Aim Assist

So, I found this aim assist on the site...I was just wondering how it would be used...I know it can be used in a GSC script, but where would I put the file, how would I make it, etc? Would I use an MW2 file that already exists?

To be clear about what I want, I'm looking for something like Roccat (kone driver-COD4). If this isn't what I'm looking for, please redirect me to something else.

I simply want to know how to install it...

aim_autoaim_enabled "1"
aim_autoaim_lerp "100"
aim_lockon_debug "1" //Not required, just the ESP thingy
aim_lockon_enabled "1"
aim_lockon_strength "1"
aim_lockon_deflection "0.05"

Secondly, I would like to know how good of an aim assist this is....would it be easy to use for quickscoping and no scoping? That's mainly what I'd use it for. If you can, compare it to COD4 Roccat (Kone Driver)...I loved that aim assist, if you could, it would help me visualize how it feels. Is this an ESP as well? Will it show my players behind walls like, put a dot on them or something? I hope you can help..



And thanks!
