# tMock-Server: reconstructing Terraria server handshakes

> tMock-Server is an unfinished C++ reimplementation of the Terraria server's initial network flow. It uses socket code and packet classes to accept connections, check protocol versions, request passwords, and assign player slots; the README records packet IDs, fields, directions, and structures informed by traffic analysis.
