LT: Elixir for Gaming! Using Network to Power a Sophisticated Multiplayer Simulation
summary
A server‑authoritative multiplayer simulation built in Elixir over two years uses GenServer per AI processes coordinated by higher‑level supervisors so group tactics run without blocking the main loop, and supervisors plus hot code swapping enable a pragmatic let it crash deployment model. Networking uses simple pattern‑matched binaries rather than heavyweight stacks and a custom binary protocol handles client inputs and deltas. The prototype runs live simulations with independent AI memory, coordinated strategy, and restarts on failures, showing Elixir and OTP actually scale for dedicated‑server games.
