Blender multiple animations and Collada export

Question

Say I have a simple mesh in Blender, with two keyframes, like so:

Then, another animation for the same mesh, also with two keyframes:

Theese animations worke fine in Blender and I can switch between them in the Dopesheet, where they are called "actions":

The problem arises, when i try to export this to the Collada format, for use in my game engine. The only animation/action that seems to be carried over, is the one currently associated to the mesh. Is it possible to export multiple animations/actions for the same mesh, to the Collada format?

Answer 1

The Collada exporter in blender does not support what Collada calls "animation clips", so only the current animation will be exported. You have a few options I can think of:

1. Fix the exporter (or convince someone to do it for you).
2. Write a script that loops through the actions and exports a new file for each action.
3. Use the NLA editor to create a track that has all the actions in sequence.
4. Export to another format that is easier to work with.

Obviously the first choice would be most appreciated by everyone else coming across this problem in the future.

Answer 2

since i'm not using blender i can only guess :)

but i think you would have to "bake" it into one single action, say you have the first animation from frame 1 to 10 and the second animation frame 20 to 30 or something and then define in the game engine where to start and stop!
