Subject Re: About FDB
Date Thu, 11 Dec 2014 00:22:29 GMT
Sorry, sometimes my communication skills leave to be desired... I'll do my

1.- Setting values: Right now FDB only allows to set the value of simple
variables (numeric types, strings, and booleans). I improved some debugging
features in FlashDevelop, like live edition of variables, however, not
being able to modify the value of any object variable makes this feature
quite limited when it could be quite useful for everyone.

2.- Type checking: You cannot get the type of a variable through FDB, you
get the type of its value, calling variable.getValue().getType(). The
available values are listed in VariableType:


  When a String is null you cannot know it's a String, since the type of
the value is 6 (NULL), this is a problem because allowing the users to
modify some null variable may mean they are trying to change some Object,
and when doing so the player could even crash.
