2. The next function we add allows our projectiles to fire in the correct direction. We are
   overriding UpdateRotation, so that the projectiles use the pawn's rotation and not
   the camera's rotation when firing. Without this, you'll notice that projectiles always fire
   in the same direction, and towards the camera. The following is that bit of code:
   /**
   
   
   • Forces the weapon to fire in the direction the pawn is
     facing
     **/
     functionUpdateRotation( float DeltaTime )
     {
     local Rotator DeltaRot, newRotation, ViewRotation;
   
   
   
   

ViewRotation = Rotation;

/** Calculate Delta to be applied on ViewRotation */

DeltaRot.Pitch = PlayerInput.aLookUp;

ProcessViewRotation( DeltaTime, ViewRotation, DeltaRot );

SetRotation(ViewRotation);

NewRotation = ViewRotation;

if ( Pawn != None )

Pawn.FaceRotation(NewRotation, deltatime);

}
