5000: The class 'Main' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.

Can you explain me what i could have done wrong? nearly did exactly the same except for the comments?

@Heckrothing Have you extended the class from the Sprite or MovieClip class on the line... public class Circle extends Sprite... That what's seems to be the problem. If not go through the code again slowly and it should work.

can you do this in cs3?

[da1bu89]

@TandHshows101 Yes you can.

[TandHshows101]

@da1bu89 i can't seem to find the create new class button... but i think you can you just create a new actionscript and type in package { ...... etc

[da1bu89]

@TandHshows101 That's correct - I'm not sure if Flash CS3 has the Project panel. If it hasn't just create a new ActionScript 3.0 file from the File menu and save it in the same folder as the FLA. Then simply copy the code from this video and everything will be identical.

At last, a decent actionscript programming tutorial, not just the usual "let's draw something and hack some code together that looks cool" shit. Thanks mate!

@da1bu89 thanks.... that works fine.
