About this project

What does Mob Spawn Indicator add?

Mob Spawn Indicator highlights valid mob spawn floors in your vicinity with color-coded overlays. It uses vanilla spawn rules, so it works on any server without needing to be installed server-side.

Available for NeoForge (Minecraft 1.21 - 1.21.11, 26.1) and Fabric (Minecraft 1.21 - 1.21.11, 26.1).

Features

  • Color-coded overlays on valid spawn floors: red (danger), yellow (warn), green (safe)
  • Configurable render distance, opacity, and which colors to display
  • Settings GUI accessible from the mods screen (or Mod Menu on Fabric) and via commands
  • Client-side only - works on vanilla servers, SMPs, and modded servers

Commands

  • /msi settings - open the settings GUI
  • /msi toggle - toggle the overlay on/off
  • /msi on / /msi off - enable or disable the overlay
  • /msi reset - reset all settings to defaults

Configuration

Default keybind: J (toggle overlay)

Config file: config/msi-common.toml (same on both loaders)

Option Default Description
renderRadius 16 Render distance in blocks (4–64)
overlayOpacity 0.5 Overlay transparency (0.05–1.0)
showDanger true Show red overlay (valid spawn, no space for mobs)
showWarning true Show yellow overlay (valid spawn, 1 block space)
showSafe false Show green overlay (valid spawn, 2+ block space)

Notes

  • Uses vanilla Minecraft spawn rules: slabs, stairs, trapdoors, glass, and leaves are correctly excluded as non-spawnable
  • Overlays update every 5 ticks
  • Works in singleplayer, LAN, and multiplayer
