They are two quite different languages
and before you run in to problems with your string comparisons use .equals instead of ==

That's not the entire issue here
The problem is they're trying to call getState on their gameManager variable
Which is never initialized anywhere
and there for is null
The game state is being set in other methods (which they've said are being called... I do agree that initializing state in the constructor is a good idea)

I think the main problem is that the lines of text you are writing, make no logical sense to you.
You need to stop what you are doing and start with something extremely basic, to understand how a computer actually runs code.
junior pewter
well, i guess i'll go sleep now and tomorrow start with basics...

Also a game manager is probably not the class you wanna store your state
A game manager is supposed to handle your games
A game is what I'd say would hold a state
junior pewter
game manager is supposed to manage game generally - states, etc...

I feel like lambdas should be kept to a minimum anyways. So one liners, otherwise create an actual method and reference it. 🙂
mortal hare
i like how lambda expressions that are present in kotlin std are mostly inline
so they cost nothing when compiled

For me it took a while to accept it as a keyword

For a tiny expression like it.toMap().entries or something it's fine ig

the only thing is weird is the destructuring objects

my beloved

i mean why not destructure by property name
why by order
_ is ugly
my precious clean syntax sugar
blazing ocean
i mean why not destructure by property name
Because then you can't rename your variables
blazing ocean
`_` is ugly
use _epicUnused instead, please don't just have a bunch of _s
mortal hare
add TS like destructuring propertyName: newPropertyName which compiles to smth like val newPropertyName = propertyName
blazing ocean
no

What i dont like is returning values from lambdas. It makes their scope ambigous. Something like
ints.filter {
val shouldFilter = it > 0
return@filter shouldFilter
}
yea also that
but you can use anonymous functions
which works the same as lambdas but use proper return functionality
blazing ocean
What i dont like is returning values from lambdas. It makes their scope ambigous...
You could also just .filter { it > 0 } here but sure
and you can label your lambda
ints.filter filterNotZero@ {
val shouldFilter = it > 0
return @filterNotZero shouldFilter
}
This is very useful when you're iterating over multiple lists

No idea why you wanna label lambdas probably makes sense it kotlin tho

?? lol
blazing ocean
not an annotation
dry hazel
it's for returning on a different level if you have multiple nested lambdas
lilac dagger
Oh
This is not possible in Java as far as I know
So similar to label: for loops in Java
dry hazel
also for referencing the lambda receiver of a different level
lilac dagger
But I don't see myself nesting

there are some places where I've used it but not very often

This is my function for serializing PlayerCourse class.
https://paste.md-5.net/exinefeyaf.js
I'm putting courseFeatures in the map, which is List<CourseFeature>, note that CourseFeature is my custom class. Since its my custom class, it implements ConfigurationSerializable and also it's own serialization method.
https://paste.md-5.net/bacijemihu.js
The thing is I'm somehow serializing the CourseFeature incorrectly. It failes to serialize and throws an error in the console telling me that object serialization failed.
lilac dagger
Course status must be also serializable
vital ridge
Its an enum
And it doesnt have to be, I already tested by setting it and updating the pdc after that
no errors
lilac dagger
Well the error might help you out
vital ridge
Worked perfectly, I've only gotten errors when adding coursefeatures to the list, it fails to serialize them
vital ridge
Yes
it is
This is the error
@Override
public @NotNull PlayerCourse fromPrimitive(@NotNull byte[] primitive, @NotNull PersistentDataAdapterContext context) {
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(primitive);
try {
/*
private UUID owner;
private String name;
private CourseStatus courseStatus;
private int size;
private List<CourseFeature> courseFeatures;
*/
BukkitObjectInputStream bukkitObjectInputStream = new BukkitObjectInputStream(byteArrayInputStream);
Map<String, Object> playerCourseMap = (Map<String, Object>) bukkitObjectInputStream.readObject();
UUID owner = UUID.fromString(String.valueOf(playerCourseMap.get("owner")));
String name = String.valueOf(playerCourseMap.get("name"));
CourseStatus courseStatus = CourseStatus.valueOf(String.valueOf(playerCourseMap.get("courseStatus")));
int size = (int) playerCourseMap.get("size");
List<CourseFeature> courseFeatures = (List<CourseFeature>) playerCourseMap.get("courseFeatures");
return new PlayerCourse(owner, name, courseStatus, size, courseFeatures);
} catch (IOException e) {
throw new RuntimeException(e);
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
}
Map<String, Object> playerCourseMap = (Map<String, Object>) bukkitObjectInputStream.readObject(); this returns null
sly topaz
BukkitObjectInputStream 💀
lilac dagger
The class is not bad ^
sly topaz
also, use a try-with-resources
vital ridge
@Override
public @NotNull Map<String, Object> serialize() {
Map<String, Object> serializedMap = new HashMap<>();
String type = "";
if (this instanceof CheckPoint)
type = "checkpoint";
else if (this instanceof SpawnPoint)
type = "spawnpoint";
serializedMap.put("location", location);
serializedMap.put("type", type);
return serializedMap;
}
so this method needs to be a constructor?
In CourseFeature class?
No waitr
you said
lilac dagger
The reverse of it actuwlly
vital ridge
deserialize
lost matrix
At that point its time to shove spigots serialization system in the bin and use an actual serialization library like Gson or Jackson.
Storing ConfigurationSerializables in a PDC is def not the way to go.

You need a deserialize constructor
So ill just transfer my deserialization method to a constructor?
How would I return the deserialized obj?

Isn't all memory in bytes?
Nah mine is terrabytes 💪

The deserialization is to give you back the object
Serialized is to pack up your object
You need both

I see but in order to give back the object ill need to return the object
young knoll
RAM has ADHD
vital ridge
I cant return anything from the constructor
young knoll
That’s why we need SSDs/harddrives
blazing ocean
trueee
remote swallow
I cant return anything from the constructor
the constructor returns the object
whatever you set in the deserialize method you would set in the constructor
you dont need a constructor either
pick 1 and use it
remote swallow
is it static
vital ridge
Yes
remote swallow
?paste ur full class and any errors
undone axleBOT
remote swallow
on seperate pastes
remote swallow
that is just a lot of jank
you cant return an instance of the abstract course feature
remote swallow
its expecting a course feature not a subclass
vital ridge
Oh shit frl?
Cant i just return a subclass anywas
anyways*
Since its pretty much the same as coursefeature
Okay sht I think im fking up the basics of java now
worldly ingot
Maybe I'm missing it but I haven't seen you register the actual serialization anywhere
vital ridge
I did register it in my main method
worldly ingot
Okay just making sure :p
Generally we do it in static blocks in the plugin's init, if I'm remembering correctly
vital ridge
I did it under onEnable()
worldly ingot
Yeah that's probably fine
vital ridge
you dont need a constructor either
But like I assume spigot just user reflection to run my method
public static CourseFeature deserialize(Map<String, Object> serializedMap) {
ConsoleManager.message(ChatColor.RED + "USING THIS METHOD!!!!!");
String type = String.valueOf(serializedMap.get("type"));
Location loc = (Location) serializedMap.get("location");
if (type.equals("checkpoint"))
return new CheckPoint(loc);
else if (type.equals("spawnpoint"))
return new SpawnPoint(loc);
return null;
}
my debug message here never was ran
I cant find it in console
remote swallow
But like I assume spigot just user reflection to run my method

because that's just the example
alex provides you with a <relocation> for you to use in the guide
Do you kinda understand how the xml document is like a tree? (if you've done HTML before it's very similar)
novel frost
Yeah, so xml is similar, except it's data
tidal fog
gotcha
novel frost
so instead of ripping out the "section" tag that has an article, you need to merge the structure, and replace it with the "section" that you need
in this case you are subsituting the relocation for the one provided in the guide
and adding a plugin to your plugins section
"phase" package, is the part of the build that bundles up all the classes
tidal fog
i didnt understand any of that
novel frost
and the goal 'shade' is the step of that, which is copying classes from one classpath to another, and is provided by the plugin you just added
sorry was trying to use html as an analogy when I was talking about 'section' tags
tidal fog
ive done html (i made snake in it) i dont know much about it
novel frost
Yeah it's all good

hey guys im trying to make a server where armor trims give effects, like silence would give strenght 2 or rib would give fire rezistance, and when you take the armor off the effects go away.
but like so that i can have 4 effects at once by wearing armor
can anyone help me pls
novel frost
anyway, relocating is basically scanning your classes and renaming the packages
<pattern>org.codehaus.plexus.util</pattern>
<shadedPattern>org.shaded.plexus.util</shadedPattern>
means that it turns org.codehaus.plexus.util into org.shaded.plexus.util in your code. so by renaming the package, you 'adopt' the code into your codebase, so other plugins can't accidentally use it unintentionally. which means you don't need to worry about version conflicts etc.
<excludes>
<exclude>org.codehaus.plexus.util.xml.Xpp3Dom</exclude>
<exclude>org.codehaus.plexus.util.xml.pull.*</exclude>
</excludes>
in the example is showing how to exclude a package of classes from being scanned, presumably because if you changed them, stuff would break

can anyone help me pls
Get the armor trim data from the item

Unironically for the dead basics I'd reccomend just using Google and chatgpt. Now when I say dead basics with chatgpt I mean it your questions should be like how do I take user input or how do I loop over a list vs how do I write my entire project
If you stay dedicated you'll beable to write pretty much anything you want within a few months
It won't be easy but totally worth

Hi there, I am having some issues with my NPCs I am creating. Whenever I spawn the npcs they are located exactly on top of the player, not at their set positions, their heads are rotated correctly.
This is my code:
public void spawn(Player player) {
CraftPlayer craftPlayer = (CraftPlayer) player;
ServerPlayer serverPlayer = craftPlayer.getHandle();
ServerGamePacketListenerImpl ps = serverPlayer.connection;
MinecraftServer server = serverPlayer.getServer();
ServerLevel level = ((CraftWorld) player.getWorld()).getHandle();
GameProfile profile = new GameProfile(UUID.randomUUID(), "npc");
profile.getProperties().put("textures", new Property("textures",
texture, signature));
ServerPlayer npc = new ServerPlayer(server, level, profile, serverPlayer.clientInformation());
npc.connection = new NetworkHandler(server, npc, CommonListenerCookie.createInitial(profile, true));
npc.setPos(location.getX(), location.getY(), location.getZ());
npc.setCustomNameVisible(false);
ServerEntity npcServerEntity = new ServerEntity(serverPlayer.serverLevel(), serverPlayer, 0, false, packet -> {
}, Set.of());
SynchedEntityData synchedEntityData = npc.getEntityData();
synchedEntityData.set(new EntityDataAccessor<>(17, EntityDataSerializers.BYTE),
(byte) (0x02 | 0x04 | 0x08 | 0x10 | 0x20 | 0x40));
ps.send(new ClientboundPlayerInfoUpdatePacket(Action.ADD_PLAYER, npc));
ps.send(serverPlayer.getAddEntityPacket(npcServerEntity));
ps.send(new ClientboundAddEntityPacket(npc, npcServerEntity));
ps.send(new ClientboundSetEntityDataPacket(npc.getId(),
synchedEntityData.getNonDefaultValues()));
ps.send(new ClientboundRotateHeadPacket(npc, (byte) ((location.getYaw() %
360) * 256 / 360)));
ps.send(new ClientboundMoveEntityPacket.Rot(npc.getBukkitEntity().getEntityId(),
(byte) ((location.getYaw() + bodyOffset % 360) * 256 / 360),
(byte) ((location.getPitch() % 360) * 256 / 360),

fallen patrol
I am sorry, I'll add some comments
novel frost
that's a heck of a lot of NMS and packet hacking going on
fallen patrol
Is there a way to combine things then? :o
fallen patrol
no comments 😔
What it comes down to, I make a ServerPlayer and use .setPos, but somehow even tho all the values are filled, they don't go to that spot but instead will spawn on top of the player
novel frost
npc.setPos(location.getX(), location.getY(), location.getZ());
where is location defined?
fallen patrol
In itself, it's an entire class, perhaps a way I could share the entire class without spamming the discord? A pastebin or anything?
novel frost
Also, I'd set a breakpoint right after that, and double check npc.getPos is right
novel frost
I'd then scan through the packets you are sending right after that, and compare them to https://wiki.vg/Entity_metadata#Entity:~:text=minecraft%3Afishing_bobber-,Entity Metadata Format,-Note that entity to make sure your getNonDefaultValues isn't stealing the position off the player
novel frost
This is my BaseNPC class
Yeah location isn't get set anywhere there, so it's whatever is extending it, or maybe the getNonDefaultValues
if EVERY investigation fails, I'd try changing the timing up, or comparing it to normal entities
eternal oxide
he is using Lombok
so he sets it in the all args constructor
show your code to spawn this npc
fallen patrol
Yea the location is set in an class which extends the base
novel frost
ServerPlayer npc = new ServerPlayer(server, level, profile, serverPlayer.clientInformation());
This looks like it's cloning a player here, so it's probably cloning the location right in the constructor
eternal oxide
no
he uses setpos so he is using teh location field
his fault is in calling his class
novel frost
nm, didn't realize the snippet above was the same class in the paste
fallen patrol
public static void addNpcsToPlayer(Player player) {
npcPlayerActions.put(player, new ArrayList<>());
for (BaseNpc npc : NpcData.npcs) {
NpcPlayerAction hubPlayerAction = npc.spawn(player);
npcPlayerActions.get(player).add(hubPlayerAction);
}
}
I mean this is where I execute the spawn() function
eternal oxide
where do you create the npc instances?
fallen patrol
It's being done on server start up, just has a list of classes that are extending by the base. Like https://pastes.dev/dg1Vyq0NNh
eternal oxide
so all spawn at new Location(Bukkit.getWorlds().get(0), -16.01, 64.06, -21.5, 13, 20),
novel frost
So does Timmy also spawn on the player?
eternal oxide
oh I see
your npcServerEntity uses the serverPlayer and not npc in its constructor. Ryan was correct
eternal oxide
you setPos on npc, then use serverPlayer instead
novel frost
not really the constructor, but I was in the ball-park
I was just trying to trace where the players location could have been poisoning stuff
fallen patrol
Thank you guys, it works!
Yea the code is a bit messy too, got some good improving to do
novel frost
if it makes you feel better Mau, I was stuck for 3 days on the following.
I felt REAL silly afterwards
also came down to how messy the code was, simplifying it for a friend who was new at coding, it becomes very obvious

Themeing wise, I'd love to experiment with something that exposes public method usage (within your project and classes only) with different fonts, https://monaspace.githubnext.com/#learn-more
But I think I'd need to swap to VSCode, as intellij's themeing is surprisingly limited.
having Comic Sans ish font, for anything I expose as API, would be a good reminder to not expose it by accident
and when I was doing C# dev, being able to highlight methods that were considered internal, would have helped to tell at-a-glance where user input validation was leaking

why the hell i get this error:

like the victim will containkey damager?
fallen patrol
How did you initiate your PlayerDamageListener? The error is about damageMap being null, not anything related to the behaviour of th emap
fallen patrol
Your class PlayerDamageListener, where do you create an instance of it
vague dawn
nowhere
fallen patrol
Making a class implement Listener doesn't immediately make it a listener, where do you register your listener
vague dawn
in main class
fallen patrol
Can you show the code
fallen patrol
Yea the whole code
vague dawn
give me a minute
hybrid spoke

fallen patrol
I mean given you're using a singleton for you damagerMap, you probably don't need to pass it through your entire code, you could just do inside you PlayerDamageListener a DamagerMap.getInstance() inside the constructor and remove the parameter
But whatever you're passing onwards into the function is null
hybrid spoke
hey, going for another help...
yeah well
you never call getInstance
so damagerMap is always null
since you only instantiate it there

i dont quite get why you wrapped a map in a map object but anyways

hybrid spoke
well i am not that good, still learning and its mostly first time using somethin...
i mean, you have everything. you just need to call DamagerMap.getInstance() somewhere and use the returned instance
vague dawn
can i call it inside the PlayerDamageListener like this:
hybrid spoke
yes but that wont fix your problem since you dont use that instance but a field of your main class instead
private DamagerMap damagerMap; to private final DamagerMap damagerMap = DamagerMap.getInstance();
vague dawn
in main?
hybrid spoke
where i linked it
vague dawn
okey
fallen patrol
hey, going for another help...
Where you do this.damagerMap = damagerMap you could do this.damagerMap = DamagerMap.getInstance() and you can remove the parameter from the constructor
hybrid spoke
<https://github.com/Nergl02/KnockBackFFA/blob/main/NerKubKnockBackFFA/src/main/j...
but that being said you dont need the getInstance method in DamagerMap. you can just instantiate it right away.
private final DamagerMap damagerMap = new DamagerMap();
that would be the better approach
and then you pass it to where you need it, a la PlayerDamageListener
vague dawn
Unless he wants to use it elsewhere
no
hybrid spoke
thats what DI is for
best to lead them away from static abuse before they even get to it
vague dawn
when i remove the getInstance method in DamagerMap i get this error:
i guess i need it in DamagerMap class
hybrid spoke
the singleton pattern is a bad pattern with only little of justified usecases
hybrid spoke
when i remove the getInstance method in DamagerMap i get this error:
yes, now you need to instantiate the object
create a new one

All plugins compatible with 1.21 are compatible with 1.21.1
chrome beacon
NMS version changed
It did not

For reference 1.21.1 just patches two bugs and added two languages

Ye it was a server crash bug or something wasn't it

do you know if this still the case
it seems that previously default impls on interfaces produced static class inside an interface, instead of utilizing default keyword inside jvm

I've made a plugin that uses custom heads for some of the items. when testing this on a test server of the same version (1.21.1) I get no errors. when we have moved it over to our main server I am getting this error. does anyone have an idea as to what this could be caused by ? \https://pastebin.com/5XP1KQJd

I want to get into plugin development and I know you probably get a lot of new people who just beg for help and I may seem like one of them but I am making a mistake during just setting up a basic plugin somewhere and cannot for the life of me find what I am doing wrong. If someone could join me in general-1 vc to help me out that would be great.
Cheers,

trying to fix a bug in viaversion

nvm I found a fix (im dumb and didn't realise name for the plugin.yml auto set to paper-plugin.yml which was causing it to not get included in the plugin so I renamed it)

I found the packet just for it to be spitting nonsense/garbage, fun
why must it be a string of only the color codes? wtf wheres the actual text
pliant topaz
theoretically you could maybe find a solution in newer versions of viaversion's code
maybe it works for your version, maybe not
obtuse hedge
its in the 1.12->1.13 conversion
i tested 1.8-1.12 and 1.13 is when the issue appears and lasts till 1.21 (latest)
packet id 0x45 in the 1.12.2 protocol, Update Score
which creates the lines and sets the text
I print out the data from that packet
and the text is just color codes
i've also printed out the data from the objective ones too
none it matches what i see ingame
theres 10 prints of SET_SCORE display name which is the same amount of lines there is on the scoreboard but the data it prints is just wrong

is there a way to stop a block placing using PlayerInteractEvent?
smoky anchor
just cancel the event
torn bough
I'm trying to get the players current World id that way I can use it to save their Location
Should I really just loop through each getWorlds() and check the name until it matches to get the id of the current world in the array? Or is there a better way? (almost like toName, but I want toInt)
smoky anchor
player.getWorld should exist
torn bough
Doesn't that return a World?
smoky anchor
oh world ID
That is.. not a thing ?
torn bough
So I later can do Location (getWorld(here will be the id), -, -, -)
smoky anchor
you mean UUID ?
torn bough
Because right now I have it default to getWorld(0)
And that works but that will always teleport to the overworld, not nether or end
And if I change it to getWorld(1), then it'll work
So I'm trying to convert the players current world to a int
smoky anchor
Ye I don't think that is how you should manage the worlds
Give me a minute
I'm in a meeting at work lol, I'll have to re-read this so I can give proper answer lul
(or get sniped by the big man)
sullen marlin
List.indexOf, but this doesn't seem like a good idea
You want to save the world name or uuid
Not int
Location is already serializable
smoky anchor
I would do UUID
World.getUID
(Why is this the name md, why)
sullen marlin
You can .get and .set it from a config
torn bough
Okay I think needed context
I'm making a home plugin, and when the player runs a command it saves their location
And if they go to a different world, they need to be able to /home back to their saved world
The UUID method would work well but I save all the player home data in PersistentData
undone axleBOT
You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs. Learn about more persistent data types here: https://www.spigotmc.org/threads/more-persistent-data-types-collections-maps-and-arrays-for-pdc.520677/
torn bough
I will try to UUID
smoky anchor
Idk which resource gave PDC for UUID only
wheat kiln
if (p.getInventory().contains(new ItemStack(Material.GRAVEL))) {
p.getInventory().removeItem(new ItemStack(Material.GRAVEL));
p.getInventory().addItem(new ItemStack(Material.FLINT));
}
This only allows it if its a stack of one item and if I add an amount it sets it to only that amount
how can I allow it to be an ItemStack of any amount
sullen marlin
Look at the other contains overrides and/or the docs for removeItem
torn bough
I would do UUID
`World.getUID`
(Why is this the name md, why)
This code doesn't exist
World world = [retrieve the world using the uuid]
smoky anchor
Bukkit.getWorld(UUID) does exist
smoky anchor
This code doesn't exist
And the docs say this exists as well
sullen marlin
They're probably on 1.8 or smthing
smoky anchor
not if they are using PDC
torn bough
I don't know why it wasn't popping up when typing getWorld. I had to specifically do Bukkit first but alright
sullen marlin
Do you know java?
smoky anchor
welll- ye
Are you new to Java ?
torn bough
I don't consider myself new?
I mostly do C# I don't know if that changes anything though
Anyway, testing right now
quaint mantle
.GetWord ahh
torn bough
How do you force getWorld to take in a UUID instead of a String?
A UUID is a String right?
quaint mantle
A UUID is a String right?
No
quaint mantle
How do you force ``getWorld`` to take in a UUID instead of a String?
UUID.fromString(yourstringuuid)

did you know c# code is offloaded to microsoft datacenters to be ran? the memory usage you see is for the Telemetry and Spyware
smoky anchor
How do things work when I am without internet connection tho 🤔
quaint mantle
Microsoft do some telemetry on .NET

I got my first plugin completed 😄
probably the wrong channel to say this tho
