How do you represent long in config?
I cant find the way of representing them
quaint mantle
How do you represent long in config?
wdym u just put ur long value into the config
tardy delta
just as a literal?
tender shard
mynumber: 3

Its giving an cast exception

because your using int or something

what config framework do you even use?

what ur doing? getLong?

tardy delta
dont use a raw get

what ur doing? getLong?
yes
tardy delta
that returns an onbject ah wait thats no fileconfiguration
tender shard
it looks you just use a Map<String,Object>
sterile token
Yes its configuration serikliazable
tender shard
check if it's an int, if yes cast it to int
tardy delta
ig getLong gets a Number and calls ::longValue
tardy delta
well its a raw map

well its a raw map
Thats how config seriazable works

anyways is there a dif between ? and Object as generic params?
or does ? mean that no assumption can be made about the type and Object that everything will match?
hazy parrot
I mean Object is just object, and because every class in java inherites Object, means you can put basically anything
end effect is basically same
i mean you also if you have method for example
public void foo(List<Object> smth) {...}
public static void main(String[] args) {
List<?> smth2 = ...;
foo(smth2); // will not work
}
because ? might not be Object, even if its impossible in pratcice

anyways is there a dif between ? and Object as generic params?
verty
Object is just a type
? means any type
? extends T means as long as the type is a derivative or T itself its fine
? super T means as long as the type is an antiderivative or T itself its fine
this is why you often when writing higher ordered methods use wildcards
void takeSupplier(Supplier<? extends Animal> supplier)
here the type Supplier<Dog> (suppose Dog extends Animal)) is acceptable
since it doesn't matter, as long as we know the supplier will yield an instance of Animal when calling get()
warm mica
the max we have is 3 hours networking after eachother

ivory sleet
this is also why
void takeConsumer(Consumer<? super Dog> consumer)
here we use super since a Consumer<Animal> should be fine as it doesn't really use any methods from a Dog derivative type

When downloading plugins on spigotmc I got a 403 error, anyone know why?
Try to change your user agent. Cloudflare could also be blocking your requests. You could use spiget for downloading them
warm mica
It's also possible that the resource is payed
Spiget is only for free ones I believe
Or it's using an external link
raw sky
It is iirc, we do have detection for that in our library not sure if they used it
External links handled, GitHub’s handled
We do have to download 200k plugins or more though
remote swallow
why would you be downloading that many
raw sky
why would you be downloading that many
We have to index every single plugin on spigot and it’s data
remote swallow
you have to do that because?
raw sky
Building a plug-in
wet breach
o.O
raw sky
We have to download every single plugin ever on spigot
We got all the .jar files out of the 108.9k plugins out rn or so
It’s rough man
We gotta support every main plugin distributor out there rn
next plume
Who is "we"?
raw sky
Spigotmc is coded, but I’m making a plug-in system to cover other websites
raw sky
Who is "we"?
We as the plug-in team
next plume
"The plug-in team" for what?
raw sky
For a “plugin package manager” plugin
next plume
So why do you need the .jar files themselves?
remote swallow
you mean the spigot resource page? or google?
raw sky
So why do you need the .jar files themselves?
We need to save the sha256 so we can recognize any plugin
raw sky
you mean the spigot resource page? or google?
Wdym?
Not sure if your talking to me or not
Ohhh
remote swallow
idk why people would need that as a plugin, most server hosts supply a plugin browser
raw sky
All from in game, automatic updates, malware checking, installing and enabling without restart etc
Never used a host like that
I meant I’m making a system that can download from Hangar, Modrinth, curseforge, possibly Ore, etc not just spigotmc
echo basalt
can't you just index all the files and redirect downloads to spigot's cdn?
How would you handle premium plugins, deleted stuff
next plume
Not to mention dozens of old version of plugins.
raw sky
We index “id:name” currently
next plume
Dev builds.
raw sky
Not to mention dozens of old version of plugins.
We are gonna support every single version on spigotmc, we will cover 90% of plugins a server has that’s not custom made
Even if it’s old
tiny plume
I'd imagine there are far more efficient ways to achieve what you're wanting to do rather than downloading every single plugin across all platforms?
raw sky
I am sure there is, can’t really think of one rn
We have to store the sha256 so we can support multiple stores
We are just storing it in a database and using a rest api
next plume
- Search with Google.
- Download from the original source.
- Profit!
raw sky
How are we going to search for 500k plugins though
500k different builds atleast, not sure how many individual plugins we will support
next plume
Are you actually distributing the plugins? i.e., people are downloading your copies?
raw sky
We are downloading inside of our plugin from spigotmc currently
We are getting the download link from spiget, if it’s external then we calculate how to download from there
We support direct downloads and GitHub ontop of spigotmc
We have a method to manually put a download link thougu
next plume
You're providing a service? A plugin catalog? Where do the users ultimately download from? Your servers?
tiny plume
I'm guessing it's this based on his status https://www.spigotmc.org/resources/plugin-portal.108700/
From what I can get, he's downloading each plugin to get a shasum in order to prevent them listing the same plugin several times
so I'd imagine that they download each jar, grab the shasum store it (along with the download url and whatever else) and then delete it off
raw sky
Will also let us recognize already downloaded plugins, our current plugin has a few bugs but we remade it in kotlin, made a library, updated the rest api etc and we are releasing that tomorrow
tiny plume
then when someone requests for a plugin to be installed onto their server, it uses their database to fetch a download url (such as from github, spigot cdn etc) and downloads it to the server
yep
raw sky
Pretty close yea
next plume
OK. I don't really see the point, but good luck.
raw sky
Shasum isn’t in the current version sadly
young knoll
I mean I guess updating from in game is nice

spigotmc doesn't scan for malware lol, optic does but he's only one guy
raw sky
Can he not scan the entire storage
ancient plank
no
next plume
There have been hundreds of plugins with malware hosted on Sipgot.
ancient plank
he does it the same way you do it, download a hundred+ plugins with spiget, then use his custom resource to scan
raw sky
We will be scanning for malware soon though
Ah so it’s quite slow I would assume
We will have virustotal api integration, we will add our own custom back door protection ontop of that
hazy parrot
I really see no benefit of indexing and downloading every single plugin over just pointing to spigot cdn
raw sky
How are we meant to get all plugins for tab complete?
Oh you mean
We need to recognize already downloaded plugins
young knoll
Solution: don’t
I feel like tab completing 100k plus entities will make brigadier very unhappy

We have it already coded, we are scanning right now

I feel like tab completing 100k plus entities will make brigadier very unhappy

Shulker boxes are Directional https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/data/Directional.html
It's probably a bit better to create the block data and set it instead of the material
block.setBlockData(Material.WHITE_SHULKER_BOX.createBlockData(blockData -> {
((Directional) blockData).setFacing(BlockFace.EAST);
}));
(you can cache that BlockData if it's not dependent on some local variable if you want)

only WATER_CAULDRONS and SNOW_CAULDRONS are levelled though, lava cauldrons are not

For breakfast should I do a fry up or have a sandwitch?

The advantage is that Gradle can handle any inconsistencies across JDK versions in how exactly the JVM encodes the vendor information.
So basically you can also set which vendor you want to use
vendor = JvmVendorSpec.ADOPTIUM

Either works. instanceof will account for subtypes of wither skeletons though
There aren't any currently but maybe in the future

custom entities
hm
in that case
if something extends the nms classes would instanceof still catch it?
tender shard
yeah but custom entities will always have to return an existing EntityType anway, so they'd also just return EntityType.WITHER_SKELETON
but yeah instanceof would be better in case there would suddenly be any "subtypes" of wither skeletons, that's true

terminal velocity at 3.92 blocks/tick

it has always been a thing to omit the 1 when referring to java versions

// Calculate the initial velocity needed to reach the target
double initialVelocity = Math.sqrt((2 * 9.81 * (heightDifference + 0.5 * distance * Math.tan(Math.toRadians(45)))) / Math.sin(Math.toRadians(45)));

maybe? this also has an upwards angle of 45
i think its the block slide

My plugin calls an external API server but without doing it in a task is can be ...
call it async with scheduler then
tardy delta
everything is blocking, depends on how much blocking it is
bright jasper
idk how many of you guys have used rust but Actix actors are pretty nice, I think C# has orleans too, not sure if java has one
sacred wyvern
call it async with scheduler then
It's not always a repeating call. It's player initiated
remote swallow
you can still run singular tasks async with it
bright jasper
doesnt work
Here, even more updated. Default launch angle is 45 and if there is a wall in the way it calculates to hop over it
sacred wyvern
you can still run singular tasks async with it
kk any different then using BukkitRunnable? Sorry to ask I'm' picking up from a previous engineer and he used it.
There's one task that runs a lot to pull a message queue
remote swallow
pretty much the same thing
bright jasper
btw since that code is GPT generated, i have no idea why the hardcoded 9.81 is present. I assume its just standard gravity acceleration?
sacred wyvern
pretty much the same thing
Asynchronous tasks should never access any API in Bukkit. Great care should be taken to assure the thread-safety of asynchronous tasks.
Just confirming this means anything internal to Bukkit and not external API's

well... many things in bukkit are safe for async, e.g. using CHunkSnapshots

now it's going 45° into the other direction

Kk this doesn't really do much within the Bukkit except send chat messages to and from players.
The one that takes a while is the API call that loads a list of NPC Villagers into the Config file. The response on that request has thrown a warning that it's taking too many ticks
bright jasper

Replace this line:
double launchAngle = Math.toDegrees(Math.atan((initialVelocity * initialVelocity + Math.sqrt(initialVelocity * initialVelocity * initialVelocity * initialVelocity - 9.81 * (9.81 * distance * distance + 2 * heightDifference * initialVelocity * initialVelocity))) / (9.81 * distance)));
With this line:
double launchAngle = -Math.toDegrees(Math.atan((initialVelocity * initialVelocity + Math.sqrt(initialVelocity * initialVelocity * initialVelocity * initialVelocity - 9.81 * (9.81 * distance * distance + 2 * heightDifference * initialVelocity * initialVelocity))) / (9.81 * distance)));
💀
shocked if it works

where is that supposed to be? the code from your previous message doesn't have that two lines like you sent them
bright jasper
nvm change launchangle to ```
double launchAngle = Math.toDegrees(Math.atan((initialVelocity * initialVelocity + Math.sqrt(initialVelocity * initialVelocity * initialVelocity * initialVelocity - 2 * 9.81 * (heightDifference + distance * Math.tan(Math.toRadians(45))))) / (9.81 * distance)));
uhh a list already keeps order

guys who have a kind soul, help. you can make me a plugin radiation (you need to choose a world in which there will be a radiation strength from 1 to 9)
something like this: /red [world] [power].
power 1 = 1 damage in 60 seconds
power 2 = damage in 60 seconds and so on

How can I make a block not drop anything when broken?
tardy delta
this is pretty smart
man then wrote his own annotation processor to make it behave like a record but i believe it supports getters too
Generates ""value types"" classes that are packed into integer primitives of the most aproppriate size.
* It would be nice if Java didn't make crazy hacks like this necessary.```lol

Many ways
amber vale
Well thank you for this conclusive and helpful answer!
bright jasper

Oh this is pretty cool
Literally just regular byte representation of data. Quite literally a C struct
tardy delta
dunno how i would use it anyways
rotund ravine
Could ya like, open
Two different evengs
Can be used
Well
Three or more if paper is also included
BlockBreakEvent and BlockDropEvent is probably what you are looking for
amber vale
Yes
I am aware of that
But considering all of the information i've found has proven to be incorrect I'd love to hear an actually working solution
rotund ravine
?notworking

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.
amber vale
What do you want, my empty BlockBreakEvent?
For gods sake
Some people just choose to be difficult
kind hatch
But considering all of the information i've found has proven to be incorrect I'd...
Either listen for the BlockBreakEvent cancel it and set the block to air.
OR
Listen for the BlockDropItemEvent and remove the blocks from the list. (BlockDropItemEvent#getItems())
amber vale
Either listen for the BlockBreakEvent cancel it and set the block to air.

uhh
amber vale
Either listen for the BlockBreakEvent cancel it and set the block to air.

So uh, wanna hear a fun fact. When I cancel the BlockBreakEvent the block still drops it' drops (even though it does cancel the event properly).
I'd imagine BlockDropItemEvent is called first then or something
young knoll
BlockBreakEvent has a method to set it to not drop items
amber vale

looking at the internal code, im wondering why they dont use registries like minecraft does
