Alright so in my game the player can pick up items and drop them with the left click mouse button. Please any help would be nice code, video link ect.
well i would say just let a script attach the object to your camera it will automaticly update the angle and the position along the camera
yourgameobject.transform.parent = Camera.main.transform;
//then maybe make some adjustments with setting the localposition of the object
yourgameobject.Transform.localPosition = Vector3 (0, 0, 0);
//and done ;)
well you have to replace the 0's with the coordinates you want to have
