Hi everyone! i am currently going through some tutorials concerning the movement of Movie Clip in a 3d space by creating the illusion. Its fine but i have an fla file written in AS1 and using flash player 1. if i change it to flash player 9 and AS2 it does not work. They are using MovieClip.prototype.functionname = function(), may be this is the problem. What does it mean by prototype, cant get clear answer about that?? That fla explain the rotation on x y and z axis as well as zooming in and out and this is what i want to achieve! Can anyone help me please !? Thanks for any help, Jerome ---

this site… the one you are posting in… if you remove /forum, you get [kirupa.com](http://kirupa.com) and click the flash tutorials section ---

oooooohhhhhh…ok I went already through half of the tutorial, getting into panning now. But i have this fla that has been coded in AS1 and uses flash player 5. I have done some research about prototype and i still cant make it work for AS2 flash player 9. There is one tutorial that says that i must use “this” keyword in front of the variables. But it still does not work… do you know what should i use… Because once i understand that piece of code in that fla i can pretty much do whatever i need to achieve. Thanks again for ur quick reply ---

The commonest reason for AS1 files not working when you target later versions of the Flash Player is down to capitalisation: [http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs\_Parts&file=00000677.html](http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00000677.html) Another common problem is undefined/undeclared variables [http://www.kirupa.com/developer/oop2/AS2OOPChangedAndAdded2.htm](http://www.kirupa.com/developer/oop2/AS2OOPChangedAndAdded2.htm) There’s info on prototypes here: [http://www.adobe.com/support/flash/action\_scripts/actionscript\_dictionary/actionscript\_dictionary371.html](http://www.adobe.com/support/flash/action_scripts/actionscript_dictionary/actionscript_dictionary371.html) [http://www.actionscript.org/resources/articles/72/1/OOP-and-inheritance-in-Flash/Page1.html](http://www.actionscript.org/resources/articles/72/1/OOP-and-inheritance-in-Flash/Page1.html) ---

Sorry randomagain, i might sound as an idiot but i am very confused now. I have gone through your links, but i’m still confused. Do i have now to create an external class and use # include … How can i get rid of those .prototype stuff.
