Smart doors — live showcase
Hostile mobs stop while villagers pass, with impact waves spreading across connected rails. Watch the full smart-door and tripwire showcase: https://youtu.be/_XEWAr7P7vQ
Linked posts
Two emitter posts project one field between them. The energy cube feeding the near post powers the whole link.
Posts at night
The same two posts after dark: the field glows cyan and the energy channels light the posts.
Perimeter overview
Four posts enclose a stepped hillside by day. The field climbs the stairs between them.
Perimeter at night
The hillside perimeter after dark in the violet preset, seen from inside beside the near post.
Blocking at night
A zombie held inside the lit violet perimeter at midnight. The default rule blocks hostile mobs and lets the owner pass.
Rails
Field Rails seal a doorway, a vertical shaft and a walkway. The redstone lamp beside the door lights on each detection pulse.
Blocking filters
The Blocking tab: category toggles, age and owner rules, entity type, item, UUID and tag fields, and the six movement directions.
Detection output
The Detection tab: pulse or steady signal, per-stack or per-item counting, and the same category and direction filters as blocking.
Field Manager
The Field Manager lists every loaded field in the dimension with its emitter count and running state. The tuner opens any of them remotely.
Emitter recipe
A Field Emitter in the crafting table: copper, amethyst and copper on top, glass around a block of redstone, iron along the bottom.
Field Emitters
Terrain-following forcefields with filters, detection output and a handheld tuner.
The hardware
The Field Tuner, with the emitter post, rail panel and tuner side by side.
Posts link, the field follows
Posts up to 20 blocks apart link into a five-block-high field that climbs the terrain.
The perimeter at night
The same hillside perimeter after dark.
Seal the openings
Rails mount on any block face and face another rail up to 20 blocks away.
Decide what gets through
Category, age, type, item, UUID, tag and direction rules for each link. The owner can be exempt.
Know what crossed
One redstone pulse per crossing or a steady signal while touched, with per-stack or per-item counting.
