Support for AnimationAction sub-animations with startAt and endAt and units of _frames_ along with seconds

[chuckhacker]

Actually, it looks like there isn't a way of specifying a sub-animation. Right now, Blender Godot Collada exporter only supports 1 animation.

So my artists' solution is to have each animation concatenated like so:
walk goes 0 to 0.933 seconds
idle goes 0.933 to 1.833 seconds

But frames is easier to work with than seconds.

How can I play these sub animations?

Edited issue title and description to be much more clear.

@mrdoob To be clear, this isn't a Blender Exporter issue. It is a feature request for AnimationAction.

Have had similar issues - I was thinking it would actually just make sense to be able to define your actions or clips this way - ie, by feeding them start and end times (and/or frames) on clip or action creation.

AnimationUtils.subclip() should be sufficient for this use case.
