What are these Minecraft red lasers?
Posted On: July 8, 2023

These just appeared. What's going on?!.


They seem to follow me around, but appear patchily. What have I done?


Question from user fredley at stackexchange.


Answer:

They are marking locations where hostile mobs can spawn.


It is a feature of Not Enough Items (NEI) and the default key (configurable) to toggle this on and off is F7.
