Detecting aimbot using traces?

Garry's Mod coding
#1 

Aimbot_Detection_Time = 30 -- In seconds, how long will it take to alert admins after being detected? (like if they stop aimbotting this wont tell admins)
Aimbot_Staff = { "moderator", "admin", "superadmin" }

hook.Add( "PlayerInitialSpawn", "Aimbot_Detection_Unit", function( ply )
	ply._suspect = false
	ply._hitbox = false
	timer.Create( "Aimbot_Detecting", 0.01, 0, function()
		local victim = ply:GetEyeTrace().Entity
		local hitbox = ply:GetEyeTrace().HitGroup

		if IsValid( victim ) and ( victim:IsPlayer() or victim:IsBot() ) then
			if not ply._hitbox then
				print( hitbox .. "" .. victim:Nick() )
				ply._hitbox = hitbox
				timer.Create( "HitBox_Detection", Aimbot_Detection_Time/2, 1, function()
					if ply._hitbox == hitbox then
						ply._suspect = true
						print( ply:Nick().." Might be hitbox hacking.." )
					end
				end )
			end
		end

		if ply._suspect then
			ply._eyeangles = ply:EyeAngles()
			if victim:IsPlayer() then
				timer.Create( "Aimbot_Detection", 1, 0, function()
					if ply._eyeangles != ply:EyeAngles() then
						if victim:IsPlayer() then
							timer.Remove( "Aimbot_Detection" )
							timer.Create( "Aimbot_Happening", 1, Aimbot_Detection_Time/2, function()
								if ply._eyeangles != ply:EyeAngles() then
									ply._aimbot_detected = ply._aimbot_detected + 1

									if ply._aimbot_detected >= Aimbot_Detection_Time/2 then
										for k,v in pairs( player.GetAll() ) do
											if table.HasValue( Aimbot_Staff, v:GetUserGroup() ) then
												v:PrintMessage( HUD_PRINTTALK, "Anti-Aimbot" .. ply:Nick() .. " Has detections of Aimbot, please spectate." )
											end
										end
										ply._suspect = false
										ply._hitbox = false
									end
								end 
							end )
						else
							ply._suspect = false
							ply._hitbox = false
							timer.Remove( "Aimbot_Detection" )
						end
					end
				end )
			end
		end
	end )
end )

I am just detecting if someone MIGHT be aimbotting then telling admins?
But its not working? Anyone know?

(addon works etc, just detection is not working?)

Using named timers is not going to work when you want 1 timer per player. Think about. Player 1 joins, your PlayerInitialSpawn hook is called and creates a timer called Aimbot_Detecting. Player 2 joins, your PlayerInitialSpawn hook is called, and creates a new (overwrites) timer called Aimbot_Detecting. You need a unique name for your timers, or use timer.Simple

#3

Also, this detection method is extremely inaccurate.

#4

Mother of nesting

#5

Can you give me a tip to fix up my code? because people are using a new hack engine that bypasses cac so… im having trouble detecting aimbot.

#6

The cheats that are bypassing CAC aren’t going to have an easy detection method like that. There are some people currently working on a solution, though.

#7

Just cache their angles with

CUserCmd:GetViewAngles and when they get a kill check if they snapped over ~45 degrees in a single tick.

#8

This is really inaccurate on low tick servers and will net alot of false positives.

#9

I was just giving an idea how to make a simple aimbot detection. Obviously it isn’t going to be perfect, but no aimbot detection method is 100% accurate.

#10

Your script is not good because you are creating a timer of 100Hz, per players !
The method you are describing here is not accurate enough.
Look at how csgo works :

  • VAC is scanning running tasks, scanning if variables are being edited illegaly, and if a dll is being injected ;
  • CSGO’s overwatch is a replay of a .dem, and players juge if they are watching a cheater aimboting.

Conclusion :
The best option is to give your admins a spectating feature (which already exist in many admin addons), and give your players a “Report a player” menu.
