Help with getting velocity...

I have an empty GameObject that's being moved from one position to the next via Mathf.SmoothDamp. I'm trying to have the camera match its speed. This is what I have so far but I can't get the velocity readings from the rigidbody when the gravity is turned off.

Empty Object script (And the object does have a rigidbody attached)

Code (csharp):

1.  
2. var howFast:Vector3;
3.  
4. function Update()
5. {
6. transform.position.x = Mathf.SmoothDamp(transform.position.x,target.position.x,currentV,smoothTime,maxSpeed);
7. transform.position.z = Mathf.SmoothDamp(transform.position.z,target.position.z,currentV,smoothTime,maxSpeed);
8.  
9. howFast = rigidbody.velocity;
10. }
11.  

Is there a better way to get the velocity of an object or a better way to have the camera match the same speed as an object, that's not Camera.main.transform.position = target.position and also only relative to Space.World?

 

You can't get anything out of .velocity if you're moving an object manually. You need to apply physics forces for that (including gravity).

That's what I figured. What is the best way I can match the velocity/speed of an object and apply it to another?

 

Code (csharp):

1.  
2. var pseudoVelocity = Vector3.zero;
3.  
4. private var lastPos = Vector3.zero;
5.  
6. function Awake(){
7.   lastPos = transform.position;
8. }
9.  
10. function Update(){
11.   pseudoVelocity = transform.position - lastPos;
12.   lastPos = transform.position;
13. }
14.  

And Bob's your uncle.

 

Code (csharp):

1. pseudoVelocity = (transform.position - lastPos) * Time.deltaTime;
