it is quite possible the obfuscator is the key here
it is most likely an obfuscator specific thing and not the compiler
slender elbow

pretty sure if they looked at the class file after compiling, they would see that bytecode doesn't exist in the class đ

Emily can u return and update the 1.8 api
wet breach
not even the appropriate formats for them either

azure zealot
you haven't shown a single bytecode
I have showed you the fast iload instruction with the value
azure zealot
send a class file that uses the instruction and passes the verifier
In some jvms you need to enable noverify
How do java read and execute it if its not in the bytecode
dry hazel
it's a hotspot thing
if hotspot without verifier runs it, it doesn't mean it works everywhere else
azure zealot
You can run it as every other instruction
Test it yourself
You dont need to believe me
Im just telling you it will work

wet breach
Im just telling you it will work
there is a lot of things you can put in the class file that the jvm will just ignore
dry hazel
you literally turn off the verifier and rely on an implementation detail
azure zealot
Yeah
dry hazel
you can't just use it like any other class
azure zealot
You dont need the verifier at all
azure zealot
you can't just use it like any other class
Why not
wet breach
You dont need the verifier at all
clearly shows you don't even know what verify does
wet breach
for those that don't know, I highly recommend not using that jvm arg at all
dry hazel
you have to explicitly turn off the verifier on the command line
and even then, people might have a different jvm impl, which will explode
azure zealot
you have to explicitly turn off the verifier on the command line
Yeah or you do it with the unsafe
azure zealot
for those that don't know, I highly recommend not using that jvm arg at all
You shouldnt thats right
wet breach
but the fact you need to disable the verifier to make your code work, already means that whatever you are doing is not part of the specifications
azure zealot
But in fact you can
azure zealot
but the fact you need to disable the verifier to make your code work, already me...
Thats right
As i said
Its not documented as valid instruction
wet breach
no as the experts have said, it doesn't exist whatever you are talking about in the official JVM
so either what you are doing is being ignored by the JVM or you are running a non-official or non-speced JVM
azure zealot
It will execute the code
azure zealot
Please try it yourself
wet breach
Thanks, I needed that verification
wet breach
Please try it yourself
I have no interest proving something that doesn't exist in the official specs. I already know the outcome on my system of what will happen or two possibilities
either my JVM dies or the JVM is going to ignore it

What is better when creating an api, passing copies of objects or giving them directly?
ivory sleet
How large is your code base?
upper hazel
why this question
ivory sleet
why this question
It can sometimes be more reasonable for larger code bases, to split certain module layers with a separate api layer where the api isnât directly implemented, but instead it wraps around whatever it needs to serve its contract
upper hazel
I mean that an object is registered through a special class and I donât know what will happen if the developer works directly with the object without registering it, but at the same time nothing will happen if the registration class does not directly link the object data and the object itself
upper hazel
It can sometimes be more reasonable for larger code bases, to split certain modu...
what do you mean, what does this have to do with it, are you telling me about the interface?
ivory sleet
You asked about passing copies or direct objects, maybe I interpreted it wrongly, if you just meant the collections in particular
upper hazel
I'm talking about getting and setting data objects directly or through a copy
inner mulch
Does bukkit have an Eventhandler for every Event or does the event get published to one which then proceeds to Check which method is looking for what Event?
ivory sleet
I'm talking about getting and setting data objects directly or through a copy
Well it sort of depends, like both has advantages and disadvantages
buoyant viper
so i did some digging and the only non-hotspot related mention of "FAST" instructions are in an internal class presumably relating to the Verifier
ivory sleet
Like ZlataOvce said I believe
Tho I do think going by immutability by default is a good mindset unless you need mutability for w/e reason (which implies copies to some degree)
buoyant viper
im personally going to start using _shouldnotreachhere in my bytecode
upper hazel
Well it sort of depends, like both has advantages and disadvantages
That's why I'm asking what is better when creating an api, provided that the object is registered through a class that binds and hashes the object data
buoyant viper
should i do it? or is it not worth the effort
nah, reflection = slow
jk
(kind of)
theres always weird hackery to alleviate perceived slowness for it though, like MethodHandles and that godforsaken LambdaMetaFactory class
dry hazel
methodhandles are pretty fast
buoyant viper
the chain is like,
Method, MethodHandles, LambdaMetaFactory, Direct Invoke
iirc
"slowest" to "fastest" that is
not a big fan of LMF itself though, im a little stupid and getting MethodHandles to work is a feat in and of itself for me sometimes
sometimes the param types just DO NOT like me
ivory sleet
Wasnât reflection also reimplemented with method handles or something like that in a newer jep

buoyant viper
yea ;p
fluid river
you need a buffer of fixed length in both languages
azure zealot
do it the unsafe way! xd
fluid river
which you use to read and write data
well, you can use object = null and then call System.gc()
not like it actually does that
azure zealot
isnt this possible with weak references or something?
fluid river
but at least it's close
ivory sleet
isnt this possible with weak references or something?
That doesnât really force it
fluid river
it also calls finalize() so you can have a "destructor" code
azure zealot
not force but i till be gced very fast
ivory sleet
I think java has the foreign mem and func api in j22
fluid river
well, you can use object = null and then call System.gc()
.
azure zealot
and evry weak ref would be collected
ivory sleet
it doesnât really force
azure zealot
so ist acctually forced
ivory sleet
its more like a request
fluid river
well it does, but it requests to gc, not performs it
ivory sleet
And a lot of apps disable system gc
fluid river
i mean this would work fine:
buoyant viper
meanwhile the Minecraft client calls System.gc() in at least 7 different locations fairly frequently (jesus fucking christ mojank WHY)
fluid river
public static void main(String[] args) {
MyClass m = new MyClass();
m = null;
System.gc();
}
public class MyClass {
@Override
public void finalize() {
System.out.println("I'm erased");
}
}```
hybrid spoke
```java
public static void main(String[] args) {
MyClass m = new MyClass();
...
that doesnt clear the object
it just suggests to gc
50/50 chance that it does
azure zealot
thats why a said you could use weak references only xd
ivory sleet
it just runs it instantly
Not always
fluid river
```java
public static void main(String[] args) {
MyClass m = new MyClass();
...
this exact code always works
and i get the console message
hybrid spoke
this exact code always works
it also works without the System.gc because its the end of the program
azure zealot
yeah but thats agasinst the use of weak references lol
fluid river
it also works without the System.gc because its the end of the program
yeah but anyways
azure zealot
if you want it to get gced you can code it that way
hybrid spoke
if you want it to get gced you can code it that way

hybrid spoke
what the hell is this
I apologize if there's any confusion in my response. It appears that there might be an issue with my interpretation or the code example provided. Let me clarify and correct any mistakes.
In network programming, when you read from a stream, you typically get back the number of bytes read, which can be used to determine the length of the received data. However, in the example provided, the specific values for lengths and content are arbitrary and simplified for illustration.
If you have specific concerns or questions about certain parts of the code or if you could provide more details about what you find confusing, I'd be happy to help clarify and address any issues.
hybrid spoke
since russian youtubers would get money otherwise
thats so dumb
fluid river
> I apologize if there's any confusion in my response. It appears that there mig...
ask him what do 0 and length in the end mean
hybrid spoke
I apologize for any confusion. The 0 and length in the code snippet I provided are placeholders for actual values that you need to determine based on your specific implementation.
Let's take a closer look at the relevant parts:
csharp
// Read join packet
byte[] joinPacketBuffer = new byte[1024];
int bytesRead = stream.Read(joinPacketBuffer, 0, joinPacketBuffer.Length);
string joinPacket = Encoding.ASCII.GetString(joinPacketBuffer, 0, bytesRead);In the Read method, 0 represents the offset within the joinPacketBuffer array where the data should be placed, and joinPacketBuffer.Length represents the maximum number of bytes to read. The bytesRead variable then holds the actual number of bytes read from the stream.
Similarly, in the Write method:
csharp
// Write allow join packet
byte[] allowJoinPacket = Encoding.ASCII.GetBytes("AllowJoinPacket");
stream.Write(allowJoinPacket, 0, allowJoinPacket.Length);Here, 0 is the offset within the allowJoinPacket array from where to start writing, and allowJoinPacket.Length is the number of bytes to write.
These values depend on the specific requirements of your protocol and the data you are exchanging between the client and server. You may need to adjust these values based on your actual packet format and size.
fluid river
is that like length of the message to read
and 0 is smth i don't know about
why do i need an offset?
isn't stream flushed or smth?
fluid river
> I apologize for any confusion. The 0 and length in the code snippet I provided...
ask if i can flush stream every time so i don't use offset?
since ig if stream is not flushed, i would once reach the end of byte array
hybrid spoke
Flushing the stream won't eliminate the need for an offset. The offset parameter in the Read and Write methods indicates the position in the buffer from which to start reading or writing data. It is crucial when you're dealing with partial reads or writes.
If you're always reading or writing the entire buffer, you can set the offset to 0, and it will work effectively as if you didn't use an offset. However, if you have scenarios where you're reading or writing a portion of the buffer, the offset becomes significant.
Here's an example with the offset set to 0:
csharp
// Read join packet
byte[] joinPacketBuffer = new byte[1024];
int bytesRead = stream.Read(joinPacketBuffer, 0, joinPacketBuffer.Length);
string joinPacket = Encoding.ASCII.GetString(joinPacketBuffer, 0, bytesRead);// Write allow join packet
byte[] allowJoinPacket = Encoding.ASCII.GetBytes("AllowJoinPacket");
stream.Write(allowJoinPacket, 0, allowJoinPacket.Length);In this example, it's assumed that the entire buffer is being used, so the offset is effectively 0.
Remember that flushing a stream is a different concept; it's about ensuring that all the data in a buffer is written to the underlying stream. It doesn't eliminate the need for an offset in the Read and Write methods, which is more about specifying where in the buffer to start the operation.
fluid river
so i won't be able to send or receive any more messages
alr so i can just use 0 all of the time for my purpose
but is stream flushing automatically?
since i can't find a Flush() method

not after normalized

i did that but then the fallingblocks went all over the place, they went flying past the target
worldly ingot
If you're aiming for a specific block, you're going to have a hell of a time. Velocity's actual metrics are pretty undocumented so a velocity of, say, 3, isn't going to launch it 3 blocks
dry forum
so theres no "simple" way to launch a falling block to a location?
worldly ingot
A very specific one? No, not really
Best way is probably to fake it if I'm being honest. Just teleporting it on a loop in small increments over a predefined path
(and by "predefined", I mean calculating an arch between two points - which you'll need to look up the math for)
dry forum
welp that sucks
worldly ingot
Yeah, but the alternative is velocity which is rather difficult to predict
If your increment is small enough, the teleports are interpolated so it should still look relatively smooth

what's the best class to use for random numbers and chance system?
eg. I have an item with 5% chance to be caught
using Random for this would be ok but if I generate an int between 0 and 100, everything has an equal chance to be generated? for 0, its 1% to be generated, for 1 its also 1%, etc..
would it be ok to develop a system where actually
a number 0 would have 0% to be generated,
a number 1 would have 1% to be generated
....
but this is where I'd run into issues so instead, I though:
how about I develop a system where
numbers between 0-10 have 10% to get caught
numbers between 11-20 have 20%
numbers between 21-30 have 30%
numbers between 31-40 have 40%
numbers between 41-50 have 50%
and numbers above 50 have 50%
... something like that?
tender shard
for 5% just check if the random number between 0 and 100 is <= 5

umbral ridge
for 5% just check if the random number between 0 and 100 is <= 5
but would that be ok? I guess its 5% likely that the number between 0 and 5 will be generated? or is it an equal chance? It's kinda confusing
it's like.. every number has an equal chance to be generated, between 0-100
so is 5%, numbers in range 0-5 really 5%?
remote swallow
why wouldnt it
umbral ridge
It's not like higher numbers will be generated more often? (higher numbers have a higher chance to be generated). numbers will just get picked randomly between 0-100
1 can be generated with the same chance as 100
so 1% is equal to 100%
remote swallow
no
umbral ridge
yes
remote swallow
if its 0-5 you get a 5% if its 0-90 you have a 90% chance
umbral ridge
hmmm
remote swallow
because theres 5 different numbers that could be generated for it to be that
if it was only 1 number to pass, that would be 1%
because its 1 number out of 100 to get that
umbral ridge
I guess yeah... fair point
remote swallow
but then if you wanted it 100 out of 100, theres 100 numbers it could be

You are sending packets to make the player believe another player is standing there while the server has no idea about that.
But adding the entity to the world makes the server actually aware of that entity (which will result in the server ticking the entity)

You are changing the type on target then overwriting it with a state update
a BlockState is a snapshot of the Block. It is not live
If you call update on a BlockState it will push teh snapshot data to the live Block.
if you want teh client to see an update you will likely have to delay your state.update a tick

pliant kite
doesn't do anything
river oracle
Well it should
young knoll
I donât think the repeater itself needs an update
I think the block that would be powering it does
pliant kite
wouldn't updating the repeater make it check if it should be powered or not?
im trying to make this work for more than just repeaters too so i dont want to just case it out and update the back face of it
young knoll
I think redstone components update their state in onNeighbourChanged
lost matrix
I think the block that would be powering it does
Ah yes. Lets path trace the power to its source and update it /s
pliant kite
lol
lost matrix
Next idea: Lets create a clean new BlockData from the blocks material, apply the rotation and then update the block.
If that doesnt work we enslave coll to write a pr
young knoll
I have a feeling thatâll make it always unpowered after rotating
Even if the new placement should be powered
lost matrix
Yes there is a high probability of exactly this happening
pliant kite
I think redstone components update their state in onNeighbourChanged
would updating a block around it work?
maybe the block below it, since that will always be a block
lost matrix
You can try simply updating all 6 ordinal directions
Youll hit the power source then for sure
pliant kite
im trying to think of other cases besides repeaters and comparators where this is going to be an issue
i think thats kind of it actually
lost matrix
I dont think there are any other powered blocks where the rotation is of importance.
pliant kite
wire doesnt have rotation
lost matrix
I thought about that, but the powered state doesnt rely on its connections
pliant kite
it has directions
like booleans for cardinal directions
like walls
im only dealing with Directional, Rotatable, and Orientable blocks
holy fuck i did it
pliant kite
maybe the block below it, since that will always be a block

target.setBlockData(data, true);
Block below = target.getRelative(BlockFace.DOWN);
BlockState belowState = below.getState();
below.setType(Material.BEDROCK);
Bukkit.getScheduler().runTask(Bleef.plugin, () -> belowState.update(true, true));
``` this seems so wrong but okMojank

appreciate the help
echo basalt
help I made an impulsive purchase
tomorrow I'm upgrading my pc's ram to 64gb 
I can finally open like 19 intellij windows and like 2 chrome tabs
pliant kite
```java
target.setBlockData(data, true);
Block below = target.getRelative(BlockF...
doing this (updating adjacent blocks) makes the block you update flash
for a tick
and its ugly af
rough ibex
depends on how you register them in the first place
flat olive
Because I dont like typing /gamemode and seeing on tab stacked /gamemode and /Gamemode
I want my aliases hidden
Does that make sense?
Please help me
flat olive
I thought commands were case insensitive
how can I make them not case insensitive?
It gives an error once they type a capital or something in the first argument
rough ibex
I didnt know they werent already
flat olive
thats why I added aliases with a capital
rough ibex
Okay so just dont
flat olive
yeah its very odd
rough ibex
Dont type Gamemode?
flat olive
I know but if someone were to type the command I want the caps to not matter for the command and it to work
it makes the command more unique
rough ibex
Make some kind of command preprocessor then
flat olive
thanks for this, case insensitive I was looking for these words
rough ibex
lowercase command
icy beacon
by definition of unique a command with multiple aliases is less unique than a command with no aliases
i'm just picking on words
rough ibex
Truth
flat olive
True
I wish it wasnt case sensitive and didnt give an error
sorry
don't mean to make a commotion, thanks for your help though..

i made the plugin using intellij
i made a plugin but, i cant seem to get it working
can someone please help me
agile anvil
Do you have any errors? Logs? Indication about what is "noy working"?
grave terrace
no
grave terrace
Do you have any errors? Logs? Indication about what is "noy working"?
wait i do
idk what it is
agile anvil
Tell us what was your step, what you did, where you're stuck, ...
plucky rock
does any1 happen to know how I would push the plaeyr straight up
if (attacker instanceof Spider) {
if (AttackerName.contains("§5King of Spider's Servant")) {
Vector up = new Vector(0, Playerloc.getDirection().getY(), 0);
up.normalize();
up.multiply(5);
player.setVelocity(up);
player.sendMessage("Debug3");
}
}```
this is what i have
shadow night
Oh no, uppercase variable, checking mob by name?
plucky rock
yeah
is there a better way to do it?
i assume yes
but i aint that smart
also im very new to this
this is ~3rd day
would any1 be able to explain how vectors work?
i mean i get its direction and magnitude
ive done physics
but like
in code
how does it work
im my head i assume this would work
but
it doesn't
also im not getting any errors
i dont want to be spoonfed as i kinda want to learn
agile anvil
Why are you making a vector with the player.getDirection().getY(), then normalizing (which mean the norm of the vector will be 1)?
agile anvil
What you're trying to do is push the player 5 blocks up?
plucky rock
yeah
agile anvil
Then create a Vector with 5 on the y, and apply it to the player with the #setVelocity as you did
agile anvil
If you only want a jump then x and z should remain 0
plucky rock
if (attacker instanceof Spider) {
if (AttackerName.contains("§5King of Spider's Servant")) {
Vector up = new Vector(0, 5, 0);
player.setVelocity(up);
player.sendMessage("Debug3");
}
}```this is what i have
agile anvil
Imagine your vector as the arrow showing where the player should jump
agile anvil
Should
plucky rock
i tried it
agile anvil
Have you tried ?
plucky rock
and its not
agile anvil
Please then try to get the player's velocity as based vector. And set the Y to 5.
plucky rock
hm
ok
alr trying it
give me a few seconds to test
if (attacker instanceof Spider) {
if (AttackerName.contains("§5King of Spider's Servant")) {
Vector up = new Vector(0, 100, 0);
player.setVelocity(player.getVelocity().add(up));
player.sendMessage("Debug3");
}
}
``` stilld oesnt workchanged number
to see if it was noticable
but it just doesnt change the velocity
grave terrace
@rough ibex pls check your dms
plucky rock
who ate his butter?
agile anvil
Try
Vector up = player.getVelocity().setY(5);
@agile anvil pls check your dms
agile anvil
<@318130333025435674> pls check your dms
I don't get dms, please describe your issue here
grave terrace
how?
plucky rock
if (attacker instanceof Spider) {
if (AttackerName.contains("§5King of Spider's Servant")) {
Vector up = player.getVelocity().setY(100);
player.setVelocity(up);
player.sendMessage("Debug3333");
}
}``` still dont work changed msg to make sure made it 100 cause i thought 5 might not be noticablesoo
at this poitnt i have no clue
this is a EntityDamageEntity event
so there is some velocity due to the kb on getting hit
