Where it goes
Is Custom Hitboxes required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Custom Hitboxes 3.0.0+26.3 need?
3.0.0+26.3. Change the file and its required mods may change too.
Install WalksyLib first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Custom Hitboxes add?
Custom Hitboxes!
This mod is a complete overhaul of minecraft's hitboxes, allowing you to customize them along with added functionalities, such as specific team colors per hitbox, or damage colors.
Features
Hitbox styles
Every style has a live preview in the menu, so you can see your changes as you make them.
- Lines: width, colour, and an optional gradient into a second colour towards the top.
- Fill: a filled hitbox with its own colour and optional gradient.
- Rainbow colours: any colour can be set to rainbow from the colour picker.
- Look vector: a line showing where the entity is looking, with adjustable length, colour and an optional arrow.
- Eye height: a thin box at the entity's eye level, outlined or filled.
Highlights
Recolour a hitbox while the entity is:
- Hurt: during its damage tick.
- Targeted: while your crosshair is on it.
- In range: while it's within your reach.
Hitbox vanishing (idea from pCrit)
Hide hitboxes when an entity gets within a set distance, to cut the clutter (like end crystal or player hitboxes) at the range you PvP at. Turn on Vanish Fade to have them fade out gradually instead of disappearing at once.
Per-entity styles
Add any entity on the Entities page to give it its own style. Turn on Only Listed Entities to draw hitboxes only for the entities you've added.
Team styles
Teams are shared across all WalksyLib mods. Put players in a team once, then turn on Apply Team Style in Custom Hitboxes to give that team's players their own hitbox style. This is great for teamfights.
General
- A keybind to toggle hitboxes on and off.
- Show hitboxes automatically when the game starts.
- Choose whether to show your own hitbox.
- Only show player hitboxes while they're gliding.
