how to make an object an actor?! the button from 2.25 is gone, so where can i do it?!
it will reappear after you turn on physics in the world buttons.
DOH!
Man, I’m sorry for such a question, but I just couldn’t figure it out 
you should have searched
the same thing was true with 2.33, and has been asked several times
I think it is like this because in future versions there will be a selection of several physics engines (like in Tuhopuu).
