Find Your First Desync in 15 Minutes

说明与用途

Tickwise 通过记录每帧哈希、比较记录和差异化状态转储，帮助开发者快速定位确定性多人游戏中的首次分歧点，将调试时间从数周缩短到数分钟。

问题

Debugging a desync in deterministic multiplayer games is expensive because the symptom appears far from the cause and reproducing the exact run is hard.

结果

Tickwise reduces desync debugging from weeks to minutes by automating recording, comparison, and state diffing, enabling quick identification of the exact field causing divergence.

工作流

• Record inputs and per‑tick hashes on each client into .rec files.
• Run tickwise compare a.rec b.rec to find the first tick where hashes disagree and which hash caught it.
• Replay each recording in your own loop, dumping state at the reported tick into .dump files.
• Run tickwise diff a.dump b.dump to list all differing fields and their values.
• Investigate the differing fields to fix the underlying determinism bug.

证据

Tickwise is a Rust library and a command line tool. The library sits inside your game loop and watches. It never runs your simulation and never touches your netcode.
