Ht1box
by kazut0
Ht1box changes how entity hitboxes are drawn on the Fabric client, coloring them by player name and by entity type, and fading the entity a player is aiming at.
What it does
Ht1box is a client-side Fabric mod for the 1.21.8 – 1.21.11 range. It draws hitboxes with clearer colors: player hitboxes take the color of the player's display name, and the tab list can fall back to scoreboard team colors. Individual entity types can be given their own hitbox colors in the settings. The mod also removes the blue look-vector line and the eye height indicator line that vanilla hitbox display can show.
When an entity sits within attack range and is being aimed at, its hitbox becomes semi-transparent, at 80 percent, so the target stays readable without blocking the view. The fade can be switched off in the config. Settings are opened through Mod Menu and are built on the YACL configuration library, which is required. The author notes that some options need files edited by hand. Files are published for 1.21.8 and 1.21.11, with the latest Fabric build covering 1.21.11 and dated 2026-04-20. The code is licensed under the Apache License 2.0, and the project is not open source.

Ht1box covers 1.21.8 – 1.21.11 and is not open source, but it adds name colors, entity colors and the targeted fade.
