Packet API

Binary Stream Object API

Create binary stream

BinaryStream bs;

Write to binary stream

There you can get information what's needed to write in your packet! Protocol Documentation & Bedrock Protocol

bs.writeXXXXX(value);

Building packet from binary stream

std::shared_ptr<Packet> packet = MinecraftPackets::createPacket(MinecraftPacketIds::Text); // Create TextPacket
packet->read(bs); // Parse binary stream

Sending packet

To specific player

player->sendNetworkPacket(*packet);

To all players

Global<Level>->sendPacketForAllPlayers(*packet);

Demo Code

Simple implementation of Text Packet

BinaryStream bs; // Create binary stream
bs.writeUnsignedChar(0); // Text type
bs.writeBool(false); // Needs translation
bs.writeString(""); // Source name
bs.writeString("Hello world!"); // Message
bs.writeString(""); // XUID
bs.writeString(""); // Platform chat id
std::shared_ptr<Packet> packet = MinecraftPackets::createPacket(MinecraftPacketIds::Text); // Create packet
packet->read(bs); // Parse binary stream
player->sendNetworkPacket(*packet); // Send packet to specific player
