This mod turns off hitboxes when you press F3 + B, so fights feel fair and more immersive. In vanilla Minecraft, that debug feature lets you see entity hitboxes, which can give an unfair edge in combat—especially if you’re using mods like Timeless and Classics Zero.
With this installed, you won’t be able to rely on hitboxes anymore. You’ll have to aim properly, stay aware, and actually play by skill.
There are two versions of the mod:
The client version is lightweight and only affects your game. It blocks F3 + B locally, but you can still remove the mod and join servers without any issues.
The “server + client” version is stricter and meant for server owners. If someone tries to use F3 + B more than twice, they’ll be automatically kicked.
Admin Commands (Server Version): Server administrators can selectively bypass the hitbox restriction for specific players without disabling it for everyone else.
/hitbox allow <player>— Grants permission to a player (or yourself) to use F3 + B hitboxes without warnings or kicks./hitbox deny <player>— Revokes the hitbox permission from a player.
Works great for PvP, tactical shooters, and more realistic modpacks. Install it if you want cleaner, fair fights.
