softBody velocity

[josemendez]

I am unsure where to access the softbody's velocity.

You can't, because a softbody (like any deformable body) doesn't have a single velocity. Different parts of it can move in different directions and with different velocities.

This is also true of rotating rigidbodies, however in a rigidbody you can estimate the velocity at any point using the center of mass' angular velocity (Unity's GetPointVelocity() method). However this doesn't work in a softbody, because it doesn't have a single angular velocity either.

i was able to find the solver's velocities but it return an unusable vector4 that is only usable with obi element.

That's the only way to get velocities out of a deformable body: query the velocity of its individual particles. However that's far from unusable, you can a lot of things with this. I think you're interested in finding the linear velocity of the softbody's center of mass. This is done by calculating a mass-weighted average of all particles' velocities.

There's code for this in the manual that you can copypaste (http://obi.virtualmethodstudio.com/tutor...icles.html) you just have to swap positions with velocities.

Let me know if you need help with it.

cheers!
