where is this class
if it's not in the jar you download, then is it in your plugin jar?

no its not anywhere i realise now and i have been stupid. i forgot it was only there when i shaded
wraith rapids
shade it in
wraith rapids
look at the pom or build file of the dependency you're downloading
it will have the version information

it works now thanks
wraith rapids
or you can see it in your ide as well, look at your maven dependency tree

You should probably read on some basic java concepts but essentially the return type of Arrow::getNearbyEntities is Collection<Entity>
so in order to store it into a variable you would have to do something like:
Collection<Entity> entities = arrow.getNearbyEntities(0,0,0);
wraith rapids
it won't magically turn your Collection<Player> into a Player
it will explode
it looks like it works without exploding in your ide because you're telling your ide to trust you on it

Does anybody know the best way to create runnables per entity?
Im currently using hashmaps, but this doesnt seem to work at all in my case
i have a plugin where when you run a command a chicken starts coming towards you and when he is close enough he gets removed
The close enough checking works with a runnable
but the runnable gets very fcked when there is more than 1 chicken
Ill provide the code
ivory sleet
Sure do
dusk flicker
?paste
queen dragonBOT

here im detecting the close checking (if the chicken is close enough to be deleted):
https://paste.md-5.net/mazisakoqa.java

for (Entity tempEntity : entities) {
tempEntity.addPotionEffect
}
}
}
}
}
}```you forgot the register the event
vital ridge
Sure do
the problem is that the detector starts messing up when its more than 1 chicken, for example it only deletes one of them and the other chicken's runnable just keeps running
Like im not sure if im using the hashmaps wrong
or is it something else
I always mess up with those per entity runnables

Those are just tags. There is a Tag class with constants containing all the tags in the base vanilla game
ivory sleet
canyou recommend a tutorial too :)
If you don't know java I would suggest learning fundamentals in that before tackling Spigot API.
worldly ingot
In that case, Tag.FENCES and Tag.WOODEN_FENCES
You can't get the Tag to which a block belongs though, unless you write a method to iterate over all the tags and find which ones contains a Material
Which should be easy enough given that there's a Bukkit#getTags() which returns an Iterable<Tag<?>>
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Server.html#getTags(java.lang.String,java.lang.Class)

i want an error message of your target isnt online or couldnt be found if a player just does /freeze without a player name or /freeze player name that doesnt exist, but i can only get one error message to work at a time
proper notch
You check if (args.length == 0) after you request Player target = Bukkit.getPlayerExact(args[0]);
Therefore, if there is no player name specified you'll fire an IndexOutOfBounds exception as you're trying to access the index when it doesnt exist.
You should check if (args.length == 0), then you can use args[0]
worldly ingot
Shoulda been EnumSet 😒
I think it actually might be for the simple registries
Oh, nah. HashMap because it holds the NamespacedKeys as reference https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/Registry.java#185

You should check `if (args.length == 0)`, then you can use `args[0]`

Relevant commit
Goal of that libraries entry is to solve that very issue. And in the case where developers are trying to load .jar addons, they should be using their own class loaders instead of the plugin class loaders
But as far as libraries are concerned... if it's on central, the server can download it for you automatically and load it at runtime

vestal dome

worldly ingot
Run mvn clean install for Packets
worldly ingot
;p
vestal dome
skip that question
worldly ingot
I'm also curious. What would you define as normal?
paper viper
like mvn install?
cause adding clean just regens the binaries
with the new source code
worldly ingot
package only compiles a binary, it doesn't install it to your Maven repository
paper viper
that cleans binaries and compiles into jar (from new sources)
worldly ingot
Your computer has a local Maven repository which caches all the dependencies you've ever used while writing a Maven project
Additionally, you can install your own artifacts there
vestal dome
yup works....
worldly ingot
Maven's install goal does that so you can use it in other projects 🙂
vestal dome
Additionally, you can install your own artifacts there
yes I know... thank you for notifying me about it..

builder.append(String.format("\n \n➤ %s", page));
bookMeta.addPage(String.valueOf(builder));
Yeah, you don't want to String.valueOf() those
bookMeta.spigot().addPage(page)
You'll have to also append your \n\n>%s thing to the start of your component
You either use components or you use strings, you can't use both
BaseComponent[] page = new ComponentBuilder("\n \n➤").event(new ClickEvent(ClickEvent.Action.RUN_COMMAND, "/bc hi")).create();
bookMeta.spigot().addPage(page);```I don't think 1.8.8 has bookMeta.spigot().addPage(page)

Can't find much on it with google, would rather see if someone has anything before I go and make it myself

In my player object I store IP addresses as String to access quickly, id rather store it in that as the actual ip and in the database as the hash'd version
I haven't done much with hashing before so any pointers are appreciated lol

Best you could do is check if the hash is in the DB and if it is set the player object IP to the ip

it's just a transform, an __encoding__ of the bytes
that's like the one difference in the definition of the two (encoding vs hashing)
hashing is one way only
vagrant stratus
bas64 is indeed a hash algorithm
Base64
In programming, Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating the data into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding. Each non-final Base64 digit represents exactly 6 bits of data.
quaint mantle

quaint mantle
there is such things as two way hashes
such as?
wet breach
base64 is one of them

encoding isn't really a function
vagrant stratus
Base64 is an encoding and decoding technique used to convert binary data to an American Standard for Information Interchange (ASCII) text format, and vice versa.
quaint mantle
encoding isn't really a function
encoding is a process.. it's a function
you put data in, you get data out, and it's reversible
wet breach
therefore still a hash mechanism
quaint mantle
hashing is (ideally) not reversible
wet breach
the other hash mecanisms you are talking about, are not reversible and thus preserve the integrity of the data
quaint mantle
okay okay
link me to sources saying that base64 is a hash algorithm
This seems to explain it pretty well https://crypto.stackexchange.com/a/29240

hashing isn't for the purpose to secure data, rather ensure the data in question hasn't changed

```java

@vagrant stratus
quaint mantle
hashing isn't for the purpose to secure data, rather ensure the data in question...
base64 is a mechanism to encode bytes into another range of bytes, which does not serve any of those at all
wet breach
A hash function is any function that can be used to map data of arbitrary size to fixed-size values.
base64 fits that
it just depends how you are using base64 in whether it is encoding or hashing.
quaint mantle
base64 has no business in being used for verifying the integrity of the data
wet breach
The definition of hashing doesn't say anything about verifying the integrity of the data, just that is the problem most hashes set out to resolve
However there is other reasons to use Hash mechanisms though and doesn't have to be for data integrity
quaint mantle
hashing isn't for the purpose to secure data, rather ensure the data in question hasn't changed
hashing doesn't say anything about verifying the integrity of the data
👏
wet breach
don't need to
waxen plinth
Hashing is generally implemented very differently depending on what it will be used for
It is very important for security and it secures data by effectively allowing you to destroy it while retaining a way to check if a new piece of data matched the original
But to treat that type of hashing as if it's the same as what's used for hash tables is a stretch
In essence they do the same thing but they achieve it in extremely different ways because in one case you don't care much about collisions and in the other collisions are fatal
paper viper
Yeah one thing I recall in crypto is salt hashes
quaint mantle
and call it a hash function
waxen plinth
You can call anything a hash function
It doesn't even have to transform the data in any way
wet breach
UTF-8 is a character standard
waxen plinth
Hashing an int returns the same int in java
quaint mantle
UTF-8 is a character standard
it's an encoding
waxen plinth
The effectiveness of a hashing function like that is up for debate
quaint mantle
it encodes data which you can later interpret however you like, just like base64
therefore utf-8 can be used for hashing
wet breach
UTF-8 doesn't encode data
waxen plinth
If you're using it for security you want to ensure the original data cannot be derived from the hash and collisions are extremely rare
paper viper
Salt hashes
waxen plinth
lmao
wet breach
UTF-8 is a standard for defining the range of characters and their character points
wet breach
it in of itself does not encode anything
paper viper
I can’t understand that statement lol
waxen plinth
sha-256 is just a standard it doesn't do anything to data itself only defines what should be done to it
wet breach
alright not going to argue you semantics here
waxen plinth
Tell me
If I have a "standard"
In which each number represents a character
Like 1=a, 2=b, etc
waxen plinth
And you can take 1 2 3 4 and it is encoded into a b c d
Then it is an encoding
A caesar cipher is an encoding
utf-8 is just a glorified cipher so weak that everybody knows the key
It's an encoding and to say it's not an encoding is just willful ignorance
waxen plinth
Literally all of these say "encoding" within the first sentence describing what utf-8 is
waxen plinth
Not for security
"encode" doesn't even necessarily have any security implications
Encrypt does
But encode just means to translate basically
Using virtually any method
Transform the data in any way and you have an encoding of some sort
wet breach
both of you really should go to school for crypto then you would understand what is and isn't a hash function
quaint mantle
"UTF-8 doesn't encode data"

wet breach
There is one way hashes, and two way hashes also known as public algorithms
waxen plinth
People don't usually call java hashCode implementations hash algorithms
They call them hash functions
wet breach
typically one way hashes are combined with security because of their nature being one way
waxen plinth
The only thing that is really important to qualify as a hash function is that, given the same input, it will always give the same output
Which is why the hashCode implementation for integers counts as a hash function even though it does nothing to the data
Given the same input, you will always get the same output
wet breach
You are right it does count as a hash function 🙂
waxen plinth
What's your point then oh my god
wet breach
That base64 is a hash algorithm
waxen plinth
That's not its purpose but it technically qualifies
It doesn't really accomplish any of the main goals of hashes for either use
For data structures it doesn't reduce the size of the data or "summarize" it, it tends to make it even bulkier, which isn't useful
For security, the original data can easily be derived from it, so it's not useful for that either
And again it's not any shorter than the original data so it doesn't have any use for file verification
So it fails at every purpose a hash function usually fulfills
It meets the technical definition of what a hash function does but if it can't be used for the same things a hash function is typically used for it's safe to say it's not one
On a technical level you'd be wrong to say it's not a hash function but that's just pedantry
Nobody in their right mind would use base64 as a hash function
wet breach
It meets the technical definition of what a hash function does but if it can't b...
most hash functions have nothing to do with security
waxen plinth
They're used either for data structures or for security
Those are the two primary uses
Base64 is useful for neither
wet breach
you are confusing hash functions with security for things like checksums, fingerprints, ciphers etc
waxen plinth
Checksums use hashing algorithms
Which are just hash functions but more complicated and meant to make the original data irretrievable
Fingerprints, checksums, whatever you want to call them
They are hashes
wet breach
Checksums use hashing algorithms
no they use chechsum algorithms
waxen plinth
Checksum algorithms are hash functions
When fed the same input they will always give the same output
But they meet a few extra specifications that make them useful for security
They give fixed-size outputs, they're irreversible, and they're not nearly as fast as the hash functions used for data structures
If you're gonna sit here and tell me base64 is a hash algorithm how the fuck can you say sha-256 is a "checksum algorithm" and not a hash function
You're just trying to change the words to make it seem like you have a point but you're just giving me bullshit
wet breach
If you're gonna sit here and tell me base64 is a hash algorithm how the fuck can...
because sha-256 doesn't have parity bits or parity words
waxen plinth
It's a hash function
A specialized one
But it is still a hash function
A square is a rectangle and you're not wrong to call a square a rectangle
wet breach
therefore because of that, sha-256 is not a checksum algorithm
proud basin
<@!266226790458982412> I think the book tag is invalid

That's the problem idk what I did to get that output
waxen plinth
We're gonna need to figure that out if you want to fix the problem
wet breach
@waxen plinth you can use sha256 for the purpose of creating a checksum, but it isn't a proper checksum algorithm due the reasons I have explained
waxen plinth
So sha-256 creates checksums
But it is not a checksum algorithm
A checksum algorithm not being an algorithm which generates checksums?
Do I understand you correctly
wet breach
or you didn't read what I stated what a checksum algorithm has
waxen plinth
It's almost like algorithms can be specialized for certain things
There are checksum algorithms that do that
Wait why are we arguing about checksum algorithms in the first place
When did I ever say anything about those
I just mentioned sha-256 as a hashing algorithm that can be used for checksums
And you started spewing shit about how it's not a "checksum algorithm"
By the way
waxen plinth
The page for sha-256 literally lists it under the "checksum algorithms" category
proud basin
Thinking about it more I think this may be giving that output ```java
Book book = new Book();
Book.PageBuilder page1 = book.addPage();
page1.add("t");
page1.add("\n");
page1.build();
Book.openBook(player);````
waxen plinth
So on all counts you are a headass

Oh
waxen plinth
Why do you need to know where the hit landed on the entity then
waxen plinth
And you want it to be shown right where they hit it rather than above the entity's head?
keen kelp
where else should the marker appear
waxen plinth
Yeah there's no good way to do that other than do the math yourself
keen kelp

on top of the head you say?
what if it's like a giant
