Player Move Detector
by Leefy
Player Move Detector shows a green or red mark above a player's name, depending on whether that player has moved.
What it does
The mod checks whether each player has moved and shows a green mark above the name of a player who is standing still, or a red mark when the player is moving. Pressing the hotkey again removes the mark. Fabric is the only loader with files, and they target 1.21 alone, with 1.1.0 as the latest build from 2025-08-29. Only the client needs the mod, and Cloth Config API, Fabric API and Mod Menu must be installed alongside it.
Key features
Movement mark
A marker above a player's name shows green when that player is standing still and red when the player moves.
Hotkey toggle
A key binding turns the movement mark on and off, so it can be hidden when not needed.
Name display
The mark appears directly above the name tag, so movement can be read at a glance in a crowd.
