How It Works

Message Capture:

Uses packet interception to capture ALL chat messages
Includes player chat, command errors, server notifications, join/leave messages
No messages are missed - captures everything the server sends

Message Storage:

Stores last 100 messages per player with timestamps
In-memory only (cleared on server restart)

Message Format:

Default:           [14:23:15] BeyondSmash: Hello world!
No timestamps:     BeyondSmash: Hello world!
No usernames:      [14:23:15] Hello world!
Both off:          Hello world!

Filter Types:

ALL - Both player and system messages
PLAYER - Only chat from players
SYSTEM - Server messages (command errors, joins, leaves, notifications)

Clear Function:

Only clears messages in current filter mode
Shows confirmation dialog before clearing
Plays sound effect when messages are cleared

Troubleshooting

Chat log is empty Send some messages in chat first, then run /copychat again. The plugin only captures messages while it's running.

Clear button does nothing Normal when there are no messages in the current filter.

Settings won't save Don't edit config.json while the game is running. The plugin saves on every change.
