Block Scanner and Replace

A Minecraft modification for Forge that provides players with powerful tools for working with blocks from various mods. With this tool, you can effectively maintain your worlds and simplify transitions between different modifications.

Areas of Application

Use this modification in situations when you need:

• Remove a specific mod from an existing world without causing damage
• Upgrade your save to a new Minecraft version
• Fix errors that occur after content updates

Functionality

Block Scanning: Search for elements added by various modifications around the character or in specified regions.

Automatic Replacement: Customizable profiles for replacing certain modded blocks with others or standard game objects.

Property Preservation: During all manipulations, blocks remain in their original orientation.

Safe NBT Data Transfer: Inventory data and other container information is copied to replacement objects without loss.

Area Operations: Processing entire chunks or large territories using individual commands.

Registry Management: Identification of all modified objects in your current installation.

Command System

Management is conducted through /blockscanner or the shortened version /bscan.

Core Commands

• /bscan scan [radius] — Search for modified blocks nearby
• /bscan replace [radius] — Replace specific materials
• /bscan reload — Reload configuration files
• /bscan addblock — Create new replacement rule
• /bscan listscanned — List of found mod-related objects
• /bscan generateconfig — Generate recommended configuration set

Area Operations

• /bscan activate [radius] — Start block replacement in area
• /bscan processall — Process all loaded map sections
• /bscan replacechunk — Replace objects in specific chunk
• /bscan status — Check replacement operation status

Map Work

• /bscan scanmap [render distance] — Analyze rectangular zone
• /bscan replacemap [render distance] — Replace objects in map area
• /bscan stopmap — Stop active scanning process

Continuous Scanning Mode

• /bscan autoscan on|off — Automatic analysis around players
• /bscan autoscan status — Check automatic mode status

Mod Registry Management

• /bscan registryscan — Scan and save all existing modded registry entries
• /bscan listmods — List of mods with registry elements
• /bscan listitems [mod_id] — Modified items listing
• /bscan listblocks [mod_id] — Block modifications listing

Configuration

BlockScanner configuration is located in the config/blockscanner/ directory:

• block_replacements.json — Main replacement rules file
• suggested_replacements.json — Automatically generated suggestions
• modded_blocks.yml — List of discovered non-standard materials
• modded_items.yml — Search for standardized objects

Replacement Format

Configuration uses JSON system:

{
  "modid:block_name": "minecraft:replacement_block",
  "anothermod:some_block": "minecraft:stone",
  "problematic:machine_block": "minecraft:furnace"
}

Automatic Replacement Process

When block replacement is activated, the following occurs:

• Preservation of block spatial placement
• Block states remain identical
• Copying of complex data when possible

Handling Problematic Scenarios

Recovering Missing Components

Scenario for replacing conflicting mods includes:

1. /bscan registryscan — Analysis of available objects
2. /bscan scan 128 — Search for modified materials near character
3. /bscan generateconfig — Generate recommended rules
4. Adjust suggested_replacements.json
5. Transfer content to block_replacements.json
6. /bscan reload — Apply updated parameters
7. /bscan activate 128 — Execute preservation process

Processing Large Maps and Servers

Using map commands ensures processing of extensive territories:

/bscan replacemap -1000 -1000 1000 1000 256

This command initiates comprehensive work on the current game world area.

Performance Considerations

• Large-scale replacements may require significant time
• Multi-threaded computations are used for efficiency
• Recommended to increase computing resource optimization for extensive operations

Compatibility

• Support for major modification platforms
• Functions in single-player mode and on servers
• Works alongside other content packs
