This is a macro that I made in autohotkey and compiled as an executable. It works very well in 100tick servers. I haven't tested 33tick or 66tick servers though. It does NOT inject into the game and will always be 100% VAC PROOF

How to use it: Hold the spacebar down and hop!
_____________________________
okay found the scriptfile:
$SPACE::

if GetKeyState("SPACE","P")
Loop
{
if not GetKeyState("SPACE","P")
break
SetKeyDelay, 10
SendEvent, {SPACE}
Process, Priority,, High
}

so yes, it's safe for 100%

just download the exe and run it. then press space and hold it down and then happy bhop
works good on fast computers
