🗡 SMS Swap (Client-Only)

SMS Swap is a lightweight client-side Fabric mod for Minecraft 1.21.4 that helps you execute fast PvP combos by swapping to a configured hotbar slot, waiting a small delay (for server sync), performing the action, then returning to your previous slot automatically.

✅ Features

  • 100% client-side (no server install required)

  • Hit macro (always triggers):
    swap → delay → vanilla attack → delay → swap back
    Uses the vanilla attack behavior (same as pressing LMB): works on entities, blocks, and air.

  • 3 separate Use macros (multiple keybinds):
    swap → delay → vanilla use → delay → swap back

  • Configurable delays (ticks)

  • Automatic return to your previous hotbar slot

  • Settings persist in .minecraft/config/sms-swap.json

  • In-game configuration via commands + tab completion

⌨ Keybinds (Controls → SMS Swap)

Default bindings (change in Controls):

  • Use Macro 1: X

  • Use Macro 2: Left Alt

  • Use Macro 3: C
