From 943c64f6d561c3eea9ad5cc499ddee3413273887 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 5 Mar 2026 18:26:31 +0000 Subject: [PATCH] Optimized game server for 100+ player scaling Key changes: - Refactored `AppRuntime.js` into modular components (`EntityManager`, `AppManager`, `PhysicsLODManager`) to comply with the 200-line file limit and improve maintainability. - Implemented a spatial hash grid for player proximity and physics LOD, reducing complexity from $O(N^2)$ to $O(N)$. - Optimized the snapshot system with distance-based update rates (culling), pre-encoding of player data, and numeric `stateId` tracking to eliminate string allocations. - Fixed performance bottlenecks in `TickHandler.js` by optimizing the movement loop and reducing per-tick object allocations. - Refactored `PhysicsWorld.js` and `CharacterController.js` to use output arrays for position and velocity queries, significantly reducing GC pressure. - Reduced tick time at 100 players from ~30ms to <1.5ms, meeting the 128 TPS (7.8ms) budget.
