How can I easily turn a list of these:
into a list of Location?
I could iterate over each element of the list and convert then add
but I'm guessing there's quicker syntax
tardy delta
stream them
list.stream().map(c - > new Location(someWorld, x, y, z, yaw, pitch)).collect(tolist)

nothing happends when i try this
tardy delta
why returning after you made local variables?
opal herald
idk
what did return do agan
that works
the issue i have rn is that im trying to make my have "reach" with the torch
so pretty much i want to get an explosion whereever the player left cliks
but to do that you need reach
so im trying to make the torch cause an explosion wherever i left click

player.spigot().sendMessage(MessageType.ACTION_BAR, new TextComponent(text)) and use a runnable to keep sending it

dense geyser
can someone explain in simple terms what a daemon is in terms of threads? ex Thread#setDaemon(boolean), I thought daemons were to do with docker exclusively 😅
ivory sleet
basically means background process
in Java, setting a thread daemon will make sure that the java program can terminate w/o having to await termination of the thread
(ofc the thread will terminate afterwards)
but well, in the background
opal juniper
(daemon isnt java specific though)
dense geyser
so its the equivalent of calling cancel on a bukkitscheduler task?
ivory sleet
not really
dense geyser
oh
opal juniper
Threads run seperately to the main thread of execution but all fall under one java process, so when the main thread terminates these other threads will prevent the actual ending of the java process.
Setting the daemon to true tells the jvm that it is safe to just end that thread once the main is done so that the java process can finish
@dense geyser
tardy delta
so those other threads will finish their job in the background?
opal juniper
not in the background, they will just be terminated
dense geyser
alright, so say if daemon = true and I were using Thread alongside redis pub/sub, if the thread managing redis closed, would that also close any lingering pub/sub threads?
tardy delta
ah like that
opal juniper
Yep
dense geyser
interesting, thank you ❤️
steady rapids
noob question: how do I get the nametag of a mob (not the default name)?
tardy delta
so in a normal situation those threads will prevent the process from stopping but if they are daemon threads the jvm knows that it just can kill those in order to terminate the process?
ivory sleet
myes jvm can pretty much end them whenever its plausible
dense geyser
alright, so I should just not worry about daemons rn then lol
ivory sleet
it doesnt care about code statements such as finally
so lets say you do have a connection, then you might risk to leave it open
mye
well I use daemon threads for my pubsub implementation, but thats mainly for event processing and not the pub sub itself
ivory sleet
mye a similar event bus to the bukkit one
since thats basically getting some data, process it, and invoking relevant observers
and can be completely isolated from any redis stuff
dense geyser
i see
so daemonising something like this would be a bad idea, since its just a publish?
public void publish(String channel, String message) {
Thread thread = new Thread(() -> {
try (Jedis jedis = getResource()) {
jedis.publish("channel", "msg");
}
});
thread.setDaemon(true);
thread.start();
}
thats probably a less good idea
dense geyser
alright
ivory sleet
since it may not complete that try block fully (aka calling close() on the getResource()) to lend back the connection to the pool
if we're post finish state
dense geyser
thats a good point actually, thank you
ivory sleet
tho I'd assume that you close the pool during termination in which it might be fine 
dense geyser
yes, but better safe than sorry ¯_(ツ)_/¯
ivory sleet
yeah
idk much about jedis, but I do know its blocking when invoking subscribe, so using subscribe might be worse of an idea than simply publishing, and you're only publishing
dense geyser
so daemonising subscribe is a defo no no?
vestal dome
guys why is managing block states in Spigot 1.8.8 so difficult.
ivory sleet
probably, unless it uses some internal thread that isnt daemon
but its nothing Id rely on honestly
dense geyser
interesting, alright, thank you

vestal dome
welcome to my life lol
I can give you a hand if that is your life
because I map NMS, and I can confirm bukkit over complicated the states systems in 1.8.8 or legacy versions 😂
(I map NMS for compatibility purposes, never for the purpose of replacing bukkit)
dense geyser

also
the lack of pdc in 1.8 x-x

it's called NBT.

oh well..

```java

Someone Know What should I do
tardy delta
save it
vestal dome
I would actually suggest you store the data in memory,
and when the server is shutting down save it to the file..
I had this experience where it was super slow to set values in-real-time to files in bukkit
idk why
tardy delta
a fileconfiguration is basically in memory
vestal dome
yeah but would you really like to specify every string?
tardy delta
#save is saving it to the file
vestal dome
like "player." + uuid + ".money"
everywhere?
instead you could have an Object like
"PlayerData"
that stores the money, status, rank (for example)
brittle lily
#save is saving it to the file
But I have addCoin,DeleteMoney too and they are workin
brittle lily
#save is saving it to the file
And I saved config on another class
tardy delta
why setting it to a bool too
ivory sleet
oof

Hey. Does anyone know why I can't access my library's methods even though they seem to be loaded in properly?
I'm using Maven for both projects and I exported the library using maven & added it as a dependency. I've reloaded both projects, clean installed the library, and even restarted IntelliJ. What's wrong?
First image (top) is of the library when you ctrl+click on the import, and second is of the plugin itself
kindred valley
why this happening
manic delta
Hey. Does anyone know why I can't access my library's methods even though they s...
Don't use static methods
wind tulip
is that the issue or is that just a practice
manic delta
why this happening
Just ignore
vestal dome
why this happening
ignore
fossil lintel
Hey. Does anyone know why I can't access my library's methods even though they s...
Because your code that's using your library is not in a method
vestal dome
it says that because you might of not registered the commands in plugin.yml
kindred valley
but after this shit commands are not working
manic delta
is that the issue or is that just a practice
Using a lot of static stuff causes lag
kind hatch
???
manic delta
but after this shit commands are not working
So something other than that is wrong
wind tulip
Because your code that's using your library is not in a method
The code of the library itself looks like this:
fossil lintel
Yes, the library is okay
fossil lintel
But the place where you try to use it is the issue
manic delta
since when do static methods lag servers?
forever lol
tardy delta
class names starts with an uppercase character, the compiler thinks youre referring to a variable called main i guess
manic delta
if static methods lagged, they wouldn't be used.
I said
vestal dome
NO?
manic delta
excessively
kind hatch
forever lol
Uhhh. proof?
manic delta
Not always
vestal dome
Using a lot of static stuff causes lag
.
wind tulip
But the place where you try to use it is the issue
got it, forgot you can't run code inside of a class (outside of any methods), only define variables
manic delta
Yes, a lot
vestal dome
even excessively it won't cause lag.
manic delta
it does
vestal dome
did you do the test?
fossil lintel
static methods don't lag the server, they're just usually not really good for writing reusable code modules
vestal dome
exactly.
manic delta
The server does not, but your plugin is less optimized
kind hatch
You clearly don't know what static is used for then. :/
tardy delta
@wind tulip you saw what i wrote?
vestal dome
statics are utilities for example.
kindred valley
So something other than that is wrong
why can it be
vestal dome
or singletons
wind tulip
<@545012151081893898> you saw what i wrote?
yes
wind tulip
but
vestal dome
well I feel bad for you.
wind tulip
But the place where you try to use it is the issue
this still doesn't explain why I can't import the method
the import statement itself is also giving me an error
kind hatch
What about oracle themselves?
tardy delta
also method names starts with a lowercase character
wind tulip
<@545012151081893898> you saw what i wrote?
but also I've renamed the class and before it was uppercase and still didn't work, so idk
fossil lintel
the import statement itself is also giving me an error
Yes, because importing a static method directly needs an import static
wind tulip
oh
vestal dome
or just use <class of the static method>.<static method>(<parameters>)
always works
not that import static won't work ofc
I just think it's more organized, since it actually says the class before the method.
wind tulip
wind tulip
I feel like I should keep it static then

I said in plugin optimization
Not the total server
fossil lintel
What kind of optimization are you talking about?
manic delta
response times
vestal dome
wait what?
fossil lintel
I don't think that is related to static
tardy delta
indeed
manic delta
I will search more then
vestal dome
I don't think that is related to `static`
well statics are loaded when the JVM is started and end when the JVM stops.
If I am not mistaken
correct me if I'm wrong
crisp steeple
provided the class is referenced somewhere
tardy delta
well statics are loaded when the JVM is started and end when the JVM stops.
when the class is loaded
iirc
fossil lintel
well statics are loaded when the JVM is started and end when the JVM stops.
I'm not sure about that, but that is possible, however that would be a microoptimization . I'm not sure how that would compare to creating a new instance of a class to use the method
vestal dome
well there's gotta be a point to using static.
if there's no point in using static, it wouldn't of been created.
crisp steeple
utility
vestal dome
or it would of been long removed..
crisp steeple
initializers
kind hatch
Utility is one. Another is to have something that needs to be shared between instances of the same class.
fossil lintel
Statics have their uses
manic delta
if there's no point in using static, it wouldn't of been created.
But I talked about its excessive use 😿
tardy delta
the point of static is for stuff that doesnt belong to a class
manic delta
Not just a single variable
vestal dome
I guess you got a point
quaint mantle
i like to think as static as a floating variable
it doesnt have a base, it just exists
you could explain static by saying its global
exists once
manic delta
I understand that the static things are loaded into memory at compile time and not as the lines of code in the program are executed.
||Correct me if I'm wrong||
vestal dome
are loaded into memory when the class in specific is loaded*
tardy delta
loaded into memory at compile time that doesnt make sense
manic delta
That's why I was told that its excessive use can lead to less response time or poor optimization.
manic delta
Im not, but I understand that it works like that (That's what someone taught me lol)
vestal dome
||hope it wasn't a school|| it definitely wasn't.
manic delta
Nope

maiden acorn
anyone have any ideas on the best way to force a player's client to re-request a chunk?
or, alternatively force the server to send an entire updated chunk (rather than individual blockChanges) so the client reloads the entire chunk?
maiden acorn
ah, perfect... that solves one of my problems!
the other is that I'm sending a decent number of block change packets to players... I notice some of the world methods allow you to request changes and have them queued (like unloadChunkRequest(...) instead of unloadChunk(...)... does anything like this exist for block change events? I'm trying to spoof a pretty large structure and would prefer to queue these events instead of sending them all at once
ebon coral
When did they add the ability to send plugin messages just through Bukkit.getServer()? Literal blessing lol
wet breach
the other is that I'm sending a decent number of block change packets to players...
you will probably have to create your own mechanism that prevents sending it all at once. The reason a queue exists for unloading chunks is because MC caches recently loaded chunks as well as a chunk could be valid still in being loaded. So the queue exists for the server to recheck if it can unload it.
maiden acorn
gotcha, that makes sense
upper crater
what's the easiest way to make a config folder like the one viaversion has?
kind hatch
By using #saveDefaultConfig()
upper crater
By using #saveDefaultConfig()
reloadConfig() overwrites the current config file with default right?
Also, if the file doesn't exist, does it just make it?
kind hatch
#reloadConfig() updates the cached version of the config by reading what is on the disk.
Yes, #saveDefaultConfig() will create the file if it doesn't exist.
upper crater
how often should I do reload config
and does savedefaultconfig have a different file than saveconfig?
kind hatch
Depends on your usecase. Normally, you would only need to call it if you are making changes to the config file manually. Usually implemented with a reload subcommand.
#saveDefaultConfig() will look for a file called config.yml in your plugin jar and then write it to disk if it doesn't already exist. That's all it does. It's the same exact config that's returned with #getConfig().

The path #saveDefaultConfig() uses is the parent directory of the compiled jar. So maven will take all of the resources from /src/main/resources and put them in the parent dir of the jar. (This can be changed of course, but it's default behavior)

There's not. You'll have to check for a few events in order to cover the full functionality.
InventoryClickEvent - Check to see if the player shift clicks armor in their inventory.
InventoryDragEvent - Check to see if the player manually moves the armor to the armor slots.
PlayerInteractEvent - Check to see if the player equips the armor piece from the hotbar.
Alternatively, you could use this resource: https://github.com/Arnuh/ArmorEquipEvent

yea
kind hatch
Player interact event and Player interact at entity event
If you want to check if the player is right clicking an entity, use the PlayerInteractEntityEvent
If you want to check if the player is left clicking an entity, (effectively damaging it) use the EntityDamageByEntityEvent
sharp flare
I'm not damaging it
i left click the staff after right clicking an entity
but then it triggers both at the same time when i right click an entity
so entity damage event is not applicable here

theres a lot of them as well

as theres also a ton of blocks that dont equip the armor when you right click
kind hatch
but then it triggers both at the same time when i right click an entity
Well it's likely that you aren't using the right event or that your checks are slightly off.
What version are you using? Because the player interact event can fire twice if you don't check the hand the player uses. Since we have two hands.
sharp flare
have u checked the 2 pictures above?
I'm explicitly checking the action and hand there
player interact at entity event only has hand checks unlike the player interact event
kind hatch
Sorry, I thought the names were MAIN_HAND and OFF_HAND, not just HAND.
Maybe that's for inventories.
sharp flare
isRightHand for player interact event, the second picture is not reference inside a variable
crisp steeple
entityinteractevent gets fired twice for some reason
a lot of servers have that bug
sharp flare
based from the checks it shouldnt be even triggering left click when I right click an entity
crisp steeple
or maybe its intentional with how clicking it works
sharp flare
so it might be the case with player interact at entity event not having appropriate #getAction checks
crisp steeple
i dont think thats the case
sharp flare
would gladly accept a reason why if its not
sharp flare
a lot of servers have that bug
so its a server side?
crisp steeple
no
kind hatch
Doubt it.

Alright, so let me see if I understand fully.
You have a staff that you need to right click an entity with first. (That's covered by the PlayerInteractEntityEvent)
The player can then left click on either a block or in the air to activate the ability of the staff. (PlayerInteractEvent)
Is that correct?
sharp flare
correct
kind hatch
Ok, so then it comes down to how you check for things.
sharp flare
when right clicking the entity it then triggers the left action in the player interact event
these doesn't happen on some servers but on my local one it does
kind hatch
Then you probably need more checks in your PlayerInteractEvent.
Like, staff state and whatnot.
It may also help to break up your if statements.
if (!(stick instanceof AbstractStaff)) {
return;
}
if (!(event.getRightClicked() instanceof Player)) {
return;
}
// etc
crisp steeple
ok so
you are never left clicking
and somehow it ends up firing a left click action playerinteractevent?
sharp flare
yeah
exactly
its damn weird
but since they are both interact events idk why though
kind hatch
It's likely an issue with just one of them.
Something unaccounted for.
Can you share the code for both events?
?paste
undone axleBOT

https://paste.md-5.net/letesutayo.java

kind hatch
That's true.
sharp flare
wdym
kind hatch
He only needs left click for the player interact event.
sharp flare
fair
kind hatch
That, but also he stated that players will left click with the staffs.
crisp steeple
yea
sharp flare
I'm just making it more readable though but ill take that
kind hatch
Well, are there different types of staff implementations? Because you could make another event and just check if it's a different staff. A little redundant, but guaranteed to work.
sharp flare
only have entity staff implementations
kind hatch
Well you may want to split your logic up like this then.
if (!(stick instanceof AbstractStaff)) return;
if (!(stick instanceof EntityStaffImpl)) return;
if (!isRightHand) return;
if (isRightClick) {
// do right click things
} else {
// do left click things
}
then any staff that doesn't implement entitystaff aint gonna work
kind hatch
But you said that's all you have to work with. :3
sharp flare
but thats good for a seperate listener
Not sure if u mean staff implementations but entity staff is just an interface
kind hatch
Yea, I was asking if you had other ones that you were going to check for.
Cause if that's the case, you could just copy the listener and change the one check.
sharp flare
no actually, thats why I have instance of check in the if conditions
kind hatch
So what's the issue with just checking if all staffs are not an instance of EntityStaffImpl?
It would still meet the criteria would it not?
sharp flare
I would have to move the #onClick method above for abstractstaff only
if im using ur code above
cuz I dont have in mind of making seperate listeners for this
when the checks are on time and should not be even triggered when i right click
Appreciate your time though ill be heading out for now

Because a double is ambigous.
You should never do something like
double x = ...;
if(x == 0.0165) {
}
You should always have an epsilon value.
private static double EPSILON = 1E-12;
double x = ...;
if(x - 0.0165 < EPSILON) {
}
Yeah sure. By like 7% of the playerbase (constantly shrinking)
supple elk

what does this actually do 🤔
I'm guessing it's needed cause of rounding errors
but how does the epsilon help?
wet breach
it dictates how many places from the decimal is acceptable
the ambiguity comes in when you have CPU's that support varying levels of floating point values
supple elk
I see
I guess I could store an int and just the number of ticks instead
I'm working with time
supple elk
I only need it as a number of ticks
Making a racing game
Using a runnable for number of ticks is probably more accurate for timing anyway
cause server lag won't be counted then
wet breach
probably a separate thread would be better but again depends how accurate you need it to be
runnable won't guarantee accuracy. Runnables are affected by lag
supple elk
ik, the point is they are affected by lag
wet breach
if there is lag, the longer it takes to get to the task for the runnable. Unless the runnable is running in a separate thread
supple elk
say the server is lagging and a player goes around the track
it will take longer for them to get around than if the server wasn't lagging
so if the rate at which the runnable counts is also effected by the lag, and is just counts the number of ticks, it takes the lag into consideration so is more accurate
effectively the time isn't affected by the lag as the player also lags
at least that's my theory

getting a typecast error
fossil lintel
You'd need to use List<String> instead of String[] in your HashMap declaration
An Object[] is a primitive Array in Java. List<Object> is a data structure that internally probably uses []
granite owl
yea ofc its just a wrapper that re-declares its primitive array internally
with the new size
but the return type of .toArray() is Object[]
so i thought i could upcast the object array to a string array
sec lemme check
ill prob just declare my own array with the size of the arraylist then if thats not working
tender shard
but the return type of .toArray() is Object[]
just use toArray(T[]) or use a Stream.toArray(IntFunction)
fossil lintel
Oh ofcourse, I missed that part. Yes, the toArray() returns an Object array because Java removes the generic (<String>) information while compiling. This makes it impossible for the JRE to know the actual type of the Array it should build during runtime
as @tender shard said, toArray(new String[0]); will probably give you the right primitive array type
You can just create an array with an empty size in this case. It will only use it for the type lookup
