How to get the velocity of my KinematicBody, animated by an AnimationPlayer?

Question

Hi...,

I've animated an KinematicBody with an AnimationPlayer translation property.

How to get the linear (and angular) velocity of the KinematicBody?

Thanks

Mike

P.S.: I need the velocity to move my player (a RigidBody) accordingly with my platform (KinematicBody) by code.

Answer 1

See an answer about changed position https://godotengine.org/qa/112705/detecting-linear_interpolation-movement
Basically velocity = (position - old_position) / delta

However you should not move RigidBody with velocity. You should use forces and impulses.

And typically, when a RigidBody rests on a moving KinematicBody it just moves together with platform: you don't have to do anything extra, like in real life.

Hi sash,

thank you for the link and the basics, this could help.

My RigidBody is a Sphere, and doesn't rest on my moving KinematicBody. I have to glue it to the KinematicBody somehow, I think the best way is to copy velocities from the KinematicBody to the RigidBody, but KinematicBody has no velocity properties.

Cheers

Mike

P.S.: Yes, the Sphere should use real life physics, but not on moving platforms.
