Hi,

I have to determine the Velocity of several objects in the scene.

Of course I could store all positions in a list and check them again when the plugin is executed again in the next frame. But since I can access the previous Matrix and also the velocity of objects from within XPresso, they must already be stored somewhere. But where?

Thanks for help & tips!

Greetings,
Jack

Afaik this is a property of the XPresso object node only. You would have to program your own history stack.
