How to determine if an object is at rest?

Using the physics helper library.

I'm trying to figure out how I can determine whether a physics object is at rest. Does anyone know how to do this or have any ideas of what I could do?

An example scenario is a bouncy ball that can be picked up and thrown around. I tried creating a timer that times each individual bounce from a collision event with the floor and determines if the object is at rest based off of that but this does not work for if the user slides the ball to the left and right.

Any suggestions?

  • If you have runtime access to the underlying Farseer Body, then you also should have access to the property LinearVelocity, which you can check for 0 magnitude.
