How to animate zooming in of the camera?
I would like to achieve the zooming in of a camera like aim down a sniper scope over time. Here is my current script.
class FieldsOfView { var narrow : float; var wide : float; } var fieldsOfView : FieldsOfView;
var delay : float;
function Update () { if (Input.GetKeyDown("f")) { StartCoroutine(ChangeFieldOfView()); enabled = false; }
}
function ChangeFieldOfView () { yield WaitForSeconds(delay); camera.fieldOfView = camera.fieldOfView == fieldsOfView.narrow ? fieldsOfView.wide : fieldsOfView.narrow; enabled = true;
}
It's easier to animate your sniper using Unity's Animation Timeline

How to animate fieldOfView in Animation timeline ? Details please
You probably want to have a shot with the Lerp function:
http://unity3d.com/support/documentation/ScriptReference/Mathf.Lerp.html
I've used this recently to control the field of view to get a similar effect.
EDIT
For example you could try:
camera.fieldOfView = (Mathf.Lerp(fieldsOfView.narrow, fieldsOfView.wide, Time.time), 0, 0);
Try this...
var fZoomDuration: float = 1.0; // This determines how fast the zoom will be. Lower values mean faster animation. var fOneOverDurationToZoom: float = 1.0 / fZoomDuration;
var fStartValue: float = camera.fieldOfView; var fEndValue: float = camera.fieldOfView == fieldsOfView.narrow ? fieldsOfView.wide : fieldsOfView.narrow;
var fTime: float = 0.0; var fLerp: float = 0.0;
while (fLerp <= 1f) { fLerp = fTime * fOneOverDurationToZoom; camera.fieldOfView = Mathf.Lerp(fStartValue, fEndValue, fLerp); fTime += Time.deltaTime; yield; }
