Convert UnityEngine.Vector3 to float [SOLVED]

[anon20000101]

Script:

function Update () 
{
var distance = rigidbody.velocity * 2;
Camera.main.orthographicSize = distance;
}

Error:Assets/Scripts/Bubble.js(56,32): BCE0022: Cannot convert 'UnityEngine.Vector3' to 'float'.

How could i solve this problem?

[CaptainKiyaku]

var distance = rigidbody.velocity * 2;

this returns a Vector3. But orthographicSize is a float variable.
So you could use something like distance.x

But what exactly do you want to achieve?

You can use rigidbody.velocity.magnitude for what you want. Because rigidbody.velocity represents velocity as a 3 dimension vector(as in physics) but magnitude is the velocity in the sense we use in common life.

That when the object moves faster the camera zooms out.

Thanks, that worked perfectly !!!
