Third person camera aim

hey guys i have a third person character and i want to make him pick up objects and throw them! But the camera is rotating fast and the object is thrown in a "random" point and not where i want! so i want to aim first and then throw it in the camera direction! This is my script but whatever i am trying in the aim void doesnt seem to work! (I want to access my main camera via this script if possible and not have multiple scripts) Pleas help me ...i am stuck in this part for a week!
