How to set initial camera angle in rotation (x,y,z)?

Unity Engine

I’m doing a camera viewing around with translation and rotation. I want my camera to go back to initial position and the viewing angle, allow me to loop the camera again and again, going through the same path.

how do I set the angle view of camera in initial position?

The easiest way to do this is to save the initial rotation in a variable of type Quaternion. Then, you can restore that rotation whenever you need to:-

var initRotation: Quaternion;

function Start() {
  initRotation = transform.rotation;
}

  ...
transform.rotation = initRotation;
