wraith rapids
also what's this
an enchant plugin
is it shit?
i need a not shit enchant plugin
wraith rapids
you should make it not shit so I can use it
waxen plinth
RedLib makes enchantments easy to make
wraith rapids
i'm sure it does
waxen plinth
I think gecko's plugin uses it
sage swift
I can't even copy the text on github mobile
waxen plinth
lol
wraith rapids
by checking every item in every slot 20 times a tick
wraith rapids
and cloning them 5 times for each check
wraith rapids
and then comparing them to a string in a .txt file
waxen plinth
I actually focus pretty heavily on performance
opal juniper
lmao
waxen plinth
r/onejoke but for redlib
waxen plinth
paper viper
suslib
clever sequoia
guys
waxen plinth
Cinnamon roll time
wraith rapids
anyway, i find just listening to the relevant events to be sufficient for maintaining which enchants are active on a player
waxen plinth
Goodbye
wraith rapids
like yeah, I do check each slot every few seconds
clever sequoia
how can i take it out the <> when i chat on my server
waxen plinth
And that's fine
wraith rapids
it doesn't really matter that much if a player has some enchant active for 2 seconds after somehow being stripped of items by a third party plugin
waxen plinth
Checking it every tick is really not that heavy though
wraith rapids
it's still 20 times heavier than checking it every second
waxen plinth
Much more expensive things than that happen every tick
wraith rapids
depends on what you're comparing it to
sage swift
chunk loading B)
wraith rapids
for example... are you comparing it to a craftitemstack or a bukkit itemstack
wraith rapids
ItemStack is the superclass that Craftstack extends
Craftstack is a wrapper of the nms stack
the implementation of each differs
comparing a bukkitstack with a craftstack causes 4 itemmeta clones
whilst comparing a craftstack with another craftstack causes none
sage swift
yeah what if one is a 1.15 item and the other is a 1.16 item
waxen plinth
Lol
lilac dagger
ItemStack is the superclass that Craftstack extends
item stack extends nothing, i think you mean the itemmeta?
itemstack is a concrete class
sage swift
craftitemstack extends itemstack
wraith rapids
bukkit itemstack is the superclass that craftstack extends
CraftItemStack wraps NMSStack and extends ItemStack
it's a strange design choice that is in place to let you instantiate new ItemStack even though it is an API class and should contain no implementation
opal juniper
GUYS, Lets calm it down
can i get some help tho
i have no clue how to send a packet with this:
PacketContainer sandPacket = this.protocolManager.createPacket(SPAWN_ENTITY);
sandPacket.getIntegers().
write(0, 500).
write(1, (int) EntityType.FALLING_BLOCK.getTypeId()).
write(2, (event.getLocation().getBlockX())).
write(3, (event.getLocation().getBlockY())).
write(4, (event.getLocation().getBlockZ()));
sandPacket.getDataWatcherModifier().write(0,sandWatcher)
``` but it doesn't work, i dont know how to spawn a falling block entityI tried looking at this as well but it didn't help:
https://minidigger.github.io/MiniMappingViewer/#/spigot/server/1.16.4/PacketPlayOutSpawnEntity
opal juniper
I'll get banned before i calm down
lmao
wraith rapids
my point is that a seemingly trivial check operation can become very expensive if the itemmeta is very large and you have to clone it 2 times just so that you can compare it to another item
lilac dagger
wait you're right
wraith rapids
I had to hunt down a ton of superfluous itemmeta cloning when I unfucked slimefun cargo networks
shit was cloning like 3 gigabytes of itemmeta clones onto the heap every time it ran
sage swift
lilac dagger
shit was cloning like 3 gigabytes of itemmeta clones onto the heap every time it...
jeez
wraith rapids
call me traumatized but I know that comparing itemstacks can be explosively expensive in the worst case scenario
waxen plinth
shit was cloning like 3 gigabytes of itemmeta clones onto the heap every time it...
Oh yeah doesn't getItemMeta internally create a clone of the item tag every time it's called rather than caching
wraith rapids
myes
waxen plinth
🙃
lilac dagger
it can get pretty bad but i think there's a bit of optimization going in i bet
waxen plinth
Love that
wraith rapids
and isSimilar calls it twice
wraith rapids
once for getDurability and a second time for comparing the meta
waxen plinth
Wow
lilac dagger
Oh yeah doesn't `getItemMeta` internally create a clone of the item tag every ti...
why is this a thing?
wraith rapids
because bukkit is shit
waxen plinth
Hmm
wraith rapids
it's literally a 1 line fix but nobody does it
waxen plinth
I have my own method for comparing items
I can make it cache the ItemMeta for different trait comparisons
lilac dagger
sure you want to prevent wrong user input but the item meta is safe from altering or is it not?
wraith rapids
unless it uses the underlying nms stack and you are not involving bukkit stacks in the operation, you will still be cloning itemmeta for each check
waxen plinth
It lets you choose which traits to compare, i.e. name, lore, amount
wraith rapids
the issue is that just looking at those is going to have that shulker box full of max size books cloned for every check
even if you cache it, you have to clone it again the next tick when you look at the slot again
waxen plinth
Yeah I get that much
wraith rapids
which can still be relatively expensive
which is why i'd rather have it 20 times less expensive
at the cost of some enchants very rarely lingering for an extra second
wraith rapids
you don't know that
rotund pond
Hello !
I will have a few questions for static methods ...
Why are they bad?
In which case can I use them? In which case not?
thank you for your time
waxen plinth
I do know that
wraith rapids
what if I want to enchant my shulker box
waxen plinth
??
waxen plinth
Oh that
wraith rapids
not the armor
waxen plinth
I mean, I've used it on a server with 100+ concurrent players and it never caused issues
There were other things that caused issues which I then optimized
wraith rapids
i'm sure those 100+ concurrent players weren't concurrently holding shulker boxes with max size books in them
waxen plinth
Unless it starts even showing up in timings I think it's fine
Hm
I'm pretty sure it won't compare that directly through bukkit
Can't say for sure
But I'm pretty sure BlockStateMeta is similar to ItemMeta in that it creates the BlockState when you request it rather than storing it internally
wraith rapids
thing is that the entire meta gets cloned when you access any part of it
checking the name of a shulker box will convert all of those books from nms NBTTagCompound to bukkit itemmeta
lilac dagger
that's on immutability programing
wraith rapids
it's either all or nothing
lilac dagger
is there a
wraith rapids
i'm working on a live-view itemmeta impl for myself but working with nms is cancer so it's on hold
lilac dagger
ItemStack#isSimilar(ItemMeta)?
wraith rapids
there isn't, and even if there was, it'd still clone the meta of the other itemstack
lilac dagger
no
wraith rapids
twice
wraith rapids
yes, it'd still clone the itemmeta of the itemstack you're calling it on
wraith rapids
that'd clone the itemmeta twice for both of them
wraith rapids
the isSimilar impl of ItemStack calls getItemMeta twice
it is however overridden by CraftItemStack which compares the underlying NMS ItemStack if the other itemstack is a CraftItemStack too
lilac dagger
you should push a fix on git for md5 to notice
wraith rapids
so comparing two craftstacks is significantly cheaper than comparing a craftstack and a bukkitstack
or a bukkitstack and another bukkitstack
lilac dagger
still even if it's fixed, the old versions will still have the problem
wraith rapids
old versions can suck my dick
wispy fossil
words to live by
lilac dagger
I have always fought the bukkit api's myself whenever I coded my plugins
wraith rapids
bukkit is pretty good in comparison to quite a few things but it does have its own share of problems
there are some areas where it's next to unusable
like world generation and the new data-driven stuff like loottables from datapacks
lilac dagger
there would be an easy fix to this problem
wraith rapids
biggest issue with bukkit is that it refuses to go forward and refuses to drop backwards compat
lilac dagger
a private, read only way of checking the meta data
wraith rapids
yeah, it would be super easy to fix this one
lilac dagger
where there is no immutability involved
wraith rapids
i have no clue why it is the way it is still
nobody seems to care about it
but like redempt said it really isn't a big issue for most servers with most plugins
so i guess nobody cares
lilac dagger
it might have been skipped due to the excesive comments
wraith rapids
for my slimefun fork i wrote a new itemstack implementation that's expressly designed to be used for repeated issimilar comparisons
it caches equals relations and shit
and caches both bukkit meta and nms meta and compares whatever is present to avoid cloning shit whenever possible
i'll eventually hook the live-view itemmeta impl to it and it'll be pretty nice
i'll call it HitlerItemStack
and release it as a lib on splögget
and watch it get taken down in .4 microseconds
lilac dagger
what's your fascination with hitler? 🥶

Entity class has a private static final AtomicInteger that represents the next eid
you'll need to reflect into it unless there is an api way of getting its value
there is also a nms way of creating an entity without spawning it in a world physically, which would probably be the simplest way

there is no more

If I wanted something that'd allow zombies to spawn with red leather gear for 8 minutes and then after 8 minutes it were to stop after 8 minutes, what code would I need for that?
opal juniper
I still dk if i have managed to spawn a block
wraith rapids
@quaint mantle what kind of an answer are you expecting
wraith rapids
there are two ways
either you have a start timestamp
and then in your listener or whatever you compare the current time to that timestamp
and if it's over 8 minutes, abort
the other way is to use the bukkit scheduler to run a task that aborts your thing after 8 minutes
quaint mantle
how would i do the second option
wraith rapids
Bukkit.getScheduler().runTaskLater(plugin, () -> {
//code to make your thing stop
}, delay);
plugin is an instance of your main class
upper vale
Why does e.getPlayer().getInventory().getItemInMainHand().getType() return AIR on PlayerDropItem :bruh:
wraith rapids
delay is the number of ticks to delay the execution by
get the dropped item from the event
quaint mantle
so "delay" is in ticks?
upper vale
I want to check if the dropped item was from their main hand though
wraith rapids
delay is in ticks yes
quaint mantle
ty
wraith rapids
i have no clue which one of those it is
probably the one from protocollib
the one in WrappedDataWatcher
quaint mantle
so would i make the red armour chance outside of it and then after that many ticks i put the code inside saying to not make a red armour chance and it stops it?
wraith rapids
uh i guess
quaint mantle
ah okay thank you
wraith rapids
you make the code in that block stop the code that's spawning them
as for how you do that depends on how you're spawning them
flip a boolean or something
opal juniper
this is what i have, does shit all tho
@EventHandler
public void oncrouch(PlayerToggleSneakEvent event){
Player player = event.getPlayer();

PacketContainer fallingBlock = protocolManager.createPacket(SPAWN_ENTITY);
fallingBlock.getIntegers().
write(0,fb.getEntityId()).
write(1, 26).
write(2, 70);
fallingBlock.getDoubles().
write(0, player.getLocation().getX()).
write(1, player.getLocation().getY() + 5).
write(2, player.getLocation().getZ());
PacketContainer meta = this.protocolManager.createPacket(PacketType.Play.Server.ENTITY_METADATA);
meta.getIntegers().write(0, fb.getEntityId());
WrappedDataWatcher watcher = new WrappedDataWatcher();
WrappedDataWatcher.Serializer serializer = WrappedDataWatcher.Registry.get(Byte.class);
watcher.setEntity(player);
watcher.setObject(0, serializer, (byte) (0x40));

try {
this.protocolManager.sendServerPacket(player, fallingBlock);
this.protocolManager.sendServerPacket(player, meta);
} catch (final InvocationTargetException e) {
e.printStackTrace();
}
}
ik that i haven't set the correct meta objects
im just gonna use some nms shite for meta for now:
net.minecraft.server.v1_16_R3.Entity nmsEntity = (net.minecraft.server.v1_16_R3.Entity) fb;
final PacketPlayOutEntityMetadata metaPacket = new PacketPlayOutEntityMetadata(nmsEntity.getId(), nmsEntity.getDataWatcher(), true);

then something on line 3 is null and you're calling a method on it

wraith rapids
you can't make it not null

anyone know why im getting a null pointer?
wraith rapids
null means there is nothing
lyric grove
wraith rapids
the only way to make nothing not nothing is put something in it
but since you have nothing you can't put anything in it
the only thing you can do is abort
the player is not holding an item
the held item is null
absent
empty
devoid of value
check whether e.getItem() is null and if it is, return before calling any methods on it

in this class
otherwise there is no way for you to get the YamlConfiguration out of this object

oh i thought the folder would be created automatically
I created plugins/<name> and it's fixed
So do you have any idea why the file doesn't occur automatically?
eternal oxide
if your original yml file is in your jar you can simply use saveResource to get it out
if its the default config use saveDefaultConfig(). It will create the folder and save the config.yml from the jar into the folder
wraith rapids
createFile doesn't create the directory, that's just how it works
you'll need to use mkdir or mkdirs to create the directory first, if it doesn't exist

can some tell me agein why arraylist can be bad in some case?
i believe 7smile7 told me about it but i can't find message
ivory sleet
appending on the list at the end may be O(n) complexity and contains is also O(n)
get and set by index is O(1) for ArrayList
LinkedList has O(1) for appending elements to it iirc
But ArrayList is arguably the best list data structure for arbitrary stuff
It generally has faster iteration time than both LinkedList and CopyOnWriteArrayList
But also should be worth mentioning ArrayList uses System::arraycopy for resizing its array making the add operation quite fast
Edit time complexity is generally something we consider when our data structures become bigger
round finch
appending on the list at the end may be O(n) complexity and contains is also O(n...
Thanks alot! i were looking for that infomation!
did you look on wiki?
pls send me source link
round finch
what about hashmap?
winged mica
if you need a list to load and have fast shearchs you usar one tipe
if you need a list too keep changing it all the time, other times are better
round finch
just looking at time complexity
winged mica
yep, but doing what?
ivory sleet
what about hashmap?
contains O(1) put O(1) remove O(1), iterate O(n)
round finch
just trying to learn more

But remember time complexity just tells u the worst amount of operations sort of
winged mica
contains O(1) put O(1) remove O(1), iterate O(n)
that is it
ivory sleet
For instance IdentityHashMap is better (faster) than HashMap although they have the exact same time complexity
sullen marlin
uh
winged mica
sometimes it is better if we doo some testing with several strutures, to find out what is more suitable
ivory sleet
Yeah
sullen marlin
IdentityHashMap is just a normal HashMap that uses Object.equals/hashcode rather than the subclass ones
winged mica
i still use hashtables
ivory sleet
No it uses System::identityHashCode

but now days there are improved strutures over that

guys I want to seperate something from my main and I created a new class for register the events to main but I cant use public void shulker(InventoryClickEvent e)
this is the code https://paste.md-5.net/iwitozasig.java
winged mica
did you register that class for the events on your main?
hollow canopy
yes
winged mica
implements Listener missing
round finch
how do i set the time to the very start of night in a world called "10"
getWorld("10").setTime(Number Long)
hollow canopy
method inside constructor 🤔
I am new at java
round finch
World world10 = Bukkit.getWorld("10");
hollow canopy
method inside constructor 🤔
can you give an example how can I fix it?
quaint mantle
getWorld("10").setTime(Number **Long**)
ty
round finch
World10.setTime( );
hollow canopy
@winged mica thanks thats worked
round finch
if you wanna use that
hollow canopy
method inside constructor 🤔
but now how can I Fix this
winged mica
public class ShulkerCanta { should be public class ShulkerCanta implements Listener {
first start
hollow canopy
yes I did it that way
round finch
wait is Class Mob constructor use for Custom mobs?
maybe.. oh
winged mica
not having this, i think you event register shouldn't be working
winged mica
yes I did it that way
k
PluginManager.registerEvents(new ShulkerCanta(), this);
on your main?
winged mica
show us
hybrid spoke
but now how can I Fix this
just put it outside
hollow canopy
But if I put it outside how can I register the event
upper vale
Is there a packet for the item held aniamtion?
hybrid spoke
But if I put it outside how can I register the event
its still registered then
as long as you keep it marked with @EventHandler
and let your class implement Listener
and register the class in your onEnable
hollow canopy
getServer().getPluginManager().registerEvents(new ShulkerCanta(), this);
like this?
my other class name is ShulkerCanta
okey I got it
winged mica
and on https://paste.md-5.net/iwitozasig.java take out the constructer
you puted the event inside of the construcor
try this
public class ShulkerCanta {
@EventHandler
public void shulker(InventoryClickEvent e) {
if(e.getClick().equals(ClickType.LEFT)) {
if(e.getCurrentItem() != null && e.getCurrentItem().hasItemMeta()) {
ItemStack box = e.getCurrentItem();
if(box.getItemMeta() instanceof BlockStateMeta) {
BlockStateMeta blockmeta = (BlockStateMeta) box;
if(blockmeta.getBlockState() instanceof ShulkerBox) {
ShulkerBox shulker = (ShulkerBox) blockmeta.getBlockState();
Inventory inv = Bukkit.createInventory(null, 27);
inv.setContents(shulker.getInventory().getContents());
e.getWhoClicked().openInventory(inv);
}
}
}
}

@maiden thicket like this?
maiden thicket
<@!409492766129913867> like this?
i meant isnt null haha but yeah
and uh
add a logger in there like
Bukkit.getLogger().info("dispatched cmd");
sage swift
aaaaaa why is your variable capitalized
maiden thicket
aaaaaa why is your variable capitalized
🥲
fierce salmon
tbh idk
maiden thicket
when u use command.getName() to check the command being called and not separate classes
🥲🥲🥲🤚🏽
sage swift
also pretty sure there is player.dispatchCommand or whatever
just search command in the methods

AsyncPlayerChatEvent::setFormat
outer sorrel
I have a custom event thats being called asynchronously but I cant cancel it, all the other code in the event works fine
@EventHandler
public void flagEvent(FlagEvent event){
event.getPlayer().sendMessage("e"); // works
event.setCancelled(true); //doesnt work
}
and this is it being called, its called from an async thing
FlagEvent flagEvent = new FlagEvent(player);
Bukkit.getPluginManager().callEvent(flagEvent);
if(flagEvent.isCancelled()) {
return;
}
thats calling it sync?
outer sorrel
well it doesnt cacel then still
ivory sleet
send the method maybe?
outer sorrel
i guess here
public void fail(Player player) {
FlagEvent flagEvent = new FlagEvent(player);
Bukkit.getScheduler().runTask(FlappyAnticheat.getInstance(), () -> Bukkit.getPluginManager().callEvent(flagEvent));
if(flagEvent.isCancelled()) {
return;
}
and its called here
@Override
public void onPacketPlayReceive(PacketPlayReceiveEvent e) {
//bunch of code here
fail(player);
}
public void fail(Player player) {
FlagEvent flagEvent = new FlagEvent(player);
Bukkit.getScheduler().runTask(FlappyAnticheat.getInstance(), () -> Bukkit.getPluginManager().callEvent(flagEvent));
if(flagEvent.isCancelled()) {
return;
}
still not entire method
outer sorrel
the only code after that is sending messages
ivory sleet
so cancelling ur event will just avoid sending messages?
outer sorrel
basically
outer sorrel
ok, how would I get it be canceled?
maiden thicket
implements cancellable
if event not cancelled then call event
ivory sleet
send FlagEvent class
outer sorrel
public class FlagEvent extends Event implements Cancellable {
private final Player player;
private boolean isCancelled;
public FlagEvent(Player player) {
this.player = player;
this.isCancelled = false;
}
@Override
public boolean isCancelled() {
return this.isCancelled;
}
@Override
public void setCancelled(boolean isCancelled) {
this.isCancelled = isCancelled;
}
private static final HandlerList HANDLERS = new HandlerList();
@Override
public HandlerList getHandlers() {
return HANDLERS;
}
public static HandlerList getHandlerList() {
return HANDLERS;
}
public Player getPlayer() {
return this.player;
}
}
youre returning the task lol
outer sorrel
i didnt change anything for this calss
upper vale
thats not going to cancel sending the messages
you need to send the messages within the task in order for the return to do anything
ivory sleet
TheDoominator that packet receiving is async right
upper vale
additionally async events should have super(true)
outer sorrel
thats not going to cancel sending the messages
so i should do
if(!flagEvent.isCancelled()) {
//code
}
otherwise you'll get error
outer sorrel
TheDoominator that packet receiving is async right
yes
upper vale
additionally async events should have `super(true)`
also do super(true) in the event constructor or you cant call it async
outer sorrel
ill add the super thing now
upper vale
Yeah the super isnt really relevant rn since you're calling the even sync atm
ivory sleet
have smtng like this then:
public void fail(Player player) {
FlagEvent flagEvent = new FlagEvent(player);
Bukkit.getScheduler().runTask(FlappyAnticheat.getInstance(), () -> {
Bukkit.getPluginManager().callEvent(flagEvent));
if(flagEvent.isCancelled()) {
return;
}
Bukkit.getScheduler().runTaskAsynchronously(FlappyAnticheat.getInstance(), () -> {
//handle event async
};
}
but yeah idk depends on what u exactly want
outer sorrel
Yeah the super isnt really relevant rn since you're calling the even sync atm
the super thing worked
upper vale
^
outer sorrel
thanks
upper vale
if youre just sending messages, i dont really see a benefit of that being async
ivory sleet
that too
outer sorrel
the packet plugin i use makes it async
ivory sleet
why not continue event flow async?
ivory sleet
i guess here
```java
public void fail(Player player) {
FlagEvent flagEve...
this is calling the event sync
ok
nice
have a good day

how do i make a music disc play with a radius of 1000 blocks in a certain world
sage swift
you uh
dont
sounds have a radius
but the problem with sounds is that once they start in a location, they will continue to play there
so even if you play a music disc for all online players at their locations, once they move or teleport far enough away they won't hear it
quaint mantle
Yeah
Well my world has a border of 100
and a build limit of 128 blocks
getWorld("10").playSound( Sound.MUSIC_DISC_WARD, 3);
ive figured this out but
it requires a location and i don't know how to save the co ords 0, 0, 0 in a location
sage swift
use the Location constructor
quaint mantle
whats the location constructor

hey what is the generally used entity to make floating text? like on a server lobby which would have a mob nametag as text without a mob (well, invisible)
hollow river
oh okay ^^ thank you!
sage swift
armor stands were usually the way to do it, recently the meta has become area of effect clouds
upper vale
weird question but uh
is it possible for a PlayerInteractEvent to not be cancelled properly if the server is lagging
hollow river
does the mob matter for performance reasons?
also im seeing only the nametag of the top level passenger mob, is there any way i can show nametags on all passengers? (trying to make a healthbar + name above a mob)

im getting this error but I dont use the eventdamagebyblockevent
[22:01:43 ERROR]: Could not pass event EntityDamageByBlockEvent to Tutorial v1.0
here is the code it has an issue with:

LivingEntity entity = (LivingEntity) event.getEntity();
if (entity.getName().equals("DefiantBurger")) {
if (entity.getHealth() - event.getFinalDamage() < 1) {

entity.sendMessage("§c§l(!) §cYou almost died!");

}
here is the error below it:
java.lang.ClassCastException: org.bukkit.craftbukkit.v1_16_R3.entity.CraftItem cannot be cast to org.bukkit.entity.LivingEntity
but im not casting an item to a living entity as far as I know
fierce salmon
i want to set the itemstack amount to 3 how would i do that?
sullen marlin
you're literally casting it on the first line of the method
you need an instanceof check
& look at the parameters available for new ItemStack
sage swift
EntityDamageByBlockEvent is a subclass of EntityDamageEvent as well
and yeah when an item is destroyed EntityDamageEvent is called
you need to check that the entity is a living entity before you cast it
sage swift
since an item is not, it errors

im guessing this is either some weird ass plugin calling the event with "left click air" out of nowhere or a server lag or ping thing?
cant possibly think of what could be wrong inside my plugin lol
It seems that spinning in circles while looking at just blocks is fine, spinning in circles while looking at just air is fine, but if you start moving your mouse really fast over blocks and air the event just comes out of nowhere

It seems that spinning in circles while looking at just blocks is fine, spinning...
after further debugging, the event ALWAYS fire give or take 60 millisecons after the previous interact event, and the click type is always LEFT_CLICK_AIR

is it only with a hoe? does it happen with only a plugin to broadcast interact events?
hollow river
Im kinda having the issue of having to make everything 100% futureproof and "perfect" as i can, it kinda prevents me from just making things and i lose motivation because i spend days or weeks on a single small thing
Does anyone have tips or the same issue and what's the best solution? I've managed to make things now but it'll probably happen again where i'd lose motivation because of it
sage swift
i've lost the drive to make anything at all before, where i just sit for days thinking about the project but not actually doing anything
i think it's totally normal, just comes and goes
and i think with practice it has gotten easier to know exactly what is required to make everything as needed
and yknow bugs do happen thats just a part of development
hollow river
Yeah its really annoying, i tried to minimize and focus on not doing that with my current project and so far i've been able to actually make things work, quest system, mob spawning, custom mobs, dialogue etc
Well its not bugs, but more of things like "i wonder how a plugin the scale of hypixel would do this" and well that's where it goes downhill and i get stuck trying to make it "professional" even though it works just fine
solemn shoal
dont futureproof
just make it work
i subconciously branch off my classes
(in this example JavaSource and JenkinsSource both extend Source so i can cast without issues)
solemn shoal
yeah like, idk how i do it
i need something? ill make a class for it
then like, 10 minutes later ill be like "tf am i doing lmao, oh well might aswell finish it"
hollow river
Yeah writing too much code is a curse
hollow river
I just need to get on with it, make it happen and move on to the next thing
solemn shoal
https://gitlab.com/TheArcaneBrony/essentialtools/-/tree/master/src/net/thearcanebrony/essentialtools
take a look at the classes in there
it really is a curse but it works well
like, all of the events i use are separate classes
following a ~set structure
hollow river
I still have this issue with quests, and dialogues where i want full customization (like idk, when you kill 3 zombies your sword gets dropped, then an xp orb comes flying at you idk, just any customization) which j do by creating a class for every quest i make, so im not loading quests in but end up having a cluttered package with quest classes
solemn shoal
ah yeah
thats fun
maybe you should have an enum or something with goal types
idk
lambdas and callbacks lol
sage swift
at some point i wonder, "which part of this has to be hardcoded, and which part can be in a config?"
hollow river
I'll copy the link and take a nice look tomorrow since im in bed rn and trying to read that on phone is eh
solemn shoal
eh it was just an example of my class structure
hollow river
Yeah i was thinking of initializing the quests with like quest1.class or using an enum etc, but that's for later
Ohh alright
solemn shoal
im not saying its good, but it well, just works
hollow river
Well it looked good from what i've seen
hollow river
My code has structure but looks messy because i make the quests and mobs, dialogues too in separate classes (all extending from a parent of course though)
solemn shoal
well having differnt quest classes is fine
as long as all the data related to them is stored within
hollow river
Meh just stuff the big blocks into separate methods and call them like registerEvents(); that's what im doing
solemn shoal
fair
hollow river
Has to be done at some point, so might as well make it look nice since you cant avoid it
solemn shoal
ignore the mess that is that onCommand at the bottom
moving those into classes is still on my todo list 😅
solemn shoal
i think its a huge rats nest
the main class is probably the best class in the entire project
hollow river
Yeah same here
hollow river
Im constantly switching ways of doing things in my head like sending a class reference or just making a new instance already, stuff like that
Well one question i actually have
hollow river
So i just made it so that i can create spawn points for mobs, where every x seconds it'd act like a spawner
hollow river
But idk if i should add a new async repeated schedule thing for every "mob spawner" or if i should have one timer which just calls every "mob spawner"
solemn shoal
hm
good question
i'd say look into how vanilla does it
wait
youre saying async
hmmm
hollow river
I also want some spawners to spawn only every 60 seconds, some 10 seconds etc but i might have a solution for that
Yeah yeah
hollow river
So ending up with 70+++ might be a bad idea in the long run
solemn shoal
you'd have to ask around because i think thats a matter of opinion
and implementation
ah yeah @untold kernel
ofcourse
this is my main hub for plugin dev questions lol
solemn shoal
i used to

One time I was so brain effed that I was performing 5 database things on main thread
cinder thistle
there are so many things wrong with this screenshot
untold kernel
On playerjoinevent
hollow river
Yeah so i think i'll have an async repeated task which runs every 5 seconds which will be the min amount for a spawner to activate, and then maybe i can add a counter for each spawner which only gets triggered at every 20 seconds (every 4 calls if the async takes 5 seconds)
solemn shoal
checking the balance itself is fine, i do that multiple times per tick for every player
well
you'd need it to be a multiple of 5 seconds then
solemn shoal
there are so many things wrong with this screenshot
shut up i know lmao
hollow river
Yeah i think 5 is a good number
cinder thistle
specifically I'd like to point out that you're using what looks like a util class to get core things
