๐ก๏ธ Instant-Shield-Break
by shubham96__
Instant-Shield-Break, a Fabric client mod, swaps to an axe for the exact tick a player attacks a shield-raising opponent, then swaps back.
What it does
When the attacked player is actively raising a shield, the mod checks the target and switches the held item to an axe, so the hit disables the shield. The swap is reverted in the same call-stack frame, so the original item is back in hand without any extra ticks. A 150ms cooldown guards against repeated swapping during spam attacks, and the mod only intercepts player targets, so attacks on mobs pass through unchanged.
The mod targets PvP situations such as nethpot fights, where the shield check catches the intent before the usual five-tick raise delay. Axe lookup scans the hotbar first and then the main inventory, and it remembers the last axe slot used for quick repeat attacks. Modded axes that extend AxeItem are also recognized. The swap is sent to the server with the vanilla slot-update packet, so the server stays in sync.
Installation needs Fabric and Prism Mod Menu. Only the player's game needs it, and servers run without it. The code is under the MIT License and is not open source, and builds exist for 1.19 โ 1.21.11 across 24 release versions.
Key features
Shield detection
Before any swap takes place, the mod checks if the target player is in the middle of raising a shield.
Axe swap and revert
Switches to an axe at the moment of the hit and returns the original item within the same tick.
Inventory scanning
Searches hotbar slots 0 to 8, then main inventory slots 9 to 35, and caches the last axe slot used.
Spam cooldown
A 150ms cooldown limits how often the swap can fire during rapid attacks.
