Hey
Do anyone know
how to commit a ECLIPSE project in GITHUB without making it inside the folder of the project in github?
hahhaa
Its a Maven Project btw
stable roost
does anyone know if there is an issue with creepers not being scared of cats in spigot 1.16.1? i've built a farm that isn't producing 6x the amount as its vanilla counterpart. mob spawning in spigot, in general, is fine. the creepers are just not running to their doom and despawn instead. thoughts?
what do you mean that there should be an issue? are you saying, based on the screenshot (i don't understand the code), that the code alludes to there being a problem?
ok, so based on the pathfinding code, there isn't an issue?
neon epoch
I think so, I'm currently trying to cancel EntityItemPickupEvent on villagers, to prevent them from being willing to breed in the first place.
bold anchor
mobGriefing can be turned off.
neon epoch
trying to avoid it, because i still want mob griefing otherwise
timber thorn
So, another question regarding best practices:
wise flame
if the entity associated with picking up the item is a villager, set cancelled to true.
Do note that villagers that already picked up food will still breed.
timber thorn
If I want a user to enter a color/format code in the config and I am parsing that string, what should I do if somebody enters something other than colors?
Extract the color information from what the user entered? Discard the input and use a default?
wise flame
public void onEntityPickupItem(EntityPickupItemEvent event){
if(event.getEntity() instanceof Villager) event.setCancelled(true);
}
You can do
ChatColor.translateAlternateColorCodes('&', StringToTranslate);
You can do
ChatColor.translateAlternateColorCodes('&', StringToTranslate);
@neon epoch I know I can translate it, that's not what I am after.
bold anchor
Translate, strip check length
neon epoch
whats the difference between
getEntityType() == EntityType.VILLAGER
AND
event.getEntity() instanceof Villager
bold anchor
Not terrible much
timber thorn
So I want the user to enter a color that gets used frequently in messages and gui and stuff, basically a way to customize the gui.
Which means that string they entered will get copied often
So if they enter "&6", that should not be an issue to copy. If they enter "&6sometext&lblabla", that should not work. I know how to strip the color, I want to use a regex to detect if the input is valid. The question is what should I do if the input is invalid like above. Should I just shorten it to "&6&l", should I use a default, should I discard the input entirely and use no color at all? (of course I'd inform the user)
neon epoch
@rich quest go into your server files and delete the world's name, probably called "world", and it is in a folder in the main directory of your server
opal marsh
@frigid ember just out of curiosity, why is instanceof faster? Isn't the property check with an emum just an integer comparison?
neon epoch
How can i change villager breed willingness?
subtle blade
Entity#getType() and an instanceof check do two very different things
opal marsh
Right, that's why I was a bit confused lol
subtle blade
EntityType == vs Entity instanceof serve two separate purposes. While entity instanceof Zombie will encompass villager zombies and husks, entity.getType() == EntityType.ZOMBIE will not
instanceof ensures that a type is or is a subtype of the type on the receiving end of the instanceof
wise flame
@neon epoch You might be better off trying to cancel their breeding attempts
wraith thicket
Zombie is extended by Drowned, Husk, PigZombie, ZombieVillager.
So checking for instance if Zombie can be any of those.
However, EntityType.ZOMBIE is just the actual zombie
Well, covered by Choco already, RIP
opal marsh
...
public EntityType getType() {
return EntityType.CHICKEN;
}
}```
@frigid emberA quick search shows that there's no easy way to do it. You'd probably have to deal with NMS unless I missed something.
opal marsh
doesn't seem like there's anything much going on
pretty sure it really is just an int comparison
neon epoch
@wise flame i did that, successfully for that matter, but they are still willing to breed, and still giving off particles showing such
neon epoch
correct
wise flame
Whenever a villager tries to breed, try calling villager.setBreed(false);
neon epoch
but theyre constantly giving off particles because theyre willing to breed, but their EnterLoveModeEvent is being cancelled, so they just try again
ok
ill give it a shot
wise flame
should work
We don't see baby villagers trying to have children and they have that flag set
lol
be sure you want this though
you probably can't reverse this easily
stable roost
@frigid ember when i place a cat and creeper in that way, i get that behaviour too so no issue with that. however, when i build a creeper farm, that works as intended in vanilla, it doesn't in spigot. some creepers happen to wander off to their doom but most don't. it's as though they don't register the cats.
wise flame
@neon epoch above warning
neon epoch
wdym you cant reverse it easily
opal marsh
@neon epoch a shenanigan you could try is emptying the inventory of the villager because iirc they need a certain amount of food to breed
neon epoch
Ok, here's where I'm at, I want to clear the villager's inventory whenever they pick up anything, or try to breed, but I can only get their inventory if it is an AbstractVillager object, how do I take e.getEntity(), and change that to an AbstractVillager?
subtle blade
If it's of that type, you can cast it as such, schmiffy
AbstractVillager villager = (AbstractVillager) entity;
neon epoch
Eclipse is telling me that AbstractVillager cannot be resolved to a variable, I have it imported, and everything.
subtle blade
on what version?
Villagers were abstracted out like that in like 1.13. Whenever the wandering trader was introduced
grim halo
Why would you want to downcast?
neon epoch
?
grim halo
Villager extends AbstractVillager
neon epoch
Oh, because I cannot access its inventory unless it is abstractvillager
grim halo
So if you check if its of type Village you should just cast to Villager
Wait that doesnt make sense. Villager extends AbstractVillager that means it inherits every method
frigid ember
i was trying to make a spigot server but it says there is another program trying to open the files at the same time
neon epoch
So do i need to make a villager object that is the event entity casted to villager, then go from there?
grim halo
@frigid ember Whats the exact message?
@neon epoch Yes i would try just using the Villager interface. Although i find your bug weird.
frigid ember

lofty meadow
Hello!

What do `var3`, `var4` and `var5` for? Which delay, which ...?Ok, thanks!
grim halo
@frigid ember Weird. Did you try to start the server before? Try restarting your pc
lofty meadow
But why did you respond extremely fast like you know I will ask about it? 😄
grim halo
@neon epoch You can cast Entity to Villager if you have checked it before
neon epoch
grim halo
That is not a valid java statement
neon epoch
whats wrong about it?
if you want me to assign that value to a villager object, i can, the error will still be the same
grim halo
You need to define a new variable that stores the casted object
Why cant you just access the inventory with Villager#getInventory
neon epoch
Im not sure why, but eclipse isnt importing villager.
thats why these issues are happening
grim halo
Does Villager override the getInventory method?
wraith thicket
He suggested that because that's what was asked for ...
wise flame
So. I'm working on figuring out how to delete a world without multiverse.
I know that I need to unload the world and make sure to remove my references to it so garbage collection eats it, then delete the world file, then make a WorldCreator to make a fresh overworld
What happens to players in the world?
How do I make sure players will spawn in a newly created overworld by default?
grim halo
@neon epoch define a new variable and post the eclipse warning pls
neon epoch
I had things double imported, and i had imported both abstractvillager and villager, for whatever reason its fixed
grim halo
@wise flame If you unload a world then it would make sense that every player in this world gets thrown to the server spawn. If not they get probably just kicked
@neon epoch Let your IDE handle the imports. I have not imported packets by hand for ages (last time when i worked with OpenGL srtatic wrapper)
frigid ember
How would I get the location to the right of a player
neon epoch
ok thanks
grim halo
You first have to define "right".
So you can get the direction the player is looking at -> convert to BlockFace -> get next 90° BlockFace (rightFace)
-> get Block of players feet -> Block#getRelative(rightFace)
frigid ember
Ok ty
timber pike
Is it bad practice to use commandblocks to store literal strings?
I don't see any drawbacks but im not sure
neat orbit
is anybody experienced with votingplugin and know how to do cummulative rewards ?
u don't have to be experienced lol just do u know how to do cummulative rewards
neon epoch
I have no idea why this isn't working, to preface, I'm trying to prevent my players from breeding villagers. When I cancel EntityEnterLoveModeEvent, villagers should stop looking at each other, and giving off heart particles, correct?
neat orbit
mrschmiffy idk about that but have you tried setting the chunk limit of villagers?
or maybe try disabling the baby villager mob
neon epoch
or i just kill the baby villager as soon as its spawned. ill give it a shot, thanks.
neat orbit
sounds time consuming to me
grim halo
@timber pike What do you mean by that... If you program a plugin you should never have to save Strings in command blocks. That would be a very bad practice.
silent pulsar
Hello, quick question, is it possible to have a method executed rather than a command that executes our method, because it's really not clean to do like that. If this is not possible, is it possible to add this feature to the bungee api? (I can make an issue on github if needed)
timber pike
oh
ok lol
What do you recommend I do?
I'd rather not read from a local file unless that's my only option
grim halo
@silent pulsar Pls elaborate. A command is literally a method.
silent pulsar
Yes, but we have to register it in the .yml plugin.
grim halo
@timber pike What do you want to achieve?
silent pulsar
and create an class witch implement CommandExecutor
it's not clean to do that :/
timber pike
Im storing item meta in a command block then giving the item to the player based on what it is in the command block so a command block might contain
crossbow true true false BINDING_CURSE 1
silent pulsar
it's not clean to do that :/
grim halo
@silent pulsar There are a lot of frameworks that let you register commands wihtout the plugin.yml
I for example use aikars ACF (Annotation Command Framework) its a bit hard because you need to have more
java experience but that would be a "clean" way. (Although i dont understand why the default method is not "clean")
@timber pike And you want to do that per chunk or why do you need to store it in a command block?
timber pike
well its just easily editable in game, and its easy to link up with a button since right now the command block is just ~ ~-10 ~ away
i just dont know if its bad to do
grim halo
I have never ever seen anyone do that and you should def avoid command blocks on a production server...
grim halo
You can however use signs or a book if you want to edit stuff ingame... Also the normal way would be writing commands to interact with your plugin
neon epoch
I've seen anvils too, then you just get the itemmeta of the object, and get the name
grim halo
You cant store data in anvils
neon epoch
Oh I was thinking of a temporary way to have the user enter a string not through a command, sorry
timber pike
signs would work i guess
grim halo
Oh yes. Thats possible. But a bit complicated
timber pike
im just implementing a kit sort of system im not sure how to link one button to another command
but if i know that the sign is going to be ten blocks below the button or one block above its easy to link them together
grim halo
You coudl just use the PlayerInteractEvent and check if he clicked a button. This way you can add functionality to every button you like
timber pike
yeah i am
but how do i know what button goes to what
does that make sense?
all i know is that its a stone button
grim halo
Or even better you just place a chest below the button and then copy the chest content into the player inventory
grim halo
:p
timber pike
also while you're here
is there a reason the spigot community uses yml instead of json?
or is that a java thing
grim halo
Spigot has a build in FileConfiguration api that uses yml
I for my part only use json and the provided Gson from google that is also build in
timber pike
👍
grim halo
If you only use this for your private server its fine
timber pike
any reason why it wouldn't be for production?
though yeah this is only going on a private server
grim halo
So you place a sign on top of your chest with a secret code on it.
This way you can just click a button and check 4 blocks below for a sign and check the code
If it is right you go on block lower and get the chest content.
This way you prevent random ppl from placing a chest 5 blocks below to just copy every content
timber pike
mk
grim halo
But that is still NOT safe. Someone with a wallhack can just read the sign
timber pike
yeah its fine the risk is tolerable to the project
grim halo
Ok
timber pike
thanks a lot lol
grim halo
np
subtle blade
Shouldn't cater to hacked clients
They're cheating. That's not something you can predict
If they can cheat in the vanilla game, expect them to cheat your plugins too
grim halo
Ah you can use §e§a§e§a§e CODE etc as the color codes are all hidden i think.
The player would only see the yellow CODE and would not be able to reproduce the full String
grim halo
I mean the proper way would setting a persistentDataTag on the chest anyway but if he wants a quick simple solution this is fine
ish
neon matrix
He is just making a button that give the items in a chest?
hollow thorn
But that is still NOT safe. Someone with a wallhack can just read the sign
@grim halo cant you just lock the chest

Here's a (potentially dumb) question, what does PAIL actually stand for when renaming fields/methods? 😄
subtle blade
This is what vanilla does

so first it summons it, then it sets block to air?

btw is It normal that if i get a block location, and spawn a primed TNT at that block location, the Primed tnt will actually not spawn there?
timber pike
i dont see an onEnable method?
also the class should be called Settings not settings

depends on where you're spawning it, Viper
timber pike
class names always start with an uppercase
subtle blade
keep in mind that a block's position is 0, 0, 0 relative to that block. The bottom left most corner
sturdy oar
it is kinda offset
violet aspen
oh ok sry im a Beginner

Everything works except for the event
subtle blade
I'd blame that likely on the condition instead. That event should be called and it likely is, though that condition is most likely false
oh, wait, yeah it is lol
player.getInventory().getName().equalsIgnoreCase("Settings")
player.getInventory() is the player's inventory, not the one it has open
timber pike
^^^ check that its not with the event code
frigid ember
how do i make it so if i click an item it runs a command
timber pike
also if it still doesn't work then it might be CommandExecuter and EventListener conflicting for some reason
violet aspen
ok
timber pike
you can just test whether its firing by putting a line of code that says in chat like "I work" or smth
timber pike
oh yeah lol
subtle blade
You want to check the clicked inventory's name. event.getClickedInventory() (which can be null if clicking outside of it)
timber pike
Also, does creating a new thread cause commands to run twice?
subtle blade
that's a very vague question lol

if I create a synchronized runnable to do a countdown does that cause a command like /give to execute twice?

Turn the delay value into a variable and then print it to check its right

@soft grove You want to
a) store your list of commands outside the scope of the scheduled task
b) run one command within each
In order to do so you'd need to keep track of your position in the list and reset it to 0 when you reach its end (or you could probably use some pre existing collection that does the roll for you)

there is something wrong with the value ig cuz it returns zero

is it possible to detect wether a chunk was unloaded clientside by a player meaning if a player unloaded a chunk on his screen but another one is still in it
grim halo
You can detect the chunk packets that get sent to a player. There is one that sends the chunk and one that "unloads" it for the player.
You cant actually check what player triggered a chunk unload as the chunk only gets unloaded if the server feels like it.
But you can keep track of what player sees which chunk.

Hi, I am trying to create custom items by creating a class that extends ItemStack. When I add that item to an inventory and get it again using PlayerInventory#getItemInMainHand, any instanceof checks to see if it is the class returns false. Is there any way I can fix that?

Three questions. 1) what event is the best to turn on/off game rules (like fire tick, fall damage, etc)? 2) How would I be able to stop player's from burning in lava (I thought fire damage would do it, but it doesn't? 3) I want to check if a player is standing on a beacon and only a beacon, and if they are do something. What would be the best event for that?

That's general hex notation.

What about the game rule's not damage related (i.e. ANNOUNCE_ADVANCEMENTS, DO_DAYLIGHT_CYCLE, etc.)?

What do you mean event?

Game rules?
lone fog
I don't think there is an event for when they are toggled, but you can use PlayerCommandPreprocessEvent to listen for them I guess
unkempt ridge
yes sorry typed that too fast @subtle blade
subtle blade
No event necessary. See World#setGameRuleValue() (or setGameRule(), can't quite remember)
lone fog
But that doesn't tell you when they are changed
Unless you use a repeating task to check them

Oh is that what he wants?

I just want to turn like daylight cycle, weather, advancements, all off

Yeah you can do that with World#setGameRuleValue()

Should I do that in onEnable()? When I looked quickly on JavaDocs I found WorldEvent

Sure. You could definitely do it onEnable() if you'd like

((CraftEntity) vehicle).getHandle().setInvisible(true);
ent.setPassenger(vehicle);
vehicle.setPassenger(pl);
}
}```the mob
yes.
but thats not possible without protocollib
at least thats what people said
so they told me that I should try this
now its 'ent.setPassenger(vehicle)'
but it should stay there(stick there) and the mob should follow the location of the boat
lone fog
You will 100% need protocollib or nms to make it look half decent
Best you can do without it is teleporting the mob to an invisible horse the player is riding
frigid ember
but that'll have a difference in height with most things I believe
lone fog
That's why I recommend making NMS extensions of each entity and modifying them to be controllable
frigid ember
NMS would be only one version right?
lone fog
You can make it multi version with a bit extra work

smartest thing would be to make it which the latest version than right?

and then maybe when they switch off of it u clear it?

it was PlayerItemHeldEvent
although if they pick up the sword without swapping items, or get it from a chest then it wont trigger

your initilaiizing the Drugs class, so you need to be using parentheses
not brackets

there's no difference

the bottom one is what I'm familiar with so probably
high mantle
like I said i rarely use arrays aside from varargs and even then I usually convert them to Lists
its just so much easier to work with
cinder kindle
how would you go about this with a list

Dudes, I'm new to Java programming, I have a fast question... I'm using IntelliJ, when I build my project, it's a 32mb jar
and it's just a print test lmao
grim halo
You are shading the whole spigot server in then...

okay got a question... 1.8 help isnt supportet i know... i am creating a scoreboard with bungeecord. If i use it on 1.16, on create it shows this error:
On 1.8 it works perfectly. so how should i format my scoreboard? idk anything about json tbh
high mantle
whoops
spark phoenix
Isn't compile supposed to just use it for compile purposes?
grim halo
Do you use the mcdev plugin or maven?
grim halo
high mantle
if im correct you're not creating any new instances of the class, you're just making an amount of indexes
maybe that's it?
if not then i seriously don't know. there are lot smarter people than me
i just came on to ask a question lol
spark phoenix
Where can I see that dependency file? Can't see it
grim halo
Its your pom.xml
And with maven you dont use jar files from your system and you dont export the project by hand

I am attempting to generate a world the moment a player places a metadata sign, then paste a schematic inside it using the ConsoleCommandSender and WorldEdit to create the lobby. It is an empty world, the class used for chunkdata is as follows.
public class VoidWorld extends ChunkGenerator {
@Override
public ChunkData generateChunkData(World world, Random random, int chunkX, int chunkZ, BiomeGrid biome) {
return createChunkData(world);
}
}
This generates like normal, but whenever the consolecommandsender attempts to load and paste the schematic at the specified coordinates, it comes up with the error "the world was unloaded and the reference was unavailable" (error log at the bottom of message) that points towards these lines:
Bukkit.dispatchCommand(console, "/schematic load bedwarslobby");
Bukkit.dispatchCommand(console, "/world bedwars" + i);
Bukkit.dispatchCommand(console, "/pos1 " + spawnCoords);
Bukkit.dispatchCommand(console, "/pos2 " + spawnCoords);
Bukkit.dispatchCommand(console, "/paste");
all variables used for the dispatch command are here:
World world = Bukkit.createWorld(new WorldCreator("bedwars" + i).generator(new VoidWorld()));
Location spawn = world.getSpawnLocation();
String spawnCoords = spawn.getBlockX() + "," + spawn.getBlockY() + "," + spawn.getBlockZ();
ConsoleCommandSender console = Bukkit.getServer().getConsoleSender();
I assumed the world was loaded upon creation, but I guess not. How would I get this to occur?

holy
high mantle
this is a repost because no one answered it a couple nights ago
spark phoenix
Ok I'll take a look, thanks 7smile7
tough kraken
a massive block of a message...
high mantle
its only because its a bunch of references
tough kraken
ah
high mantle
so i looked into it myself, and it works fine until i unload and delete a world
im pretty sure its the unloading that causes the issue
tough kraken
man 1.16 is so weird sometimes
high mantle
ye
grim halo
createWorld creates/loads the world
spark phoenix
Now that I'm thinking, nevermind I' not using Maven, I just used it to generate a offline javadoc
I manually imported the API
(I don't have a pom.xml)
grim halo
Ok then you build an artifact right?
spark phoenix
yes
grim halo
np
high mantle
well thats weird then. WorldEdit doesn't seem to think so even though I just made it
if I were to unload then delete a world, then soon after create a new world with the same name, would that cause worldedit to trip up?
maybe it looks at it via name, and when i unload the world it remembers that unloaded world name
regardless of if its actually a new world or not
grim halo
Referencing a world by its name and then re creating it completely on runtime just begs for problems.
Also why dont you use the worldedit api?
high mantle
because all i can find is their project managers and i don't use that
lilac gorge
does anyone know a flag or plugin that disables certain armor types, and items with enchants inside a world guard region?
grim halo
What do you mean by project managers...
high mantle
maven, gradle, etc
high mantle
its also easier just to make the console run the command
grim halo
Might not work with WE
Yes but then you run into problems like that. With the api you could reference worlds by their uuids
high mantle
true
grim halo
Your problem could be the cache that is used for something like /undo yields a world reference or name -> world link
No idea... just increment i every time a world gets created
I have no idea why you would want to create/delete so many worlds at runtime anyways...
high mantle
the idea is to have a world per lobby, since the game mechanics can get a bit intensive
grim halo
A world per lobby of a minigame?
high mantle
the game lobby
grim halo
"the game" lobby?
high mantle
ok
so there are hub lobbies in other servers - the one im in doesn't have that since we're not big enough for it to matter, but it does matter when it comes to fps/performance, so its important that all game sessions are in their own world
for there are multiple signs, each one intrinsically linked to their specified world, and when right click it sends the player their to the game lobby, where they wait until they have enough players to start
therefore i need to create a way that's easy enough for them to create these lobbies and allow players relatively easy passage to these lobbies.
when the sign is broken that world is unloaded to prevent a session lock error happening, then the world folder is deleted
grim halo
Then your plugin is for personal use only?
high mantle
it is private yes
grim halo
Then just create 3 worlds per game at the start and link the signs to them.
tiny dagger
but how badly can a world be damaged?
🤔
I recommend only storing the damaged blocks in a deque
grim halo
I mean it is possible to create worlds when the sign is placed and remove the worlds when the sign is destroyed but if you need to use to dispatch commands to use worldedit you should not try to tinker with worlds like that.
tiny dagger
not sure but wasn't world unloading making leaks?
i'm sure for example i store location
a plugin unloading that map
grim halo
Depends. If you are carefull then not.
tiny dagger
could still be kept by a plugin
just for having that location reference
tho
locations are weakreferences now
grim halo
Does a location hold a strong reference to a World? let me check.
tiny dagger
it does not
but that doesn't mean other plugins don't use worlds
in different ways
high mantle
thats how i link my signs to their worlds
