Best practise to transfer object characteristics

    Hi folks,

    usually there are different ways to perform a task and sometimes I'm unsure which one to prefer.

    E.g. like these two ways to transfer the rotation from one object to another in Python.

    Way 1:


    Way 2:


    The outcome is the same here but is one way better than the other and why (e.g. performance-wise)?

    I'd intuitionally tend to the first method but I'm not absolutely sure if it is really superior to way 2.

    Any hints?

    Kind regards,

    This is covered some on a cineversity wiki page, although it doesn't use the exact examples you have:

    They don't get into object methods like SetRelRot(), so it'd still be interesting to find out if there's a big difference there.

    The fastest way is the first with SetRelRot().

    darby linked an interesting page on Cineversity wiki, where there's a nice explanation why using the subscript operator [] is slower.

    In the end, performance isn't so important for most scripters and using [] isn't wrong for object's parameters.

    Hi Darby and Yannick,

    thank you both of you, also for the wiki link.
    So I had the right feeling indeed. 😉

    Kind regards,
