Danger Sense

Danger Sense is a client-side Fabric mod that highlights nearby dangerous blocks with an animated, world-border style red overlay, so you can spot hazards at a glance even from far away. It does not change gameplay, add items, or reveal anything hidden inside or behind other blocks. It only draws attention to dangers that are already visible, but easy to miss.

What it highlights

Every category can be turned on or off individually.

How it works

The mod scans the blocks around you (radius configurable, 4 to 32 blocks) and draws a glowing red forcefield grid, using the same texture and scrolling animation as the vanilla world border, over each detected danger:

• Overlays match the block's real outline shape: a thin strip for armed tripwire, a chest-shaped box for trapped chests, a full cube for powder snow.
• Highlights fade in smoothly as you approach and fade out as you walk away.
• Touching blocks of the same type merge into one outlined shape, so a powder snow field reads as a single blob.
• Broken or replaced blocks lose their highlight instantly.
• The overlay is emissive, so it stays visible at night and in caves.

Controls and settings

• Press V (rebindable) to toggle the overlay in-game.
• With Mod Menu installed, open Mods > Danger Sense to configure: master toggle, scan radius, overlay opacity, animation speed, and per-danger toggles.
• Settings are stored in config/dangersense.json.

Requirements

• Minecraft 1.21.11 with Fabric Loader
• Fabric API
• Mod Menu (optional, for the settings screen)

Danger Sense is client-side only and works in singleplayer and on any server, since it only uses information the server already sends to your client (trapped chests, tripwire and the rest are all technically visible to the naked eye).
