7msg Smooth Block Outline
7msg Smooth Block Outline highlights the block a player is looking at with a customizable outline, and the outline can fade in and out smoothly.
What it does
The outline is drawn around whichever block sits under the crosshair. Its color, which is set by red, green, blue and alpha values, and its line width can be changed, and a smooth slide fade animation plays as the target changes. The effect is confined to the player's own screen, so nothing changes for other players or on a server.
Smoothing can be switched on or off, and a speed slider controls how quickly the outline moves between blocks when smoothing is enabled. Settings are adjusted in the in-game options menu, and ModMenu provides access to that menu. The mod is built for Fabric, and its files cover one game version, 1.21.11.
The mod is client-side only, so only the player's client needs it and a server can run without it. Its files are published for Fabric alone, for 1.21.11. The code is released under All rights reserved and is not open source.
