Description

Lightsense

One key shows where monsters can spawn. Red crosses where one can spawn right now, yellow crosses where one can spawn once night falls.

What it does

  • Press F7 (Controls > Lightsense) to cycle off, near (8 blocks), far (16) and wide (24).
  • A cross lies on every block where a monster could spawn: standing room for two blocks, on a block with a sturdy top.
  • Red: spawnable now. Yellow: safe now, but not at night.
  • The test is the game's own, per dimension: the block light limit and the highest sky-plus-block light a spawn is rolled against (0 to 7 in the Overworld, a flat 7 in the Nether). Light the yellow ones and the red ones with torches and the cave stays quiet.
  • Rescans twice a second; nothing is sent to or asked of the server.

Needs

  • Minecraft 26.3 (Fabric), or the other versions listed under Files
  • Fabric API on Fabric
  • Client side only
