Overview

SyncBoost optimizes meaningless server-side hopper polling when idle. Container GUI synchronization is left entirely to vanilla to ensure gameplay correctness.

Core Strategy (Delivery Safe Version)

  1. Container Sync: Does not intercept sendContentUpdates(), avoiding revision / property / cursor protocol risks
  2. Hopper Idle Skip: Only skips 2 ticks when ALL of the following are met:
    • Server-side
    • Hopper not on cooldown (transferCooldown == 0 / Mojang: cooldownTime == 0)
    • Hopper itself is empty
    • An Inventory / Container exists directly above
    • Content hash of the above Inventory has not changed
  3. Cross-Dimension Isolation: Tracking key includes dimension hash to prevent same-coordinate crosstalk

What It Does NOT Do

  • Does not rewrite container network synchronization
  • Does not skip item pickup path (passes through to vanilla when no container above)
  • Does not modify hopper cooldown semantics
