PacketEntities, Unreleased!

PlatformsPacketEventsMinecraft Versions

PacketEntities is a high-performance, developer library designed to abstract Minecraft's protocol-level entity system. Built on top of PacketEvents, it allows you to easily create, control, and manipulate packet-based entities without the overhead of heavy server-side entities.

Whether you are targeting backend game servers or proxy-side systems, PacketEntities handles the heavy lifting of version-agnostic metadata/object data, spawn packets, and entity tracking seamlessly across Minecraft 1.9.4 through the latest versions.

Getting Started

1. Add Dependencies

First, ensure you have PacketEvents shaded or installed on your platform. Then, add PacketEntities to your build system and relocate it to avoid conflicts with other plugins:

Gradle kotlin dsl

plugins {
id("java")
id("com.gradleup.shadow") version "9.1.0"
}
repositories {
// TODO (not published anywhere yet, probably going to use jitpack?)
}
dependencies {
implementation("dev.threeadd.packetentities:spigot:1.0-SNAPSHOT")
}
tasks {
shadowJar {
archiveFileName = project.name +"-"+ project.version +".jar"
relocate("dev.threeadd.packetentities.", "dev.threeadd.packetentitiestest.packetentities.")
}
}

Maven xml

TODO

2. Setup the api

Choose a platform (The example uses paper, but other platforms have similar setups)

// in YourPlugin.java@OverridevoidonEnable() {
PacketEntitiesAPISettingssettings = newPacketEntitiesAPISettings();
PaperPacketEntitiesPlatformplatform = newPaperPacketEntitiesPlatform(this, settings);
PacketEntities.init(platform);
// other logic...
}

Example Usage

Entities

for spawning a player entity

Locationloc = /*...*/;
UUIDuuid = UUID.randomUUID();
ProtocolEntityentity = ProtocolEntity.builder()
.entityType(EntityTypes.PLAYER)
.extensions(extensions -> extensions
.extension(newPlayerExtension(
newUserProfile(uuid, "notch"),
GameMode.CREATIVE,
67,
true,
Component.text("Notch", NamedTextColor.GREEN)
))
.extension(newTickExtension())
.extension(newTickVelocityExtension())
)
.viewers(viewers -> viewers
.viewers(Bukkit.getOnlinePlayers().stream().map(Player::getUniqueId).toList())
)
.meta(meta -> {
meta.get(EntityMetaFields.Player.SHARED_FLAGS).setGlowing(true);
meta.set(EntityMetaFields.Player.SCORE, 200);
meta.set(EntityMetaFields.Player.POSE, EntityPose.SITTING);
})
.uuid(uuid)
.velocity(newVector3d(1, 1, 1))
.version(PacketEvents.getAPI().getServerManager().getVersion())
.buildAndSpawn(ProtocolWorld.of(loc.getWorld().getName()), loc);

Meta

from packet

WrapperPlayServerEntityMetadatametadataPacket = /*...*/;
ProtocolEntityMetametadata = newProtocolEntityMeta(/*...*/); // provided you know the entity type of the packet's datametadata.setDataFromPacket(metadataPacket);

to packet

ProtocolEntityMetametadata = /*...*/;
intentityId = /*...*/;
ServerVersionversion = PacketEvents.getAPI().getServerManager().getVersion();
WrapperPlayServerEntityMetadatametadataPacket = metadata.createPacket(entityId, version);

Credits

During this project, EntityLib was used as a base to start development from, though PacketEntities was built from scratch.

PacketEntities, Unreleased!
PlatformsPacketEventsMinecraft Versions
PacketEntities is a high-performance, developer library designed to abstract Minecraft's protocol-level entity system.
Built on top of PacketEvents, it allows you to easily create, control, and manipulate packet-based entities without the overhead of heavy server-side entities.
Whether you are targeting backend game servers or proxy-side systems,
PacketEntities handles the heavy lifting of version-agnostic metadata/object data,
spawn packets, and entity tracking seamlessly across Minecraft 1.9.4 through the latest versions.
Getting Started
1. Add Dependencies
First, ensure you have PacketEvents shaded or installed on your platform. Then,
add PacketEntities to your build system and relocate it to avoid conflicts with other plugins:
Gradle kotlin dsl
plugins {
id("java")
id("com.gradleup.shadow") version "9.1.0"
}
repositories {
// TODO (not published anywhere yet, probably going to use jitpack?)
}
dependencies {
implementation("dev.threeadd.packetentities:spigot:1.0-SNAPSHOT")
}
tasks {
shadowJar {
archiveFileName = project.name +"-"+ project.version +".jar"
relocate("dev.threeadd.packetentities.", "dev.threeadd.packetentitiestest.packetentities.")
}
}
Maven xml
TODO
2. Setup the api
Choose a platform (The example uses paper, but other platforms have similar setups)
// in YourPlugin.java@OverridevoidonEnable() {
PacketEntitiesAPISettingssettings = newPacketEntitiesAPISettings();
PaperPacketEntitiesPlatformplatform = newPaperPacketEntitiesPlatform(this, settings);
PacketEntities.init(platform);
// other logic...
}
Example Usage
Entities
for spawning a player entity
Locationloc = /*...*/;
UUIDuuid = UUID.randomUUID();
ProtocolEntityentity = ProtocolEntity.builder()
.entityType(EntityTypes.PLAYER)
.extensions(extensions -> extensions
.extension(newPlayerExtension(
newUserProfile(uuid, "notch"),
GameMode.CREATIVE,
67,
true,
Component.text("Notch", NamedTextColor.GREEN)
))
.extension(newTickExtension())
.extension(newTickVelocityExtension())
)
.viewers(viewers -> viewers
.viewers(Bukkit.getOnlinePlayers().stream().map(Player::getUniqueId).toList())
)
.meta(meta -> {
meta.get(EntityMetaFields.Player.SHARED_FLAGS).setGlowing(true);
meta.set(EntityMetaFields.Player.SCORE, 200);
meta.set(EntityMetaFields.Player.POSE, EntityPose.SITTING);
})
.uuid(uuid)
.velocity(newVector3d(1, 1, 1))
.version(PacketEvents.getAPI().getServerManager().getVersion())
.buildAndSpawn(ProtocolWorld.of(loc.getWorld().getName()), loc);
Meta
from packet
WrapperPlayServerEntityMetadatametadataPacket = /*...*/;
ProtocolEntityMetametadata = newProtocolEntityMeta(/*...*/); // provided you know the entity type of the packet's datametadata.setDataFromPacket(metadataPacket);
to packet
ProtocolEntityMetametadata = /*...*/;
intentityId = /*...*/;
ServerVersionversion = PacketEvents.getAPI().getServerManager().getVersion();
WrapperPlayServerEntityMetadatametadataPacket = metadata.createPacket(entityId, version);
Credits
During this project, EntityLib was used as a base to start development from, though PacketEntities was built from scratch.
