CLASS net/minecraft/class_7438 net/minecraft/network/packet/s2c/play/ChatMessageS2CPacket
	COMMENT A packet used to send a chat message to the clients.
	COMMENT
	COMMENT <p>The content is not wrapped in any way (e.g. by {@code chat.type.text} text); the
	COMMENT raw message content is sent to the clients, and they will wrap it (see {@link
	COMMENT net.minecraft.client.gui.hud.ChatHudListener#format}.) If custom formats are needed,
	COMMENT either send it as a {@link GameMessageS2CPacket game message} or use a server resource pack.
	COMMENT
	COMMENT <p>Messages that took more than {@link #TIME_TO_LIVE} to reach the clients are
	COMMENT considered expired. This is measured from the time the client sent the chat message
	COMMENT to the server. Note that unlike {@link
	COMMENT net.minecraft.network.packet.c2s.play.ChatMessageC2SPacket} expired messages are not
	COMMENT discarded by the clients; they instead log a warning.
	COMMENT
	COMMENT <p>Chat messages have signatures. It is possible to use a bogus signature - such as
	COMMENT {@link NetworkEncryptionUtils.SignatureData#NONE} - to send a chat message; however
	COMMENT if the signature is invalid (e.g. because the text's content differs from the one
	COMMENT sent by the client, or because the passed signature is invalid) the client will
	COMMENT log a warning. See {@link NetworkEncryptionUtils#updateSignature} for how the message
	COMMENT is signed.
