This can't work as on deserialize it would need to have the type for IUserData already. And that's impossible with the way it's used right now. Would need some kind of factory or so probably, but I'll ignore this for now. Note that it's still possible to call some serialization manually on the derived classes by adding it there if needed. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6568 dfc29bdd-3216-0410-991c-e03cc46cb475
