Full Hopper Glow
by ha4zyk
Full Hopper Glow outlines hoppers in red when their inventory slots are full, so players can spot them while looking around a base.
What it does
A hopper that has every slot holding at least one item gets a red outline when a player looks at it nearby. The outline shows the state of the hopper without opening its screen, which helps in storage rooms and item-sorting lines where a jammed hopper would otherwise go unnoticed. A toggle key switches the glow on and off, and the binding sits in the Controls menu under Full Hopper Glow, Hopper Lock Glow.
The mod is a Forge utility with a Decoration and Transportation tag. It runs on client and server: the outline is synced by the server, so it works in single-player and in multiplayer, but every player who wants to see it has to have the mod installed. Files are published for Forge only, for six game versions 1.20.1 – 1.20.6, with 1.0.0 for 1.20.6 as the latest file. The mod is not open source and is released under All rights reserved.
Key features
Red outline for full hoppers
A hopper with every inventory slot holding at least one item is outlined in red when it is in view.
Server-synced highlighting
The outline is synced from the server, so the same hoppers glow for every player in single-player or multiplayer.
Toggle key
A key binding turns the glow off when it is not wanted and back on when needed.
Lightweight addition
The mod adds no new blocks or items and changes only how hoppers are drawn.
