[SOLVED] RigidBody : How to get Velocity?

[TheOmnisimush]

In Unity, apart from setting Force to a RigidBody, e.g : RigidBody.AddForce(Vector3, ForceMode)
you can also get current velocity of a moving RigidBody.

Unity Script reference :

• RigidBody.velocity { set; get; }
  Unity - Scripting API: Rigidbody.velocity

• RigidBody.GetAccumulateForce()
  Unity - Scripting API: Rigidbody.GetAccumulatedForce

• RigidBody.GetPointVelocity()
  Unity - Scripting API: Rigidbody.GetPointVelocity

Meanwhile, I can not find a “GET” method for RigidBody class in Flax.

• Class RigidBody | Flax Documentation

Is there any way to get the velocity or force of a moving RigidBody in Flax ?

You should be able to use rb.LinearVelocity and rb.AngularVelocity (where rb is your RigidBody) to get and set the velocity vector. I see it appears to be missing from the docs though.

Hey, you are right.
I guess I missed those properties when I code, thanks for your help!

The difference between Unity’s and Flax’s physics APIs can be confusing. Unity’s Rigidbody provides simple access to velocity, but Flax might require using physics debug tools or tracking frame deltas to calculate movement speed.
