Feature: Submovieclip Support

[firebirdxxx]

At the Moment its Submovieclips are not supported. At parsetime "subtimelines" are parsed correctly. At rendertime only "maintimeline" is rendered.

@iccir I've also just hit this issue. I'm guessing, based on the last commit date to SwiffCore, that you're not working on it any more :) But any information you can share about how difficult it might be to add support for subtimelines, or where in the code would be the place to start working on it, would be really appreciated.

I haven't looked at this in awhile (it's feature complete for our uses), but, from an e-mail I sent somebody else a long time ago:

1. You need to keep track of the age of each SwiffPlacedObject per SwiffFrame, for example:
   -[SwiffFrame ageOfPlacedObject:]

2. You would have to keep a map of placed objects to ages and increment this during frame creation (in -[SwiffSpriteDefinition _parser:didFindShowFrameTag:version:])

3. In -[SwiffLayer _transitionToFrame:fromFrame:], you would need to check on the age of each placed object, and change the frame displayed by that sprite definition accordingly.

Hi,
i am the guy you send the email to. I have implemented this locally. There is still some cleanup to do, but after that i can push it. I think i can find the time by the end of next week.

Oh sweet! :) I'm not sure if I can take it in this repository (it's tied directly to our shipping product), but please post the fork!

Thanks @iccir and @firebirdxxx, both very helpful responses! @firebirdxxx, if you do push your fork up, please could you post a link here?

[firebirdxxx]

@tgjones sure i will :)

@firebirdxxx I assume you're busy, and no pressure, but just a reminder that if you do get a chance to upload your submovie fixes, it would be really useful.
