Which Guava has builtin

quaint mantle Sep 22, 2021, 9:16 PM

#

I figured it out lol thanks

#

Omg its boss man

opal juniper Sep 22, 2021, 9:25 PM

damm that’s a shame

#

i really wanted some money

#

i don’t really see the issue with it if they consented to it

#

but eh nvm

quaint mantle Sep 22, 2021, 9:30 PM

I highly doubt anyone would actually enable a cryptominer

What about a plugin that just makes every block pink concrete

unkempt peak Sep 22, 2021, 9:37 PM

#

Wow hi md5

#

That's the first time I've seen you in the help channel

#

Lol ig he's just never on when I am

gaunt saffron Sep 22, 2021, 9:44 PM

#

what's the easiest way:
i would like to check if no-one joined the server is last hour (like the server is empty for 1h)

unkempt peak Sep 22, 2021, 9:45 PM

#

just store the time of the last leave/join and then every 10 minutes or whatever check if that time is over an hour

#

actually you can just store it if that leave drops the player count to 0

#

so if the last player leaves store the time they left

ivory sleet Sep 22, 2021, 9:46 PM

#

It probably needs to be mapped anyways

#

Maybe a Cache<Integer,E> where Integer serves as the index?

#

if you use caffeine it’s possible to add a remove listener

eternal night Sep 22, 2021, 9:47 PM

#

or just reuse this as a set and use the lists hashcode as the key

#

then you have your "collection"

ivory sleet Sep 22, 2021, 9:48 PM

#

ivory sleet if you use caffeine it’s possible to add a remove listener

Which then removes the element from a list or smtng

gaunt saffron Sep 22, 2021, 9:48 PM

#

unkempt peak actually you can just store it if that leave drops the player count to 0

will try, i suck in java tho...

unkempt peak Sep 22, 2021, 9:48 PM

#

Ok if you need more help dm me

ivory sleet Sep 22, 2021, 9:48 PM

#

The list implementation could be a LinkedList as I assume you might want add to be O(1)

I'm surprised I've never come into this before, but can you force a block update?

quaint mantle Sep 22, 2021, 10:35 PM

#

young knoll I'm surprised I've never come into this before, but can you force a block update...

Block#update() ?

#

BlockState#update()*

#

and uh

#

im kind of noob, im not sure what im doing

#

if you cant tell, im trying to make a minutely rewards system...

#

im definitely not doing it right

young knoll Sep 22, 2021, 10:37 PM

#

quaint mantle BlockState#update()*

Tried that, doesn't seem to work

paper geyser Sep 22, 2021, 10:47 PM

#

quaint mantle im kind of noob, im not sure what im doing

theres 20 ticks in a second

#

so

#

and 300 seconds in 5 minutes

#

why not just make a runnable that runs every 5 minutes

quaint mantle Sep 22, 2021, 10:48 PM

#

because thats not gonna work?

#

if someoen joins halfway through 5 minutes that runnable is gonna give them shards next time it runs

#

not next 5 minutes

paper geyser Sep 22, 2021, 10:48 PM

#

your system is doing the same thing tho isn't it?

#

oh wait

quaint mantle Sep 22, 2021, 10:49 PM

#

not at all???

paper geyser Sep 22, 2021, 10:49 PM

quaint mantle Sep 22, 2021, 10:49 PM

#

gg

#

ya

vivid lion Sep 22, 2021, 10:50 PM

#

why not do it for 5 mins loop and when a player joins in they get assigned a separate non-repeating task before being put it into the 5 min loop

paper geyser Sep 22, 2021, 10:50 PM

#

ooh

#

yeah that

vivid lion Sep 22, 2021, 10:51 PM

#

so save the 5 minute loop into an object and the list of players attached to it

paper geyser Sep 22, 2021, 10:51 PM

#

when they join create a runnable and when they leave stop it

#

save their time too

#

obviously

Hi, I would need some help, in fact, I made a custom event, and for some reason it doesn't seem that it cancel it when I do e.setCancelled(true) (the event implements cancellable of course)

#

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

#

here is the custom event

vivid lion Sep 22, 2021, 11:14 PM

#

how did you link it back to the section you used the event

#

did you remember to also call the event

#

register listeners

opal sluice Sep 22, 2021, 11:14 PM

#

yup

#

the event works

vivid lion Sep 22, 2021, 11:15 PM

#

so everything works now right

opal sluice Sep 22, 2021, 11:15 PM

#

public class VehicleInputListener implements Listener
{
    public VehicleInputListener() {}
    
    @EventHandler
    public void onVehicleInput(VehicleInputEvent e)
    {
        e.setCancelled(true);
        System.out.println("HI ! " + e.getInput().name() + " " + e.isCancelled());
        System.out.println("Nice ! " + e.getPlayer().getName() + "\n" + e.getVehicle().toString());
    
        e.dismount();
    }
}

vivid lion Sep 22, 2021, 11:15 PM

#

what about the part where you called it

opal sluice Sep 22, 2021, 11:15 PM

#

the e.isCancelled() inside the sysout does return true

#

but

#

                    if(move != null)
                    {
                        final VehicleInputEvent vie = new VehicleInputEvent(event.getPlayer(), move);
                        Bukkit.getScheduler().runTask(plugin, () -> Bukkit.getPluginManager().callEvent(vie));
                        System.out.println(vie.isCancelled());
                        event.setCancelled(vie.isCancelled());
                    }

#

it returns false

#

I don't get why

quaint mantle Sep 22, 2021, 11:16 PM

#

why are you running a task

#

Bukkit.getPluginManager().callEvent(vie)

opal sluice Sep 22, 2021, 11:16 PM

#

To make it sync

quaint mantle Sep 22, 2021, 11:16 PM

#

k

opal sluice Sep 22, 2021, 11:16 PM

#

cause events needs to be called sync

quaint mantle Sep 22, 2021, 11:17 PM

#

my guess is that you're calling it async then sysout before its called

vivid lion Sep 22, 2021, 11:17 PM

#

i assume this is a bukkit event

#

you called this from

opal sluice Sep 22, 2021, 11:17 PM

#

Oooh, yeah, it's an async event it's called from

#

that's maybe bc of that

vivid lion Sep 22, 2021, 11:17 PM

#

what event is it

#

asyncplayerchatevent?

quaint mantle Sep 22, 2021, 11:18 PM

#

its his own

opal sluice Sep 22, 2021, 11:18 PM

#

PacketEvent

vivid lion Sep 22, 2021, 11:18 PM

#

i see

opal sluice Sep 22, 2021, 11:18 PM

#

PacketEvent is async I guess

opal sluice Sep 22, 2021, 11:20 PM

#

quaint mantle my guess is that you're calling it async then sysout before its called

So, the async task goes "faster" than the synced one and it sysout before having it called. Well, just need to make it sync then x)

quaint mantle Sep 22, 2021, 11:21 PM

#

its simple

opal sluice Sep 22, 2021, 11:21 PM

#

yup done

quaint mantle Sep 22, 2021, 11:27 PM

#

opal sluice What are you trying to do ?

give people shards every 5 minutes after they're online

vivid lion Sep 22, 2021, 11:28 PM

#

ye as i was saying you can put them on a separate non repeating task

#

when they first join

opal sluice Sep 22, 2021, 11:28 PM

#

make a list of player with the actual play time, at the 5 min mark give them

#

you can do it with an unique scheduler

quaint mantle Sep 22, 2021, 11:28 PM

#

opal sluice make a list of player with the actual play time, at the 5 min mark give them

so thats sort of what im doing i think?

#

im really not sure

opal sluice Sep 22, 2021, 11:28 PM

#

nope

quaint mantle Sep 22, 2021, 11:28 PM

#

shardsloop is just HashMap<Player, Long>

opal sluice Sep 22, 2021, 11:29 PM

#

You're making a scheduler per player aren't you ?

quaint mantle Sep 22, 2021, 11:29 PM

#

opal sluice You're making a scheduler per player aren't you ?

i'll use UUID, thats not too big of a big problem

ohhh

#

okay

as for the time check.. is that mostly right?

#

alright

opal sluice Sep 22, 2021, 11:32 PM

#

quaint mantle its what im trying to not do

5000 isn't 5 seconds in a bukkit runnable

#

100L is

quaint mantle Sep 22, 2021, 11:33 PM

#

opal sluice 5000 isn't 5 seconds in a bukkit runnable

oh jesus

#

what why

opal sluice Sep 22, 2021, 11:33 PM

#

cause it works on ticks

quaint mantle Sep 22, 2021, 11:33 PM

#

okay

#

oh eah that makes sense

#

i saw "Long" and thought.. TIMESTAMP

opal sluice Sep 22, 2021, 11:33 PM

#

Would be too precise for the actual server to run

quaint mantle Sep 22, 2021, 11:33 PM

#

yeah, makes sense

#

so 100L is 5 seconds?

opal sluice Sep 22, 2021, 11:34 PM

#

yup as 20 is 1

quaint mantle Sep 22, 2021, 11:34 PM

#

meaning 6000L should be 5 minutes?

opal sluice Sep 22, 2021, 11:34 PM

#

yes

quaint mantle Sep 22, 2021, 11:34 PM

#

okay coollllll

vivid lion Sep 22, 2021, 11:37 PM

#

a 5 minute loop would suffice as long as you have a player join separate non repeating task at the start which then puts them back on the 5 minute loop

opal sluice Sep 22, 2021, 11:39 PM

#

quaint mantle 👍🏿

Ok, now the sync is ok, but the async event isn't cancelled 🤡

quaint mantle Sep 22, 2021, 11:40 PM

#

i dont understand

opal sluice Sep 22, 2021, 11:41 PM

#

I mean, when I do cancel the event, it seem that it already happened async and so it doesn't seem to be cancelled when cancelled by the sync task

#

Like, if the PacketEvent would be cancelled, the player wouldn't be able to jump for example

quaint mantle Sep 22, 2021, 11:41 PM

#

are you sure it would be 6000 @opal sluice

opal sluice Sep 22, 2021, 11:41 PM

#

if I cancel it directly inside the async task, it does cancel it properly

quaint mantle Sep 22, 2021, 11:41 PM

#

oh yeah nvm

opal sluice Sep 22, 2021, 11:41 PM

#

20*300 = 6000

opal sluice Sep 22, 2021, 11:42 PM

#

opal sluice if I cancel it directly inside the async task, it does cancel it properly

but if I cancel it inside a sync task, it does not cancel it, or it does cancel it but after that the event happened (the player has already jump)

AtomicInteger from java or MutableInt from apache.

As you dont need multithreading you should go with MutableInt

torn oyster `Condition 'Bukkit.getOfflinePlayer(args[0]) != null' is always 'true' `

getOfflinePlayer will always return an OfflinePlayer.
It will first check for an online player
then check in the offline player cache
then check all profiles on the disk
if there is no data available it will query the mojang API and create a new profile.

So it will return an OfflinePlayer no matter what.
This method can be quite expensive if the player is not online and not in the player cache (about the last 10.000 players which connected)

Well, look at how Mojang does it. That's just how it is with NMS.

They're creating a Goal for this (which in this case is a Zombie), telling it to Attack turtles (Turtle.class), at a random interval of 10, it must see the Turtle but doesn't have to "reach" it (true, false), and the Turtle must be on land. (Turtle.BABY_ON_LAND_SELECTOR is the predicate for "this turtle must be a baby AND on land for the zombie to attack it.) You'd use the Predicate part to filter the player.

And what does DoubleChest#getLocation give you?

prisma needle Sep 23, 2021, 3:59 PM

it gives me the location directly in between both sides

ivory sleet Sep 23, 2021, 3:59 PM

#

Oh ok

prisma needle Sep 23, 2021, 4:00 PM

#

so idk mby there is a more manual way of just checking if it's connected to a chest, then checking for direction, and then getting the block shifted by 1

proud basin Sep 23, 2021, 4:00 PM

would you count a DoubleChest as a BlockState?

Yeah sounds like a doable workaround since the api seems to behave somewhat oddly

prisma needle Sep 23, 2021, 4:01 PM

#

Ok now the question is, how do I check which direction half a double chest is facing :P

proud basin Sep 23, 2021, 4:01 PM

#

nvm

prisma needle Sep 23, 2021, 4:02 PM

yeah I have, which is why I figured the rightSide and leftSide should give different locations... but alas

Another question:

On some occasions I cancel a block break event. However when breaking a double chest half of it looks detached from the other side after the event is canceled until I interact with it again. Is there some solution to this?

hasty prawn Sep 23, 2021, 4:12 PM

How are you breaking it

how should i fix this?? (there are two symbols that mustn't be here :|

ivory sleet Sep 23, 2021, 4:18 PM

one way is to use ChatColor.COLOR instead of §COLOR

Anyone who can spoon feed me?

can someone help me with it?

be patient, one message suffices

sharp kelp Sep 23, 2021, 4:26 PM

Okay sorry

I have to sleep unfortunately but may check any replies

sharp kelp Sep 23, 2021, 4:28 PM

#

ivory sleet be patient, one message suffices

I will just ask and sorry for ping but is asking for spoon feeding allowed here? I got taunted in another plugin development help discord in which because I am not a pro and not even at a level of noob so I didn't got what they meant and when I asked can you edit the code and give me which will help me understand what you meant then they said we wont spoonfeed
So I will ask first

ivory sleet Sep 23, 2021, 4:31 PM

#

it is allowed but a naive way to solve your problem

sharp kelp Sep 23, 2021, 4:31 PM

#

Yes It annoys the helpers a little

#

I actually want to learn java only for bukkit api

ivory sleet Sep 23, 2021, 4:32 PM

#

it will just solve your issue superficially which is the long term problem (spoonfeeding)

sharp kelp Sep 23, 2021, 4:32 PM

#

so I am starting java along with bukkit api and I came acrosss some other professional devs which did same

ivory sleet Sep 23, 2021, 4:32 PM

#

yeah

sharp kelp Sep 23, 2021, 4:32 PM

#

so If I directly ask for code

#

Is it rude and spoon feed?

ivory sleet Sep 23, 2021, 4:33 PM

#

its not rude but spoonfeed, people will less likely help you

sharp kelp Sep 23, 2021, 4:33 PM

#

because I thought it makes it easier for both

#

soo okay

#

in another server I asked for help but the person was just saying Initialize Initialize and i didnt get it

ivory sleet Sep 23, 2021, 4:34 PM

it doesnt

sharp kelp Sep 23, 2021, 4:34 PM

#

Okay thankz

slim kernel Sep 23, 2021, 4:34 PM

I think theres a big difference between spoon feed where you want to get the exact code you need and asking for an example because you can understand the code easier then

sharp kelp Sep 23, 2021, 4:34 PM

Yea well I guess spoonfeed is that they fill up the spoon and put in your mouth

proud basin Sep 23, 2021, 4:35 PM

#

What don't you understand about initializing

ivory sleet Sep 23, 2021, 4:35 PM

Because if u spoonfeed youll learn scarcely anything, and then you'll come back the next day asking for more, its a continues evil circle

trail flume Sep 23, 2021, 4:35 PM

Hiya. When looping through player.getInventory().getContents() ItemStack is null, do you know why?

sharp kelp Sep 23, 2021, 4:35 PM

While Non spoon feed would be they teach us how to fill up a spoon and put it in our mouths oursellves

sharp kelp Sep 23, 2021, 4:35 PM

oh actually

trail flume Sep 23, 2021, 4:41 PM

I'm looping through the contents

It's an ItemStack[]

proud basin Sep 23, 2021, 4:42 PM

let me try something

sharp kelp as I guessit will be less annoying

Ill be able to help in 50min or so

sharp kelp Sep 23, 2021, 4:43 PM

#

proud basin let me try something

Jtx sorry for ping but in the code he gave if the inventory has no items then value = null right?

proud basin Sep 23, 2021, 4:43 PM

#

yeah I'd put the ItemStacks in a list

trail flume Sep 23, 2021, 4:44 PM

#

but then it wouldn't even loop

sharp kelp Sep 23, 2021, 4:44 PM

#

so if we add a else statement saying if its null and then run its specific action wont that work?

trail flume Sep 23, 2021, 4:44 PM

#

there would be nothing to loop

#

and my inv isnt empty

sharp kelp Sep 23, 2021, 4:44 PM

#

Oh Hmm I guess I will leave it to pros

proud basin Sep 23, 2021, 4:44 PM

#

so ItemStack[] inventoryItems = p.getInventory().getContents()

sharp kelp Sep 23, 2021, 4:44 PM

#

trail flume and my inv isnt empty

Maybe its not detecting it?

trail flume Sep 23, 2021, 4:45 PM

#

proud basin so ``ItemStack[] inventoryItems = p.getInventory().getContents()``

But why does it even need that, it's just unnecessarily storing a variable

proud basin Sep 23, 2021, 4:45 PM

#

then you can do for (ItemStack itemStack : inventoryItems) {

sharp kelp Sep 23, 2021, 4:45 PM

#

Oh I guess you are making this in a util form

trail flume Sep 23, 2021, 4:45 PM

#

yes

trail flume Sep 23, 2021, 4:45 PM

#

proud basin then you can do ```for (ItemStack itemStack : inventoryItems) {```

that's pretty much what I'm doing

balmy coyote Hi, any ideas what can be used in order to remove Elytra from End Item Frames? L...

You either modify the world generator,or listen to chunk generation and check for it,it is afterall a entity so it can be easier to get

sharp kelp Sep 23, 2021, 4:59 PM

#

balmy coyote And Elytra it's the last one to go

I think if you add it that if the event detects the item in the player inventory it will auto remove it

balmy coyote Sep 23, 2021, 4:59 PM

#

So upon generation obtain all entities in that chunk if instanceof ItemFrame and contains Elytra remove?

sharp kelp Sep 23, 2021, 4:59 PM

#

Hmm

onyx shale Sep 23, 2021, 4:59 PM

#

yep

sharp kelp Sep 23, 2021, 4:59 PM

#

Maybe a event to check any items frames with that item

onyx shale Sep 23, 2021, 4:59 PM

#

considering the chunk itself has a getEntities inside it

sharp kelp Sep 23, 2021, 4:59 PM

#

And then get the location of it and break it then use kill item to kill the item in a radius of 2 or 1

balmy coyote Sep 23, 2021, 5:00 PM

#

I'll try that out just now and see if it gives any results

onyx shale Sep 23, 2021, 5:00 PM

#

best bet for the generation one

#

if you listen to all item frames you risk deleting ones placed by the player

balmy coyote Sep 23, 2021, 5:00 PM

#

Yeah i know

sharp kelp Sep 23, 2021, 5:00 PM

#

Yea but dont you wanna disable the item itself?

balmy coyote Sep 23, 2021, 5:00 PM

#

No

sharp kelp Sep 23, 2021, 5:01 PM

Oh then I guess my idea is wrong in that case 🙂

unless block positions are cached, I don't think != would work.

eternal oxide Sep 23, 2021, 6:23 PM

#

from and to are not block positions, they are Locations, so bad to use them to test, which is why it uses getBlockX etc

tardy delta Sep 23, 2021, 6:36 PM

#

lavish hemlock you mean `!event.from().equals(event.to())`?

hmm yea

worldly ingot Sep 23, 2021, 6:48 PM

#

Yeah. getFrom() and getTo() are Location instances which aren't rounded. The slightest movement would allow the condition to pass

tardy delta Sep 23, 2021, 6:49 PM

#

true

worldly ingot Sep 23, 2021, 6:49 PM

#

Though that method above only cares to call once a whole block position was changed

#

Could call getFrom().getBlock().equals(getTo().getBlock()) but that's then creating an unnecessary CraftBlock middle-man instance just to perform the same comparison

#

So yeah, compare getBlockXYZ()

hasty prawn Sep 23, 2021, 7:19 PM

The best way to do it probably would be for the user to get their own API key and give that to your plugin to use.

shadow tide Sep 23, 2021, 7:19 PM

config.yml is accessed by everyone.

hasty prawn Sep 23, 2021, 7:19 PM

They need to pay for it then ¯_(ツ)_/¯

shadow night Sep 23, 2021, 7:19 PM

¯\_(ツ)_/¯

#

Or, you could use something like a password hash for the api key

#

So no one could access it

eternal oxide Sep 23, 2021, 7:21 PM

Can't be done

If the key is in your jar it can be read

you could create a own api to access the api key on a secured way idfk

I just though, who the fuck would decompile a plugin to get access to an api key

No, just don't tell them about the key

No one would do it then

then obfuscate the plugin, add a lot of artifacts. Add fake api keys. Etc.

eternal oxide Sep 23, 2021, 7:24 PM

Safer, but still not safe. at some point the key gets used. It can be read from memory

Ok so this is what I got. From what I can tell it's not actually checking the PlayerJoinEvent or it would've sent a message in console

         this.getServer().getPluginManager().registerEvents(this, this);

                 Player player = event.getPlayer();
                 
                 
                 double x = 0.50;
                 double y = 65;
                 double z = 0.50;
          
                 Location spawn = new Location(event.getPlayer().getWorld(), x, y, z);

             }
         }, 20L);

Entities (including players) are Attributable https://hub.spigotmc.org/javadocs/spigot/org/bukkit/attribute/Attributable.html

spice hornet Sep 23, 2021, 7:45 PM

#

Is this some reflection action or how does it work?

worldly ingot Sep 23, 2021, 7:45 PM

#

Yes, reflection

#

When registered it filters through methods in the class, checks if it's annotated and gets the first argument in the method. Registers it to the appropriate HandlerList and calls them reflectively

young knoll Sep 23, 2021, 7:46 PM

#

Spigot gets all the methods annotated with @EventHandler and reflectively invokes them

spice hornet Sep 23, 2021, 7:46 PM

Ah yes, so basically checking using reflection what the signature is and what arguments it takes and based on that call the method? Why go with that complicated route?

Or is there some benefit from that that I don't see?

So SQLite?

spice hornet Sep 23, 2021, 7:55 PM

#

Try SQLite

quaint mantle Sep 23, 2021, 7:55 PM

Okay thanks

You have a couple options. Handle this with a BungeeCord plugin so you can communicate with it, or use something like Redis pub/sub (imo the better option)

I'm too lazy to use Redis, so i think I'll go for the bungeecord plugin

worldly ingot Sep 23, 2021, 8:00 PM

Redis can save your ass a lot in the future. It's a nice way to mimic packets

shadow tide Sep 23, 2021, 8:00 PM

#

In an attribute modifier their are 3 operations, ADD_NUMBER, ADD_SCALAR, and MULTIPLY_SCALAR. is there a way to subtract a number? I need to lower the player's max health by 1

worldly ingot Sep 23, 2021, 8:00 PM

#

ADD_SCALAR with a negative amount ;p

shadow tide Sep 23, 2021, 8:00 PM

#

k

worldly ingot Sep 23, 2021, 8:00 PM

#

Actually it might be ADD_NUMBER. I don't remember. One of them adds 1 I think by default

shadow tide Sep 23, 2021, 8:00 PM

#

U usually use ADD_NUMBER, idk what ADD_SCALAR does

winter sand Sep 23, 2021, 8:00 PM

#

worldly ingot Redis can save your ass a lot in the future. It's a nice way to mimic packets

And plugin channels aren't good enough?

worldly ingot Sep 23, 2021, 8:01 PM

#

Yeah, it's NUMBER

shadow tide Sep 23, 2021, 8:01 PM

#

what does ADD_SCALAR do?

worldly ingot Sep 23, 2021, 8:01 PM

#

Plugin channels work fine and are a viable options. Though it may suffer the same issues because plugin channels are player <--> server communciation

#

You still need a player

worldly ingot Sep 23, 2021, 8:02 PM

Looks like it's misnamed. MULTIPLY_BASE is more accurate

What do you put in the addModifier method?

shadow tide Sep 23, 2021, 8:14 PM

#

shadow tide What do you put in the `addModifier` method?

@worldly ingot

#

and, yes I looked at the docs

eternal oxide Sep 23, 2021, 8:17 PM

#

an AttributeModifier.Operation

#

.addAttributeModifier(Attribute.GENERIC_ATTACK_DAMAGE, new AttributeModifier("extra_damage", 10, AttributeModifier.Operation.ADD_NUMBER));```

#

an example

Hi, so I'm getting this warning (it doesn't affect my plugin) that says no such file or directory, when I create a file.

how do i check what the current weather is

You're probably trying to remove while iterating

#

Can you show the full code

#

You can use removeIf

#

Otherwise you could construct a second list of items to remove and then use removeAll

#

Removing from within an enhanced for loop also will not work

golden turret Sep 23, 2021, 9:36 PM

#

or you can remove while using iterator

how can i stop all them numbers from appring? [ Ping me ]

limber jackal Sep 23, 2021, 9:53 PM

@plain scroll round it when you are converting from float/double to string

plain scroll Sep 23, 2021, 9:54 PM

#

im adding it like this

#

nvm

#

i think i did it

#

anyone know why this wont lock the item in place? It works for all my other items in the gui

^^ fixed

young knoll Sep 23, 2021, 10:18 PM

So is there a good way to force a block update? setType doesn't update the block itself, only the blocks around it. Block.getState.update doesn't appear to work either

ivory sleet Sep 23, 2021, 10:19 PM

#

Isn’t there like a tick function?

young knoll Sep 23, 2021, 10:21 PM

#

Not sure?

#

Don't see anything on the javadocs

#

I'm surprised setBlockData doesn't cause an update

golden turret Sep 23, 2021, 11:14 PM

#

plain scroll how can i stop all them numbers from appring? [ Ping me ]

use formatters

young knoll Sep 23, 2021, 11:23 PM

#

String.format is probably the easiest

worldly ingot Sep 23, 2021, 11:26 PM

#

Or if you want to be really fancy, just cast it to an int lol

#

The truncation of that value is not at all significant

young knoll Sep 23, 2021, 11:26 PM

#

But what if I want some decimals

quaint mantle Sep 23, 2021, 11:26 PM

#

cast to float

worldly ingot Sep 23, 2021, 11:27 PM

#

In effect it's a whole number. 20 half hearts

#

Anything in between that should be considered insignificant for front-facing strings

#

Minecraft renders by truncating that value anyways

quaint mantle Sep 23, 2021, 11:28 PM

#

why does java return .000000000000000001 sometimes

young knoll Sep 23, 2021, 11:28 PM

#

Floating point precision errors

worldly ingot Sep 23, 2021, 11:30 PM

#

Pretty interesting topic tbh

#

Best example I can give. What's 1/3 + 1/3 + 1/3. It's 3/3, right? But how do you represent an infinitely repeating number using bits? You can't represent 0.33333333 forever, it has to stop somewhere. So if you add 0.33333333 + 0.33333333 + 0.33333333, you get 0.99999999

#

Boom, floating point precision

#

I think standard precision is 23 decimal places, though I could be off by like 1 or 2

young knoll Sep 23, 2021, 11:33 PM

#

And this is why you should always round your numbers if you are showing them to the user

quaint mantle Sep 23, 2021, 11:34 PM

#

intellij, fix

worldly ingot Sep 23, 2021, 11:35 PM

I've noticed Eclipse doing that recently too. Usually just an F5 fixes it

quaint mantle Sep 23, 2021, 11:35 PM

thanks

worldly ingot Sep 23, 2021, 11:36 PM

haha I dunno why it's doing that. Only started a few months ago

Yeah mine does it randomly too

torn oyster Sep 23, 2021, 11:45 PM

nvm did it
