I thought of adding a player to an arraylist when they join but Idk if there is a better way to do it
dim bronze
i personally find it easier to have the server run inside intellij unless it's not possible
remote swallow
that probably is, just seeing if i can make it not need me to copy the stuff into ij
untold patio
so yeah a hashmap might be better
Well, Imma go read the documentation, I'll be back then
c;
ivory sleet
gl :)
dim bronze
?
dim bronze
it's not exactly checking it
it's so it will make sense when G and B are used as return types in the abstract class
sterile token
I mean i understand generics, but no that complicated
dim bronze
its a builder so it returns itself
sterile token
oh ok
dim bronze
but itself is B (when extended)
sterile token
sorry i didnt know hard generics, i just know simple ones
untold patio
Ok, so according to what I just read, the hashmap (for creating a homes plugin) should receive the player name as key, and the home as value?
Oh
Why not name?
I know UUID is an identifier but I thought I could use name
Ohhh
ivory sleet
lets say morice_0 switches their name to Conclure in minecraft
now they would have access to my homes
dim bronze
also storing the player as the key isn't great because the object changes if the player relogs
untold patio
Ohhh alright
untold patio
also storing the player as the key isn't great because the object changes if the...
Then player should be the value?
worldly ingot
Technically speaking if it's in a Map it won't matter because maps are based on hashCode() and equals(), which check the UUID
but ye
untold patio
Uuid the value
dim bronze
Technically speaking if it's in a Map it won't matter because maps are based on ...
oh? i've had the problem in the past
dry forum
whats the best way to let a plugin work with bungee & spigot? should i make a module for each or smthn
dim bronze
maybe that was an offline server
worldly ingot
They won't == each other, but they will equals() each other
worldly ingot
Yes
dim bronze
must have been using an offline server then
ivory sleet
well, you mean like getting a specific player?
untold patio
Hmmm, I guess... because a home must be only a player's
dim bronze
well you'd want some commands for this to work
remote swallow
What would be the best way to get a specific string a stringlist
untold patio
well you'd want some commands for this to work
Yes, but are the hasmap key and value alright?
dim bronze
What would be the best way to get a specific string a stringlist
explain?
untold patio
This is my home class
remote swallow
explain?
eg i have 5 different strings on a string list in config (getting from #getStringList) and i wanna try and pick a random one out of the list so would need to get a specific one
dim bronze
random number between 0 and the length of the list exclusive?
remote swallow
okay
ivory sleet
Technically speaking if it's in a Map it won't matter because maps are based on ...
Yeah for most part it Player is doable, unless you'd have to access the player extremely early like in async prelogin
sterile token
also storing the player as the key isn't great because the object changes if the...
Also, you are losting resources
Because you are using* a big object for no need
dim bronze
that objects in memory anyway
sterile token
that objects in memory anyway
Yeah but having it as key in map is even more mem
ivory sleet
Yeah but having it as key in map is even more mem
na
the Player is alr in memory
sure if you use the map past a single player's session, then you might have it filled with old player objects
dim bronze
only a reference to that memory is stored in the hashmap
just realised that its hash is never stored :P so what i said was wrong
eager knoll
Can I reference things in the config.yml of a dependency in my plugin?
sterile token
Can I reference things in the config.yml of a dependency in my plugin?
what?
dim bronze
yes but you probably shouldn't
ivory sleet

in a HashMap?
sterile token

golden turret
I am experiencing a bit of lag when trying to use the Random like 100k times at once
It is for a reward system
the player can open all of his keys at once
golden turret
yes
ivory sleet
hmm so, well have you tried SplittableRandom
golden turret
nop
ivory sleet
idk if its any faster, (usually used with parallel streams and stuff) but iirc its quite fast
golden turret
hm
but like
I use things like Collections.shuffle
and SplittableRandom does not extends Random
so I cant use it there
dim bronze
I use things like `Collections.shuffle`
if you aren't using every item in the list, collections.shuffle is quite an expensive call
golden turret
Well I am
dim bronze
then nevermind
golden turret
ivory sleet
wizardly
you could shuffle the collection in another thread
ofc it complicates things
remote swallow
For some reason essentials.getUser(Player).getNick(false, false) is returning them with suffix and prefix even tho it has the 2 false's, im so confused why
ivory sleet
like collection thread safety
anyway here
splittable is 3-4 times as fast
compared to normal
score is in nano seconds per operation
.5 in error (for splittable)
dim bronze
is there any need for a while true there? seems like a lot of iteration
golden turret
it is to be sure that there will be a reward
ivory sleet
alr, maybe try to copy paste the shuffle method
but with a splittable random
and if thats still not enough, maybe use another thread to do it
dim bronze
couldn't you scale the chances so that only 1 random call needs to be made?
its too late for me to think how
its just a weighted random
ivory sleet
yea that too
dim bronze
its taking so long because you may have small chances
there is absolutely no need to iterate more than once to get the correct reward
i have always used a treemap in the past to save iterating each time
ivory sleet
because the type passed doesnt matter Id assume in this case
golden turret
generics
rare rover
ivory sleet
I mean
CrateReward<?> is a supertype of CrateReward<A> and CrateReward<B> which is probably why they return a term of that type
golden turret
the generic for the CrateReward is to specify the reward type
winged anvil
is there a way to get the plugin version specified in the plugin.yml
winged anvil
ty
ivory sleet
can be retrieved through Plugin
winged anvil
yes
golden turret
yo
just remembered
the getRandomReward
is called 1m times
because the player can open all of his keys at once
so even if I use the weight thing
it will be called 1m times
golden turret
I think it is possible
ivory sleet
yeah, just pool the threads tho
(I assume a cached thread pool would be fine here [maybe with a max size configured on ur own tho])
ivory sleet
uh
I was thinking that you call necessary getRandomReward calls in CFs
CF.supplyAsync(() -> {
...
}, pool)
golden turret
nha
ivory sleet
cuz that there isnt async at all
ivory sleet
no but like completedFuture() is the issue
because it just takes a value a returns a dummy future that wraps the value
ivory sleet
hmm well, you could use whenCompleteAsync
but arent there parts that you wanna do sync?
like the inventory stuff
golden turret
only this needs to be sync
ivory sleet
yeah guess you can send that to the bukkit scheduler then
anyway you dont need to use the future before
from what it looks like
golden turret
the future is for the animation stuff
so when the animation ends
future.complete()
ivory sleet
alr
golden turret
cool
moved it to async
and it is very fun
seeing this literally every time
1 million rewards ๐คก
golden turret
yes
ivory sleet
ah damn
that might be hard then
I mean either way, 1mill rewards are a lot to process
golden turret
yes
I am talking with the client about it now
he said that a play may have 100k keys
imagine a server with 30 players and each player opening all of their keys at once
ivory sleet
yeah
there are certain tricks you could use
lets say the rewards vary from the command
/hello dodo
and
diamond
you could simply map the rewards to the amount of times they've been drawn
ivory sleet
and for commands, you might just wanna limit it, lets say they unlock a permission, that should only happen once
golden turret
imagine sending 1 million messages
golden turret
oh boy
the client will need to think better then
I was thinking something like
100 keys
or 50
but he is thinking about 100k ๐
ivory sleet
and for commands, you might just wanna limit it, lets say they unlock a permissi...
.
for money, count that to and execute the pay function only once
winged anvil
wow
golden turret
the problem is that the command can be literally anything
golden turret
and i dont want to write something to read what the command is
I have a /crate items too
to see your items
ivory sleet
because well... 100k is a lot to expect
golden turret
imagine having 100k items
winged anvil
actually, nvm
golden turret
I think the only way would be writing a helper method
ivory sleet

problem you are most likely encountering is invoking a new random instance that many times
you really don't need a new random instance
instead make a random instance, and then just call Random.nextInt()
golden turret
I was using ThreadLocalRandom.current()
wet breach
only time you really need a new random instance is if you need something close to true randomness
wet breach
I was using ThreadLocalRandom.current()
threadlocal doesn't do anything if you are already on the main thread. It is used if you have multiple threads and want those threads to create the random instance from their thread and not the main thread
so creating a random instance outside of your code so those code blocks can get an instance and then re-use that instance. It should help alleviate some lag ๐

Hi, anyone know how I can set to run a command (from console) in a HoverClick event?
Example:
if(player.hasPermission("hi.hi)) {

msg.setClickEvent(Here the console makes the command /hi, for example);
player.spigot().sendMessage(msg);

you can make a command that just redirects to console

you are only saving one home per player

the hashmap relates a uuid -> Home
you can either use a list of homes as the value in the map, or create your own user data class which contains a list of homes

When I click on the text (made with TextComponent) I want the console made a command (without create a new command contenent Bukkit.getServer().getConsoleServer() etc).
Is it possible?
dim bronze
yes, assuming you mean ArrayList<T>
dim bronze
Yeah,
although convention says that you should just use the type List<T>. There's no need to expose the actual implementation of the collection, just knowing that it's a list is sufficient enough to use
Seeing people use notnull annotations in java makes me happy
if you have that mentality maybe you should switch to kotlin ;)

@dim bronze Is the question ok?
hasty prawn
You want to run a command that doesn't exist?
dim bronze
Yeah, I think morice answered it nicely though
but it needs to be executed when the text is clicked, which would require a command to be run
rocky tree
You want to run a command that doesn't exist?
No, for example: /kit nameofkit nick
rocky tree
No, for example: /kit nameofkit nick
but executed by console
hasty prawn
Oh
I think you'll probably have to add another command that does basically the same thing but only Console can run
Or add another argument telling the command that console is running it
dim bronze
The more important question is why does the console have to run it?
hasty prawn
I assume to bypass cooldowns
dim bronze
If you are giving players the permission to use the command through text, surely they should just have permission to run the command?
rocky tree
If you are giving players the permission to use the command through text, surely...
I have to do this with LP, like a contract system, so I made /contract crepppy hi.hi and console when you click on the text add u group hi.hi
yeah, but in every case I have to pass it on clickevent
because it happen when u click on the text

recently switched to mongo now smh
doesnt
dim bronze
it has its uses for relational data
but most of the time when making plugins you're dealing with data that is better modelled by a document
that with relations
tardy delta
doesnt it also perform better in terms of performance when you have a big database?
tardy delta
in one that's fucked up
dim bronze
mongo is going to be a lot slower at 'table joins'.
tardy delta
dont want to try that and dont need it anyways
dim bronze
and because all of the information is generally stored in one document rather than multiple because joins don't fit the mongo workflow, you tend to get larger packets sent to the user
of course, this is why graphql is fitted nicely for querying mongo databases

please ensure me PlayerHomeData is not a player specific thing
tardy delta
you probably want to go for player specific home data
so you would end up with a Map<UUID, PlayerHomeData>, assuming PlayerHomeData has a Map<String, Home> or smth internally. PS an UUID is just an identifier to get a player from
cuz now all the homes are stuffed together ig and there no way to distinguate between players
is dintinguate even a word idk
uh well why having homedata twice
