why doesnt this create a custom config file on enable?

        this.saveDefaultConfig();
        FileConfiguration config = this.getConfig();
        config.addDefault("enabled", true);

        boolean enabled = CheckIfEnabled();

        if(enabled){
            Bukkit.getLogger().info("test");
        }

ok

#

whoever done this

#

i hate you

    public static boolean equals(ItemStack itemstack, ItemStack itemstack1) {
        return itemstack.isEmpty() && itemstack1.isEmpty() ? true : (!itemstack.isEmpty() && !itemstack1.isEmpty() ? (itemstack.tag == null && itemstack1.tag != null ? false : itemstack.tag == null || itemstack.tag.equals(itemstack1.tag)) : false);
    }

    public static boolean matches(ItemStack itemstack, ItemStack itemstack1) {
        return itemstack.isEmpty() && itemstack1.isEmpty() ? true : (!itemstack.isEmpty() && !itemstack1.isEmpty() ? itemstack.c(itemstack1) : false);
    }

    private boolean c(ItemStack itemstack) {
        return this.count != itemstack.count ? false : (this.getItem() != itemstack.getItem() ? false : (this.tag == null && itemstack.tag != null ? false : this.tag == null || this.tag.equals(itemstack.tag)));
    }

#

this is nms code of itemstack compare

#

for some reason equals and matches are reversed

silver shuttle Apr 24, 2021, 9:09 PM

#

how do I easily get the total amount of items matching a Material in the inventory of player?

mortal hare Apr 24, 2021, 9:09 PM

#

.equals() == #ItemStack.isSimiliar() and .matches() = #ItemStack.equals()

#

wtf

mortal hare ``` public static boolean equals(ItemStack itemstack, ItemStack itemstack1) ...

that looks like obfuscated code lmao

BukkitScheduler is deprecated in some flavours of spigot. Prefer using

new BukkitRunnable() {

I'm wondering making someone verify to receive their license key on discord to receive it after they have purchased it from spigot is breaking the premium guidelines?

mortal hare Apr 24, 2021, 9:16 PM

#

The placeholder value is probably not inside the plugin itself but inside some kind of plugin or hook (for example PlaceholderAPI)

#

see plugin's documentation to hook your plugin with another plugin's placeholders

#

or if plugins placeholders are placeholderAPI implementation type seek for its documentation for getting placeholder values.

Everyone is learning, no worries. Download PlaceholderAPI and put it as a dependency inside your project
when you do in order to get the placeholder value specify the string to the placeholder api instance:

String text = "Player's thirst: %mcrealistic_thirst%";
String thirst = PlaceholderAPI.setPlaceholders(#player, text);

#Player.sendMessage(thirst);

hmm

#

bukkit's .isSimiliar() works just fine

#

but NMS one seems to be funky

#

but i need as raw method as possible

dusty herald Apr 24, 2021, 9:55 PM

#

equals has like no documentation

mortal hare Apr 24, 2021, 9:55 PM

#

since im dealing with nms

#

ofc it wouldnt

dusty herald Apr 24, 2021, 9:55 PM

#

wraith rapids Apr 24, 2021, 9:55 PM

#

itemstack's issimilar usually redirects to nms equals though

mortal hare Apr 24, 2021, 9:56 PM

#

so wtf

wraith rapids Apr 24, 2021, 9:56 PM

#

since craftstacks are just wrappers over nms data

#

and most itemstacks are craftstacks

mortal hare Apr 24, 2021, 9:56 PM

#

dusty herald

that's a NMS itemstack

#

not an bukkit one

wraith rapids Apr 24, 2021, 9:56 PM

yeah, i'm talking about you saying bukkit's issimilar working fine

dusty herald Apr 24, 2021, 9:56 PM

my bad

mortal hare Apr 24, 2021, 9:56 PM

#

#

its not

#

redirecting to nms .equals()

wraith rapids Apr 24, 2021, 9:57 PM

#

see craftitemstack

dusty herald Apr 24, 2021, 9:57 PM

#

I usually just look at the spigot api, I don't do much nms Sadge

wraith rapids Apr 24, 2021, 9:57 PM

#

most itemstacks are actually craftitemstacks aka craftstacks

#

it doesn't directly redirect to nms stack's equals, no, but the impl is almost the same

regal dew Apr 24, 2021, 9:57 PM

#

NMS has a static .equals() method afaik

wraith rapids Apr 24, 2021, 9:58 PM

#

that is, it compares the nbt tag compound

mortal hare Apr 24, 2021, 9:58 PM

#

#

once again

#

its not redirecting

#

that's a craftitemstack

wraith rapids Apr 24, 2021, 9:58 PM

literally read what i just said

mortal hare Apr 24, 2021, 9:58 PM

#

oh

mortal hare Apr 24, 2021, 9:58 PM

#

regal dew NMS has a static .equals() method afaik

yes

#

but it returns that stone is equal to emerald_block lol

wraith rapids Apr 24, 2021, 9:59 PM

#

that's haram

#

yeah i don't know how that'd happen

#

i mean, the impl of it is this

    public static boolean equals(ItemStack itemstack, ItemStack itemstack1) {
        return itemstack.isEmpty() && itemstack1.isEmpty() ? true : (!itemstack.isEmpty() && !itemstack1.isEmpty() ? (itemstack.tag == null && itemstack1.tag != null ? false : itemstack.tag == null || itemstack.tag.equals(itemstack1.tag)) : false);
    }

#

i might be blind, but I'm not seeing a material comparisn there

#

only the tag which holds the meta

#

or, well, nms doesn't use materials, but you know what i mean

yea

🤷‍♂️

wraith rapids Apr 24, 2021, 10:01 PM

#

use ItemStack.matches instead

#

it looks to be doing the comparison properly

mortal hare Apr 24, 2021, 10:02 PM

#

the thing is

#

matches is bukkit's equals()

#

its strict on item amount

#

as you can see

wraith rapids Apr 24, 2021, 10:02 PM

#

literally copy the impl but drop the amount check i guess 👀

mortal hare Apr 24, 2021, 10:02 PM

but that's really bizarre

it looks like if mapping just fucked up

wraith rapids Apr 24, 2021, 10:03 PM

Hey. I am having a problem if anyone can help me. I run a bungeecord server and I have been having this problem where after someone teleports, they become invisible to other players and their body gets left back at their pre teleport spot, but it doesnt move and it cant be moved. Killing that player does seem to fix the issue, but that isnt an option for me since most of the time players teleport to go into a minigame or something. I have read that this is a problem with vanilla minecraft, but I have not found any solutions for it.
Any help would be appreciated.

wraith rapids Apr 24, 2021, 10:30 PM

#

it could be null

#

and if it's null, that method will throw an exception

gaunt eagle Apr 24, 2021, 10:30 PM

#

Why was it just this when others wouldn't be the problem xd?

getString is annotated as @Nullable

wraith rapids Apr 24, 2021, 10:31 PM

that is why only the String one is raising the warning

tranquil viper Apr 24, 2021, 10:31 PM

#

oh i figured it out

gaunt eagle Apr 24, 2021, 10:31 PM

#

understood, I guess it won't be a problem. Thanks ^^

wraith rapids Apr 24, 2021, 10:31 PM

#

if you want to be robust, grab the string into an intermediate variable and null check

tranquil viper Apr 24, 2021, 10:31 PM

#

ItemFlag.HIDE_POTION_EFFECTS exists

wraith rapids Apr 24, 2021, 10:31 PM

#

and give the end user an informative error message

#

if the end user configures a null value for that key, this will explode with an exception

#

but that's 'fine'

#

as you probably shouldn't configure a null value for that key

gaunt eagle Apr 24, 2021, 10:32 PM

#

@wraith rapids IDE saved the warning by editing it in this way. Does it create a problem?

#

Objects.requireNonNull

quaint mantle Apr 24, 2021, 10:32 PM

wraith rapids Apr 24, 2021, 10:32 PM

#

that will still explode with an exception, yes

#

it just indicates your intent that you want it to be not null more clearly

cinder thistle Apr 24, 2021, 10:32 PM

#

just have a null check

#

although I wouldn't consider that a big issue

gaunt eagle Apr 24, 2021, 10:33 PM

#

wraith rapids it just indicates your intent that you *want* it to be not null more clearly

xD

#

thanks

cinder thistle Apr 24, 2021, 10:33 PM

#

considering that the only way afaik that it could be null is if it's missing from the config period

wraith rapids Apr 24, 2021, 10:33 PM

#

the difference between now and then is that now you are willingly taking something that might be null and blowing up if it is, and then you weren't; you might not have realized that it was nullable, which would have been a programming mistake

#

which is why it was giving a warning then and not now; now your blowing up is intentional

#

that said yeah it isn't an issue and just wrapping it with that is fine

#

but if you want to be robust you could nullcheck it and print a message

#

you probably would also want to nullcheck the return value of Bukkit.getWorld, so the end user can see if they misconfigured their world

#

Locations with a null world tend to explode arbitrarily when passed around, which can be difficult to track down

       }

Only problem is that instead of actually putting it in the inventory, it just doubles the cursor item (?)

#

I'm assuming that it's just that as soon as the code puts it in that slot, it gets picked up as you click the slot

Would adding some kind of delay help with that?

Eclipse has a checkbox when creating a project to create a module-info.java. You can uncheck that

#

Nope, you're fine

It's just the module-info.java that denotes it as modular

young knoll Apr 25, 2021, 1:03 AM

Yeah you can’t do that

You need to call equalsIgnoreCase twice

quaint mantle Apr 25, 2021, 1:04 AM

#

on two separate lines?

young knoll Apr 25, 2021, 1:04 AM

#

You can connect them with || on the same line

#

You just need to call the method fully each time

#

Because || works on booleans, not strings

#

You could also uses arrays.asList(your, options, here).contains(string)

#

Probably a bit slower though

this is how it looks in my datapack

same resourcepack so they have the same ascent and height values

in my datapack I use unicode for both the icons and negative space which closes the gaps between the icons

#

doesnt seem to want to work in my plugin tho

#

        String negative_space = "\uF802";

        String empty_mana = "\uE003";
        String half_full_mana = "\uE002";
        String full_mana = "\uE001";

        String mana_bar = "";

        int i;
        for (i=1 ; i<=10; i++)
            mana_bar += full_mana;
            mana_bar += negative_space;

        player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new ComponentBuilder(space).append(TextComponent.fromLegacyText(mana_bar)).create());

whats the best way to make a request system from a player to player

#

so like someone does a command

#

that has some player in its args

#

and then that player has to do a command

#

to accept or deny the request

cinder thistle Apr 25, 2021, 5:06 AM

#

Piece by piece

#

You just have a map of requests and when a player runs the accept/deny command it checks if that request is in the map

#

And you can use json hover n click if you’re fancy

tame wolf Apr 25, 2021, 5:09 AM

#

ok

#

i dont understand

cinder thistle Apr 25, 2021, 5:15 AM

#

The request create command adds a request to a map

#

The accept/deny command checks the map and does whatever you want after accepting or denying

#

And if it IS in the map it gets removed

This is the same code of mine

#

lol

eternal oxide Apr 25, 2021, 9:16 AM

#

No, all you are showing is getting commands

#

Your registering is broken because you are doing it wrong

#

Which is why you are throwing npe

cold field Apr 25, 2021, 9:16 AM

#

Mh, it works

#

...

#

We are telling the same thing

eternal oxide Apr 25, 2021, 9:17 AM

#

it works, except for you coming asking how to silence an npe with suppress warnings

cold field Apr 25, 2021, 9:18 AM

#

The npe is thrown every time even if you register the command in the plugin.yml

eternal oxide Apr 25, 2021, 9:18 AM

#

You should not have ANY npe. You are doing it wrong

cold field Apr 25, 2021, 9:18 AM

#

Maybe you are right

eternal oxide Apr 25, 2021, 9:18 AM

#

As I said, your registering reflection code is wrong. The above code I just posted is correct

cold field Apr 25, 2021, 9:19 AM

#

But I dont know where I'm doing it wrong

#

Can you tell me?

eternal oxide Apr 25, 2021, 9:19 AM

#

I just told you. Use the code or don't. I'm not bothered

cold field Apr 25, 2021, 9:20 AM

#

But why it works if I'm doing it wrong...

#

I checked the source code and I'm editing the same command map that your code is using

eternal oxide Apr 25, 2021, 9:20 AM

#

You are throwing an NPE, its NOT working!

It's a warning into the IDE

#

Is there a stacktrace being thrown, yes or no?

cold field Apr 25, 2021, 9:24 AM

#

no

#

If i do the command it works

minor vapor Apr 25, 2021, 9:25 AM

#

Alright, then the IDE is telling you something CAN be null and you need to check for it, simple

#

just add a null check, that's all that it's asking for

cold field Apr 25, 2021, 9:26 AM

#

what I was asking is how can it be null if I'm adding the command inside the commandMap that getCommand use

#

to retreive the command

minor vapor Apr 25, 2021, 9:26 AM

#

because you're using reflection and the field and such can be null

dusty herald Apr 25, 2021, 9:27 AM

#

getCommand is always nullable

#

that's why I always only execute code if it isn't null DogKek

#

not checking for nullables is silly

it's annotated Nullable for a reason

This event will fire as cancelled if the vanilla behavior is to do nothing (e.g interacting with air). For the purpose of avoiding doubt, this means that the event will only be in the cancelled state if it is fired as a result of some prediction made by the server where no subsequent code will run, rather than when the subsequent interaction activity (e.g. placing a block in an illegal position (BlockCanBuildEvent) will fail.

why do you need to detect a reload?

quiet ice Apr 25, 2021, 10:35 AM

#

If you just wish to detect reloads you could check if there are online players, it is usually a dead giveaway of a reload

solemn shoal Apr 25, 2021, 10:36 AM

#

not in the case of small servers

solemn shoal Apr 25, 2021, 10:36 AM

#

eternal oxide why do you need to detect a reload?

because my plugin halts the server for 5 seconds on startup

(intentionally)

There are plenty of ways to detect an reload though

solemn shoal Apr 25, 2021, 10:38 AM

its so you'd feel a noticeable slowdown in your startup

no point in doing it on reload tho

Listening for Commands for example are an easy way (you'd need to store it in a persistent file to remind your future self)

eternal oxide Apr 25, 2021, 10:48 AM

your plugin instance will be different so you shoudl just check the presence of any ticket

solemn shoal Apr 25, 2021, 10:48 AM

doesnt work either @eternal oxide
