Description

Create Bugfix: Clipboard Patch (English Version)

Introduction
This mod fixes a critical exploit in Create Mod's clipboard item for Minecraft 1.21+. Maliciously modified clipboards with illegal data components could trigger item duplication. The patch automatically sanitizes component data to ensure gameplay security.

Technical Mechanism

  1. Event Monitoring: Hooks into ItemTossEvent (player item-drop event)
  2. Item Identification: Detects if dropped item is create:clipboard
  3. Component Whitelisting: Only preserves:
    • create:clipboard_pages (page content)
    • create:clipboard_type (clipboard type)
  4. Illegal Component Handling:
    • Generates clean clipboard instance
    • Migrates whitelisted valid data
    • Auto-replaces dropped item
  5. Exploit Prevention: Blocks item duplication via container or other illegal components

Fix Impact

  • Permanently patches item duplication exploits
  • Maintains normal clipboard functionality (text/icons preserved)
  • Compatible with all Create Mod versions
