ServerSide aimbot & wallhack

Hi, I want to know how to change where a client looks from server side to be able to make an aimbot.
I found addresses for it but whenever I change values it switch back to normal ones. (unwritable?)
If i know how to change where a client look the rest shouldn't be so hard.

I already know how to enable no recoil from serverside.

Serverside Wallhack is the real problem to me.. any hints or suggestions would be greatly appreciated.

The idea is: I want to make killstreaks rewards to clients
20 kills => no recoil, 30 kills => wh, 40 kills => aimbot for 30 seconds. Like this.
BTW, I use IW5M.. C#.. InfinityScript.. shhhh

Well I know that InfinityScript can change the RecoilScale (Thus making No-Recoil) and has the Chopper Boxes as an ESP so you can look into that.
An aimbot...well that'll be much more complicated. It might very well be possible (As you can change a client's view angles) but you'll need to be a C# expert.
