Editing custom classes + external scripting files as3
hey everyone!
i'm new scripting in general , as3 in particular. current project @ standstill , i'm hoping out there can point me in right direction. please bare me while explain problem best can...my terminology may make of want scratch eyes out...sorry in advance.
here's issue:
i've purchased as3 scrollbar component online in order scroll movie clips have used scroll dynamic text. each scrollbar instance used in separate swf (bio.swf , samples.swf) which, in turn, loaded main movie (start.swf). both individual swf's preview beautifully on own....no scroll issues or errors. load them main start movie, content shows fine scrollers don't work. click on "tracker", follows mouse around page , sticks until click 1 of nav buttons exit different page.
there external script file associated scrollbar that, understand it, needs in same place swf's. there caurina file came scrollbar told file shouldn't need referenced. regardless, have both script files in main source file. have been told may "class" issue may "re-cursive"(?) issue.
to me, seems swf losing path external script once it's loaded secondary movie.
please find below script i've used within each swf in external swf. can me? options...in beginners terms?
this script have within bio , samples swf's:
sb1.init(vidscroll_mc, "easeoutback",2,true,2);
this script appears in external scrollbar.as file:
