About

Description

The night comes alive. When the sun goes down, fireflies come out over swamps, meadows and forests, glow worms light up the ceilings of dark caves, and now and then a will-o'-wisp drifts between the trees.

  • Fireflies blink in slow loops, low over the grass and the water. More in swamps and flower meadows, pink in cherry groves, amber in jungles. Fewer in the rain, none in the cold or the desert.
  • Glow worms hang from cave ceilings where no daylight reaches, breathing softly. A lush cave turns into a starry sky.
  • Will-o'-wisps are rare: blue lights in dark forests and swamps, cyan in the Soul Sand Valley. Walk up to one and it slips away.
  • Modded biomes work too: a biome called marsh, bayou, bog or fen gets its fireflies (tested with Biomes O' Plenty).
  • Light: only small particles close to you, and they fade out before they reach your face.

Options

Edit config/vitral_fireflies.properties (written the first time the game opens):

  • density: how many lights, from 0 to 3
  • fireflies, glowworms, wisps: turn each one on or off

Versions

Minecraft 26.3 and 26.2 (Fabric, needs Fabric API), 26.2 and 1.21.1 (NeoForge). Every version is tested in game.

Client-side

Nothing to install on the server. Works on any server, in single player and on Realms. No block, item or particle type is added: the lights are made on your screen only.

For modpack makers

Feel free to include Fireflies & Wisps in any modpack, no need to ask. It adds nothing to worlds or servers, so it is safe to add or remove at any time.

Made by an indie dev with help from AI tools; every version is tested in game.
