Description

Universal Input Sync

Universal Input Sync is a lightweight, client-side QoL (Quality of Life) mod that fixes input race conditions in Minecraft, eliminating "dead clicks" during high-APM gameplay.

⚙️ How It Works

In vanilla Minecraft, rapid hotbar switching and clicking within the exact same frame (<16ms) causes state desyncs. This mod fixes the root cause by enforcing deterministic ordering. It guarantees your slot update (UpdateSelectedSlotC2SPacket) is strictly processed before your interaction packet, preventing ghost clicks.

✨ Features

  • True 1:1 Input: Zero macros, no packet spoofing, no hacking, and no artificial CPS.
  • Universal QoL Fix: Applies natively to all items globally.
  • Client-Side Only: Works on any vanilla server without server-side installation.

📦 Requirements

  • Minecraft 1.21.4 (Fabric API)

Disclaimer: This mod uses strictly vanilla packet structures with zero automation. However, exceptionally fast, non-human input consistencies may still trigger heuristic flags on aggressively tuned anti-cheats (e.g., GrimAC).
