Could someone write me a 'zoom' script?
Could someone to write me a script to make a gun zoom in when you hold down Z then when you release Z it zooms back out.What I need is a machine gun zoom,the kind on halo.
Plus, I need to know what kind of script I would write it in and what object the script would be in.
I would really appreciate any help I can get,Thanks.
Please read the FAQ. Asking people to write scripts for you is not the purpose of this site.
You want something like this:
function Update()
{
if (Input.GetKeyDown("z"))
Camera.main.fieldOfView = 10;
if (Input.GetKeyUp("z"))
Camera.main.fieldOfView = 90;
}
If you want that zoom effect to interpolate over, say, a littel over a second, that's also easy
var fov = 90;
function Update()
{
if (Input.GetKeyDown("z"))
fov = 10;
if (Input.GetKeyUp("z"))
fov = 90;
if (Camera.main.fieldOfView < fov)
Camera.main.fieldOfView++;
if (Camera.main.fieldOfView > fov)
Camera.main.fieldOfView--;
}
There's ways to adjust the speed, let me know if you need that.
In general, doing small fixed changes (like ++ / --) is not portable, since it varies with framerate. A simple portable pattern is to add/subtract a multiple of Time.deltaTime.

For all you jerks saying that im being spoonfed, just shut up!Im new to scripts I have no idea how they work. Im only 12 years old, and if I don't ask these kind of questions I'll never learn anything.
And I don't really care what this forum is for. I tried to write the script myself but I couldn't, so I asked for some help. Im just glad one of you had the decency to acually write something useful, which is the point of having a forum anyway!
Thank you DaveA. Im glad you understand the differance between help and insults.
This isn't a forum. As I said, read the FAQ. This is a Q&A database for specific questions; polluting it with off-topic stuff makes it worse for everybody. Learning to script is good, but don't ask people to write scripts for you here. If you want to use a forum, go to a forum, such as http://forum.unity3d.com.
Not a spoon feed community, but if you ask more of a specific question people are more than willing to help. Ex for when you press z if(Input.GetKeyDown("z") { //zoom camera } You need to make a nested if statment if you know what that means.

Hey you can use the following script if you want to zoom in 2d . this is pinch to zoom.
float previousDistance; float zoomSpeed = 8.5f;
float minZoomOut = 1;
float maxZoomOut = 15;
GameObject selectedObject;
void Update()
{
if (Input.touchCount == 2 && (Input.GetTouch(0).phase == TouchPhase.Began || Input.GetTouch(1).phase == TouchPhase.Began))
{
// calibrate the distance value;
previousDistance = Vector2.Distance(Input.GetTouch(0).position, Input.GetTouch(1).position);
}
else if (Input.touchCount == 2 && (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved))
{
float distance;
Vector2 touch1 = Input.GetTouch(0).position;
Vector2 touch2 = Input.GetTouch(1).position;
distance = Vector2.Distance(touch1, touch2);
//camera based on pinch/zoom
float PinchAmount = (previousDistance - distance) * zoomSpeed * Time.deltaTime;
if (Camera.main.orthographic)
{
//Debug.Log("PinchAmount Val is "+ PinchAmount);
Camera.main.orthographicSize = Mathf.Clamp(Camera.main.orthographicSize + (PinchAmount * 0.05f), minZoomOut, maxZoomOut);
}
else
Camera.main.transform.Translate(0, 0, PinchAmount);
previousDistance = distance;
}
}
