That suggests to me that the collision geometry is being successfully added, but that there’s a problem with the code that sets up the collision-handler.
If you want an example of setting up some collision geometry, as well as setting up collision-events and a collision-queue, you might look at my “beginner’s tutorial”, specifically the lessons that cover the collision system. Starting here:
In this case, actions are animations.
I don’t think that there’s a means of exporting just one action. But you could always experiment; perhaps it can be done by selecting just one action, then exporting by key-frames rather than by selecting “All actions as animations”.
Exactly, yes.
I believe that the YABEE “how-to” document (which should be found on the same GitHub page on which YABEE is hosted) includes a screenshot that shows it.
When you switch between actions in Blender, you should find that the timeline updates to reflect only the key-frames belonging to that action, I think.
It might be worth looking up a Blender tutorial on creating actions, as describing the process here could become tricky (lacking screenshots or video), and a little lengthy.
But in short:
- In Blender, open the “Dope Sheet” panel. (From the list of panels that includes the 3D view, UV/Image editor, Properties panel, and so on.)
- From the drop-down to the right of the various menus in that panel, select “Action Editor”.
- Now, for each animation:
- Go to the section just to the right of the above-mentioned drop-down, and add a new action.
- Name this action; the name given should end up as the name of the animation.
- Click on the button labelled “f”–this prevents the action from being removed if Blender thinks that it’s not being used!
- Insert key-frames as usual; with the action selected, they should be assigned to it.
