The garbage collector maintain every GcResource object, which includes as_object and all descendants. GcResource instances register themselves at construction time and gnash model only supports registration with GC happening in main thread, that is the same thread that created the GC instance. If you get that assertion failure I guess you're trying to execute ABC blocks at parse time, as the parser runs in a separate thread. What you should be doing is defining a class like DoActionTag (see libcore/swf/DoActionTag.h), that is a ControlTag. ControlTag instances are executed by main thread when the playhead enters the frame containing it. You'll just have to register the ControlTag with the movie_definition containing it (addControlTag, see DoActionTag::doActionLoader)) and provide an execute() method. --strk; _______________________________________________ Gnash-dev mailing list [email protected] http://lists.gnu.org/mailman/listinfo/gnash-dev
