* This is the complete version of my "project" - https://sampforum.blast.hk/showthread.php?tid=521690
I've fixed various bugs, and also improved some stuff.
The code will now work as the aimbot works, It will ignore people surfing(since the aimbot then isn't accurate), and people in cars = Less false alerts.
* IMPORTANT: Please load the filterscript as the server starts( Don't use /rcon loadfs .... ), as It might cause lag issues when loaded while server is already up/on!

I've tested this with 7 players, and didn't have any false warnings. I suppose the code could support up to 20 - 50 players.. Should be Okay for A/D and other small servers.
Things we did while testing;
Used weapon switching, C-bugged / Rapid-fired,Slide-bugged,Used "runnies" weapons, to be sure the code won't fail in such ways.
