Host Relay Prototype

The point of this is to be a dedicated relay server for multiplayer applications with two needs:

• Reliable, ordered data transmission (TCP-like)
• Unreliable data transmission (UDP)

This exists to allow players to join games that don't need dedicated server logic.

DISCLAIMER: This is a hacked together prototype and should not be used in production! Code will change without warning and nothing is guaranteed!

What this doesn't have

• Anti-cheat
• Data sanity checking
• Anti-spam/congestion control
• Complex authentication

Basic design

• TCP socket listening for connections
  • Each connection is stored
• UDP socket to listen for messages from each player
  • Broadcast each received message to the rest of the connected players

Building & running

go run .\cmd\server

To run a test client in TCP mode:

go run .\cmd\client
# Input strings and press enter to send. Type `exit` to quit.

For UDP:

go run .\cmd\client -udp
# Input strings and press enter to send. Type `exit` to quit.
