Then your location method you are using is wrong

get the entities location. The code I gave you definitely works

harsh kayak Mar 28, 2021, 4:12 PM

it doesnt do exactly what you said it would

but now i dont have to modify it to do a 221

and the wall is diagonal

eternal oxide Mar 28, 2021, 4:19 PM

it does exactly what I said it does. The wall will be 90 degrees to the player and 2x3

Is it vital that it's exactly 60 seconds and is representative of real world time? If so use a scheduled service executor, otherwise use the bukkit scheduler.

It’s not an api but it’s weird still

#

Do you build it right?

quiet ice Mar 28, 2021, 4:58 PM

#

maybe check whether the method really exist with a bytecode editor or something similar

#

Although, it is basically a given that the method does not exist

#

If Java tells that it didn't find a method, that's because it wasn't there in the first place

ivory sleet Mar 28, 2021, 4:59 PM

My guess he might be using plugman or just build it wrongly

accessing another plugins API before the server is fully started is not a good idea.

run yoru setWelcome 1 tick after your onEnable has finished

oak mica Mar 28, 2021, 5:00 PM

Hi,
I was wondering if someone could help me figure out how to save my hashmap in onDisable and read it in onEnable. My hashmaps are:

    public static HashMap<Player, BossBar> bossbar = new HashMap<Player, BossBar>();

Until now, I have found ```
for (Entry<String, String> set : money.entrySet()) {
getConfig().set("money." + set.getKey(), set.getValue());
}
saveConfig();

for (String users : getConfig().getConfigurationSection("money").getKeys(false)) {
money.put(users, getConfig().getString("money." + users));
}

eternal oxide Mar 28, 2021, 5:01 PM

You can;t read/create player objects in onEnable, unless its a reload

oak mica Mar 28, 2021, 5:01 PM

eternal oxide You can;t read/create player objects in onEnable, unless its a reload

when the server is starting there are no player objects at all

That’s good though

eternal oxide Mar 28, 2021, 5:11 PM

you are correct

#

loadbefore is not depend

unreal quartz Mar 28, 2021, 5:12 PM

if you're making an API, you shouldn't be explicitly defining any loadbefores as you can't possibly predict what will depend on it

    }

SpigotMC - High Performance Minecraft

Resource - A guide to 1.14 - PersistentDataHolder API

Hey there,

after 1.13.2 already got the new CustomItemTagContainer API, 1.14 is expanding on this new MetaData API and we will look into it a bit...

i will try this

quiet ice Mar 28, 2021, 6:58 PM

#

NBT is 2000% more complicated than PDC

oak mica Mar 28, 2021, 6:58 PM

#

but i dont understance concept of that

quaint mantle Mar 28, 2021, 6:59 PM

#

oak mica i will try this

U must be over 1.14

quiet ice Mar 28, 2021, 6:59 PM

#

NBT is a wrapper around PDC as far as I know thanks to bukkit patches

young knoll Mar 28, 2021, 6:59 PM

#

Other way

quaint mantle Mar 28, 2021, 6:59 PM

#

quiet ice NBT is 2000% more complicated than PDC

But u can do so many things with it.

young knoll Mar 28, 2021, 6:59 PM

#

PDC wraps NBT

quiet ice Mar 28, 2021, 6:59 PM

#

No, the other way around

young knoll Mar 28, 2021, 6:59 PM

#

And you can do almost everything you can with NBT using PDC

eternal oxide Mar 28, 2021, 6:59 PM

#

NBT is the root, PDC is the wrapper API

quaint mantle Mar 28, 2021, 6:59 PM

#

Just use one of them, the one u like the most

quiet ice Mar 28, 2021, 6:59 PM

#

okay, then I am wrong

#

NBT requires NMS, would not recommend it though

young knoll Mar 28, 2021, 7:00 PM

#

Well one is an API that won't need changing for each version

#

The other is NMS

oak mica Mar 28, 2021, 7:01 PM

#

I don't understand either

young knoll Mar 28, 2021, 7:02 PM

#

You have Javadocs and a tutorial

quiet ice Mar 28, 2021, 7:02 PM

#

I am a bit new to the convo, so what exactly do you want to store?

oak mica Mar 28, 2021, 7:02 PM

#

Does comparing item metas compare itom names?

quiet ice Mar 28, 2021, 7:02 PM

#

oak mica I don't understand either

Just wait till you see Sponge's data API

oak mica Mar 28, 2021, 7:02 PM

#

quiet ice I am a bit new to the convo, so what exactly do you want to store?

Basically i have a sword with a right click ability

#

and i want ability to work even when item renamed

young knoll Mar 28, 2021, 7:03 PM

#

oak mica Does comparing item metas compare itom names?

yes

quiet ice Mar 28, 2021, 7:03 PM

#

Ah, so first get the PDC which is the itemMeta

eternal oxide Mar 28, 2021, 7:03 PM

#

Yep, Store a type flag in the PDC.

oak mica Mar 28, 2021, 7:03 PM

#

ok

quiet ice Mar 28, 2021, 7:03 PM

#

Then store a Byte in the PDC, which will act as a flag, you can then remove it if you want to remove the action

oak mica Mar 28, 2021, 7:03 PM

#

so itemMeta.getPersistentDataContainer().set(key, PersistentDataType.DOUBLE, Math.PI); line basically ?

quiet ice Mar 28, 2021, 7:04 PM

#

Yes, somewhat like that

oak mica Mar 28, 2021, 7:04 PM

#

NamespacedKey key = new NamespacedKey(pluginInstance, "our-custom-key");
ItemMeta itemMeta = itemStack.getItemMeta();
PersistentDataContainer container = itemMeta.getPersistentDataContainer();

if(container.has(key , PersistentDataType.DOUBLE)) {
    double foundValue = container.get(key, PersistentDataType.DOUBLE);
}

#

this is code to access

#

right?

quiet ice Mar 28, 2021, 7:05 PM

#

This should work

#

Altough you can also use getOrDefault if you wish

oak mica Mar 28, 2021, 7:05 PM

#

ok

eternal oxide Mar 28, 2021, 7:05 PM

#

not a good idea if you want to do somethign only if the flag exists

quiet ice Mar 28, 2021, 7:06 PM

#

Always depends on the usecase I would say

eternal oxide Mar 28, 2021, 7:07 PM

#

yep

young knoll Mar 28, 2021, 7:07 PM

#

PDC is great for APIs

#

My plugin supports adding a thirst replenishment value to any item with PDC

oak mica Mar 28, 2021, 7:08 PM

Ok doesn't matter

Is there a way to add custom nbt data to an armor stand? I've already tried NMS, but couldn't get it working for entities. Is this possible without the use of external API's?

eternal oxide Mar 28, 2021, 7:22 PM

#

PDC

worldly ice Mar 28, 2021, 7:24 PM

#

so, would it be something like armorStand.getPersistentDataContainer().set(...)?

eternal oxide Mar 28, 2021, 7:25 PM

#

yes

I'm basically trying to make a /heal and /heal <player> command..
When I have perms for heal.heal I can heal myself and heal other players
and When I have perms for heal.heal.others I can't heal myself or other players.. I want to do it so If I do /heal it heals the one who did it, and If I do /heal <player> It heals arg1

#

This is the code

dusty herald Mar 28, 2021, 7:53 PM

so if you don't have the heal.heal permission, you get returned

you need heal.heal and heal.heal.others

I'd suggest reading the link he sent

#

ohh

#

I didn't see it

#

I can't understand anything xd...

dusty herald Mar 28, 2021, 7:59 PM

#

so if I were to do something like that with permissions, I'd probably do this

switch(player.getPermission()){
    case "heal.heal":
    
    break;
    case "heal.heal.others":
    
    break;
    default:
       player.sendMessage("You don't have permission");
    break;
}```

#

not because I love switch statements tho

Hi, I was wondering if someone could help me stop renaming items in an anvil but keeping the ability to apply enchantment books. I have some code right now:
@EventHandler(priority = EventPriority.MONITOR)
public void onInventoryClick(InventoryClickEvent e){
if(!e.isCancelled()){
HumanEntity ent = e.getWhoClicked();
if(ent instanceof Player){
Player player = (Player)ent;
Inventory inv = e.getInventory();
if(inv instanceof AnvilInventory){
InventoryView view = e.getView();
int rawSlot = e.getRawSlot();
if(rawSlot == view.convertSlot(rawSlot)){
if(rawSlot == 2){
ItemStack item = e.getCurrentItem();
if(item != null){
ItemMeta meta = item.getItemMeta();
if(meta != null){
if(meta.hasDisplayName()){
String displayName = meta.getDisplayName();
e.setCancelled(true);
}
}
}
}
}
}
}
}
}
which I got from: https://bukkit.org/threads/inventory-anvil-events.142990/
However, this stops using anvils altogether, not just renaming. I was wondering if someone could help me solve this problem.

As if the custom items were renamed, their ability stops working

oak mica <@!220605553368498176>

Im probably too biased regarding code structure and design patterns so i would probably just scrap and re-write it. But ill give you the low hanging fruits.
For one: Single character variable names are pretty much a no-go unless they are used int 2 or 3 consecutive lines.
Next: max mana is a hard coded constant
Then: Hard referencing a Player object is a bad idea in most cases. Use the UUID instead.
Finally (and most important):
Your code doesnt work.

Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {
            public void run() {
                for (Player p : Bukkit.getOnlinePlayers()) {
                    if (!(hasMaxMana(p))) {
                        continue;
                    }
                    if (getPlayerMana(p) < MAX_ArcanePower){
                        addMana(p, 1);
                    }
                    bossbar.get(p).setTitle("Arcane Power: " + getPlayerMana(p));
                    bossbar.get(p).setProgress(getPlayerMana(p)/ MAX_ArcanePower);
                    bossbar.get(p).setVisible(true);
                    bossbar.get(p).addPlayer(p);
                }
            }
        }, 0L, 20L);

This will just skip every player unless he has max mana. And in that case no mana is added.

    public void setBanner(String clan, BannerMeta meta) {
        clanData.set("clan." + clan + ".banner", meta.serialize());
        saveClanData();
    }

It gives me:

Pretty sure you should just be passing the section

Not the values

quaint mantle Mar 28, 2021, 10:20 PM

The method deserializeObject(Map<String,?>) in the type ConfigurationSerialization is not applicable for the arguments (ConfigurationSection)

#

Should I just do a typecast?

#

Caused by: java.lang.ClassCastException: class org.bukkit.configuration.MemorySection cannot be cast to class java.util.Map (org.bukkit.configuration.MemorySection is in unnamed module of loader 'app'; java.util.Map is in module java.base of loader 'bootstrap')

return (BannerMeta) ConfigurationSerialization.deserializeObject((Map<String, Object>) cs);

young knoll Mar 28, 2021, 10:22 PM

Huh

#

I normally just work with item stacks, so it handles that itself

quaint mantle Mar 28, 2021, 10:23 PM

#

My plugin has clans, and each clan can set their flag. If the clan is the top clan then their flag replaces all banners at spawn

#

To do that it looked to me like the best way is just save the banner meta

#

Doesn't seem to want to load properly though, and the only method of a ConfigurationSection that returns a Map<String, Object> is getValues()

It doesn't look like BannerMeta has a constructor or a valueOf() or deserialize() method.

i think it's cause to register a new placeholder with the expansion this is the method public String onRequest(OfflinePlayer player, String identifier) { so it requires a offlineplayer

How do I set the base colour of an already-placed banner? Here's what I have so far:

Block bannBlock = ((Player) sender).getWorld().getBlockAt(-88, 72, -194);
CraftBanner banner = new CraftBanner(bannBlock);
BannerMeta meta = getBanner("clan2");
banner.setBaseColor(DyeColor.RED);
banner.setPatterns(meta.getPatterns());
banner.update(true);

The patterns are applied to the banner but the base colour of the banner is not changed from its original.

Is there any better way to set the base colour of a banner than this abomination? I tried using Banner.setBaseColor() and it didn't work because it's in BlockData now, and I tried using Banner.setType() to set it to another banner material but that destroyed all the other block data like rotation and whether it's attached.

I tried this but it didn't work (the type casts were invalid):

boolean isAttached = ((Attachable)bd).isAttached();
BlockFace facing = ((Directional)bd).getFacing();

Arrow is a projectile last I recalled

how do I get the data out of a packet from a packet listener

deft geode Mar 29, 2021, 1:47 AM

#

wet breach Arrow is a projectile last I recalled

Ok arrow is an interface

wet breach Mar 29, 2021, 1:47 AM

#

Sure, and you can cast it to Projectile as well

deft geode Mar 29, 2021, 1:48 AM

#

wet breach Sure, and you can cast it to Projectile as well

but I'm confused

#

how am I supposed to create an instance of arrow

#

It's abstract

young knoll Mar 29, 2021, 1:49 AM

#

Pretty sure it just takes the class

#

Yes, it does

wet breach Mar 29, 2021, 1:50 AM

#

There is AbstractArrow and there is Arrow

deft geode Mar 29, 2021, 1:50 AM

#

so literally Player.launchProjectile(Arrow.class);

young knoll Mar 29, 2021, 1:51 AM

#

Mhm

wet breach Mar 29, 2021, 1:51 AM

#

Yep

#

That easy 🙂

#

the method should take care of the spawning for you

deft geode Mar 29, 2021, 1:51 AM

#

Phew

#

I thought I had to extend it whatever

#

*implement

wet breach Mar 29, 2021, 1:51 AM

you can if you really wanted to. IE want custom projectile objects etc

deft geode Mar 29, 2021, 1:52 AM

#

wet breach you can if you really wanted to. IE want custom projectile objects etc

I would advise against extending bukkit classes

#

Use PDC instead

wet breach Mar 29, 2021, 1:53 AM

#

Depends on the purpose

#

PDC doesn't create custom entities but rather stores custom information

young knoll Mar 29, 2021, 1:54 AM

#

Correct

#

Which is basically all you can do without a client mod

wet breach Mar 29, 2021, 1:54 AM

#

You don't need a client mod for custom entities

#

you do if you want to change the look of said entity

#

or should say, the look of said entity with custom graphics XD

open vapor Mar 29, 2021, 1:55 AM

#

how do I get the raw data from a packetlistener or know what data to read from

wet breach Mar 29, 2021, 1:55 AM

#

Depends how you are doing it

young knoll Mar 29, 2021, 1:55 AM

#

If you aren’t changing the look you generally just need to store extra information, unless you are doing custom mob AI

limber dust Mar 29, 2021, 1:56 AM

#

young knoll Which is basically all you can do without a client mod

unless they are creating a nms entity, but from what im reading is not what they are doing

wet breach Mar 29, 2021, 1:56 AM

#

If you are using ProtocolLib it has methods for getting the raw packet data

open vapor Mar 29, 2021, 1:56 AM

#

what is the method

wet breach Mar 29, 2021, 1:56 AM

#

if you are using NMS you would need to cast to get it

open vapor Mar 29, 2021, 1:56 AM

#

i am using protocollib

wet breach Mar 29, 2021, 1:56 AM

#

well they have documentation for their plugin

#

@limber dust no they are not, was just making a point there is times where it is valid to extend or implement bukkit classes/interfaces

limber dust Mar 29, 2021, 1:57 AM

#

ye

wet breach Mar 29, 2021, 1:57 AM

#

I do it all the time for custom player objects 🙂

limber dust Mar 29, 2021, 1:58 AM

#

makes sense

#

i tend to just have a getPlayer() method (mainly cause i use uuids, not actual players)

Hey guys im using the BlockPistonExtendEvent and BlockPistonRetractEvent to try and cancel the event if they move a specific block but when I am checking the event block I get the piston as the location instead of the block it is moving any ideas?

I can't seem to find it

young knoll Mar 29, 2021, 1:59 AM

#

Choco is very adamant about not extending bukkit

#

With some exceptions

wet breach Mar 29, 2021, 1:59 AM

#

Well as I said it just depends what you are doing. For most things it isn't necessary

sullen marlin Mar 29, 2021, 2:02 AM

#

The docs say the same

#

You don't extend bukkit classes unless they're obviously meant to be

young knoll Mar 29, 2021, 2:04 AM

#

I believe the only classes I’ve ever extended are JavaPlugin and BukkitRunnable

sullen marlin Mar 29, 2021, 2:05 AM

Yup, that's basically the extent of what it's meant to be

how do I get out of the asynchronous scope? I need to call a synchronous function from an anysychronous one

drowsy helm Mar 29, 2021, 2:20 AM

#

whats the context of this

#

usually theres a better way than calling from async

young knoll Mar 29, 2021, 2:21 AM

#

Use a scheduler

#

With just a runTask

#

I am assuming it’s the async packet listener

deft geode Mar 29, 2021, 2:21 AM

#

Is there a way to make an arrow (from Player.launchProjectile()) fly faster using a vector?

@deft geode the length of the vector should determine its speed

deft geode Mar 29, 2021, 2:25 AM

or the magnitude I think if you wanna get techincal

I'm more asking how to combine the vector with the way the player is facing

candid galleon Mar 29, 2021, 2:28 AM

#

well you have the way that the player is facing with Player#getLocation.getDirection

deft geode Mar 29, 2021, 2:29 AM

#

I cant just use new Vector(3.0, 3.0, 3.0) because that's 1) not where the player is facing 2) i have no idea if they're near there

candid galleon Mar 29, 2021, 2:29 AM

#

that's already normalized, so you just have to multiply it by the power you want

#

@deft sedge assuming you have the ItemStack, you'd get its ItemMeta and cast it to Book

young knoll Mar 29, 2021, 2:29 AM

#

Use player.getEyeLocation.getDirection

#

And then .multiply

deft sedge Mar 29, 2021, 2:31 AM

basically just gets the meta if the item player is holding

candid galleon Mar 29, 2021, 2:31 AM

#

quick tip, you don't need the else {

deft sedge Mar 29, 2021, 2:31 AM

yea i know

candid galleon Mar 29, 2021, 2:31 AM

#

aight

deft sedge Mar 29, 2021, 2:31 AM

#

Just wanted to be shure lol

candid galleon Mar 29, 2021, 2:31 AM

#

well can you try meta.getPages()?

deft sedge Mar 29, 2021, 2:31 AM

#

yea

#

and then do I just do an if statement to check if the stuff is equal to this

#

i basically need to get the words form the pages

#

into a variable

#

sorry if it's obvious to you i'm kinda new 😅

candid galleon Mar 29, 2021, 2:32 AM

#

right, so something like
List<String> text = meta.getPages();

would put the text contents of the pages into the variable text

#

no worries, it's always fun seeing new people learn

#

@sick ravine >:(

deft sedge Mar 29, 2021, 2:33 AM

#

ok thanks

#

when I do that list is bolded in red

candid galleon Mar 29, 2021, 2:33 AM

#

try ~~highlighting~~ hovering over it

#

what does it say?

deft sedge Mar 29, 2021, 2:33 AM

just had to import it

candid galleon Mar 29, 2021, 2:34 AM

there ya go

deft sedge Mar 29, 2021, 2:34 AM

#

and then I can do the same thing for specific pages right

sick ravine Mar 29, 2021, 2:34 AM

#

hmm
List<String> pages = meta.getPages();

deft sedge Mar 29, 2021, 2:34 AM

#

like get page and then a number

candid galleon Mar 29, 2021, 2:34 AM

#

you know what Lists and Arrays are right?

deft sedge Mar 29, 2021, 2:34 AM

#

yea sort of

#

a list is just a list of things

#

right

candid galleon Mar 29, 2021, 2:34 AM

#

yeah basically

deft sedge Mar 29, 2021, 2:34 AM

#

not so sure on arrays

wet breach Mar 29, 2021, 2:34 AM

#

deft geode I cant just use `new Vector(3.0, 3.0, 3.0)` because that's 1) not where the play...

there is methods in the API for turning locations into vector's and second you definitely can just create a new vector and set it manually if you really wanted to.

deft sedge Mar 29, 2021, 2:35 AM

#

trying to learn coding while doing something I enjoy

candid galleon Mar 29, 2021, 2:35 AM

#

a list is basically an implementation of an array

deft sedge Mar 29, 2021, 2:35 AM

#

I am kinda picking it up

#

ok

candid galleon Mar 29, 2021, 2:35 AM

#

for beginner purposes you can consider them similar

#

tldr the first page would be pages.get(0), second would be pages.get(1), etc.

#

if it was an array (it isn't), you'd do pages[0] for the first page

deft sedge Mar 29, 2021, 2:35 AM

#

yea

#

i understand that

candid galleon Mar 29, 2021, 2:36 AM

#

@sick ravine 🥜 gallery emojis imagine 😄

deft sedge Mar 29, 2021, 2:36 AM

#

I think i can figure it out on the website you gave me

#

i can just grab the contents of specific pages and store them to variables

candid galleon Mar 29, 2021, 2:36 AM

#

you could, depends on how you're using it 😛

deft sedge Mar 29, 2021, 2:37 AM

#

List<String> text = meta.getPage(1);

#

would that get data of first page

#

or second if it starts with 0

candid galleon Mar 29, 2021, 2:37 AM

#

it would get the second page

deft sedge Mar 29, 2021, 2:37 AM

#

yea

candid galleon Mar 29, 2021, 2:38 AM

#

generally indexes start at 0

deft sedge Mar 29, 2021, 2:38 AM

#

bc it sarts with 0

#

i don't know if I formatted it right tho

#

it is red underlined

#

Oh i think i figured it out

#

it's this

#

List<String> text = meta.getPageCount(0);

#

and that would give the first page

#

to the variable text

candid galleon Mar 29, 2021, 2:39 AM

#

getPageCount returns the number of pages

deft sedge Mar 29, 2021, 2:39 AM

#

yea

candid galleon Mar 29, 2021, 2:39 AM

#

so what's the 0 for?

deft sedge Mar 29, 2021, 2:39 AM

#

first

candid galleon Mar 29, 2021, 2:39 AM

#

but you're getting the number of pages

deft sedge Mar 29, 2021, 2:39 AM

#

I thougt it was the index

#

like i just want the stuff on page 0

candid galleon Mar 29, 2021, 2:40 AM

#

em

deft sedge Mar 29, 2021, 2:40 AM

The first returns a list of pages

deft sedge Mar 29, 2021, 2:40 AM

#

it

young knoll Mar 29, 2021, 2:40 AM

#

The second returns a number

what do you think getPageCount returns?

the page number

#

ohh

#

no

#

it doesnt hurt to read methods lol

deft sedge Mar 29, 2021, 2:42 AM

#

yea

#

so to get the contents of page 1 I would do String text = meta.getPage(1);

#

wich would return page 2 bc of how ther're numbered i know

sick ravine Mar 29, 2021, 2:44 AM

#

in IntelliJ IDEA, if you hover over a method, its description will be highlighted
