Structural Safety

Protect structures and world-generation features without changing how Minecraft feels.

Structural Safety is a fully server-side protection system for Minecraft structures and world-generation features. Players remain in Survival Mode, while protected areas automatically control what they may break, place and interact with.

Allowed blocks still use normal Vanilla mining mechanics — including mining speed, tools, durability, enchantments, drops and events.

No client mod is required.

✨ What Structural Safety Does

When players enter a protected structure or feature, Structural Safety automatically applies the rules configured for that area.

Players can still:

• Fight mobs normally
• Loot chests and containers
• Break specifically allowed blocks using normal Vanilla mining
• Use tools, enchantments and durability normally
• Interact with permitted blocks
• Place approved temporary or permanent items
• Explore structures without their game mode being changed

At the same time, Structural Safety can prevent players and environmental effects from damaging important generated areas.

Everything can be configured live in-game through a server-side graphical menu.

Structures & World Features

Structural Safety can protect both Minecraft structures and world-generation features.

This includes areas such as:

• Villages
• Strongholds
• Trial Chambers
• Ancient Cities
• Woodland Mansions
• Pillager Outposts
• Nether Fortresses
• Bastion Remnants
• Ocean Monuments
• End Cities
• Desert and Jungle Temples
• Mineshafts
• Monster Rooms
• Modded structures
• Supported world-generation features

Feature support also allows generated areas that are not technically Minecraft structures to receive the same protection system.

For example, Vanilla Monster Rooms / Dungeon Spawners can be detected and protected.

⛏️ Vanilla-Style Mining Protection

Structural Safety does not switch players into Adventure Mode.

Instead, the server decides whether a block is allowed to be mined.

If a block is allowed, Minecraft handles the rest normally:

• Mining progress
• Correct tool checks
• Mining speed
• Tool durability
• Enchantments
• Block drops
• Break events
• Mod compatibility

This keeps protected areas much closer to normal Survival gameplay.

---

Individual Rules for Every Area

Every protected structure and feature can have its own block-breaking rules.

There are four rule modes:

Mode	Behavior
inherit	Uses the shared global breakable-block list
extend	Uses the shared list plus additional area-specific blocks
replace	Uses only the blocks configured specifically for that area
none	No block breaking is allowed

This means different locations can behave completely differently.

For example:

• Villages can allow crops and decorative blocks
• Dungeons can allow cobwebs
• Adventure-map areas can completely disable breaking
• Modded structures can have their own custom rules

Rules can be managed through commands or directly through the graphical menu.

---

Interaction & Placement Rules

Breaking blocks is only one part of the protection system.

Structural Safety can also control which blocks players may interact with and which items they may place.

Interactions

Allowed interactions can include:

• Containers
• Redstone components
• Brushable blocks
• Doors and mechanisms
• Other configured blocks

Temporary Blocks

Specific items can be placed temporarily inside protected areas.

Examples include:

• Torches
• Ladders
• Blocks used to escape dangerous situations

Temporary blocks are automatically removed after a configurable amount of time.

Permanent Placement

Specific items can also be allowed as permanent placements when needed.

All placement and interaction rules are configurable.

---

Environmental Protection

Protected areas can also be protected from environmental destruction.

Protection	Description
Explosions	Prevents TNT, Creepers and similar explosions from destroying protected blocks
Fire	Prevents fire and fire spread from damaging protected areas
Lava	Prevents flowing lava from entering protected regions

Each protection can be configured independently.

---

Structure & Feature Detection

Structural Safety automatically works with generated structures and supported features.

Detected feature regions are stored per dimension, allowing the protection system to remember generated areas across server restarts.

The mod also includes controlled scans for already-loaded chunks.

These scans are throttled and do not force additional chunks to generate or load, making the system suitable for larger servers and existing worlds.

---

ℹ️ Player Information

Players can use:

/structuralsafety info

The command automatically detects the protected structure or feature the player is currently standing inside.

It can display:

• Area name
• Area ID
• Whether it is a structure or feature
• Active break-rule mode
• Exactly which blocks may currently be broken
• Whether sneaking is required for specific actions
• Shared interaction rules
• Placement rules

An optional chat hint can also appear when entering a protected area.

The /structuralsafety info entry hint can be enabled or disabled separately.

---

Configurable Player Feedback

Server owners can customize how Structural Safety communicates with players.

Available feedback includes:

• Area entry messages
• Area exit messages
• Denied-action messages
• Protection sounds
• Escape hints
• Temporary-block timer feedback

This allows the system to remain subtle on Survival servers or provide more detailed guidance on adventure and RPG servers.

---

🖥️ Fully Server-Side Menu

Open the management interface with:

/structuralsafety menu

Structural Safety uses a Vanilla chest-based GUI, meaning the entire interface runs server-side.

No client mod is required.

The menu can manage:

• Structures
• World-generation features
• Break rules
• Block allowances
• Interaction rules
• Placement rules
• Player feedback
• Protection settings
• Diagnostics
• Administration tools

For normal administration, there is no need to manually edit configuration files.

---

Singleplayer Support

Structural Safety fully supports Minecraft's integrated singleplayer server.

Singleplayer world owners can configure the mod through its menu even when cheats are disabled.

The same management system therefore works for:

• Dedicated servers
• LAN worlds
• Singleplayer worlds
• Modpacks
• Adventure maps

---

Inspection & Preview Tools

Structural Safety includes administration tools for understanding exactly why an action is allowed or denied.

Live Inspection

/structuralsafety inspect

Inspection mode provides live information about:

• Protection lookups
• Block-breaking decisions
• Interaction decisions
• Placement decisions
• Active area rules

This is especially useful when configuring modded structures or troubleshooting large modpacks.

Protection Boundary Preview

/structuralsafety preview

Displays detected protection boundaries using Vanilla particles.

This makes it easy to verify that a structure or feature uses the expected protected region.

No client-side rendering mod is required.

---

Diagnostics

Structural Safety includes live diagnostic information for server administrators.

Diagnostics can report information about:

• Protection lookups
• Allowed actions
• Denied actions
• Structure and feature scans
• Temporary blocks
• Audit status
• Configuration health

These tools make large configurations and modpack compatibility easier to troubleshoot.

---

Audit Logging

Optional asynchronous audit logging can record relevant protection activity without blocking normal server processing.

Audit logs use automatic rotation to prevent a single log file from growing indefinitely.

This can be useful for:

• Public servers
• Modpack development
• Troubleshooting
• Finding configuration mistakes
• Investigating unexpected protection behavior

---

⚙️ Safe Configuration System

Structural Safety includes safeguards designed to reduce the risk of configuration mistakes.

Configuration reloads support:

• Validation before activation
• Safe rollback when a configuration is invalid
• Backups of rejected configurations
• Conservative configuration repair tools

Existing custom settings are preserved when compatible new defaults are introduced.

---

Built-In Presets

Structural Safety includes several predefined configuration styles that can be used as starting points.

Vanilla-Friendly

Designed to protect generated areas while keeping gameplay close to normal Survival.

Anti-Grief

Stronger protection intended for multiplayer servers.

Strict

More restrictive protection for servers where generated structures should remain largely untouched.

Adventure Map

Designed for controlled environments where players should interact with structures without modifying them freely.

Presets can be customized after applying them.

---

Permissions

Administration access can be separated into different permission categories.

Permissions are available for actions such as:

• Viewing information
• Managing protection
• Inspection
• Testing
• Diagnostics
• Auditing
• Escape functionality

This allows server owners to give moderators or administrators access only to the tools they actually need.

---

🚪 Safe Escape System

Players who become trapped inside protected areas can use:

/structuralsafety escape

The escape system searches for a safer location instead of simply disabling protection.

It is designed as a recovery tool rather than a fast-travel command.

Server owners can configure the related behavior and permissions.

---

Technical Test Mode

Structural Safety includes a dedicated technical test system for developers, modpack creators and advanced server administrators.

Technical test mode provides:

• Non-destructive startup self-tests
• Temporary in-memory structure test areas
• Temporary in-memory feature test areas
• Guided protection tests
• Breaking tests
• Placement tests
• Feedback tests
• Escape-system tests

Temporary test areas use the same protection engine as real structures and features.

Technical test mode is automatically enabled for development environments such as IntelliJ runs and disabled by default in packaged releases.

---

⚡ Performance

Structural Safety is designed around server-side operation.

Important systems include:

• Per-dimension feature-region storage
• Persistent temporary-block tracking
• Throttled scans
• No forced chunk generation during feature rescans
• No unnecessary loading of unloaded chunks
• Asynchronous rotating audit logs
• Server-side protection decisions

The client does not need to install Structural Safety.

---

Modded Content

Structural Safety is designed to work with modded Minecraft environments.

Modded structures can be detected and configured individually, allowing modpack creators to decide exactly which generated locations should receive protection.

Each protected area can use its own:

• Break-rule mode
• Additional allowed blocks
• Interaction rules
• Placement behavior
• Protection settings

This makes Structural Safety especially useful for modpacks, RPG servers, adventure servers and heavily modded Survival worlds.
