Play

Clientbound

Open Sign Editor

Sent when the client has placed a sign and is allowed to send Update Sign. There must already be a sign at the given location (which the client does not do automatically) - send a Block Update first.

Packet ID State Bound To Field Name Field Type Notes
0x31 Play Client Location Position
Is Front Text Boolean Whether the opened editor is for the front or on the back of the sign

Serverbound

Update Sign

This message is sent from the client to the server when the “Done” button is pushed after placing a sign.

The server only accepts this packet after Open Sign Editor, otherwise this packet is silently ignored.
