Class ChatMessageC2SPacket

java.lang.Object
net.minecraft.network.packet.c2s.play.ChatMessageC2SPacket
All Implemented Interfaces:
Packet<ServerPlayPacketListener>
public class ChatMessageC2SPacket extends Object implements Packet<ServerPlayPacketListener>
A packet used to send a chat message to the server.

This truncates the message to at most 256 characters before sending to the server on the client. If the server receives the message longer than 256 characters, it will reject the message and disconnect the client.

If the message contains an invalid character (see isValidChar) or if the server receives the messages in improper order. the server will reject the message and disconnect the client.

Messages that took more than

invalid @link 
SignedMessage#SERVERBOUND_TIME_TO_LIVE
to reach the server are considered expired and log warnings on the server. If the message takes more than
invalid @link 
SignedMessage#CLIENTBOUND_TIME_TO_LIVE
to reach the clients (including the time it took to reach the server), the message is not considered secure anymore by the clients, and may be discarded depending on the clients' options.
