Stealth Mechanics
by ThirtyFangs
Stealth Mechanics gives builders configurable rotating projectors and search lights that trigger custom actions once a player is spotted.
What it does
Stealth Mechanics lets a builder place rotating projectors and search lights and set them to react when a player is spotted. Once a player is caught in the beam, the projector starts following that player's movement, and a temporary message tells the player that they have been spotted. Actions are driven by a repeating command block and a tick function that checks for the spotted tag, so each projector can carry its own effect, such as a teleport to a prison location or a summoned zombie.
Each projector can be given a different response, for example teleporting a player who is caught by one projector to one place and a player caught by another, farther away, to another place. The distance parameter in the spotted check limits how far from a projector a caught player is affected. The mod is published for Fabric, Forge, NeoForge and Quilt, and the latest files cover 26.3. The server runs the detection and actions, while players may add the mod but do not need it to join. The license is All rights reserved, so the mod is not open source.
