The best way to animate multiple characters ?
Hello guys,
I am very new to animation and to Spine too. I have a few questions, which, even following the tutorials, still unanswered to me : I would like to animate two characters, but they have to interact together (for example cuddling, grabing each other, punchung, etc). What is the best way to achieve this ? Animate each one in a different file and "merge" them ? Or puth both into in a single file ?
I also have a few other concerns :
- I don't really understand how to hide a layer during the animation. For example, at frame one, I want the "open eyes" layer to be visible, and "closed eyes" to be hidden, and on frame two, open eyes hidden and closed eyes visible. When I do that, they are either hidden or visible during the whole animation...
- Also, is there a way to re-use the very first frame of the animation a few frames later ? When I try to copy/past it, the "references" are usually the frames between, why I would like it to be the frame number 1 (the original).
Please apologize for my terrible English and my noob questions and let me thank you in advance for your answers ! 
Hello mulot, welcome on the forum!
Are the two characters also sharing the same skeleton or not?
In case they share the same skeleton, pay attention to not modify them, but import the skeleton in the project to have it twice, animate the hugs etc. then import the animations from the duplicate to the original once you're done.
In case they're two separate skeletons, just import the second skeleton in the first skeleton's project, when you export them you'll get two jsons, and everything will be fine.
To hide a l̶a̶y̶e̶r (no layers in Spine) attachment, click on the dot in the first colum of the tree, the one with the eye. Don't hide the slot, because it only hides what's inside in the editor, but not at runtime, or in the preview view.
You can see how at 0:37 of this video:
You can only copy keyframes to paste in the dopesheet, so if you want to copy an in-between pose, you need to create keyframes for that pose. you can do it quickly using the shortcut Ctrl+Shift+L, that keys the current pose. You can learn more shortcuts at this page: Spine: Cheat Sheet
Don't worry 
your English was great! I hope you'll be able to create as many hugs and smooches as you want!

Can you confirm this?
The way it's represented in the editor interface led me to think it would work the same as attachments and I actually based a system I'm planing on hiding slots instead of attachments. It provided a really practical way to settle a conflict between setting attachment state on animation keyframes and using code in runtime.
Edit
Tried adding keyframes on slot de/activation and it really does not work. I guess the workaround will be using the alpha on the slot tint to achieve this.
Sorry about the thread hijack.

Hello and thank you for your answers ! I wanted to wait to try this, but I don't have much time these days and I do not want to ghost you.

They are not, I want them to have each their own skeleton.
l̶a̶y̶e̶r
Woopsie, sorry ! :angel:
Anyway thanks again for the help, even if I haven't tried, it seems it's all here to go further. I'll try that later and keep in touch if I need more help ! :angel:

A good question and a good answer. I set up a multiple-skeleton project as Erikari suggested and it works fine. It did not occur to me that I could work with animations of more than one skeleton simultaneously.
