Aimbot Detector/OnPlayerTakeDamage

Hi,



I'm currently creating an RP server, an idea came on my mind,



If admin is spectating Player A,

Player A is fighting Player B, Player A shoots at Player B > I want an marker/pickup to create when the Player has fired that bullet.



If anyone can script this with function OnPlayerTakeDamage, I'd really appriciate it +rep from me.

Thanks.
