the loader does the loading, api is just an interface
#help-development

Elaborate, compatibility as in possibly supporting legacy etc?
dense goblet
you can mess with the loader all you want and people won't need to change how they interface with the api
as long as the api maps to the new loader correctly and vice versa
quaint mantle
does this server provide help for older versions such as 1.12.2?

I mean if the api is just interfaces why not shade it in? It’s plausible I don’t understand something here but yeah seems more logical to if they would have their api shaded
Yes space some people here do

my friend has asked me to strike a player with lightning when they kill a pig, but nothing happens so i'm not sure what's wrong, im not sure where to check for errors but nothing appears in the console log

if(event.getEntityType() == EntityType.PIG) {
if(event.getEntity().getLastDamageCause() instanceof Player) {
Player Player = event.getEntity().getKiller();

Block Block = Location.getBlock();
Player.getWorld().strikeLightning(Block.getLocation());

ok
worldly ingot
That being said, you could use that code in most Bukkit versions and it shoudl work lol. The only issue is this condition:
event.getEntity().getLastDamageCause() instanceof Player
last damage cause returns an EntityDamageEvent iirc
It will never be a player
quiet ice
Correct
quaint mantle
oh
worldly ingot
So you can get it, assign it to an EntityDamageEvent, check which event it was with an instanceof
quaint mantle
so
worldly ingot
If it was an instanceof EntityDamageByEntityEvent, cast it and work from there
worldly ingot
Suppose that would work as well. Yeah
worldly ingot

dense goblet
I mean if the api is just interfaces why not shade it in? It’s plausible I don’t...
I guess they could do that but that would introduce a disjoint between interacting with vanilla vs. interacting with other mods. Keeping the API as a mod introduces uniformity.
quiet ice
does `!=` work as a "is not" in java?
Just beware to not use it when #equals can be used (in this case it cannot be used because you cannot detect null that way)

oh ahtsdhgyifd
dense goblet
How would it introduce a disjoint? Or like could you elaborate just curious heh
Well fundamentally there would be a difference, partly in implementation but also partly in perspective. If you interface with vanilla through a mod, it "feels" the same as interfacing with, say, Tech Reborn. It allows you to detach from the idea that vanilla is the "base game", which imo is a good thing because you ideally want to keep your mod logic pretty independent (to ease with updating etc)
quiet ice
Basically do NOT use == and =! for everything that extends java.lang.Object
Enums and other singletons (such as threads) are an exception there though
ivory sleet

brittle nova
It's a very specific question but I hope somebody can help me. So I want that there are particles on a location as long as the location is marked like pos1 or something. Bukkit.getScheduler().runTaskTimer(plugin, () -> { if(particlesActive){ PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles(Particles.HAPPY_VILLAGER, true, location.getX() + 0.5, location.getY() + 0.5, location.getZ() + 0.5, 0.01f, 0.01f, 0.01f, 0.01f, 5); PlayerConnection connection = ((CraftPlayer) player).getHandle().playerConnection; connection.sendPacket(packet); } }, 20, 20); This is what I have till now
wraith rapids
that's not a question
quaint mantle
the code still doesnt work after
- if(event.getEntity().getLastDamageCause() instanceof Player) {
+ if(event.getEntity().getKiller() instanceof Player) {
still no errors, or im not looking in the right place for them
brittle nova
that's not a question
what is it then?
wraith rapids
it's a statement
brittle nova
So...?
wraith rapids
ask a question
brittle nova
ask a question
How can I make that particles spawn on a location as long as the location is marked like pos1?
wraith rapids
you can store the bukkitrunnable and put it in a Location -> runnable map
and then cancel the runnable once you remove pos1 from the map
brittle nova
if(particlesActive){
PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles(Particles.HAPPY_VILLAGER, true, location.getX() + 0.5,
location.getY() + 0.5,
location.getZ() + 0.5, 0.01f, 0.01f, 0.01f, 0.01f, 5);
PlayerConnection connection = ((CraftPlayer) player).getHandle().playerConnection;
connection.sendPacket(packet);
}
}, 20, 20);``` That's what I have till nowalternatively, you can check if a set of Locations contains pos1 in it every time you spawn a particle, and cancel the runnable if it doesn't
why are you using the protocol and nms for particles though
brittle nova
why are you using the protocol and nms for particles though

How do I get all the information from my MySQL table, in this case, all the players registered?
fringe escarp
Wouldn't that just be something like SELECT * FROM <table_name>?
I've got a quick question too: Do I understand correctly that Chat API stuff to make clickable chat messages are not part of the Spigot API? So I have to depend on BungeeCord which is like 14 MB just for that feature? :c
floral flare
I did, but how do I store it in a variable?
floral flare
It becomes like an object, there is no way to reverse it
ivory sleet
It’s shaded in both bungeecord and spigot
fringe escarp
I did, but how do I store it in a variable?
I'm not familiar with how you access the DB from code and I probably can't help you with that because I use MongoDB for my Minecraft stuff and SQLite at my workplace, but I'd imagine you can cast the object? You'll definitely find info on that online.

heavy island
Is the singleton design pattern a bad idea in java? I've got a class that I need to pass into many other classes because it's the general handler for a filter in my plugin. There should never be two instances of this class because if there were, there would be two different filters with differing contents.
ivory sleet
Idk I avoid singletons because it makes your program hard to unit test and it may also tightly couple your code which can be indefinitely hard to work with
Or maybe I should say static singletons
heavy island
I'm guessing that my issue is that the scope of the class is too wide.
ivory sleet
Wym?
dense goblet
is it ok/possible to save data in the world folder?
dense goblet
ig it doesn't matter much because I would store it per-chunk and overwrite it if a chunk is newly generated
ivory sleet
Oh yeah
dense goblet
but still it would take up space uselessly
so yeah using the world folder seems like the most sensible option
ivory sleet
Yeah it would remove the awkwardness for you a bit
heavy island
it's a class that at first only contained a bit of information about something but grew to contain so much information that it has to be passed to many other classes in my plugin. I think my issue is that I made the scope of the class too large and I'm struggling with handling the places it needs to be passed because of it.

How is use of proper design principles such as SOLID not needed in Spigot plugins?
ivory sleet
Benz arguably you don’t need to create an interface (dependency inversion) for everything such that you depend on high level abstraction instead of low level for instance.
simple summit
I made an interface to define my "big bag of crap" API and have my plugin implementation implement that interface, then I pass that around - because most everything needs the plugin anyway
and within my various classes i use a decoupling strategy to make testing easier
ivory sleet
SRP is probably something which is more essential to follow. But then for instance we have liskov substitution principle which if you declare a field to have the type HashMap instead of Map won’t make your entire application break but yes it’s generally good to follow (If S is a subtype of T then it should be substitutable with any subtype of T)
west berry
Why is my .conf doesnt work with multicraft jar file...?
simple summit
for the decoupling strategy i define an interface (within a command class for example) called IDecoupler then i also create a class Decoupler implements IDecoupler - then i have 2 constructors - one that takes my plugin and another that takes an IDecoupler. I can then either make a stub implementation of IDecoupler in my tests or use mocks
odd gulch
Dependency inversion is far from simply introducing interfaces. I just disagree with not conforming to conventions simply because the piece of software you are developing is a Spigot plugin.
west berry
it doesnt make the server bungeecord
ivory sleet
I’m not saying because of spigot we shouldn’t follow solid but I would argue that it might not be the most vital thing you should crucially pay attention to.
odd gulch
Also you don't have to summarize the principles. I know what they are and they are easy to look up. I just wanted to point out that just because you are developing a plugin doesn't mean you shouldn't follow proper conventions.
simple summit
Oh, and my 'decoupler' wraps about every call to my plugin big bag of crap
odd gulch
Down the road no matter what you throw together you will thank yourself for maintaining proper conventions and consistency. But I do agree that it is a cost/benefit issue.
simple summit
I avoid singletons and global/static state - makes for brittle code over time
static helpers are fine - so long as they have no side effects (only take action on the given inputs and output)
ivory sleet
Of course it’s significantly better if you follow those. However as I stated before it may not be needed to strictly follow it. In my opinion getting something to work should be the primary priority. Then after that it may be beneficial to engineer what you’ve done such that it follows solid more strictly I guess if you wanna extend it later (:
odd gulch
That I can agree with. Refactoring is a crucial part if you want to be agile instead of rigorously planning and designing your software.
simple summit
+1 - don't worry about doing it right until you are doing the right it
ivory sleet
Yeah absolutely.
odd gulch
Loooots of prototyping xd
simple summit
That's coming from someone with 16 years industry experience as a software developer here... just saying
ivory sleet
Hehe
simple summit
Was quite the revelation when I reconciled "test first is the only right way to create software" with my answer to "why don't i test first" being "because i can't - because IDK what i'm building yet"
Just NEVER allow your prototype / exploration code to become the delivered solution
stop yourself once you reach the point of knowing what you need to do and how to do it
That's the moment to go back and do it right
odd gulch
Behavior Driven Development really gave me the right reasoning for TDD. Write tests for the behavior you seek next.
simple summit
Indeed BDD is my preferred flavor of test first
works better with the human mind than "what do i test next (that doesn't yet exist)
anyway, back to refactoring my projects to share maven modules lol
It's funny because with all the experience I have - I've never touched maven before working on spigot plugins cuz the big tech companies i've worked for always do things their own way and don't generally use standard tools :/

Anyone know how to listen for any event ?
ivory sleet
It’s avoided but I guess just register an event handler method for every event class which isn’t abstract
simple summit
as in wild card? like listen for them all? it's a reflection tick
heavy island
isn't there a saying about refactoring that somewhat says that you should be refactoring for at least the same amount of time you're writing new code?
west lance
Because
ivory sleet
(Could use EventExecutor) to do it more convenient
west lance
Bukkit.getPluginManager()
.registerEvent(
Event.class, bukkitEventListener, hookPriorityToEvent(priority), bukkitEventListener, plugin);```If I do that
It errors of HandlerList not found
ivory sleet
Yes of course
heavy island
there's no way to quickly listen for every event without registering every event
simple summit
ya, you can't register for the base type
heavy island
afaik, at least
simple summit
i'll post a snip of how i do it
ivory sleet
You could use smtng like dgraph or whatever it’s called
To loop through every class and then check if isn’t abstract and is a subclass of Event
Then register an event executor for it (:
west lance
Things is while using EventExecutor then I cannot do with EventHandler priority
simple summit
yup
ivory sleet
Yea you can
ivory sleet
PluginManager#registerEvent takes one with priority
simple summit
I copied that from somewhere at some point
ivory sleet
Yes? Obviously
west lance
So you cannot do that using EventExecutor & Listener only
ivory sleet
Wat
Do smtng like Ross but have an interface/class that implements both Listener and EventExecutor I guess and use that then in registerEvent?
west lance
I do have that
ivory sleet
So what’s the issue
west lance
Yea well one now that is getting the classes
quaint mantle
if I wanted to spawn an armorstand with a custom head texture from say Minecraft-Heads, how would I do this? Im only stuck on how to put a custom skull on the armorstand
west lance
Cause I gotta hook into each event for each priority
That's damn a lot of listeners lol
Oh well
simple summit
There's only 2 ways to do it... 1 - the long way where you make a handler for every event type - or 2 - you use reflection like i posted
heavy island
just listening to an event isn't going to hurt you. All that really matters is what you're doing in your listeners.
simple summit
ya - there is no "every event" handler - that's not how the event system was built
west lance
I'm forwarding them into my system
odd gulch
Does the 2nd last reply here not work for what you are doing?
https://www.spigotmc.org/threads/listen-to-all-events-easily.235870/
I realize it is very old
heavy island
some events can be fired many, many times in a single second. Make sure that your initial checks are quick, otherwise you're going to lag the server pretty badly.
sharp moat
I got a question, prob best for staff to answer but if I release a plugin, but someone else already stole my name like 5 years ago, do I have to rename it?
ivory sleet
Benz I believe every event must fire at least once if HandlerList#getHandlerLists should give a collection of all handler lists as classes can come and go dynamically right?
west lance
I just check if there's the listener in a map by the event class name
That shouldn't slow down much
heavy island
are you trying to make a custom listener system?
simple summit
if I wanted to spawn an armorstand with a custom head texture from say Minecraft...
I assume you mean using the Spigot API... it's complicated - there isn't a ready solution, it's reflection heavy and you have to build a player profile and such
ivory sleet
Not really

easy enough TBH, just figured i'd try to be lazy
west lance
If you're lazy, use flat
simple summit
hard part is getting the layers dynamically rather than just hard coding them
then ppl will bitch at me that it's too non-vanilla
west lance
Lol
simple summit
IKR
west lance
Well just have a chance of bedrock at 0-3
then if it's chance met, put bedrock if not stone
simple summit
until world gen changes, and there's top bedrock in the nether
it's easy enough to shuffle the layers on chunk create
just have to find a good enough way to future proof it
simple summit
i was thinking of "learning" the layer heights by doing a chunk scan - but ya
west lance
I guess just get the sections array lenght
simple summit
like the first time a chunk is generated if the plugin doesn't know where that world puts bedrock it searches for it then remembers
west lance
But thing is
simple summit
but then once world heights increase - any old chunks will be different than new ones and crap
west lance
I have high doubts that they will have same chunk structure
They'll probs rewamp the whole chunks system
simple summit
well, chunks / blocks will still be exposed in the spigot API 😛
west lance
Well spigot will have to adapt tho
simple summit
I'm thinking of just hooking the new chunk event and mutating the chunk just after it has been generated instead of trying to directly modify world generation
anyway, i'll get'er done one way or another

that sounds horrible
imagine loading a new chunk and then all the sudden every block in it changes

still would affect mining but I see

Material sellitem_material = sellitem_seller.getInventory().getItemInMainHand().getType();
ItemStack[] contents = sellitem_seller.getInventory().getContents();
int counter = 0;
for (int i = contents.length; --i > -1;) {
if (contents[i] != null && contents[i].getType() == sellitem_material) {
counter += contents[i].getAmount();
}
}
So this code ^^ gives me the total amount (counter) of items matching the item material of the item in hand.
How do I do the exact same thing except matching all metadata of an ItemStack, except amount?
simple summit
The players location will be at the "pre respawn" location when the event is fired.
So i check if they were in the end, on the central island, and look at if their feet are in an end portal block

and here's how I detect a respawn due to exiting the end via exit protal

so this is how i determine if they are respawning due to exiting the end, or if they really died
mortal hare
basically whenever he eats, increase his velocity maybe
tacit drift
and consistent
west lance
That actually is 199iq
tacit drift
i had a player saying that he has a noslow bug 🤣
west lance
It always slows down for the same amount
vital ridge
and here's how I detect a respawn due to exiting the end via exit protal
``` ...
extraInfo = (extraInfo != null ? "; " : "") + "exit-end-via-portal";
west lance
so you can hardcode the amount of velocity
vital ridge
I dont understand that part
mortal hare
the thing is it would allow to autosprint
vital ridge
and the MoreMath
west lance
AntiCheat what's that
I mean
You should get his velocity first of all
To see if he's moving or not
simple summit
That's just code outside the snip i took - MoreMath is my own utility library the function used is just as described 😛
return min <= value && value <= max;
}```yes, but still, lets say he started eating before he stopped
tacit drift
but i still think that he was hacking
tacit drift
or is using a bugged client
west lance
You cannot just run and bow
mortal hare
that's impossible
cinder thistle
oh dear god
tacit drift
told him to reproduce the bug
mortal hare
that's possible only from clientside by sending invalid packets to the server
tacit drift
he said that he can't
west lance
Lol
tacit drift
we are on 1.8
tacit drift
and he was using 1.8
mortal hare
since i don't see any for couple weeks
tacit drift
taco
west lance
Just god dammit use an anticheat
tacit drift
we do
west lance
And you'll see invalid packets
west lance
ncp damn
mortal hare
better, use protocollib, and code your own packetlistener which checks what packets his client sends to the server
west lance
That's a high quality anticheat
mortal hare
and build your own patch
tacit drift
anyway, thanks for the help 👍
vital ridge
and here's how I detect a respawn due to exiting the end via exit protal

is this needed?
seems like no
😄
cinder thistle
That's a high quality anticheat
so great, catches every haxor
simple summit
No, that's just the point in the code you would know that they respawned due to exiting the end 😉
vital ridge
Okay but
the locations you check
in between
Why is this necessary?
you are getting like the center?
of the end
where the portal
usually forms?
simple summit
I'm checking that the player is #1 respawning from somewhere in the end #2 they were on the center island (really that +/- 100 check could be +/-10) and #3 that they were standing in an end portal block when they respawned
the players location inside the player respawn event handler is their location BEFORE they actually respawn - aka where they 'died'

can anybody help whenever im following this turoial and i double click on the build tools.jar folder it only makes 1 extra folder however it should be making loads of other folders here the tutorial btw : https://youtu.be/clGVQXsVdiI

vital ridge
I mean
&& MoreMath.isBetween(playerLoc.getX(), -100, 100)
&& MoreMath.isBetween(playerLoc.getZ(), -100, 100)
this is more like
special ensuring
i dont think its like too necessary
but its good
cursive trellis
can anybody help
west lance
Hmm guys how does one loop thru Path children?
simple summit
It's cheaper to check some floats than query blocks (well, that was my thought anyway - IDK if it's right)
simple summit
But you are correct that it is not strictly necessary to check that the player is near the exit portal location before seeing what they are standing in to decide if they took an end portal
vital ridge
Ill use it anyways
but ill split them apart
like remove the &&
since i need to check a real respawn event
aswell
so i can just add else

Material sellitem_material = sellitem_seller.getInventory().getItemInMainHand().getType();
ItemStack[] contents = sellitem_seller.getInventory().getContents();
int counter = 0;
for (int i = contents.length; --i > -1;) {
if (contents[i] != null && contents[i].getType() == sellitem_material) {
counter += contents[i].getAmount();
}
}
So this code ^^ gives me the total amount (counter) of items matching the item material of the item in hand.
How do I do the exact same thing except matching all metadata of an ItemStack, except amount?
silver shuttle
any ItemStack data like displayname etc
mortal hare
by lore?
silver shuttle
basically just count the amount of items matching ItemStack
eternal oxide
isSimilar() shoudl compare all bar amount
mortal hare
or compare the itemstacks
silver shuttle
so if the itemstack is a diamond with amount = 1 and you have a stack of diamonds in your inventory counter = 64
mortal hare
like he's saying it to you
silver shuttle
I tried this
but it didnt work
returned 0
and sellitem_sell_item has Amount of 1
silver shuttle
okay hold n
eternal oxide
silver shuttle
so like this?
simple summit
looks right enough to give it a run - ya
simple summit
GG 😄
simple summit
== and != almost never work - except for checking for null
This type of equality checks that the objects are the exact same INSTANCE
not if they contain the same information
silver shuttle
yeah I used it for same material before
simple summit
ya, material is an enum - there is only ever one instance of each material type so == works there just fine
simple summit
== works fine for integers too - but not so well for floating point numbers (float/double)

I didnt use your method but
I found a better one
Not a method just a simple check
you check if players world is equal to end
aka the world he enters from
then you run a task later
and execute your code there, that worked fine for me
But thanks for the help tho!

Does this work?
String itemsdbstring = String.valueOf(item).replace("\"", "\\\"");

How do I do that
it doesnt work

Just wondering, why is my code for playing audio from a resourcepack having a bit weird behavior:
for (final Player p : players) {
p.playSound(p.getLocation(), "audio", 1.0F, 1.0F);
}
Suppose the resourcepack has already been sent to players and the resourcepack is valid.
Running this first time, the sound plays. After that sound plays. I run it again. The thing is that for some odd reason, it won't play the audio for clients on the second play. However, if I just execute the loop again the audio will play properly.
Does anyone know how to fix this?
I swear that is the only place I am playing sound
