasing

u know how when u craft a block of honey it leaves the bottles behind quackiee
eternal oxide
the code I sent knocks the player back more each time I hit him
What are you trying to do with it now?
tender shard
where's the problem? you're applying a vector 10|2|-10
that's pretty much
just use a shorter vector
carmine valley
What are you trying to do with it now?
knockback further than 18 blocks
lethal python
mfnalex do u know if this happens
eternal oxide
you want it to go further and it won't?
carmine valley
where's the problem? you're applying a vector 10|2|-10
sorry, I don't understand
carmine valley
you want it to go further and it won't?
yup, it doesn't increase on it's own
eternal oxide
does your multiplier still increase?
carmine valley
the vector is increasing as you see in the console, but the actual kb doesn't
quaint mantle
omg I have been waiting to use this command for a long time
tender shard
sorry, I don't understand
oh you want to do more than 18 blocks? well then use a bigger vector

Here are some links to get you started on learning Java:

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.
quaint mantle
(its a joke dw)
carmine valley
oh you want to do more than 18 blocks? well then use a bigger vector
isn't it supposed to get bigger on it's own?
as I programmed it to do
eternal oxide
you increase your multiplier
carmine valley
mhm
eternal oxide
if you find it is hitting the floor increase your Y
if its only reaching 18 blocks and hitting the floor, you don;t have enough elevation
carmine valley
if you find it is hitting the floor increase your Y
we tried .add(new Vector(0,5,0)) and .setY(2) and still 18 blocks
tender shard
set Y to 100 and see what happens
eternal oxide

carmine valley
aight
tender shard
if you get further than 18 blocks now, it's simply because you hit the ground too soon

quaint mantle
I was finding the code tho D:
eternal oxide
ah k
carmine valley
set Y to 100 and see what happens
it's as if nothing happened
as if it's still .setY(2)
no vertical velocity

how did you spawn your nms entity?

can't we alter this limit with some kind of setter?

how would i use persistent data container

you could look into the source code of CraftPersistentDataContainer or so

kinda stupid that it requires the server tho given that there is only one server
carmine valley
@humble tulip hey dude
humble tulip
yeha
carmine valley
we figured it has to do with the player
because it worked fine on all other entities
humble tulip
oh wow
carmine valley
still trying to figure out how to bypass that
ornate patio
i'm assuming like this though right
CraftEntity craftEntity = CraftEntity.getEntity((CraftServer) Bukkit.getServer(), entity)

only thing I hate is how Spigot internally casts to CraftServer

If you get an ItemStack from Inventory#getContents, and then use ItemStack#setAmount (or ItemStack#setType etc...), is the ItemStack in the Inventory updated, or do you need to overwrite the ItemStack somehow?
echo basalt

I found an event called PlayerVelocityEvent
do you think I can for loop the thing?
carmine valley
nah that would make it happen every time the player walks

causes unexpected crashing tho
I once tried injecting something that wasn't CraftServer
humble tulip
wait why
ivory sleet
yeah

funky command map that didn't fire events on certain conditions
ivory sleet
I mean the api doesn't really support custom implementations unless mentioned otherwise
humble tulip
there's supposed to be one server
ivory sleet
believe its even documented that way
echo basalt
I wrapped CraftServer
but gotta love having everything final
can't even extend it
CraftServer is a final class, with a final command map with final implementations
tardy delta
sounds like fun
ivory sleet
but I mean apis like these are not very friendly towards the open closed principle for instance, they only care about providing the api as is and thats it, no custom implementations or low level detail exposure

is there a method to hit the player? maybe we can do that @humble tulip
echo basalt
do you need the knockback vector or something?
noble spire
you might want to craete a thread for whatever you're working on
brave sparrow
@carmine valley can you explain what youâre attempting to do and what your current solution is to that problem
carmine valley
do you need the knockback vector or something?
I made a knockback plugin, on entitites it keeps increasing like I want it to, on players once it reaches 18 blocks it doesn't knock them any further
carmine valley
can I edit it?
brave sparrow
Are you running an anticheat
echo basalt
but it usually throws a console warning if you go above it
carmine valley
Are you running an anticheat
nope none, flight is on too
echo basalt
just run it on a scheduler and call it a day
brave sparrow
You could theoretically lerp between two points and perform a sequence of small delayed teleports
Lol
carmine valley
the player also didn't experience any vertical velocity even though I tried to do .add(new Vector(0,5,0)) and setY(100) and neither worked
no vertical velocity at all
carmine valley
I tried 2 and 100, same results
humble tulip
He set it at 2 and still notbing
brave sparrow
2 is decently high
carmine valley
what's frustrating is that it works fine on all entities but not players
humble tulip
Oh yeah that's why antikb works
brave sparrow
You can tell the player their new velocity is whatever you want, if the client doesnât like it it isnât gonna happen
carmine valley
then how did I even get to 18 blocks in the first place if it's solely depends on the client
oh ok
brave sparrow
The client decided that was ok
carmine valley
so are you saying I need a custom client?
humble tulip
Or a mod maybe
brave sparrow
No Iâm saying you need to stop trying to do massive vectors at once
eternal oxide
You need to calculate the locations in small steps
brave sparrow
^
carmine valley
what about if we hit the player again? is there a method to do that?
brave sparrow
Lerp between two points
echo basalt
you just add the vector or something
but yeah
smaller steps
that's why my custom shield works :)
carmine valley
wouldn't that look crude with the tp?
eternal oxide
the client will smooth between near locations
brave sparrow
Minecraft treats small teleports as movement
carmine valley
oh you mean very small teleports
brave sparrow
Yes
eternal oxide
every tick
brave sparrow

carmine valley
I've never done anything like that, what would that look like?
echo basalt
uhh
carmine valley
I meant in code
brave sparrow
You need a bukkitrunnable
carmine valley
does the video explain implementation?
echo basalt
no but my code is pretty simple to understnad
tardy delta
its just a custom recipe and a resourcepack x)
carmine valley
but just to make sure, there is no method to hit the player right?
echo basalt
and a scheduler
echo basalt
but just to make sure, there is no method to hit the player right?
LivingEntity#damage(double, LivingEntity)
perhaps
carmine valley
hmmm

so are all servers
you can do a lot with custom recipes and resourcepacks
tardy delta
ye
carmine valley
how about I just damage the player again so he goes further distance?
echo basalt
how about I just damage the player again so he goes further distance?
knockback doesn't occur with that method
carmine valley
in the game I'm trying to make the player's will be always healed to 100%

you can just set a manual knockback
carmine valley
with setVelocity?

I can't find that in the docs

no the error suggests to create a method damage() in my class
why isn't the compiler recognizing the import?
tender shard
obviously you can only use instance methods on an instance of the class that declared that method
tender shard
why isn't the compiler recognizing the import?
my guess is because you don't know basic java and simply tried to do "damage(...)" somewhere instead of using it on an instance of a Damageable

shouldn't it work on a player entity?

Hey guys, I'm trying to make a spigot plugin that increases the player's KB the more they are hit, I've so far constructed the following code. One issue with it is that it stops knocking the player further once the knockback sends you 18 blocks away due to some Player class restriction(All other entities can be hit further than 18 blocks and don't have such a threshold) I've tried fixing it by damaging the player artificially and sending him further away once after 3 hits of reaching the threshold, but it didn't quite work, any ideas why it didn't? and any alternative solutions? code:```cpp
package me.r3dx.mcbrawl;
import org.bukkit.entity.LivingEntity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;
import org.bukkit.util.Vector;
public class Knockback implements Listener {
int heatValue = 0;
@EventHandler
public void onPlayerHitPlayer(EntityDamageByEntityEvent event) {
if (event.getDamager() instanceof Player && event.getEntity() instanceof Player) {
heatValue++;
Vector v = event.getEntity().getLocation().toVector();
event.getEntity().setVelocity(v.subtract(event.getDamager().getLocation().toVector()).normalize().multiply(heatValue));
LivingEntity en = (LivingEntity) event.getEntity();
Vector v2 = en.getLocation().toVector();
if(heatValue >= 8){
en.damage(1);
en.setVelocity(v2.subtract(event.getDamager().getLocation().toVector()).normalize().multiply(heatValue));
}
}
}
}```
Run maven and see what it says

player 1 joins gets the name tag

no

Shouldn't you be doing this?
each player should have their own scoreboard..
their scoreboard display's their stats

Right.. So you need to add all online players to that players scoreboard so that the newly joined player can see their nametag prefix?

should i make a seperate scoreboard to do this?

my computer froze when i ran that code
humble tulip
should i make a seperate scoreboard to do this?
Don't you have to give the new ppayer a scoreboard?

The same way u need to add the newly joined player to currently online player scoreboard
U also need to add currently online players to the newly joined plauers scoreboard

so 2 scoreboards it is
humble tulip
I'm not too well versed on scoreboards
Well doesn't each player have tjeir own scoreboard?

Yep

okay,
humble tulip
@subtle folio is this consistent with what you see ingame?
Cuz this is wjat i think your code does

No, that's checking if there's an entry with that player at all
im really confused what you mean
vocal cloud
You check if they have an entry then loop over all the entries to find the players?
sterile token
im really confused what you mean
Me too lmfao
shadow gazelle
But why? There is no need to check tha
No point in looping through everything if the player isn't in there at all
crisp steeple
.get(event.getPlayer().getUniqueId()) does the same thing as iterating through all of them and checking if its the players
vocal cloud
But why loop through everything when you can just .get?
sterile token
But why loop through everything when you can just .get?
Yeah, he can just do Map#get(path) instead of iterating
ivory sleet
I wondering to keep track of a custom player object, and keep it cached for some...
use a cleanup pattern
shadow gazelle
I was trying to use duplicate keys for whatever reasonđ¤Śââď¸
sterile token
use a cleanup pattern
Allright thanks. Something like Guave or Caffeine one?
ivory sleet
Caffeine is definitively favored to Guava
it might look like the same deal superficially, but the implementation is much more sophisticated and optimized
vocal cloud
Idk man Guava tastes pretty good
ivory sleet
myes, but anyway when I say cleanup pattern I mean that you can have some runnable that clears invalid map entries every minute or so
iirc thats how they do it in luckperms

does PersistentDataContainer work for CraftEntitys?
CraftEntity craftEntity = CraftEntity.getEntity((CraftServer) Bukkit.getServer(), entity);
PersistentDataContainer persistentDataContainer = craftEntity.getPersistentDataContainer();
persistentDataContainer.set(new NamespacedKey(plugin, "hunger"), PersistentDataType.DOUBLE, 0.5);
I'm using this code but it doesn't save any data
i've worked with persistent data containers before and they work fine, but I suspect this may have sometihng to do with CraftEntity..
opal juniper
what are you using craft bukkit entities rather than normal bukkit
ornate patio
custom NMS entities
opal juniper
i imagine that might have something to do with it
but you can cast that to a normal bukkit entity anyways
ornate patio
wait rlly
opal juniper
but the fact that it is a âcustom nms entityâ is probably the reason your pdc doesnât work
iâm not sure how much registering normally happens that you havenât done
humble tulip
I dont think it matters if you cast it to entity or not
ornate patio
but you can cast that to a normal bukkit entity anyways
uhhh you sure Caused by: java.lang.ClassCastException: class me.screescree.SuperiorSteed.SuperiorHorse.SuperiorHorseEntity cannot be cast to class org.bukkit.entity.Entity
shadow gazelle
Okay, fixed whatever the hell that was đ¤Śââď¸
@EventHandler
public void getSoulboundItems(PlayerRespawnEvent event) {
Player player = event.getPlayer();
for (SoulboundItemData itemData : soulboundItems) {
if (itemData.getPlayerUUID().equals(player.getUniqueId())) {
PlayerInventory inventory = player.getInventory();
final int slot = itemData.getSlot();
if (inventory.getItem(slot).getType() == Material.AIR) {
inventory.setItem(slot, itemData.getItemStack());
} else {
inventory.setItem(inventory.firstEmpty(), itemData.getItemStack());
}
soulboundItems.remove(itemData);
}
}
}
Wrong cast
shadow gazelle
Anything here that could be improved?
ornate patio
wdym
humble tulip
U casting ur nms horse to bukkit entity
ornate patio
what should i use then
opal juniper
uhhh you sure `Caused by: java.lang.ClassCastException: class me.screescree.Supe...
oh well, yours doesnât extend entity clearly
ornate patio
package me.screescree.SuperiorSteed.SuperiorHorse;
import org.bukkit.World;
import org.bukkit.craftbukkit.v1_18_R1.CraftWorld;
import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.animal.horse.Horse;
public class SuperiorHorseEntity extends Horse {
public SuperiorHorseEntity(World world) {
super(EntityType.HORSE, ((CraftWorld) world).getHandle());
}
}
thats my custom entity for now
this is what I'm casting it to:
import org.bukkit.entity.Entity;
...
// in some function:
Entity newEntity = (Entity) entity;
oh no thatâs not gonna work
humble tulip
Can't cast nms stuff to bukkit stuff
ornate patio
but you can cast that to a normal bukkit entity anyways
i might have misunderstood u then
humble tulip
It doesn't matter if u cast it to entity because craftentity is the implementation
I'm gonna test it
You say it doesn't save
ornate patio
You say it doesn't save
yeah
humble tulip
Check if it exists right after u set it
humble tulip
Does it?
opal juniper
how are you spawning it
humble tulip
Probably have to go the route of nms nbt then
humble tulip
Nbt is easier tbh
If mc handles the data
@ornate patio I'm gonna look at some stuff to see if i can help
ornate patio
how are you spawning it
In a command:
new SuperiorHorse(player.getLocation());
SuperiorHorse class acts as a wrapper:
public class SuperiorHorse {
private static SuperiorSteed plugin;
...
private SuperiorHorseEntity entity;
public static void setPlugin(SuperiorSteed javaPlugin) {
plugin = javaPlugin;
}
public SuperiorHorse(Location spawnLocation) {
entity = new SuperiorHorseEntity(spawnLocation.getWorld());
ServerLevel serverLevel = ((CraftWorld) spawnLocation.getWorld()).getHandle();
serverLevel.addFreshEntity(entity);
entity.setPos(spawnLocation.getX(), spawnLocation.getY(), spawnLocation.getZ());
...
System.out.println("TEST YES");
CraftEntity craftEntity = CraftEntity.getEntity((CraftServer) Bukkit.getServer(), entity);
PersistentDataContainer persistentDataContainer = craftEntity.getPersistentDataContainer();
persistentDataContainer.set(new NamespacedKey(plugin, "hunger"), PersistentDataType.DOUBLE, 0.5);
}
SuperiorHorseEntity is the entity itself:
public class SuperiorHorseEntity extends Horse {
public SuperiorHorseEntity(World world) {
super(EntityType.HORSE, ((CraftWorld) world).getHandle());
}
}
oh yeah you definitely need some sort of registering for the pdc
ornate patio
wdym registering
ornate patio
wdym registering
@opal juniper sorry for ping
