Net Crowd Stress Test

A plaza full of walking players on one server, built on the Kaigen Engine, a high performance, cross-platform 3D engine written in C, to stress-test its netcode with tens of thousands of connected players. The same binary is the server, the client and the bot load generator.

Requirements

The project needs the Kaigen Engine, which is in closed beta, at version 0.7.0 or newer. The netcode this demo uses ships in 0.7.0, which is not released yet.

Run

hz is a link to your engine checkout at the project root (it is not part of this repository).

hz/hzbuild run                       # host: a server and a local client in one process
hz/hzbuild run -- --server           # a dedicated server
hz/hzbuild run -- --join <ticket>    # a client joining a server

WASD walks. The panel in the top-left shows the server's player count and tick times, and this client's snapshot rate and round trip.

--bots turns the binary into a load generator that connects many simulated players to a server (native platforms). Its flags are read in src/net_crowd/nc_bots.c.

Layout

• src/net_crowd/: the demo (simulation, bots, map, rendering, recording)
• tests/: the project's tests (hz/hzbuild test run)
• assets/net_crowd/: the player characters
• gameplay_blocks/: the engine's gameplay module, vendored
