Here you go dude.

Multiplayer Barebones

That should work for you over LAN. That is as simple as it gets man, enjoy. Welcome to the joys of multiplayer, the fun has only begun. Don't be fooled by the 175 lines of code, you will have a monster in your closet. But the code is simple and small enough to help figure out how to get started.

The first thing you will have to figure out is what functions/actions are being ran on the host/server and what is being ran on the client. From there life gets easier.

Use Cursor keys to move.

When you run from WED for Host this should be Command Line:
simple.wdl -nx 50 -d hires -diag -cl -sv

For Clients on LAN:
simple.wdl -nx 50 -d hires -diag -cl
