Solved Get all NPC's as a list

Hello.
So i am trying to make a NPC plugin, but now i can't find a method, how i can get all NPC's (The Npc's are EntityPlayers/ServerPlayers) as a list (without setting them manuely in a list) like the 'Bukkit.getOnlinePlayers()' method.
Here is the code how i created my NPC's:

Code:

MinecraftServer server = ((CraftServer) Bukkit.getServer()).getServer();
ServerLevel world = ((CraftWorld) player.getWorld()).getHandle();
GameProfile gameProfile = new GameProfile(UUID.randomUUID(), "Bot");

SkinFetcher.Skin skin = new SkinFetcher().defaultSkin();
gameProfile.getProperties().put("textures",new Property("textures",skin.getValue(),skin.getSignature()));

ServerPlayer serverPlayer = new ServerPlayer(server,world,gameProfile,null);

serverPlayer.moveTo(player.getLocation().getX(), player.getLocation().getY(), player.getLocation().getZ(), player.getLocation().getPitch(), player.getLocation().getYaw());

if (player.getWorld().getName().equals(serverPlayer.level.getWorld().getName())) {
            ServerGamePacketListenerImpl connection = ((CraftPlayer) player).getHandle().connection;

            connection.send(new ClientboundPlayerInfoPacket(ClientboundPlayerInfoPacket.Action.ADD_PLAYER, serverPlayer));
            connection.send(new ClientboundAddEntityPacket(serverPlayer));
            connection.send(new ClientboundEntityEventPacket(serverPlayer, (byte) (serverPlayer.getYHeadRot() * 256 / 360)));

            SynchedEntityData watcher = new SynchedEntityData(serverPlayer);
            watcher.define(new EntityDataAccessor<>(17, EntityDataSerializers.BYTE), (byte) 127);
            connection.send(new ClientboundSetEntityDataPacket(serverPlayer.getId(), watcher, true));

            new BukkitRunnable() {
                @Override
                public void run() {
                    connection.send(new ClientboundPlayerInfoPacket(ClientboundPlayerInfoPacket.Action.REMOVE_PLAYER, serverPlayer));
                }
            }.runTaskLater(Main.plugin, 50);
        }

Thanks for help.

 

So I assume the ServerPlayer is the NPC then, right? If so, I'd create a collection like a List<ServerPlayer> somewhere globally accessible then use that. Maybe if you need to associate them somehow to some sort of identifying marker, use a Map<(index data type), ServerPlayer> instead then.

 

The problem with this is you can only use this in the plugin where the NPC is created from, but i want to use it in other plugins too

 

So i did it like this https://www.spigotmc.org/threads/get-variable-from-another-plugin.365747/ , but now it gave me an error:

What does that mean?

 

You could always make an API.

Yea, unfortunately peoples' expertise here tends to be in the area of Java, not mind reading
