CustomBarrier

A Fabric mod that adds a configurable barrier block with selective player pass-through, custom particle effects, and optional opaque rendering.

Features

• Three pass-through modes configurable per-block via an in-game GUI:
  • TAG — player must have specific scoreboard tags (comma-separated for multiple)
  • PLAYER — player's display name must match (comma-separated for multiple)
  • PREDICATE — this mode will use minecraft vanilla predicate system
• Ethereal Effect — a status effect granted on successful check that allows temporary passthrough
• Custom particles — any particle type ID configurable per block
• Opaque toggle — renders as an End Gateway when enabled; invisible otherwise
• Waterloggable
• Configuration GUI — creative-level-2-op players right-click (offhand empty, not holding the barrier) to open
• No collision until the player's check passes

Usage

1. Place the Custom Barrier block
2. Right-click it as a creative op (offhand empty, not holding the barrier item)
3. Set the particle ID, check string, mode, and opaque toggle in the GUI
4. Press Save — settings persist via BlockEntity NBT
