As part of the Game Design book of lenses book, the first lens is Emotion.

What emotion do I want from a game built on HackMatrix? I want a feeling of Connectivity and Competence.

To generate a feeling of Connectivity, the engine must support multiplayer... players can join up to solve computer problems (programming, Linux stuff, even graphics design and asset creation).

So my current focus based on the game design book is going to be multiplayer.

Me: First, the networking library. I'm currently using ZMQ for other purposes. Is that too high level? What are the tradeoffs vs using the other ones you suggested?

Ok. I'm choosing ENet. Reddit says it is battle tested.

I'm keeping a design doc of decisions on the new multiplayer branch: https://github.com/collinalexbell/HackMatrix/tree/multiplayer

I asked claude to generate Client, Server, and Gui classes:

HackMatrix already has a preexisting Imgui class with tabs that Claude didn't know about. I had claude rewrite the Gui class so that it can plug into the engineGui class.

Barebones GUI works. Connect button still needs something to call, but that will be implemented in the Client class. I also thing the GUI needs an option to make a particular instance into a server.

Got a used laptop, installed Arch. HackMatrix is the only WM installed 😆.

Test environment all set up to start hacking on multiplayer in earnest. Lfg

Client and Server compile now. Had to add enet impl to engine.cpp.

Client and Server basis connection works.

Server starts (no connections notconnected

Add client info on another machine ready-to-connect

Connected connected

Server also sees 1 connection client

Position commands are getting sent.
