ember estuary
how can i extend a class to add my own features, and then make an instance of that class into an instance of my own class?
(cant change that superclass)
i just get a ClassCastException
when trying to cast it to my subclass
its possible with a wrapper class, but then i'd need to re-make every method and direct them to the method on the super object
That's my try using a wrapper class
public class Canvas {
CraftMapCanvas craftMapCanvas;
public Canvas(CraftMapCanvas craftMapCanvas) {
this.craftMapCanvas = craftMapCanvas;
}
public void drawRect(int x, int y, int width, int height, byte color) {
for(int i = x; i < x + (width-1); i++) {
for (int j = y; j < y + (height-1); j++) {
craftMapCanvas.setPixel(x, y, color);
}
}
}
public void drawText(int x, int y, MapFont font, String text) {
craftMapCanvas.drawText(x, y, font, text);
}
// ^ Would need to do this for all other methods, which is a lot of work
}
Or you can just expose the super object and call methods on it directly
ember estuary
how
young knoll
Except the ones you want to change
ember estuary
how can i do that
ember estuary
oh
i see
no way to connect myPlayerWrapperInstace.sendMessage() directly to the internal Player Instance?
young knoll
You could
But if you don’t need to change anything, don’t bother
Otherwise you’ll just have a ton of 1 line methods calling this.wrappedPlayer.XYZ
ember estuary
making it exposed is just kinda un-intuitive to use imo
but if thats the only solution
ember estuary
well yeah, but i meant connecting it automatically
without redoing all methods
xD
young knoll
You might be able to do it with your IDE
ember estuary
i use IntelliJ
young knoll
Eclipse has an option to overwrite/inherit methods
I’m sure IntelliJ does too, somewhere
ember estuary
alright xD
I can't use extends to achieve my goal, can i?
extends would allow me to easily add some methods and stuff. but then theres the problem that bukkit gives me an instance of the extended class / superclass, so i cant downcast it. or can i somehow?

Hello
I need help to find the version someone is joining my server with
such as: "Fabric 1.17.1"
or whatever their client says
I already have an on join event setup
I just can't find anything to do after that

If you really want to do it yourself you need to read the incoming packets
The version I believe is just part of normal connection packets
Forge fires a specific packet you can use to detect it
Not sure if fabric does
ember estuary
i wanna have a drawPolygon function which you can pass vertices: public void drawPolygon(int x1, int y1, int x2, int y2, (int, int)... rest).
Is there a way to have optional parameters (so you can pass infinitely many vertices), but always force two (x and y) at once?
So when using that function you can either call drawPolygon(x1, y1, x2, y2) , or drawPolygon(x1, y1, x2, y2, x3, y3), but not drawPolygon(x1, y1, x2, y2, x3)
(I know i could use a Pair<Integer, Integer> or SimpleEntry<Integer, Integer>, but i dont really like having to make objects for simply passing numbers)
young knoll
You can overload the method with all the different options
ember estuary
what does that mean
u mean create
drawPolygon(int x1, int y1, int x2, int y2)
drawPolygon(int x1, int y1, int x2, int y2, int x3, int y3)
drawPolygon(int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4)
etc ?
young knoll
Yes
ember estuary
but then i cant have infinitely many
ember estuary
alright :/
or just throw an error if args.length%2 == 1
xD
but thats at runtime sadly
young knoll
You could also do that
ember estuary
or is it
quaint mantle
can do varargs and do the length check
young knoll
Yes it’s runtime
ember estuary
does the compiler know/warn its gonna throw an error?
young knoll
No
quaint mantle
just dont do user error 🙂
ember estuary
programmers are the users in my case
so then usererror is alright, right?
its an api
young knoll
Spigot has a lot of stuff like that
For example, if you try to use .distance between 2 locations in different worlds you will get a runtime exception
ember estuary
ok, so i tried using Pairs, and i get the following warning: Possible heap pollution from parameterized vararg type
What does it mean?
Googling didnt really make it any clearer
Set<Pair<Integer, Integer>> getPolygonPoints(Pair<Integer, Integer> ... vertices) { ... }
young knoll
ember estuary
well idk if its save
how can i fix it
i saw that post before, but didnt really help me fix the problem
is it unfixable?
just add @SafeVarargs and hope for the best?
ember estuary
and that will fix it?

I was wondering, with NMS, if you are trying to develop against mojang mappings, how can i check, for ex, what the name of the class EntityInsentient, is in the mojang mappings?
https://nms.screamingsandals.org/ <-- this is a pretty good website, however it only shows your the remapped things and not the original spigot mappings, so if I try to search EntityInsentient, nothing shows up
sullen marlin
You can view all mappings in the bt work folder
Or just figure it out based in context
jade perch
context is my preferred way
sweet pike
context is my preferred way
ye usually thats how i would do it
but it took me more than 30 mins to find that EntityInsentient was just Mob LOL
- using context is ridiculously hard when you are dealing with this such as pathfinders
packets are understandable
quaint mantle
woulda took a couple seconds if you just started from an actual mob and went down the chain
jade perch
ctrl+click from intellij is op
sweet pike
nah nah thats not the problem
Cuz basically what happened was i needed a private field of type EntityInsentient but obv needed that in mojang mappings
sweet pike
ctrl+click from intellij is op
i dont see how that would've been useful, would've had nothing to off on anyway
jade perch
That's how I made my simulator so it should be fine for anything else

when I was converting I just setup a 2nd project with spigot mappings

go down the extend chain
sweet pike
go down the extend chain
extend off what tho? If i knew EntityInsentient was talking abt a mob, i easily would've gone to the zombie class or smt and see what it inherited
Here i had no clue what EntityInsentient actually was, therefore didn't know what it was linked to
quaint mantle
just go off the same mob
like cow
you'll see the different class names if you do the 2 project setup very quickly
sweet pike
you'll see the different class names if you do the 2 project setup very quickly
yeah thats what I did in the end
Like for ex, now with pathfinders I have a completely different issue, trying to find what the mojang mapping equivalent of EntityLiving.h(EntityInsentient) and the h() name is from a yt vid like 2 years ago so method names prolly changed as well
but I get what you mean and stuff
Just really wished that https://nms.screamingsandals.org/ would let you search for spigot names as well

How do you get click events for this panel?
It doesnt print anything not even null or -999 like when you click on the outside of the inv (InventoryClickEvent)

How do you get click events for this panel?
take a look at this, might be what you're looking for
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Merchant.html
noble lantern
You see i did see that class
However, i wanted to use this class:
However the click events only give Merchent inventories when villager GUI's get clicked...
my bad i meant clicked
smoky oak
wait where comes click event from again?
noble lantern
wait where comes click event from again?
Essentially InventoryClickEvent doesnt give a MerchantInventory
If i could get a MerchantInventory, it has a selected recipe method
However i feel MerchantInventory would be something you would need to make yourself?
And then you would have to handle esentially the whole trading system yourself?
smoky oak
aren't you already casting that to MerchantInventory? Why is that an issue then?
noble lantern
Because Merchant != MerchantInventory
the most bottom broadcast doesnt get fired
smoky oak
well of course
were both stupid
you cast the inventory to a merchant inventory
but you check if its a merchant inventory before you do
smoky oak
does it give an error when removing that if line?

It basically just keeps printing "You are getting cold!"?

but sends many messages in a second
yep
and increasing very fast the cold value
smoky oak
@noble lantern https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/InventoryView.html#getTitle()
check if its the correct inventory then return if it isnt. InventoryView should be part of the event
and with what you were doing earlier, event.getInventory() there should be no errors
acoustic pendant
do you know how to solve it burchard?
smoky oak
wait
event.getClickedInventory()
i think event.getInventory() returns player inventory
oops

Its the way your calling the runnable
Your probably creating a bunch of those runnables
acoustic pendant
oh
makes sense
@noble lantern if (playerHeigh.containsKey(player)) {
if (player.getLocation().getY() >= 50)
}
maybe like that should be done?
@Override
public void run() {
for (Player player : Bukkit.getOnlinePlayers()){
if (!playerHeigh.containsKey(player)) {
if (player.getLocation().getY() >= 50){
playerHeigh.put(player.getUniqueId(), player);
}
}```like that
noble lantern
<@!545365141668102175> if (playerHeigh.containsKey(player)) {...
im talking about outside of the runnable
Or your creating more runnables inside the runnable
If it continuinly gets faster, that means more runnables keep getting registered
acoustic pendant
yes, i understand that
noble lantern
However if its the same rate, then its just the rate of the runnable
So you need to find where you calling the method that registers that runnable
acoustic pendant
```java
@Override
public void run() {
fo...
but here, i'm using a hashmap
to place the user
and if the user is not in the hashmap it just create one
@EventHandler
public void coldAndHeatSetter(PlayerMoveEvent e) {
^^
noble lantern
your calling a runnable in that?!?!?!
supple parcel
Am I missing something?
public void onBlockPhysics(BlockPhysicsEvent event) {
Block b = event.getBlock();
if (b.getType() == Material.REDSTONE_TORCH || event.getSourceBlock().getType() == Material.REDSTONE_TORCH ||
event.getChangedType() == Material.REDSTONE_TORCH) {
Bukkit.broadcastMessage("Cancelled redstone torch!");
event.setCancelled(true);
}
}```
Only if I cancel air (Where all 3 block/materials are air) will this physics update be cancelled.do not even use that event lmao xD
Just call the runnable once in onEnable
and check player positions every x ticks
acoustic pendant
i just realized
noble lantern
PlayerMoveEvent calls so many times, and when you have lots of players it becomes pretty rough
and it would explain stuff getting faster
acoustic pendant

Uhm yes

It's basically an extract of code in a larger plugin

Ive never done block physics like that before
However maybe you need to cancel physics directly on the Block?

burchard, now it works, but keep sending the message instead of just 1 time

How exactly does that work..
You can see I'm cancelling it everytime there's a redstone torch involved in the physics

sec
acoustic pendant
Unless your Key is an `Object`?
is the player
noble lantern
is the player
So your key is a Player, however your puting a UUID as the key?
So,
you should be checking
acoustic pendant
Map<UUID, Player> playerHeigh = new HashMap<>();```for the UUID, not the Player
Because your just directly checking the Player object
Not the Player's UUID
if (!playerHeigh.containsKey(player.getUniqueId())) {}
oh
noble lantern
However, what is the purpose of this HashMap?
noble lantern
IMO it seems kind of redundant if you just want to see if player are above 50
Instead keep a list of UUID's
HashMap of UUID, Player will use up more memory in the long run
List of UUID's though is very lightweight and serves the same purpose
and you can just get Player from Bukkit#getPlayer(UUID)
noble lantern
i'm silly, the move event and now the uuid object
Wait dont go Bukkit.getPlayer(UUID)
Bukkit.getOnlinePlayers()
If you do the List way, use Bukkit.getOnlinePlayers() and then check UUID
quaint mantle
hi, weird question, anyone know how i can make the water not flow outside the worldborder but also still flow normally inside? whenever i check if its outside and cancel the event it does that since the closest path for it to flow is only outside the border https://gyazo.com/7f508bf92004c858c8e57091f4a6eee0

Don't have a solution, but a suggestion would be to try re-call physics?
Another could be to set the blocks outside the border to barrier before it even tries to flow.

Well it's not returning a Merchant it's returning an inventory with the merchant type i.e. Merchant Inventory

Okay so

If you do the List way, use Bukkit.getOnlinePlayers() and then check UUID
what? in the for loop i'm using Bukkit.getOnlinePlayers()
noble lantern
When i logged getInventory it logged the same thing
and the class name made it seem really weird and not like it was MerchantInventory because it was InventoryMerchant by NMS
noble lantern
what? in the for loop i'm using Bukkit.getOnlinePlayers()
Ignore anything i said about getPlayer()
Just use List of UUID and then loop through it using getPlayer(UUID)
getOfflinePlayer(String) was the method i was getting confused with so ignore me for that sorry

and the class name made it seem really weird and not like it was MerchantInvento...
Since you appear to be using Paper API I suggest you try paperweight. This way you can access NMS and other classes and see what they do
noble lantern
Never heard of PaperWeight tbf
chrome beacon
In this case you could check and see that the CraftInventoryMerchant is the implementation of the Merchant inventory interface
noble lantern
In what cases for clicking inventory would inventory even be Merchant anyways?
Would the Merchant inventory be what the Villager is holding? Like when they pickup food?

I'm actually not sure
This is why having access to NMS can be useful you can check how things work

basically to have more control over the mining speed

Sounds like assloads of NMS ngl

yeah few packets
i listen for player dig and play block break animations
not that bad tho
the worst will be armorstand animations
all packets
for performance reasons
noble lantern
Ngl though you can have a pretty popular plugin if you take one of those features and make it standalong
If you made a standalone for making the block breaking status staying after mining people would love that
cause iirc only a mod can do that
misty current
yea but in that case i would have to try to replicate vanilla mining
i don't think i can get somehow else what stage was a block in when a player stopped mining

// Optionals can be used like this.
// The method ".orElse(Block)" returns the value if present or

}
public static void refillWater(final Player player) {
final Block startBlock = getNearestWater(player);
if (startBlock == null) {
return;
}
// This is not how you get the Block a Player is looking at. You should ray trace instead.
// final Block to = player.getEyeLocation().add(player.getLocation().getDirection().normalize()).getBlock();
// Like this:
final RayTraceResult rayTraceResult = player.rayTraceBlocks(3.0);
if (rayTraceResult == null || rayTraceResult.getHitBlock() == null) {

}
final Block to = rayTraceResult.getHitBlock();

If a Blocks state us updated then a packet is sent to the client. If the client does not have this Block then he will create it.
I think for some Blocks a physics update is triggered and thus corresponding data is sent to the clients nearby so the client
re-creates the Blocks based on those packets.

Yes but if the client receives an update packet for this Block afterwards then the client will simply re-create the Block based on the received data.

Hmm. what can I do to prevent that

This is whats probably happening
- Send delete packet
- Block gets updated (redstone, or lightning, or state change)
- Client becomes update packet and realises that there is no Block
- Client re-creates the Block and applies the update

Hmm. what can I do to prevent that
Per-Player Block states are a bit tricky. You should probably build a whole state handler abstraction for that. It involves listening to outgoing packets and fetching those which could affect a clients perception of changed Blocks.

Is it possible that chunk's PDC are broken in 1.18-rc3?
Everything I save into a chunk's PDC is gone after a server restart
@Override
public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args) {
Player player = (Player) sender;
Chunk chunk = player.getLocation().getChunk();
if(args[0].equals("get")) {
for(NamespacedKey key : chunk.getPersistentDataContainer().getKeys()) {
System.out.println(key.getNamespace()+":"+key.getKey());
}
}
if(args[0].equals("set")) {
chunk.getPersistentDataContainer().set(new NamespacedKey(this,"test"),PersistentDataType.STRING,"someValue");
}
return true;
}
using /test set, then /test get, it shows "test:test", but after a restart, nothing

String online = String.valueOf(getServer().getOnlinePlayers());
e.setMaxPlayers(Integer.parseInt(online))
why?
tender shard
because getOnlinePlayers() returns a Collection and not an integer
tender shard
use size() on the player collection
fast onyx
okay ty

you can't just add filters inside <project>

tardy delta
is there even a way to change the player's name above his head without using packets?
scoreboards hmmm

oh shit, I was right, it's indeed a bug: https://hub.spigotmc.org/jira/projects/SPIGOT/issues/SPIGOT-6814?filter=allopenissues

i'm using https://www.spigotmc.org/threads/user-friendly-material-type-to-in-game-item-name-enum.82425/ for an /item command, does anyone know how i can check if the enum contains args[0] i tried if(ItemNamesEnum.valueOf(args[0]) == null ) { but it says Condition 'ItemNamesEnum.valueOf(args[0]) == null' is always 'false'
quaint mantle
i'm using https://www.spigotmc.org/threads/user-friendly-material-type-to-in-gam...
Because valueOf is never null, if there's no value for given string, it will throw an exception
ItemNamesEnum.VALUE.toString().contains(args[0])
peak granite
VALUE?
quaint mantle
whatever value your enum has that you want to compare
tender shard
It is safe to extend location? I wanna make an unmodifiable wrapper around
at least it's not forbidden in the docs
peak granite
whatever value your enum has that you want to compare
i don't understand
my command is /item <item name> i'm comparing arg0 to see if it matches an enum
tacit drift
how can i make it so it shows the breaking block animation on a certain block? without someone actually breaking that block
quaint mantle
i don't understand
in your case you would loop through the enum and compare each value rather than only one
