Mass and Center of Mass? Missing API?

[StudioTatsu]

Has the API Docs been updated for softbody? I may be overlooking it or using an outdated link.

Before I write my own methods, I have a few questions:

I'm replacing my rigidbody with a softbody. Do these methods/fields or something equivalent exist for softbodies.

1. Rigidbody.GetPointVelocity(Vector3 worldPoint) - returns the pointVelocity .
   
2. Rigidbody.AddForceAtPosition(Vector3 force, Vector3 position)
   
3. Rigibody.centerOfMass - get and set the center of mass of softbody.
   
4. Rigibody.mass - [i]get and set the total mass of softbody.[/i]
   
5. Rigibody.velocity - gets the softbody velocity 
   

I have been working on alternative approaches just in case the above methods/fields don't exist. so far...
for setting mass: I was going to divide the total mass with the particle count and add that value to each particle.
for getting velocity: since each particle has a velocity, I was going to use the first particle as the velocity.
 but does a single particle velocity represent the velocity of the entire softbody? Not sure this will work.


And Lastly - Since you have to initialize a softbody in the editor, It's not possible to create a softbody at runtime, right?

I'm in the dark and guessing without the softbody API documentation (using the source helps, but creates more questions).

 Any help would be greatly appreciated.

Thanks.
