How do I change protocol for a modded server?

[Gibstick]

\source\src\protocol.h
Line 8,

Code:

#define PROTOCOL_VERSION 1129 // bump when protocol changes (use negative numbers for mods!)

You can change 1129 to a negative number so normal clients can still use the /modconnect command.

These comments at the top of server.h are also useful.

Code:

#define SERVER_PROTOCOL_VERSION (PROTOCOL_VERSION) // server without any gameplay modification //#define SERVER_PROTOCOL_VERSION (-PROTOCOL_VERSION) // server with gameplay modification but compatible to vanilla client (using /modconnect) //#define SERVER_PROTOCOL_VERSION (PROTOCOL_VERSION) // server with incompatible protocol (change PROTOCOL_VERSION in file protocol.h to a negative number!)
