Sentry Blocks 1.21+

Protecting your Minecraft creations doesn’t have to mean cluttered walls or visible traps. The Sentry Blocks Addon introduces invisible, automated protection for Minecraft Bedrock Edition (MCPE) players who value both design and defense. With this addon, your world gains unseen guardians that activate only when danger appears — giving you safety, style, and peace of mind all at once.

The Sentry Blocks Addon is a lightweight defense system that blends seamlessly into any Minecraft world.
It replaces bulky defense setups with smart blocks that look like ordinary materials but contain hidden sentry mechanisms. When triggered by nearby hostile mobs or configured targets, these blocks come alive to defend your base.

It’s perfect for:

• Survival players who want protection without heavy redstone builds.
• Creative builders who prefer smooth, aesthetic designs.
• Realm and server players seeking reliable base security.

This addon turns ordinary building blocks into silent guardians — a brilliant mix of creativity and functionality.

You don’t need complex wiring or experimental features to use this addon. Here’s how it behaves once installed.

Stealth Activation and Detection

Sentry Blocks stay disguised until an enemy enters range. Your castle walls or modern towers will look untouched — but underneath, an invisible defense system quietly waits. It’s smart, automatic, and completely hidden from plain sight.

Powering and Configuration

To activate a block, simply connect it to redstone power. Once charged, it becomes “tamed” and starts scanning for threats.
Players can easily choose between:

• Mob Mode – responds only to hostile creatures.
• Mob + Player Mode – useful for PvP servers or protected zones.

Autonomous Base Defense

After activation, sentries work 24 hours a day, even when you’re far from base. They automatically engage nearby threats, keeping farms, villagers, and storage rooms safe while you explore or mine peacefully.

This addon’s charm lies in its balance of simplicity and sophistication.
Below are the standout features that make Sentry Blocks Addon a must-have in your MCPE toolbox.

Hidden Defense System That Blends Seamlessly

Your base stays beautiful — no traps, no exposed turrets. Sentry Blocks mimic real blocks until danger appears.

Customizable Appearance

Craft at the Assembly Bench using different materials to match your world’s style — stone, wood, or even polished andesite.

Dual Targeting Modes

Switch easily between mob-only and mob + player mode to adapt your defense for survival or multiplayer gameplay.

Portable Design

Move your sentries anywhere without losing settings — perfect for players who redesign or relocate often.

Multiplayer Ready

Works flawlessly in Realms or local servers, maintaining stability for everyone in shared worlds.

No Experimental Settings Required

Fully functional on standard MCPE (1.21 + recommended). Stable, plug-and-play performance across all platforms.

Optimized Performance

Smooth gameplay even on mid-range devices — Android, iOS, Windows 10/11, Xbox, or Switch.

Performance Tip: Keep spacing between multiple sentries to maintain ideal FPS on smaller devices.

Take full advantage of the addon’s versatility:

• Blend sentries into walls, gardens, or gates for invisible protection.
• Layer defenses — ground sentries for mobs, higher ones for flying threats.
• Mark zones in multiplayer maps to avoid friendly activation.
• Experiment with themes: futuristic bases, castles, or hidden jungle outposts.

This addon encourages you to think like a designer and strategist at once.

The Sentry Blocks Addon isn’t just another defense mod — it’s a statement of smart building. It empowers you to create worlds that are both safe and stunning. No unnecessary clutter, no complex setups, just pure Minecraft creativity guarded by hidden intelligence.

With invisible power under every block, your base becomes more than a build — it becomes a living fortress that protects your imagination.
