I'm trying to get the velocity of how to get either of the VR Controllers so that it can be applied to another object when hit. I cant figure out how to aquire the velocty with the SDK setup. Any help please?
I don't think there's a centralized place from which that value is provided, but there are tools available that will help you calculate it. For a simple calculation, you can just monitor displacement over time directly --- for example, `(controllerPositionNow - controllerPositionATenthOfASecondAgo) / 0.1 seconds`.
If you want something more sophisticated, take a look at RANSACVelocity.cs (in the essentials package > Runtime > Scripts > Throw). This is how ISDK itself calculates velocities for throwing --- you can see this usage in Grabbable.cs --- but it should be usable for calculating good, noise-resilient velocity estimates of other things too, including controllers. I don't think there's much documentation about that file yet, but if you're interested and have questions, either I or @LucaMefisto should be able to help you dig deeper.
Getting the velocity of a VR Controller can be done in different ways. You can directly query it in OVRInput using (note that it is local to the tracking space): `OVRInput.GetLocalControllerVelocity`.
Alternatively, if you want to do it without OVR and filter out possible noisy data you can use the InteractionSDK RANSACVelocity.cs class. You will have to create a component that makes use of it and attach it to a Controller thought.
Roughly speaking:
```
public class ControllerVelocity : MonoBehaviour
{
//create the velocity calculator with a small memory to store
//the last few pose samples
RANSACVelocity _velocityCalculator = new RANSACVelocity(10, 2);
private void OnEnable()
{
//reset the calculation everytime you enable the component
_velocityCalculator.Initialize();
}
private void Update()
{
//feed a timed pose every frame.
//Assuming this component was parented with the controller transform
