So after you create the Shape with new, but before you call any of the "init-with" methods, you have to call set-density. In version 2.0, this limitation will be removed. If you are calling set-density before initializing the shape and it's still not working, please send me a simulation which exhibits the bug and I'll have a look at it. > Also, I want to know if there is a method which can give a Multibody > object an instant impulse,not just the constant force. There is no explicit method to do this, though the same effect can be achieved by directly modifying the Multibody's velocity. - jon klein _______________________________________________ breve mailing list [email protected] http://www.spiderland.org/mailman/listinfo/breve
