Where is the velocity ?

I'm looking for how to call the velocity of an object for a compute...

I thought it was : "name of the object" + .Xvelocity : P1.Xvelocity

But I can't access this value. :/

What behaviour are you using to move the object?

Physics (by using impulse)

object.physics.velocityX

object.physics.velocityY

for overall velocity use: distance(0, 0, object.physics.velocityX, object.physics.velocityY)

Thanks a lot !
