            GUILayout.EndVertical ();
   
            SetCursorState ();
        }

First in the Start function all this three functions i’m calling not exist error message:

Reset();
SetCursorState();
OnGUI();

Then in the LateUpdate function i’m calling this function also not exist message:

UpdatePosition();

Then on this function:

void CalculatePosition(rotationX : float, rotationY : float, distance : float)
{
var direction : Vector3 = Vector3(0, 0, -distance);
var rotation : Quaternion = Quaternion.Euler(rotationX, rotationY, 0);
return TargetLookAt.position + (rotation * direction);
}

On float, rotationY : float, distance : float i’m getting identifier expected

Then in the function on the three lines: expected’;’ ex[ected ‘;’ and invalid token ‘-’…

Last this function: void UpdatePosition() i’m getting error:
Scripts\CameraScript.cs(2,2): Error CS0116: A namespace cannot directly contain members such as fields or methods (CS0116) (Assembly-CSharp)

unityscript has the type after the parameter/variable name
c# has the type first

float angle

Thanks fixed.
