How do I get the action at a particular frame

Hi all,

I'd like to be able to find out what action is used at a particular frame. Does anyone have any idea how to get this info? I've found the

layer:InsertAction(name, frame, byReference)

method, but no way of retrieving the value once it's set.

Regards,
Mike

No. Actions are "key frame interpolation values" or they are just ordinary key frames. If you insert a reference to an action that is a type of "key frame interpolation" (like smooth, linear, step, etc) and there is no way to get key frame interpolation using the script interface. Even if you could there is no access to what action is used either. If the action is inserted as a copy they are just regular key frames and no longer have any connection to the action that was inserted.

The only way to check for an action reference is through parsing the entire file format... I haven't quite got the hang of that yet myself.

Bum, I thought that might be the case. I think I've figured out a way to do what I wanted without mass replacing actions though

Thanks Vern.

Actually, I've been parsing the file format more recently. I think it would be possible to find out what action/s are used at what keyframes. Referenced actions are the easiest to find, but copied actions are quite a bit harder. But it could be done.

There is a sort of 'ghosting' of old keyframe values where the referenced ones are in the format. They also break the rules, so to speak. Took me a little bit to sort that out.

Let me know if you end up needing it for referenced action only, as I could probably writing that up pretty easy. Granted any file parsing relies on the state of the saved file.
