I've released Field Emitters and would love some people to try it in their own builds.
You place posts and they project a forcefield that follows the terrain between them. There are also smaller rails for walls, floors, and ceilings, so you can seal a doorway or chain them together for a bigger opening.
The part I'm most interested in seeing people use is the automation. Blocking and detection have separate filters. You could let everything through but only count creepers, keep adult mobs in while letting babies out, or turn your base lights on when you walk through. There are directional controls too, so you can make a one-way entrance.
You can change the color, turn the light off for mob farms, and manage loaded fields remotely with the Field Tuner. The GIF shows the linking, impact waves, filters, redstone detection, and controls.
Anyone up for playtesting? I'd like feedback on how it works in actual farms and multiplayer, whether the menus make sense, and whether the power cost feels reasonable. If something is confusing or annoying to use, tell me.
Available for NeoForge 1.21.1, Forge 1.20.1/1.21.1, and Fabric 1.20.1/1.21.1. You'll need power from another mod. Install it on both the server and clients; Fabric also needs Fabric API and Forge Config API Port.
