C++ Virtual Method -

-

if create struct:

struct joinpoint_exception: exception {     virtual const char* () const throw (); };

what what () const throw () means in context?

what virtual member function returning pointer constant char constant , throws nothing.

virtual const char* () const throw (); |-----| <- virtual member function         |---------| <- returning pointer constant chars                     |-----| <- named                             |---| <- constant                                   |-------| <- not throw

(technically function can still throw, if does, goes directly std::unexpected, defaults calling std::terminate)

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
