ClientBlockGuarder

Protect your builds from your own misclicks.

Choose any blocks in the config screen and this mod makes them unbreakable for you. When you try to break one, a small message appears above your hotbar and the block stays intact.

Features

• Register blocks you want to protect (chests, beacons, spawners, your build's key blocks, …)
• A small "This block is set as unbreakable" message is shown when you try to break a protected block
• Works in both Survival and Creative
• Config screen via Mod Menu:
  • Global ON/OFF toggle
  • Add a block by ID (e.g. minecraft:chest)
  • "Add Targeted Block" button – aim at a block in-world, then add it with one click
  • Click a registered block in the list to remove it
• Japanese and English translations included

How to use

1. Open Mod Menu → ClientBlockGuarder → Config
2. Add the blocks you want to protect
3. Try to break one – it won't break

Notes

• The block break is cancelled on your client, so the break request is never sent to the server.
• This only stops your own block breaking. Explosions, other players, or other mods that break blocks directly are not affected.
• Mod Menu is recommended (it is how you open the config screen). Without it you can edit the JSON file by hand.

Requirements

• Minecraft 26.1.2
• Fabric Loader
• Java 25
• Mod Menu (optional, recommended)
