What it does
With HitBox the reach is honest — the target isn't. The cheat inflates opponents' hitboxes on the cheater's screen, so a swing that would have passed by a shoulder counts as a hit. A real player hitbox is 0.6 blocks wide; with the cheat it's noticeably wider, and missing someone who strafes, jumps or peeks around a block becomes nearly impossible.
It pays off in duels full of fast strafes, in team fights where targets flicker through the crosshair, and against players on elytra. To an onlooker the cheater just looks accurate, which makes HitBox harder to spot by eye than blatant Reach.
How to spot it
- In spectator mode the crosshair passes beside the opponent, yet the hit still registers
- Almost no misses against strafing and jumping targets, despite otherwise sloppy aim
- Hits an opponent who's only partly visible around a block or corner
- Hit distance is normal — it's the accuracy that's suspicious
How it gets caught
The server knows where the player was looking: the rotation arrives in the packets. The anticheat rebuilds the target's position as the client saw it and casts a ray from the eyes in that direction. If the ray misses the real hitbox by more than the tolerance, the hit landed on an inflated box. It's the same raytrace that catches Reach, only the angle breaks instead of the length.
The tolerance matters: the client draws opponents with interpolation, packets arrive late, and an honest hit on the very edge of a hitbox can look like a miss. Evidence is a pattern of hits outside the box, not one frame.
