Cannot save runtime skeleton.

[GoogleCodeExporter]

What steps will reproduce the problem?

I was using the ozz::io::OArchive to try saving a runtime skeleton. Works fine 
for raw skeletons and runtime animations.

Here is the error message:
/usr/local/include/ozz/base/io/archive.h: In instantiation of ‘void

I forgot to mention. Its a compiler error. :P

Thanks for posting this issue.

According to this error string "with _Ty = ozz::animation::Skeleton*" it looks 
like you're saving a pointer to an ozz::animation:: Skeleton, instead of saving 
the object itself. Ozz can serialize objects and arrays of objects, but not 
pointers.

It seems to be a frequent mistake with ozz archives, maybe I should find a way 
to prevent it or document it better. What do you think?

Thanks for the quick reply!

I also wanted to add that runtime animations give the same.

Regards,

Have you tried to save the ozz::animation::Skeleton instance instead of it's 
pointer? It should fix the compiler error, same for the animation.

Yep! It all works now. Thanks!
