Yes. But as a general rule you should not keep loose Datastructures in your JavaPlugin class.
Create an actual class, put your Map in there, and dont let other classes access the Map directly.
Rather write new methods like
public String getCapitalCityOfCountry(String countryName) {
this.capitalMap.get(countryName);
}
Which is much more expressive.
timid berry
if i do something like
capitalCities.put("Germany", "Berlin");
but germany already has a value, will it overwrite or error?

Yes. But as a general rule you should not keep loose Datastructures in your Java...

It will overwrite it. You can hover over the Map object and read the JavaDocs. They should state the contract of the Objects Methods.

so why there is not getMap() but there are sections

getValues()

i feel like im repeating questions but

You should be using the sections
pure dagger
sorry
wet breach
Just listen to Olivo, they know their stuff ๐
chrome beacon
Not the maps that are used in the internals
brittle geyser
@NotNull Map<String, Object> getValues(boolean var1);
there is no 'List'
Probably you can get List<Map<String, Object>> but it is stupid
chrome beacon
getMapList does exist if you want to get that
Anyways you can think of a config section as a wrapper for the map to make it easier to properly access the values
Internally it is backed by a map
A LinkedHashMap I believe
echo basalt
why does getMapList return a List<Map<?, ?>> instead of just a List<ConfigurationSection>
in what scenario would the key not be a string
pure dagger
now here, whats enchantments, a section? like "enchantments" (string) is a key and there is section as value? am i right?

yeeesss

in what scenario would the key not be a string
keys can be any scalar type

eternal oxide
then don't
sly topaz
why would they change
eternal oxide
generate your key based upon unique identities

as long as your hashCode is implemented properly, reconstructing the same object will deliver the same hash code
inner mulch

eternal oxide
its your object, you have full control
sly topaz
but i cant expect other people to do so
is this some kind of API
inner mulch
yes
sly topaz
well, ultimately you do expect anyone who is using a hashmap to obey the rule of thumb
the default hash-code being dependent on the memory address makes it all the more annoying, unsure how you could avoid people using it that way
you cannot possibly expect the default hash code to be the same after being reconstructed
inner mulch
yeah
sly topaz
just document it in your method
that your map expects a valid equals & hash code impl
nowadays that isn't hard with records being a thing
lilac dagger
which form do you guys prefer:
sly topaz
ultimately, you could force the user to use your key wrapper so that you can control the hash code impl @inner mulch

You're running 1.21.1? 
sly topaz
worldly ingot
Are you Wicklow? Is this your plugin?
earnest girder
yes
worldly ingot
Okay, so your UseGun#updateLore() method method is trying to set an integer on a byte value in the PDC
earnest girder
yeah but im not, let me show you code one sec
worldly ingot
Yeah only that method should be relevant I think
Or I guess anywhere else you get/set the relevant NBT field
earnest girder
worldly ingot
Which #get call is line 283? id, ammo, or mode?
And is this on a freshly generated item? Because if this is happening on an item you just created now, the only way that would happen is if you set one of those integer fields as a byte somewhere
earnest girder
Which #get call is line 283? id, ammo, or mode?
id
int id = container.get(keyID, PersistentDataType.INTEGER);
Yeah, then I guess just look for instances of set() for the id key and see if any are set to bytes. Not really sure why else it would be yelling at you. The NBT clearly has it set as a byte value
If you look at the custom data component it likely will have it set as 0b (or whatever the value is, suffixed with a b)
Or maybe you had it set to a byte before and you're still using an item from when it was a byte
earnest girder
well it says that its looking for a byte and cant store integer, right?
it should be looking for an integer, I dont use bytes anywhere
earnest girder
If you look at the custom data component it likely will have it set as `0b` (or ...
yeah I have seen that in my logs
in the item's meta
inner mulch
how do i get a non null mapview? getmapview returns null even tho create the item beforehand
worldly ingot
well it says that its looking for a byte and cant store integer, right?
Nah it says it's trying to store an integer but there's a byte at that field
The message is a bit misleading because it's a get() call. The error should probably just be "Expected Integer but found tag instance NBTTagByte"
And while yes, in theory, you should be able to upcast a byte into an integer, NBT is a bit strict on its typing system
earnest girder
worldly ingot
Mode being a byte makes sense because it's a boolean and NBT represents booleans as 0 or 1 as a byte, so that's fine
worldly ingot
Yeah so it's set as a byte somewhere, especially because ammo is set correctly as an integer
earnest girder
ok
worldly ingot
So you know at least CraftBukkit isn't at fault here because it's serializing ammo as expected, even when the value is 1
Must have accidentally copy/pasted a PersistentDataType.BOOLEAN or PersistentDataType.BYTE in one of your set() calls
A copy/pasted boolean type seems plausible though :p

Odd. Make sure Spigot is up to date and if it is send your code
Is this where I check if its up to date? I dont have any newer versions shown in hints.
<groupId>org.spigotmc</groupId>
<artifactId>spigot-api</artifactId>
<version>1.21-R0.1-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
Here is my function
public void scanAreaForTargets(Mob mob) {
if (getEntityTeam(mob) == null) return;
double radius = 16;
List<Entity> nearbyEntities = mob.getNearbyEntities(radius, radius, radius);
LivingEntity closestTarget = null;
double closestDistance = Double.MAX_VALUE;
for (Entity nearby : nearbyEntities) {
if (nearby.isInvulnerable()) continue;
if (!(nearby instanceof LivingEntity livingNearby)) continue;
Bukkit.broadcastMessage(inSameTeam(mob, livingNearby) + "");
if (inSameTeam(mob, livingNearby)) continue;
double distance = mob.getLocation().distance(livingNearby.getLocation());
if (distance < closestDistance) {
closestDistance = distance;
closestTarget = livingNearby;
}
}
if (closestTarget != null) {
mob.setTarget(closestTarget);
}
}
That one broadcast message returns false which means it passes all the checks. As I said, it works fine for all mobs except for breeze

How to make a function that gets a block and 4 booleans to which sides it should connect. The function is only applicable to iron bars and should connect them to the specified sides?
slender elbow
Here's a function that takes a block and four booleans (one for each side) and connects the block accordingly if it's an iron bar. This uses the Spigot API and requires checking and updating the block data properly.
In Minecraft, iron bars use the BlockData interface and specifically the MultipleFacing interface, which allows setting connections to specific sides.
Here's how you can implement the function:
import org.bukkit.block.Block;
import org.bukkit.Material;
import org.bukkit.block.data.BlockData;
import org.bukkit.block.data.MultipleFacing;
public void setIronBarConnections(Block block, boolean north, boolean east, boolean south, boolean west) {
// Check if the block is an iron bar
if (block.getType() != Material.IRON_BARS) {
return; // Only apply to iron bars
}
// Get the BlockData and cast it to MultipleFacing for connecting sides
BlockData data = block.getBlockData();
if (data instanceof MultipleFacing) {
MultipleFacing ironBarData = (MultipleFacing) data;
// Set connections to the specified sides
ironBarData.setFace(BlockFace.NORTH, north);
ironBarData.setFace(BlockFace.EAST, east);
ironBarData.setFace(BlockFace.SOUTH, south);
ironBarData.setFace(BlockFace.WEST, west);
// Update the block's data
block.setBlockData(ironBarData);
}
}
Explanation
- Check Block Type: We check if the block is of type
IRON_BARS. If not, we exit the function early. - Get Block Data: We retrieve the block's
BlockDataand cast it toMultipleFacing, which allows us to set faces. - Set Connections: Using
setFace(), we set each specified side totrueorfalsebased on the given booleans. - Update Block Data: Finally, we update the block with the modified
BlockData.
Usage
To use this function, simply pass the block and four booleans specifying which sides to connect:
setIronBarConnections(block, true, false, true, false);
This example would connect the iron bar to the north and south sides only.

vernal oasis
Because people suggested it
wet breach
probably for all the wrong reasons

vernal oasis

wet breach
99% of projects in regards to plugins will never be large enough to see any speed improvements. Don't require some unique build setup. Or have some other special requirement that would make gradle a necessesity
vernal oasis
Ye but it seems easier?
wet breach
in what way?
slender elbow
gradle is perfectly just as valid to use as maven
wet breach
obviously its not if you are asking for tutorials and you already know maven
in what way is that easier?
vernal oasis
It looks simpler and such
vernal oasis
obviously its not if you are asking for tutorials and you already know maven
Know is a strong word
wet breach
gradle is perfectly just as valid to use as maven
Indeed it is, just kind of countering the common troupes tossed around in regards to gradle
its not bad obviously if used right
and there is some things maven has that some people hail gradle for ironically too
vernal oasis
I'm in a beer tasting class rn so I'm getting wasted for college credit ๐
I know for a fact my maven setup was not correct
wet breach
how was it not correct?

so you have no clue how to compile but want to make plugins o.O
devs are weird these days, don't even know the tools they use -.-
vernal oasis
Nah I've made plugins and such before, I just updated from a previous version so things are janky
Stuff changed in 1.21 that I've not kept up with really so stuff kinda broke
wet breach
https://paste.md-5.net/duzecayecu.xml
and what error do you get when compiling?
vernal oasis
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.13.0:compile (default-compile) on project CUU: Fatal error compiling: java.lang.NoSuchFieldError: Class com.sun.tools.javac.tree.JCTree$JCImport does not have member field 'com.sun.tools.javac.tree.JCTree qualid'
you're using 1.18.28
wet breach
clearly that line says otherwise
vernal oasis
Oh what
I shall try this later when I'm back from classes. Thank you. I will update you
wet breach
now do a clean cycle and then build
vernal oasis
(slightly drunk)
wet breach
someone is a light weight
wet breach
anyways, doing a clean first helps ensure the cache gets cleared and doesn't interfere with your build you are trying to get to complete
once compiling works perfectly don't use the clean cycle ๐
vernal oasis
Yuh
wet breach
also your maven shade plugin is outdated and using scope system is generally not acceptable anymore
vernal oasis
Is there any reason to make a shaded?
wet breach
shaded means to take the classes from another project or jar and to put it into your project jar
if you are not using maven shade for that, then I guess you can remove it since its not being used lol
vernal oasis
Just remove the <goal>?
wet breach
o.O
remove the whole plugin section for maven shade
if you are not making use of shading
vernal oasis
wet breach
So https://paste.md-5.net/duzecayecu.xml#L21 - 44?
31-43
if you start at 21 you will remove the compiler plugin
and thus no compiling will happen ๐

hey i discorer that can someone explain me further cause i try with some thing like localhost and all work, but i try on a bungee server and it don't work any idea why?
wet breach
which is kind of the opposite of your goal currently
vernal oasis
if you start at 21 you will remove the compiler plugin
Oop yup

localhost would be localhost of the player
vernal oasis
That ye
tidal kettle
You need to give it the correct ip
yep itry
vernal oasis
which is kind of the opposite of your goal currently
Ty
tidal kettle
but sometime it doesn't work
wet breach
localhost would be localhost of the player
this is not correct
localhost would refer to the host the application is currently running on
however typically it refers to 127.0.0.1
which wouldn't work for transfer
since its not a public ip
but it depends on the OS as some OS's default localhost to the local ip assigned via router
while the majority assign it the loopback address
eternal night
no, olivo was right there.
vernal oasis

that string is not evaluated until it reaches the client
.transfer on spigot does absolutely nothing but send a single packet
no name resolution etc
all that is left to the client
wet breach
that string is not evaluated until it reaches the client
oh right, @chrome beacon sorry you are correct but the additional stuff I said still applies ๐
eternal night
dat true 
chrome beacon
Should work just fine
tidal kettle
imma try on a local bungee and tell you after
edit: all work i'm just dumb
chrome beacon
but why are you using it instead of the Bungeecord
If you're on a Bungeecord you should tell the Bungeecord to change server
instead of the client
You most likely want the pmc instead
?pmc
tidal kettle
i know but i justwant to know more about the .transfer x)
