Plugin ElectricFence

ElectricFence, Electrified Fences with Redstone

ElectricFence is a Bukkit and Spigot plugin that turns selected fences into dangerous security barriers on a Minecraft server. When a fence receives redstone power, or has redstone running alongside it, players and nearby living entities can be shocked when they touch or approach it.

Server owners can configure damage, shock radius, affected mobs and players, supported wood or iron fences, warning messages, and lightning effects. An operator or the ElectricFence.bypass permission prevents damage. At BoxToPlay, this lightweight feature suits survival bases, traps, arenas, and themed defenses, with listed support for Minecraft 1.12.
