## Instant-Shield-Break v1.0
\n**NETHPOT PVP \u00b7 FABRIC MOD \u00b7 CLIENT-SIDE**<\/p>\n

Auto-breaks enemy shields in nethpot PvP by swapping to an axe at the exact moment of attack,
\nthen reverting instantly \u2014 all within a single tick. No GUI, no keybinds, always on.<\/p>\n

**Tags:** Fabric API \u00b7 Java \u00b7 MC 1.19\u20131.21 \u00b7 1-tick swap \u00b7 Always active \u00b7 Zero flicker<\/p>\n

—<\/p>\n

### \u2699\ufe0f How the Swap Works<\/p>\n

A five-step process that occurs within a single tick:<\/p>\n

1. **Attack fired** \u2014 player hits enemy
\n2. **Shield check** \u2014 `isUsingItem()` detects if the target is raising a shield
\n3. **Swap to axe** \u2014 `@Inject HEAD` swaps the held item to an axe
\n4. **Axe hits** \u2014 shield is disabled
\n5. **Revert slot** \u2014 `@Inject RETURN` swaps back to the original item instantly<\/p>\n

—<\/p>\n

### \ud83d\udce6 Module Breakdown<\/p>\n

**ShieldDetector** (`util\/ShieldDetector.java`)
\nChecks if the target player is actively raising a shield via `isUsingItem()` + item identity
\ncheck. Catches the intent before the 5-tick raise delay, ensuring no missed hits.<\/p>\n

**InventoryScanner** (`util\/InventoryScanner.java`)
\nScans hotbar slots `0\u20138` first, then main inventory slots `9\u201335`. Maintains a cached
\nlast-used axe slot for instant lookup on repeated attacks. Supports any modded axe
\nextending `AxeItem`.<\/p>\n

**SwapHandler** (`handler\/SwapHandler.java`)
\nOrchestrates the full swap sequence. Guards against spam with a `150ms` cooldown. Sends a
\nvanilla `UpdateSelectedSlotC2SPacket` for server sync. Reverts in the same call-stack frame
\n\u2014 zero extra ticks.<\/p>\n

**Attack Mixin** (`mixin\/ClientPlayerInteractionManagerMixin.java`)
\nHooks into `attackEntity()` at `HEAD` (pre-packet) and `RETURN` (post-packet). Only
\nintercepts `PlayerEntity` targets \u2014 mob attacks pass through unmodified.<\/p>\n

**Config** (`config\/ShieldBreakConfig.java`)
\nGSON-backed JSON config at `config\/instant-shield-break.json`. Supports `enabled` toggle,
\n`cooldownMs` tuning, and `debugLogging` for verbose output. Auto-creates defaults on first
\nlaunch.<\/p>\n
