Create Bugfix: Schematic Patch

## This mod has been discontinued and will no longer receive updates or support. Please visit https://modrinth.com/mod/createschematicchecker to find a similar mod. ### Overview

This mod fixes a critical schematic item exploit in the Create mod for Minecraft 1. 21+. Please note: when using the mod for the first time on your server (mod_version ≥1. 1), execute the command `/schematic-config reload` to initialize the mod configuration.

### Original Issue

Create's schematics could store blocks/items with illegal components, allowing players to obtain unobtainable survival items.

### Fix Features

Anomaly Detection: Scans uploaded schematics in real-time Data Sanitization: Automatically removes illegal components/blacklisted blocks Alert Logging: Outputs server warning when player uploaded anomaly schematic Auto-Archiving: Backups anomalous schematics at:/schematics/anomaly/playername/schematic.nbt #### For mod_version<1. 1. 3 Configurable: Blacklist management via `schematicsfix-common.toml` Advanced Configuration Feature: You can define the schematic NBT detection logic using JSON in `schematicsfix.jsonl`. However, please note that this feature is still experimental. Unless you know what you are doing, do not modify the default advanced configuration. #### For mod_version≥1. 1. 3 Configurable:Define NBT filter rules freely through `schematicsfix.yaml` ### Admin Benefits

1. Real-time exploit blocking 2. Automatic evidence preservation 3. Customizable filter rules 4. Zero manual review for legitimate uploads

### Configuration File Format (mod_version≥1. 1. 3) #### Configuration File Location: config/schematicsfix.yaml

#### Basic Structure: ``` version: "1. 0" rules: - name: "rule_name" target_path: "target_path" conditions: - condition_list cleanup_actions: - cleanup_action_list ``` #### Rule Fields: - name: Unique identifier for the rule, used for logging and command display - target_path: Target path to search for in NBT data, supports wildcards - conditions: List of conditions that must all be satisfied to trigger cleanup - cleanup_actions: List of cleanup actions to execute when conditions are met

#### Path Syntax: - Normal path: Use dots to separate, e.g., "blocks.nbt.id" - Wildcard: Use [ ] to match all array elements Example: "blocks[ ].nbt" matches nbt fields in all blocks arrays Example: "messages[ ]" matches all elements in messages array - Specific index: Use to match specific array index Example: "messages" matches the first element in messages array

#### Condition Types: ``` field_equals - Field value equals type: "field_equals" path: "field_path" value: expected_value ``` ``` field_not_equals - Field value not equals type: "field_not_equals" path: "field_path" value: expected_value ``` ``` field_exists - Field exists type: "field_exists" path: "field_path" ``` ``` string_contains - String contains type: "string_contains" path: "field_path" value: "string_to_find" ``` #### Cleanup Action Types: ``` conditional_remove - Conditional removal type: "conditional_remove" target_path: "target_field_path" condition: removal_condition (optional) remove_strategy: "field_only" (only removes field value) ``` ``` path_remove - Path removal type: "path_remove" target_path: "target_path" remove_strategy: "entire_object" (removes entire object) ``` ``` nested_string_remove - Nested string cleanup type: "nested_string_remove" target_path: "target_path" condition: trigger_condition (optional) remove_pattern: "regex_pattern" remove_strategy: "regex_replace" ``` #### Complete Examples:

Example 1: Clean specific fields of valve handles Rule name: valve_handle_capacity_cleanup Target path: blocks[ ].nbt Condition: id field equals "create:valve_handle" Action1: If Network. Capacity not equals 256. 0, remove this field Action2: If Speed not equals 32. 0, remove this field

Example 2: Clean container data from clipboards Rule name: clipboard_container_cleanup Target path: blocks[ ].nbt Condition: id field equals "create:clipboard" Action: Remove Item.components.minecraft:container path

Example 3: Clean click events from signs Rule name: sign_clickevent_cleanup Target path: blocks[ ].nbt Condition: id field equals "minecraft:sign" Action: Search for strings containing "clickEvent" in front_text.messages[], use regex to remove clickEvent objects

#### Configuration Example Code: ``` version: "1. 0" rules: - name: "valve_handle_capacity_cleanup" target_path: "blocks[*].nbt" conditions: - type: "field_equals" path: "id" value: "create:valve_handle" cleanup_actions: - type: "conditional_remove" target_path: "Network. Capacity" condition: type: "field_not_equals" path: "Network. Capacity" value: 256. 0 remove_strategy: "field_only"
