[Visualpython-users] pass by value?

[Richard C. <ax...@ch...>]

hi

how do you make sure a variable a vector in this case: is passed by value as
opposed to passed by reference.

i have a class and in the class i have a list of positions, now i have a
function called addposition which takes in a item called pos. in the
function call i set pos=shape.pos, but when i move my shape.pos to something
else eg shape.pos + vector(1,1,1) it changes all the positions i entered
into the list to this value.

how do i stop this happening

thanks

richard
