About this project

What does Structures Tweaker add?

Structures Tweaker

Take control of how structures work in your world. Whether you're building an adventure map, running a server, or just want to customize your gameplay experience, Structures Tweaker gives you the tools to configure structure behavior exactly how you want it.

What This Mod Does

Structures Tweaker lets you customize the rules and restrictions for any structure in Minecraft. Want to make dungeons where players can't break blocks? Need a trial chamber where elytra flight is disabled? Looking to create protected spawn areas or custom challenge zones? This mod has you covered.

Key Features

Block Protection

  • Control whether players can break or place blocks in structures
  • Protect only original structure blocks or everything within the boundary
  • Configure block interaction rules (buttons, levers, chests, etc.)
  • Set up whitelists and blacklists for specific block interactions

Movement Restrictions

  • Disable elytra flight in specific structures
  • Block ender pearl usage to prevent skipping content
  • Restrict creative flight for adventure maps
  • Control riptide trident usage
  • Manage all ender-based teleportation (pearls, chorus fruit)

Gameplay Control

  • Enable or disable PVP in structures
  • Control mob spawning rates
  • Manage explosion damage and fire spread
  • Configure item pickup rules
  • Create item use blacklists and whitelists

Flexible Configuration

  • Per-structure configuration - each structure type can have its own rules
  • Inheritance system for easy management of similar structures
  • Global defaults with structure-specific overrides
  • Support for modded structures
  • JSON-based configs that are easy to edit

Perfect For

Adventure Map Creators: Design challenges where players must follow specific rules. Create dungeons that can't be cheesed with ender pearls or trial chambers that require legitimate completion.

Server Admins: Protect spawn structures, create safe zones, or design special PVP arenas with custom rules. Keep your builds intact while still allowing interaction where needed.

Pack Makers: Add progression gates to structures, create themed challenges, or balance gameplay by restricting certain items and abilities in specific locations.

Regular Players: Customize your single-player experience. Make structures more challenging by disabling flight or protect your favorite village from accidental damage.

How It Works

The mod automatically detects when players enter structures and applies the configured rules. Each structure type can have its own configuration file, or you can use the global config to set defaults for all structures. The system is highly flexible - start with broad rules and add exceptions as needed.

Configuration files are stored in config/structures_tweaker/ and use a simple JSON format. The mod includes helpful commands for testing and debugging your setups.
