Hitbox+ turns the game's F3+B debug hitboxes into a customizable PvP aid, as a native mod for Horizon.
- In-reach colour: a hitbox takes your chosen colour while your crosshair is on it within hitting distance: 3 blocks for swords, axes, maces and fists, 4.5 blocks for spears in survival (6.5 in creative).
- 11 reach colours, from bright green to a smooth rainbow, and hitbox styles (white, cyan, yellow, red, rainbow).
- Three thicknesses: thin, default or thick lines.
- Eye rays: optional looking-direction lines and eye-level markers.
- Sprint HUD: a sprint indicator in the screen corner you pick.
Press H to show or hide hitboxes. Colours, thickness and the HUD's corner are in Options > Mods > Hitbox+.
Native code
A native mod is Rust code that the launcher compiles into a game of its own, the Native mods instance. It is not sandboxed: it can do anything you can on this computer. The launcher builds it only after a warning that names it, and a reviewer read its source before it was listed. Read the source yourself before you build it. How native mods work
