V. you would need a separate vector<Force> vector<Moment> etc.. for each type of physical action to do that. If you just store raw pointers in a vector it won't work (you know why ;). You cannot store different types of actions without pointers - because only pointers (shared or not) provide the polymorphic behaviour. The only alternative is to have vector<vector<Vector3r> >, and remember that 0th column is Force, and 1st column is Moment .... In fact we already remember that - it's the classIndex(). I don't know how good/useful it might be, though. And not possible currently without some extra work, I recall that come physical actions are overly complex currently (their data is bigger than sizeof(Vector3r)). -- Janek Kozicki | _______________________________________________ Mailing list: https://launchpad.net/~yade-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
