HitBox+

HitBox+ is a client-side Fabric mod for customizing Minecraft entity hitbox colors.

Screenshots

Player rules let you tune self, neutral, friend, and enemy hitboxes separately.

Player hitbox configuration

Entity overrides let you enable custom styling for individual entity ids.

Entity hitbox overrides

Group defaults cover broad categories such as passive mobs, hostile mobs, bosses, projectiles, vehicles, and miscellaneous entities.

Group hitbox defaults

The style editor controls color, visibility, line thickness, pattern, eye line, and look direction for each rule.

Hitbox style editor

Customize the default hitbox style used for entities without a more specific rule.
Configure separate styles for self, neutral players, friends, and enemies.
Use Minecraft team colors for neutral players when enabled.
Set broad defaults for passive mobs, hostile mobs, bosses, projectiles, effects, vehicles, and miscellaneous entities.
Add per-entity overrides for any registered entity id.
Choose full or dotted hitbox lines, line thickness, eye line visibility, and look direction visibility.

HitBox+ uses YACL for its config screen and integrates with Mod Menu when it is installed. The config file is stored at:

config/hitboxplus.json5

The config screen includes active entity overrides, an entity picker, and a custom entity id field for ids such as minecraft:zombie.

HitBox+ adds client-side commands for managing player relation lists:

/hitboxplus {friend|enemy} {add|remove} <player>
/hitboxplus {friend|enemy} list

Player name suggestions are provided from online players and existing configured names.

Use Minecraft's pick-block control while targeting a player to cycle that player through:

friend -> enemy -> neutral

HitBox+ saves the change immediately and shows a chat confirmation.
