CloseThe field of view of the camera in degrees.
This is the vertical field of view; horizontal
Field of view varies depending on the viewport's aspect ratio, for more information see VerticalToHorizontalFieldOfView.
Field of view is ignored when camera is orthographic (see orthographic).
Some VR SDKs have fixed field of view values that are used for VR cameras. When VR is enabled with those SDKs, this property will always return the value from the SDK. You will see a warning logged if you attempt to set the property and the value will be ignored.
If you make changes to the projectionMatrix, the camera no longer updates its rendering based on its fieldOfView. This lasts until you call ResetProjectionMatrix.

void Start() { //Start the Camera field of view at 60 m_FieldOfView = 60.0f; }

void OnGUI() { //Set up the maximum and minimum values the Slider can return (you can change these) float max, min; max = 150.0f; min = 20.0f; //This Slider changes the field of view of the Camera between the minimum and maximum values m_FieldOfView = GUI.HorizontalSlider(new Rect(20, 20, 100, 40), m_FieldOfView, min, max); } }
