About this project
What does Shield Breaker add?

🚀 Shield Breaker
Automatically swaps to your axe the moment you hit a shield, disabling enemy defenses instantly.
🌟 Key Features
A streamlined overview designed to show players exactly why they need your mod:
- 🪓 Instant Shield Breaker: Automatically detects when an opponent is blocking with a shield. The moment you strike, it instantly swaps to the nearest axe in your hotbar to disable their defense, then seamlessly switches back to your weapon.
- 💥 Stun Slam: Enable Stun Slam in the Shield Breaker GUI to chain a shield-breaking axe hit into a mace
smash while falling. Keep both an axe and a mace in your hotbar. - 🎨 Modern GUI: Press
Right CTRL(Default) to open a clean, intuitive interface to easily manage your settings and toggle features without typing complex commands. - ⚡ PvP-Optimized Response: Built with client-side efficiency in mind, ensuring split-second weapon switches mid-combat with zero input lag or FPS drops.
🛡️ Multiplayer & Server Opt-In
Modrinth Rule 3.3d: Automatic shield-breaking is a server-side opt-in feature. By default it is disabled on dedicated servers.
- Singleplayer / LAN: Always works, no setup needed.
- Dedicated server: Works only if the server operator installs the mod and sets allow_shield_breaker=true in config/shieldbreaker-server.properties (default: false). If not allowed, you will see in chat: Disabled on this server. Server opt-in required. and Blocked... with a 3s anti-spam cooldown - the mod will not swap or attack.
📖 How to Use
💡 Quick Tip: It is highly recommended to restart your game after the initial setup for all configurations to sync properly.
- Launch Minecraft and press Right CTRL to bring up the main mod menu.
- Toggle Shield Breaker on, then enable Stun Slam in the GUI if you want aerial axe-to-mace combos.
- Bind a custom hotkey (e.g., the
Gkey) to quickly toggle the mod on and off mid-combat without opening the menu.
