From b343ce7e1b6f2ca6dc1fbf91cf3bc908dde3f460 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 25 May 2026 12:57:54 +0000 Subject: [PATCH] Re-architect and fix spoint engine core - Modularized `src/physics/World.js` into `BodyManager.js` and `QueryManager.js`. - Modularized `src/sdk/TickHandler.js` into `SnapshotSystem.js` and `MovementSystem.js`. - Fixed `player-divisor-dt-bug` ensuring smooth horizontal movement when physics is throttled. - Implemented supervisor try/catch boundaries in `TickHandler` and `AppRuntime` for "uncrashable" behavior. - Ensured all source files are under the 200-line maintainability limit. - Fixed memory leaks in `SnapshotSystem` by properly clearing disconnected player state. - Improved `AppLoader` by removing redundant imports. - Corrected `MovementSystem` state initialization. - Verified system stability with a successful server boot test.
