Make different entities for different players | SpigotMC | Page 1

rigid torrent Oct 8, 2022, 6:00 PM

#

@tacit glade

#

so im gonna explain what I am doing just to clear up any confusion

#

the moment you first log on, you will spawn on a set of islands and on those islands there may be different mobs and stuff. I want the players to only share entities and stuff once they reach the end which is like a "home base"

#

its a little complicated

narrow hound Oct 8, 2022, 6:02 PM

#

So you want entities only visible to certain players?

rigid torrent Oct 8, 2022, 6:03 PM

#

i want my entities to almost be seperate for certain players

#

with their own pathfinding and health

#

they attack the player who is playing, and not a another player who happens to be also doing the beginning

tacit glade Oct 8, 2022, 6:04 PM

#

What version is this for so I can look for specific classes?

rigid torrent Oct 8, 2022, 6:04 PM

#

1.19.2

tacit glade Oct 8, 2022, 6:04 PM

#

kk ty

narrow hound Oct 8, 2022, 6:04 PM

#

I guess this is kind of impossible because you would need to create a fake entity and basically rewrite the code as similar to Minecraft’s one

#

I mean not really impossible

#

Just really hard

tacit glade Oct 8, 2022, 6:05 PM

#

narrow hound I guess this is kind of impossible because you would need to create a fake entit...

not really

#

Just figuring out the code for it right now

narrow hound Oct 8, 2022, 6:05 PM

#

It this is possible it would be really cool stuff

#

We should probably make a Library on this

rigid torrent Oct 8, 2022, 6:07 PM

#

I was thinking maybe hide the entites for one player sort of like how u can hide players from players and then assign each entity a different tag that tells them to only go for a certain player

tacit glade Oct 8, 2022, 6:09 PM

#

You may be able to do something like this @rigid torrent

#

        final Zombie zombie = new Zombie(EntityType.ZOMBIE, /* World goes here */);
        zombie.targetSelector.removeAllGoals();
        zombie.targetSelector.addGoal(0, new NearestAttackableTargetGoal<Player>(zombie, Player.class, true, (livingEntity) -> {
            if (!(livingEntity instanceof Player target)) {
                return false;
            }
            
            return target.getUUID().equals(/* Put the target players UUID in here*/);
        }));```

#

That's the code with mojang mappings

#

With spigot mappings it's this:

        EntityZombie zombie = new EntityZombie(EntityTypes.bj, /* World goes here */);
        zombie.bT.a();
        zombie.bT.a(0, new PathfinderGoalNearestAttackableTarget(zombie, EntityHuman.class, true, livingEntity -> {
            if (!(livingEntity instanceof EntityHuman)) {
                return false;
            }

            EntityHuman target = (EntityHuman)((Object)livingEntity);
            return target.co().equals(/* Put the target players UUID in here*/);
        }));```

rigid torrent Oct 8, 2022, 6:12 PM

#

So what does that do

tacit glade Oct 8, 2022, 6:12 PM

#

Basically

rigid torrent Oct 8, 2022, 6:12 PM

#

like brief explenation

tacit glade Oct 8, 2022, 6:12 PM

#

this allows the entity to ONLY attack the target player

rigid torrent Oct 8, 2022, 6:12 PM

#

Will it also pathfind to only the target player

tacit glade Oct 8, 2022, 6:12 PM

#

Which means you can then hide the entity from every other player

#

yea

#

it should do

rigid torrent Oct 8, 2022, 6:13 PM

#

How do u hide the entity

#

Is there a function for that in the Player?

tacit glade Oct 8, 2022, 6:14 PM

#

Mojang Mappings: ClientboundRemoveEntitiesPacket
Spigot Mappings: PacketPlayOutEntityDestroy

#

Like this -

rigid torrent Oct 8, 2022, 6:15 PM

#

I should probably ask how i would implement something like this

#

Ive never dealt with packets before

#

Do i call the above after a player joins?

tacit glade Oct 8, 2022, 6:16 PM

#

        ClientboundRemoveEntitiesPacket removeEntityPacket = new ClientboundRemoveEntitiesPacket(/* Put the entities id's that you want to hide here*/);
        for (final Player nonViewingPlayer : /* Provide the other players that aren't meant to see the enemy here */) {
            ((CraftPlayer) nonViewingPlayer).getHandle().connection.connection.send(removeEntityPacket);
        }```

#

That's for when the entities spawn in

rigid torrent Oct 8, 2022, 6:17 PM

#

how do i get an entities id?

tacit glade Oct 8, 2022, 6:17 PM

#

entity.getId()

#

Do you know if you're using mojang mappings or spigot mappings?

rigid torrent Oct 8, 2022, 6:17 PM

#

what do u mean by that

tacit glade Oct 8, 2022, 6:18 PM

#

Does either - ClientboundRemoveEntitiesPacket exist or PacketPlayOutEntityDestroy

#

If neither, then you have to run buildtools to get NMS code

rigid torrent Oct 8, 2022, 6:19 PM

#

when i type them in normally just into intellij nothing comes up to autocomplete

tacit glade Oct 8, 2022, 6:19 PM

#

Alright

#

https://www.spigotmc.org/wiki/buildtools/

BuildTools | SpigotMC - High Performance Minecraft

The home of Spigot a high performance, no lag customized CraftBukkit Minecraft server API, and BungeeCord, the cloud server proxy.

#

https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar

#

Download that, put it in a folder

rigid torrent Oct 8, 2022, 6:19 PM

#

does build tools work if im using paper

tacit glade Oct 8, 2022, 6:19 PM

#

Yeah it should still work

#

Because paper is built off of spigot

#

as long as paper hasn't changed anything major, then yeah

rigid torrent Oct 8, 2022, 6:24 PM

#

after i put it in a folder what do i do

tacit glade Oct 8, 2022, 6:24 PM

#

Open up command prompt

#

and enter this command -

rigid torrent Oct 8, 2022, 6:24 PM

#

should i just double click to run

tacit glade Oct 8, 2022, 6:24 PM

#

java -jar BuildTools.jar --rev 1.19.2 --remapped```

rigid torrent Oct 8, 2022, 6:25 PM

#

can i just double click

tacit glade Oct 8, 2022, 6:25 PM

#

no

rigid torrent Oct 8, 2022, 6:25 PM

#

ight

#

it finished

tacit glade Oct 8, 2022, 6:27 PM

#

It say build success?

rigid torrent Oct 8, 2022, 6:28 PM

#

oh wait

#

nvm

#

it said finished and then started decompiling everything

#

i see it all

tacit glade Oct 8, 2022, 6:29 PM

#

ah yeah

#

just wait for it to completely stop then

rigid torrent Oct 8, 2022, 6:31 PM

#

it idd

#

did*

tacit glade Oct 8, 2022, 6:31 PM

#

it says Build Success now?

rigid torrent Oct 8, 2022, 6:32 PM

#

not that but it said Everything completed successfully

tacit glade Oct 8, 2022, 6:32 PM

#

Okay cool

#

You using maven for your plugin?

rigid torrent Oct 8, 2022, 6:32 PM

#

#

should have probably put that in a paste

rigid torrent Oct 8, 2022, 6:32 PM

#

what file do i add it too

tacit glade Oct 8, 2022, 6:32 PM

#

but whatever

#

pom.xml

rigid torrent Oct 8, 2022, 6:33 PM

#

in order?

tacit glade Oct 8, 2022, 6:33 PM

#

just put the dependency inside of the dependencies section

#

and put the plugin inside of

    <plugins>
    
    </plugins>
</build>```

rigid torrent Oct 8, 2022, 6:34 PM

#

ok

#

it showed me a bunch of errors

tacit glade Oct 8, 2022, 6:34 PM

#

What is the error?

rigid torrent Oct 8, 2022, 6:34 PM

#

oh wait

#

put it in the wrong area

tacit glade Oct 8, 2022, 6:34 PM

#

ah

rigid torrent Oct 8, 2022, 6:34 PM

#

i have two errors

#

saying net.md-5:specialsource-maven-plugin:1.2.2 not found

tacit glade Oct 8, 2022, 6:36 PM

#

you clicked this then it appeared? if not, try click the button anyway

rigid torrent Oct 8, 2022, 6:37 PM

#

ight

#

i will respond in a bit gonna be away from my pc

tacit glade Oct 8, 2022, 6:38 PM

#

okay

rigid torrent Oct 8, 2022, 6:58 PM

#

u still here?

#

@tacit glade

tacit glade Oct 8, 2022, 7:00 PM

#

Yo

rigid torrent Oct 8, 2022, 7:00 PM

#

hey

#

still got the error

rigid torrent Oct 8, 2022, 7:00 PM

#

tacit glade you clicked this then it appeared? if not, try click the button anyway

i cant find this exact button

tacit glade Oct 8, 2022, 7:00 PM

#

rigid torrent saying net.md-5:specialsource-maven-plugin:1.2.2 not found

this?

rigid torrent Oct 8, 2022, 7:00 PM

#

yes

tacit glade Oct 8, 2022, 7:00 PM

#

try click this

rigid torrent Oct 8, 2022, 7:01 PM

#

tacit glade try click this

thats what i did

tacit glade Oct 8, 2022, 7:01 PM

#

oh?

#

weird

rigid torrent Oct 8, 2022, 7:01 PM

#

where did u want me to put the folder

#

for buildtools

tacit glade Oct 8, 2022, 7:01 PM

#

anywhere on your main drive (I think it has to be on main, not sure tho)

rigid torrent Oct 8, 2022, 7:01 PM

#

alright

#

its on my desktop

tacit glade Oct 8, 2022, 7:02 PM

#

Did you run the command exactly how I sent above?

#

when it was in that folder

rigid torrent Oct 8, 2022, 7:02 PM

#

yup

tacit glade Oct 8, 2022, 7:03 PM

#

rigid torrent yup

Well, that's weird then lol

rigid torrent Oct 8, 2022, 7:03 PM

#

                <version>1.2.2</version>```

#

thats the two lines causing the error

tacit glade Oct 8, 2022, 7:03 PM

#

Could you send your pom.xml in here?

#

?paste

#

https://paste.md-5.net

rigid torrent Oct 8, 2022, 7:04 PM

#

https://paste.md-5.net/alokomobus.xml

tacit glade Oct 8, 2022, 7:05 PM

#

try change the version to 1.2.4

tacit glade Oct 8, 2022, 7:05 PM

#

tacit glade you clicked this then it appeared? if not, try click the button anyway

and then click this -

rigid torrent Oct 8, 2022, 7:06 PM

#

it fixed the error

tacit glade Oct 8, 2022, 7:06 PM

#

Bet

#

No more errors in the pom?

rigid torrent Oct 8, 2022, 7:06 PM

#

nope!

tacit glade Oct 8, 2022, 7:06 PM

#

Awesome

Now we can continue with this

rigid torrent Oct 8, 2022, 7:07 PM

#

so test if what works again

tacit glade Oct 8, 2022, 7:08 PM

#

Check if "ClientboundRemoveEntitiesPacket" exists

rigid torrent Oct 8, 2022, 7:08 PM

#

found it

tacit glade Oct 8, 2022, 7:08 PM

#

pog

rigid torrent Oct 8, 2022, 7:08 PM

#

it does

rigid torrent Oct 8, 2022, 7:08 PM

#

tacit glade Check if "ClientboundRemoveEntitiesPacket" exists

this one specifically

tacit glade Oct 8, 2022, 7:08 PM

#

yep

rigid torrent Oct 8, 2022, 7:09 PM

#

i got it

#

i have an issue tho

#

not anything code based or anything

#

just that my test server isnt port forwarded and i have no idea how to test this

tacit glade Oct 8, 2022, 7:10 PM

#

You could probably turn it online-mode: false

#

and launch multiple clients

rigid torrent Oct 8, 2022, 7:10 PM

#

alright

#

but wouldnt that still kick me

tacit glade Oct 8, 2022, 7:10 PM

#

?

rigid torrent Oct 8, 2022, 7:10 PM

#

because like my normal client is still connected

#

its the same account twice on a server

tacit glade Oct 8, 2022, 7:11 PM

#

nah just launch up a cracked account

rigid torrent Oct 8, 2022, 7:11 PM

#

can i just use a forge build

#

i dont have a launcher for that

#

wait nvm

#

i can just ask a friend to help out with it

#

ill just put it on a minehut server or something

#

so where do I put the code blocks u sent

#

still struggling to understand trhat

tacit glade Oct 8, 2022, 7:13 PM

#

You're going to have to implement it yourself. I'm not going to really spoonfeed all the code. But, I will still help to tell you where to put it.

#

Basically

#

When a player joins, you may want to create the zombie

rigid torrent Oct 8, 2022, 7:13 PM

#

right

tacit glade Oct 8, 2022, 7:13 PM

#

tacit glade ```java final Zombie zombie = new Zombie(EntityType.ZOMBIE, /* World goe...

this one here

rigid torrent Oct 8, 2022, 7:13 PM

#

mhm

tacit glade Oct 8, 2022, 7:13 PM

#

And to actually place it in the world -

#

level.addFreshEntity(zombie, CreatureSpawnEvent.SpawnReason.CUSTOM);```

#

Now, that would make it show for every player, but this is just for testing for now

#

Making sure that the entity actually spawns in

#

Oh one sec

#

there, that's the method

rigid torrent Oct 8, 2022, 7:16 PM

#

which zombie do i import

tacit glade Oct 8, 2022, 7:16 PM

#

net.minecraft

rigid torrent Oct 8, 2022, 7:17 PM

#

same with EntityType?

tacit glade Oct 8, 2022, 7:17 PM

#

You may also want to set the zombies position by doing -

        zombie.setPos(new Vec3(x, y, z));```

#

Yep

rigid torrent Oct 8, 2022, 7:17 PM

#

tacit glade You may also want to set the zombies position by doing - ```java zombie....

ok

#

getting errors when trying to put the world in

tacit glade Oct 8, 2022, 7:20 PM

#


        final Level level = ((CraftWorld) world).getHandle();
        final Zombie zombie = new Zombie(EntityType.ZOMBIE, level);```

#

basically, what that does, is gets the world in NMS

rigid torrent Oct 8, 2022, 7:21 PM

#

alright

#

zombie.targetSelector.addGoal(0, new NearestAttackableTargetGoal<Player>(zombie, Player.class, true, (livingEntity) getting an error with <Player>

#

saying I should implement LivingEntity instead

#

now that mobs can attack eachother

tacit glade Oct 8, 2022, 7:22 PM

#


        zombie.targetSelector.addGoal(0, new NearestAttackableTargetGoal<>(zombie, net.minecraft.world.entity.player.Player.class, true, (livingEntity) -> {```

#

Since this is NMS code, it required NMS objects

#

instead of bukkit

#

bukkit is just an abstracted api on top of NMS

rigid torrent Oct 8, 2022, 7:23 PM

#

zombie.targetSelector.addGoal(0, new NearestAttackableTargetGoal<net.minecraft.world.entity.player.Player>(zombie, Player.class, true, (livingEntity) ->

#

this is what i have

tacit glade Oct 8, 2022, 7:24 PM

#

change the 2nd player to net.minecraft too

#

also, you don't need the one inside of the generics

tacit glade Oct 8, 2022, 7:24 PM

#

tacit glade ```java zombie.targetSelector.addGoal(0, new NearestAttackableTargetGoa...

so this will work

rigid torrent Oct 8, 2022, 7:24 PM

#

alright i did it

tacit glade Oct 8, 2022, 7:25 PM

#

Can you send a snippet of your code just to make sure everything is gucci

rigid torrent Oct 8, 2022, 7:25 PM

#

still getting errors so probably not gucci atm

#

Try that @rigid torrent

#

oh wait

#

1 sec

#

One suggestion to help your code be better for people to read or if you ever join the industry. @rigid torrent - don't use single letter variable names

rigid torrent Oct 8, 2022, 7:27 PM

#

oh i just like using p because its quick and i use it a lot

tacit glade Oct 8, 2022, 7:27 PM

#

yea

#

fairs

rigid torrent Oct 8, 2022, 7:28 PM

#

i know its not practical but its whatever

#

do u want me to try the code

#

or are u doing something

tacit glade Oct 8, 2022, 7:29 PM

#

Before you try the code. Make sure you do all this too -

tacit glade Oct 8, 2022, 7:29 PM

so just build and test right

not getting any zombie spawning in

nothign else in my plugin is working either

none of the commands anyway

Drag the -remapped jar from the folder in instead

rigid torrent Oct 8, 2022, 7:41 PM

#

drag it where

tacit glade Oct 8, 2022, 7:41 PM

#

In your server instead

rigid torrent Oct 8, 2022, 7:41 PM

#

just in the main server file

#

not plugins or anything

tacit glade Oct 8, 2022, 7:41 PM

#

in the plugins folder lol

#

just replace the current plugin with the -remapped.jar

rigid torrent Oct 8, 2022, 7:42 PM

#

tacit glade Drag the -remapped jar from the folder in instead

which jar would that be

#

i cant find it

#

is it in build tools?

tacit glade Oct 8, 2022, 7:42 PM

#

When you build the plugin, what is in the target folder?

rigid torrent Oct 8, 2022, 7:42 PM

the plugin

tacit glade Oct 8, 2022, 7:42 PM

anything else?

#

can you send an ss?

the other plugins i have

i cant put images here for some reason

the plugins folder

tacit glade Oct 8, 2022, 7:43 PM

#

oh

#

no

#

the "target" folder

#

of the plugin you built

#

there should be a "...-remapped.jar"

rigid torrent Oct 8, 2022, 7:44 PM

#

i build using an artifact

what should i build with?

tacit glade Oct 8, 2022, 7:45 PM

maven install

#

rigid torrent Oct 8, 2022, 7:46 PM

where will it build to

to a folder named "target"

rigid torrent Oct 8, 2022, 7:46 PM

#

in the project?

tacit glade Oct 8, 2022, 7:46 PM

#

yea

rigid torrent Oct 8, 2022, 7:46 PM

#

i see it

#

what jar

tacit glade Oct 8, 2022, 7:46 PM

#

tacit glade there should be a "...-remapped.jar"

.

rigid torrent Oct 8, 2022, 7:47 PM

#

yeah

tacit glade Oct 8, 2022, 7:47 PM

#

that one

rigid torrent Oct 8, 2022, 7:47 PM

#

drag it into plugins and delete old one?

tacit glade Oct 8, 2022, 7:47 PM

#

yeah

rigid torrent Oct 8, 2022, 7:48 PM

#

zombie spawned 😄

tacit glade Oct 8, 2022, 7:48 PM

#

pog

#

it attack you?

rigid torrent Oct 8, 2022, 7:48 PM

#

immidiantly

tacit glade Oct 8, 2022, 7:48 PM

#

Awesome!!

rigid torrent Oct 8, 2022, 7:48 PM

#

and everything else works

tacit glade Oct 8, 2022, 7:48 PM

#

: D

#

Now, that zombie, if I was correct with the code, should ONLY attack you

#

😄

rigid torrent Oct 8, 2022, 7:49 PM

#

yes

#

so now i need to hide the zombie right

tacit glade Oct 8, 2022, 7:50 PM

#

Yep

#

You can hide the zombie for everyone that doesn't need to see it

rigid torrent Oct 8, 2022, 7:51 PM

#

tacit glade ```java ClientboundRemoveEntitiesPacket removeEntityPacket = new Clientb...

this one?

tacit glade Oct 8, 2022, 7:51 PM

#

Yep 😄

rigid torrent Oct 8, 2022, 7:51 PM

#

so i put that in the join event aswell right

tacit glade Oct 8, 2022, 7:51 PM

#

yeah

rigid torrent Oct 8, 2022, 7:52 PM

#

i need to get the entities that i want to hide though

#

so when i spawn the entities in

#

can i give them a tag with the players uuid or something

#

and then any mob without it loses it

tacit glade Oct 8, 2022, 7:53 PM

#

rigid torrent and then any mob without it loses it

?

rigid torrent Oct 8, 2022, 7:53 PM

#

because i need to identify who caused the mob to spawn right

#

to then hide any mob without it

tacit glade Oct 8, 2022, 7:53 PM

#

You could probably store the entities in a map or smtn

rigid torrent Oct 8, 2022, 7:54 PM

#

i dont think a hashmap would be worth if they get immidiantly killed imo

#

i think ill do the tag thing

#

i just dont know how to add custom tags to mobs

tacit glade Oct 8, 2022, 7:56 PM

#

Thing is, with the map, you can then hide the entities from other players that join the server

rigid torrent Oct 8, 2022, 7:57 PM

#

yeah

#

so i just put the entities in a hashmap linked with the player

tacit glade Oct 8, 2022, 7:58 PM

#

Yea, or you can put the entities id's instead

#

To not cause memory leaks lol

rigid torrent Oct 8, 2022, 7:59 PM

#

how do u get the entities id

tacit glade Oct 8, 2022, 7:59 PM

#

.getId()

rigid torrent Oct 8, 2022, 7:59 PM

#

ok

#

will try

#

ill post results here

#

btw is there a packet to send to the player to make their hearts hardcore hearts

rigid torrent Oct 8, 2022, 8:25 PM

#

@tacit glade should i save the hashmap to a file?

rigid torrent Oct 8, 2022, 9:52 PM

#

wait why would i even need to use a hashmap

#

@tacit glade

tacit glade Oct 8, 2022, 9:58 PM

#

ig so you know who's entities are who's

rigid torrent Oct 8, 2022, 10:04 PM

#

wait hold on

#

        for (final Player nonViewingPlayer : /* Provide the other players that aren't meant to see the enemy here */) {
            ((CraftPlayer) nonViewingPlayer).getHandle().connection.connection.send(removeEntityPacket);
        }```

#

thats what i have so far

#

i just cant figure out what to do at the bottom

tacit glade Oct 8, 2022, 10:10 PM

#

at the bottom?

#

do you mean "/* Provide the other players that aren't meant to see the enemy here */"? @rigid torrent

rigid torrent Oct 8, 2022, 10:11 PM

#

yes

tacit glade Oct 8, 2022, 10:12 PM

#

List<Player> players = new ArrayList<>(Bukkit.getWorld(/*world name*/).getPlayers());
players.remove(player);

#

why not amirite

#

@rigid torrent

rigid torrent Oct 8, 2022, 10:12 PM

#

wait but

#

what about when a player joins the server

#

i can see their zombie then

tacit glade Oct 8, 2022, 10:12 PM

#

?

rigid torrent Oct 8, 2022, 10:13 PM

#

likie if it were the players in the world, after i joined, the code would have already ran and then they would be able to see my zombie

tacit glade Oct 8, 2022, 10:13 PM

#

what

rigid torrent Oct 8, 2022, 10:13 PM

#

im calling it on an on join event

#

so think about this

#

i join the server

#

my zombie gets hidden for all other players on the server

#

then if someone else joins

#

they are not a part of the list

tacit glade Oct 8, 2022, 10:14 PM

#

oh yeah

#

was gonna explain that

#

basically by storing all the entities in the map, you can then send the packet for removing the zombies

#

like this:

rigid torrent Oct 8, 2022, 10:17 PM

#

when im finished with this i am making an api for this because this is complicated

tacit glade Oct 8, 2022, 10:22 PM

#


    final Map<UUID, Integer> enemiesIds = new HashMap<>();

join event ->
    final Player player = event.getPlayer();
    final ClientboundRemoveEntitiesPacket clientboundRemoveEntitiesPacket = new ClientboundRemoveEntitiesPacket(this.enemiesIds.values().stream().mapToInt(Integer::intValue).toArray());
    ((CraftPlayer) player).getHandle().connection.connection.send(clientboundRemoveEntitiesPacket);

#

something like that @rigid torrent

rigid torrent Oct 8, 2022, 10:23 PM

#

the first line is in the class right

#

but just not in the EventHandler

tacit glade Oct 8, 2022, 10:23 PM

#

yea

rigid torrent Oct 8, 2022, 10:24 PM

#

alright imma try it out

#

so what exactly does the code do

#

just brief explenation

#

because i have no idea how to read that

tacit glade Oct 8, 2022, 10:24 PM

#

final ClientboundRemoveEntitiesPacket clientboundRemoveEntitiesPacket = new ClientboundRemoveEntitiesPacket(this.enemiesIds.values().stream().mapToInt(Integer::intValue).toArray());

#

that just creates the packet

#

and converts the "Integer" from the map into an array of int's

#

the Integer in the map refers to the entities id's

#

that you want to hide from the players

rigid torrent Oct 8, 2022, 10:25 PM

#

where do i put the players or the zombies

#

or does it already do that

#

do i add the zombie to the enemiesIds after spawning it

tacit glade Oct 8, 2022, 10:28 PM

#

rigid torrent do i add the zombie to the enemiesIds after spawning it

yea

#

actually I've got a better idea

#

    final Set<Integer> enemiesIds = new HashSet<>();

join event ->
    final Player player = event.getPlayer();
    final ClientboundRemoveEntitiesPacket clientboundRemoveEntitiesPacket = new ClientboundRemoveEntitiesPacket(this.enemiesIds.stream().mapToInt(Integer::intValue).toArray());
    ((CraftPlayer) player).getHandle().connection.connection.send(clientboundRemoveEntitiesPacket);```

#

@rigid torrent

rigid torrent Oct 8, 2022, 10:30 PM

#

how is this any different

tacit glade Oct 8, 2022, 10:31 PM

#

you don't need a key

#

less memory usage

#

and Set's have a smaller memory footprint than lists

rigid torrent Oct 8, 2022, 10:31 PM

#

thats smart

#

wait so how do i add the id to the set then

tacit glade Oct 8, 2022, 10:32 PM

#

.add

#

same as a list

rigid torrent Oct 8, 2022, 10:32 PM

#

enemiesIds.add(zombie.getId()); this would go after it spawns

tacit glade Oct 8, 2022, 10:32 PM

#

yep

rigid torrent Oct 8, 2022, 10:33 PM

#

rigid torrent my zombie gets hidden for all other players **on the server**

but i still dont understand how that fixes this

tacit glade Oct 8, 2022, 10:33 PM

#

because when a player joins, it will send the remove packet to them - for all the zombies that are going to be hidden

rigid torrent Oct 8, 2022, 10:33 PM

#

and for existing players?

tacit glade Oct 8, 2022, 10:33 PM

#

no need to worry about that, the code below the spawn code should do that

#

if you kept the ClientboundRemoveEntitiesPacket there

rigid torrent Oct 8, 2022, 10:34 PM

#

where is there

#

oh

#

i still dont have that one

#

i dont know what to put in the bottom one remember

tacit glade List<Player> players = new ArrayList<>(Bukkit.getWorld(/*world name\*/).getPlaye...

@rigid torrent

yeah but that would still be current players

tacit glade Oct 8, 2022, 10:35 PM

#

?

rigid torrent Oct 8, 2022, 10:35 PM

#

like wouldnt that still only apply to current players

tacit glade Oct 8, 2022, 10:35 PM

#

it will hide it for everyone in the world except the player that joined

#

can you send me your current code?

rigid torrent Oct 8, 2022, 10:36 PM

yeah but i have not added the ClientboundRemoveEntitiesPacket

#

You fine with the entity being completely silent?

rigid torrent Oct 9, 2022, 12:57 AM

#

yeah sure its only like 2 zombies and a spider at the very beginning of the game so i dont mind

tacit glade Oct 9, 2022, 12:57 AM

#

.setSilent(true)

rigid torrent Oct 9, 2022, 12:58 AM

#

alright

#

when u do player.playSound, does it only play for the player u play it on

tacit glade Oct 9, 2022, 12:59 AM

#

Yeah

rigid torrent Oct 9, 2022, 12:59 AM

#

perfect

#

are u familiar with multi world support

tacit glade Oct 9, 2022, 1:00 AM

#

?

rigid torrent Oct 9, 2022, 1:00 AM

#

like tping the player into custom worlds

#

like multiverse does

tacit glade Oct 9, 2022, 1:00 AM

#

ah

rigid torrent Oct 9, 2022, 1:01 AM

#

do u know

tacit glade Oct 9, 2022, 1:01 AM

#

pretty sure you can just do "player.teleport(new Location(/* The world */, x, y, z))"

rigid torrent Oct 9, 2022, 1:02 AM

#

how would u get the world

tacit glade Oct 9, 2022, 1:02 AM

#

Bukkit.getWorld("world name")

rigid torrent Oct 9, 2022, 1:02 AM

#

alright

#

is it possible to make somebody see hardcore hearts on their screen using packets

tacit glade Oct 9, 2022, 1:05 AM

#

Yeah

rigid torrent Oct 9, 2022, 1:05 AM

#

how would that work

tacit glade Oct 9, 2022, 1:05 AM

#

lemme find it

rigid torrent Oct 9, 2022, 1:06 AM

#

u dont have to write the code but u can link me to a javadoc or something

tacit glade Oct 9, 2022, 1:10 AM

#

Probably going to have to intercept the "ClientboundLoginPacket" @rigid torrent

#

That contains all the information about the server when the player first joins

rigid torrent Oct 9, 2022, 1:11 AM

#

and hardcore hearts are through the server.properties so that make sense i guess

tacit glade Oct 9, 2022, 1:11 AM

#

yea
