CSB Bhop Script Detection

v1.0.0 0 downloads Daemon666 Last updated: Jul 15, 2026

Flags scripted bunnyhopping from a run of frame-perfect jumps that no human can repeat by hand.

CSB Bhop Script Detection separates a good hopper from a scripter by looking at when the jump happens, not how far it goes. In PlayerPreThink it watches the FL_ONGROUND flag and the +jump button: a bunnyhop script re-presses jump on the very first ground frame every single time, which a human simply cannot do. A long run of these frame-perfect jumps is logged and optionally punished.

How it works

  • Tracks the ground/air transition each frame and counts frames spent on the ground.
  • Only the rising edge of +jump is counted, so holding jump isn't misread.
  • A jump on ground-frame 0 or 1 is "perfect"; a normal jump resets the streak.
  • csb_bhop_perfect consecutive perfect jumps triggers a log line and, if csb_bhop_action 1, a kick.
