Jan Stránský proposed the following answer: Hi Varun, > For translation, I was trying to use > > for s in sp: > s.state.pos[0] = s.state.pos[0] - 1.9603017657 > s.state.pos[1] = s.state.pos[1] - 1.04086 > s.state.pos[2] = s.state.pos[2] - 2.01932 > > which doesn't work. > You have to assign all pos at once: ########################## b = sphere((1,2,3),1) b.state.pos[0] = 10 # does not work b.state.pos = (10,2,3) # works ok b.state.pos = b.state.pos - (1.96,1.04,2.02) # also works ok ########################## > > Then, I noticed from the Yade user manual that there is a function > translate((Vector3)arg2) which translate all spheres by given vector. I > tried using it as: > sp.translate(-1.96030,-1.04086,-2.01932) > > but this gives me the error: AttributeError: 'list' object has no > attribute 'translate'. Mostly, I am using it wrong.

But the first approach works ok, so no need to use this function cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
