如何动态地向时间轴添加帧？

Question

hate to ask but I actually need to dynamically add 240 frames to a pure AS3 project and then a stop frame on the last frame.

Yes we're back in 2009.

Why?

Because the dynamic, class driven PureAS3 application I've build (swf) is being delivered to a different media owner who's inhouse system (I kid you not) checks all Flash for 10 seconds of frames(hence 240) AND checks for a 'stop();'.

Any help greatly received - I'm assuming this is possible but drawing a blank online - mainly lots of people (rightly so) advising again using the timeline.

I personally think if you're not leveraging the timeline, you're working too hard. Just all the drudgery involved in positioning and sizing things that you can just put on stage feels like a massive waste of time. I think it's a shame Adobe was so focused on Flex during the release of Flash 9 that they never showed people how to keep the timeline and still have a nice class-based architecture. But that's water under the bridge and you have what you have.

Have you tried just extending the timeline and putting a stop() frame script at the end? If there's nothing on the stage anyway, adding more frames of nothing shouldn't cause an issue, nor should stopping at the end of nothing.

Another thing you could try is having a main timeline with a stop() on frame 1. On frame 1 put a MC that has the Class you are currently using as your Document Class assigned as its Class. As long as you haven't done anything weird where Classes are reaching up to root or trying to know about things they shouldn't, that should also work.

Create a new SWF as a wrapper, with those 240 frames on its main timeline, the 241st frame should contain a stop() call and an instance of your project's Main class. This SWF should be validated with whatever engine they have, but retain all the functionality of your pure AS-driven project.
