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